    摘要: Agate valve (10) includes a valve base (20), a first piston unit disposed in the valve base (20) and driven by a fluid to move the valve door between a first position (P1) where the valve port (212) is opened and a second position (P2) where the valve port (212) is covered, a second piston unit disposed in the valve base (20) and driven by the fluid to move the valve door between the second position (P2) and a third position (P3) where the valve port (212) is sealed, and a valve door fitted to a valve port (212) of the valve base (20). At least one flow channel switch is disposed in the valve base (20). When the flow channel switch is turned on, the fluid is allowed to pass through, such that the second piston unit drives accurately the valve door to seal the valve port (212), thereby achieving purposes of enhancing accuracy in operation and ensuing airproof performance.

    摘要: A valve arrangement for inflating an inflatable device includes a valve body (202) comprising an inlet (204), an outlet (206), a main fluid channel (208), a first ball detent (218), and a second ball detent (220). A lifter (230) and a sleeve (210) are located in the main fluid channel. A locking ball (216) is disposed at least partially within a locking ball aperture (214) disposed in the sleeve. A piston (226) is coupled to the lifter and fluidly coupled to a command pressure cavity (224) of the valve body. A spring (228) biases the lifter toward a ball locking position whereby the lifter urges the locking ball at least partially into the first ball detent. A valve operation initiator (250) controls a flow of pressurized gas into the command pressure cavity to urge the lifter to a ball releasing position to free the sleeve, as to the locking ball, to translate to an open position to fluidly couple the inlet with the outlet.
