insulation cut-off valve. The principle of heat insulation valve structure abstract: the thermal insulation of valve and valve body, a layer of metal shell welding by steam, thermal oil, cooling water, air conditioning, etc into the metal case, make the body of the medium at room temperature, heating, cooling and other conditions at the specified temperature, have the effect of heat preservation or cold storage. Thermal insulation Industrial Valves will be high viscosity curing at room temperature, heat preservation, cold media such as steam, guarantee the normal work of the valve of medium. Mechanism of heat insulation valve: the heat preservation Industrial Valves has good heat preservation and cooling characteristics, and the diameter of the pipe diameter, and can effectively reduce the heat loss of pipe medium. It has good heat preservation and cooling characteristic, and can effectively reduce heat loss in the medium in pipeline. Insulation valve is widely used in petroleum, chemical, metallurgical, pharmaceutical and other system, effectively reduce the heat loss in the pipe, prevent the crystallization of the medium, solidification and other similar phenomena. Insulation valve is used to make the material in the heat preservation valve when the temperature is high or low to medium heat preservation effect, make the medium not condensation or attached on the body, make the normal operation of the opening and closing of the valve.
