A drain valve

 

(57) Abstract:

A drain valve relates to sanitary devices, in particular used in flush tanks. The device includes a valve in the form of an open bellows, a rod with a shutter button, located above the bellows bracket for stem and seat flush tube. The bracket is connected with the rod threaded mount for height adjustment of the upper edge of the bellows relative to the liquid level in the tank, and a bellows made of metal, rubber or plastic. The technical result from the use of the device is the elimination of leakage and increased durability. 2 Il.

The invention relates to hydraulic devices and is mainly used in sanitary appliances.

Known self-latching valve flush tank with direct Association to the toilet ("CD"), comprising: a housing, a rubber drain valve (pear), overflow pipe, a lever and shutter release button. (See Fomin, B. Fomin and Y. Plumbing in your apartment. M:Mark, 1994, S. 60-67).

However, the rubber drain valve does not provide a tight seal after discharge due to ingress of rust, postero what causes them.

The closest known analogue, Toilet flush tank (CH, patent N 397552, class E 03 D 1/30, 1996), which has the following characteristics: the valve is in an open bellows, a rod with a shutter button which is located above the bellows bracket for the rod, and saddle flush tube.

However, in a decision there was no adjustment of the upper edge of the bellows relative to the liquid level in the vessel, as well as the implementation of the bellows was only made of plastic or rubber, which did not ensure the integrity and reduced service life of the valve.

The objective of the claimed invention was to increase the durability of the drain valve.

The essential features of the invention are: the bracket is connected with the rod threaded mount; for use of the bellows, metal, or rubber or plastic.

The technical result from the use of the device is as follows: the height adjustment of the upper edge of the bellows relative to the liquid level in the tank; except for leakage through the valve during normal filling tank; the improvement of the durability of the discharge valve; a spring properties of the metal bellows are used to return drain valve.

In Fig. 1 shows susno the definition bellows and flange mounted to the vessel.

A drain valve (Fig. 1) consists of a container 1 and cover 2, which are interconnected by the fastener 3. In the lower part of the vessel 1 is fixed saddle flush tube 4, which is tightly worn corrugated rubber tube (bellows) 5 thickness of 2-4 mm

The bellows may have a cylindrical or conical shape and works in compression. The corrugations of the bellows can be horizontal or screw. Rubber corrugated tube (bellows) may have an internal skeleton of the cord, which creates sufficient resistance to lateral bending under compression.

In the upper part of the outdoor bellows 5 is fixed to the pipe 6 and the bracket 7 on it. Reliability hermetic mounting can be improved by using HomeDialog mounting on both nipples. The upper part of the bracket 7 includes a threaded hole which is screwed the stem 8 and the position it is secured by a nut 9. The threaded portion of the rod 8 serves to adjust the height of the upper edge of the bellows 5 relative to the height level of the liquid in the tank 1.

To limit the movement of the rod 8 upwards, the rod 8 has a stepped shape, and to mitigate the shock rod 8 carries the pad 10. In the upper part of the shaft 8 is mounted a spring 11, running on with the cuttings (bellows) 5 stainless steel brass or bronze, so here applied flange fastening 13 of the bellows 5 to the tank 1, and in the upper part of the bellows 5 is welded to the bracket 7.

The principle of operation of a discharge valve is as follows. The tank 1 is filled with liquid (water), for example from the float valve to the staffing level at which the liquid can flow into the bellows 5 and the seat is flush tube 4.

To drain the fluid you need to press the hand on the shutter button 12, which acts on the rod 8, which compresses the spring 11 (or corrugations 5) moves the bracket 7 and compresses the corrugations of the bellows 5. Formed in the cavity between the bracket 7 and the top slice of the bellows 5 directs the fluid that passes through the cavity of the bellows 5 and out of the saddle flush tube 4. If you change the height of the level in the tank, and is regulated by the height of the upper edge of the bellows 5 by a nut 9.

After removing the load from the shutter-release button 12, the spring 11 (or metal bellows 5) returns the rod 8, the bracket 7 and the bellows 5 in the original upper position, when the upper edge of the bellows 5 stops the flow of fluid. To soften the hard blow of the rod 8 when lifting upward on the rod and a rubber gasket 10.

When there is a malfunction in the float bone 1 and the emergency exit of liquid through the internal cavity of the bellows 5 and the seat is flush tube 4.

A drain valve including a valve in the form of an open bellows, a rod with a shutter button which is located above the bellows bracket for stem and seat flush tube, characterized in that the bracket is connected with the rod threaded mount for height adjustment of the upper edge of the bellows relative to the liquid level in the tank, and a bellows made of metal, or rubber, or plastic.

FIELD: machine building.

SUBSTANCE: present invention pertains to hydro-automation, particularly to hydraulic inlet valves with dosed supply of liquid into a filling tank, and is meant for use in systems for filling different types of reservoir with water. The filling float-valve has housing with an inlet, an outlet opening and a seat inside the housing in form of a nozzle, a gate opposite the seat, in form of an elastic membrane with thickening in the area where it is in contact with the seat. The axially moveable coupling of the gate is on an arm support. The arm support is fixed against the housing using a cap nut and is kinematically linked to the float through a lever and a tie-rod. The float is fitted with provision for vertical displacement. 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.
