Application of pneumatic ball valve in actual pipeline pneumatic ball valve can be used as a pipeline compensation joint for loose joints of various water supply pipelines. The pneumatic ball valve mainly has a certain multi-directional and unique role in pipeline operation, and plays an important role in expansion and contraction compensation of the pipeline due to thermal expansion and contraction, crustal subsidence and stress during operation. Therefore, the pneumatic ball valve can alleviate the thrust of the blind plate during pipeline operation, and play a certain role in protecting the pipeline, especially providing great convenience for pipeline installation and maintenance.
However, at the pump outlet and pipe corner, pneumatic ball valve and limit pneumatic ball valve, or limit expansion device and anti pull off limit valve connector, and limit pneumatic ball valve and clamp flexible connector can be used in the sliding pipe connection without fixed buttress, infinite buttress and directional limit pier support, Because the pneumatic ball valve can transmit the thrust of the blind plate when starting the pump to the pump and various parts of the pipeline through the force transmission bolt, so as to avoid the thrust concentrated at the pipe corner or the near end of the pump, causing impact damage to the equipment.
