Abstract

The utility model relates to an automatic water-saving flushing valve, which makes an improvement to a parallel installing type water-saving flushing valve and a vertical installing type water-saving flushing valve. The automatic water-saving flushing valve is composed of a T-shaped valve body, a piston assembly, a press button assembly, a valve top cover, and a water outlet. When the automatic water-saving flushing valve is used, the automatic flushing and the automatic time-delay closure can be carried out by slightly pressing the press button. The utility model has the advantages of convenient installation and maintenance, simple use and adjustment, water saving, beautiful appearance, and long service life. The utility model is particularly suitable for flushing toilet urinals.

Description

Automatic water-saving flushing valve

A kind of water saving automatic flush valve is to parallel installing type and directly a kind of improvement of installing type water-saving valve, relates to a kind of hygiene apparatus.

At present, the water saving flushing valve mostly is parallel installing type and direct installing type.Parallel installing type flushing valve is installed inconvenient, and the bend pipe, the folding that need to increase by one 90 degree are repaiied also not convenient; Directly the installing type flushing valve is a straight tube shape valve body, and water inlet directly washes away piston, because various places hydraulic pressure is inequality, it is excessive to be easy to generate hydraulic pressure, closes incessantly water, and hydraulic pressure is too small, puts the phenomenon of not water outlet, makes the difficulty of assembling timing." flushing valve of delayed self-close urinal " of selling on the market, though can overcome above-mentioned shortcoming, this device starts flushing by the rotation knob, and knob is positioned at water-saving valve upper end, operates more time-consumingly, the elasticity of return spring can not be regulated.

The purpose of this utility model just provides and a kind ofly can wash automatically, delay-self-closing, have that installation and maintenance are easy, the adjustable water saving automatic flush valve of the elasticity of return spring again.

The technical scheme that the utility model solves is: the water saving automatic flush valve, has " r " shape valve body, piston assembly, button assembly, delivery port, the main points of its scheme are that " r " shape valve body fork angle is 55 degree, the button assembly is positioned at the valve body outside, and piston lever and piston assembly flexible connection by being positioned at valve body, meantime screw is positioned on the valve top cover at valve body fork angle, and delivery port is positioned at valve body lower end.

Piston assembly of the present utility model is by piston, piston lever, back-moving spring, spring top cover, piston U-shaped sealing ring, and valve seat insert is formed.

Button assembly of the present utility model is made up of button, bellows, push rod.

Delivery port of the present utility model is made up of oviduct sealing ring, air cut off device, aperture.

The utility model has the advantages that: 1, as long as press button gently, can wash automatically, automatic delayed closes, and operates portable and smart; 2, by the adjustment screw on the control valve top cover, can regulate the time-delay washing time; 3, at the mouth of a river that flushes out of valve the convergent horn mouth is housed, makes press water when flowing into cleaning hose, around nozzle, cause negative pressure, make the aperture on the air cut off device suck air, therefore play the effect of air partition, can prevent that sewage backflow from polluting.

Fig. 1 is a structure chart of the present utility model.

1r shape valve body, 2 water inlet nuts, 3 water supply connectors, 4 joint sealing circles, 5 valve top seal circles, 6 valve top covers, 7 meantime screws, 8 meantime screw sealing rings, 9 spring top covers, 10 back-moving springs, 11 piston U-shaped sealing rings, 12 piston levers, 13 packing rings, 14 pistons, 15 valve seat inserts, 16 push rods, 17 oviduct sealing rings, 18 buttons, 19 air cut off devices, 20 oviducts, 21 apertures, 22 water output ducts, 23 piston assemblies, 24 bellowss, 25 button assemblies, 26 delivery ports.

Fig. 2 is the structure chart of the utility model button.

24 bellowss, 27 button end caps.

Below in conjunction with embodiment and accompanying drawing the utility model is further described.

With reference to accompanying drawing 1, have " r " shape valve body (1), its fork angle is 55 degree, valve body (1) upper end is a water inlet, is made up of water inlet nut (2), joint sealing circle (4) and water supply connector (3); Valve body (1) fork top, angle is connected with valve top cover (6), and there are meantime screw (7) meantime screw sealing ring (8) and valve top seal circle (5) in valve top cover (6) middle part; Valve body (1) fork has piston (14) in the angle, pass a piston lever (12) in the middle of the piston (14), one end of piston lever (12) flexibly connects by spring top cover (9), back-moving spring (10), the other end contacts with an end of push rod (16), and the other end of push rod (16) is connected with the button (18) that is positioned at valve body (1) outside; Delivery port is positioned at the lower end of valve body (1), and by oviduct (20), aperture (21) is connected by air cut off device (19) with water output duct.

When using the utility model, as long as push a knob down (18) lightly, push rod (16) promotes piston lever (12) downwards, make it to depart between the center line of piston (14) and the piston (14) and produce the slit, the pressure on piston (14) top is less than hydraulic pressure, piston (14) rises, and press water flows into cleaning hose immediately; When release button (18), piston lever (12) is by back-moving spring (10) effect and reset, and the aperture of the logical piston of press water upper end enters the space on piston (14) top, suppresses descent of piston to reset, and closes water inlet, and flushing stops automatically.Adjust washing time as need, the meantime screw (7) of adjustable valve top cover (6) upper end.Reference time delay 4-7 second.
