衬氟截止阀

【概述】

衬氟截止阀的启闭件是塞形的阀瓣,密封面呈平面或锥面,阀瓣沿流体的中心线作直线运动。阀杆的运动形式,有升降杆式(阀杆升降,手轮不升降),也有升降旋转杆式(手轮与阀杆一起旋转升降,螺母设在阀体上)。截止阀只适用于全开和全关,不允许作调节和节流。


【结构特点】
1、与闸阀相比,截止阀的结构较简单,制造与维修都较方便。
2、密封面不易磨损、擦伤,密封性较好、寿命长。
3、启闭时阀瓣行程较小,启闭时间较短、阀门高度较小。
4、阀瓣与阀杆设计为一体结构,结构紧凑,使用安全。
5、截止阀有三种结构形式:直通式、直流式、角式,其中直通式最为常用.角式可以安装在管路系统的拐角处,直流式流阻是截止阀中最小的。
6、根据用户需求配置气动、电动装置,满足遥控和程控的需要。
7、更换零件衬里材质可适用于各种介质。

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.
