Description

New energy battery explosion-proof valve with pressure beads

Technical Field

The utility model relates to a battery explosion-proof valve technical field, concretely relates to new forms of energy battery explosion-proof valve of area pressure pearl.

Background

At present, new energy batteries are sealed, high temperature can be generated during working, and an anti-explosion vent valve is needed to release hot air at the moment. In the disclosed technology, as disclosed in publication No.: "CN 109686896A", discloses an explosion-proof valve, including valve body, ventilated membrane and screening glass, the valve body has a holding chamber, and the holding intracavity is provided with explosion-proof pointed cone, and explosion-proof pointed cone includes two at least arris pieces, and each arris piece is connected and is formed an explosion-proof pointed cone that the top has the tip cone, is many arriss type, sets up the exhaust hole on the valve body, is provided with ventilated membrane and screening glass on the valve body, and the ventilated membrane sets up between screening glass and explosion-proof pointed cone. The battery realizes the gas exchange with the outside through installing the explosion-proof valve on the battery case, when battery pressure is too big, when reaching the critical value, explosion-proof membrane paper presses to the direction in holding chamber, and puncture by the explosion-proof point awl that the holding intracavity set up, the orientation of edges piece is followed with the ventilated membrane to many arris limit structure on the explosion-proof point awl is torn in the multiaspect, make the air current realize the reposition of redundant personnel along the edge groove that forms between edges piece and the edges piece, make the air current after the reposition of redundant personnel pass through in the exhaust hole rapidly outside the explosion-proof valve of discharging, make the battery case pass through explosion-proof valve and outside intercommunication, realize explosion-proof function. In the above, once the critical value is reached, the bursting disk paper is punctured, and then the bursting disk paper needs to be replaced by new bursting disk paper.

Detailed Description

The present invention will be described in detail with reference to the following embodiments and accompanying drawings.

Referring to fig. 1 to 4, the new energy battery explosion-proof valve with the pressure bead comprises

The valve body 1 is internally provided with an accommodating cavity 105, the circumference of the accommodating cavity is a valve wall 100, a plurality of stoppers 103 which are uniformly arranged are arranged on the same horizontal plane along the inner side of the valve wall,

a mounting groove 104 of the valve core seat is arranged in the middle of the accommodating cavity in the middle of the valve body,

the valve core seat 2 is arranged in the mounting groove,

a breathable film 4 is arranged at the lower part of the valve core seat 2, a breathable film through hole 3 is arranged at the middle part of the waterproof breathable film, a sealing ring 5 is arranged in the breathable film through hole 3, a ball valve 6 is pressed and sealed on the sealing ring, the upper part of the ball valve 6 is propped by a spring 8, the lower part of the spring 8 is arranged on a spring seat 71 arranged at the middle part of the valve cover,

the valve cover is provided with a fixing buckle 70 matched with the stop block, and the valve cover is fixed on the accommodating cavity.

Further, the breathable film is a waterproof breathable film.

When the explosion-proof valve is installed, the valve core seat is installed in the installation groove firstly, the installation groove is a cylindrical shape protruding out of the valve body, threads are arranged on the outer side of the protruding portion and used for installing the explosion-proof valve, after the valve core seat is installed, the breathable film is placed on the lower portion of the valve core seat, the breathable film through hole formed in the middle of the breathable film is propped against the ball valve, the lower portion of the ball valve is supported by a spring, and after the valve cover is installed on the valve cover, the valve cover is rotated to enable the fixing buckle to be matched and fixed with the stop block.
