Description

The invention relates to sanitary equipment, namely to flushing tanks of sanitary appliances used to flush toilets and floor bowls.

A device is known for dosing filling flush tanks with a delay in opening the supply valve almost until the filling tank is empty. - The possibility of such a delay is very advisable, since the entire additional volume of water entering through the supply valve is used with very low drainage coefficient of performance, in relation to the efficiency of flushing. Therefore, the ability to keep the supply valve closed for the period of descent allows using the practically expended amount of water for flushing more efficiently. To achieve this goal, according to this device, in addition to the usual supply valve with a float controlling it through the lever, a latch is added that holds the supply valve lever from lowering when the water level in the barrel decreases and the chain of floaters connected to it follows the height of the level water and at the end of the descent, by tensioning the chain, releasing the lever from the delay latch.

The disadvantage of this device is the need to introduce additional links operating in a clutchless and clutchless mode of reliability, while significantly complicating the previously very simple design. The second drawback is the use of the outdated principle of controlling the supply valve, based on balancing the pressure force in the water supply network and the force brought to the valve by the displaced force of the displacement of the float, the principle in which the volume of the release dose depends on the pressure in the water supply network.

A device is also known for providing accelerated closing of the supply valve by delaying the float float up until the end of filling the tank to a predetermined volume. This is achieved by placing the float in a vertically movable container having a valve built into its bottom, which is at the same time a rigid stop, limiting simultaneously the ascent height of the container. Moreover, the tank is equipped with a toroidal float that keeps it afloat. Therefore, from the beginning of the moment of filling the tank

pops up at the same time as the water level rises and closes the valve. During further filling of the tank, it remains dry until then. until the water level reaches its edges, after which the process of its quick filling begins, as a result of which the float floats and closes the supply valve. The disadvantage of this solution, in addition to the impossibility of delaying the opening of the supply valve for the period of water discharge, is some uncertainty about the moment when the supply valve closes completely when its float in the tank emerges. This is because quite a lot of water is required to fill the entire volume of the container. As the tank is full, the valve starts to close accordingly, but there comes a moment when the tank is not yet completely filled, the float does not float fully and closes the inlet valve not tight enough, however, the flow of water has already been reduced so that the filling of the tank continues, but extremely slowly. In order to ensure complete closure of the valve in such a situation, a small hole is made in the wall of the container used in the prototype, which, even before the tank reaches the edge level, begins to pass a small amount of water. Since this amount is small, it does not have time to act on the float, but at the moment when the flow of water through the edges of the tank has almost ceased, water continues to flow through this hole, providing a slow but complete valve closure.

A device for controlling the supply valve of a flushing tank is known, comprising a bracket fixed to the flushing tank, a container with an opening in the bottom, overlapped by a spring-loaded valve and a float of the supply valve located in the container.

However, the known device is difficult to construct and requires an increase in volume when using the device to delay the opening of the supply valve during descent.

The aim of the invention is to increase the efficiency of the device by more quickly closing the supply valve and delaying its opening during the descent

This goal is achieved in that the control device for the supply valve of the flush tank, comprising a container fixed to the flush tank with a hole in the bottom, overlapped by a spring-loaded valve and

According to the invention, the float of the supply valve is equipped with a load and a throttle, by means of which the load is connected to a spring-loaded valve, the tank being pivotally mounted on an arm made with limiters of the tank rotation angle, and eccentric with respect to its center of gravity, the load is made of material whose density is equal to the density of water, and the spring is connected at one end to a container. The spring at the other end may be connected to the valve. The hinges of fastening the container to the bracket and the lever to the container can be placed on the same axis.

Figure 1 schematically shows the device in position when the tank is completely filled with water and the supply valve is closed; Fig. 2 shows a device at the moment of completion of the water drain, when there is very little water left to be drained in the tank; in Fig. 3 - the device at the moment of completion of filling the tank, when the water level has reached the edge of the tank and water from the supply valve goes to fill the bridge; Fig. 4 is an isometric view of a double joint having a common axis for securing the container to the bracket and a lever to the container; figure 5 - a device with direct mounting klzpan to a spring embedded in a container.

The control device for the supply valve of the flushing tank contains a housing 1, a bracket 2 mounted on it, carrying a tank 4 on a double hinge 3, with a float 5 of a supply valve 6 connected to it by a lever 7. The bracket is equipped with limiters 8 and 9 of the tank rotation angle on its hinge mounts. An opening 10 is made in the bottom of the container, to the edges of which a valve disc 11 is attached, which is loosely fixed to the end of the lever 12. The lever 12, pivotally mounted on the container, is also connected with a spring 13, which creates the force necessary not only to prevent water from entering the inside capacity, but also the force sufficient to hold water in the container filled with it, this is necessary to keep the supply valve closed even after the water level during descent is below the capacity. Clinically coupled to the valve 22 via a link 14, pivotally or flexible thread, a load 15 made of a material with a density of the order of unity. A vessel filled with water can also be used as such a load. Such a density is necessary so that, being surrounded by water, the load, as it were, loses its weight and cannot affect

The edges of the container are formed by a slice of their inclined plane; when filling the container, it will overflow over the lower part of the edge, indicated by 5 at 16. If the container is round, cylindrical, which is not necessary, the cross section of the jet passing through the edge section JTOT takes segment shape. Position 17 denotes the height of the water level in

0 considered moment of the cycle of the device. The spring 13 can be used in other forms of execution. So, in Fig. 4, the position 18 shows its execution, working on twisting, as in the linen

5, the Ego clip allows it to be compactly placed on the common axis 19 of the double-hinged receptacle of the container and the valve lever. The ends of the spring associated with the container and the valve lever are indicated by the numbers 0 and 20 and 1. The position 22 (see Fig. 5) is indicated by the same spring is placed inside the container. Such a simplification (however, is not always justified because it requires some increase in the height of the container.

In the position shown in fmg.1, the device is in place until there is a night trigger, the trigger release button, 0 r ,,, i. C -.-) the level of the hearth will start to drop rapidly One time, the device will cool down in the same position, keeping the supply valve closed even after the water level falls below the tank valve, since the spring 13 prevents the hydrostatic pressure of the water in in the tank. But when the water level decreases so much that cargo 15 is in the air, it will overcome its weight

0 the spring resistance will open the valve, it will flow out of the tank, allowing the float to lower and open the power valve. Thus, the water doesn’t enter the tank when its descent

5 is almost finished, and the remnants of a given dose flow from the tank. During the HSRGO described pepiotsa capacity will maintain its inclined position, leaning on the limiter of its rotation 9. After closing

0 exhaust valve, the tank filling process begins again. When the load 15 is covered by water and the influence of its weight is not - trapezoidal, the valve of the tank closes (see Fig. 3) and then, surrounding the tank, the water is no longer

5 will be able to get inside. Since the container remains empty, its pushing force will rotate the container on the hinge A, now pressing it against the limiter 8 of its rotation angle. Thus, the container is squeezed upright until the f-i "vpupe of water reaches its edge 16, which will be in a precisely fixed hard stop position, accurately determining the height of the level of filling of the tank, since water, after reaching the edge, will enter the tank. The float of the tank will begin to float, more and more blocking the supply valve and the debit of water entering the tank will decrease more and more, and the filling of the tank becomes significantly slowed down. However, in this case, this deceleration can be avoided, since the buoyancy force decreases proportionally to the filling of the tank, the edge 16 begins to lower, allowing the tank to scoop up the water that has already filled the tank, the buoyancy force of the tank completely disappears, and the edge of the tank rests on the stop 9. holding it fully filled in an inclined position. The supply valve is completely closed, the device will return to the initial position shown in Fig. 1.

The required amount of pressing force developed by the spring is largely determined by the size and shape of the bottom opening of the container. So, if a nozzle shape is added to the edges of the hole, increasing the rate of water outflow from the container, the diameter of the hole can be reduced and the spring force accordingly reduced. Technological factors are also important, if the dispersion of the set values of elasticity will fit into the tolerance of the order of 20%, then the coefficient of exceeding the spring force by the hydrostatic pressure on the valve will be of the order of 1.2-1.25

The technical and economic efficiency of the device is very high. Reliability and service life of a standard supply valve are significantly increased, since it creates an optimal operating mode, quick shutdown with a pressure that is in any way higher than the pressure in the water supply network, and, as a result, the complete absence of erosion wear of the seal. Reliability is also enhanced by the complete absence of mating and disengaging elements that work with mutual slippage and are therefore at risk of seizing from clogging by rust particles entering the water. The device provides reliable operation both in newly manufactured tanks and in the modernization of existing flushing tanks. The cases of standard domestic tanks are already equipped with an opening in the housing on which the bracket of the proposed device should be installed. Intended for another purpose - to provide water supply both on the right and on the left side of the tank, however, from these two openings it always remains empty and can now be used.
