Problems solved by technology

[0002] Due to the screw-locked connection between the valve body and the pressure regulating cover in the existing water flow pressure reducing valve, and the influence of water flow impurities is not considered, the pressure reducing valve has a large volume and high production cost, which may easily cause water flow impurities to enter the water flow. The pressure reducing valve affects the effect of water flow decompression and damages the water flow pressure reducing valve. In addition, the existing water flow pressure reducing valve and the pipe thread connection are sealed with sealing tape, which is easy to cause the valve body to be screwed too deep when the pipe is screwed in. Cracking or poor sealing, and because the internal reverse sealing adopts flat sealing, there are also deficiencies such as unreasonable design and poor sealing effect

Abstract

It relates to a current pressure reducing valve. It comprises a valve, valve core bar, pressure regulating cover, involucra, spring, spring base, regulating pressure screw, nut, epithelial pressure plate, O type ring of valve core bar, O type rings behind and before the pressure reducing valve base, pressure reducing valve base, seal gasket, seal gasket pressure plate, hexagonal cap, block and return hole, with inner thread on the valve fitting with the outside thread of the pressure regulating cap. It is reasonable, reliable in connection, convenient in installation, clean in working environment, endurable, good in performance and low in cost.

Description

technical field [0001] The invention relates to a decompression valve, in particular to a water flow decompression valve. Background technique [0002] Because the existing water flow pressure reducing valve is connected by screw locking between the valve body and the pressure regulating cover, and the influence of water flow impurities is not considered, the pressure reducing valve has a large volume and high production cost, which may easily cause water flow impurities to enter the water flow. The pressure reducing valve affects the effect of water flow decompression and damages the water flow pressure reducing valve. In addition, the existing water flow pressure reducing valve and the pipeline thread connection are all sealed with sealing tape, which is easy to cause the valve body to be screwed in too deeply when the pipeline is screwed in. Cracking or poor sealing, and because the internal reverse sealing adopts plane sealing, there are also defi...
