Abstract
The utility model discloses an explosion-proof safety valve for a storage battery. The explosion-proof safety valve comprises a valve body, an adjusting nut, a pressure spring, a piston, a sealing ring, a pin and a pin spring, wherein the adjusting nut is arranged at the rear end of the valve body and is connected with one end of the pressure spring which is positioned in the valve body; the other end of the pressure spring is connected with one end of the piston; the other end of the piston is connected with the sealing ring; the pin spring is arranged in the valve body and is fixedly connected with the pin; the upper part of the piston is provided with a pit which corresponds to the pin; the inner side of the front end of the valve body is provided with a first channel; the first channel is communicated with a cavity where the pin is positioned through a second channel; a through hole is formed on the sealing ring; and a pressure relief hole which corresponds to the through hole is formed on the valve body. According to the explosion-proof safety valve, the inner pressure of the storage battery can be effectively controlled, the storage battery is prevented from being exploded due to extremely high inner pressure, and the explosion-proof safety valve is convenient to use and high in practicality.
Description
Technical field
The utility model relates to a kind of secondary battery anti-explosion safety valve.
Background technology
Storage battery is with low cost because of it, stable performance, advantage such as easy to use obtain using very widely at daily and industrial circle.Storage battery is the inner gas that produces in the process of using, and causes cell internal pressure constantly to raise, and accumulator pole might be blasted.Accumulator explosion can produce very serious consequence in a lot of hazardous environments.Therefore, the explosion-proof performance of storage battery is very important performance index.
At present; The explosion precaution of storage battery the most commonly is provided with the secondary battery anti-explosion cover plate; On this cover plate, process vulnerable area through various processes, when the pressure of inside battery raises and when surpassing the pressure that vulnerable area can bear, the vulnerable area fracture; Cell internal pressure is reduced rapidly, avoid blasting.Though such method can improve the secondary battery anti-explosion performance simply and effectively, this is the type self-destroyed explosion-proof methods of a kind of parts, and promptly an explosion-proof covering board can only use once, causes waste and use not convenient of material, and practicality is not good enough.
The utility model content
The utility model technical problem to be solved is that secondary battery anti-explosion safety valve a kind of easy to use, practical is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of secondary battery anti-explosion safety valve, comprise valve body, adjusting nut, compression spring, piston, sealing ring, latch and latch spring, and said adjusting nut is contained in the rear end of valve body; And link to each other with an end of the compression spring that is positioned at valve body; The other end of said compression spring links to each other with an end of piston, and the other end of said piston links to each other with sealing ring, and said latch spring is contained in the valve body; And be fixedly connected with latch; The top of said piston is provided with and the corresponding pit of latch, and the front end inboard of said valve body is provided with first passage, and said first passage is communicated with latch place cavity through second channel; Said sealing ring is provided with through hole, and said valve body is provided with and the corresponding relief hole of through hole.
Further, said sealing ring is a rubber seal.
The secondary battery anti-explosion safety valve of the utility model is a unidirectional valve.During use, it is installed on the cover plate of storage battery, airflow direction is flowed to outside by internal, have the function that discharges internal pressure and sealing.
Operation principle: in the use; The gas that internal produces successively flows into first passage and second channel; When the pressure of internal reaches a certain setup pressure value (according to explosion-proof demand), gas promotes sealing ring and moves to right, and sealing ring drives the Piston Compression compression spring; When the through hole of sealing ring communicates with the relief hole of valve body; Gas begins to leak, and simultaneously latch is displaced downwardly in the pit of piston (gas is to the active force of the latch restoring force greater than latch spring) seized piston under the effect of gas pressure, and gas continues to leak; When the pressure of internal drops to a certain setup pressure value (according to explosion-proof demand); Latch moves (gas is to the active force of the latch restoring force less than latch spring) release plunger under the effect of latch spring restoring force; Piston promotes sealing ring and moves to left under the effect of compression spring, seal relief hole.
Compared with prior art, the utility model can not only effectively be controlled the internal pressure of storage battery, prevents that storage battery from blasting because of internal pressure is too high, can also avoid the waste of material of prior art, uses also more conveniently, and practicality is stronger; Particularly importantly, the utility model can make storage battery can satisfy different explosion-proof demands through the maximum pressure of adjusting nut control internal, further improves the explosion-proof performance and the Practical Performance of storage battery.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is an installation diagram embodiment illustrated in fig. 1.
Specific embodiments
Below in conjunction with accompanying drawing and embodiment the utility model is described further
.
With reference to Fig. 1, present embodiment comprises valve body 1, adjusting nut 5, compression spring 6, piston 7, sealing ring 2, latch 3 and latch spring 4, and said adjusting nut 5 is contained in the rear end of valve body 1; And link to each other with an end of the compression spring that is positioned at valve body 16; The other end of said compression spring 6 links to each other with an end of piston 7, and the other end of said piston 7 links to each other with sealing ring 2, and said latch spring 4 is contained in the valve body 1; And be fixedly connected with latch 3; The top of said piston 7 is provided with and latch 3 corresponding pits 8, and the front end inboard of said valve body 1 is provided with first passage 9, and said first passage 9 is communicated with latch 3 place cavitys through second channel 10; Said sealing ring 2 is provided with through hole 11, and said valve body 1 is provided with and through hole 11 corresponding relief holes 12.
Said sealing ring is a rubber seal.Certainly, also can process by the material of other corrosion resistance.
Said piston is processed by stainless steel.
The secondary battery anti-explosion safety valve of present embodiment is a unidirectional valve.During use, it is installed on the cover plate 14 of storage battery 13 (referring to Fig. 2), airflow direction is flowed to outside by internal, have the function that discharges internal pressure and sealing.
Operation principle: in the use; The storage battery 13 inner gases that produce successively flow into first passage 9 and second channel 10; When storage battery 13 pressure inside reach the pressure value P of setting (this force value should be confirmed according to the concrete condition of use battery), gas promotes sealing ring 2 and moves to right, and sealing ring 2 drives piston 7 compression pressure springs 6; When the through hole 11 of sealing ring 2 communicates with the relief hole 12 of valve body 1; Gas begins to leak, and simultaneously latch 3 is displaced downwardly in the pit 8 of piston 7 (gas is to the active force of the latch restoring force greater than latch spring) seized piston 7 under the effect of gas pressure, and gas continues to leak; When storage battery 13 pressure inside drop to pressure value P; Latch 3 moves (gas is to the active force of the latch restoring force less than latch spring) release plunger 7 under the effect of latch spring 4 restoring forces; Piston 7 promotes sealing ring 2 and moves to left under the effect of compression spring 6, seal relief hole 12.
