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, in particular, the flush tank for a toilet bowl.

Known float valve, comprising a housing with a horizontal suction inlet, side outlet pipe and the saddle inside front of the saddle locking element movable in the axial direction, the spindle of 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 by the technical nature of a valve, comprising a housing with inlet and outlet nozzles and a cylindrical seat, the locking element interaction is adequate with a saddle glass installed in filled liquid tank, in the bottom of the nozzle hole, which is equipped with a float valve for communication of the internal cavity of the Cup filled with a liquid capacity of the discharge of the last of the liquid, and a float located with the possibility of vertical movement in the glass, and the inlet of the valve body is communicated through a flexible pipe is installed in the wall filled the tank inlet, and a valve body configured to fasten to the bottom valve of the descending liquid from the tank (see application UK 2245910, 15.01.1992).

This valve allows you to maintain a fixed level of liquid in the filled container. However, the use of the locking element in the form of rod, the sealing elastic ring cuff and moved relative to the valve seat float, leads to the necessity to use a large enough float to overcome the water pressure coming through the seat when filled to capacity, and the necessity of using sealing elements on the movable rod leads to a decrease in the reliability of the valve.

The technical result, which directed the present invention is to increase the reliability of the filling valve.

The specified technical the ski is achieved due to the fact, the valve includes a housing with inlet and outlet nozzles and a cylindrical seat, the locking element interacting with the saddle, the glass installed in the fill liquid containers, the bottom of the nozzle hole, which is equipped with a float valve for communication of the internal cavity of the Cup filled with a liquid capacity of the discharge of the last of the liquid, and a float located with the possibility of vertical movement in the glass, and the inlet of the valve body is communicated through a flexible pipe is installed in the wall filled the tank inlet, and a valve body configured to fasten to the bottom valve of the descent of liquid medium from the container when this cylindrical saddle is made in the case with education around him annular cavity is in communication with the suction inlet in the housing for cutting a cylindrical seat concentric with the most recently executed two annular ledge, the locking element is designed in the form of a flat elastic membrane, the diameter of which corresponds to a diameter greater degree annular ledge, elastic membrane embedded in the body at last, on the membrane in the area of interaction with the saddle on the back relative to the seat side of the fixed membrane sleeve, larger in diameter stage annular ledge installation is Lena lid made in her bottom jutting out of the nozzle and the outer side wall - a cylindrical flange on the outer side surface of the housing concentric with the saddle, made the thread, elastic membrane is tightly pressed on the periphery of the ledge larger diameter casing cover by means of a cap nut mounted on the cover with an emphasis in the cylindrical flange and screwed on the body threads, using a flexible membrane cavity cover is separated from the annular cavity of the housing, the cavity cover is informed through the nozzle with the surrounding valve space and through the hole in the membrane and the membrane of the sleeve with the annular cavity of the housing, the cover is made with two brackets, using one of the brackets can be rotated relative to the cover secured to the lever at one from the ends of which are mounted valve with the possibility of overlapping the last of the nozzle cap and the other end of the lever is kinematically connected to the shaft on which are fixed the float can move relative to the thrust, and through another bracket on the lid attached to the short side l-shaped stand, a vertical long side of which is made with a saw-tooth comb on its lateral surface and on the side stand has a glass, and the glass along its side wall made of rectangular cross-section channel, the wall of which is made podrug the United relation to the speaker inside the channel thorn hour and filtered through a channel can move Cup relative to the rack and through the cleat, interacting with saw-tooth comb, fixation of the Cup relative to the rack.

Analysis of different designs of valves has shown that it is possible to improve the reliability of the valve by simplifying its design. Perform valve with flat elastic membrane, which is made in the form of a disk, and install the membrane on the annular ledge in the area of the valve seat can simplify the design of the valve, to avoid complex molds for the manufacture of elastic membranes. Fixation of the membrane and the cover relative to the housing one locking nut allows you to easily assemble and disassemble if necessary the valve, such as valve repair. During production it is easy to control the quality of simple spatial structures. Execute mount bracket rack with glass and float on the valve cover allows you to create fully complete Autonomous valve design, which is easy to install in any available space is filled with a liquid capacity, for example on one of the fixed elements of the bottom drain valve, allowing the valve almost in containers with any supply to them a pipeline for supplying a liquid medium. As a consequence, the valve is assembled from simple parts can be quickly replaced, which allows you to create over the author in the operation of the device.

Figure 1 shows a longitudinal section of the described valve, figure 2 - type I in figure 1, figure 3 presents valve cover figure 4 - General view of the valve.

The valve includes a housing 1 with an inlet 2 and outlet 3 nozzles and a cylindrical saddle 4, the locking element 5, which interacts with the saddle 4, the Cup 6, is installed in the fill liquid containers. In the bottom of the Cup 6 is made of the hole, which has the float valve 7 for the message of the internal cavity 6 cups filled with a liquid capacity of the discharge of the last of the liquid, and a float 8, located on the possibility of vertical movement of the Cup 6. The inlet 2 of the housing 1 of the valve is indicated by a flexible tube 9 is installed in the wall filled the tank inlet 10 and the housing 1 of the valve is arranged to fasten to the bottom valve 11 of the descent of the liquid from the tank. Cylindrical seat 4 is made in the housing 1 with the formation around him annular cavity 12 provided with an inlet pipe 2. In the housing 1 at the level of the cut cylindrical seat 4 concentric with the most recently executed two annular ledge 13. The locking element 5 is made in the form of a flat elastic membrane (in the form of a disk), the diameter of which corresponds to a diameter greater degree annular ledge 13. Elastic flat membrane arranged in the housing 1 on the us the UE 13. On the membrane in the area of interaction with the seat 4 on the back relative to the seat 4 side of the fixed membrane sleeve 14. In larger diameter steps annular ledge 13 is installed, the cover 15 is made in her bottom jutting out of the nozzle 16 and the outer side wall of the cylindrical flange 17. On the outer side surface of the housing 1 concentric with the seat 4 made the thread. Elastic flat membrane is tightly pressed on the periphery of the ledge 13 of larger diameter of the housing 1 cover 15 by means of a cap nut 18 mounted on the cover 15 with an emphasis in the cylindrical flange 17 and is screwed on the thread of the housing 1. Through flexible flat membrane cavity cover 15 is separated from the annular cavity 12 of the housing 1, the cavity of the cover 15 is communicated through the nozzle 16 with the surrounding valve space and through the opening 19 in the membrane and the membrane of the sleeve 14 with the annular cavity 12 of the housing 1. The cover 15 is made with two brackets 20, 21, in this case through one of the brackets 20 can be rotated relative to the cover 15 is fixed to the lever 22, one end of which is equipped with a valve 23 with the possibility of overlapping the last nozzle 16 of the cover 15 and the other end of the lever 22 is kinematically connected with a thrust 24, on which are fixed the float 8 to move relative to the thrust 24, and by means of another bracket 21 Nachricht 15 fixed short side l-shaped strut 25, vertical long side of which is made with a saw-tooth comb 26, on its lateral surface and on the side of the yoke 25 has a glass 6. On the glass 6 along its side wall made of rectangular cross-section channel 27, on the wall which made the speaker inside the channel, spike, and hour 25 filtered through a channel 27 can travel cups 6 relative to the rack 25 and by means of a stud 28, which interacts with the saw-tooth comb 26, fixation of the Cup 6 relative to the rack 25.

The valve operates as follows.

In the initial position, when filled with liquid, such as water, the tank is empty, the float 8 is in its lower position in the Cup 6, the arm 22 presses the valve 23 to the nozzle 16 and the cavity of the cover 15 through the nozzle 16 is communicated with the outside of the valve space. In the flat elastic membrane is not pressed against the seat 4 of the housing 1. The saddle 4 is open for admission of fluid to fill it to capacity (not shown). On the inlet pipe 2 liquid through the saddle 4 enters the annular cavity 12 and further through the output pipe 3 enters the filled fluid container. As the filling capacity increases the level of the liquid and when the liquid reaches the float valve 7 of the latter rises and closes off the hole in the bottom of the Cup 6. Upon reaching the LM is the bone of the upper edge of the Cup 6, the liquid begins to fill the Cup 6. As a result, the float 8 is beginning to emerge that calls through rod 24 of the lever 22. Last, turning relative to the cover 15 covers the nozzle 16 valve 23. As a result, the liquid from the inlet pipe 2 through the annular cavity 12 and the hole 19 in flat elastic membrane enters the cavity of the cover 15, the pressure on the membrane sleeve 14 and through to the membrane 5 on the reverse side, which causes the movement of the membrane 5 to the side of the seat 4 and the membrane gradually, as the buoyancy of the float 8 is moved toward the seat 4 and eventually blocks the exit seat 4 liquid filled in the container.

When emptying the liquid from the Cup 6 merges through a hole in the bottom of the Cup 6, which is equipped with a float valve 7. The float 8 is lowered, which causes reverse rotation of the lever 22 to its original position. As a consequence of rotation of the lever 22, the valve 23 moves away from the nozzle 16, opening it. As a result, the pressure in cavity cover plate 15 decreases the pressure of the fluid in the inlet pipe 2 and under its own force of elasticity of the elastic membrane otlavlivatsya from seat 4, freeing the passage for the liquid. The filling capacity of the liquid is repeated, as described above.

The present invention can be used in the energy and utilities sector for the automatic is zapolneniya various types of containers, for example drain flushing toilets.

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.

EFFECT: increased reliability and easier operation of a filling float-valve.

FIELD: construction.

SUBSTANCE: support structure passes along the axis and includes a vessel. The valve body has a gate interacting with a moistureproof seat, and is arranged with the possibility of displacement around the axis. The upper and lower floats are arranged at various heights along the axis and interact with the valve body. The floats are arranged as movable independently on each other relative to the valve body together with variations of water level inside the vessel for selective and independent engagement with the valve body at various heights along the axis. The first and second control buttons impact a control lever. The control lever is attached to the valve body to lift the valve body along the axis. The buttons are arranged with the possibility of displacement at according various lengths along the axis, in order to lift the valve body at according various heights and to drain according amounts of water. The first button is arranged with the possibility of displacement to the first specified length in order to lift the valve body into the position of a partial drain. In position of the partial drain the valve body is only engaged with the upper float, besides, the lower float is not engaged with the valve body. The second button is arranged with the possibility of displacement to the second specified length, which is more than the first length, in order to lift the valve body in position of a full drain, where the valve body is engaged with the lower float.

EFFECT: increased efficiency of device operation.
