Abstract
An automatic pressure relief valve comprises a valve cover arranged on a valve body, wherein a pressure relief hole and a water outlet hole which are communicated with a valve cavity are formed in the valve body, and a pressure relief mechanism which can automatically open or close the pressure relief hole through water pressure is arranged in the valve cavity. The pressure relief mechanism comprises a sealing gasket and a spring which are arranged in the valve cavity, one end of the spring is connected with the bottom of the sealing gasket, the other end of the spring is pressed on the inner wall of the valve cavity, a water through hole communicated with the water outlet hole is formed in the bottom of the sealing gasket, a water inlet hole is formed in the valve cover, the water inlet hole is communicated with the valve cavity and is located above the sealing gasket, and the pressure relief hole is located below the sealing gasket. The flow area of the water through hole is smaller than that of the water inlet hole. The pressure relief hole is located below the side of the gasket. The sealing gasket is in a bowl shape or a barrel shape. The spring is a cylindrical spring or a plate spring. Compared with the existing automatic pressure release valve, the automatic pressure release valve has the characteristics of simple and reasonable structure, flexible operation, few parts and low manufacturing cost.
Description
Technical field
The present invention relates to a kind of automatic decompression valve.
Background technique
Chinese patent literature CN 201053521 Y disclose a kind of automatic decompression valve on April 30th, 2008, valve body is provided with valve pocket and is communicated with water intake and the water outlet of valve pocket, be provided with a spool that can move up and down in the valve pocket and close and open the return flow line, spool comprises valve plug and the spring that joins with it, water intake is located at an end of valve pocket, water outlet is located at the valve pocket the other end relative with water intake, and the hollow valve plug is located at water inlet position; When the water of high pressure during with backflow needle jack-up, spool upper end plug blocks the valve pocket in the needle, thus the closing volume passage; Utilize the weight of backflow spool self that the reflux valve spool is fallen down when hydraulic pressure reduces and open the return flow line, the upper end of valve plug is to the distance of the passway length greater than spool.This automatic decompression valve relatively simple for structure still, requires more accurate to the own wt of backflow needle, factor requires higher to external world, and because the reasons in structure restriction is only applicable to the low-pressure environment, the up-to-standard rate of finished product is also lower, is difficult to satisfy user's requirement.
Summary of the invention
Purpose of the present invention aims to provide a kind of simple and reasonable, flexible operation, component are few, fabricating cost is low automatic decompression valve, to overcome deficiency of the prior art.
A kind of automatic decompression valve by this purpose design comprises the valve gap that is arranged on the valve body, is provided with the relief hole and the osculum that communicate with valve pocket on the valve body, and its structure characteristic is to be provided with the decompression mechanism that automatically opens or closes relief hole by hydraulic pressure in the valve pocket.
Described decompression mechanism comprises sealing gasket and the spring that is arranged in the valve pocket, one end of this spring and the bottom connection of sealing gasket, the other end of spring is crimped on the inwall of valve pocket, the bottom of sealing gasket is provided with the water passage hole that communicates with osculum, be provided with the water inlet on the valve gap, this water inlet communicates with valve pocket and is positioned at the top of sealing gasket, and relief hole is positioned at the below of sealing gasket.
The circulation area of the circulation area＜water inlet of described water passage hole.
Described relief hole is positioned at the side-lower of sealing gasket.
Described sealing gasket is bowl dress or tubular.
Described sealing gasket is that silica gel or metal are made.
Described spring is column spring or plate-shaped springs.
After the present invention adopts above-mentioned technological scheme, under the effect of hydraulic pressure, by sealing gasket and spring stretch realize closing or opening relief hole, thereby reach self-relieving purpose.
When pump working, under the effect of hydraulic pressure, when water pump pumps next water through the water inlet on the valve gap, when entering the sealing gasket that is arranged in valve pocket, because the water passage hole on the sealing gasket is very little, and the circulation area of the circulation area＜water inlet of water passage hole, thereby in valve pocket, produce hydraulic pressure, namely in sealing gasket, produce hydraulic pressure, make sealing gasket distortion, so under the effect of the elasticity of the elastic force that overcomes spring and sealing gasket, sealing gasket moves downward, thereby seal the relief hole that is positioned at sealing gasket below, water under normal circumstances is the osculum outflow from the valve body just; When water pump quit work, the pressure in the sealing gasket reduced rapidly.Sealing gasket moves upward under the effect of self spring-back force and spring force, and relief hole is opened, real new releasing pressure automatically.
The present invention is with respect to existing automatic decompression valve, has simple and reasonable, flexible operation, component are few, fabricating cost is low, pressure release is effective characteristics.
