Self-threading siphon

 

The invention relates to a self-threading siphons with located inside hygroscopic material and can be used, in particular, to devices for watering plants from the tank with water. The device is formed of a U-shaped tube, which is placed hygroscopic material. The tube has an ascending branch, the knee and the descending branch. All descending branch or part has a larger volume than the ascending branch for placement in the descending branch of the more hygroscopic material. Descending branch of the tube is continued by using a hose with a diameter smaller than the diameter of the tube. When lowering the ascending branch in the tank with the liquid in the capillary phenomena of liquid completely wets hygroscopic material and reaches the end of the descending branch. Then a drop of liquid flow into the inlet hose for subsequent removal. The device makes it possible to bring the liquid to one or more distribution points and can be used when draining the tanks. 22 C.p. f-crystals, 13 ill.

The invention relates to a self-threading siphon, which is a combination of means having a capillarity, and its own supply of water.

The known device using capillary phenomena to filter water from any vessel. For example, in French patent N 791997 described tube in the form of an inverted U comprising a housing with dimensions selected on the basis of the action of the capillary system. One of its branches submerged in flooded into the vessel of water. Under the action of capillary pressure water rises, passing over the top of the U-shaped tube, and then again drops on her second branches. However, in such known devices, the amount of water sufficient to fill the entire tube and downward to create a suction force to allow starting of the process of filling the siphon, the water flow at the output of the device is limited by the level at which the capillarity allows water to rise in the upper part of the tube, but does not siphon the opportunity to recharge. Thus, consumption is very low since falling in the direction of the exit water does not provide the absorption of the water that goes up to the bend of the tube.

To date there is no irrigation devices, which would combine all the following advantages: the Possibility of Orosz is Ni, - with the possibility of easy automatic charging and recharging the siphon, from any tank (2), the water level which is above the location of the leak.

The aim of the invention is to achieve these benefits.

To obtain the desired results suggested self-threading siphon formed by the tube with a shape close to the shape of an inverted U, which is located inside a hygroscopic material, according to the invention descending branch of the tube is continued by using a hose with a diameter smaller than the diameter of the tube, as a result, when another branch tube immersed in a tank of liquid, and this liquid fills the branch tube to the upper level, and then continues to rise due to capillary phenomena, passing through the highest point of the tube and again dropping into the branch to the hose, the liquid forms in it pillars, which, moving under the action of its own weight, creating a suction that contribute to the charging of the siphon, if the level at the outlet of the hose below the liquid level.

The tube is preferably made from a flexible material.

The tube may also be made of rigid or semi-rigid material.

It is advisable to have two separate to the range due to capillarity, and a free path through which flows most of the fluid that is absorbed when charging the siphon.

Free circuit can be formed in the space limited by the inner wall of the tube and hygroscopic material, which optionally placed in the open with both ends sealed to the shell.

Free circuit can be formed by one or more hoses, having a diameter less than the diameter of the tube and passing inside the hygroscopic material or beside him.

Free path can be formed by a hose located on the outside of the tubing and attached to the hose, continuing the descending branch.

According to one variant of the invention at the end of the descending branch of the tube there is a knee and a horizontal section defining a chamber for storing water at the discharge of the siphon.

It is located on the outside of the tubing hose, forming the free circulation loop may be attached to the camera.

Inside the chamber can be located extension hose, continuing the descending branch, to save part of the liquid in the chamber.

The hose forming the free circulation loop, and the hose, continuing nishadas the holes, whereby fluid flowing through the capillary phenomena in the camera, you can log in hose, continuing the descending branch.

The hose forming the free circulation loop can be continued outside of the tubing with the side branches to dive into the deeper part of the reservoir.

It is advisable to siphon contains a means for plugging pipes, retaining hose, forming the free circulation loop to open when the liquid falls, approaching the level of the inlet tube.

If the location of the hose forming the free circulation loop, outside of the tubing in the entrance to the ascending branch of this tube preferably has a float valve.

It is advisable that all descending branch or part of it had a greater range than the ascending branch, for placement in the descending branch of the more hygroscopic material that allows you to create a reservoir for the liquid to recharge siphon.

Hygroscopic material is preferably a granular material such as sand.

It is advisable that the granular material was stabilized inside the tube with the structure of the lattice type, twisted tape, vol 1 to 6 mm

Preferably, the diameter of the hose, continuing the descending branch that was lying in the range of 2 to 5 mm

The diameter of the hose, continuing the descending branch, preferably equal to about 4 mm,

On the hose, continuing the descending branch can be placed valve for flow adjustment.

The granular material can be stabilized inside the tube by means of a semi-rigid plastic element in the form of a twisted tape.

It is advisable that the tube was closed at both ends hygroscopic filters, pores which are smaller than the smallest grain of granulated material.

The most distinctive feature of the invention, in accordance with its volume, limited formula, is that the siphon is charged under the action of a small amount of fluid supplied through the capillaries along the wick to the entrance of the tube into which it can flow, causing the absorption.

In the drawings: Fig.1 schematically shows one of the known irrigation device of Fig. 2 shows a first implementation of the irrigation device according to the invention, Fig.3 and 4 depict a first embodiment of the device according to Fig.2, figs.5 depicts a second waista according to the invention,
in Fig.12 shows an example of another application of the device according to the invention,
in Fig. 13 shows another variant of the irrigation device according to the invention.

As can be seen in Fig.1, the known device is formed of a U-shaped tube (9), which placed absorbent material (15). The tube has an ascending branch (10), the knee and the descending branch (8). When lowering the branch (10) U-shaped tube in the fluid (3) its immersed part quickly filled up to the level (11).

Then the liquid in the capillary phenomena rises and fully wets absorbent material (15). Entering the branch (8) U-tube under its own weight, the liquid comes to its end and flows out in the form of drops (19).

In Fig. 2 shows the device according to the invention, in which the branch (8) tube (9) is elongated with a hose (12) with an inner diameter less than the diameter of the tube (9).

Drops (19) falling into the inlet of the hose (12).

If the diameter of the hose (12) to choose small enough so that the liquid is not leaked, it will remain at the entrance to the hose (12), forming a tube.

Once dropped one or more droplets, and the liquid level was sufficient to pressure previs) liquid when lowering which is a decrease in pressure.

This decrease in pressure causes air bubbles that get into the hose. As a further fall in drops into the inlet of the hose (12) are more small posts (20) of the liquid, which creates even greater pressure.

Between these pillars liquid bubbles of air that extend from the free end of the hose (12).

This remote air is replaced by the liquid, the level of which in branch (10) tube (9) rises.

When the liquid level reaches the upper point (30), it flows into the branch (8), providing a much more intensive filling hose (12) than in the case with simple wick.

You can verify that the flow rate in the hose (12) becomes large enough, depending on the height of the fall, as the device operates in this case on the principle of the siphon.

Upon reaching the system steady-state operating mode, the output of the air bubbles stop. You can see that although in the descending branch (8) the air is still, it is not a hindrance, because this branch is the leakage of liquid, so that the suction part of the siphon will start only at the initial site above or equal to 6 mm

Extremely efficient operation is ensured when selecting the diameter of the hose (12) of order 2, 3 or 4 mm, and at values of 5 or 6 mm of the conditions necessary for the formation of the water column, some worse. The fact that water tends to flow in the form of a stream that does not contribute to charging the siphon.

This disadvantage can be partially corrected through appropriate selection of the material of the hose (12). For example, if you make its internal surface a little rough, it will contribute to water retention and consequently impede its flow.

If the diameter of the hose (12) is less than 2 mm, the moving water will be difficult, and because the amount of intake air decreases, charging the siphon will be longer and will be more chaotic, and if the diameter of the hose is less than 1 mm, then charge the siphon is quite impossible.

Another important feature of the invention lies in the fact that after wetting absorbent material (15) (or already spent the siphon, or when its wet intentionally lowering the device into the water) charging the siphon is much faster.

Indeed, when submerged branches (10) in the liquid the latter enters the tube and lift up is a few drops of water, forming in the hose pillars that contribute to the charging of the siphon. In addition, there is no need to wait until the end wetting the absorbent material, because it is already saturated with water.

When the hygroscopic material, pre-moistened, you can speed up the charging of the trap, increasing the amount of water held within the branch (8) U-shaped tube. This can be achieved by increasing the number of hygroscopic material, which are in descending branches (8).

Therefore, it may be appropriate to increase the amount of branches (8), for which it should, for example, to extend and/or expand.

You can also increase the amount of water inside the device, using an important feature of the invention, according to which branch (8) tube (9) has at the end of the knee (32) and a small horizontal section (33) defining a chamber (34) for storing water in case of pre-wetting device or discharge of the siphon (Fig.3 and 4).

In accordance with another embodiment of the invention, within the specified camera (34) is the extension (35) of the hose (12), which prevents the release of the water when the system area (33) incline relative to the deposits in the chamber (34) such quantity of water, to ensure a slight leak from a hose (12) when the return section (33) in the horizontal position.

When this water is pushed into the hose (12) under the action of pressure when submerged branches (10) in the tank, its fall causes the input of the siphon in action (the so-called "starter", or trigger that effect).

When using this device charge the siphon is possible even in adverse conditions.

For example, when the level (11) the fluid is too low in relation to the level of (30) for capillary charge, siphon however, you can recharge partially plunging into the water branch (10).

In the case of a discharge siphon due to the lack of water in the tank this measure allows you to quickly re-charging as soon as the water level rises to a sufficient value, and it is possible even after a few weeks of drought, as the probability of evaporation inside tubes of water is extremely small.

Embodiments of the
The diameter of the tube (9) must be greater than the diameter of the hose (12), since it must be placed hygroscopic material and, in addition, it should be enough empty space for the flow of water after charging the siphon.

Too the tion, which leads to an increase in charging time, and insufficient diameter reduces water consumption.

Experiments were conducted with a tube diameter of 12 mm, which helped to put the hygroscopic material without compressing it too.

It is desirable that the diameter of the mass of hygroscopic material was slightly less than the internal diameter of the tube, in order remained empty space to provide the desired flow rate during operation of the siphon.

Using the pipe (9) with an inner diameter of 12 mm, the authors conducted the following two experiments:
when the diameter of the mass of absorbent material 12 mm, when it fills the whole tube, the diameter of the hose (12) 4 mm and the height difference of 80 cm, the flow rate was equal to 2 liters per hour;
- decreasing the diameter of the mass of hygroscopic material from 12 mm to 10 mm, while maintaining the other conditions, the flow rate was equal to 11 liters per hour.

If, for the convenience of monitoring devices to use transparent tube (9), we can see how the water circulates in the free space between the tube and absorbent material.

In the various embodiments of the proposed device can more clearly distinguish the two paths of the water circulation (Fig.6).

Gyroscope is which of the gap between this shell and the inner surface of the tube (9). Thus, the water will circulate through the first loop formed by the wick enclosed in its shell. Moving due to capillary phenomena, water is fed to the inlet hose (12) and contributes to the charging of the siphon, and then, after it was charging, water circulation occurs primarily in the secondary circuit, which is the space between the inner surface of the tube (9) and the outer surface of the flexible sheath.

The charging time of the siphon is determined, among other factors, the amount to be disposed of air in the ascending branch (10) tube (9). Therefore, you should strive to ensure that this amount was as small as possible, and therefore, it is advisable to expressly limit the value of the free path for circulating water intake.

For this purpose, according to the following variant of the invention (Fig. 3), a hose (31), the diameter of which is much less than the inner diameter of the tube (9) and which is placed inside the tube along the entire length of absorbent material, so that the hygroscopic material fills the remaining empty space between the tube (9) and hose (31).

In the best embodiment of the invention shown in Fig.3 circulating water intake, able to provide the flow rate required for filing in the hose (12), even having a small internal volume.

Due to the fact that the hygroscopic material occupies the space between the tube (9) and hose (31), decreases the amount to be disposed of air, allowing for faster charging and increase consumption.

In this construction, the inlet tube (9) can be provided with special space (38) between, on the one hand, the plug (17) and, on the other hand, hygroscopic material and hose (31), which allows the flow of water on both paths.

In order to avoid clogging of the hose (31) instead of the cover plate (17) to put the grill or spongy cork.

In accordance with one embodiments of the invention to increase the water flow can be provided by two or more hoses (31).

According to another variant of the hose (31) can be continued outside of the tube (9) from the side of the branch (10), to allow suction of fluid from the area near the vessel bottom (2).

In accordance with the variant shown in Fig.13, the hose (31) is located outside the tube (9) and inserted either in the camera (34), either directly in the extension hose (12) using trego passing through the hygroscopic material may be provided by the device, which would provide the occlusion of the tube (9), when the water level drops so that the input end of the tube will not be submerged in water, while the inlet hose (31) will remain open.

At the location of the hose (31) from outside of the tube (9) is easy to install at the entrance branches float valve (42), closing the achievement of a specified level of water (Fig.13).

After charging the siphon and overlap float valve (42) the siphon continues to work up until the level (11) will not fall below the end (43) of the hose (31).

According to another variant, shown in Fig.7, hoses (31) and (12) represent a single continuous pipeline. In this pipeline, the segment passing through the chamber (34), one or more holes (36). When the capillary phenomena of water flows through the absorbent material in the chamber (34) and fills it to the hole (holes) (36), it gets into the hose (12) and, falling on it, creates a suction in the hose (31). Thus begins the circulation of water in the hose (31) and then to the hose (12), which corresponds to the beginning of the operation of the device according to the siphon principle.

An important characteristic of the device shown in Fig.3, is that after suppervised level at the output hose (31).

Thus, the siphon formed by the hose (31), in which the suction ability of the hose is combined with suction capability of the hose (12).

This is especially advantageous in cases where the head is small (for example, if the tank is used flush tank, and be watering the plants in the boxes on the ground).

In all the above cases on the hose (12) can be mounted crane (14) to adjust the flow.

In accordance with one variant of the invention, the absorbent material (15) may be a granular material such as sand.

That this material was held water, it should not be too compacted. From this it follows that it can slightly move inside the tube (9), resulting in empty space, and water cannot overcome this discontinuity.

To eliminate this drawback, in accordance with one of the most important characteristics of the invention, the stabilized sand in the internal volume of the tube by means of special restraint designs.

In the exemplary embodiment shown in Fig.8, the sand is given stability by using semi-rigid (e.g. the Vanir and other devices for example, the internal wall of the tube may be made rough or it can be performed pins, protrusions or grooves.

It is advisable to run the tube with sand transparent, so you can check whether it is filled with granular material.

In the example shown in Fig.10, the granular material (15) is stabilized by a semi-rigid plastic element (5), which is pre-curled ribbon, which is then inserted into the tube.

This twisted tape is made sufficiently flexible so that it can enter into a curved knee, and it will take all of its curves.

The tape shown in Fig.10, has a width of 10 mm It is made of a thermoplastic material, curled in a hot condition to obtain a spiral shape with a pitch of 16 mm

Twisted tape put into a curved elbow having an inner diameter of 12 mm, while maintaining a small gap between the edges of the twisted tape (5) and the inner wall of the tube. Then the tube can easily fill granular material which will move, turning around the spiral.

Tube having a curved knee, shown in all the previous note is which are smaller, than the smallest grain of granulated material.

These hygroscopic filters are held in place with plugs (17), in the centre which made the hole (18).

Opening one of the plugs has a size comparable to the size of inserted his cock (14).

Given that after the discharge of the siphon, it is desirable to keep the inside of the tube as much as possible the amount of water to speed up the process of charging, the tube (9) plug on the end caps (17), with only one hole with a diameter equal to the diameter of the hose (12) (Fig.11).

Self-threading siphon according to the invention is used in all the numerous cases when it is required to bring the liquid contained in the vessel (2), to one or more distribution points.

The proposed siphon is designed for watering plants, for example, from a reservoir with a constant level type flush tank, the consumption of water regulate by means of the valve (14) in the range from zero to several hundred liters per day depending on the amount of water the plants.

At the end of the hose through which the water flows, you can wear a porous hose, which can be either empty, or filled with sand. Thanks so much water will not leak at one point army type of garden boxes.

Porous hose can be made of textile material or of rubber to give it the necessary flexibility.

The device according to the invention can also be used as overflow siphon vessel type aquariums or simply for the purpose of emptying.

Although in the above examples, the tube (9) is made of rigid or semi-rigid material, it may be a flexible hose, filled with hygroscopic material, through which, if necessary, will be skipped hose (31).

In these cases, it can be used to remove puddles on the terraces (82), as shown in Fig.12.

In this part (10) tube (9) can be laid along the terraces to its lowest point, and the second part (8) to which is attached a hose (12), will be suspended out from this terrace.

In addition, the device can be used when draining the tanks swimming pools.
