衬氟法兰球阀

【概述】

衬氟球阀是用带圆形通孔的球体作启闭件,球体随阀杆绕阀体中心线旋转以实现阀门开启和关闭。采用特殊的模压工艺,使密封面致密良好,加之V型PTFE填料组合使阀门达到零泄漏;球体与阀杆铸为一体,杜绝了由于压力变化引起阀杆冲出承压件内的可能性,根本保证使用中的安全性;采用全塑料衬里工艺,耐介质的强腐蚀。

 

【结构特点】
衬氟球阀门结构为全通径浮动球式(二段式)和全通径固定球式(三段式)(小口径为两片式,大口径为三片式),主要用于截断或接通管路中的腐蚀性介质,并可用于流体的调节与控制,与其它阀类相比,有如下特点:
1.流体阻力小,衬里球阀内壁光滑,流道通畅是所有阀类中流体阻力最小的一种。
2.开关迅速、方便,只需将球体旋转90°,便完成开户和关闭动作。
3.采用特殊模压工艺,将衬里材料衬于阀门壳体内壁,能耐强酸、强碱介质的腐蚀。衬里球面与PTFE阀座组合,密封性好,达到了零泄漏。
4.可配置气动、电动、液动等多种驱动装置,实现远距离控制和自动化操作。
5.球体与阀杆融为一体,消除了转动角差,杜绝了因压力变化引起阀杆冲出体外的危险,保证了使用的安全性、可靠性。

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.
