Description
Technical field
The utility model relates to a kind of valve-regulated relief cock of storage battery, especially spiral shell is provided with the explosion-protection equipment that burst disk is housed on the fluid injection tube of a kind of storage battery of finger, if just in case take place that hydrogen is quick-fried can be pressed against the stopper upper air-vent with the burst disk in the stopper by the pressure of the quick-fried generation of hydrogen, follow the footpath storage battery that ignites to avoid the quick-fried flame of hydrogen.
Background technology
General vapour, the employed storage battery of locomotive owing to adopt the mode of chemical reaction to produce electric power, and can produce hydrogen in chemical reaction process, and hydrogen system constantly produces, and therefore hydrogen must be discharged, and meet accident to avoid hoarding in storage battery.
Consult Fig. 4, Fig. 5, stopper b on the known liquid injection port a1 that is installed in storage battery a, lie in a bottom surface and convex with the stopper b of a hollow pipe b1, be provided with an air vent hole b2 in this hollow pipe side, and the end face at stopper b is provided with an air-vent b3, this air-vent b3 is communicated with air vent hole b2, and is set with a leakproof film C in the hollow pipe b1 of stopper b.
When storage battery a is produced electric power by chemical reaction, the hydrogen that is produced in the course of reaction must be by the air vent hole b2 of liquid injection port by the hollow pipe b1 of stopper b, and the air-vent b3 by stopper b discharges again, so can discharge the hydrogen that storage battery a is produced.Right hydrogen is the deflagrability gas of low ignition point, and storage battery is installed in the engine chamber of automobile usually, and the very high improper ventilation again of the temperature of engine chamber, if hydrogen condenses in engine chamber, and temperature then can produce the quick-fried situation of hydrogen when reaching the burning-point of hydrogen; And the air-vent b3 of the stopper b of storage battery a is communicated with air vent hole b2, and the flame that makes blast be produced can follow the footpath and burn to storage battery a inside, thereby ignites storage battery a easily.
Summary of the invention
The inventor has all disappearances of above-mentioned kind thoughts on the stopper b on the known storage battery a, thereby sets about design, designs the utility model eventually.
Main purpose of the present utility model, aim to provide that spiral shell is provided with the explosion-protection equipment that burst disk is housed on a kind of fluid injection tube of storage battery, if just in case take place that hydrogen is quick-fried can be pressed against the stopper upper air-vent with the burst disk in the stopper by the pressure of the quick-fried generation of hydrogen, follow the footpath storage battery that ignites to avoid the quick-fried flame of hydrogen.
Another purpose of the present utility model then is enclosed in interior and can be changed into water by the valve of explosion-protection equipment at the hydrogen that provides a kind of storage battery to produce and oxygen and returns in the electrolyte, to increase its useful life.
The utility model adopts technical scheme as described below for achieving the above object, a kind of valve-regulated relief cock of storage battery, mainly lie in a storage battery and be provided with a plurality of liquid injection port with negative thread, spiral shell is established an explosion-protection equipment that is set with the leakproof film on this liquid injection port, this explosion-protection equipment lies in and is provided with a fluid injection tube in the cylindrical shell, be provided with a plurality of pressure regulation openings in this fluid injection tube top, and one valve is housed in this fluid injection jacket casing, the stopper that has steam vent again in cylinder top installing one, and the bottom surface of this stopper has ring in, and this inner ring sleeve is outside valve, make between this interior ring and the valve to have a gap, in this, insert the burst disk of an activity again between ring and the valve.
According to above-mentioned structure, because the fluid injection tube top of this storage battery is provided with a plurality of pressure regulation openings, the hydrogen that storage battery is produced must slowly be discharged via valve on the dividing plate of stopper and steam vent by the pressure regulation opening, if just in case it is quick-fried that hydrogen takes place, by the quick-fried pressure that produces of hydrogen the burst disk in the stopper is pressed against valve on the dividing plate, to avoid the quick-fried flame of hydrogen to follow the footpath storage battery that ignites: and in the hydrogen that storage battery was produced and oxygen is enclosed in by valve, return in the electrolyte and can change into water, to increase its useful life.

Embodiment
See also Fig. 1, Fig. 2, shown in Figure 3, the utility model mainly lies in a storage battery 1 and is provided with a plurality of liquid injection port 11 with negative thread 11a, spiral shell is established an explosion-protection equipment 3 that is set with leakproof film 2 on this liquid injection port 11, this explosion-protection equipment 3 lies in a cylindrical shell 31 bottoms and is provided with a pin thread 31a, on the negative thread 11a with the liquid injection port 11 that cylindrical shell 31 is arranged in storage battery 1, in cylindrical shell 31, be provided with a fluid injection tube 32 again, be provided with a plurality of pressure regulation opening 32a in these fluid injection tube 32 tops, and be set with a valve 33 in this fluid injection tube 32, the stopper 34 that has steam vent 341 again in cylindrical shell 31 tops installing one, and the bottom surface of this stopper 34 has ring 342 in, and should be enclosed within outside the valve 33 by interior ring 342, make between this interior ring 342 and the valve 33 to have a gap 35, in this, insert the burst disk 36 of an activity again between ring 432 and the valve 33.
According to above-mentioned structure, when storage battery 1 is produced electric power by chemical reaction, the hydrogen that is produced in the course of reaction must be discharged by the pressure regulation opening 32a of fluid injection tube 32, and the burst disk 36 of device in the interior ring 342 of stopper 34 only is pressed against on the valve 33 by the deadweight of itself, and this burst disk 36 is thin little, storage battery 1 is a closed container again, and hydrogen constantly produces and is condensed into one little pressure, and can thus little pressure with burst disk 36 upwards ejections, make that hydrogen can be by the gap 35 between valve 33 and the interior ring 342, and discharge, thereby has the effect of pressure regulation by the steam vent 341 of stopper 34.
Moreover hydrogen that is produced in this storage battery 1 power generation process and oxygen is because of in being enclosed in by valve 33, thereby can change into water and return in the electrolyte, to increase its useful life.
If just in case it is quick-fried that hydrogen takes place, hydrogen is quick-fried to be produced pressure moment is pressed against steam vent 341 bottoms of stopper 34 with the burst disk 36 in the stopper 34, follows the footpath storage battery that ignites with the flame of avoiding exploding, thereby preferable protective and fail safe are arranged.
