摘要：
A differential dry pipe valve is provided having a body including an inlet chamber having an inlet port, an exit chamber having an exit port, and a gasket flange positioned between the inlet and exit chambers facing the exit port, the inlet and exit ports being substantially aligned. The valve also includes a gasket attached to the gasket flange and an openable cover hingedly attached to the body. The gasket has an inner water lip in fluid communication with the inlet chamber and an outer air lip surrounding the water lip. The spacing between the water lip and air lip varies. The air and water lips are coaxial. The cover is configured to be sealingly engaged with the seal when in a closed position and to be sealingly disengaged in an open position when the pressure in the exit chamber is lower than the pressure in the inlet chamber. When the cover is in the open position, a direction of a path between the inlet and exit ports is substantially unaltered.
摘要（中）：
一种差压干管阀，其具有主体，该主体包括具有入口的入口室，具有出口的出口室和位于所述入口和出口室之间面对出口的垫圈凸缘，所述入口和出口基本上 对齐。 阀还包括附接到垫圈凸缘的垫圈和铰接地连接到主体的可打开盖。 垫圈具有与入口室流体连通的内部水唇缘和围绕水唇缘的外部空气唇缘。 水唇和空气唇之间的间距变化。 空气和水的嘴唇是同轴的。 盖子被构造成当处于关闭位置时与密封件密封地接合，并且当出口室中的压力低于入口室中的压力时，盖子在打开位置被密封地分离。 当盖处于打开位置时，入口和出口之间的路径方向基本上不变。
