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 horizontal suction inlet, side outlet pipe and a cone-shaped with the utilities to configure the gnome inside located opposite the seat locking element is movable in the axial direction of the rod which is kinematically connected by 2 levers with a float located with the possibility of vertical travel in the glass, and in 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 patent Switzerland 505948, CL R 16 To 31/18, 15.04.1970).

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 and the position of the Cup relative to the valve body, which narrows the filling valve. In addition, the valve has a fairly complex system of filling cups liquid medium, which fill capacity, which can lead to delay actuation of the 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 horizontal suction inlet, side outlet pipe and a conical seat inside which is located naproti the saddle locking element, movable in the axial direction of the rod which is kinematically connected by 2 levers with a float located with the possibility of vertical travel in the glass, and in 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, and the glass is installed with the possibility of adjustment of the vertical location relative to the housing, the float is mounted for movement relative to the lever by means of an adjusting screw, the cylinder of which is fixed to the bracket with the axis, the valve body is attached with the tabs on its side surface facing the glass, and the latter is made of profiled ledge by means of which put on them removable clamp the glass is fixed relative to the rack, the locking element is designed as an elastic membrane with a thickness in the zone of interaction with the saddle, and 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 provided with a lateral outlet pipe and through the saddle with horizontal vhodnym pipe, the stem is located in the bracket, one of the levers is made stepwise, one of the steps of the lever p is by means of the hinge attached to the bracket body, in the second stage lever fork made the hole, which can move along it posted axis fixed on the head of the adjusting bolt bracket, and in the first stage of this lever is connected with the bracket body made of an oblong hole, which is placed can be moved along the hole axis, made a console at the end of the second lever, the other end of this lever console is made of profiled the axis of the cylindrical portions of 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 in the cross-section axis of the rod in the middle part made U-shaped notch and the notch is placed plot axis of the second 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 of the 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, with oblong and fork holes speed lever made parallel the but each other and the distance between the longitudinal axes of these holes is from 1.25 to 1.35 from the width of these holes.

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 the lever allows precise adjustment of the operation of the filling valve. The implementation of the rod with the U-shaped recess in the middle part of the stem in combination with the location of this notch 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. One of the levers of stepped form with oblong holes, and the distance between the longitudinal axes of these holes is from 1.25 to 1.35 from the width of these holes, and execution articulated with him the second lever console made by axis so as to provide vertical free movement of the float in a glass and at the same time axial horizontal movement of the rod without bending, which increases the reliability of operation of the filling valve. The study was the dependence of the displacement is of the stem from the movement of the float. It was found that performance of the sector axis of the second 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, 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 second lever.

Figure 1 shows a longitudinal section of the described filling float valve, figure 2 - a view I of figure 1 (increased).

Filling the float valve includes a housing 1 with a horizontal inlet pipe 2, a lateral outlet pipe 3 and the conical seat 4 within the housing 1 in front of the seat 4 by a locking element that is movable in the axial direction of the rod 5 which is kinematically connected by 2 levers 6, 7 float 8 located with the possibility of vertical movement in the glass 9 and the bottom of the Cup 9 is executed hole 10, which is equipped with a float valve 11 to message the internal cavity of the Cup 9 to fill the tank when the discharge from the last of the liquid. The Cup 9 is mounted for adjustment of the vertical location relative to the housing 1. The float 8 is mounted for movement relative to the lever through regulirovanie the screw 12, at the head of which is fixed to the bracket 13 with the axis 14. On the housing 1 of the valve is attached 15 with flanges at its side surface facing the Cup 9, and at last made a profiled projection 16 by means of which put on them removable clamp 17 glass 9 is fixed relative to the rack 15. The locking element is designed as an elastic membrane 18 with a thickening in the zone of interaction with the saddle 4. The membrane 18 is sealed around the perimeter secured to the body 1 by means of bracket 19 with locking nut 20 with the formation of the housing 1 from the side of the seat 4 cavity 21 provided with a lateral outlet pipe 3 and through the seat 4 with the horizontal inlet pipe 2. The rod 5 is located in the bracket 19. One of the levers 6 are stepped. One of the steps of this lever by means of hinge 22 is fixed to the bracket 19 of the housing 1. In the second stage lever 6 is made fork hole 23 which can move along it posted by axle 14 mounted on the head of the adjusting bolt 12 of the bracket 13. In the first stage lever 6 connected to a bracket 19 of the housing 1 made of an oblong hole 24, in which is placed can be moved along the hole axis 25, made a console at the end of the second lever 7, while at the other end of the lever 7 console made profile the line axis 26, cylindrical sections which are placed in the aligned holes of the bracket 19 of the housing 1 and between the cylindrical sections on the axis 26 is made of land in cross-section in the form of a sector. In stock 5 in the middle part made U-shaped notch and the notch is placed plot axis of the second lever 7, is made in its cross-section in the form of a sector. Maximum width S of the plot axis 26 is from 0.8 to 0.85 width S1U-shaped notches of the rod 5 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 5. The center of rotation of the sector relative to the rod 5 is located from the axis of shaft 5 at a distance L, constituting from 0.27 to 0.29 from the width of the S1U-shaped notches. Oblong 24 and fork 23 of the stepped hole of the lever 6 are parallel to each other, and the distance L1between the axes of these holes 24, 23, is from 1.25 to 1.35 width from S2these holes 24, 23.

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 8 is in its lower position in the Cup 9, the rod 5 is in the left end position and the seat 4 of the housing 1 is open for admission of a liquid medium filled in her capacity (black the hedgehog 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 11, the latter rises and closes the opening 10 in the bottom of the Cup 9. When reaching the liquid medium of the upper edge of the Cup 9, the liquid begins to fill the Cup 9. As a result, the float 8 is beginning to emerge that causes the movement of the lever 6 and the associated kinematically second lever 7. Last, revolving around the axis 26, causes the rotation of the sector axis 26. Sector exerts on the wall of the U-shaped recess of the shaft 5, causing it to move toward the seat 4. The rod 5 presses on the membrane 18 and the latter gradually, as the buoyancy of the float 8, moved his thickened area of the seat 4 and eventually blocks the exit seat 4 liquid filled in the container.

When emptying fluid from the Cup 9 is drained through the hole 10, the float 8 is lowered, which causes a reverse movement of the levers 6 and 7 to its original position. As a consequence, the sector axis 26 is rotated in the opposite direction and, acting on another side wall of the hollow stem 5, removes him from the saddle 4. Under the pressure of a liquid medium under the action of the internal forces of the elastic membrane 18 departs the t of the saddle and takes its original shape, freeing 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.
