Abstract
A fluid routing device has a sealed self-contained body which includes all of the working parts of such a device is combined with a base plate having discharge ports which register with outlets in the sealed body which are controlled by valves within that body, means for sealingly, but releasably, attaching the base plate to the body and the body to the conduit to a source of fluid under pressure are also included. The disclosure also teaches a method of servicing devices in a swimming pool system including the steps of providing in the device a sealed self-contained releasable body portion containing the moving parts, removing a malfunctioning sealed body portion and replacing it with a new functioning sealed body portion.
Claims6
In a fluid routing device including:
- a. a hollow body including at least two exterior parts comprising upper and lower segments joined together to make a self-contained, unitary body, and having
- (1) inlet means for the admission of fluid;
- (2) a plurality of valve means having open and closed positions relative the outward passage of fluid;
- (3) means responsive to the flow of fluid for sequentially opening and closing said valves;
- b. a base plate adapted to attachment to said lower segment and having a plurality of outlet means registering with and controlled by said valve means;
- and
- c. means for releasably attaching said body to said base plate, each of said plurality of valve means comprising a casing, a diaphragm disposed within said casing, a valve plug suspended within said casing by means of said diaphragm, a port in said lower segment having a valve seat, said plug having a valve face sized and adapted to register with and seal on a portion of said seat, whereby tolerance is increased and positive seating enhanced.
