Valve connection method
2020-12-21
Valves are commonly used in life, no matter where, what occasions can be seen, different occasions different valves use different connection methods, the following is a detailed description of what are the valve connection methods,
1. Valve flange connection
It’s the valve body with flanges at both ends, corresponding to the flange on the pipeline, through the bolt fixed flange installed in the pipeline. Flange connection is a much-used connection form in the valve. Flanges are convex (RF), flat (FF), convex and concave (MF), etc.
2. Valve wafer connection
Valve installed in the middle of the two flanges, the valve body usually has positioning holes to facilitate the installation of positioning, with bolts directly to the valve and the two ends of the pipe wear clamped together in the form of connection.
3. Valve welding connection.
The valve body ends are processed into butt welding bevels according to the requirements of butt welding, corresponding to the pipe welding bevels, fixed in the pipe by welding.
4. Valve socket welding connection.
The two ends of the valve body are processed according to the socket welding requirements, and the pipeline is connected by socket welding.
5. Valve threaded connection
Threaded connection is a simple connection method, commonly used in small valves. The valve body is processed according to each thread standard, and there are two kinds of internal and external threads. Corresponding to the thread on the pipe.
6. Valve clamp connection
This is a quick connection method, which requires only two bolts, and is suitable for frequently disassembled low-pressure valves. Such as sanitary valves.
7. Self-tightening connection inside the valve
The above various connection forms are used to counteract the medium pressure and achieve sealing by using external forces. It is also possible to use the medium pressure for self-tightening connection form.
