A valve closing member for cooperating with a valve seat, comprising: a body a front circular face forming a central protrusion along a longitudinal axis of the body; a seal forming a ring fitted on the front circular face and around the central protrusion; and a retainer forming a ring surrounding the seal and attached to the body for retaining the seal on the body; wherein the seal shows a radially inner surface contacting a radially outer surface of the central protrusion, the radially inner surface and radially outer surface being both cylindrical, the radially outer surface showing at least one circular groove into which the seal is radially pressed by the retainer.

A safety release bleeder valve serving as a plug includes a barrel having an exterior surface and an interior throughbore surface for matingly receiving a plug having a top end with exterior threads and an interior socket for receiving a driver tool for moving the plug between an open venting state and a closed non-venting state.

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.

One embodiment is a device comprising a first and second section of a housing connected by a connection region that uses a plurality of connection elements, an inlet connected to the first or the second section, an outlet connected to the first or the second section where a gas can exit the housing, and a valve connected to the outlet, the valve capable of withstanding a first pressure in the housing.

The present invention provides a leak-proof fluid dispensing system with pressure sensor and pre-set and fixed dispensing pressure reducing regulator including a gas cylinder having a containing space, a pressure sensor and a dispensing control valve. The dispensing control valve having internal channels that communicate with an inlet port, an outlet port, a bottle port, a pressure sensor and a joint portion so that the bottle port is communicated with the containing cylinder space.

The leak-proof fluid dispensing system includes an inlet valve connected to the inlet port and the internal channel, an outlet valve connected to the outlet port and the internal channel, a pressure dispensing reducing regulator connected to the outlet port and the bottle port through the internal channel and preset and fixed with an opening pressure value. When the actual pressure at the outlet end of the pressure dispensing regulator is lower than or equal to the opening pressure value, then the pressure dispensing regulator is being opened. A pressure sensor disposed on the dispensing body and having pressure sensitively is connected to the internal channel and the bottle port.

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.

A gas valve is adapted for controlling the flow of a medical gas for oxygen therapy in case of spontaneous breathing. The gas valve comprises a connection component for connecting the gas valve to an external supply; and a regulating system configured for selecting and supplying a pulsating flow of medical gas or a continuous flow of medical gas, in which the regulating system comprises a first sub-regulating system for supplying a pulsating flow and a second sub-regulating system for supplying a continuous flow.

A valve for pressurized fluid having a body housing a fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit having a collection of valve shutter(s) having at least one shutoff valve shutter allowing the circuit to be closed or opened, the valve having a member for manually controlling the collection of valve shutter(s), the control member being mounted to allow the body to move between a rest position in which the collection of valve shutter(s) is in a position in which the circuit is closed and an active position in which the control member actuates the collection of valve shutter(s) into a position in which the circuit is open with a first bore section

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 valve assembly for a dispenser. The valve assembly includes a valve body that extends about a longitudinal axis and defines an outer surface and an inner passageway. The valve body includes a first valve body surface and a second valve body surface opposite the first valve body surface. A valve stem extends through the inner passageway and includes an outer stem surface, an inner stem surface opposite the outer stem surface, and a first orifice extending from the outer stem surface to the inner stem surface. A resilient member is disposed on at least a portion of the first valve body surface. The resilient member is made from a resilient polymeric material and has a non-linear compression profile.
