[0022] As attached Figure 3 As shown, in the above embodiment, specifically, the movable heat-conducting rod frame structure 5 includes a hollow valve stem 51, a hollow half valve ball 52 is welded at the lower end of the hollow valve stem 51; a connecting head 53 is welded at the lower end of the hollow half valve ball 52; turning the wrench drives the hollow valve stem 51, the hollow half valve ball 52 and the connecting head 53 to rotate to control the flow of the valve body 1 in the pipeline.

[0023] As attached Figure 4 As shown, in the above embodiment, specifically, the heat dissipation and air guide box structure 4 includes a mounting box 41, and working fans 42 are bolted on the left and right sides of the mounting box 41, and an assembly rod 43 is bolted between the working fans 42; a lower filter 44 is movably inlaid on the upper part of the inner wall of the mounting box 41; an upper protective net 45 is bolted on the upper end of the mounting box 41; the working fan 42 works in conjunction with the hollow valve stem 51 and the hollow half valve ball 52 to absorb heat and discharge it from the lower filter 44 and the upper protective net 45 for heat dissipation.

[0024] In the above embodiment, specifically, a sealing gasket is provided on the upper portion of the contact sealing disk 92 , and the contact sealing disk 92 cooperates with the sealing gasket to closely adhere to the interior of the lower valve seat 6 , so as to seal the connection between the regulating column 91 and the disassembly cover 8 .

[0025] In the above embodiment, specifically, the hollow valve stem 51 is movably embedded in the interior of the valve body 1, the lower end of the connecting head 53 is movably embedded above the interior of the lower valve seat 6, and corresponds to the high temperature resistant sealing gasket 96, and the hollow valve stem 51 is movably embedded in the upper side of the interior of the valve body 1 and the interior of the upper valve seat 2, so as to facilitate connection with other structures for use.

[0029] How it works

[0030] The working principle of the present invention is as follows: when installed on a pipeline to control flow and relieve pressure safely, the two ends of the valve body 1 are installed on the pipeline through flanges, and then a wrench is installed on the upper bolts of the outer wall of the hollow valve stem 51, so that the wrench can be turned to drive the hollow valve stem 51, the hollow half valve ball 52 and the connecting head 53 to rotate to control the flow of the valve body 1 on the pipeline. During use, the working fan 42 works in conjunction with the hollow valve stem 51 and the hollow half valve ball 52 to absorb heat and discharge it from the lower filter screen 44 and the upper protective screen 45 for heat dissipation. When the hollow half valve ball 52 seals When the internal pressure of the valve body 1 is too large, it will impact the high-temperature resistant sealing gasket 96 and the movable disk 95, and then drive the movable guide rod 93 to move in the adjusting column 91. The movable movable disk 95 will descend in the lower valve seat 6 and connect the left end of the discharge pipe 7 with the valve body 1 for pressure relief. When it is necessary to adjust the elastic force of the pressure spring 94 and thus adjust the pressure of the pressure relief during use, the adjusting column 91 inside the disassembly cover 8 is turned by a hexagonal wrench to move in the lower valve seat 6, thereby adjusting the position of the contact sealing disk 92 and adjusting the length and elastic force of the pressure spring 94 for use.
