Summary of the invention

Technical problem to be solved in the utility model is the safety valve of a kind of new sealed lead acid storage battery of design, after this safety valve installs on the sealed lead acid storage battery, guaranteeing under cell sealing and the prerequisite safe in utilization, can safeguard the sealing lead acid accumulator when needed, safety valve itself also can keep in repair as required, to cut the waste, to save cost.

The sealed lead acid storage battery the safeguarded safety valve that the utility model provides is made of valve body, sealing ring, filter acid film, and valve body is an overall structure, has steam vent on the valve body and filters the acid mouth, and filter acid film is loaded in the filter acid mouth.Improvements are that valve body is made of valve top, valve pocket groove, valve housing, seal groove, threaded body, and except that the valve top is six squares, all the other each several parts are column type, and the inside that valve pushes up with the lower part is up-small and down-big step blind hole structure; Suit one valve pocket on the valve pocket groove; Steam vent is opened on the post jamb of valve pocket groove; Ring set is on seal groove.

The sealed lead acid storage battery the safeguarded safety valve that the utility model provides, the number of steam vent are more than two, and are uniformly distributed on the post jamb of seal groove.

Above technical scheme, the setting owing to threaded body on the valve body and six square valves top makes the utility model can guarantee that not only its installation on the sealed lead acid storage battery housing is firm, and easily dismounting.When the moisture of inside battery when exhaust reduces to the operate as normal that influences battery repeatedly, just can at an easy rate the utility model be unloaded, after battery safeguarded, promptly adds an amount of water, again the utility model is loaded onto again, the battery that will thoroughly discard before making continues to use about 6 months under the state of sealing, safety, thus the purpose of the saving cost of having realized cutting the waste.In addition, when valve pocket of the present utility model, sealing ring, filter acid film can not satisfy instructions for use because of wearing out, also can change; Even whole safety valve all can change in the same model scope, thereby further realized the maintenance to safety valve itself.The utility model steam vent is more than two and equally distributed design, has improved the unobstructed property of exhaust.Valve pocket is set in the valve pocket groove, and is firm and tight, and it can be changed in addition, and this is just guaranteeing on himself well behaved basis, and then provides further assurance for the unobstructed property of exhaust.And the convertibility of sealing ring and be set in design on the seal groove has guaranteed that then its sealing function brings into play fully effectively, thereby provides reliable guarantee for fail safe of the present utility model and sealing.Of the present utility model simple in structure, manufacturing and use are all very convenient, obviously also are much progresses.
