The path at the axial two ends of shell 11, sealing breathable film 20 is arranged on the inner side end of outer ring 111.There is connection at the middle part of outer ring 111
It is connection between post 112, the meeting stile 113 for having radial arrangement between connecting pole 112 and the inwall of outer ring 111, meeting stile 113
The path at the axial two ends of shell 11, the inner side of outer ring 111 is arranged in through connecting pole 112 in the sealing breathable film 20 of O-shaped shape
On end face, i.e., on the path between meeting stile 113, then the devices such as safe valve body 10 and casing, pipeline are coordinated
Install, reach the purpose of waterproof and breathable.
Valve pad 12 is provided with the inner side end of described outer ring 111, valve pad 12 includes inner ring pad 121, outer ring pad 122,
There is the region between the mutual radial ribs 123 of connection, radial ribs 123 to constitute axially between inner ring pad 121, outer ring pad 122
Communication paths and with the path on shell 11 postpone it is corresponding arrangement, sealing ventilation diaphragm 20 be located at outer ring 111 inner side end and
Separated between valve pad 12 and by path.The face that shell 11, valve pad 12 are contacted with sealing ventilation diaphragm 20 is inner side end, rib
Axial communication paths are constituted between 123, are postponed corresponding arrangement, arrangement between shell 11 and the path of valve pad 12 with the path of shell 11
Sealing breathable film 20 plays a protective role to it, it is ensured that safe valve body 10 is normal when being arranged on the devices such as casing, pipeline
Work.
The described middle part of outer ring 111 is stepped hole, and large aperture section is located at the inner side end of outer ring 111, and connecting pole 112 is
Step Shaft, the enlarged diameter section of connecting pole 112 and the corresponding arrangement of the small-bore section axial location of outer ring 111, connecting pole 112 it is small directly
Footpath section is extended to outside the inner side end of outer ring 111 and passed through from the inner ring pad 121 of valve pad 12, the minor diameter of connecting pole 112
End coordinates provided with internal thread hole with screw 30 to be connected with tank wall or tube wall 40, in the step surface, outer ring 111 on connecting pole 112
Step surface and the inner side end edge of meeting stile 113 concordantly constitute diaphragm support face A, inner ring pad 121, the outer ring pad of valve pad 12
122 inner side end concordantly constitutes diaphragm seal face B, sealing ventilation diaphragm 20 be located at diaphragm support face A and diaphragm seal face B it
Between.Shell 11 and valve pad 12, which respectively constitute diaphragm support face A and diaphragm seal face B, is used to be fixedly clamped sealing ventilation diaphragm 20 in fact
Now ventilation, waterproof, screw 30 is connected through tank wall or tube wall 40 with the internal thread hole on connecting pole 112 makes safety valve be fixed on case
On wall or tube wall 40.
The inner side end of the outer ring pad 122 of described valve pad 12 includes inside and outside flange collar 124,125, interior flange collar 124 and evagination
