Metal corrugated pipe in the application of the pneumatic valve (3)

ripple and pressure, axial force, lateral force, or metal tube can generate the corresponding displacement, bending properties and with the pressure, vacuum sealing, corrosion resistance, temperature stability and long service life. Therefore, it is more and more widely used in many industrial fields.
bellows seal pneumatic valve components in the application of separation. In both by the pneumatic valve, pneumatic valve, throttle control pneumatic valve or corrugated pipe pressure changes reduced pressure pneumatic valve, pneumatic valve, corrugated pipe of pneumatic valve stem packing seal as isolated components. Work in the process of pneumatic valve, corrugated pipe with dry axial displacement and reset. It also fluid under pressure, and ensure the seal. Relative to the packing seal pneumatic valve, with greater reliability and service life of pneumatic valve bellows. As a result, corrugated pipe pneumatic valve in the nuclear industry, petroleum, chemical industry, medicine and aerospace industries has been widely applied.
in practice, often such as flange, nozzle, and as a dry other welding bellows, etc, formed the bellows components. Bellows welded into indispensable an important part in the process of production. With the research and the development of the corrugated pipe welding device and equipment production put forward the new requirements. According to these requirements, it is necessary to develop new corrugated pipe welding equipment.
