Abstract: A limit switch for a rising-stem type valve which has a spring-loaded actuator arm with a bracket on one end which wraps around the valve stem. A follower or roller on the end of the bracket opposite the actuator arm rides on the rising stem of the valve, held in contact with the stem by the spring.

This causes the spring to bias the actuator arm to move a tab at the opposite end of the actuator arm, and the tab operates a limit switch.

Abstract: The present invention relates to a sprinkler with an integrated valve, and to a fire-extinguishing system using same. Conventional sprinklers are too sensitive to the outbreak of a fire, and operate even if no fire has broken out, which would lead to a large amount of damage. For this reason, conventional sprinklers are often prevented from being operated in advance. In addition, sprinklers do not operate even upon the outbreak of a fire when the sensitivities thereof are lowered, rendering the sprinklers useless.

Abstract: A sprinkler system comprises a network of CPVC conduits and a plurality of sprinklers. The system includes an electrically activated solenoid control valve to allow fluid to flow in the pipe network. One or more fire detectors operate independently of the condition of the sprinklers. Upon detection of an incipient fire situation, a fire detector sends an electrical signal to cause activation of the control valve. Upon activation of the control valve, fire suppression fluid is caused to flow through the conduits before the incipient fire situation matures into a sprinkler-triggering event. The cooling effect of fluid flowing through the conduit enables the conduit to resist structural failure prior to sprinkler deployment. The control valve may be disposed at a remote location in the sprinkler line and be operable as part of an inspector's test connection.
