Described venting channels is the groove forming out in plunger portion.
In described knob cylindrical body, form at least two knob steam vents.
Beneficial effect of the present invention is:
1, it has solved by adjusting knob the problem that existing product cannot be adjusted storage battery exhaust opening pressure value, it is by the design to rubber bodies simultaneously, guarantee the better performance of caoutchouc elasticity, the difference of storage battery exhaust unlatching value and close value is further dwindled, stablized in battery-operated and pressed, extended the useful life of storage battery.
2, the design of the acid filtering film of existing safety valve is at the end of 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.This patent product is the front end in rubber bodies by the design of acid filtering film, guarantees not contain acidic materials by the gas of rubber bodies, has extended the useful life of rubber bodies, thereby has guaranteed the useful life of storage battery.

embodiment:
Embodiment 1: see shown in Fig. 1 to 4, adjustable die mould storage battery safety valve, comprises storage battery plastics exhaust nozzle 1, forms valve body centre bore 21 and valve body external screw thread 22 on valve body 2, 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, forms bonnet central bore 31 and the valve gap back-up ring 32 that is positioned at valve gap 3 tops on valve gap 3, and acid filtering film 4 is placed in valve gap 3 and is keeping off bonnet central bore 31, and acid filtering film 4 is clamped between valve gap back-up ring 32 and the lower surface of valve body 2;
Rubber bodies 5 is comprised of cap portion 51, lug boss 52 and plunger portion 53, the top of cap portion 51 forms lug boss 52, in cap portion 52, form elasticity trim ring 511, the maximum gauge of lug boss 52 is less than the diameter of cap portion 51, the bottom of cap portion 51 forms plunger portion 53, in plunger portion 53, form the venting channels 531 that runs through whole plunger portion, venting channels 531 communicates with the space that cap portion 52 and elasticity trim ring 511 form, and plunger portion 53 sleeves are in valve body centre bore 21;
