Tight corresponding hole sealing plate, further increases leakproofness, ensures the partition effect between each quantitative chamber.And there are sealing compression bar, pressure
After tight plate, the too tight of pressure is not had to during fabrication, between hole sealing plate and diaphragm plate（Leakproofness can be protected by the pushing of pressure plate
Barrier）, so as to effectively reduce abrasion, prolong the service life.It is noted that after having sealing compression bar, pressure plate, turn allowing
Before the motionless and turn core pipe of dynamic pipe, pressure plate should be allowed to be not located at the state for compressing corresponding hole sealing plate, otherwise will appear " turning motionless "
The case where.
