What is the difference between expansion joints and double flange pneumatic ball valves? Expansion joints can also be called pipe expansion joints, pneumatic valves, and pneumatic ball valves. Expansion joints are divided into several types: corrugated expansion joints, sleeve expansion joints, square natural compensation expansion joints, among which corrugated expansion joints are more commonly used. Do you know the difference between expansion joints and double flange pneumatic ball valves?
The expansion joint manufacturer will analyze for you as follows: the double flange limit pneumatic ball valve is composed of main parts such as body, seal ring, gland, expansion spool, etc. On the basis of the original performance of loose tube pneumatic ball valve, a limit device is added, and double nuts are used to lock the maximum expansion. The pipeline can expand and contract freely in the allowable expansion and contraction amount. Once the maximum expansion and contraction amount is exceeded, the limit will be reached to ensure the safe operation of the pipeline. It is especially suitable for the connection in the pipeline with vibration or a certain slope and turn. The double flange pneumatic ball valve is composed of loose flange pneumatic ball valve, short pipe flange, force transfer screw and other components, which can reduce the pressure thrust (blind plate force) of the connected parts and compensate the installation error of the pipeline. The double flange pneumatic ball valve cannot absorb the axial displacement. Double flange power connection is mainly used for loose sleeve connection of pump, valve and other accessories. The double flange loose sleeve pneumatic ball valve is composed of loose sleeve pneumatic ball valve, short pipe flange, force transfer screw and other components. It can transfer the pressure thrust (blind plate force) of the connected parts and compensate for pipeline errors, and cannot absorb axial displacement. It is important for loose sleeve connection of pump, valve, pipeline and other accessories. The above is the content shared for you, and I hope it will be helpful to you.
