Valve installation knowledge in the fluorine lined check valve industry

With the continuous expansion of the valve industry, the types of valves are also gradually increasing. For example, clamp type Fluorine-lined Butterfly Valve Pneumatic ball valve Fluorine lined DC globe valve Wait. And today we will talk about the widely used valves in the valve industry, which are check valve The main function of the so-called fluorine lined check valve is to only allow the medium to flow in one direction and prevent directional flow. Usually, this type of valve works automatically, and under the pressure of fluid flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the pressure of the fluid and the self weight of the valve disc act on the valve seat, thereby cutting off the flow.

When it comes to the relevant knowledge of fluorine lined check valves, we have to talk about the installation knowledge of these fluorine lined valves. Firstly, during installation, attention should be paid to checking whether the valve markings match the usage requirements, and whether the flow direction markings on the shell are consistent with the flow direction of the pipeline. Secondly, during installation, try to install horizontally with the valve stem facing upwards. To prevent the valve from tilting and allowing it to be installed in its natural state, and to prevent significant installation stress caused by pipelines, supports, etc., the valve should not be lifted using a handwheel during installation. If the sealing surface of the pipeline flange connected to the fluoroplastic lining sealing surface at both ends of the valve is metal, a fluoroplastic sealing gasket must be added. Of course, when we complete the installation and conduct pressure testing on the system or pipeline, the valve must be in the fully open position.
