锻钢螺纹截止阀

锻钢螺纹截止阀是指采用锻造钢材制造,通过螺纹连接方式与管道相连的截止阀,主要用于截断或接通管路中的介质。


结构特点

阀体材质:采用锻造钢材,如 A105 碳钢、304/316 不锈钢等,质地紧密、强度高,能承受高压与恶劣工况。

连接方式:通常采用 NPT、G 或 PT 等螺纹连接方式,便于安装和拆卸,适用于小口径管道。

阀盖设计:有螺栓式阀盖、焊接式阀盖和自密封阀盖三种形式,可根据不同的工况和密封要求选择。

阀瓣与阀座:阀瓣与阀座的密封面经过精密加工,采用金属对金属密封或辅以密封垫片,密封性能好,能有效防止流体泄漏。


工作原理

通过旋转阀杆带动阀瓣上下运动,从而控制流体的通断。当阀瓣上升时,流体可以通过阀座与阀瓣之间的间隙流出;当阀瓣下降与阀座紧密贴合时,流体被截断。

Products and services that meet fluid control requirements

Each process, each facility, and each environmental constraint has its own special requirements. Therefore, Dongyan offers a comprehensive range of products covering different performance levels, pressures, different functions and different materials.

Product Application Scope

These devices are suitable for accurately controlling media such as gases, liquids, steam, etc., and maintaining process parameters such as pressure, flow rate, temperature, and liquid level at given values. Especially suitable for work environments where the allowable pressure difference is small and the allowable leakage is also small, and the pressure difference is not significant.
