Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation sleeves, in particular to a soft pipeline valve thermal insulation sleeve. Background Art

[0002] Heat insulation cover is a kind of heat insulation material used to protect objects from heat loss. It is usually made of materials such as high-density polyethylene (HDPE) or polyvinyl chloride (PVC), and has excellent heat insulation and chemical corrosion resistance. Heat insulation cover is widely used in construction, refrigeration, freezing, air conditioning and other industries to maintain the surface temperature of objects and reduce heat energy loss. The main function of the heat insulation cover is heat insulation. It can isolate objects from the outside world and prevent heat loss. The outer layer of the heat insulation cover is usually made of waterproof, moisture-proof and corrosion-resistant materials to ensure its service life. In the prior art, soft pipe valves usually use various heat insulation covers to insulate the valves.

[0003] Traditional installation methods of soft pipe valve insulation covers are mostly fixed with tape or bolts, which are troublesome to install and disassemble. In addition, because the soft pipe needs to be moved, the contact surface between the insulation cover and the soft pipe will produce friction or squeeze each other, which can easily cause wear of the soft pipe. In winter, the valve may freeze even if it is protected by an insulation cover. The existing soft pipe valve protection cover does not have a thawing function. Therefore, a soft pipe valve insulation cover is proposed to address the above problems. Utility Model Content

At this time, the first rotating shaft rotates, and the first insulation shell and the second insulation shell are closely fitted. Then the slider is pulled, and the return spring is stretched by external force, and the slider slides in the slide groove. At the same time, the connecting rod is turned over, and the second rotating shaft rotates until the engaging block is closely fitted with the first insulation shell, and the slider is released. The slider is connected with the engaging block, and the insulation cover is installed.

[0013] 2. In the utility model, the limit cylinder, limit spring, limit block, buffer plate and rubber particles are provided to protect the hose connected to the valve and reduce the wear thereof.
