The second limit safety column 5 and the first limit safety column 4 are staggered up and down to ensure the overall structural strength. The second limit safety column 5 and the first limit safety column 4 are respectively provided with heat dissipation auxiliary safety grooves on both side end faces, which have better heat dissipation auxiliary effect and higher heat dissipation coordination efficiency during use. It has a simple overall structure, and as a separate valve body, it is also a separate component, which is more convenient during production and processing. During assembly and coordination, it is fastened and coordinated through the threaded grooves arranged on the outside. By setting the limit safety column inside, on the one hand, it can effectively improve the overall structural strength, and on the other hand, it plays a role of limit coordination for the sealing components at the upper and lower ends. At the same time, it can also dissipate heat and guide the flow of the liquid inside the valve body when it is coordinated, so that the valve core inside the valve body is safer and more durable when it is used in an active coordination manner, and can meet the safety requirements of the high-precision air release valve when in use. It has stronger heat resistance during the overall use process, and lower use cost and production.

[0020] Preferably, the second limit safety column 5 and the first limit safety column 4 are connected to the valve body main structure 1 by integral molding, so that the internal structure has higher precision, better structural strength, and stronger overall durability during use.
