Description

Technical Field

[0001] The utility model provides a high temperature resistant gate valve, belonging to the technical field of gate valves. Background Art

[0002] The gate valve is a valve that uses a gate as an opening and closing part and moves vertically along the axis of the valve seat to achieve opening and closing. High-temperature gate valve is a type of gate valve that can work normally in a high-temperature environment. It is used in high-temperature occasions such as nuclear power, power plants and special media. It has high-temperature resistant materials (such as high-temperature alloys, ceramics, etc., which can maintain stable performance in a high-temperature environment), heat-resistant design (with special heat-resistant design, including valve body, seals and other components to ensure reliable operation in a high-temperature environment), high-temperature sealing performance (can effectively prevent medium leakage and outside air from entering the valve), fast response and remote control, etc., and is widely used in fluid control and regulation in high-temperature process flows.

[0003] The existing high-temperature resistant gate valves can basically meet normal use needs, but lack corresponding protective components. Due to long-term exposure to high temperature, the temperature on the surface of the high-temperature resistant gate valve will inevitably exceed the temperature limit that the human body can adapt to. Once a work error occurs, it is inevitable that the surface of the high-temperature resistant gate valve will be accidentally touched, causing burns to the workers' skin.

[0004] Based on this, the utility model provides a high temperature resistant gate valve, which has a protective component and can conveniently realize the maintenance and operation of the high temperature resistant gate valve body inside the protective component. Utility Model Content

[0010] Furthermore, a handle is provided on the top of the L-shaped protective plate.

[0013] 1. The L-shaped protective plates on both sides are spliced ​​together into a C-shaped structure through the locking assembly, which is surrounded by the outside of the high-temperature resistant gate valve body to prevent the high-temperature resistant gate valve body from being exposed to the outside.
