【供应进口气动保温球阀进口（手动、气动、电动）德国莱克LIK品牌】价格_厂家

进口气动保温球阀-德国莱克(LIK)品牌是由阿斯塔气动活塞式执行机构和夹层整体铸造阀体组成。阀芯为全球圆柱通孔球体。
该产品阀座设计成具有像弹簧一样的回弹作用而形成双挠性阀座，确保了球体密封的可靠性。同时介质压力与上游端挠性结构的回弹力又增加了下游端阀座的密封。挠性结构又自动补偿阀座的磨损及温度和压力变化，提高了使用寿命。
该产品具有易拆装维修、外形整洁、体积小巧、保温效果好等优点。能广泛应用于易结晶及粘稠的流体，并能满足各种需要保温介质的场合。如含蜡质、沥青较多的石油等被控介质，防止介质的结晶，确保自控系统高效运转。

QJ (D / S) RB O-intensive small air cut off valve insulation by pneumatic piston actuator Astana and laminated the whole cast body composition. Spool cylindrical hole for the global sphere.
The product is designed to have a seat like a spring rebound effect and the formation of double-flex seat, make sure the ball seal reliability. While medium pressure and the upstream end of the resilient and flexible structures to increase the downstream end of the valve seat seal. Flexible structure and automatically compensates for seat wear and the temperature and pressure changes, increased service life.
The products are easy disassembly and maintenance, neat appearance, small size, good insulation effect and so on. Easy to crystallize and can be widely used in viscous fluids, and insulation to meet the needs of media applications. Such as those containing wax, oil, asphalt more charged the media to prevent crystallization of the media, to ensure efficient operation of the automatic control system.
