The invention relates to hydro and is designed for bagged filling various kinds of liquid containers, in particular flushing cisterns

The prior art discloses a filling valve of direct action, which provides quick closure to the last stage of filling of the cistern (see patent RU 2248489, CL F16K 31/24, publ. 20.03.2005). In the known construction the float is placed in the bottom of which is mounted a check valve. When filling the tank through the check valve, the glass remains dry and quickly filled with water, once the water level in the cistern exceeds the upper section of the glass. The float in this moment also quickly rises and the flow of water in toilet tank stops. The disadvantage of this valve is increased material consumption at the expense of the Cup and his return valve, as well as the design complexity from the point of view of manufacture and adjustment.

The closest in technical essence to the claimed invention is a filling valve float with bottom water supply, comprising a housing with a saddle in the form of a nozzle and the outer mounting cylinder, a rack with a bracket, formed by the inner and outer cups, and a guide rail, along which moves the float is mounted in the cavity of the rack rod, supplied oplati�individual strip and connected through a lever and rod with float, and associated with the rod elastic membrane fixed in the bracket and cooperating with the nozzle (see patent RU 2351835, CL F16K 31/24, publ. 10.04.2009). The main disadvantages of the known devices are not tight closing of the membrane after flushing and, as a result, underestimation of water consumption at each emptying of the cistern, which can reach 0.5 to 1 liter of water depending on the pressure in the distribution network. This is explained by the following: for the simplest design of the filling valve backpressure allowed leakage of the locking element in the form of drip leaks within 20 minutes after filling the tank. This corresponds to a very small expense, a water meter does not take into account, but in those 20 minutes could lead to 1 liter of water. Thus, not fast valve closure in the last stage of filling of the reservoir leads to a significant vadapathira.

The object of the invention is to eliminate these drawbacks. The technical result is to reduce uncontrolled leakage. The problem is solved and the technical result is achieved in that the float fill valve with bottom water supply, comprising a housing with a saddle in the form of a nozzle and the outer mounting cylinder, a rack with a bracket, formed by the inner and outer cups, and a guide along which moves the float, mounted in the cavity of the rack rod connected through the lever and pull the float and connected with the rod elastic membrane fixed in the bracket and cooperating with the nozzle, the membrane is fixed in the inner Cup of the bracket, which are provided with slots in the closed position of the valve communicates with an annular ledge, made on the casing surrounding the seat. The outer glass of the bracket is preferably secured to the external mounting of the cylinder by means of a bayonet joint.

Fig. 1 shows a perspective view of the float fill valve with bottom water supply;

Fig. 2 - a section a-A of Fig. 1.

Float filling valve with bottom water supply, comprises a housing 1, the elastic membrane 2, the rod 3, the rack 4, insert-extension 5, the lever 6, link 7, the float 8, tapered elastic sealing gasket 9, slash the plastic washer 10, a nut 11 and a filter 12.

Strut 4 is provided with a bracket, formed by the inner 13 and outer 14 cups. The body 1 is formed together with the saddle in the form of a nozzle 15 and a throttling sleeve is formed in the closed position of the valve annular projection 16 and the inner Cup 13 with slits. The connection strut 4 and the housing 1 is effected by means of a bayonet joint outer Cup 14 and the fastening cylinder 17, which is made on the body 1. �Poplavok 8 is moved along the guide on the rack 4.

The rod 3 is sealed by a membrane 2, which is enshrined in the inner Cup 13. On the surface of the rod 3 has a longitudinal drainage grooves that provide free gap its working end from the adjacent surface of the membrane 2 at the time of opening of the valve.

Cone spacer 9 and oblique washer 10 allow to exclude the contact of the float 8 of the walls of the tank and provide for ease of installation of the valve to the toilet tank with sloping inside walls, which greatly facilitates the work of the installer in the cramped conditions of the dressing rooms.

The valve operates as follows.

When emptied the cistern and connected to the water system valve, the float 8 is in its lower position. The result is a long lever arm 6 is tilted down, and his short arm together with the rod 3 is lifted up. Under the action of water flow, sequentially passing through the filter 12, a throttling sleeve and the Central bore of the seat 15, the elastic membrane 2 is pressed to the end face of the seat 15. As a result of water through the gap between the membrane 2 and the seat 15 through the longitudinal slit in the inner Cup 13, and also through a vertical annular gap between the fastening cylinder 17 and the inner Cup 13 will flow into the toilet tank, raising the rate of filling with water.

In existing valves, the float 8 will also need lifting�Sya up. However, in the proposed - it is up to a certain point will be in the lower position and will otaplivalsya in the incoming water. This happens because the membrane 2 is made integral with a gasket in the inner Cup 13, generates under the action of the throttle pressure in the chamber around the nozzle 15 effort up and preventing the lowering of the rod 3 downwards and lifting of the float 8. Pressure in said chamber caused by throttling the flow of fluid passing through a longitudinal slit in the inner Cup 13. The float 8 will be in the lower position until such time as applied to the rod 3, the force from the action of the lifting force will be less than the force resulting from the pressure of water in microscale the camera on the effective area of the membrane 2.

After ascending level flush toilet will increase the lifting force of the float 8, and its present value at the contact point of the lever 6 and the rod 3 will exceed the force from the action of water pressure on the membrane 2, the rod 3 will move to a closing of the gap between the end of the nozzle 15 and the membrane 2. With the decrease of the gap flow through it will start to decrease, and thus will decrease and the pressure in microscale the camera. As a result, the float 8 will quickly rise to the upper position, the rod 3 is also relatively quickly and reliably squeeze work�second surface of the membrane 2 to the saddle 15, and filling the reservoir will cease.

At the next descent of the toilet tank, the float 8 will go down and the process of filling the tank again.

The combination of the gasket and the locking element in the membrane 2 leads to a significant simplification of the design of the valve and reduces its cost. First, there is no need to install a special non-return valves to prevent suction of water from the cistern in the water supply network during the shutoff valve on the riser water supply network (such check valves are performed or as a separate unit or combined with the filter housing, this increases the cost of the filling valve by increasing the number of parts and the use of skilled manual labor in their Assembly). Secondly, protection from infiltration of water from the cistern into the water supply system while it is off sometimes by the use of air gap flux of water. This method requires the installation of shut-off and control of the body above the maximum filling level flush toilet, which complicates and increases the cost of construction through the creation of a complex node for supplying water to the valve under pressure. In addition, when you create a vacuum in a disconnected water supply network gets it air from lavatories together with pathogenic micro�AMI, which settle on the walls of the pipes of the water distribution network and reproduce. After turning on the water riser together with settled on the walls of water pipes microbes is supplied to the water users with all the ensuing consequences. The proposed device allows to eliminate the above drawbacks. In addition, the introduction into the valve of the node delays its closing and a quick closing at the last stage of filling the reservoir tank eliminates the underestimation of the water meters of water consumed.

Thus, the proposed invention allows to reduce uncontrolled leakage and significantly increase the efficiency of the valve.

FIELD: machine building.

SUBSTANCE: present invention pertains to hydro-automation, particularly to hydraulic inlet valves with dosed supply of liquid into a filling tank, and is meant for use in systems for filling different types of reservoir with water. The filling float-valve has housing with an inlet, an outlet opening and a seat inside the housing in form of a nozzle, a gate opposite the seat, in form of an elastic membrane with thickening in the area where it is in contact with the seat. The axially moveable coupling of the gate is on an arm support. The arm support is fixed against the housing using a cap nut and is kinematically linked to the float through a lever and a tie-rod. The float is fitted with provision for vertical displacement. The perimeter of the membrane is pressed into the housing by the arm support with a cap nut, forming a cavity in the housing on the side of the seat. The cavity is linked to the outlet opening and, through the nozzle, to the inlet. There is a cavity on the arm support above the membrane. This cavity is linked to the cavity in the housing through at least one opening on the membrane. The coupling rod is pressed against the arm support using stocking type sealing rings. Inside the cavity in the housing, on the side of the seat, an encircling seat is fitted, forming an annular gap, as well as a throttle insertion which is in form of a cup. A bypass hole is made at the bottom of the latter. The perimeter of the membrane is pressed between the bottom of the cup and the arm support. An outlet opening is made in the side wall of the cup. On the inner wall of the cup and the outer side surface of the seat there are radial ribs with formation by the latter in the annular gap, a labyrinth in the cross-section of the throttling channel.
