的详细信息

主要设计特点－Main Designing Features

· 整体式阀体设计，上装式枢轴固定支持。整体式枢轴固定球杆设计。

One piece body design, top entry trunnion support. One piece trunnion supported ball and stem design.

· 进口和出口双向密封功能

Seal on up-stream and down-stream sides of valve

· 双阻塞泄放功能

Double block and bleed function

· 高强度整体式球杆结构，确保球体在高压下具有正确的中心位置，保证阀门良好的操作性能

Heavy-duty one-piece ball and stem unit ensures central position of ball under the highest working pressure. This permits ease of operation.

· 阀盖与球杆有效接触，性能优越的防静电装置

Grounding device for positive anti-static contact between ball / stem and bonnet.

· 2组O型密封圈，加上阀杆上的防火填料结构，可有效防止泄漏

Two set of O-ring seals plus fire-safe packing on the stem efficiently prevent leakage

· 密封剂注入器设计，可在紧急状态下注入密封胶，对阀杆或阀座进行密封

Sealant injection fittings for emergency stem or seat sealing

· 预置驱动装置平台及螺栓孔，可随时装配驱动装置

Actuator mounting surface are machined and drilled, ready for mounting actuator

· 可选择的防火功能

Optional fire-safe function

· 符合NACE规范要求

All ball valves can be supplied in full compliance with NACE MR0175 Standard.

· 带弹簧的浮动阀座设计

A floating seat with spring design is provided.

·低压时阀座在弹簧预紧力的作用下，保证球与阀座间的低压密封

The preload of spring ensures bubble-tight sealing of ball and seat at low pressure.

·高压时阀座唇与球体全面接触，确保阀门的可靠密封性和较低的操作扭矩

At high pressure, the seat lip deflects slightly to ensure full seat-to-ball contact. This results in reliable sealing at high pressure and low operating torque.
