    摘要: A dispenser assembly for controlled hydro-injection release of an erodible solid cartridge into a liquid. The dispenser assembly includes a fluid flow member with an inlet for attaching to a pressurized fluid line and an outlet. A hydro chamber with a hydro-injector member is provided in the fluid flow member. The hydro-injector member has an inlet opening which faces the inlet of the fluid flow member and outlet opening. A cartridge holding member is removably attached to the fluid flow member and is configured to house the erodible solid cartridge in an activation chamber. A plate is positioned in engagement with the hydro-injector member. An expandable member extends from the plate. The hydro-injector and the plate control the rate of erosion of the erodible solid cartridge.

    摘要: 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.
