Valve for liquid

 

(57) Abstract:

Valve for fluid refers to sanitary engineering and can be used in a drain tank of a toilet. The valve contains a siphon and the drive element 3. The siphon is made in the form of the outer Cup 4, the bottom of which is connected with a drive element 3 and the open end facing to the drain pipe 2. In the outer Cup 4 with a gap along the perimeter of the installed protruding from its open end sleeve 5 made in the form of two coaxially arranged cylindrical shells connected 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 6 with a Central opening in the base to connect the glass to the drain pipe. The internal glass 6 is turned to its open end to the outer Cup 4, and its side wall is placed in the annular cavity of the sleeve. The invention improves the reliability. 4 C.p. f-crystals, 4 Il.

The invention relates to the field of hydraulics, in particular for sanitary equipment, such as valves for flush tank of the toilet, i.e., may be used where required to ensure long and reliable operation of the valve.

water includes case, the seal with the rod that interacts with the lever at the opposite end of which strengthened 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 interacts with the protrusion made on the inner surface of the casing eccentric to the axis of the shaft [1].

This valve does not allow for a reliable and long-term work, because the gasket from frequent interaction with the tab body loses its working properties and requires replacement, otherwise there are useless leakage of fluid.

The closest analogue to the claimed invention is a 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 capacity is moveable in a vertical plane. Additional capacity is also mounted branch of the siphon installed on the drain pipe and having a locking element [2].

This valve, although contains a siphon, but its design is of erida 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 of the valve over a long period of time and does not require frequent replacement of the sealing valve element and eliminating useless leakage of fluid.

This technical result is 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 the outer Cup, the bottom of which is connected with a driving element, and its open end facing 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 two coaxially arranged cylindrical shells connected in the upper part with the formation of the annular cavity coaxial drain pipe at the bottom of the tank has an inner cylindrical Cup with a Central hole in the bottom for connecting the Cup with a spout trusina in the annular cavity of the sleeve, moreover, the inner Cup can be fitted with additional side wall connected to the bottom of the Cup and placed between the outer shell of the sleeve and the side wall of the outer Cup.

In Fig. 1 shows a valve for liquids in closed position; Fig. 2 - valve in the open position; Fig. 3 - valve for liquids with internal glass with dual-side wall in the closed position; Fig. 4 - this valve in the open position.

Valve for liquid, for example, to flush the tank 1 bowl contains the drain pipe 2, the drive element 3, the siphon is made in the form of the outer Cup 4, the bottom of which is connected with a drive element 3 and the open end facing to the drain pipe 2, in the outer Cup 4 with a gap along the perimeter installed protruding from the open end of the outer Cup 4 sleeve 5 made in the form of two coaxially arranged cylindrical shells connected 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 Central opening in the base for connection of the Cup 6 with the drain pipe 2, while the inner glass 6 is turned to its open end to the outer one hundred is niceley side wall, connected to the bottom of the Cup 6 and is placed between the outer shell of the bushing 5 and the side wall of the outer Cup 4.

In addition, the valve is provided with a guide sleeve 8 that is installed in the lid of the tank 1, and the drive element 3 is designed in the form of a rod or tube, passed through the guide sleeve 8 with free vertical movement, for example by performing a guaranteed backlash and application of anti-friction coatings. The drive element 3 provided with a limiter 7 turn. The output end of the drain pipe 2 is made with an internal annular ledge 9, and the sleeve 5 is installed in the outer glass of restriction on movement in the horizontal direction, for example, by means of plates or pins attached to the shells of the sleeve 5 or to the walls of the cups 4, 6 or drain pipe 2, and the square of flow sections of channel drain pipe 2 and the clearance between the sleeve 5 and the outer Cup 4 in their most narrow places made similar in size and smaller in at least two times than the area of the bore annulus, formed between the outer wall of the Cup 4 and the outer wall of the inner Cup 6. Perhaps instead of the inner Cup 4 with two side St the bottom.

The valve operates as follows.

In the closed position when the tank such as the tank 1 bowl filled with liquid delivery pipe (Fig. not shown), the outer Cup 4 with the sleeve 5 is located in the extreme upper position, which can be determined by the focus limiter 7 progress drive element 3 in the guide sleeve 8, 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 guide sleeve 8 eliminates the bias, if this goes down the outer Cup 4 and connected with it by means of, for example, plates of the sleeve 5. The sleeve 5 and the outer Cup 4 can be rigidly connected with each other or with the possibility of contact due to the action of the buoyancy force. The liquid formed in the siphon channel between the walls of the outer Cup 4 and the outer shell of the sleeve 5 or the outer wall of the inner Cup 6 flows into the drain pipe 2. Ensuring exceeding two times the area of the annular flow cross-section between the outer wall of the Cup 4 and the outer wall vnutrennego glass 4 in their most narrow places allows you to provide beschryvinge fluid flow.

After draining the fluid and during the filling of the tank 1 outer Cup 4 and the sleeve 5 spontaneously rise up, having positive buoyancy, breaking the siphon channel. The presence of internal ledge 9 of the drain pipe 2 and the protrusion of the shells of the sleeve 5 from the open end of the outer Cup 4 provide reliable charging the siphon.

By adjusting the weight of the drive element 3, by performing it in the form of a rod or tube and adjusting the weight of the outer Cup 4 and the sleeve 5, by changing the thickness of the walls and shells, it is possible to achieve the required height of lift.

The lack of sealing elements helps to ensure reliable operation of the valve, eliminating the possibility of unintended leakage of liquid from the tank 1.

The drive element 3 may be connected with the upper part of the sleeve 5, by removing the outer Cup 4, while draining water from the tank 1 will be determined by the height of the input end of the drain pipe 2, which can be performed at the level of the bottom of the receptacle 1.
