Design Feature
Suitable for the condition that the process gas is not allowed to leak into the atmosphere.and the sealing gas is not allowed to enter the machine;In addition to the process gas itself,also need another nitrogen gas as a second stage sealing gas,when the first stage seal fail,second stageseal can play auxiliary safety role;
