　　燃气平板闸阀（直埋式闸阀，带放散管平板闸阀）密封面采用金属或者软型多层次密封圈结构，提高密封副抗介质中杂质破坏的能力，阀门全开或者全关时，密封副完全把管网通道与阀门腔隔离开来，阀座密封副完全被闸板覆盖，阻止了管网中的杂质，粉尘，焦油，以及气流对密封副的破坏和冲蚀，有效的保证了阀门的密封性能 retz the sealing surface of (with release) gas flat gate valveadopts metal or soft multi-level sealing ring structure to improve the sealingpair's ability to resist the damage of impurities in the medium. when the valveis fully opened or closed, the sealing pair completely separates the pipenetwork channel from the valve chamber, and the valve seat sealing pair iscompletely covered by the gate, preventing the damage and erosion ofimpurities, dust, tar, and air flow to the sealing pair, the sealingperformance of the valve is effectively guaranteed.

　　进口燃气平板闸阀 带放散管平板闸阀结构特点 structural characteristics

　　燃气平板闸阀全封闭结构，防护性能好，可适应全天候要求

　　1.开、关极轻便：阀座采用o形密封圈密封和施加预紧力的浮动阀座结构，使阀门进出口双向密封，真正达到零泄漏

　　2.双重密封：阀座采用密封面上镶嵌ptfe，具有ptfe对金属密封严密，同时ptfe密封面能自清除闸板脏物

　　3.注油脂结构：阀体外部设有注油脂结构，油脂通过注脂器、阀座进入阀门密封面，使阀门达到零泄漏

　　4.带导流孔结构：无论全开或是全关始终与密封面吻合，密封面得到保护不受介质直接冲刷

　　5.流阻小：阀门在全开时，通道平滑为直线，无压力损失，可通毛球清扫管线
