The bottom of valve body is bolted with valve gap, and valve gap form bonnet central bore and be positioned at valve upper part of the cover valve gap back-up ring, acid filtering film is placed in valve gap and keeps off bonnet central bore, and acid filtering film is clamped between valve gap back-up ring and the lower surface of valve body;
Rubber bodies is made up of cap portion, lug boss and plunger portion, the top in cap portion forms lug boss, cap portion forms elasticity trim ring, the maximum gauge of lug boss is less than the diameter in cap portion, the bottom in cap portion forms plunger portion, plunger portion forms the venting channels running through whole plunger portion, the space that venting channels is formed with cap portion and elasticity trim ring communicates, and plunger portion sleeve is in valve body centre bore;
Adjusting knob forms by knob cylindrical body forming knob depression bar, knob cylindrical body forms knob steam vent;
The bottom of elasticity trim ring press against centre bore step, and adjusting knob is screwed onto on valve body, and the top, bottom of knob depression bar press against lug boss, and valve body external thread bolt connection, on storage battery plastics exhaust nozzle, is clamped with O RunddichtringO between valve body and storage battery plastics exhaust nozzle.
Described venting channels is the groove that plunger portion forms out.
Described knob cylindrical body forms at least two knob steam vents.
Beneficial effect of the present invention is:
1, it solves by adjustment knob the problem that existing product cannot adjust storage battery exhaust opening pressure value, it is by the design to rubber bodies simultaneously, ensure the better performance of caoutchouc elasticity, the difference making storage battery be vented unlatching value and close value reduces further, stabilize pressure in battery-operated, extend the useful life of storage battery.
2, the acid filtering film of existing safety valve designs the end in rubber valve exhaust, and whole like this rubber valve is in concentrated acid environment for a long time, can accelerate the aging of rubber valve.The design of acid filtering film in the front end of rubber bodies, ensures not contain acidic materials by the gas of rubber bodies, extends the useful life of rubber bodies, thus ensure that the useful life of storage battery by this patent product.

Embodiment:
Embodiment 1: see shown in Fig. 1 to 4, adjustable die mould storage battery safety valve, comprises storage battery plastics exhaust nozzle 1, valve body 2 forms valve body centre bore 21 and valve body external screw thread 22, and valve body centre bore 21 is for having the hole of centre bore step 211;
The bottom of valve body 2 is bolted with valve gap 3, and valve gap 3 forms bonnet central bore 31 and the valve gap back-up ring 32 being positioned at valve gap 3 top, acid filtering film 4 is placed in valve gap 3 and keeps off bonnet central bore 31, and acid filtering film 4 is clamped between the lower surface of valve gap back-up ring 32 and valve body 2;
Rubber bodies 5 is made up of cap portion 51, lug boss 52 and plunger portion 53, the top in cap portion 51 forms lug boss 52, cap portion 51 forms elasticity trim ring 511, the maximum gauge of lug boss 52 is less than the diameter in cap portion 51, the bottom in cap portion 51 forms plunger portion 53, plunger portion 53 forms the venting channels 531 running through whole plunger portion, the space that venting channels 531 is formed with cap portion 51 and elasticity trim ring 511 communicates, and plunger portion 53 sleeve is in valve body centre bore 21;
Adjusting knob 6 forms by knob cylindrical body 61 forming knob depression bar 62, knob cylindrical body 61 forms knob steam vent 611;
The bottom of elasticity trim ring 511 press against centre bore step 211, adjusting knob 6 is screwed onto on valve body 2, the top, bottom of knob depression bar 62 press against lug boss 52, and valve body external screw thread 22 is screwed onto on storage battery plastics exhaust nozzle 1, is clamped with O RunddichtringO 7 between valve body 2 and storage battery plastics exhaust nozzle 1.
