[0002] A safety valve refers to a valve installed on a pressure vessel to play a protective role. When the medium pressure in the system exceeds the specified value, the safety valve will automatically open and discharge part of the medium to prevent the pressure from continuing to rise. When the pressure drops to the specified value, the safety valve will automatically close. The safety valve belongs to the category of automatic valves and is mainly used on boilers, pressure vessels and pipelines to control the pressure not to exceed the specified value, which plays an important protective role for personal safety and equipment operation. In order to improve the use efficiency of the safety valve, a connection structure is needed. However, the existing connection structure still has the following deficiencies:

[0003] When the existing connection structure is in use, since most connection structures do not have a limiting structure during the docking process of the safety valve, it is necessary to manually lift, dock and install the safety valve during the connection process, which makes the connection process of the safety valve time-consuming and laborious, and further affects the rapid installation of the safety valve, resulting in the problems of decreased practicability and reduced use efficiency of the connection structure.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a connection structure of a safety valve is proposed. Content of the Utility Model

An external mounting thread is opened on the outer part of the second connection flange, and a threaded mounting ring is connected to the outer part of the second connection flange.

[0007] Further, the number of the docking blocks is set to four, and the four docking blocks are equidistantly distributed inside the first connection flange.

[0008] Further, the external dimension of the docking block is adapted to the internal dimension of the docking groove, and the docking block is embeddedly connected to the second connection flange through the docking groove.

[0009] Further, the internal dimensions of the threaded mounting groove are adapted to the external dimensions of the mounting bolt, and the mounting bolt is rotatably connected to the first connecting flange through the threaded mounting groove.
