Brief Introduction of Insulation Valve

by:Sure     2021-08-16
Insulation valve is the general name of the valve with a metal jacket added to the outside of the valve body, also called jacketed valve. The types of insulation valves include: insulation gate valve, insulation stop valve, insulation butterfly valve, insulation plug valve, insulation filter, insulation discharge valve, etc. Insulation valve is a general term for valves with a metal jacket added to the outside of the valve body by injecting steam, heat-conducting oil, cooling water, air-conditioning, etc. into the metal jacket, so that the medium of the valve body is at room temperature, heating up, and reducing. , Also known as jacketed valve. The types of insulation valves are: insulation gate valve, insulation stop valve, insulation butterfly valve, insulation plug valve, insulation filter, insulation discharge valve, etc. The heat preservation valve is to inject steam, heat transfer oil, cooling water, air-conditioning, etc. into the metal jacket, so that the medium of the valve body reaches the required temperature under the conditions of normal temperature, heating, and cooling, and plays a role of heat preservation or cold preservation. Insulation valves are widely used in various systems such as petroleum, chemical industry, metallurgy, pharmaceuticals, etc., effectively reducing the heat loss of the medium in the pipeline, and preventing the appearance of crystallization and solidification of the medium. The thermal insulation butterfly valve is also called the jacketed butterfly valve. It is a metal jacket welded on the outside of the valve body on the basis of the ordinary three-eccentric metal hard seal butterfly valve. The thermal insulation butterfly valve is equipped with a jacket interface on both sides of the valve body, which can contain steam or Other overheated gases to prevent the medium from solidifying or crystallizing at room temperature. The flange of the thermal insulation butterfly valve is one to two specifications larger than that of the ordinary metal hard seal butterfly valve. It is mainly used in various systems such as petroleum, chemical industry, metallurgy, and pharmaceuticals. For other features, please refer to the detailed parameters of the metal hard seal butterfly valve. Insulation gate valve, also known as jacketed gate valve, is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other systems to transport high-viscosity media that solidify at room temperature. The jacket of this series of valves is welded and installed between the two flanges of the valve, and the side and bottom of the valve are provided with a connection port for the jacket. Due to the addition of the jacket, the size of the connecting flange of this valve is one to two sizes larger than the connecting flange of the ordinary ball valve of the same specification, but the structural length is the same as that of the valve of the same specification, and the jacket can freely flow through steam. Or other hot insulation medium. Insulation stop valve, also known as jacketed stop valve, is mainly used in system pipelines in the chemical, petroleum, pharmaceutical, metallurgical and other industries. Its main function is to transport the medium that will solidify and crystallize at room temperature. . A metal jacket is welded between the two flanges of the BJ41W thermal insulation stop valve. Jacket interfaces are set on the side and bottom of the stop valve to inject steam or other thermal and cold media to ensure that the media in the valve can work normally. The connecting flange of the insulation globe valve is one to two specifications larger than that of the ordinary globe valve. Reduced diameter heat preservation ball valve has the characteristics of heat preservation and cold preservation, and is mainly used in petroleum, chemical, metallurgy, manufacturing and other industries. The BQ41F reduced diameter heat preservation ball valve adopts steam jacket heat preservation, so even if the outside temperature drops below zero, it can still be operated flexibly, especially suitable for heavy oil pipelines. Inject steam, heat-conducting oil, cooling water, air-conditioning, etc. into the jacket according to user needs, so that the entire reduced-diameter heat-preserving ball valve can rise or fall to reach the required temperature and prevent the medium from crystallization. Wafer-type thermal insulation ball valves are mainly used in system pipelines in the chemical, petroleum, pharmaceutical, metallurgical and other industries. The main function is to transport the medium that will solidify and crystallize at room temperature. QB71F Wafer-type thermal insulation ball valve is welded with a metal jacket on the outside of the valve body, and the side and bottom of the thermal insulation ball valve are equipped with jacketed connection ports for steam in and out, so as to achieve the thermal insulation effect of the ball valve and ensure the stickiness The medium is circulating normally. Wafer-type thermal insulation ball valve has the characteristics of compact structure, small size, light weight, good sealing performance, flexible opening and closing, and convenient installation. Two-way insulation plug valve, also called jacketed plug valve, is based on the ordinary two-way plug valve, and a metal jacket is welded on the outside of the valve body of the plug valve. There are jacketed ports on both sides of the valve body, which can contain steam or other overheated gas to protect the medium in the valve from solidification or crystallization at room temperature. In the case of the same caliber, the connection size of the thermal insulation plug valve is one to two specifications larger than that of the ordinary plug valve. BX43W two-way thermal insulation plug valve is mainly used in various systems such as petroleum, chemical industry, metallurgy, and pharmaceuticals. The Y-type heat preservation filter is an indispensable heat preservation device used in water, oil, gas and other pipelines and various equipment. It is usually installed at the inlet of a pressure reducing valve, a pressure relief valve, a water level device or other equipment. Used to remove impurities in the medium to protect the normal use of valves and equipment. The Y-type heat preservation filter has the advantages of simple structure, low resistance and convenient sewage discharge. A metal jacket is welded on the outside of the valve body, and a jacket interface is provided, which can contain steam or other overheated gas to protect the medium in the valve from solidification or crystallization at room temperature. In the case of the same caliber, the connection size of the Y-type heat preservation filter is one to two specifications larger than that of the Y-type filter. The heat preservation discharge valve is also called the jacket discharge valve. It is divided into two types: upward expansion and downward expansion. A metal jacket is welded on the outside of the valve body, and a jacket interface is provided, which can contain steam or other superheated gas. To protect the medium in the valve from solidification or crystallization at room temperature. In the case of the same caliber, the connection size of the insulation discharge valve is one to two specifications larger than that of the ordinary discharge valve. The heat preservation discharge valve is an energy-saving valve in the boiler application system device. The product design is novel, the structure is reasonable, and the sealing performance is good.
