Preferably, screw rod is configured in the screw rod mounting base.
The beneficial effects of the utility model：
Sanitation-grade diaphragm provided by the utility model, the characteristic that two kinds of materials are utilized use, and utilize the tension of PTFE
Intensity ensures PTFE as inner layer piece the tensile strength of diaphragm, using the excellent compression strength of PFA using it as outer layer
Piece, at the same using the hardness of PFA more than PTFE the characteristics of come welding PFA as the sealing system of diaphragm, can effectively carry in this way
The wear-resistant resistance to compression of high sealing muscle reduces the diaphragm caused by sealed muscle formation abrasion and damages, while PFA has very strong shock resistance
Ability also just improves tearing risk of the diaphragm under medium high speed impact.
