产品详情 Product details

内螺纹针型阀仪表阀，压力表阀两端为G、NPT内螺纹连接,与管道外螺纹对接,具有受压大、严密的密封性能,通常用在较小流量,较高压力的气体或者液体介质的开通、断流、节流Internal thread needle valve instrument valve, with G and NPT internal thread connections at both ends of the pressure gauge valve. It is connected to the external thread of the pipeline and has high pressure and tight sealing performance. It is usually used for opening, cutting off, and throttling gas or liquid media with small flow rate and high pressure

进口内螺纹针型阀设计标准 Design standards

针型阀门设计可以确保在苛刻的环境下使用阀体特殊的加强设计确保压力密封可靠性更高。

阀体和阀盖中使用的特殊材料垫片适用于临界电站

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

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
