1) double sealing device
双密封装置
1.
This kind of sealing device is of double sealing devices,which has big and small discs with rubber and metal sealing rings installed.
该密封装置是一种分别在大小两个启闭件上均装有环形橡胶密封圈和环形金属密封圈的双密封装置,在阀门关闭时,阀板上的环形橡胶密封圈与阀座先接触形成一道密封;在环形橡胶密封圈被稍微压缩后,阀板上的环形金属密封圈再与阀座接触又形成一道密封并承受整个启闭件上的压力;而环形橡胶密封圈良好的弹性变形减轻了启闭件关闭件时的冲击力,具有一定的消声减震性。

补充资料:双锥密封
分子式:
CAS号:
性质:双锥密封是压力容器上常用密封,适用于设计压力为6.4~35MPa,设计温度为0~400℃,封口内径φ400~φ2000mm的压力容器。在密封面上垫有1mm左右的金属软垫片,靠主螺栓压紧,使软垫片塑性变形达到初始密封。为了增加密封的可靠性,在双锥面上还加工了二、三道半圆形沟槽。双锥环置于简体端部和端盖之间,借助托圈将双锥环托住,为便于装拆,托圈用螺钉固定在端盖的底部。端盖突台的侧面(即与双锥环的套合面)铣有几条较宽的轴向槽,以便容器内介质压力通过这些槽作用于双锥环的内侧表面,使双锥环径向扩张,起到径向自紧作用。由于其结构简单,加工容易,密封性能好,装拆方便等原因,在压力容器上广泛应用。缺点是端盖和连接螺栓尺寸较大。
