Description

Technical Field

[0001] The utility model relates to the field of thermal insulation sleeves, in particular to a thermal insulation sleeve for a metal ball valve. Background Art

[0002] The ball valve is a valve that uses a sphere with a circular channel as an opening and closing part. The ball rotates with the valve stem to achieve the opening and closing action. The opening and closing part of the ball valve is a sphere with a hole, which rotates around an axis perpendicular to the channel to achieve the purpose of opening and closing the channel. The ball valve is mainly used to open and close pipelines and equipment media. The ball valve insulation cover is tailored according to the actual size of the ball valve. It consists of a three-layer structure of insulation layer, insulation layer and protective layer. It is a flexible insulation. The ball valve insulation cover tightly wraps the valve, has a neat appearance, can be wiped, and has good insulation and heat insulation effects. The temperature application range is -70~1400℃, the thickness is 30~100mm, and the surface temperature after insulation drops to 35~45℃, and the energy saving efficiency is increased by more than 40%. It has significant advantages such as measurement customization, detachable, reusable, fireproof, hydrophobic, antibacterial, and chemical resistance. A Chinese patent discloses a metal ball valve insulation cover (authorization announcement number CN 204985812U), this patented technology can be wrapped on the outer surface of a metal ball valve, including a first insulation layer and a second insulation layer, the first insulation layer is located inside the second insulation layer, and the ball valve is wrapped with two layers of insulation materials. Further, a convex hook is provided on one side of each block insulation material, and a concave hook groove is provided on the opposite side thereof. The two adjacent blocks of insulation materials are connected by the convex hook and the concave hook groove, and are translated so that the convex hook hooks the concave hook groove, and the splicing is stable. Further, the inner surface of the second block insulation material of the second insulation layer has a conical protrusion, and the conical protrusion is cross-shaped and located on the inner surface of the second block insulation material. The conical protrusion is inserted into the splicing gap of the two blocks of insulation materials on the outer surface of the first insulation layer. The conical protrusion is inserted into the gap to enhance the stability of the hook of the first block insulation material of the first insulation layer. However, the insulation of pipes and valves of different shapes cannot be changed and used, and the spatial adaptation range is small. Therefore, those skilled in the art provide a metal ball valve insulation sleeve to solve the problems raised in the above background technology. Utility Model Content
