Formula check valve has threaded connection, board-like connection and three kinds of forms of flanged joint, existing check valve that can generate noise, in use
It frequently results in flap and smashes and flow backwards with medium, for this purpose, it is proposed that a kind of one-way valve structures.
【Utility model content】
The main purpose of the utility model is that providing a kind of one-way valve structures, asking in background technology can be effectively solved
Topic.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of one-way valve structures including main body, spring, raft valve, O-ring, valve seat and connector, are provided in the main body
Spring, the spring end connect raft valve, and the raft valve one side is provided with valve seat, and the valve seat is located in connector, the company
Junctor one end is located in main body, and O-ring is provided between the raft valve and valve seat, and filter screen, institute are provided in the connector
It states connector one side and is provided with fluid oscillation formula flowmeter, the bottom part body is provided with vibration alarm, the vibration alarming
Device one end is provided with temperature sensor.
Further, the quantity of the O-ring is multiple.
Further, the main body is fixedly connected by bolt with connector.
Further, the main body and raft valve are fixedly connected by bolt with spring.
Compared with prior art, the utility model has the advantages that：By setting main body and connector so that single
The structure of fixing-stable is formed to valve, by setting spring, spring promotes raft valve to be connected with O-ring and valve seat, closes valve body,
When fluid enters from connector and valve seat in valve body, raft valve compresses spring under pressure, and is moved to one side, and valve body is beaten
It opens, fluid flows through, and after fluid all flows through, raft valve is connected under fluid and spring effect with O-ring and valve seat, and valve body is sealed
It closes, prevents fluid reflux, main body, raft valve, valve seat and connector are made of alloy 400, and intensity and toughness etc. are excellent, prevent
When raft valve both sides Fluid pressure is close, flap is often patted with valve seat, and causes flap broken, while valve seat is elastic packing
Enclose valve seat, it is noiseless, can effectively anti-backflow, by setting O-ring, O-ring material is fluorubber, can be had to valve body
The sealing of effect by setting filter screen, convenient for the contaminant filter in fluid is got off, is prevented from causing to block in valve inner, drawn
It rises and flows backwards, by setting fluid oscillation formula flowmeter, convenient for measuring the Fluid Volume flowed through, in valve body failure, it will usually generate
Vibration, by setting vibration alarm, can warn to people, by set temperature sensor, understand fluid convenient for people
Temperature.
