  • Patent number: 9435449
    Abstract: Concepts and technologies disclosed herein for relief valves (“relief valves”). A relief valve can include a flow path, a primary valve poppet that is urged or biased into a closed position by a tensioned spring, and a pilot valve in communication with a valve compartment of the relief valve. When an exterior space pressure overcomes the tensioned spring, the primary valve poppet can be overcome and pressure between an interior space and the exterior space can equalize, at least partially. When the pressure within the interior space increases beyond a defined threshold, which can be defined by a spring of the pilot valve, the pilot valve can open, the valve compartment can vent, and the tensioned spring again can be overcome and can open to allow at least partial equalization of pressures within the interior space and the exterior space.

  • Patent number: 6938637
    Abstract: A gas meter installation including gas supply plumbing and point of use plumbing will have a gas meter therebetween. A valve can be installed with the gas meter for shutting off the flow of gas to the point of use. This valve is preferably a gate valve mounted with the a gas meter, and can be retrofitted into existing installations, or installed with the new plumbing installation. The valve can be shut off by remote activation for example due to a seismic sensor causing a controller to send a signal to activate the valve. The control can also interact with electricity shut off apparatus, automatic meter reading apparatus and point of use security systems.

  • Patent number: 6926025
    Abstract: A vertical shock responsive fluid valve assembly capable of automatically closing a fluid valve in response to earthquake forces or other shock forces of a predetermined magnitude. The vertical shock responsive valve assembly has a flow control mechanism having a cradle that holds a movable ball in a recess at a point perpendicular in relation to a horizontal base plate, where the ball can be rotated 360° in any direction during seismic actions or other shock forces and rolls out of its recess at a predetermined force such that it ricochets off a housing cover covering the cradle and pushes a trip fork mechanism having elongated walls to provide additional leverage when the force strikes the trip fork mechanism that is mounted on a pivoting mechanism, thereby releasing a swing arm which has a disc on the end that functions as a plug for the hole in the valve body to interrupt gas or fluid flow therein.

  • Publication number: 20040211462
    Abstract: A microprocessor-based gas meter has fully electronic control, safety cutoff and data communication functions, while remains the same size of a conventional gas meter. The control circuit board in the microprocessor-based gas meter is mounted inside the main body of the gas meter through a mounting slot. The sensors, wires and battery are located in the rest space of the chamber so as to utilize the space of the chamber. When an abnormal situation is detected, the control circuit activates a cutoff valve and shuts off the gas intake. The data communication function is to transfer gas-metering data through telephone lines to the gas company so that the mistakes and cost of manual checking and recording can be eliminated.
