Product Introduction of Electric Thermal Insulation Ball Valve
The Electric Insulation Ball Valve is composed of an electric quarter-turn actuator and a jacketed insulation ball valve. It has good thermal insulation and cold insulation characteristics, and the pneumatic insulation ball valve has The diameter is consistent with the pipe diameter, and at the same time it can effectively reduce the heat loss of the medium in the pipeline. It adopts an integrated structure and has a built-in servo system in the electric actuator. There is no need for a separate servo amplifier. The operation can be controlled by inputting a control signal or power supply. Electric thermal insulation ball valves are mainly used in various systems such as petroleum, chemical industry, metallurgy, pharmaceuticals, food, etc. to transport high-viscosity media that will solidify at room temperature. Since the electric insulated ball valve adopts an integral structure, the jacketed insulated electric ball valve is smaller and lighter than ordinary ball valves, has no leakage, and has good sealing performance. The jacket is welded with carbon steel pipes and is more pressure-resistant than cast.
Working principle of electric thermal insulation ball valve
Electric thermal insulation ball valve adopts steam jacket insulation. Therefore, even if the outside temperature drops below zero, the ball valve can still operate flexibly to ensure that the oil pipeline can be disconnected. Its advantage is that ordinary control valves do not have it. Thermal insulation ball valve is an ideal control valve for heavy oil transportation pipelines. Steam, thermal oil, cooling water, air conditioning, etc. are injected into the jacket according to user needs. Use the entire valve to warm or cool to the desired temperature. Can prevent medium crystallization. The electric thermal insulation ball valve has the characteristics of heat preservation and cold preservation. Flange connections manufactured according to design and standards are used in petroleum, chemical, metallurgy, and pharmaceutical industries.
Product features of electric thermal insulation ball valve
This product has good thermal insulation and cold insulation characteristics, and the diameter of the valve is consistent with the diameter of the pipe. At the same time, it can effectively reduce the heat loss of the medium in the pipeline.
Mainly for solidified high-viscosity media and easy-to-crystallize media.
Due to the integral structure, the insulated ball valve is smaller and lighter than ordinary ball valves, has no leakage, and has good sealing performance. The jacket is welded with carbon steel pipes and is more pressure-resistant than cast.
