Abstract
The utility model relates to a pressure-limiting valve for a start-stop storage battery. A safety valve for the start-stop storage battery comprises a valve hole and a valve body, wherein the valve hole is formed in the upper part of the case of the storage battery; the valve body is matched with the valve hole; the valve hole is a cylindrical inner cavity; an annular boss is arranged at the bottom of the valve hole; the outer wall of the valve body takes the shape of annular sawteeth; a plurality of circles of annular convex teeth are formed on the outer wall of the valve body; the bottom of the valve body is closely clung to the annular boss of the valve hole to form line contact; the annular convex teeth on the outer wall of the valve body are closely clung to the wall of the valve hole to form line contact. When the safety valve is opened, gas in the safety valve is sealed through the multiple line contacts so as to ensure air pressure accuracy, and atmospheric pressure generated instantaneously can be buffered; the pressure range during opening and closing is 25-30 KPa, the service life is prolonged by one time when compared with that of the conventional bonnet, and the phenomenon of swelling deformation of the storage battery, or drying caused by too fast water loss is completely avoided.
Description
Technical field
The utility model relates to a kind of start and stop storage battery pressure limiting valve, is specifically related to a kind of start and stop storage battery safety valve.
Background technology
Car is in the time of the green lights such as red light crossing, and out of service with oil turbine, car is to provide power with start and stop battery; In the time waiting until green light, with oil turbine or out of service, it is to provide power with start and stop battery that car continues; Bring into operation with oil turbine after 2 minutes when travelling, then start and stop battery stops providing power; By the time next crossing starts again to provide power with start and stop battery, stops with oil system.Battery is heavy-current discharge for car provides electric energy to convert power to, cross crossing after 2 minutes with oil system start generating be the large electric current quick charge of start and stop battery, this large current charge electric discharge so repeatedly, average stop reaching every day 20～50 this, namely bonnet repeatedly open, closure, this just requires, and the sensitivity of bonnet wants high, resilience will be got well, the cushion effect of gas is eager to excel.
Conventional Capsule: referring to Fig. 1, the crown of bonnet and cap sidewall are plane.Its shortcoming: bonnet top, the adjacent valve opening oral area of bonnet inwall and outer wall, bonnet is opened not prompt enough, the easy bulging distortion of battery; Resilience is poor, and quick charge finishes bonnet closes not in time, and the easy dehydration of battery is dry.The too large 12～40KPa of pressure limit that conventional bonnet opens and closes, can not effectively meet the performance requirement of electronic start and stop battery.
Utility model content
The purpose of this utility model is the problem and shortage for above-mentioned existence, and a kind of flexibility ratio and elastic start and stop storage battery safety valve that improves valve body is provided.
For achieving the above object, the technical scheme of taking is:
A kind of start and stop storage battery safety valve, comprise the valve body that is arranged on the valve opening on accumulator housing top and mates with valve opening, described valve opening is cylindrical cavity, valve opening bottom is provided with annular boss, described valve outer wall zigzag form multiple tracks annular double wedge ringwise, valve body bottom is closely adjacent to and forms line with the annular boss of valve opening and contacts, and the annular double wedge of valve outer wall is closely adjacent to and forms line with valve opening hole wall and contacts.
Described valve opening adopts ABS material to make, and valve body adopts elastomeric material to make.
Described annular double wedge is 2 ~ 4 roads.
Adopt technique scheme, obtained beneficial effect is:
The unlatching of the utility model valve, its inner gas, through the sealing of multiple tracks line contact, is guaranteed air pressure accuracy, can cushion the atmospheric pressure that moment produces; Also be the contact of multiple tracks line for closing of valve, so safety factor improves 4 times; Because valve body is cylindricality zigzag, frequent switch keeps good resilience and sensitivity for a long time.Open and the too large 25～30KPa of the pressure limit of closing, double useful life than conventional bonnet, avoids the distortion of battery bulging or the too fast dry-out of dehydration completely.
Brief description of the drawings
Fig. 1 is the structural representation of existing storage battery pressure limiting valve.
Fig. 2 is the structural representation of the utility model valve opening.
Fig. 3 is the structural representation of the utility model valve body.
Fig. 4 is the utility model valve body and the structural representation coordinating of valve opening.
Sequence number in figure: 1 is that housing, 2 is that valve opening, 3 is that valve body, 4 is that annular boss, 5 is annular double wedge.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
Referring to Fig. 1-Fig. 4, a kind of start and stop storage battery safety valve, comprise the valve body 3 that is arranged on the valve opening 2 on accumulator housing 1 top and mates with valve opening 2, described valve opening 2 is cylindrical cavity, valve opening 2 bottoms are provided with annular boss 4, described valve body 3 outer walls zigzag form multiple tracks annular double wedge 5 ringwise, valve body 3 bottoms are closely adjacent to and form line with the annular boss 4 of valve opening 2 and contact, the annular double wedge 5 of valve body 3 outer walls is closely adjacent to and forms line with valve opening 2 hole walls and contacts, described valve opening 2 adopts ABS material to make, valve body 3 adopts elastomeric material to make, described annular double wedge 5 is 2 ~ 4 roads.
The unlatching of the utility model valve, its inner gas, through the sealing of multiple tracks line contact, is guaranteed air pressure accuracy, can cushion the atmospheric pressure that moment produces; Also be the contact of multiple tracks line for closing of valve, so safety factor improves 4 times; Because valve body is cylindricality zigzag, frequent switch keeps good resilience and sensitivity for a long time.Open and the too large 25～30KPa of the pressure limit of closing, double useful life than conventional bonnet, avoids the distortion of battery bulging or the too fast dry-out of dehydration completely.
