Multifunctional restrictive valve

摘要

A multifunctional restrictive valve for controlling the flow of water therethrough. The valve has a main body with a flow channel through the main body. The main body receives water upstream thereof through an inlet port and passes it out through an outlet port at the downstream end of the body. A flow control assembly is located in the flow channel and includes a temperature sensor/actuator acting on a piston to move, when the temperature sensor heats up the piston, to block water flow control ports. The flow control assembly also includes an override feature wherein the piston is located within a slide and the flow control ports are located in the slide. By moving the slide away from the piston when the piston is blocking the flow control ports, the temperature sensor and piston may be overridden and flow may resume through the main body.

主权项

1. A valve for controlling a flow of water, the valve comprising:
a main body including a channel extending through the main body, the channel configured to receive water at an inlet port and pass water to an outlet port; and a flow control assembly in operative engagement with the channel, the flow control assembly including:
a temperature sensor configured to sense a temperature of water flowing through the channel; anda flow control member configured to control a flow of water in the channel responsive to the temperature sensor, the flow control member movable between a first position and a second position, where in when the flow control member is in the first position the flow control member is configured to allow the flow of water through the channel as a function of the temperature sensor, where in when the flow control member is in the second position water is substantially blocked from flowing in the channel;wherein the flow control assembly is configurable to allow water to flow in the channel regardless of the temperature of water flowing through the channel.
