Description

Technical Field

[0001] The utility model relates to the technical field of valve insulation, and more specifically to a stainless steel valve insulation cover. Background Art

[0002] Stainless steel valves refer to valves made of stainless steel materials. They can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. When controlling and transporting in some low-temperature environments, in order to avoid the valve from freezing, it is necessary to insulate its exterior. After searching, the patent with the authorization publication number of CN213900085U discloses an aluminum alloy valve insulation sleeve. The lower end of the shell is arranged on the heat-conducting component, and the upper end is provided with a shell composed of at least two structural splits. The structural split includes a long first half pipe and a second half pipe arranged vertically below the half pipe. The first half pipe and the second half pipe are respectively provided with a first groove and a second groove. Multiple first grooves form a neck cover, and multiple second grooves form a valve flange. At least two types of insulation cotton are provided on the opposite end faces of the structural split. This structure is provided with a heat dissipation groove at the valve flange connection. The entire structure is manufactured before leaving the factory and is directly installed and used on site. Its characteristics are: easy installation, maintenance and disassembly; reusable, reducing the overall maintenance cost of the device; long-term high efficiency and energy saving; preventing the valve connection screw from deforming and causing leakage on the flange sealing surface, eliminating safety hazards; reducing noise, effectively absorbing toxic gases, and reducing the harm of chemical equipment to the human body.

[0003] However, the above patent solution still has the following shortcomings: it can only insulate the valve body of the stainless steel valve, which is not convenient for protecting the hand wheel, and the insulation effect is poor; and it is cumbersome to connect and disassemble using multiple fasteners. For this reason, we propose a stainless steel valve insulation cover. Utility Model Content
