Insulation valve on the industrial production of a large number of valves to take good insulation measures, not only to obtain good energy-saving effect, but also can improve the safety and reliability of the valve to extend the service life of the valve. Insulation valve product line: insulation valve, insulation globe valve, insulation discharge valve, insulation valve and so on. Insulation valve is the valve body plus a layer of metal jacket of the general term for the valve, also known as jacket valve. Insulation valve types are: insulation valve, insulation shut-off valve, insulation butterfly valve, insulation plug valve, insulation filter, insulation discharge valve. Insulation valve is through the metal jacket into the steam, thermal oil, cooling water, air conditioning, so that the valve medium at room temperature, heating, cooling and other conditions to reach the required temperature, play a role in insulation or cold. Insulation valves in the petroleum, chemical, metallurgical, pharmaceutical and other systems are more applications, effectively reducing the heat loss of the pipeline medium, to prevent the crystallization medium, such as the appearance of solidification. Insulation butterfly valve, also known as jacket butterfly valve, is a common three eccentric metal seal butterfly valve on the basis of the outside of the body welded metal jacket, the butterfly valve in the body on both sides of the jacket with a jacket interface can contain steam or Other superheated gases prevent the media from solidifying or crystallizing at room temperature. Insulation butterfly valve flange than ordinary metal hard sealing butterfly valve to one or two specifications, mainly for petroleum, chemical, metallurgical, pharmaceutical and other systems. Other features can refer to the detailed parameters of the metal seal butterfly valve. Insulation valve, also known as jacket valve, is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other systems to transport high temperature medium will be solidified at room temperature. The series of valve jacket installed in the valve welding between the two flanges, the valve side, the bottom is provided with a jacket connector. Due to the increase of the jacket, the connecting flange of this type of valve is larger than the connecting flange of the same size ordinary ball valve by one to two specifications, but the structure length is the same as the valve of the same specification, and the jacket can freely flow through the steam Or other thermal insulation medium. Insulation shut-off valve, also known as jacket shut-off valve, is mainly used in chemical, petroleum, pharmaceutical, metallurgical and other industries in the pipeline system, the main role is to transport at room temperature will be solidified, easy to crystallize medium . BJ41W insulated shut-off valve welded between the two flanges metal jacket, the stop valve on the side and the bottom of the jacket set interface for injection of steam or other insulation, cold medium to ensure that the media valve to work properly. Insulation cut-off valve connection flange compared to the normal cut-off valve to one or two specifications. Reducing ball valve insulation has the characteristics of insulation, cold, mainly for petroleum, chemical, metallurgical, manufacturing and other industries. BQ41F Reducing Ball Valve Due to its steam jacket insulation, the BQ41F ball valve can be flexibly operated even if the outside temperature drops below zero, especially for heavy oil pipelines. According to the needs of users to the jacket into the steam, thermal oil, cooling water, air conditioning, etc., so that the entire shrink-diameter ball valve can warm or cool down to reach the desired temperature, to prevent crystallization of the medium. Wafer-type insulation ball valve is mainly used in chemical, petroleum, pharmaceutical, metallurgical and other industries in the system of pipelines, the main role is to transport at room temperature will be solidified, easy to crystallize the media. QB71F wafer-type insulation ball valve welded outside the body with a metal jacket, the side of the ball valve at the bottom of the jacket with a connection port for steam in and out, so as to play on the ball valve insulation, to ensure viscous Medium circulation is normal. On the folder insulation ball valve has a compact, small size, light weight, good sealing performance, flexible opening and closing, easy installation and so on. Two-way thermal insulation plug valve, also known as jacket plug valve, is a common two-way plug valve on the basis of the outer plug valve body welding metal jacket. In the valve body with two measuring jacket interface, can contain steam or other overheated gas to protect the valve medium will not be solidified or crystallized at room temperature. The same size caliber, insulation plug valve connection size larger than the average plug valve one to two specifications. BX43W two-pass insulation plug valve is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other systems. Y-type insulation filter is used for water, oil, gas pipeline and a variety of equipment indispensable to a kind of insulation device, usually installed in the pressure relief valve, pressure relief valve, water level gauge or other equipment inlet, Used to remove impurities in the medium to protect the normal use of valves and equipment. Y-type thermal insulation filter has the advantages of simple structure, small resistance and convenient drainage. The outside of the valve body is welded with a metal jacket and a jacket interface to contain steam or other overheated gas to protect the valve medium from freezing or crystallizing at room temperature. The same specifications of the diameter of the case, Y insulation filter size than the Y-filter to two sizes. Thermal discharge valve, also known as the jacket discharge valve, points on the show and show the next two, the body welded with a metal jacket outside the jacket, and a jacket interface, can contain steam or other overheated gas, To protect the valve medium will not be solidified or crystallized at room temperature. The same size caliber case, the insulation discharge valve connection size larger than the normal discharge valve to two specifications. Thermal discharge valve is an energy-saving valve in the boiler application system. The products of Nivei Valve Company are of novel design, reasonable structure and good sealing performance.
