摘要： A fluid injection device includes a housing and a valve stem. The housing includes an inlet arm having an inlet orifice for receiving a feeder fluid. An outlet arm has an outlet orifice to discharge a mixed fluid. A venturi tube is between the inlet and outlet arms. The inlet arm, veturi tube and outlet arm define a nonlinear fluid pathway where the venturi tube redefines a portion of the nonlinear fluid pathway as a constricted fluid pathway. A diverter port is used to divert a portion of the feeder fluid from the inlet arm into the container and an injection port is used to receive product from the container. A valve arm is collinearly aligned with the venturi tube and the valve stem is positioned within the valve arm and adjusts the volume of the constricted fluid pathway.

摘要： A ceramic valve with a function of informing the operation position includes casing, a drive device partially and rotatably secured in the casing, a clicker longitudinally mounted to an upper portion of the casing and an outlet control device mounted to a lower portion of the casing for holding the drive device in place, wherein the drive seat extending through the clicker. The clicker informs an operation position by a “click” sound when the outlet control device is driven to a cold water supplying position, a hot water supplying position and a mixing water supplying position.

摘要： An apparatus according to which a subterranean formation in which a wellbore extends is hydraulically fractured, the apparatus comprising first and second manifolds, the first manifold including first and second flow lines adapted to be in fluid communication with first and second pumps, respectively, the first pump being adapted to pressurize fluid received from the first flow line, and the second pump being adapted to pressurize fluid received from the second flow line, and the second manifold including a third flow line adapted to convey pressurized fluid from the first and second pumps to the wellbore to hydraulically fracture the subterranean formation in which the wellbore extends. The apparatus is adapted to be connected to another apparatus used to hydraulically fracture the subterranean formation in which the wellbore extends by moving one, or both, of the first and second flow lines relative to the third flow line.

摘要： A water delivery system includes a mixing valve operable for delivering a water flow of adjustable temperature from a water source to a dispensing device downstream from the mixing valve; a thermochromic thermal indicator, fluidly coupled between the mixing valve and the dispensing device, that provides a visible indication of the water flow having achieved a predetermined temperature; and a diverter valve, fluidly coupled between the mixing valve and the dispensing device, and operable to direct the water flow selectively either to the dispensing device or back to the water source. The thermal indicator may be a thermochromic PVC conduit, or it may be a fitting having an inlet, an outlet, a thermochromic PVC element therebetween, and a barrier located between the inlet and the outlet so as to define a flow path that includes an interior surface of the thermochromic element.

摘要： Described herein is a fluid dispensing system, a system for processing waste material and a fluid monitoring system and a method of monitoring the quality of a fluid. One embodiment provides a fluid dispensing system (1) including a fluid dispenser (3) in fluid communication with at least one source of a first fluid. An identification device identifies a user of the system and generates a user identifier. A processor (19) is responsive to the user identifier to access a database (27) to retrieve user data indicative of one or more user preferences and, in response, generate a control signal. One or more electrical sensors (25) are configured to sense a gesture motion from the user and, in response, generate a local input signal. An actuator system (29) is responsive to the control signal and the local input signal to dispense the first fluid from the fluid dispenser with predefined characteristics.

摘要： The mixing unit for a mixer tap has a generally cylindrical shape defining a main axis and comprises a cartridge comprising a mixing chamber traversed by the main axis, wherein the mixing chamber comprises intakes of the incoming stream and an outlet for an outgoing stream. The mixing unit comprises means for mixing the incoming steams to form the outgoing stream contained in the mixing chamber, and an additional casing extending out of the mixing chamber. According to the invention, the mixing unit comprises a single-piece common part which delimits the mixing chamber, while forming at least a portion of the additional casing. The common part forms a separation wall between the cartridge and the additional casing, extending in a plane that is orthogonal to the main axis, wherein the intakes and the outlet are formed through the separation wall.
