  • Patent number: 10920891
    Abstract: Valve assemblies with butterfly valves for use as a double isolation & bleed (DIB) valve and a double block & bleed (DBB) valve. The embodiments may have a twin-disc design with a non-separable, valve body having a central bore. A pair of butterfly valves may reside in the central bore, each having an annular seal and a rotatable disc that contacts the annular seal to prevent flow of fluid into space between the butterfly valves. Implementations of the embodiments configure the annular seal with a sloped contact surface at an angle to positively seal the rotatable discs in the preferred direction of incoming flow. In this way, the valves can always close in response to either uni-directional flow into one end of the central bore or bi-directional flow into both ends of the central bore, respectively or simultaneously.

  • Patent number: 10914386
    Abstract: An object of the invention is to provide a method of controlling a gate valve that operates the gate valve in a short time while suppressing vibration of the valve body. A method of controlling a gate valve provided on an opening of a chamber, wherein the gate valve includes a valve body that opens and closes so as to close the opening of a chamber, a valve seat provided on the edge of the opening to which the valve body is pressed, and a sealing material for sealing between the valve body and the valve seat. The invented method is characterized in that, in moving the valve body to the open position from the closed position where the valve body is pressed against the valve seat with the sealing material compressed, the valve body is made to stop temporarily for a predetermined time at the position immediately before the compressed sealing material is pulled apart or immediately after pulled apart in the opening movement of the valve body.

  • Patent number: 10877494
    Abstract: A method for depressurizing a pipe includes forming, by an ejector assembly, a seal between a first pipe and a second pipe fluidically coupled to the tee pipe fitting. The first pipe flows a first fluid at a first pressure, and the second pipe flows a second fluid at a second pressure lower than the first pressure. The ejector assembly includes a nozzle converging along a flow direction of the first fluid flowing in the first pipe, and a mixing chamber at an outlet of the nozzle, the mixing chamber comprising an outlet is in fluid communication with the second pipe. The method also includes flowing the first fluid from the first pipe into the ejector assembly through the nozzle so that the pressure of the first fluid decreases to a third pressure lower than the second pressure to draw the second fluid into the mixing chamber.

  • Patent number: 10876688
    Abstract: The present invention generally relates to the production of fluidic droplets. Certain aspects of the invention are generally directed to systems and methods for creating droplets by flowing a fluid from a first channel to a second channel through a plurality of side channels. The fluid exiting the side channels into the second channel may form a plurality of droplets, and in some embodiments, at very high droplet production rates. In addition, in some aspects, double or higher-order multiple emulsions may also be formed. In some embodiments, this may be achieved by forming multiple emulsions through a direct, synchronized production method and/or through the formation of a single emulsion that is collected and re-injected into a second microfluidic device to form double emulsions.
