The invention has the advantages of simple structure, small occupied space, high system integration level, long service life, easy installation and maintenance, simplicity, convenience and strong reliability.

Description

Highly-integrated one-way valve
Technical Field
The invention relates to a high-integration one-way valve, and belongs to the field of valves.
Background
The check valve only allows fluid to want single direction movement, and when fluid moved to opposite direction, the check valve can be closed by oneself to prevent that high pressure from getting into low pressure system, at present, the check valve mainly comprises joint, rubber pad, brace, spring and lower clutch, and the rubber pad relies on the spring to play the supporting role, simple structure, but long-term use and when receiving pressure shock, the spring can take place the skew, causes the rubber pad to produce the slope, and the sealed effect of valve receives very big influence.
Disclosure of Invention
In order to alleviate the defects of the prior art, the invention aims to provide the high-integration one-way valve which is simple in structure, small in occupied space, high in system integration level, long in service life, easy to install and maintain, simple and convenient and strong in reliability.
In order to achieve the purpose, the invention adopts the following technical scheme:
check valve, including the valve body, its characterized in that: the inner cavity of the valve body is provided with a horizontal valve rod, the left end and the right end of the horizontal valve rod are respectively provided with a valve guide sleeve and a rubber valve, the outer wall of the horizontal valve rod is further sleeved with a spring, the spring is clamped between the valve guide sleeve and the rubber valve, and the left side of the valve body is connected with a two-way connector.
The check valve is characterized in that: and a nut and an O-shaped sealing ring are arranged between the two-way joint and the valve body.
The check valve is characterized in that: and a sealing ring is also arranged on the right side of the nut.
The invention has the advantages that:
the invention has the advantages of simple structure, small occupied space, high system integration level, long service life, easy installation and maintenance, simplicity, convenience and strong reliability.
