Description

The utility model relates to flushing devices with tanks, in particular, to exhaust valves for a flushing tank, and is intended to provide water for draining into the toilet from a sanitary tank with two flush volume options: economical (small flush) mode and full flush mode, while the volumes of water entering the flush in these modes can be regulated.

A tank flush valve is known in the art in which the outlet valve of the flexible closure element at the end of the tubular element rises from the seat by a button that is connected to the tubular element using levers and a link so that the element moves a certain distance using the button. The tubular element is held in the upper position by means of a vacuum created in it by the flow around the lower end and the closure cap of the upper end. The float is connected to the tubular element and moves in the float chamber (GB 1510419, 05/10/1978).

A flushing device is known, formed by a drain valve and a control tank with a float equipped with a control device for selecting full or partial discharge of the flushing tank. The valve is connected to the tank, the float installed in it, and covers the control pipe with the camera and a flat contact rib. The tank is equipped on its circumference with holes with a stop abutting against the lower edges. The lever fork is rotatable and mounted on the limiter. The fork lever interacts with the float gripper mechanism. The upper end of the control pipe is rigidly fixed on one side of the drive pulley, the other end of which is connected to the swing arm (SK 157199, 11.06.2011).

Known drain valve containing fixed in the bottom of the tank seat, mounted on the saddle cup and overflow unit. The latter includes an axially movable pipe. On the outer surface of the pipe, a float placed in the glass is strengthened. A locking element is installed at the lower end of the pipe. The overflow unit pipe is skipped with the possibility of axial movement through the glass. The overflow unit is kinematically connected with the rod of the lifting handle of the locking element. The glass is mounted on the saddle by means of a bayonet fitting. The overflow assembly further comprises an inner pipe. The latter is partially located inside the overflow assembly pipe. The inner pipe is installed with the possibility of axial movement and subsequent fixation of its position relative to the pipe of the overflow unit by means of a union nut and gasket. The latter is clamped with a union nut between the pipes of the overflow assembly. Two diametrically oppositely located brackets are made on the overflow assembly pipe from the side of its upper end. In each of the brackets, a rod is fixed on the lower end side. The upper end of the rods is fixed in the bracket. A longitudinal section is made at the free end of the stem with the formation of at least two cantilevered elastic lobes. Each of the petals on the outside is made in the form of a stop expanding upwards. The bracket is put on the rod through the stops on the elastic petals of the stem with the possibility of the impact of the stops on the bracket when lifting the handle of the rod of the shut-off element of the drain valve (RU 2248488, 03.20.2005).

Known water outlet valve for toilet flushing barrel, consisting of a base, the base of the water discharge buttons, mounted on the hypsometric axis, regulatory means. In the center of the base is a pipe. Regulatory tools allow horizontal and lateral regulation of the track at the heart of the water discharge buttons; the connection of the preceding track, the adjusting means for the axis, makes it easier to disconnect the whole base of the unloading selection buttons so that the outgoing pipe can be removed and the sealing elastic ring replaced. Two floats allow you to make a choice of the water quantity discharged to the toilet of the flushing barrel, making savings in water (GR 1005325, 10/18/2006).

The disadvantages of this design is the unreliability in the operation of the following elements: springs in the push-button assembly of the exhaust valve; connecting the lever to the rod and bracket; traction connection with a lever.

The problem to which the proposed utility model is directed is to create an exhaust valve for the flush tank, which would eliminate the above disadvantages.

The technical result achieved by the implementation of this utility model is to increase the reliability of the valve by adjusting the position of the overflow pipe in height, which ensures the correct operation of the valve at a given water level in the tank, and the possibility of moving the button assembly in the rack in two mutually perpendicular directions, which compensates misalignment of openings in a tank and a cover.

The specified technical result is achieved in the outlet valve for the flushing tank, containing a push-button assembly interacting with a guide sleeve, which is connected through a transitional sleeve to a frame pivotally connected to the rod and mounted for rotation in racks on which a glass is fixed, inside which there is a small float the flush and the float of the full flush and connected to the saddle, the opening of which is made with the possibility of opening / closing by a bottom valve fixed in the overflow housing, in which The overflow pipe connected to the draft was installed and connected to it by means of a locking device.

The button assembly consists of a housing in which a full flush button and a small flush button are placed, made on a leg and in contact with a spring resting against a support washer.

The overflow housing together with the bottom valve and overflow pipe is made with the possibility of vertical reciprocating motion.

The rod is made in the form of a rack with teeth.

The frame is a diverse lever.

The essence of the utility model is illustrated by the drawing, which shows a General view of the exhaust valve for the flush barrel.

The exhaust valve for the flush tank contains a push-button assembly that interacts with a guide sleeve 12, which is connected through a transitional sleeve 13 to a frame 10 (represents a different arm), pivotally connected to a rod 11 and mounted to rotate in the uprights 3.

A glass 1 is fixed on the racks 3, inside of which a small flush float 6 and a complete flush float 7 are located.

The glass 1 is connected to the saddle 2, the opening of which is made with the possibility of opening / closing by the bottom valve 15, fixed in the overflow housing 4 by means of the washer 14. On the glass 1, on its outer side, there is a shutter 9 with the possibility of vertical reciprocating movement.

The seat 2 is fixed to the bottom of the flushing barrel by means of a nut 23. The seal of the gap between the seat 2 and the nut 23 is provided by a seal 24.

In the overflow housing 4, it is coaxially mounted and connected to it by means of a locking device 8 (lock) overflow pipe 5, connected to the rod 11, made in the form of a rail with teeth. The seal of the gap between the overflow housing 4 and the overflow pipe 5 is provided by a sealing ring 16. The overflow housing 4 together with the bottom valve 15 and the overflow pipe 5 is configured to vertically reciprocate with respect to the body of the flush barrel over the rod 11.

The button assembly consists of a housing 22, in which a full flush button 18 and a small flush button 19 are placed. The buttons 18, 19 are made on the leg 23 and are in contact with the spring 17 resting against the supporting washer 22.

Opening the bottom valve located on the overflow housing is carried out by means of a lever system, structurally implemented by a button leg, adapter sleeve and a frame. A thrust is fixed to the frame, which in turn is connected to an overflow pipe. The overflow pipe is coaxially mounted and connected to the overflow housing using a special locking device. Using the same device, the overflow pipe can be adjusted in height to ensure correct operation of the valve at a given water level in the tank.

When you press the complete flush button through the lever system described above, the overflow body moves up along with the bottom valve and overflow pipe and opens a hole for draining water in the saddle. When you press the button full flush to the stop, the maximum possible movement of the overflow housing. To ensure draining when removing the force from the button, the required volume of water and preventing premature closing of the bottom valve is a large flush float, which is installed by its axes in the holes of the glass and has in its design protrusions. When water is drawn into the tank, the float rotates on its axes to the stop in the overflow housing, on which protrusions are also made in a certain place. When the overflow housing is moved, its overhangs extend above the overhangs on the complete flush float, which ensures that the overflow housing with the overflow pipe is held in open position until water spills from the glass. With a decrease in the water level in the glass, the lifting force that holds the glass disappears; due to the displaced center of gravity, it goes into a different position, while releasing the overflow housing. The overflow casing is lowered together with the bottom valve and stops draining the water. Water from the glass leaves slowly due to the gap between the glass and the overflow housing and due to the window in the glass, which is closed by a shutter. By moving the flap to change the window section, the volume of complete flushing is regulated.

When the small flush button is pressed all the way over, the overflow casing together with the overflow pipe is less than when completely washed out and occurs until the overflow cams protrude into the large flush protrusions. When the effort is removed from the small flush button, the overflow pipe with the casing and the bottom valve is held in this position by the small flush float 6. The lifting force of the small flush float is not enough to go through the stops on the overflow casing, but enough to hold it. In this raised position, the pipe body remains until the lifting force of the small flush float disappears due to a decrease in the water level in the tank. This moment and, accordingly, the volume of small flush water is regulated by the movement of the small flush float along the guides relative to the overflow casing with fixation using a locking device.

The main distinguishing features of the valve are:

- the availability of adjustments to the volume of water full and small flush;

- the ability to move the button assembly in the rack in two mutually perpendicular directions to compensate for misalignment of the holes in the tank and the lid;

- the presence of a spring in the button assembly to ensure the return of the buttons to their original position;

- small dimensions of the upper part of the valve, allowing you to place it in tanks, in which the hole in the lid is placed close to the edge;

- ease of height adjustment of the overflow pipe, allowing it to be carried out without removing the valve from the tank;

- design features of the valve and thrust allows the use of thrust of the same size regardless of the valve height setting.
