摘要： A valve comprises a body that includes a first channel connected to the gas tank and a second channel connected to a circuit, with the first and second channels communicating with a central housing. The valve comprises a closure member movable between a closed position of the first channel and a supply position in which the first and second channels communicate. A third channel is formed in the body and communicates with the central housing The closure member is configured to isolate the third channel from the first and second channels in the closure and supply positions, and to allow communication between the third channel and the first and second channels in a discharge position.

摘要： A dispenser includes a housing, an inverted container disposed in the housing, a outlet nozzle, a pump, a first check valve, and a second check valve. The pump is disposed between the container and the outlet nozzle. The pump includes a pump inlet a pump outlet, and a pump chamber. The pump chamber is movable between an expanded position and a compressed position. The first check valve is disposed between the pump and the outlet nozzle, and the first check valve has a first cracking pressure. The second check valve is disposed between the first check valve and the outlet nozzle, and the second check valve has a second cracking pressure. The second cracking pressure of the second check valve is greater than the first cracking pressure of the first check valve.

摘要： A pressure regulating shut-off valve has a valve member regulating flow of fluid between an inlet and an outlet. The valve includes a pneumatic actuator having a piston having first and second faces that define first and second volumes within a cylinder. The second face has a greater surface area than the first face. The first and second volumes are fluidly connected to the inlet, and an electrically actuated valve controls the flow of fluid along a fluid path to the second volume. The electrically actuated valve closes the fluid path, when power is supplied to the electrically actuated valve, and opens the fluid path, when power is removed from the electrically actuated valve, which causes the pneumatic actuator to act on the valve member to hold the valve member in a fixed position.

摘要： A valve assembly for a dispenser. The valve assembly includes a valve body. The valve body includes a first hoop member, a second hoop member, and a transition portion defined by the joining of the first hoop member and the second hoop member. The first hoop member includes a first hoop outer portion positioned, a first hoop inner portion, a first hoop upper surface, and a first hoop lower surface. The second hoop member includes a second hoop outer portion, a second hoop inner portion, a second hoop upper surface, and a second hoop lower surface. The second hoop inner portion extends about the longitudinal axis defining a passageway. The passageway comprises a first passageway opening, a second passageway opening opposite the first passageway opening, and a passageway surface extending from the first passageway opening to the second passageway opening.

摘要： The present invention provides a leak-proof fluid dispensing system with a pressure sensor and an adjustable dispensing regulator, comprising: a gas cylinder and a pressure dispensing control valve. The dispensing control valve is formed outside the bottle body opening and has an internal channel that communicates with an inlet port, an outlet port, a bottle port, and the joint portion. The internal of the dispensing body includes an inlet valve, an outlet valve, a pressure dispensing regulator, a filter, and a pressure sensor. The pressure at the outlet end of pressure dispensing regulator is lower than or equal to a preset opening pressure value, the fluid is allowed to flow out. With the implementation of the present invention, it may prevent accidental leakage of fluid in the gas cylinder and dynamically monitor the flow gas capacity in the gas cylinder.

摘要： A compressed gas storage system that includes a pressure vessel. The pressure vessel includes a first vessel portion and a second vessel portion in fluid communication with the first vessel portion. The pressure vessel includes a third vessel portion in fluid communication with the second vessel portion. The compressed gas storage system includes a first valve positioned between the first vessel portion and the second vessel portion and a second valve positioned between the second vessel portion and the third vessel portion. The first valve allows and impedes fluid flow between the first and the second vessel portions. The second valve allows and impedes fluid flow between the second and the third vessel portions.

摘要： A blood pressure measurement system is provided that includes an inflatable cuff, a valve assembly and chamber assembly. The chamber assembly can house a gas canister for providing gas to the inflatable cuff. The valve assembly can include a valve having a high pressure cavity, a low pressure cavity, and a channel providing a gas pathway between the high pressure cavity and the low pressure cavity. The valve assembly can further include a channel cover and spring in the high pressure cavity. The spring can exert a force on the channel cover to create a seal between the high pressure cavity and the channel. The valve assembly can further include a rod extending through the channel and exerting a force on the channel cover to create a gas pathway between the high pressure cavity and the channel.
