  • Patent number: 10428963
    Abstract: A device and method to improve accuracy of a water meter where a fluid is introduced into a valve assembly having an external casing. The fluid contacts a toggle stopper having a shaft, plate, and guides. A calibrated spring positioned around the shaft in contact with the plate assesses if the desired fluid meets a predetermined pressure. If yes, the calibrated spring compresses thereby toggling the plate within the chamber to allow desired fluid to enter the chamber. If no, the calibrated spring remains in an expanded state to seal the valve assembly. Upon such seal, there is an equalizing of both the desired and undesired fluids to the same pressure by decreasing the volume of the undesired fluid, causing the calibrated spring to compress and reopen.

  • Publication number: 20150000769
    Abstract: The present invention relates to an anti-shake flow-limiting cutoff valve, comprising a flow stop valve, a cutoff valve and a check structure. Said flow stop valve comprises a valve body, a valve seat, a piston and a biasing component. The check structure is arranged downstream said flow stop valve to prevent fluid from flowing back. In case of a sudden excessive water flow, the flow stop valve is closed under impact of excessive water pressure to block the water flow. At this time, since the liquid flow in the pipeline is suddenly blocked, the liquid flow remaining in a pipeline downstream the flow stop valve tends to form a reverse flow to impact the flow stop valve, thus shaking the flow stop valve, which may further lead to insufficient close or damage of the flow stop valve.

  • Patent number: 7591291
    Abstract: A fuel receiver assembly, that permits replacement of a worn fuel receiver without draining the fuel tank, includes a check valve receptacle having a male-pipe-threaded nipple which engages the female-threaded pipe coupling of the fuel tank. The check valve receptacle has a spring-biased, normally closed check valve that prevents fuel from escaping from the fuel tank. Fuel pressure from the refueling pump opens the normally-closed check valve. The check valve receptacle is designed to be a relatively permanent installation in the fuel tank, having ultra-low-wear components. The check valve receptacle also has a female-threaded socket that is coaxial with the male-pipe-threaded nipple. A specially-designed male-threaded fuel receiver engages the female-threaded socket. Sealing between the check valve receptacle and the replaceable fuel receiver is accomplished by an O-ring seal installed on the fuel receiver.
