Abstract
A system for pumping of liquid under pressure, in which a pressure switch is adapted to control the starting and stopping of the pump within a safe pressure range, and in the event of malfunction of the pressure switch, the service line and associated plumbing is isolated from the pump to protect against development of pressures in the serviceline which might damage the plumbing.
Claims2
A pressure regulating valve assembly comprising a housing having an input opening for receiving liquid under pressure, an outlet opening for discharging such liquid at a reduced pressure, and a valve component and associated valve seat component intermediate said inlet and outlet openings and in the flow path between them, one of said components having a notch in a surface facing the other component, and said other component including a disc of compressible material and a solid backing for said disc to preclude flexing thereof while enabling compression of said disc upon closing of said valve component upon said seat component, said notch being of a depth such that upon closing of said valve upon said valve seat, said disc material will compress into and fill said notch to block flow therethrough.
