产品详情 Product details
法兰式针型阀垂直升降式而非旋转升降式阀杆设计,避免阀门密封副间相对旋转产生刮伤及减少密封填料的磨损,有效地提高了阀门及填料的使用寿命,间歇式填料系统设计,有效地减少填料的冷流及阀门的操作力矩,同时可利用系统介质对填料的作用实现更好的密封 RETZ The flange needle valve is designed as a vertical lifting valve stem instead of a rotary lifting valve stem to avoid scratches caused by the relative rotation of the valve sealing pairs and reduce the wear of the sealing packing, effectively improving the service life of the valve and the packing. The intermittent packing system is designed to effectively reduce the cold flow of the packing and the operating torque of the valve. At the same time, the effect of the system medium on the packing can be used to achieve better sealing
进口法兰针型阀主要特点DESIGN FEATURES
设计符合ASME VIII,ANSI B16.34/B16.5B31.3 和API6D的相关要求
不旋转阀芯,以确保压力关闭的紧密性,不旋转阀杆承受超高压和超高温
阀体特殊的加强设计确保压力密封可靠性更高
填料位于阀杆的下方,以隔绝螺纹与介质的接触
阀杆螺纹为滚压制减少磨损长
手柄大大减少操作扭矩
阀杆和填料函接头和阀体是相扣设计,防止阀杆脱离阀门
