Introduction to insulation valve

The heat preservation valve adopts good insulation measures for a large number of valves in industrial production, which not only can obtain good energy-saving effects, but also can improve the safety and reliability of the valve and prolong the service life of the valve.
Insulation valve product series: heat preservation gate valve, heat preservation stop valve, heat preservation discharge valve, heat preservation ball valve, etc. Yangzijiang various industrial applications valves provide insulation valve series. Welcome to buy and consult. The heat preservation valve is a general term for a valve that adds a metal jacket to the outside of the valve body, and is also called a jacket valve. The types of heat preservation valves are: heat preservation gate valve, heat preservation stop valve, heat preservation butterfly valve, heat preservation plug valve, heat preservation filter, heat preservation discharge valve and the like. The heat preservation valve is formed by injecting steam, heat transfer oil, cooling water, cold air, etc. into the metal jacket, so that the medium of the valve body reaches the required temperature under the conditions of normal temperature, temperature rise, temperature drop, etc., and plays the role of heat preservation or cold preservation. Insulation valves are widely used in various systems such as petroleum, chemical, metallurgy, and pharmaceuticals, effectively reducing the loss of heat in the pipeline and preventing the appearance of crystals and solidification of the medium. Insulation butterfly valve, also known as jacketed butterfly valve, is a metal jacket welded on the outside of the valve body on the basis of the ordinary three eccentric metal hard sealing butterfly valve. The valve body is installed on both sides of the valve body of the thermal insulation butterfly valve, which can be immersed in steam or Other superheated 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 the ordinary metal hard sealing butterfly valve, and is mainly used in various systems such as petroleum, chemical, metallurgy and pharmaceutical. Other features can be found in 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 medium that will solidify at room temperature. The jacket of the series of valves is welded between the two flanges of the valve, and the connecting port of the jacket is arranged on the side and the bottom of the valve. Due to the addition of the jacket, the size of the connecting flange of the valve is one to two sizes larger than the connecting flange of the common ball valve of the same specification, but the structural length is the same as that of the valve of the same specification, and the steam can freely flow through the jacket. Or other thermal insulation medium. Insulation stop valve, also known as jacketed shut-off valve, is mainly used in system piping of chemical, petroleum, pharmaceutical, metallurgical and other industries. Its main function is to transport medium that will solidify and crystallize under normal temperature. . BJ41W insulation stop valve is equipped with a metal jacket between the two flanges. A jacket interface is provided on the side and bottom of the shut-off valve for injecting steam or other heat preservation and cooling medium to ensure the normal operation of the medium inside the valve. The connection flange of the heat preservation shut-off valve is one to two specifications larger than the ordinary shut-off valve. The reduced diameter thermal ball valve has the characteristics of heat preservation and cold preservation, and is mainly used in petroleum, chemical, metallurgy, manufacturing and other industries. BQ41F reduced-diameter thermal ball valve adopts steam jacket insulation, so it can operate flexibly even if the outside temperature drops below zero, especially suitable for heavy oil pipeline. According to the user's need to inject steam, heat transfer oil, cooling water, cold air, etc. into the jacket, so that the entire reduced diameter heat preservation ball valve can be warmed or cooled to achieve the desired temperature to prevent the medium from crystallizing. The clamp type thermal insulation ball valve is mainly used in the system pipelines of the chemical, petroleum, pharmaceutical, metallurgical and other industries. The main function is to transport the medium which will solidify and crystallize under normal temperature conditions. The QB71F wafer type thermal insulation ball valve is welded with a metal jacket on the outside of the valve body, and a jacketed connection port is arranged on the side and bottom of the heat preservation ball valve for the steam in and out, thereby maintaining the heat preservation effect on the ball valve and ensuring the viscosity. The media is circulating normally. The clip type heat preservation ball valve has the characteristics of compact structure, small volume, light weight, good sealing performance, flexible opening and closing, and convenient installation. The two-way heat-insulation plug valve, also known as the jacket-type plug valve, is based on the ordinary two-way plug valve, and the metal jacket is welded on the outside of the plug valve body. The valve body is equipped with a jacket interface to contain steam or other superheated gas to protect the medium in the valve from solidification or crystallization at normal temperature. In the case of the same size, the connection size of the insulated plug valve is one to two larger than the normal plug valve. BX43W two-way insulation plug valve is mainly used in various systems such as petroleum, chemical, metallurgy and pharmaceutical . Y -type insulation filter is an insulative device for water, oil, gas and other pipelines and various equipment. It is usually installed at the inlet end of pressure reducing valve, pressure relief valve, water level device or other equipment. It is used to remove impurities from the media to protect the normal use of valves and equipment. Y -type thermal insulation filter has the advantages of simple structure, small 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 be filled with steam or other superheated gas to protect the medium in the valve from solidification or crystallization at normal temperature. Case of the same size diameter, Y-type filter is connected incubated one size larger than the size to the two Y-strainer. The heat preservation discharge valve is also called the jacket discharge valve. It is divided into two types: upper and lower display. The 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. The medium in the protective valve does not solidify or crystallize at normal temperature. In the case of the same size, the connection size of the heat preservation discharge valve is one to two specifications larger than the ordinary discharge valve. The heat preservation discharge valve is an energy-saving valve in the boiler application system device, and the product has novel design, reasonable structure and good sealing performance.
