Explosion-proof pressure detection device for sealing ring

Abstract

The invention discloses a sealing ring anti-explosion pressure detection device, and belongs to the field of sealing ring anti-explosion pressure detection.The device comprises a detection mold body, a branch cavity is formed in the detection mold body, a plurality of high-pressure pipelines are installed in the detection mold body, and the bottoms of the high-pressure pipelines communicate with the interiors of the branch cavities; a first high-pressure three-way pipe is installed on the right side of the detection mold body, the left end of the first high-pressure three-way pipe is communicated with the interior of the branch cavity, a three-way air release valve is installed on the top of the first high-pressure three-way pipe, a pressure display meter is installed on the top of the three-way air release valve, and a second high-pressure three-way pipe is installed on the high-pressure pipeline; and a plurality of sealing ring explosion-proof test holes are formed in the top of the detection mold main body. According to the invention, the test data of the battery sealing ring is accurate, no missing test exists, and the explosion-proof performance and the stability of the battery are well guaranteed.

Description

technical field [0001] The invention relates to the field of explosion-proof pressure detection of sealing rings, and more specifically relates to an explosion-proof pressure detection device of sealing rings. Background technique [0002] Now the structure of the sealing ring explosion-proof pressure detection device is: through the high-pressure compressed air through the pipeline, the regulating valve, the air pressure switch, the pressure gauge and the sealing ring placing mold to carry out the sealing ring detection device. [0003] Disadvantages of the existing sealing ring explosion-proof pressure detection device: The first disadvantage is that the copper needle is easy to touch the bottom plane when the sealing ring is detected, causing the offset to be out of position, which is easy to cause damage to the sealing ring. The second disadvantage is that when testing the sealing ring, the explosion-proof pressure of the sealing ring is easily leaked, resulting in inacc...

[0003] Disadvantages of the existing sealing ring explosion-proof pressure detection device: the first disadvantage is that the copper needle is easy to touch the bottom plane when the sealing ring is detected, causing the offset to be out of position, which is easy to cause damage to the sealing ring

The second disadvantage is that when testing the sealing ring, the explosion-proof pressure of the sealing ring is easily leaked around the seal, resulting in inaccurate explosion-proof pressure test data. The third disadvantage is that it is difficult to take out the sealing ring after the sealing ring compression detection process is completed.

[0004] The reason for the first shortcoming is that the foothold of the copper needle is easy to shift to withstand the damage caused by the copper needle. The second shortcoming is that the size of the outer O-ring where the sealing ring is placed is not suitable. The third shortcoming is that the bottom of the sealing ring is placed If the size of the mold is too small, it is easy to jam the sealing ring, making it difficult to take out
