Abstract
A double-filter-element column type safety valve for valve-controlled sealed lead-acid accumulator is composed of valve body, rubber column, screw plug, acid filter and sealing washer. The filter acid sheet is a double filter sheet, the aperture is 25-40 μm, the valve body is provided with screw threads, and the joint of the cap head is in arc transition. The utility model discloses when exhausting, through two-layer filtration, it is effectual to strain sour, reduces the interior moisture loss of battery, avoids environmental pollution, extension battery life. And threaded connection and the excessive structure of circular arc improve the locking force, avoid the phenomenon of rupture, improve fail safe nature.
Description
The utility model relates to a kind of safety valve, or outlet valve, especially for the pillar safety valve of the band acid filtering plate of valve-control sealed lead acid battery.
It is the control inner pressure of battery that the used safety valve of valve-control sealed lead acid battery mainly acts on, and the acid mist that reduces in the battery overflows, and realizes the sealing of battery.Its working principle is the hydrogen that produces of the oxygen that produces when a galvanic anode and negative electrode compound tense fully, inner pressure of battery will raise, the interior pressure when being elevated to specified value, safety valve is opened automatically, gas is discharged, and acid mist will be filtered simultaneously, press in after the exhaust when reaching lower limit, safety valve just cuts out automatically, has so both guaranteed the safe in utilization and working life of battery, avoids environmental pollution again.
Safety valve in the past generally has only a slice acid filtering plate, and it is bad to filter sour effect; Safety valve mostly is clamping-type with combining of battery case, and card is loose not to have seal action, has tightened the pressure that causes the valve body distortion easily and change open and close valve, and phenomenon of rupture also can appear in the corner of valve body upper valve base cap subfacies sometimes, causes serious consequence.
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of filter acid effective, the two filter disc pillar safety valves of safe and reliable valve-control sealed lead acid battery.
The technical solution of the utility model is: valve-control sealed lead acid battery comprises valve body, rubber column, plug screw, acid filtering plate and seal washer with two filter disc pillar safety valves, and valve body is made of valve seat and valve seat cap head two-part.Described acid filtering plate is two filter discs, and the valve seat outer surface has screw thread, and valve seat and valve seat cap head joint are that circular arc is excessive.
The aperture of micropore is 25～40 μ m on the above-mentioned acid filtering plate, and the described circular arc excessively radius of arc at place is 2～4mm.
Adopt technique scheme, too high when inner pressure of battery, safety valve is opened, when discharging gas, by gas take out of contain sour water part and run into the first layer filter disc after, major part is returned inside battery, the small amount of moisture of leakage is blocked again by the second layer filter disc time.Through twice filtration, have only 1/4th of former one deck filter disc with the excessive moisture content of gas, strengthen the sour effect of filter greatly, reduce the inside battery moisture loss, both avoided environmental pollution, prolonged battery working life again.In addition, adopt screw thread and circular arc excessive on the valve body, can make safety valve locking power improve 3 times, and can not rupture, guarantee that it is safe and reliable.
Further specify the utility model below in conjunction with drawings and Examples.
Accompanying drawing is the utility model structural representation.
As figure, the valve body of this safety valve is made of valve seat 1 and valve seat cap head 6, and the 8 one-tenth circular arcs in both joints are excessive, and R gets 3mm, and seal washer 7 matches with it.Body cavity has rubber column 2, and there is plug screw 3 top, and acid filtering plate 4 and acid filtering plate 5 are separately positioned on the inside and the top of plug screw, and the aperture of acid filtering plate micropore is 35 μ m.The outer surface of valve seat has screw thread 9.
Claims (3)
1, the two filter disc pillar safety valves of a kind of valve-control sealed lead acid battery, comprise valve body, rubber column, plug screw, acid filtering plate and seal washer, valve body is made of valve seat and valve seat cap head two-part, it is characterized in that acid filtering plate is two filter discs, the valve seat outer surface has screw thread, and valve seat and valve seat cap head joint are that circular arc is excessive.
2, by described pair of filter disc pillar of claim 1 safety valve, the aperture that it is characterized in that micropore on the acid filtering plate is 25～40 μ m.
