The invention relates to hydropower, in particular to a hydraulic inlet valve for the metered supply of fluid in the fill capacity, and can be used in systems filling with water of various kinds of containers.

Known filling float valve, comprising a housing with a horizontal suction inlet, side outlet pipe and the saddle inside front of the saddle locking element is movable in the axial direction of the rod which is kinematically connected by 2 levers with float (see U.S. patent 4108202, CL F 16 K 31/18, 22.08.1978).

This valve automatically adjusts the process of filling containers with water after emptying. However, the functionality of the valve is limited, in particular this valve does not allow you to adjust the level of liquid in the filled capacity depending on the needs of the consumer. The locking element has a complex structure, which reduces the reliability of its performance and complicates the process of maintenance of this valve, especially in cases where water may contain particles of sand or rust.

Closest to the invention to the technical essence is filling float valve, comprising a housing with a vertical suction inlet, outlet and a conical seat ADAP the ri housing, located opposite the seat locking element made in the form of an elastic membrane with a thickness in the zone of interaction with a saddle movable in the axial direction of the shaft of the locking element is placed in the bracket, which is fixed relative to the housing by means of the Union nut, and is kinematically connected via a lever with a float located with the possibility of vertical travel in the glass, the latter is mounted for adjustment of the vertical location relative to the hull, and the bottom of the nozzle hole, which is equipped with a float valve for communication of the internal cavity of the Cup with a fill capacity of the discharge of the last of the liquid (see application of the Netherlands 7009447, CL F 16 To 31/26, 29.12.1970).

This filling valve is used to maintain a fixed level of liquid in the filled container. However, this valve does not allow you to adjust the position of the float relative to the glass that narrows the filling valve.

Object of the invention is to enhance the functionality of the filling float valve and increase reliability.

This problem is solved due to the fact that filling the float valve includes a housing with a vertical suction inlet, the outlet and to nwaobasi seat inside located opposite the seat locking element made in the form of an elastic membrane with a thickness in the zone of interaction with a saddle movable in the axial direction of the shaft of the locking element is placed in the bracket, which is fixed relative to the housing by means of the Union nut, and is kinematically connected via a lever with a float located with the possibility of vertical travel in the glass, the latter is mounted for adjustment of the vertical location relative to the hull, and the bottom of the nozzle hole, which is equipped with a float valve for communication of the internal cavity of the Cup with a fill capacity of the discharge of the last of the liquid, the float is mounted for movement relative to the lever through adjusting screw, the head of which is assigned a transition bracket, bracket valve body attached with the tabs on its side surface facing the glass, and at last made a profiled ledge by means of which put on them removable clamp the glass is fixed relative to the rack, the membrane is sealed around the perimeter secured to the housing by a bracket with locking nut with education in the housing side saddle cavity communicated with the outlet and the black is C the saddle with a vertical inlet pipe, on one end of the lever is made of profiled axis. cylindrical sections which are placed in the aligned holes of the bracket body, and between the cylindrical sections on the axis is made of land in the form of a sector of a circle in cross-section axis of the rod in the middle part made U-shaped notch and the notch is placed plot the axis of the lever, made in its cross-section in the form of a sector, and the maximum width of the plot axis is from 0.8 to 0.85 width of the U-shaped recess of the stem and wide fitting sector faces the base of the U-shaped recess with the opportunity to interact with the sides of the U-shaped recesses of the rod and the center of rotation sector relative to the rod is located from the axis of the rod at the distance of from 0.27 to 0.29 from the width of the U-shaped recess at the other end of the lever is made the hole and in the hole of the lever is placed kinematically connected with it the end of the rod. the other end of which is fixed with adjustable length of pull in the transition bracket.

Performance analysis of different structures of the filling valves showed that depending on the operating conditions, there is a need to control the level of liquid in the filled container. Convergence of adjustment of position of the Cup relative to the housing and the float relative to market the Aha allows fine adjustment of the operation of the filling valve, because given the opportunity to not only regulate the level of liquid in the filled to capacity, but the force that creates float the shut-off element in the overlap of the saddle. Additional performance opportunities valve feature due to the possibility of adjusting the length of pull by means of which the lever is connected with a fixed on the head of the adjusting screw transitional bracket. The implementation of the rod with the U-shaped recess in the middle part of the stem in combination with located in this recess axis, having a cross section in the form of a sector, allows you to create simple, easily assembled and repairable construction of the valve. Not less important is the effective interaction of the stem of the locking element and float. Therefore, the design of the levers are special requirements. The execution of the lever with the axis of rotation in the form of a sector allows you to create a lever with a large difference in the length of the shoulders relative to the axis of rotation, which improves the reliability of the overlap of the seat with the achievement of the liquid medium of the specified fill level in the tank. In addition, the connection of the long arm of the lever and float through flexible rod allows you to provide free vertical movement of the float in a glass and at the same time axial vertical movement of the rod without distortions that reliably increases the th operation of the filling valve. The study was the dependence of the displacement of the stem from the movement of the float. It was found that the implementation of sector-axis arm width, component from 0.8 to 0.85 on the width of the U-shaped recess of the stem, allows you to avoid getting stuck sector in the U-shaped recess, and the location of the center of rotation of the sector relative to the stem axis at the distance of from 0.27 to 0.29 from the width of the U-shaped recess of the stem, allows you to effectively move the rod by changing the position of the lever relative to the stem.

Figure 1 shows a longitudinal section of the described filling float valve and figure 2 - type I of figure 1.

Filling the float valve includes a housing 1 with a vertical suction inlet 2, outlet 3 and a conical seat 4 within the housing 1 in front of the seat 4 locking element made in the form of an elastic membrane 5 with a thickening in the zone of interaction with the saddle 4. Movable in the axial direction of the shaft 6 of the locking element is placed in the bracket 7, which is fixed relative to the housing 1 by means of the Union nut 8, and is kinematically connected by means of the lever 9 with the float 10, located on the possibility of vertical movement of the Cup 11, and the latter is mounted for adjustment of the vertical location relative to the housing 1. In the bottoms of the cups 11 are made hole 12, which has a float valve 13 for the message the internal cavity of the Cup 11 with a fill capacity of the discharge of the last of the liquid. The float 10 is mounted for movement relative to the lever 9 by means of an adjusting screw 14, the cylinder of which is fixed transition bracket 15. On the bracket 7 of the housing 1 of the valve is attached 16 with protrusions on its side surface facing the glass 11, and at last made a profiled ledge 17 by means of which put on them removable clamp 18, the Cup 11 is fixed relative to the rack 16. The membrane 5 is sealed around the perimeter secured to the body 1 by means of bracket 7 with locking nut 8 with the formation of the housing 1 from the side of the seat cavity 19 provided with the outlet opening 3 and through the saddle 4 with a vertical inlet pipe 2. On one end of the lever 9 is made of profiled axis 20, the cylindrical portions of which are placed in the aligned holes of the bracket 7 of the housing 1 and between the cylindrical sections on the axis 20 is made of land in cross-section in the form of a sector. In stock 6 in the middle part made U-shaped notch and the notch is placed plot axis 20 of the lever 9, is made in its cross-section in the form of a sector. Maximum width S of the plot axis 20 is from 0.8 to 0.85 width S1U-shape is cut stem 6 and the wide face of the sector facing the base of the U-shaped recess with the opportunity to interact with the sides of the U-shaped recesses of the rod 6. The center of rotation of the sector relative to the rod 6 is located from the axis of the shaft 6 at a distance L, constituting from 0.27 to 0.29 from the width of the S1U-shaped notches. At the other end of the lever 9 is made the hole 21 and the hole 21 of the lever 9 is placed kinematically connected with him the end thrust 22, the other end of which is fixed with adjustable length of pull 22 in the transition bracket 15.

Filling the float valve operates as follows.

In the initial position, when filled with liquid medium, for example water, the tank is empty, the float 10 is in its lower position in the Cup 11, the rod 6 is in the left end position and the seat 4 of the housing 1 is open for admission of fluid in fill its container (not shown). On the inlet pipe 2 liquid medium through the saddle 4 and the outlet 3 enters the fill liquid medium capacity. As the filling capacity increases the level of the liquid and when the liquid reaches the float valve 13 of the latter rises and closes the opening 12 in the bottom of the Cup 11. When reaching the liquid medium of the upper edge of the Cup 11, the liquid begins to fill the Cup 11. As a result, the float 10 is beginning to emerge that causes the movement of the lever 9. Last, revolving around the axis 20 causes rotation of the sector this axis. Sector exerts on the wall of the U-shaped of vyemchatoy 6, causing it to move toward the seat 4. The rod 6 presses on the membrane 5 and the latter gradually, as the buoyancy of the float 10 moves to its thickened area of the seat 4 and eventually blocks the exit seat 4 liquid filled in the container.

When emptying fluid from the Cup 11 is drained through the hole 12, the float 10 is lowered, which causes a reverse movement of the lever 9 to its original position. As a consequence, the sector axis 20 is rotated in the opposite direction and, acting on another side wall of the hollow rod 6, removes him from the saddle 4. Under the pressure of the liquid medium under the action of the internal forces of the elastic diaphragm 5 moves away from the seat 4 and takes its original shape, releasing the exit seat 4 for a liquid medium. The filling capacity of the liquid medium is repeated, as described above.

The present invention can be used in the energy and utilities sector for the automatic filling of various types of containers.
