Abstract
The utility model provides a valve-controlled sealed lead-acid battery with the improved performance of a safety valve. By improving the structure of the safety valve, a screw thread sealing structure (12) and a condensation trough (13) are added on a safety valve seat (6), a sealing lip (11) is added on a gum cap, on the upper side of which an explosion-proof sealing cover plate (4) is added, and a protective cover plate (3) is add on the upper side of the safety valve. The utility model resolves the defect of the exudate and adhesion of the safety valve, which is caused by the bad sealing performance of previous batteries, as a result, the use of the utility model is more safe, and the opening and closing of the valve is more sensitive.
Description
The utility model relates to valve-control sealed lead acid battery, relate more specifically to a kind of valve-control sealed lead acid battery safety valve, this safety valve can effectively guarantee valve-control sealed lead acid battery to safety valve open and close valve pressure-sensitivity and prevent and the requirement of seat adhesion, and guarantees valve-control sealed lead acid battery seal request to the safety valve position when horizontal placement is used.
At present, the structure of valve-control sealed lead acid battery safety valve has two kinds.A kind of is that emergency valve seat and battery cover are one, Capsule is covered form easy safety valve structure then on valve seat; Another is emergency valve seat and battery cover split, adopts the projective table type structure to connect, because of having installation, transposing and some other advantages of being convenient to safety valve with preceding a kind of comparing, so adopted more.But a kind of safety valve in back in use also has many unreasonable parts: it is bad that (1) projective table type syndeton connects effect, and tightness is difficult to control, threads off easily in the use, make safety valve easing, form the space, the inside battery acid mist overflows easily, causes the battery dehydration; (2) safety valve opens and closes insensitively, can not guarantee the compound needed pressure of inside battery oxygen, and the performance of battery is impacted; (3) the easy and plastics adhesion of safety valve gum cap.
The purpose of this utility model provides a kind of above-mentioned defective that can overcome, and its safety valve has the valve-control sealed lead acid battery of seepage-proof liquid, anti-adhesion, good seal performance, open and close valve sensitivity.
The utility model is realized in the following way: this type valve-control sealed lead acid battery safety valve is made up of valve seat, Capsule, filter acid film, compressing tablet, sealed cover slip, protection cover plate, rubber seal etc.Safety valve and battery cover adopt fine thread to be connected and with the sealing rubber ring sealing, and this structure can prevent the gas leakage problem that produces because of safety valve easing in the battery use afterwards, can horizontally-arrangedly use with the assurance battery.In order to prevent that this type storage battery from having the acid mist benefit to go out, in safety valve, be provided with double-deck filter acid film and filter acid gas, one deck filter acid film can prevent overflowing of acid mist in the upstream of gas passage, and energy absorption portion acid mist; One deck filter acid film can fall the acid mist of remnants and its moisture sorption in the downstream of gas passage in addition.Can acid mist not overflowed like this, reduce dehydration.Around gas passage, increase the condensate tank(trap) structure, this structure is the long and narrow space of an annular, make and effectively to be cooled to liquid when hot gas arrives herein in the battery and to be back in the battery, the electrolyte that has effectively prevented inside battery is with the discharge of gas form from the safety valve position, prevent battery too early drying up in the operating period, prolonged the useful life of battery.Capsule adopts line style contact seal, has replaced traditional face seal, and has adopted inside and outside each three seals procheilon structure, makes storage battery open and close valve in the useful life of safety valve sensitive more, to guarantee the serviceability of storage battery.One sealed cover slip is arranged on Capsule, this sealed cover slip can not only play sealing function, the explosion that also can eliminate simultaneously internal storage battery to fail to meet naked light when the hydrogen of combination without repetition overflows and produce plays explosion-proof, has improved the fail safe in the storage battery use.A protection cover plate is arranged in the top of safety valve, and this protection cover plate adopts the buckle-type structure to be connected with valve seat, and the live part of safety valve is placed under the general protection, has avoided owing to because of carelessness or the improper destruction of causing of manual operation.
Owing to adopt such scheme, can obviously solve the leakage problem at storage battery safety valve position when horizontal, and guarantee safety valve open and close valve sensitivity in use, and use easy to adjustly, and make battery structure systematization more, standardization.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the safety valve general structure outline drawing of the utility model embodiment
Fig. 2 is the section of structure of the utility model embodiment
Fig. 3 is the protection cover plate schematic diagram of the utility model embodiment
Fig. 4 is the Capsule schematic diagram of the utility model embodiment
Fig. 5 is the emergency valve seat structure chart of the utility model embodiment
Fig. 6 is the emergency valve seat schematic diagram that generally adopts at present
Among the figure: 1. cell cover 2. safety valves 3. are protected cover plates 4. sealed cover slips 5. rubber seal 6. valve seats 7. filter acid films 8. compressing tablets 9. Capsules 10. filter acid films 11. sealing lips 12. thread seal structures 13. condensate tank(trap)s
Present embodiment has increased thread seal structure (12) and condensate tank(trap) (13) on emergency valve seat (6); on Capsule (9), increased sealing lip (11); on Capsule (9), increased an explosion-proof sealed cover slip (4); on safety valve (2), increased protection cover plate (3), make this type product hermeticity can and security performance significantly improves and open and close valve is sensitiveer.
Claims (2)
1, a kind of valve-control sealed lead acid battery; its safety valve is made up of valve seat (6), Capsule (9), filter acid film (7) and (10), compressing tablet (8), sealed cover slip (4), protection cover plate (3), rubber seal (5) etc.; it is characterized in that on emergency valve seat (6), having increased thread seal structure (12), condensate tank(trap) (13), increased sealing lip (11) on the Capsule (9).
