The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The specific structure of the explosion-proof valve according to the embodiment of the present invention will be described with reference to fig. 1 to 3.
The utility model discloses an explosion-proof valve, as shown in fig. 1-fig. 3, this explosion-proof valve cooperation is in the pressure release mouth 110 department of box 100, explosion-proof valve includes valve body 1, case 2, regulating part 3 and elastic component 4, valve body 1 wears to establish in pressure release mouth 110, valve body 1 has mating holes 101, case 2 cooperation is in mating holes 101, case 2's one end can cover pressure release mouth 110, the other end stretches into inside box 100, regulating part 3 cooperation stretches into the one end of box 100 at case 2, 4 covers of elastic component are established on case 2, and elastic component 4's one end is only supported on valve body 1, the other end is only supported on regulating part 3.
It can be understood that, in the actual installation process, the valve body 1 is installed in the pressure relief opening 110, then the valve core 2 is fitted in the fitting hole 101, the elastic member 4 is sleeved at one end of the valve core 2 extending into the box body 100, and finally the adjusting member 3 is sleeved on the valve core 2 to compress the elastic member 4 to complete the installation. The working principle of the explosion-proof valve of the embodiment is as follows: after the installation is finished, when the acting force of the air pressure in the box body 100 acting on the valve core 2 can not make the elastic element 4 continue to deform, the valve core 2 can not move, and at the moment, the pressure relief opening 110 is still covered by the valve core 2 and can not be relieved; when the elastic member 4 is further deformed by the force of the air pressure in the box 100 acting on the valve core 2, the valve core 2 is ejected out to make the pressure relief port 110 leak out, thereby achieving the pressure relief function. That is, only when the force of the air pressure in the case 100 acting on the valve element 2 is greater than the elastic force of the elastic member 4, the valve element 2 is ejected to perform the pressure relief function. In the whole process, the larger the pre-deformation generated by the acting force of the adjusting piece 3 on the elastic piece 4 is, the larger the detonation pressure of the corresponding whole explosion-proof valve is, and conversely, the smaller the pre-deformation generated by the acting force of the adjusting piece 3 on the elastic piece 4 is, the smaller the detonation pressure of the corresponding whole explosion-proof valve is. Therefore, in the actual use process, the size of the pre-deformation amount of the elastic part 4 can be adjusted by adjusting the position of the adjusting part 3, so that the detonation pressure of the explosion-proof valve can be adjusted, and the explosion-proof requirements of different working conditions and different specifications can be better met.

When the explosion-proof valve is used on a compressor, the box body can be a shell of the compressor or a connecting pipeline of the compressor, and can be selected according to actual requirements.
The other end of the valve core 2 in the present embodiment extending into the box 100 means that the valve core 2 needs to pass through the box 100, since the box is not necessarily the outer shell of the whole device. For example, when the explosion-proof valve is arranged on the cell top plate, one end of the valve core 2 is inserted into the cell, and the other end is positioned above the cell top plate, but for the whole battery pack, the valve core is positioned inside the shell of the whole battery pack. When the explosion-proof valve is arranged on the housing of the battery pack, the entire valve cartridge 2 is again located outside the housing of the cell, compared to the individual cells. That is, in the actual use process, the position of the valve core 2 can be set according to the actual requirement.
