A sump pump system for a residential building has a sump with an inlet that receives water from an external source, a pump positioned with the sump, the pump having a pump inlet in fluid communication with the sump and an outlet in communication with a fluid destination, a valve connected to the inlet of the sump, the valve being movable between an open position in which fluid is permitted to enter the sump via the inlet, and a closed position, in which fluid is prevented from entering the sump via the inlet, wherein the valve is biased toward the closed position, and a valve restraint that is electrically actuated between a first state and a second state. In the first state, the valve restraint holds the valve open and in the second state, the valve restraint releases the valve.

One or more techniques and/or systems are disclosed for interrupting fluid flow when experiencing fuel leaking conditions, such as an out of specification connection between the fuel source and a device utilizing the fluid. A distal end of a valve body has interfaces with at least a portion of a connection to a fluid supply; and a proximal end interfaces with at least a portion of a fuel intake. An internal passage runs between the proximal end and distal ends of. A displacement member in the internal passage comprises a distal portion that extends out of the valve to engage a valve to the fuel supply. A retention cap selectably engaged with the valve body can comprise a material that deforms under force at a predetermined temperature, resulting in a release of the displacement member under a biasing force form a biasing component between the cap and displacement member.

The described methods and systems enable a control panel for a safety valve in a safety system of a process control environment to couple to a safety loop that couples a logic solver to a valve positioner for the safety valve. The control panel may drive a loop current on the safety loop to a desired range, thereby causing the valve positioner to respond by initiating a desired function triggered by the loop current entering the desired range. The desired function may be a trip function, a reset function, or a stroke test function.

The disclosure provides a vacuum storage tank, comprising a vacuum storage tank body. The vacuum storage tank body is provided with a storage cavity and a pressure release channel in communication with the storage cavity. The pressure release channel is provided with a pressure release structure, the pressure release structure includes a pressure release cylinder, and the pressure release cylinder is placed in the pressure release channel. The pressure release cylinder includes a manipulation part and a sealing member for blocking a port of the pressure release channel, and the manipulation part extends from an outer wall of the vacuum storage tank body. A reset retaining structure is arranged between the pressure release cylinder and the vacuum storage tank body to control the pressure release cylinder so that the sealing member keeps blocking the port of the pressure release channel.

In an embodiment, a system comprises a valve disc configured in an overpressure protection device. The system can also include a valve gasket configured to rest on the valve disc. The system also includes a valve seat configured above the valve gasket, wherein the valve gasket is sealed in between the valve seat and the valve disc. The system further includes a supporting structure configured above the valve seat. The supporting structure is configured to enable the valve gasket to remain in position between the valve disc and the valve seat in response to an increase in pressure.

A pressure relief apparatus for venting a tank comprising an inlet port, an outlet port, a closure member retained, relative to the inlet and outlet ports, for preventing, or substantially preventing, fluid communication between the inlet port and the outlet port, a trigger mechanism including a temperature response portion, and a compartment for receiving pressurized fluid from the outlet port and communicating the received pressurized fluid to the trigger mechanism. The trigger mechanism and the closure member are cooperatively configured to release the closure member and establish fluid communication between the inlet port and the outlet port, thereby venting the tank, upon detection of a temperature at or above a predetermined temperature threshold or upon pressurization of the compartment at or above a predetermined pressure threshold.
