Three links of pneumatic valve pneumatic valve stem leakage protection design is introduced

Three-way solenoid pneumatic valve stem leakage protection design is as follows:






1, pneumatic valve stem on the proof design.


2, one phase sealing, cone-shaped pneumatic valve stem seal prevent leakage of medium in the process of pneumatic valve rod rotation, and in the condition of abnormal pressure, also can effectively prevent leakage.

3, two phase, a set of v-shaped combination packing after being compressed into expansion, on both sides to prevent leakage.

4, compression release of disc spring preload force automatically compensate the wear and tear of pneumatic valve stem packing and gasket.

5, using pneumatic stem nut pressure all pneumatic valve stem seal system, to prevent leakage. Check back cushion fixed pneumatic stem nut, prevent them from loosening.

6, switch lock when must keep the position of the existing pneumatic valve to prevent the risk of wrong operation by accident.
