Description

Technical Field

[0001] This utility model relates to the field of high-temperature shut-off valves, specifically a high-temperature shut-off valve with heat sink. Background Technology

[0002] A Chinese patent document with publication number CN219119952U discloses a DC shut-off valve with heat sink, including a valve body and a valve seat. The valve body is connected to an external device, and the valve seat is detachably connected to the valve body. The valve body is provided with a heat dissipation mechanism and an installation mechanism. The heat dissipation mechanism includes a heat spreader plate, heat sinks, fixing bolts, a heat-conducting surface, and heat-conducting blocks. The heat-conducting surface is installed on the side of the valve body, and multiple heat-conducting blocks are provided, each mounted on the heat-conducting surface. The heat spreader plate has heat-conducting holes, and the heat-conducting blocks are mounted on the heat-conducting holes. The heat dissipation mechanism is designed so that heat can be quickly transferred to the heat spreader plate by the action of multiple heat-conducting blocks, and then the heat can be discharged by the action of multiple heat sinks, thereby avoiding heat accumulation in the valve body.

[0003] During use, the valve cover of the gate valve must first be sealed and connected with the valve cover of the docking valve. In traditional technical solutions, flange connection is usually used to seal and connect the valve cover of the gate valve with the valve cover of the docking valve. However, since the flange has many bolt holes and no positioning components, when sealing and connecting, the workers need to align the through holes on the flange accordingly before bolting it, which increases the labor intensity of the workers. In addition, since a lot of bolts are used, they are easy to lose during disassembly or installation.

[0004] Therefore, this utility model proposes a fireproof glass partition stable support structure to solve the above problems. Utility Model Content
