Further, described plunger is ambroin plunger.
During use, the present invention is installed on cover plate of storage battery, the present invention has the effect that discharges internal storage battery pressure and sealing, and after battery leaks to staff's signal that gives the alarm.
The present invention is simple in structure, reliable, safe and practical, can effectively control the internal pressure of storage battery, prevents storage battery and explodes because internal pressure is too high, improves battery anti-explosion performance.Avoid the damage of explosion-proof battery cover plate, be conducive to save material, improved the Practical Performance of battery.The present invention can monitor the leak condition of storage battery in real time, and to revealing, processes in time, and security performance is high.
Accompanying drawing explanation
Fig. 1 is one embodiment of the invention structural representation;
Fig. 2 is embodiment illustrated in fig. 1 and battery cap board assembling structure schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
With reference to accompanying drawing, the present embodiment comprises valve body 5, in valve body 5, be provided with plunger 2, plunger 2 both sides cylinders are respectively equipped with wedge shape boss I 9-1, wedge shape boss II 9-2, wedge shape boss I 9-1 end face, wedge shape boss II 9-2 end face contact with plunger 2 both sides cylinders respectively, wedge shape boss I 9-1 outside is provided with wedge I 6-1, wedge shape boss II 9-2 outside is provided with wedge II 6-2, wedge I 6-1 mono-side is provided with spring I 8-1, wedge II 6-2 mono-side is provided with spring II 8-2, and spring I 8-1 and spring II 8-2 end are all fixed on valve body 5 inwalls.
Described plunger 2 upper and lowers are respectively equipped with rubber seal I 3 and rubber seal II 7, are beneficial to strengthen sealing property.
Described rubber seal I 3 and rubber seal II 7 are anti-corrosive rubber seal.
Described plunger 2 is provided with anticreep connecting line 4, and plunger 2 is connected with the cover plate 11 of storage battery 10 by anticreep connecting line 4.
Described wedge I 6-1, wedge II 6-2 are connected with warning circuit by circuit lead I 1-1, circuit lead II 1-2 respectively.
Described wedge I 6-1, wedge II 6-2 are metal wedge.
Described plunger 2 is ambroin plunger.
Before use, on the cover plate 11 of storage battery 10, process air vent hole and threaded connection hole, the storage battery that is beneficial to install the present invention can be monitored explosion-protection equipment.And circuit lead I 1-1, circuit lead II 1-2 are all connected to warning circuit.
When the pressure of storage battery 10 inside raises, the gas push plunger 2 producing moves up, there is relative motion in wedge shape boss I 9-1 and wedge I 6-1, wedge shape boss II 9-2 and wedge II 6-2, but still keep in touch each other, spring I 8-1, spring II 8-2 are squeezed, and wedge I 6-1, wedge II 6-2 are all to two side shiftings.When storage battery 11 inside gas pressure while continue raising, on continuing, moves plunger 2, under gas pressure effect, go out the cover plate 11 of storage battery 10, wedge shape boss I 9-1 and wedge I 6-1 wedge shape contact-making surface come off, and wedge shape boss II 9-2 and wedge II 6-2 wedge shape contact-making surface also come off.Under the effect of the anticreep connecting line 4 being connected at the cover plate 11 with storage battery 10, be conducive to prevent that plunger 2 from going out valve body 5 outsides and losing.
