An inductive shower head, comprising an outer shell which is provided with a water inlet and multiple groups of water outlet holes; a third water outlet cavity and a first water outlet cavity which are independent of each other inside the outer shell can be communicated with the corresponding groups of the water outlet holes respectively, a third water inlet cavity is arranged between the first water inlet cavity and the third water outlet cavity; the first water inlet cavity is communicated with the third water inlet cavity; the position where the third water inlet cavity is communicated with the third water outlet cavity is correspondingly provided with a control assembly which uses an electromagnet to control the two cavities to communicate with or block from each other; the shower head also comprises a first inductor and a power supply unit which is used for supplying power to the electromagnet.

The invention relates to a spool valve (1), having a valve housing (4) and a substantially axially symmetric closing body (3) arranged for longitudinal movement in the valve housing (4). An inlet channel (5), a first outlet channel (6a), and a second outlet channel (6b) are formed in the valve housing (4). The closing body (3) interacts with a first valve seat (8a) formed in the valve housing (4) by means of the longitudinal movement of the closing body and thereby opens and closes a first hydraulic connection between the inlet channel (5) and the first outlet channel (6a). Furthermore, the closing body (3) interacts with a second valve seat (8b) formed in the valve housing (4) by means of the longitudinal movement of the closing body and thereby opens and closes a second hydraulic connection between the inlet channel (5) and the second outlet channel (6b). The resulting hydraulic force on the closing body (3) in the axial direction is nearly zero.

A valve is provided having an inlet to receive a flowable particulate media and an outlet to dispense the media. The valve has an inlet portion with a funnel and repelling magnets. A shuttle sleeve extends from the inlet portion to allow a shuttle to slide along a central axis between an opened and a closed position. The shuttle has shuttle magnets that are oriented to have poles that face the repelling magnets to create a biasing force that biases the shuttle towards the closed position. When the shuttle moves, the shuttle magnets create eddy currents in a tube. The closed position is defined by a sealing edge of the shuttle contacting a sealing surface on a flow director. A capacitive sensor surrounds the flow director to measure the amount of media that is dispensed by the valve.

A fluid flow control device includes a valve body defining an inlet, an outlet, and a fluid flow path extending therebetween, a valve seat ring coupled to the body that defines an orifice through which the fluid flow path passes, a cage coupled to the body that defines an interior bore, a control element slidably disposed within the interior bore of the cage, and a particle catcher at least partially disposed within an interior bore of the control element. The particle catcher includes a particle catcher body that defines an inner flow path and at least one particle catcher passage through which the fluid flow path passes. An outer surface of the particle catcher and an inner surface of the control element form a particle catching portion. The at least one particle catcher passage directs the fluid flow path downwardly into the particle catching portion.

A regulator includes a body, a first cage positioned in the body, a diaphragm positioned within the body, and a second cage operatively connected to the diaphragm. The body has an inlet, an outlet, and a passage formed between the inlet and the outlet and the first cage is positioned adjacent the passage. The second cage moves with the diaphragm and is positionable on a first side of the diaphragm, opposite the first cage, or on a second side of the diaphragm such that the second cage is positioned within the first cage and is movable relative to the first cage.

Gate valve (1) with a valve casing (4) and a closing body (3) arranged longitudinally movably in the valve casing (4). An inlet channel (5) and an outlet channel (6) are formed in the valve casing (4). The closing body (3) via longitudinal movement cooperates with a valve seat (8) formed in the valve casing (4) and hence opens and closes a hydraulic connection between the inlet channel (5) and the outlet channel (6). The inlet channel (5) and the outlet channel (6) are each formed as a spiral.

Drain valves with rotatable angled outlets that can be rotated without allowing flow or stopping flow through the valve, containers including the valves, and methods of using the valves, are disclosed.

A normally closed subplate mounted valve has a lower valve seat defining a function port, an upper seat, and a sleeve between the upper seat and the lower seat. The sleeve defines a first port. The poppet is movable within the sleeve to selectively seal against the lower seat in a piloted position or to seal against the upper seat in an offset position. The poppet blocks the first port when the poppet is positioned in an offset position. A piston shaft is affixed to the poppet for moving the poppet into the piloted or offset position. A spring biases the poppet in the offset position for preventing fluid flow into the first port. A pilot port supplies pressure for sliding the piston to compress the spring and to move the poppet away from the offset position to the piloted position so that fluid may flow into a supply port and out of the function port. A second port may be provided in the sleeve. The ports may be selectively configured for supply or vent. Components may be joined with retainer springs. The piston shaft and poppet connector may be a key and key slot engagement. The ports may be shaped for progressive exposure by movement of the poppet. The poppet may be designed to enable pressure assist through the first port when moving the poppet to the piloted position. The valve seats may be provided with angled sealing surfaces that are angularly offset from their mating counterparts.

An in-line valve assembly for a tubular drag conveyer system includes a first tube segment having a first end and defining a first passageway, a second tube segment having a second end and defining a second passageway, and a tubular valve body translatably disposed relative to the second tube segment and defining a valve passageway. The first end of the first tube segment is spaced apart from the second end of the second tube segment by a gap. The valve body is selectively adjustable between a closed position wherein the valve passageway spans the gap and connects the first passageway to the second passageway and an open position wherein the valve passageway is spaced apart from the first passageway by at least a portion of the gap.

Anti-rotation assemblies for use with fluid valves are disclosed. An example apparatus includes a retainer collar coupled at an end of a plug, the plug including a plug collar around which the retainer collar is disposed, the plug and the retainer collar being substantially flush at an interface between the plug and the retainer collar, a fastener extending transversely through the retainer collar and the plug collar to couple the retainer collar at the end of the plug, when the retainer collar and the plug are disposed within a valve body, a stem extends through the retainer collar and the plug to enable the plug to be moved within the valve body; and an anti-rotation collar to receive the retainer collar, the anti-rotation collar coupled at an end of a cage, the anti-rotation collar and the retainer collar having corresponding non-circular cross-sections to inhibit rotation of the retainer collar and the plug when the plug is moved within the valve body.
