A fluid control valve includes a cover portion and a body portion. Inner surfaces of the cover and the body portion define a chamber that includes an inlet and an outlet in communication with the chamber. The cover portion includes a central section and an inversion inhibitor circumscribing the central section. The inversion inhibitor projects into the chamber toward a central axis of the chamber. The fluid control valve also includes a diaphragm disposed between the cover portion and the body portion. The diaphragm has a flexible member that is disposed within the chamber for controlling communication between the inlet and the outlet. The inversion inhibitor prevents the flexible member from reaching its natural-inverted position and creates a force within the flexible member that urges the flexible member to a seated position. In the partially inverted position, the upper surface of the flexible member conforms to at least a portion of the inner surface of the cover portion to define a passageway that permits communication between the inlet and the outlet.

An outlet valve includes a valve body, a solenoid valve, and a manual operating member. The valve body includes a water inlet, a water outlet, a water storage cavity, a drain waterway, a first waterway, a second waterway, and a waterproof membrane. The first waterway is coupled to the drain waterway through a first drain opening. The second waterway is coupled to the drain waterway through a second drain opening. The waterproof membrane is configured to separate the water outlet cavity from the water storage cavity. The first waterway comprises a first plug coupled to an output end of the solenoid valve. The first plug is configured to control the opening and closing of the first drain opening. The second waterway comprises a second plug coupled to the manual operating member. The second plug is configured to control the opening and closing of the second drain opening.

A laminar stream reactor for the production of hydrochar of a solid-fluid mixture of water and a carbon-containing component, wherein the solid-fluid mixture is treated at a temperature of 100-300 degree ° C. and a pressure of 5-70 bar, consists of tubular reactor units of largely vertical holding sections (1,3) and direction-changing diverters (2,4). The holding sections are thereby flown through slower by the solid-fluid mixture than the remaining tube distances, as they have larger diameters.

A valve with a controlled closing system includes housing having an inlet port, a liquid outlet port, and an inlet chamber. A pressure responsive closing mechanism is disposed between the inlet port and the liquid outlet port. A control chamber is in fluid communication with the inlet chamber via a fluid passage. The fluid passage includes a controlled closing system for controlling opening and closing of the fluid passage. The controlled closing system includes a seal movable with respect to and sealable against an opening of the fluid passage.

A valve (1) for a sanitary faucet, comprising: a liquid duct (2) having at least one inlet (3) and at least one outlet (4) for a liquid; a diaphragm valve (5) having a diaphragm (6) and a counterpressure chamber (7) connected to the at least one inlet (3); and a control rod (8) for controlling the diaphragm valve (5), wherein a push button (9) can be used to adjust the control rod (8) between a closed position, in which the diaphragm valve (5) is closed, and an open position (10), in which the diaphragm valve (5) is at least partially open, wherein a rotary handle (11) can be used to adjust the control rod (8) in the open position (10) between a minimum flow position (12), in which a minimum flow rate of the liquid flows through the at least one outlet (4), and a maximum flow position (13), in which a maximum flow rate of the liquid flows through the at least one outlet (4), and wherein the minimum flow position (12) of the control rod (8) can be variably adjusted.

Some embodiments include a valve assembly with a metering seal including a main channel including regions with a first diameter and regions with a second diameter, where the first diameter is smaller than the second diameter. Some embodiments include a stem positioned in the metering seal extending from at least a first end of the metering seal to a second end of the metering seal. In some embodiments, the stem has a fluted section positioned between two non-fluted sections, where the diameter of stem in the fluted section is smaller than the diameter of the stem in the non-fluted sections. Some embodiments include a first and second flow channel extending across at least a partial width of the metering seal, where the first flow channel is positioned at the first end of the metering seal, and the second flow channel is positioned at the second end of the metering seal.

In the case of a valve-actuating device (1), it is provided that, between a manual operating element (2) and a control element (4), by which a valve (3) can be adjusted between an open position and a closed position, there is formed a compensating device (6) by which the control element (4) can be moved relative to the manual operating element (2), and toward or away from the latter, counter to a restoring force of a restoring element (9), wherein the restoring element (9) is arranged outside the compensating device (6), and/or a plunger (8) is arranged on the control element (4) and is guided in a receptacle (7) of the compensating device (6), wherein there is additionally or alternatively formed an adjusting device (34) by which the control element (4) can be moved away from or toward the manual operating element (2) (FIG. 1).

Provided are valve devices and flow heads for a valve device. A valve device can include a valve body (30) that opens and closes a valve hole (15a) to allow communication between a primary flow path (17a) and a secondary flow path (17b), a back pressure chamber (7) defined at the back side of the valve body, a small hole (51) that is provided in the valve body to allow the primary flow path of and the back pressure chamber to communicate with each other, and a pin (6) that has a straight portion inserted into the small hole to clean the small hole by relative motions of the small hole and the straight portion. A flow head (34) may be annular and include one or more notches along a perimeter and be configured to engage with an inner peripheral surface of an upper end portion of an inner barrel of the valve device.
