密封填料系统，确保长久密封
Packing System Ensures Long-Life Seal
美国DeZurik（德朱瑞克）KGC阀门独特的密封填料系统能够在最小密封填函料压力下，实现长久的紧密密封。这种密封填料系统可应用在一般应用环境、严酷应用环境和高温应用环境。机加工填料腔和防推出密封环形成这种密封填料系统。这种系统采用精心选择的密封填料组成。温度、酸碱度pH值以及流体介质特性都决定密封填料材质的选择。
DeZurik KGC Valves have a unique packing system
that ensures a long-life tight seal with minimal packing gland pressure.
The packing system is available for general, moderate, severe and high
temperature applications. The machined packing chamber and an anti-extrusion
ring form the base of this system. The system is completed by careful
selection of the packing material. The temperature, pH, and media properties
will determine the most suitable option.

防推出密封环规范闸板运动方向，有助于密封填料实现更好的工作状态，当闸板运动时减少摩擦和作用力。
Anti-extrusion ring guides the gate, makes the
packing work better, reduces friction and acts as a gate wiper. |
