Abstract

The utility model discloses a flushing valve which is used for a liquid pressure pipe and is particularly used for sanitary ware for urination and defecation. The utility model is composed of a valve seat (1), a hydraulic operated starting and stopping mechanism (2), a valve cover (5), etc. A valve stem (9) is controlled by a button (7) to change liquid pressure in a water filling cavity (12), and the flushing valve is started and stopped. The size of the water filling cavity is changed by a regulating plug (6) to control water flushing quantity and water flushing time, and the process is free from the affection of high pressure and low pressure. The closing direction of a piston is opposite to the direction of water flow, the closing speed is stable, and the water saving effect is obvious.

Description

A kind of flushing valve

The utility model is a kind of flushing valve, is applicable to that liquid pressure conduit opens and closes, and is specially adapted to greatly, and the flushing of urine sanitary ware is a kind of energy-conserving product.

In the large and small just sanitary ware Rinsing unit that uses at present, the employing core-skin valve that has, but the existence of core-skin valve does not have shortcomings such as self-closing function, water resource waste, the delay-self-closing flushing valve of the multiple structure of employing that also has, existence can not control the amount of flush water size and delay time long, low pressure can not be closed, opening time-delay length is subjected to variation in water pressure and changes, I had once designed a kind of efficient flushing valve (patent No.: 93202989.2) at the beginning of 93, but because the time-delay metering-orifice is difficult for changing, control amount of flush water size, time are difficult for defectives such as adjusting.

The utility model purpose is to improve original flushing valve, and a kind of delay-self-closing function that has is provided, and can arbitrarily control amount of flush water and bath time, and closing velocity is steady, a kind of flushing valve that not just influenced by hydraulic pressure.

The utility model is by valve seat (1), opening/closing mechanism (2) surges, valve gap compositions such as (5), it is characterized in that valve seat (1) upper edge have spilled water hole (3) from the upper edge sensible valve seat low pressure area, surge opening/closing mechanism (2) by button (7), Returnning spring (8), valve rod (9), adjusting plug (6), water filling cavity (12), piston (15), time-delay hole assembly (14), water inlet (16), time-delay hole (13), ring (10) sluices, weep hole compositions such as (11), inboard and the valve seat (1) of valve gap (5), the opening/closing mechanism (2) that surges constitutes sluicing chamber (4), adjusting plug (6) can move up and down in the middle of valve gap (5) and valve seat (1), control water filling cavity size, water inlet (16) are at piston (15) center.

The utility model in use since valve body in water filling cavity lower piston surface greater than the piston lower surface, piston is throttle down from top to bottom, when valve opening, water filling cavity fluid pressure or move up less than the intake pressure piston and to open valve, liquid enters water filling cavity simultaneously, and only be full of, valve closing, reach the delay-self-closing function, by on the adjusting plug, move change water filling cavity size down simultaneously, reach control amount of flush water and bath time, water-saving result is obvious, and closing velocity is steady, easy to operate.

Description of drawings

The whole sectional drawing of a kind of embodiment of Fig. 1 the utility model

(1) valve seat; (2) opening/closing mechanism that surges; (3) spilled water hole; (4) sluicing chamber; (5) valve gap; (6) adjusting plug; (7) button; (8) Returnning spring; (9) valve rod; (10) sluicing ring; (11) weep hole; (12) water filling cavity; (13) time-delay hole; (14) time-delay hole assembly; (15) piston; (16) water inlet.

The invention will be further described below in conjunction with embodiment:

The utility model is made up of valve seat (1), the opening/closing mechanism that surges (2), valve gap (5) etc., before the flushing, because pipeline pressure water enters in the water filling cavity (12) from the water inlet (16) of piston (15) bottom, the time-delay hole (13) at delay time hole assembly (14), center, because piston upper surface is greater than lower surface, valve is in closed condition.During flushing, press the button (7), driving valve lever (9) passes downwards, the water-filling intracavity liquid is from the sluicing ring (10) of valve rod, weep hole in adjusting plug (11), sluicing chamber (4), the low hydraulic pressure place of the spilled water hole of valve seat (3) flow valve, water filling cavity pressure reduces, piston moves up, valve open, because Returnning spring (8) Operating valve rod resets, liquid is no longer gone out from sluicing circulation, simultaneously because time-delay tiny time-delay hole, assembly center, hole (13) effect, liquid progresses into water filling cavity and only is full of water filling cavity from the time-delay hole, piston moves down, throttle down plays the time-delay closing effect, by control amount of delay hole size with by adjusting plug control water filling cavity size, control amount of flush water and washing time, and have self-closing function, easy to operate, water-saving result is obvious, the piston closing direction is opposite with water (flow) direction, plays the steady effect of closing.This flushing valve is made with brass material, and it is latent to avoid the yielding grade of plastic casing to lack, and not limited by the region, is a kind of desirable flushing valve.

Claims

1, a kind of flushing valve that is used for the fluid pipeline switching, by valve seat (1), the opening/closing mechanism that surges (2), valve gap (5) is formed, and it is characterized in that:
