China Marine valve manufacturer shares with you.
The check valve device should pay attention to the following:
1. Do not allow the check valve to accept weight in the pipeline. Large check valves should be independently supported so that they are not affected by the pressure generated by the piping system.
2. Pay attention to the direction of medium movement when installing the device and the direction of the arrow marked on the valve body.
3. The lifting straight flap check valve should be installed on the straight pipe.
4. The lifting horizontal flap check valve should be installed on the horizontal pipeline.
The lifting check valve has good sealing and large fluid resistance. It should be installed horizontally on a horizontal pipeline and vertically on a straight pipeline.
The orientation of the swing check valve is not restricted. It can be installed on horizontal, straight or skewed pipelines, such as on straight pipes, and the medium flow should be from bottom to top.
The swing check valve, also known as a check valve, is an automatic valve used to prevent the medium from flowing backward in a one-way flow pipeline. It can be opened or closed by the pressure of the medium flowing in the pipeline. It can be divided into a single-lobe type. There are three types of valves, double-lobe type, and multi-solution type, which are one of the more commonly used valves. Swing check valve is generally suitable for pipelines with relatively clean fluid media, and is not suitable for working conditions with high viscosity or containing solid particles, otherwise, it will cause the check valve to open insensitively, fail to achieve a complete seal, and check the fluid. It is not reliable enough. The swing check valve only allows the medium to flow in one direction, which can effectively prevent the medium from flowing backward to prevent accidents.
Our company provides a Wafer type check valve.
