Insulation cut-off valve is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other kinds of systems, with flow of high viscosity medium will under normal temperature solidification, BJ45W dc insulation jacket insulation jacket of cut-off valve welding on the valve between two flanges, the side of the valve, set at the bottom of the heat preservation jacket two connectors. Dc insulation cut-off valve is especially suitable for chemical industry, chemical fertilizer pipe road, jacketed connotation into the steam can prevent the crystallization medium. Insulation cut-off valve is widely used in petroleum, chemical, metallurgical, pharmaceutical and other kinds of systems.
The working principle of globe valve
Cut-off valve, stop valve, Globe valve) of the opening and closing is plug valve, sealing surfaces appear flat or cone, disc make linear movement along the centerline of fluid. Stem form of exercise, (generic name: non-rising stem), also have lift rotating bar type, (generic name: stem) cut-off valve is closed a (disc) along the valve seat centerline mobile. According to this mobile form of disc, seat and disc change in his itinerary directly proportional relationship. Due to open or close the valve stem travel relatively short, and very reliable cutting function, and due to the change of his seat and disc stroke proportional relationship, is very suitable for the traffic regulation. Therefore, this type of valve is very suitable for as a cut or adjust and throttling.
