产品详情 Product details
五阀组包含两个隔离阀,一个平衡阀和两个排污阀,校验和测试,打开表压-平衡表压-检测压力表-泄放表压 The five valve group consists of two ***lation valves, one balance valve, and two drain valves, for calibration and testing, opening gauge pressure, balancing gauge pressure, detecting pressure gauge, and releasing gauge pressure
五阀组较三阀组的优点是随时进行仪表在线(现场)检查,效核,标定或排污冲洗,减少安装施工与效正费用,提高安装速度及质量。适用于仪表装置中与各种差压、流量、液位等变送器配套安装,它跟三阀组相同的是将差压变送器正、负测量室使引压点与测量室接通或断开The advantage of a five valve group over a three valve group is that it can conduct instrument online (on-site) inspection, verification, calibration, or sewage flushing at any time, reduce installation construction and efficiency costs, and improve installation speed and quality. Suitable for installation with various differential pressure, flow, liquid level transmitters in instrument devices, it is the same as a three valve group in that the positive and negative measurement chambers of the differential pressure transmitter connect or disconnect the pressure point from the measurement chamber
进口差压变送器五阀组主要特点DESIGN FEATURES
提供差压用途使用,适用于要求双向平衡+排放功能的差压变送器上
直接仪表安装和远程安装
配对两只截止阀、一只平衡阀和两只泄放阀
两截阀杆设计,上阀杆螺纹经滚牙硬化处理,下阀杆表面经特殊硬化
上阀杆螺纹的润滑脂与系统介质隔离
非旋转的下阀杆上下运动代替螺纹升降,减少每个行程对填料的磨擦,减少阀座和阀头之间的磨损
阀门在全开位置具有背密封功能
手柄采用两端螺钉锁紧,稳固耐用
阀组依据ASME B313和MSS-SP105标准来进行设计制造。
法兰设计参照MSS SP-99要求,也可提供满足IEC61518的法兰端口。
