[0002] Stainless steel valve fire cover: a safety device used to protect valves in the event of a fire. It is usually made of stainless steel and has the characteristics of high temperature resistance and corrosion resistance. The main function of the fire cover is to prevent flames and high temperatures from causing damage or danger to the valve and its surrounding environment when a fire occurs. The fire cover is usually designed as a sealed structure that can effectively isolate the heat and flames of the fire and prevent the fire from spreading to valve components or piping systems. This device is widely used in industrial fields, commercial buildings and other places that require fire safety measures.

[0003] The stainless steel valve fire covers in the prior art are mostly used to protect the valves of metal pipes. The surface of the metal pipes is relatively smooth, and it is not easy to fix the stainless steel valve fire covers when installing them, resulting in poor fireproof performance and affecting the effect of isolating the heat and flames of the fire.

[0004] To this end, we provide a stainless steel valve fire cover to solve the above problems. Utility Model Content

When the surface of the semicircular ball contacts the groove on the surface of the buckle 4, the reset spring 7 is released. The spring 7 rebounds to make the semicircular ball clamp the buckle 4. At this time, the inner cavity of the semicircular fireproof cover 2 wraps the valve surface to install the fireproof cover. When the semicircular tube 1 is fixed, the surface of the pipeline to be installed contacts with the arc plate 14 and squeezes the arc plate 14, so that the telescopic spring 13 drives the arc plate 14 to move, so as to clamp the pipeline to be installed. When a fire occurs, the sealing layer 9, the insulation layer 10 and the anti-corrosion layer 11 inside the fireproof cover are used to isolate the heat and flame generated by the fire to protect the valve.
