摘要： An improved automatic air pressure relief and check valve assembly which may be used in combination with a swimming pool filter tank or a swimming pool separation tank. The valve assembly includes a normally open lower valve which communicates with the inside of the tank and is responsive to the tank's being full of pressurized water for closing the lower valve. The valve assembly further includes a normally closed upper valve communicating with the lower valve and the outside of the tank, the upper valve being responsive to air being expelled from the tank through the open lower valve, when water is filling the tank, for opening the upper valve to permit the air being expelled to exit through the upper valve. Cooperating with the upper and lower valve of the improved valve assembly is means for precluding both the upper and the lower valves from being simultaneously maintained in their closed conditions. Associated with the normally closed upper valve is selectively actuable means responsive to an externally applied force for opening and maintaining open the upper valve while the force is applied during selected times when water is not entering the tank, for permitting air to enter the tank so that water may be drained from the tank when desired.
摘要翻译：改进的自动空气压力释放和止回阀组件，其可以与游泳池过滤罐或游泳池分离罐组合使用。阀组件包括常开的下阀，其与罐的内部连通并且响应于罐充满加压水以关闭下阀。阀组件还包括与下阀和罐的外部连通的常闭上阀，当阀正在充满油箱时，上阀响应于通过打开的下阀从油箱中排出的空气，以打开上阀门允许空气排出通过上阀门排出。与改进的阀组件的上下阀配合是用于排除上下阀门同时保持在其关闭状态的装置。与通常关闭的上阀相关联的是选择性致动装置，其响应于外部施加的力来打开和保持打开上阀，同时在水未进入油箱的选定时间期间施加力，以允许空气进入油箱，使得当需要时，水可以从罐中排出。

摘要： An automatic air pressure relief and check valve assembly which may be used in combination with a swimming pool filter or separation tank. The valve assembly includes a normally open lower valve which is responsive to the tank's being full of water for closing the lower valve, and a normally closed upper valve which is responsive to air being expelled from the tank through the normally open lower valve for opening the upper valve during times when water is filling the tank. The upper valve may be selectively opened when air is required to enter the tank so that water may be drained from the tank. Preferred embodiments of the upper and lower valves include valve seats having conical surfaces and respective valve members which cause an included O-ring to roll upon and wedge against its conical seat for reliably closing each valve.
