Description
Technical field
The utility model relates to a kind of accumulator protection valve, especially for a kind of safety valve of valve-control sealed lead acid battery.
Background technology
Safety valve is a vitals of valve-control sealed lead acid battery.Early safety valve valve gap and valve seat juncture are plug-in type.This juncture is easy to open, and valve gap easily loses, and acid mist proof sheet is fragile, causes filtering the acid mist afunction, influences the safety valve life-span.In addition, valve gap is opened, and valve is also just opened thereupon, easily causes battery to be damaged.For addressing this problem, existent method roughly is divided into two kinds: the one, adopt the bayonet type valve bonnet, and valve bonnet is divided into two, and one is loam cake, and one is guard shield.This safety valve structure is loose, uses inconvenience, and has fit clearance, and valve gap is still opened easily and lost, thereby influences the life-span and the environmental protection of valve; Another kind method is to adopt the integral type valve bonnet, becomes bayonet type to engage with valve seat.Though the reasonable the problems referred to above that solved of this method need in the integral type valve bonnet to be connected by the cannelure on special ratchet and the valve seat, the processing of ratchet and cannelure has increased manufacture difficulty and manufacturing cost again greatly.
Summary of the invention
The purpose of this utility model provides a kind of above-mentioned defective that overcomes, and is simple in structure, is easy to install and make a kind of lead-acid accumulator protection valve with low cost.
The technical solution adopted in the utility model is: a kind of lead-acid accumulator protection valve, form by protection cover plate and valve seat, valve seat is assembled by compressing tablet, gland, two-layer filter acid film, safety valve body, Capsule, base plate, O-ring seal, it is characterized in that protecting cover plate to be down cup-shaped structure, inside top has reinforcement, the medial surface bottom margin has claw, and claw is corresponding along boss with the valve body top sides; The protection cover plate is that reverse buckling type is connected with safety valve body, and the protection cover plate is relative to can freely rotating with valve seat; Gland is a cylindrical structure, the internal chamber wall tight fit of its outer wall and safety valve body, and the gland intracavity bottom has the reducing platform, and reducing platform top has upper strata filter acid film and compressing tablet, the internal chamber wall tight fit of upper strata filter acid film and compressing tablet and gland successively.
Described safety valve body top sides is smooth chamfering along boss, and the chamfering height of projection is corresponding with the claw height of projection on the protection cover plate.
The reinforcement number of described protection cover plate inside top is no less than 3, and the claw number of medial surface bottom margin is no less than 3.
A kind of lead-acid accumulator protection valve, it is characterized in that protecting the cover plate inside top that 3 angles are arranged is 120 ° reinforcement, the medial surface bottom margin is evenly distributed with 3 claws; The safety valve body top sides is along there being 45 ° of smooth chamferings, and the chamfering height of projection is corresponding with the claw height of projection on the protection cover plate; The protection cover plate is that reverse buckling type is connected with safety valve body, and the protection cover plate can freely rotate along the chamfering rib relative to valve seat.
The beneficial effects of the utility model are: protection cover plate inside top has reinforcement, both can improve the intensity of cover plate, can make between cover plate and valve body again and reserve the gap, and gas can precipitate into outside the valve smoothly when making the safety valve pressure release; The medial surface bottom margin has the protrusion type claw, the safety valve body top chamfer, make the valve body upper outer become a smooth rib of big gradient, the claw of protection cover plate can be slided into like a cork under the smooth rib of valve body, install easily manufactured, and this reverse buckling type connected mode is difficult for taking off after the protection cover plate is installed, and has guaranteed the fail safe of safety valve effectively; Valve body adopts smooth the connection with the protection cover plate in addition; the protection cover plate is freely rotated on valve body, and can not drive the rotation of valve seat, protect being connected between safety valve and the battery cover effectively; help battery and keep good sealing property, extend the life of a cell.The safety valve component structural is simply compact, is difficult for losing, and also the simple structure of safety valve and reverse buckling type connected mode, be easy to again install and make, and with low cost.
