Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is profile of the present utility model.
Fig. 2 is the semi-cutaway of the utility model valve disc.
Fig. 3 is the front view of the utility model main shaft.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Diaphragm center installs main shaft, accompanies pressing plate up and down, is fastened by nut, between bonnet and middle valve body, middle valve body
On valve body angled end-face, middle valve body boss and valve body inclined hole are gap cooperation, using the O-ring static seal of valve body end face,
Middle valve body and barrier film are anchored between valve body and bonnet by several bolts, and bushing is spun solid in middle valve body, are sealed using screw thread glue,
Main shaft is installed in bush hole, is coordinated for gap, using two pass O-ring dynamic sealing；Spindle top is equipped with pressing plate and barrier film, lower side axle
Valve disc is housed, valve disc is fastened by packing ring, nut, and the cylinder of main shaft latter end is threaded onto in valve seat orifice, kept jointly with bushing at shoulder
The precision that valve disc is run up and down；Spring is installed between middle valve body and valve disc, and valve seat is spun solid in valve body, is sealed using screw thread glue；
Usually the common pressure chamber below barrier film leads to air, and the control chamber of diaphragm, plus the collective effect of spring, makes valve filled with pressure source
