Face and secondary sealing area；
Rear cover, rear cover have the rear cover sealing surface cooperated with primary sealing area, are equipped on rear cover sealing surface several and fixed
The location hole of position salient point cooperation is equipped with the rear cover sealing edge for limit in the outer edge position of rear cover sealing surface；
End cap, end cap have the end cap seal face cooperated with secondary sealing area, are equipped on the end cap seal face several
Fixing screwed hole；
Fixing screws, fixing screws pass through after the via hole of location hole and positioning convex point with the fixed thread on end cap seal face
Hole is connected and fixed, and fixing screws are used for end cap seal face and secondary sealing area, primary sealing area and rear cover sealing surface, gasket
Outer end face and the positioning convex point and location hole of rear cover sealing edge and gasket fit closely to form sealing.
Further, the outwardly extending cylindrical body of the positioning convex point of the gasket, after the location hole that covers be cylindrical body
Groove.
Compared with prior art, the utility model has the beneficial effects that:
By the positioning convex point with rear cover cooperation being located on gasket, easy to assembly, good manufacturability, gasket is directly filled
Enter rear cover, the position of gasket is fixed, sealed reliable.
