A detachable coupling device with automatic closure for the transport of fluid, including two fluid transport pipes extending in a longitudinal direction and each having, at one connection end, a valve mechanism, the device also including an external tube disposed around each transport pipe and, in the coupled position, the two connection ends are configured to be relatively longitudinally displaceable between a first configuration, in which the valve mechanisms are dosed, and a second configuration, in which the valve mechanisms are open, the transition from the first configuration to the second configuration being realized by a relative longitudinal movement of the two valve mechanisms close to one another

A water supply device (10) and a tube connector structure (2) thereof, which are used for an electronic device (100) having a water inlet (101) and a water outlet (102), are disclosed. The tube connector structure (2) includes a connecting plate (21) and two tube connector plugs (22) passing through and fixed to the connecting plate (21). One of the tube connector plugs (22) is connected with the water inlet (101), and the other one of the tube connector plugs (22) is connected with the water outlet (102). Therefore, advantages of rapid connection and disconnection between the water supply device (10) and the tube connector structure (2) and saving time and labor in assembling may be accomplished.

A charge valve assembly for an air conditioning system includes a valve housing having a first end, a second end, and an inner surface defining a cavity. A valve core assembly is received in the cavity of the valve housing through the second end of the valve housing. The valve core assembly has a first end, a second end, a flow channel extending from the first end of the valve core assembly to the second end of the valve core assembly, an inner sealing surface, and a pin slideably received in the flow channel between an open position and a closed position. The pin has a primary seal selectively engaging the inner sealing surface of the valve core assembly and closing the flow channel at the second end of the valve core assembly when in the closed position. The pin biases towards the first end of the valve housing.

An adjustable connector for refrigerant pipe includes a body, a valve pin is inserted into the body, and the body includes a quick-release assembly and a driving member respectively disposed on a mounting part and an installation part thereof. When the driving member is operated to suppress the pressed end of the valve pin to move the pushing end close to the pocket, the valve spout is opened to pass the refrigerant. Besides, when the driving member is operated to not suppress the pressed end by jumping off itself quickly, the pushing end is moved away from the pocket, so that the valve spout is closed to block the refrigerant.

A fluid coupling includes a body, a poppet valve assembly, a handle shaft assembly, and a retention member. The body has a fluid conduit, a through-hole extending through a sidewall, and one or more openings that extend between an external surface of the body and an interior of the through hole. The poppet valve assembly is disposed within the fluid conduit and is selectively movable between an open position and a closed position. The handle shaft assembly extends through the through-hole and into the fluid conduit and is interconnected with the poppet valve assembly such that the handle shaft assembly can be actuated to move the poppet valve assembly between the open position and the closed position. The retention member is insertable through the one or more openings and into the through-hole to interact with the handle shaft assembly to selectively hold the handle shaft assembly in the body.

A connector assembly has a main body, a valve, a spring, a quick connecting device, and a seal. The valve is moveably mounted in the main body and has an adaptor, a valve body, and a sealing assembly. The valve body is spaced from the adaptor and has a closed end away from the adaptor, an open end, and multiple through holes radially defined in the valve body. The seal is clamped between the valve body and the adaptor to connect the valve body with the adaptor and has a tubular sleeve and a clamped flange. The tubular sleeve has an end. The clamped flange is radially formed around and protrudes from the end of the sleeve and clamped between the open end of the valve body and the adaptor.
