Abstract

The utility model relates to a water volume adjustable self-closing valve for flushing a toilet, which is composed of a main valve body, a floating valve body, a pressure releasing valve, a bent arm, a sealing rubber ring, a limiting device, an adjusting screw, a sealing gland for the main valve body, etc. When maximal water discharging flow capacity can be kept under water source with various kinds of pressure, the delay self-closing time of the utility model is relevant to water output. The sealing rubber ring has the advantages of advanced design, good sealing effect, and long service life. When a sealing member is damaged, and delay self closing is invalid, normal operation can proceed through manual control. The utility model which is of strong flushing force can save more than 50% water through being matched with a sealing water tank.

Description

Water volume adjustable self-closing vavle for flushing toilet

The utility model relates to a kind of lavatory self-closing plumbing flush valves of adjustable quantitative.

At present, the delay-self-closing flushing valve of using has various, but because valve is to open by the effect of current fully, influence its water flow so all be subjected to the hydraulic pressure size, when damaging, seal just cannot work simultaneously, and the pressurized seal water tank also has many document announcements, all not have a desirable flushing valve supporting with it, can't realize its water-saving result.

The purpose of this utility model is to make a kind of maximum water flow that all can guarantee under various hydraulic pressure, its delay-self-closing time is only relevant with water yield, the sealing effectiveness of its O-ring seal is better, still can artificially control the self-closing plumbing flush valves of adjustable quantitative that keeps maximum water flow and can be used with the sealing pneumatic storage tank under the O-ring seal damaged condition.

The utility model is made up of: sealing radiator, main valve, fastening swivel nut, water inlet interface etc.

Water inlet interface (2) can be introduced and insert and maintain a distance H bottom it from any part of sealing radiator (1).The sealing and fixing of main valve (3) and sealing radiator (1) realizes by fastening swivel nut (4) and O type cushion rubber (5).

Main valve is made up of main valve body, main valve body capping, set screw, connecting lever, handle etc.Valve body capping (7) is contained in main valve body (6) top and sealing, set screw (8) is housed in the valve body capping (7), the valve body (9) that floats is contained in the main valve body (6), guide position limiter (10) is contained in unsteady valve body (9) top pressing spring (14) and rubber pad (15), spring (14) makes relief valve (17) press rubber pad (15), has water conservancy diversion aperture (12) and the O-ring seal that its lip of U type has chamfering is housed on the valve body (9) that floats.Have metering orifice (11) on the guide position limiter (10), rubber pad (16) is fixed on the bottom of unsteady valve body (9).Axle (18) is located by boss (23) on delivery port (20) inwall and end cap axle sleeve (21),

Make connecting lever (19) aim at pressure release valve rod (17) lower end.Handle (22) is contained in the exit of axle (18).

The course of work of this valve is as follows: when external force rotates connecting lever (19) by handle (22), taking off pressure release valve rod (17) moves vertically upward, make relief valve (17) open pressure release, guide position limiter (10) plays guiding and position-limiting action to relief valve (17), when relief valve leaves when limited, it is spacing that being rotated further of connecting lever (19) moves up to unsteady valve body (9) to be conditioned screw (8).This moment, the open amount of main valve was maximum and be that weighing apparatus is fixed.After external force removes, relief valve (17) is resetted by spring (14) and cuts out, current can only enter unsteady valve body (9) top and pressure accumulation from water conservancy diversion aperture (12) and unsteady valve body (9) moved downward main valve is closed this moment, because the stroke of float trap is that the main valve open amount is set up by set screw (8), set up by set screw (8) so the self-closing time of main valve is only relevant with water yield, irrelevant with hydraulic pressure, so water yield is that weighing apparatus is fixed.When U RunddichtringO (13) damages, because the vertical unlocking amount of relief valve (17) is greater than the leakage rate from U type O-ring seal (13) to valve body (8) top of floating, so pressure can not set up in top to unsteady valve body (8) and connecting lever (19) can easily make unsteady valve body (8) upwards open main valve.

The utility model independently uses when not connecing sealing radiator, and maximum water flow is all arranged under any hydraulic pressure, can economize on water more than 50% when being used with sealing radiator.

Claims

1, a kind of self-closing plumbing flush valves, by sealing radiator, main valve, compositions such as fastening swivel nut, it is characterized in that: the water inlet interface can be located at any part of sealing radiator and insert inside has a distance H with its bottom, being connected by fastening swivel nut (4) of main valve (3) and sealing radiator pushed down main valve (3) and O type cushion rubber (5) comes fit sealing, the unlatching of main valve (3) and relief valve (17) is directly to be acted on by external force making connecting lever (19) rotate upwards vertical unlocking of promotion pressure release valve rod (17), and play the guide and limit effect by guide position limiter (10) and move upward and realize by pressure release valve rod (17) valve body (8) that promote to float again, the lip of U RunddichtringO (13) has chamfering θ, and its inside and outside contact surface all adopts the design of broken line.
