Abstract
The utility model discloses a safety valve sealing structure of a lead-acid storage battery. The safety valve sealing structure comprises a valve body and a middle cover, wherein the valve body is in a cylinder shape; the lower end of the valve body is provided with internal thread; a ring-shaped bulge is arranged at the port of the valve body in the internal thread; the middle cover is provided with an air outlet mouth; the air outlet mouth is provided with external thread matched with the internal thread; and the top of an inner hole of the air outlet mouth is in interference fit with the ring-shaped bulge, so that the safety valve sealing structure has the sealing function. After the technical scheme is adopted, the sealing structure does not need a sealing gasket, so that the problems that the sealing gasket is easily aged and the like can be avoided, and the performances and the service life of the battery are effectively guaranteed; and the scheme is simple in structure and saves the cost.
Description
Technical field
The utility model relates to a kind of storage battery, is specifically related to the lead-acid accumulator protection valve hermetically-sealed construction.
Background technology
Accumulator protection valve is the vitals of valve-regulated lead-acid battery, directly acts on internal storage battery sealed reaction efficient, when the inside battery gas pressure surpasses certain value, safety valve is opened automatically, discharge gas, close automatically then, safety valve is airtight under the conventional state.Safety valve adopts screw-type and these two kinds of structures of bayonet type at present, and safety valve and middle cover mating surface are provided with rubber gasket.Rubber seal is lined with certain drawback, and the time has been grown easily aging, sclerosis, causes the sealing of safety valve poor, easily causes safety valve easing gas leakage, causes the serious dehydration of cell negative terminal, has a strong impact on serviceability and the life-span of storage battery.
Summary of the invention
The purpose of this utility model is: a kind of lead-acid accumulator protection valve hermetically-sealed construction is provided, can solves the problem that the conventional security valve insert easily wears out.
The utility model is achieved through the following technical solutions:
The lead-acid accumulator protection valve hermetically-sealed construction comprises valve body and middle cover, and described valve body is cylindrical, and the lower end of valve body is provided with internal thread, and the valve body port of internal thread inside is provided with an annular protrusion; Be covered with outlet nozzle in described, described outlet nozzle is provided with the external screw thread that is complementary with internal thread, the internal orifice top of outlet nozzle and annular protrusion interference fit.
As further preferred version of the present utility model, the outer ring surface of described annular protrusion and horizontal plane have an angle β.
As further preferred version of the present utility model, the angle of angle β is 45 °～85 °.
As further preferred version of the present utility model, the internal orifice top of described outlet nozzle is provided with fillet.
As further preferred version of the present utility model, the radius of described fillet is 0.5mm～1mm.
The utlity model has following beneficial effect:
Safety valve sealing structure of the present utility model, the bottom of safety valve are provided with the oblique top wall of internal thread and projection, in be covered with the external screw thread that is complementary with internal thread, and the junction of external screw thread wall and oblique top wall is provided with fillet.By the interference fit of this fillet and oblique top wall, reach the effect of sealing, no longer need sealing ring, also just avoided the easy aging problem of sealing ring, effectively guaranteed performance and the useful life of battery.This scenario-frame is simple simultaneously, saves cost.
Description of drawings
Fig. 1 is the utility model structural representation.
