Pressure Test Method Of Check Valve

Pressure Test Method Of Check Valve
Check valve is a valve that relies on the medium itself to flow and automatically open and close the valve flap, used to prevent the backflow of the medium, also known as check valve, check valve, backflow valve, and back pressure valve.
Check Valve

Common Check Valve Materials
Check valve is a valve installed in the pipeline to prevent the backflow of media. Check valves can be used on many types of pipelines such as over water, oil and gas, etc.
Butterfly Valve

Background of Butterfly Valve
Butterfly valve is a type of valve that uses a spherical butterfly plate as the opening and last component and turns with the valve stem to open, close and alter the fluid channel. the butterfly plate of the butterfly valve is set up in the diameter route of the pipe. in the cylindrical channel of the butterfly valve frame, the disc formed butterfly plate rotates around the axis of the valve stem at an perspective among 0 ° and 0 °. whilst the butterfly plate is at 0 °, the valve is closed, and when the butterfly plate is at ninety °, the valve is absolutely opened.

Check Valve Applications

Check Valve Applications
The purpose of using check valve is to avoid the backflow of medium, generally in the outlet of the pump should be installed check valve. In addition, the outlet of the compressor should also be installed check valve. In summary, in order to avoid the backflow of the medium, in the equipment, installation or pipeline should be installed check valve in general in the nominal diameter of 50mm of the horizontal pipeline are selected vertical lift check valve. Straight lift check valve in the horizontal pipeline and straight pipeline can be installed.
Pressure test method of check valve

Pressure test method of check valve
Check valve refers to the valve that automatically opens and closes the valve flap by relying on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve.
Wafer Type Dual Check Valve

The principle of check valve opening and closing
The check valve opening and closing parts are opened or closed by themselves by the flow and force of the medium to prevent the backflow of the medium. The valve is called a check valve. The check valve belongs to the automatic valve category, which is mainly used in the pipeline where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents. The check valve, also known as a one-way valve or a check valve, is used to prevent the backflow of the medium in the pipeline.
Gate Valve

The Advantages Of Gate Valve
Gate valve is a kind of cut-off valve, which is used to connect or cut off the medium in the pipeline. Gate valve's opening and closing member gate, driven by the valve stem, extend the seat to do linear lifting movement.Advantages of the gate valve.1. low fluid resistanceBecause the valve body of the gate valve internal media channel is straight, the media flow through the gate valve does not change its flow direction, so the fluid resistance is small.2.
The meaning of butterfly valve and the problems that are easily overlooked in the use process

The meaning of butterfly valve and the problems that are easily overlooked in the use process
In production and life, the emergence of valves is that the utilization rate of their valves and accessories is getting higher and higher, such as check valves, check valves, electric butterfly valves, pneumatic butterfly valves, rubber soft joints, electric ball valves, one-way valves, and wafer butterfly valves. , filter, etc., which have brought great convenience to production and life.
