Valve for liquid

 

(57) Abstract:

The invention is intended to drain water from the tank, such as the flush-water tank of the toilet. The valve contains installed on the discharge pipe of the siphon and the drive element. The siphon is made in the form of the outer Cup. The latter is connected by its bottom with a driving element and its open side facing the drain pipe. In the outer glass with a gap in its perimeter installed protruding from the open end of the sleeve. The sleeve is made in the form of two coaxially arranged cylindrical shells. Shells are tightly interconnected in the upper part with the formation of the annular cavity. Coaxially drain pipe at the bottom of the tank has an inner cylindrical Cup with a Central opening in the base to connect the glass to the drain pipe. The inner Cup is turned to its open end to the outer glass. Its side wall is placed in the annular cavity of the sleeve. The drive element is made tubular for the message of the internal cavity of the outer Cup with the atmosphere through a hole in its bottom. This embodiment can improve the reliability of the valve over a long period of time without leakage. 4 C.p. f-crystals, 2 Il.

Known valve for a flush tank of a toilet bowl mounted on the supply pipe and closed by water pressure, comprising a housing, the seal with the rod that interacts with the lever at the opposite end of which is fixed to the float, the valve body is formed is made with a perforated bottom Luggage skip through it a rod, the upper end of which by means of sealing gaskets that interacts with the protrusion made on the inner surface of the casing eccentric to the axis of the rod (see USSR author's certificate N 236356).

This valve does not allow for a reliable and long-term work, as gasket from frequent interaction with the tab body loses its working qualities and needs to be replaced, otherwise the inevitable useless leakage of fluid.

The closest analogue to the claimed invention relates valve to the toilet tank of a toilet bowl containing mounted on the supply pipe and communicating with the lever at the opposite end of which is placed a float located in the additional empona, installed on the drain pipe and having a closing element (see USSR author's certificate N 382798).

This valve though and contains a siphon, but its design that requires a locking element, it is not possible to ensure reliable operation over an extended period of operation, because the locking element from frequent interaction with the protrusion made on the return pipe, loses its working properties and requires replacement, it is possible and the destruction of the ledge that leads to the useless leakage of liquid from the tank of the toilet.

The objective of the invention is to provide a valve that provides reliable operation over a long period of time and does not require frequent replacement of the sealing valve element and eliminating useless diversion.

These technical results are achieved due to the fact that the locking element siphon performed on the drain pipe is the air tube formed at work. The siphon is made in the form of external Cup connected to its bottom with a driving element and facing the open end to the drain pipe, the outer glass with a gap in its perimeter installed protruding from the open end of the sleeve, made in the form of frezowanie annular cavity, coaxially drain pipe at the bottom of the tank has an inner cylindrical Cup with a Central opening in the base to connect the glass to the drain pipe so that the inner Cup is turned with its open face to the outer Cup, and its side wall is placed in the annular cavity of the sleeve, and the drive element is made tubular for the message of the internal cavity of the outer Cup with the atmosphere through a hole in its bottom.

The invention is illustrated graphic material, where Fig. 1 shows a valve for the liquid in the closed position, and Fig. 2 presents its open position.

Valve for liquid, for example, to flush the tank 1 bowl contains the drain pipe 2, the drive element 3, the siphon, made in the form of the outer Cup 4 connected to its bottom with a drive element 3 and facing the open face to the drain pipe 2, in the outer Cup 4 with a gap along the perimeter installed protruding from the open end of the sleeve 5, containing two coaxial spaced ribs, tightly interconnected in the upper part with the formation of the annular cavity. Coaxial discharge pipe 2 at the bottom of the tank 1 has an inner cylindrical Cup 6 with a hole in DN is n the open end to the outer Cup 4, and the side wall of the inner Cup 6 placed in the annular cavity of the sleeve 5. The drive element 3 is made tubular, may be provided with a restrictor 7, made for example in the form of an annular protrusion and the guide sleeve 8, fixed in the housing or cover of the tank 1, while the inner cavity of the outer Cup 4 is communicated with the atmosphere through channel 9, the drive element 3 through the hole in its bottom. The diameter of the orifice channel 9 made from 8 to 10 mm, it is free of overlap any finger of the hand of man.

Square bore anywhere in the channel formed between the walls of the outer Cup 4 and the walls of the sleeve 5 made more of bore drain pipe 2. On the upper end of the drive element 3 can be performed diverter valve of any structure (Fig. not shown), and in the absence of the diverter valve, this end can be accomplished with a convex or concave surface, touch-friendly finger.

The outer Cup 4 to increase the buoyancy may be provided with a float body, made for example in the form of an open bottom cavity 11 formed by the l-shaped annular wall 10, garmet is executed by a material with positive buoyancy, for example, foam or tube.

Valve for fluid works as follows.

In the closed position when the container is, for example, the tank 1 bowl filled with a liquid delivery pipe (figures not shown), the outer Cup 4 with the sleeve 5 is located in the extreme upper position defined by the stopper 7 of the stroke of the drive element 3, the water cannot flow into the drain pipe 2, because this prevents air tube, formed in the annular cavity of the upper part of the sleeve 5. Should it be necessary to drain the fluid drive element 3 is fed down the sleeve 8 eliminates the bias, if this goes down the outer Cup 4 and rigidly connected with the sleeve 5, the liquid formed in the siphon channel between the walls of the outer Cup 4 and the walls of the sleeve 5 flows into the drain pipe 2. The provision of the cross-section area between the walls of the outer Cup 4 and the walls of the sleeve 5 more flow area of the drain pipe 2 allows to provide beschryvinge fluid flow. After draining the fluid during the filling of the tank 1 outer Cup 4 with the sleeve 5 spontaneously rise up, having positive buoyancy, breaking the siphon channel for the th upper part of the horizontal section with the formation of the open bottom of the annular cavity 11, filled with air or a material with positive buoyancy, such as foam or cork. The lack of sealing elements helps to ensure reliable operation of the valve, eliminating the possibility of leakage of liquid from the tank 1. The presence of the channel 9 in the tubular drive element 3 allows at any time to break the siphon canal that provides water savings. In the upper part of the driving element 3 may be mounted diverter valve of any structure (Fig. not shown), which will allow a more reliable and convenient operation of the valve. Guide sleeve 8 is made of antifriction material (with the lowest coefficient of friction, for example PTFE), which avoids jamming of the drive element 3.

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.
