　　优越的密封性能 Superior sealingperformance

　　燃气柱塞阀（天然气专用锥塞阀）的关闭组合(见柱塞阀结构图)是由一个不锈钢柱塞、上下两只富有弹性的密封环及能保持上下环固定距离的金属支架组成。柱塞象瓶塞一样插在两只密封环中。阀体与密封环、柱塞与密封环之间的密封力由联接阀体与阀盖的螺栓螺母提供，使它们彼此保持紧密贴合，形成瓶塞效果。密封面积远远大于普通截止阀，密封效果大大地优于普通截止阀The closing combination of gas plunger valve (natural gasspecialized cone plug valve) (see plunger valve structure diagram) is composedof a stainless steel plunger, two elastic sealing rings on the top and bottom,and a metal bracket that can maintain a fixed distance between the top andbottom rings. The plunger is inserted into two sealing rings like a bottlestopper. The sealing force between the valve body and the sealing ring, as wellas between the plunger and the sealing ring, is provided by the bolts and nutsconnecting the valve body and the valve cover, keeping them tightly attached toeach other, forming a cork effect. The sealing area is much larger than that ofordinary globe valves, and the sealing effect is greatly better than that ofordinary globe valves

　　进口燃气柱塞阀 天然气专用锥塞阀可靠的性能Reliable performance

　　柱塞阀的柱塞插入两只密封环中。插入下面一只密封环，截断了流道，实现了可靠的关闭。开启时，柱塞在虽然脱离下密封环，但仍然留在上密封环中，保持与外界隔离，不致发生泄漏。可靠的密封性能可以给您带来可观的经济效益：既不会浪费能源或原材料；也不会污染环境。

　　不在乎流体中的杂质 Don't careabout impurities in the fluid

　　流体中细微杂质不会伤害柱塞阀。当关闭阀门时，柱塞进入密封环中，会将流体中的悬浮微粒扫出去。
