A liquid flow control valve having a valve seat and a valve plug for engaging said valve seat, said plug being connected to a pressure responsive device, such as a diaphragm, for movement therewith, said control valve being opened and closed by forces acting on opposite sides of said diaphragm, an anti-syphon valve located below said diaphragm for directing air into said flow control valve when a suction occurs at the inlet to said valve seat; said anti-syphon valve comprising an annular array of flaps which control the flow of air through openings in the body of said liquid flow control valve. Said flaps can be arranged to also provide a barrier to reverse flow from the liquid flow control valve exit through said valve seat to its inlet. Said liquid flow control valve can be of the pilot valve operated type or manually operated.

A rotary sprinkler in accordance with an embodiment of the present disclosure includes a riser with a nozzle assembly rotatable mounted thereon. The nozzle assembly includes a pressure regulator and flow control element.
摘要:
A double walled thermal container includes an outer container with an inner container mounted therein. Structural support is provided by an internal connection between the inner container and the outer container to minimize stress on the connection point. A separate elastomeric seal is preferably provided to prevent moisture from entering the area between the inner and outer containers.
