Abstract
A one-way pressure control valve for valve-controlled sealed lead-acid accumulator features that the valve port is arranged in the internal cavity of valve body, a rubber cap is sleeved on the valve port, an embedded plate and an acid filter plate are arranged above the rubber cap, an acid blocking plate is arranged under the valve port, and a notch is arranged above the valve port. The rubber cap is made of acid-proof elastic material, and the acid filtering sheet is of a porous sheet structure. The utility model discloses can effective control battery internal pressure, the action is nimble, safe and reliable, moreover when exhaust gas, can filter acid mist, prevents that the battery from losing water, extension battery life avoids environmental pollution.
Description
The utility model relates to a kind of control valve or vent valve, especially for the uniaxial pressure control valve of valve-control sealed lead acid battery.
Control valve is a vitals of valve-control sealed lead acid battery, in order to the control cell internal pressure, guarantees cell safety and operate as normal.Early stage vent valve, valve port and cell cover fuse, and Capsule is contained on the valve port.When inner pressure of battery during, realize automatic vent greater than external pressure.Because Capsule material loss of properties on aging, after use a period of time, the cracking pressure of valve increases, even does not open; And because Capsule cooperates unreasonablely with valve port, can not recover fully when closing valve, make the cracking pressure of valve inconsistent, very difficult assurance reappearance.People improved the structure of this valve afterwards, and valve port is connected with cell cover by screw thread or bayonet socket, and has designed a catch above Capsule, the position when being ejected with the restriction Capsule.But this valve only has simple switching function, does not possess the effect of acid-proof, filtration, can not prevent the battery dehydration, influences battery useful life.
The purpose of this utility model is to provide a kind of can control cell internal pressure automatically, can filter acid mist again, prevents the A One-Way Pressure Control Valve For Vrla Battery of battery dehydration.
The technical solution of the utility model is: this control valve comprises valve body, valve gap, sealing ring, valve port, Capsule, embedded piece, improvements are that valve port and embedded piece are arranged in the body cavity, Capsule is sleeved on the valve port, both become matched in clearance, Capsule adopts the acid-proof elastomeric material, gapped between its upper surface and the embedded piece, the embedded piece top is provided with filter acid film, and this filter acid film is a porous laminated structure.
As further improvement of the utility model, below, valve port inside is provided with acid-blocking piece, and this acid-blocking piece can be designed to the two-layer semi-circular tongues that is oppositely arranged; The valve port top is provided with notch, and there is screw thread in the valve body outside; The Capsule material adopts Ethylene Propylene Terpolymer alkene rubber or fluosilicic thermoplastics.
Adopt technique scheme, because Capsule energy acid-proof, flexible, reasonable with the valve port fit clearance, calculate suitable weight during design, thereby can effectively realize the automatic shutter of valve, and can prevent the too high accident that causes of inner pressure of battery on the one hand, can keep battery to have on the other hand and press in certain, to keep operate as normal, play automatic control action.When valve was opened discharge gas, the acid mist in the gas at first ran into the acid-blocking piece of valve port below, is condensed into drop and gets back to battery; The small amount of acid spray goes out valve port after filter acid film filters to be unlikely overflows, thereby prevents the battery dehydration, and extending battery life is also avoided environmental pollution.Notch on the valve port then plays explosion-proof when Capsule contingency becomes normally closed situation, improve fail safe.
Further specify the utility model below in conjunction with drawings and Examples.
Accompanying drawing is the utility model structural representation.
The inner chamber of valve body 9 is provided with valve port 3, and Capsule 7 is enclosed within on the valve port, becomes matched in clearance, and and embedded piece 4 between gapped.There is the two-layer semi-circular tongues that is oppositely arranged 8 below, valve port inside.The filter acid film 2 that is positioned at the embedded piece top is porous laminated structure, adopts polytetrafluoroethylene to make through special process, and its micropore can stop acid mist, and allows gas pass through.There are two square notches 5 the valve port top.There are screw thread 10 and sealing ring 6 in the valve body outside, can be effectively and cell cover be tightly connected.Valve gap 1 is buckled on the valve body, plays the protection internal structure, prevents the effect that outside air enters.
Claims (6)
1, a kind of A One-Way Pressure Control Valve For Vrla Battery, comprise valve body, valve gap, sealing ring, valve port, Capsule, embedded piece, it is characterized in that valve port and embedded piece are arranged in the body cavity, Capsule is sleeved on the valve port, both become matched in clearance, and Capsule adopts the acid-proof elastomeric material, and is gapped between its upper surface and the embedded piece, the embedded piece top is provided with filter acid film, and this filter acid film is a porous laminated structure.
2,, it is characterized in that below, valve port inside is provided with acid-blocking piece by the described uniaxial pressure control valve of claim 1.
