    摘要： An adjustable valved coupler for drip irrigation line includes a valve body having a first end connected to a selector switch assembly and a second end having multiple outlets of differing sizes positioned eccentrically about the perimeter of the second end. The selector switch assembly has an inlet cap defining a main port for connecting an upstream feeder line to an internal volume of the valve body, a manually operable dial, and a circular seat mechanically linked to the dial by a shaft. The circular seat defines an eccentrically positioned aperture. Rotation of the dial moves the aperture into and out of alignment with the outlets to adjust flow rate. The selector switch assembly may also include an exit port to allow serial coupling to a downstream feeder line.

    摘要： A valve assembly includes a valve body defining an interior cavity extending to a bonnet portion, a valve stem including a valve element retained in the interior cavity of the valve body and an end portion extending beyond the bonnet portion, the valve stem being rotatable between first and second limit positions, and a spring return handle arrangement. The spring return handle arrangement includes a user graspable valve handle, a stem adapter, and a return spring. The stem adapter includes a first end portion secured to the valve stem and a second end portion secured to the valve handle. The return spring includes a first end portion secured to the valve body, an intermediate spring loaded portion, and a second end portion secured to the stem adapter to apply a torsional load to the stem adapter for returning the valve stem to the first rotational limit position.

    摘要： A wand assembly for an extraction cleaner which has a fluid delivery system and a fluid recovery system is disclosed. The wand body includes a fluid delivery pathway configured to receive a cleaning liquid via a delivery line and dispense the cleaning liquid through a distributor outlet. The wand body also includes a fluid recovery pathway configured to evacuate debris received via a working airflow pathway, and a fluid port fluidly connecting the fluid delivery and recovery pathways. A valve assembly is actuable between an inactive state, in which the valve assembly seals the fluid port and blocks a supply of fluid from the delivery line, to a delivery state, in which the valve assembly seals the fluid port and unblocks the supply of fluid from the delivery line, and a cleanout state, in which the valve assembly unseals the fluid port and blocks the supply of fluid toward the distributor outlet.

    摘要： Disclosed is a method for operating a valve (1), the method comprising the steps of locating an operating key system (2) at the valve (1), communicating a location of the operating key system (2) wirelessly to a central data system (3) from the operating key system (2), communicating a rotational direction to open or close the valve (1) wirelessly from the central data system (3) to the operating key system (2) based on the location, engaging operating means (5) of the valve (1) by means of an operating key (4) of the operating key system (2), rotating the operating key (4) manually towards an open or a closed position of the valve (1) while engaging the operating means (5) based on the received rotational direction to open or close the valve (1), detecting the direction in which the operating key (4) is rotated, wherein the direction of rotation is detected by means of rotation direction detection means (6) of the operating key (4), detecting if the valve (1) has reached the open or closed position, wherein the open or closed position is detected by means of end position detection means (7) of the operating key (4), and communicating the location, the direction of rotation and the open or closed position wirelessly to a central data system (3) from the operating key system (2). An operating key system (2) for operating a valve (1) and use of a method for operating a valve (1) buried beneath ground surface (18) is also disclosed.

    摘要： A regulating valve device for a fluid cylinder includes a shut off valve having a ball tappet that actuates the shut off valve. A lever has a cam surface that interacts with the ball tappet as the lever is rotated to translate the ball tappet linearly and actuate the shut off valve. The lever is rotatable from a first valve closed position through a valve open position to a second valve closed position such that the valve open position is intermediate of the first and second valve closed positions. A pressure or flow regulating valve is downstream of the shut off valve. A handwheel is operatively connected to the pressure or flow regulating valve to adjust an outlet pressure of the pressure or flow regulating valve. The handwheel has an axis of operation that is offset from a longitudinal axis of the fluid cylinder by an acute angle.

    摘要： A two-component rotary valve for controlling the fluid flow through a fluid conduit, the rotary valve being injection-moulded in two steps with no need for assembly after the injection moulding procedure. The rotary valve comprises a valve house with a plug inside it, and the rotary valve has sealing means in the form of local variations in the radius of the plug and house along their lengths. Thereby, a rotary valve is obtained which does not require a viscous sealant, such as silicone, to eliminate the risk of leakage, when the valve is open.
