排气/吹气连接
BLEED/BLOW CONNECTIONS
上面的桶状凸起部可钻孔攻丝，用来安装第二个排气阀和/或吹气阀连接。图示是这种排列的管路图。这也允许围绕阀塞的冲刷流体介质的循环。
An upper barrel boss may also be tapped for a
second bleeder and/or blow connection. A line drawing of this arrangement
is shown. This also permits circulation of a flushing medium around the
plug.
断面图说明环绕阀塞的阀体空穴。从阀塞上方和下方空间提供环流。
The sectional drawing illustrates the body cavities
surrounding the plug. Circulation is provided from the spaces above and
below the plug.
如果有必要与垂直向上不同的方式安装楔塞阀，则在处理滞留的固体时，建议对上部桶状凸起部进行钻孔攻丝。在安装阀门时，这个凸起部应该位于下方重力一侧。(对于特殊安装，请咨询工厂)。
If it is necessary to install Wedgeplug valves
in any position other than vertical when handling solids in suspension,
it is recommended that an upper barrel boss be tapped. In installing the
valve, this boss should be placed on the downward, gravity side. (Consult
factory for special installations.)
