Fig. 2 is the application's perspective view in one embodiment of safety valve;
Fig. 3 is the application's cutaway view in another embodiment of safety valve.
Embodiment
Below by embodiment, by reference to the accompanying drawings the application is described in further detail.
Embodiment mono-:
As shown in Figure 1, the application's safety valve overcoat 10, its a kind of execution mode, overcoat 10 has inner chamber 11, inner chamber 11 upper ends are provided with opening 12, inner chamber 11 lower ends are closed, and inner chamber 11 lower ends are provided with air vent hole 13 and return port 14, and air vent hole 13 in the vertical directions are higher than return port 14, overcoat 10 is provided with external screw thread 15, overcoat 10 upper ends are provided with outer 16, and safety valve overcoat 10 also comprises that the first through hole 17, the first through holes 17 that are arranged on external screw thread 15 are communicated with inner chamber 11.
In one embodiment, the first through hole 17 is slotted eye.In another embodiment, the first through hole 17 is circular hole.
Between external screw thread 17 and outer 16, also can be provided with for the sealing ring installation position 18 of sealing ring is installed.
Embodiment bis-:
As Fig. 2, shown in Fig. 3, the application's safety valve, its a kind of execution mode, comprise air filter piece 20, be nested with 30 and safety valve overcoat 10, safety valve overcoat 10 has inner chamber 11, inner chamber 11 upper ends are provided with opening 12 and lower end is closed, inner chamber 11 lower ends are provided with air vent hole 13 and return port 14, air vent hole 13 in the vertical directions are higher than return port 14, safety valve overcoat 10 is provided with external screw thread 15, safety valve overcoat 10 upper ends are provided with outer 16, being nested with 30 is arranged on opening 12, air filter piece 20 is arranged on and is nested with on 30, safety valve overcoat 10 also comprises the first through hole 17 being arranged on external screw thread 15, the first through hole 17 is communicated with inner chamber 11.
In one embodiment, the first through hole 17 is slotted eye.In another embodiment, the first through hole 17 is circular hole.
The application's safety valve, can also comprise sealing ring 40, and sealing ring 40 is set on safety valve overcoat 10.In one embodiment, between external screw thread 15 and outer 16, also can be provided with for the sealing ring installation position 18 of sealing ring 40 is installed.
In one embodiment, being nested with 30 lower ends has and is horizontally disposed with the second through hole 31.
Before charging, battery acid liquid level is lower than air vent hole 13 and acid solution return port 14, when being charged to the regular hour, in cell negative terminal, there is chemical reaction, can produce certain gas and steam, if be at this moment nested with 30 and the passage of air filter piece 20 can not arrange the gas of a certain amount of release, can make gas stay in single lattice, pressure in single lattice is strengthened, and at this moment the acid solution face in single lattice will rise.If rise to air vent hole 13 and acid solution return port 14 places, make gas more be difficult to discharge, gas passage only has two holes below, now be plugged, gas can only be discharged few part from liquid, gas in single lattice is detained in a large number, and acid solution rises and flows out safety valve and occur battery bulging phenomenon.The application increases by the first through hole 17 in safety valve overcoat side, can reduce the generation of above-mentioned phenomenon.Even if acid solution rises, air vent hole below 13 and acid solution return port 14 are blocked, gas can also continue to discharge in the first logical 17 holes that newly add.Even if be nested with 30 and the passage of air filter piece 20 can not arrange a certain amount of gas and make acid solution increase, can not make single lattice acid solution form gas be difficult for discharging phenomenon yet, because gas is still constantly from the interior outside discharge of the first through hole 17, cell negative terminal internal pressure reduces, so it is very high that acid solution face also can not rise, can there is not bulging phenomenon in battery yet.Because being charged to the regular hour, the gas that the acid solution in single lattice produces will reach poised state, and liquid level rises to certain height and just can not rise, so can also increase a certain amount of acid solution for extending the useful life of battery.
Above content is the further description of the application being done in conjunction with concrete execution mode, can not assert that the application's concrete enforcement is confined to these explanations.For the application person of an ordinary skill in the technical field, not departing under the prerequisite of the application's design, can also make some simple deduction or replace.
