Insulating sleeve valves are mainly used for heat preservation occasions. When the crystallization temperature of the process medium increases, or the viscosity increases or the fluid solidifies due to the decrease of the fluid temperature, it is necessary to install a steam insulation sleeve device on the valve body and the upper valve cover of the regulating valve. According to technological requirements, the production process can be carried out automatically. Regarding the form adopted by the valve body, the anti-blocking performance of the valve body is mainly considered according to the working conditions.

Because the purpose of the insulating jacket is to prevent blocking, and the straight-stroke valve has poor blocking performance, it is recommended to choose eccentric rotary valves, ball valves, butterfly valves, etc. with good blocking performance when selecting valve types. Especially the large diameter butterfly valve. When heat preservation and cold preservation are required, the types of heat preservation jackets that are more suitable for exhaust solenoid valves include ball valves, butterfly valves, plug valves, check valves, discharge valves, gate valves, etc. Dedicated cold ball valve.

The insulation jacket valve model product has excellent insulation and cold insulation performance, the valve diameter is the same as the pipe diameter, and the medium flow resistance of the shift solenoid valve is small. It is most suitable for the easy solidification and high viscosity medium. And can effectively reduce the heat loss of the medium in the tube.

Due to the integrated structure, the heat-insulated ball valve is smaller and lighter than the ordinary ball valve, and has no external leakage, and has good sealing. The jacket is welded by carbon steel and is more pressure-resistant than the casting.
