摘要： An air admittance valve preventing mephitis overflow, having a main body with an air entry guide base defining an air entry guide; a pivot support; and a valve seat. A sealing valve group having a sealing valve body that defines a recess; a flexible member; a pivot housing; and a pivot. The valve seat is located about the air entry guide. The pivot is located in the pivot housing and the pivot support, and the pivot is located along, or adjacent to, the center of gravity of the sealing valve body. The flexible member is at least partially located in the recess and abuts the main body; and when the air admittance valve is closed, the sealing valve body abuts the valve seat.

摘要： A system and parts of a system that can be used to introduce fluid into a closed circuit. The system includes a valve having an inlet, an outlet, a flush inlet; a spool located in a valve body and coupled to a handle, and the spool can selectively, by the positioning of the handle, direct flow between the inlet, outlet, and flush inlet. The system also includes an uptake conduit comprising a valve connector that is configured to couple with the flush inlet, and a conduit, that is configured to allow fluid to flow therethrough. Additionally, the system has a system attachment having a system connector and a valve connector, and the uptake conduit and the system attachment are coupled to the valve.

摘要： A bypass system for a water heat exchanger is disclosed. The water heat exchanger has a water heat exchanger inlet attached to a feed valve and a water heat exchanger outlet attached to an exit valve. The feed valve and the exit valve are three-way bypass valves attached to a bypass line. When the feed valve and the exit valve are in the flow through position, fluid will flow into and out of the water heat exchanger. When the feed valve and the exit valve are in the bypass position, fluid will not enter nor exit the water heat exchanger, but fluid will flow through the bypass line.
