BZ41H insulated gate valve

Overview of BZ41H insulated gate valve: The insulated gate valve is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other systems. The jacket of the valve is welded between the two flanges of the valve. The side and bottom of the valve are equipped with the connection port of the jacket. The jacket can freely flow through steam or other thermal insulation medium to ensure that the viscous medium can flow through the valve smoothly.

BZ41H insulated gate valve

Brief introduction of insulation valve structure:
The heat preservation valve is welded with a layer of metal jacket in the valve body. By injecting steam, heat transfer oil, cooling water and air conditioner into the metal jacket, the medium of the valve body can reach the required temperature under normal temperature, heating and cooling conditions, so as to play the role of heat preservation or cold preservation. Insulation valve is used in the room temperature will solidify high viscosity, steam or other insulation, insulation medium, to ensure that the valve medium can work normally.


The principle of heat preservation valve:
The valve has good heat preservation and cold preservation characteristics, and the valve diameter is consistent with the pipe diameter, and can effectively reduce the heat loss of medium in the pipeline. It has good heat preservation and cold keeping property, and can effectively reduce the heat loss of medium in the pipeline. The heat preservation valve has been widely used in petroleum, chemical, metallurgy, pharmaceutical and other systems, which can effectively reduce the loss of medium heat in the pipeline and prevent the appearance of the similar phenomena such as medium crystallization and solidification. The function of the heat preservation valve is to pass through the valve under the condition of high or low temperature, the material in the insulation valve will have the insulation effect on the medium, so that the medium will not condense or stick to the valve body, so that the valve can be opened and closed to operate normally.


Classification of insulation valves:
The products conform to GB, DIN, ANSI and other international standards. Insulation valve is also divided into: insulation ball valve, insulation gate valve, insulation butterfly valve, insulation discharge valve, insulation stop valve, Insulation check valve, insulation filter. Insulation valve, etc. The products are widely used, suitable for large and small caliber, complete variety.
