Abstract

The utility model relates to a push valve for the tap water pipe and the hot water pipe, which is mainly composed of a valve body, a locking cap, a sealing ring, a valve clack, a push rod, a spring, a key cover, a serrate rotating wheel, a valve cover, a threaded sleeve of the screw-pitch, a press pipe and a button. The valve is characterized in that firstly, due to adopt reciprocating type opening and shutting, the valve clack has few abrasions, and the feeding water and cutting off is rapid, and thus the valve is easy in use and save water. Secondly, the valve clack is in a cone shape; beside the compressing by elastic force, the water pressure can also be used for assisting compressing, and thus the sealing performance is good. Thirdly, the reciprocating type opening and shutting cause few abrasions, and thus the service life is long. Fourthly, the quantity of water can be adjusted by the adjusting threaded sleeve. Fifthly, the valve has a wide range of application such as the cut-off valve for the tap water pipe and the hot water pipe, the flashing valve of the toilet, the water supply valve of the water heater and the water faucet.

Description

Push valve

The utility model relates to the valve new varieties, the true hardware of using.

Existing be used on the water supply pipe and hot water pipeline on valve: all adopt rotary pushing mechanism to open or close flap as water nozzle, stop valve, ball valve, stopcock or the like, use inconvenience so all exist, easy to wear, poor sealing, service time, length will seepage, short-life shortcoming.

The purpose of this utility model provides a kind of easy to use, good airproof performance, the push valve of long service life.

The utility model is to adopt reciprocating type pushing mechanism to order about flap to open or close, to reduce wear, set up seal washer at flap push rod and valve body hole cooperation place, water can not released from the cooperation place, the flap closing direction is consistent with the hydraulic pressure direction, makes hydraulic pressure assist the mode of sealing to achieve the goal.

The utility model characteristics: the one, adopt push type (reciprocating type) to open or close valve, water flowing or cut off the water supply fast, easy to use, conserve water; The 2nd, utilize hydraulic pressure to add the spring force of self, compress flap, good airproof performance; The 3rd, reciprocating type pass or open, the flap wearing and tearing are few, long service life; The 4th, the water yield can be regulated; The 5th, applied widely, can make stop valve on the cold and hot pipeline, lavatory flashing valve, water supply of water heater valve and water nozzle.

Below in conjunction with accompanying drawing embodiment is described:

Fig. 1 is this valve water nozzle type partial, longitudinal cross-sectional.

Fig. 2 is this valve brand mark figure.
