ZJHRJ 保溫夾套O型球閥是ZJHR O型球閥的派生產品，除具有ZJHR 球閥相同的用途外，主要應用于保溫場合。當工藝介質的結晶溫度低于環境溫度或流體溫度降低，造成粘度增加或流體出現凝固時，在球閥的閥體外側增設保溫夾套裝置，通以蒸汽達到加溫和保溫的目的，使工藝過程按要求進行下去。它廣泛應用于石油、化工、冶金、電站等自動控制系統中，對流體輸送管道中的介質進行切斷或接通。
Insulating jacket Type O Ball Valve
ZJHRJ Insulating jacket type O ball valve is the derivative product of ZJHR type O ball valve. Besides the similar service as ZJHR, it is mainly used for thermal retardation. The insulating jacket outside of the body can be on the purpose of heating and insulation, so that the process continues as required when the crystallizing point of the medium lower than the ambient temperature or the fluid temperature reduced resulting in viscosity increase or solidification emergence. It is widely used in automatic control system such as petroleum, chemical industry, metallurgy and power station, etc. to on-off medium in delivery pipeline.
