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.

Disclosed is steering drive device for a pressing-controlled valve core, the steering drive device including a fixed top frame, a lifting drive rod, a vertical guide column, a lifting receiving seat, a fork-shaped swinging member, and a steering linkage. The steering linkage has an end that swings laterally when being moved, and the laterally swinging end is provided with a through hole for the fork-shaped swinging member to drive the swing arm, and cause the horizontal post to axially slide. The vertical cross-section of the through hole is rectangular, and the drive horizontal column has a range of up and down movement space in it, so that, when the drive swing arm generates lateral displacement due to vertical swing, it will pull the steering linkage along a circular path laterally moving, and at the same time drives the valve to rotate the actuating seat and cause it rotate laterally.

A dustproof gate valve includes a housing having a first panel, a second panel, and a valve port on each of the first and second panels, a slide including a body and a valve member and drivable to move between a first position and a second position, the slide closing the valve port of the first panel when at the first position, a driver mounted in the housing, a swing arm having one end thereof connected to the driver for moving the slide, and a dust pipe mounted in said body. When the slide is at the second position, the dust pipe is disposed between the valve port of the first panel and the valve port of the second panel, and the pipe wall of the dust pipe separates the valve ports of the first and second panels from the accommodation space.

A flow regulation device for liquid having a body with an inlet opening, an outlet opening, and a cavity between the two openings. An actuating means is disposed in the cavity for stopping and starting the flow of liquid through said device. The actuating means is configured to be moved in a first direction to start the flow of liquid through said device and in the first direction to stop the flow of liquid through said device. The actuating may comprise an upper button and a lower cam.

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 proportional solenoid, capable of linear motion, includes an electromagnetic valve device including a solenoid assembly having a mobile core, a push rod connecting the solenoid mobile core to a valve plunger, and a device operable to apply a controlled friction force to hold the mobile core in an intermediate position. The friction force applied by the friction device is greater than the motive forces generated by the solenoid.

A dustproof gate valve includes a housing having a first panel, a second panel, and a valve port on each of the first and second panels, a slide including a body and a valve member and drivable to move between a first position and a second position, the slide closing the valve port of the first panel when at the first position, a driver mounted in the housing, a swing arm having one end thereof connected to the driver for moving the slide, and a dust pipe mounted in said body. When the slide is at the second position, the dust pipe is disposed between the valve port of the first panel and the valve port of the second panel, and the pipe wall of the dust pipe separates the valve ports of the first and second panels from the accommodation space.

A vent shut-off assembly configured to manage venting on a fuel tank configured to deliver fuel to an internal combustion engine includes a first liquid vapor discriminator (LVD), a main housing, a first poppet valve assembly, a pump and an actuator assembly. The first LVD is disposed in the fuel tank. The main housing selectively vents to a carbon canister. The first poppet valve assembly has a first poppet valve arranged in the main housing. The pump selectively pumps liquid fuel from the main housing. The actuator assembly is at least partially housed in the main housing and includes a cam assembly having a cam shaft that includes a first cam and a second cam. The first cam has a profile that one of opens and closes the first poppet valve fluidly coupled to the first LVD.

A control valve assembly is provided for a fluid treatment system, including a housing having a top portion and a bottom portion secured to the top portion, the housing including an inlet and an outlet. At least two modular chambers are secured in the housing. A first chamber is configured to receive fluid from the inlet and a second chamber is configured to provide fluid to the outlet. A piston is also provided which includes a shaft with a plurality of sealing rings. The piston extends through the housing and through the first chamber and the second chamber. The piston is configured to reciprocate in an axial direction to control the flow of fluid in the control valve assembly.

Disclosed is a water softener valve and a water softener, the water softener valve includes a valve body, the valve body includes a valve cavity, and an inlet passage, an outlet passage, and a waste water passage all communicated with the valve cavity, the valve cavity, the inlet passage, the outlet passage, and the waste water passage all extend towards a first direction, the inlet passage, the outlet passage, and the waste water passage are all located at a periphery of the valve cavity, and adjacent to the valve cavity; ends of the inlet passage, the outlet passage, and the waste water passage which are all located at a same end of the valve body towards the first direction respectively form an inlet, an outlet, and a waste water port.
