A flow regulating switch valve includes a valve core that includes a switch assembly configured to drive a diaphragm assembly to open or close a water outlet, and also includes a flow regulating assembly that comprises a rotating ring, a sliding block, and a magnet. A control key is configured to control the switch assembly. The rotating ring is connected to the control key and includes an inclined plane that transitions from high to low and is configured to drive the sliding block to slide up and down such that the sliding block drives the magnet to move up and down. The magnet is configured to control the diaphragm assembly to regulate a size of the water outlet.

A digital water timer may include a main body, a water valve, a locating base, a driving base, and a timer. The main body has a water inlet and a water outlet, and a valve tube protrudes from a lateral side of the main body. The water valve connected to the main body is controlled by the timer to achieve on/off operation of channels inside the main body. The locating base is secured on the main body, and the driving base is adapted to have rotation relative to the locating base and be secured at a specific position after rotated. The timer installed in the driving base comprises a display panel and an operation interface which are exposed externally for operation. The driving base with the timer is rotated relative to the locating base, and the display panel is adjusted as needed to provide an optimal view for operation.

A valve arrangement comprising a valve housing, a valve inlet, a valve outlet and a diaphragm assembly for controlling a fluid flow through the valve housing from the valve inlet to the valve outlet, the diaphragm assembly comprising a diaphragm and a diaphragm plate at least partially covering the diaphragm, the diaphragm comprising one or more equalization holes passing through the diaphragm and the diaphragm plate comprising one or more equalization openings passing through the diaphragm plate, the equalization holes being aligned with the equalization openings. The diaphragm assembly comprises an engagement zone engaging the diaphragm in order to rotationally fix the diaphragm and the diaphragm plate with respect to each other so that the equalization holes will keep aligned with the equalization openings to ensure proper function of the valve arrangement at all times.

The present disclosure provides a flow control valve for controlling the flow of a cleaning media, such as controlling the flow of cleaning media to a nozzle positioned to distribute the cleaning media to a vehicle surface. The flow control valve includes a plunger and a flexible diaphragm which operate to open and close the a fluid passage through the valve. Vehicles and systems incorporating a flow control valve are also provided.

A digital water timer may include a main body, a water valve, a locating base, a driving base, and a timer. The main body has a water inlet and a water outlet, and a valve tube protrudes from a lateral side of the main body. The water valve connected to the main body is controlled by the timer to achieve on/off operation of channels inside the main body. The locating base is secured on the main body, and the driving base is adapted to have rotation relative to the locating base and be secured at a specific position after rotated. The timer installed in the driving base comprises a display panel and an operation interface which are exposed externally for operation. The driving base with the timer is rotated relative to the locating base, and the display panel is adjusted as needed to provide an optimal view for operation.

A magnetically-operable shutter assembly comprises a fixed core and a movable core which can be configured between a contact condition and a condition of the utmost mutual distance and further comprises an encapsulation body capable of simultaneously containing the fixed core and the movable core; the encapsulation body can be installed within a body of a complex functional assembly which is configurable at least in a hindrance configuration for a fluid flow and in an admittance configuration for said fluid flow through the complex functional assembly itself.

A solenoid valve for irrigation system may include a gardening tube, a rubber valve piece, a cover, and a valve column. The gardening tube has a water inlet channel and a water outlet channel which are communicated, and a valve tube vertically extends from the gardening tube. A vertical first connecting tube is formed inside the valve tube. The valve piece is movable in the valve tube to abut against the first connecting tube. The cover comprises a second connecting tube vertically protruding from the cover, and the second connecting tube has a valve chamber formed at a first end thereof which is communicated with the valve tube. The valve column arranged in the valve chamber of the second connecting tube has a tapered end faced to the valve piece.

Provided is a pilot solenoid valve capable of bringing the strokes of a plunger to a necessary minimum and capable of achieving solenoid valve miniaturization and power saving. A pilot solenoid valve is provided with a diaphragm section, a primary side section, a secondary side section, a main valve, a back pressure chamber, a primary side auxiliary flow path, a secondary side auxiliary flow path, an auxiliary valve, and an auxiliary valve drive unit, wherein the secondary side auxiliary flow path is not formed in the main valve but rather is formed in the area around the main valve so as to bypass the main valve.

A method of controlling actuation of a flush apparatus includes the steps of configuring a control module to actuate the flush apparatus for completing a flushing cycle periodically; and after a given unused time period of the flush apparatus, enabling the control module to enter into a sleep mode to stop an actuation of the flush apparatus. Therefore, during the rush hours, the control module is configured to actuate the flush apparatus frequently and during the off rush hours, the control module is configured to actuate the flush apparatus seldom.

The present invention is a flow-rate adjustable valve for adjusting a flow rate of liquid flowing through a flow path. The flow-rate adjustable valve includes: a main valve body; a back pressure chamber; an inlet hole; an outlet hole; a pilot valve body for opening and closing an end of the outlet hole on a side of the back pressure chamber; an elongated member holding the pilot valve body; and a lifter rotatable and also movable in the axial direction of the elongated member by the rotation of the rotatable member. The lifter and the elongated member are integrally movable in the axial direction. The elongated member is connected to the lifter under a condition in which the elongated member is biased to the lifter in a one-way direction of the axial direction by a biasing-connecting member.
