The invention relates to a pump engineering turn out, in particular for hydraulic structures Taranov, and can be used as a water-lifting device.

Known air cap of hydracarina, comprising a housing with an air and liquid compartments, an inlet valve and fitting pressure line, a piston dividing the housing for air and liquid cavity and rigidly mounted spring-loaded rod that has a stroke limiter (USSR Author's certificate No. 1224464, CL F04F 7/02, 1986).

A disadvantage of the known device is a low efficiency due to waste energy on challenging management position of the shock valve, designated high-altitude location in the body and depending on the weight of the valve, i.e. to lift a certain part of the height you need to expend a lot of energy flow. In this part of the unproductive energy is lost to resistance in the case when a large enough weight. In addition, the air cap, provided with a piston, requires additional effort on the ascent of the piston in the housing, which requires maximum effort pressure in the pipeline, thus, part of the energy overhead is lost in the hydraulic shock to lift the fluid from the horizon in the case of the air cap. Therefore, advanced, and offered artif what I'm charging the compressor through a spiral tube in the lid, which leads to higher operating Taran.

Also known hydraulic RAM containing the supply pipe with a shock valve and discharge pipe, cap, divided by a partition in the form of a mesh into two chambers, a spring in the chamber from the side of the dome are balls made of soft elastic material filled with an incompressible medium (Patent SU # 3777 A, 31.10.1927, F04F 7/02).

The disadvantage of the closest analogue is the lack of a reliable method for controlling air volume in the air (pressure) cap. Furthermore, the efficiency of hydracarina little due to the inertia of the system shock valve, and significantly the space beneath the dome of the cap is forced to endure the process of hydraulic impact from balls, which leads to a constant pressure load on the dome and, as a consequence, the reliability of its walls, which leads to bad conditions for the strength of the dome structure of the air cap.

An overall review of the operation of the pump shows that there must be an exchange of energy between the fluid and any moving element of the device to which energy is supplied.

Thus, it should be noted that the need for such a process, disappears when the elastic cushion, which causes fluctuations of the liquid column in the inlet water pipe and creates a Hydra is symbolic blow.

The objective of the invention is to increase the efficiency of the device by increasing its reliability, as well as increasing the efficiency of hydracarina.

The technical result is achieved by the hydraulic RAM (containing the supply pipe with a shock valve and discharge pipe, cap, divided by a partition in the form of a mesh into two chambers, a spring in the chamber from the side of the dome are balls made of soft elastic material filled with an incompressible medium, in one of the cells from the fixed dome housing with cells in a checkerboard pattern with longitudinal and transverse walls, and the cells are supplied installed inside the regulatory body in the form of springs with a flat plate that is installed with the possibility of contact with the ball.

In addition, the ball with an incompressible medium filled from its total volume.

This design of the air cap is intended to keep the air in the cap of the hydraulic RAM and eliminate the constant need replenishment, as part of the air released from the water is captured by the liquid in the discharge line (pipe), in the end, due to pressure wound springs with flat plates begin to deflect balls and move out of the cells in a chamber filled with an incompressible medium in the form of gas or air, is Elisheva its volume and creating cap high blood pressure. Water flows through the pressure line (pressure tube) in a team capacity. By this time, the position of the balls takes a round shape of the ball and not allow them to fall out of the air cap. As a second option, instead of the flexible balls can be installed and the rubber diaphragm instead of a grid, which flexes up and down, displacing the liquid from the bottom of the cavity chamber of the cap into the discharge pipe to the consumer, but this adaptation differs from the original version of the runtime, as part of the energy is scattered by elastic deformation and the pump. Therefore, according to the first embodiment, the liquid (water) when the hammer has a greater volume in the air cap and are elastic balls are cells and compress the spring to a predetermined elasticity, and then to give its accumulated energy when working Tarana on the rise of water in the tank to the consumer. This new technical solution is less expensive, reliable and does the job hydrant with high efficiency. A characteristic feature of the air cap are flat plates attached to the free end of the spring. When exposed to pressure in the cap wall of the elastic balloon bending, reducing its volume, respectively, of an incompressible medium (air or gas) creates pressure on the spring compression and saves her energy for subsequent wound,resulting in the shape of a ball changes a bit for example, drop in, but not out of the recesses of memory cells that are elastic (flexible) balls, and does not allow them to deviate in cells in side by longitudinal and transverse partitions, mounted with the body to the dome of the cap. Forming a dent in the wall of the balloon can be formed due to fill from its total volume.

Figure 1 shows a schematic diagram of the hydraulic RAM; figure 2 - section a-a in figure 1; figure 3 is a cross-section B-B in figure 1.

Hydraulic RAM provides the supply pipe 1 and valve 2 hydraulic. Case 3 cylinder control valve connected to the hydraulic tubes 4, 5 of the control piston 6, respectively, with 7 remote control.

The flow switch includes a housing 8, a limited top nozzle 9 and the bottom 10 a perforated disk with holes 11, 12. Nozzles 9 is a horizontal pipe, divided by a partition 13 into two chambers 14, 15 with a return ball valves 16, 17, overlying the outlet openings 18, 19 in the upper part of the flow switch, which alternately lowered into the seat holes 18, 19. Nozzles 9 and the disk 10 are connected by a rod 20, and the outlet openings 18, 19 are placed coaxially perforation of the lower disk 10 with holes 11, 12. Each chamber 14, 15 reported through the outlet openings 21, 22 work stations 23, 24, sleep is by air bubbles 25, 26 with the discharge valves 27, 28 and discharge nozzles 29, 30.

On the inner surface of the housing 8 flow switch is placed vertical guides 31, 32, 33, 34 and inclined guides 35, 36 below the nozzle 9, and inclined guides 37, 38 above the disk 10.

Vertical guides 31, 34 are displaced relative to each other on the magnitude of impact of a ball valve 39. In addition, vertical guides connected with inclined guides, and respectively with the bases of the head and disk.

On the principle of the flow switch with the shock valve - push-pull (open, closed). In the first step with increasing fluid pressure shock valve 39 rises to the nozzle 9 in the zone opposite to one of the outlet holes, such as hole 18. With decreasing fluid pressure shock valve 39 is lowered to the disk 10 is rotated 90. In the second step with increasing fluid pressure shock valve 39 is lifted off with a 90 rotation to the nozzle 9 and closes the other opening 19 and so on takes the position opposite to the accommodation hole of the disc 10. In this case shock valve 39 is located below the seat holes 18, 19 of the nozzle 9, and the shut-off valve 16, 17 above the saddle holes 18, 19 in the chambers 14, 15, and biased shut-off valves on the opening of the inlet holes 21, 22 of the work area 23, 24.

the upper part of the spherical cap 25 and 26 rigidly mounted to the body cells made with longitudinal 40 41 and transverse partitions. At the base of the cell is fixed (clamped) the spring 42 with a flat plate 43. Spring 42 plate 43 perform the role of a supporting structural element when the elastic contacting the ball 44 in the working position, for example air cap 25, and locked in a cell with longitudinal 40 41 and transverse partitions. In order elastic (flexible) balls 44 could not fall to the bottom of the cap 25, 26, the cap is divided by a partition in the grid 45 into two chambers, interconnected, one of which side of the dome cap are elastic balls 44.

The diameter of the elastic balloon 44 is assigned structurally accordingly, the size of the cell, made in the partitions 40, 41, for example, cells in the plan is executed in a checkerboard pattern.

Furthermore, since the wall of the balloon 44 are flexible and can bend, reducing its volume in working condition Tarana, respectively, of an incompressible medium, such as gas or air, filled from its total volume. Upon contact with the plate 43 with the spring 42, the elastic wall of the ball 44 sags in the form of dents. The shape of a ball 44 is changing and not out of the recesses of the cell in which the ball 44. The material of the ball 44 may be of rubber or other elastic materials in the production of the E.

Hydraulic RAM operates as follows.

Before admission of fluid flow in the supply pipe 1 shock valve 39 is in the initial position, for example above the hole 11 in the base of the disk 10. Accordingly, in the air caps 25 and 26 there is no liquid, and the balls 44 are located on the grid 45. When closing the valve 2 in the collection of the flow in the pipe 1 is blocked and forth in the housing 8 of the thread switch shock valve 39 is fond of fluid flow and moves along a rectilinear guides 31 and 32, the inclined guide 35 at the upper part of the lower nozzle 9, sharply overlaps one of the outlet openings 19 under the action of pressure in flow switch, forming a hammer.

At the same time when filling flow switch fluid shut-off valve 17, overlying the outlet opening 19, rises in the chamber 15, the nozzle 9 up. But since the share of the shutoff valve 17 (16) is 1.05...1.1 g/cm3on average 1,08 g/cm3regarding the specific weight of water, what happens ahead of the fluid flow in the initial period. As a result, the abrupt closing of the outlet 19 of the shock valve 34 reflected wave of the fluid flow is directed in the work area 24 and then into the discharge pipe 30. When the attenuation of the energy of the surge discharge valve 28 is closed and the flow of liquid is in the working area 24 is terminated. At this time, the shut-off valve 17 is in the upper position of the camera 15, the nozzle 9, provided with a partition 13.

With increasing pressure fluid through the mesh 45 into the chamber above the grid 45 and the air pressure in the chamber increases and elastic balls 44 rises above the grid 45 and pressed against the disc valve 43 with the spring 42 and the wall of the balloon 44 sags in the form of dents, which serves to reduce hydraulic shock while decreasing the volume of a ball 44, i.e. by means of indentations formed in the upper part of the wall in contact with the flat plate 43 through filling of its total volume. This in turn prevents the formation of large impact efforts that are harmful to the strength of the dome structure of the air cap. In this case, during operation of one of the air boxes and due to the constructive parameters of the cells in the body, formed by the partitions 40, 41, supporting the conservation of the air in the cap of the hydraulic RAM. Formed an air cushion, which occurs due to compression as atmospheric air, and the elastic balls, filled, for example, gas or air, is made of flexible and durable materials. In the cells of the body no jamming (drafts) of the ball 44, and accordingly, the arrangement of cells having a spherical shape, allows about who ensure the ball 44 a stable position during operation of the air cap. When the compression spring 42 is retained additional stored energy for subsequent wound when the outflow of fluid from the air cap pressure in the pipe 29 or 30.

Upon termination of the supply fluid in the supply pipe 1 or the opening of the valve 2 hydraulic transit shock valve 39 is lowered down to, for example, to the right along the guide rails 32, 33 and 35, and is located above the other of the input hole in the disk 10, and shut-off valves 16, 17 are lowered into the socket holes 18, 19 of the nozzle 9, closing the last, working in sections 23, 24 are formed of the residual liquid. After disabling fluid and depletion of the air cap ball valves 40 are lowered to the grid 41 and restore its original cylindrical shape. This completes a full cycle of the switches, and the process is repeated in the already described sequence, and the shock valve 39 does all the time moving around the rod 20 is rotated 90.

An integrated approach in the work of the hydraulic RAM is to establish functioning elements of the proposed device in one unit and coordination of site works under the arch of the air cap.

The size with cells, springs flat plate design elastic balloon which is filled with an incompressible medium, are determined by calculation and experienced the m way.

The effectiveness of the invention is that it can improve its reliability and efficiency hydraulic RAM, this reduces the inertia action of the dome space of the hood to fractions of a second to reduce hydraulic shock elastic ball (from the body of soft material) and does not require the expenditure of additional energy.
