Corrugated pipe is used as isolation element, separating the two kinds of medium or preventing the harmful fluid into the equipment.
Bellows valve in the work process, the bellows and the stem work together with axial displacement and reset, while it also bears the pressure of fluid and absolute seal. The working stroke of the bellows is generally the 1/4 of path. The axial displacement of the corrugated pipe should be limited by the mechanical limit through the valve stem, which is not allowed to plastic deformation and distortion.
The cut-off valve, throttle valve, regulating valve, pressure reducing valve in the field of nuclear industry, petroleum, chemical, pharmaceutical, aerospace and so on.
