Description

The device is designed for the selection of high-pressure water from the water supply system and the delivery of water with low pressure, the required flow rate and can be used in industry, cleaning systems, geotechnology.

It is known “A hydraulic device for filling and closing a toilet tank” EP 0251837 [1], which contains a valve that opens under the action of the weight of the movable container filled with water.

The disadvantages of the known designs are the increased complexity of the device.

Closest to the claimed technical solution is the “Ball valve regulator” WO 9821512 [2], which includes a valve connected to the water supply pipe, a filling tank, a mechanism for transferring the weight of the tank to the valve, a device for draining water.

The known device is relatively simple.

A disadvantage of the known construction is the high dimensions and insufficient force developed by the float acting on the rod connected to the valve. Also, the device has a low reliability of locking with increasing pressure in the supply pipe.

The technical result of the proposed utility model is to reduce the size and weight of the device with increasing force applied to the valve, as well as increased reliability.

The technical result is achieved by the fact that a water flow regulation device containing a valve connected to a water supply pipe, a (filled) tank, a mechanism for transferring the weight of the tank to the valve, a device for draining water is characterized in that the mechanism for transferring the weight of the tank to the valve is designed that the weight of the water filling the tank causes the valve to close.

The valve may be a movable platform connected to the movable part of the tank, located opposite the seat, a stationary opening at the end of the supply pipe, the direction of movement of the movable platform essentially perpendicular to the plane of the opening. The movable platform, as a rule, has a plastic surface facing the valve seat. The specified implementation of the valve allows to simplify the design.

The tank at one end can be connected to the hinge, the valve is connected directly to the tank, at a distance from the hinge. The tank can also be mounted on a hinge by means of a bracket. The distance from the axis to the point of attachment of the valve (or valve actuator) determines the amount of force transmitted from the tank and water to the valve, and is selected as needed.

 The tank at one end can be connected with a hinge, the valve weight transfer device is a lever mechanism with a fixed lever axis, one arm of which is mechanically attached to the thrust connected to the tank, and the other part is connected to the movable part of the valve. The lever mechanism will facilitate the adjustment due to a simple change in the ratio of the length of the arms of the mechanism.

Water can be drained from the tank with a water flow regulator connected to the bottom of the tank. A tap, calibrated bushing, etc. can be used as a water flow regulator.

The device may further comprise a tank weight compensation device, for example, a counterweight or a spring. The device for compensating the weight of the tank will allow you to adjust the filling of the tank with low water pressure in the supply pipe, to avoid a situation where the weight of an empty tank prevents its filling.

The device may further comprise a device for preventing wave-like movement of water in the tank, for example, partitions, porous filler, etc. The undulating movement in the tank can lead to instability in the operation of both the supply pipe and the consumable part of the device.

FIG. 1 shows an embodiment of a device with a lever mechanism; FIG. 2 with the valve actuator on the side wall of the tank; and FIG. 3 option with the placement of the valve on the bottom of the tank, where:

1 - tank mounting axis;

2 - water flow regulator;

3 - valve;

4 - tank wall;

5 - tank bottom;

6 - water level;

7 - water supply pipe;

8 - the direction of movement of the tank;

9 - lever with stationary axis;

10 - thrust lever.

The device operates as follows: the tank, consisting of the walls of the tank 4 and the bottom of the tank 5, is fixed to the stationary axis 1. The tank is filled from the water supply pipe 7 by means of the valve 3. Water flows from the tank through the water flow regulator 2. The water level in the tank is shown . 6. The direction of movement of the tank 8 (around the stationary axis 1). For the variant with lever 9, one shoulder is connected to the valve, the other is connected to the tank through the pull of the lever 10.

The throttling valve is located in the tank and is connected to the water supply, from which high pressure water flows. The tank is fixed on the axis and has the ability to move around the circle up, down from the horizontal position. A throttling valve is attached to the tank body in such a way that when the water level in the tank rises, the locking force on the valve increases, which leads to a decrease in water consumption and vice versa.

At the bottom of the tank there is a drain hole with a water flow regulator through which water is drained under the pressure of the water level in the tank.

Reducing the flow of water through the flow regulator leads to an increase in the water level in the tank and an increase in the locking force on the valve, which leads to equalization of the flow of water through the water flow regulator and the throttling valve.

With an increase in water flow through the water flow regulator, the water level in the tank decreases and the locking force on the valve decreases, which leads to equalization of the water flow through the water flow regulator and the throttling valve.

For the embodiment of FIG. one:

The valve is mounted on the lever. The lever is swinging on the axle. The valve seat, the lever shaft and the tank mounting shaft are fixed on a common base. The lever, on the opposite side of the valve, is attached to the bottom of the tank. A higher water level in the tank creates a greater locking force on the valve.

For the embodiment of FIG. 2:

The valve is installed on the side wall of the tank from the side of the tank to the axis.

The valve seat and tank mounting axle are fixed on a common base. The water level in the tank acts on the valve in the same way.

For the embodiment of FIG. 3:

The valve is mounted on the rack to the bottom of the tank working surface down. Valve seat down from below. The valve seat and tank mounting axle are fixed on a common base. The water level in the tank acts on the valve in the same way.

The technical result is a reduction in size and weight of the device while increasing the force applied to the valve is achieved by using the weight of all the liquid in the tank to form the force. Increased reliability is achieved by simplifying the device.

Industrial application. The claimed device can be successfully used to ensure a stable water level in the tank and to ensure a stable water flow.
