Universal valve switch
View Patent ↗A universal valve switch for signaling the operative state of a valve assembly is disclosed that is attached to the body of the valve assembly using a bracketing arrangement. The valve switch comprises a housing defining a chamber and an aperture formed through the housing that communicates with the chamber. The valve switch may include a contact arrangement having a spring-loaded plunger that is extendable through the aperture with the plunger being operatively associated with the contact arrangement for selectively transmitting a signal to a remote panel whenever the lever is rotated out of contact with the plunger. In other embodiments, the contact arrangement may be replaced with various types of sensor assembly.
1. In combination, a valve switch and a valve assembly comprising:
a valve body defining a conduit adapted for selective fluid flow communication therethrough, said valve body including a valve member operatively connected to a lever for permitting fluid flow in an open position and preventing fluid flow in a closed position when said lever is rotated, said lever including a magnet directly attached to said lever; and
a magnetic sensor assembly, said magnetic sensor assembly being operatively associated with said magnet of said lever, said magnetic sensor assembly including a sensor such that said magnetic sensor assembly senses the presence or absence of said lever by said sensor;
a control module in communication with said magnetic sensor assembly, said control module capable of transmitting a signal when said lever is rotated such that said sensor does not sense said magnet directly on said lever.
2. The combination according to claim 1 , wherein said magnetic sensor assembly comprises a magnet in association with a reed switch or hail effect sensor.
3. The combination according to claim 1 , wherein said control module facilitates transmission of said signal when said lever is rotated to said closed position and said magnetic sensor assembly magnetic sensor assembly detects said magnet on said lever.
4. In combination, a valve switch and a valve assembly comprising:
a valve body defining a conduit adapted for selective fluid flow communication therethrough, said valve body including a valve member operatively connected to a lever for permitting fluid flow in an open position or preventing fluid flow in a closed position through said conduit when said lever is rotated; and
an optical sensor assembly, said optical sensor including a photocell in association with a lightsource, said optical sensor assembly being operatively associated with said lever such that said optical sensor assembly senses the absence of said lever when said photocell detects said lightsource; and
a control module in communication with said optical sensor assembly, said control module capable of transmitting a signal when said lever is rotated to the open position and said photocell detects said lightsource, while terminating said signal when said lever is rotated to said closed position and said photocell does not detect said lightsource.
5. In combination, a valve switch and a valve assembly comprising:
a valve body defining a conduit adapted for selective fluid flow communication therethrough, said valve body including a valve member operatively connected to a lever for permitting fluid flow in an open position or preventing fluid flow in a closed position through said conduit; and
a proximity sensor assembly, said proximity sensor being operatively associated with said lever such that said proximity sensor assembly senses the absence or presence of said lever, and
a control module in communication with said proximity sensor assembly, said control module being capable of transmitting a signal when said lever is rotated in said closed position and said proximity sensor assembly senses the absence of said lever, while terminating said signal when said lever is rotated in said open position and said proximity sensor assembly senses the presence of said lever.
