A water faucet includes a first pipe, a housing and a first sealing ring. The first pipe includes a first sidewall, a second sidewall, a third sidewall and a first sliding portion. The first pipe includes a first accommodate space and an inlet. The housing includes a top wall, a second pipe and a second sliding portion corresponding to the first sliding portion. The second pipe includes a fourth sidewall connected with the top wall to form a second accommodate space and an outlet. When the first sliding portion slides to a first position, the first sealing ring is located between the fourth and the second sidewall to prevent water flowing between the first pipe and the housing. When the first sliding portion slides to a second position, water from the inlet can flow to the outlet via the first accommodate space, the though hole and the second accommodate space.

A fluid control valve having a body, a seat ring, a valve cage adjacent the seat ring, a first valve plug assembly positioned within the valve cage, and a second valve plug assembly positioned within an axial bore of the first valve plug assembly. The first valve plug assembly has radial apertures in fluid communication with the axial bore and a first valve plug including the axial bore and a throttling port in fluid communication with the axial bore. The first valve plug assembly is movable between a closed position, in engagement with the seat ring, and an open position, spaced apart from the seat ring. The second valve plug assembly has a second valve plug that is movable between a closed position, in engagement with the first valve plug, and an open position, spaced apart from the first valve plug.

A guide frame for a four-way reversing valve is provided. The guide frame includes a frame body. Both ends of the frame body are provided with a connecting portion, respectively. The connecting portion includes a first bending member and a second bending member, and the directions of bending of the first bending member and of the second bending member are opposite. The connecting portion is provided with a reinforcing member. The reinforcing member includes a first reinforcing plate and a second reinforcing plate. The first reinforcing plate is connected to the outer side of the first bending member by welding, and the second reinforcing plate is connected to the outer side of the second bending member by welding. Optionally, the first reinforcing plate is connected to the inner side of the first bending member by welding and the second reinforcing plate is connected to the inner side of the second bending member by welding. The connection strength of the connecting portion is increased, such that the guide frame is less likely to deform or break.

A method and apparatus for selective connection of a first fluid communication region to a further fluid communication region at a subsea location and a flexible pipe are disclosed. The apparatus comprises a valve body that includes a primary passageway extending from a first port of the valve body, and connectable to a first fluid communication region, to a further port of the valve body, connectable to a further fluid communication region, the valve body comprising a channel intersecting the primary passageway and extending between an open channel end and a closed channel end; at least one slidable member comprising a slidable body locatable in the channel and comprising a slidable member fluid passage extending through or around the slidable body; and at least one biasing element locatable proximate to at least one of the open channel end or closed channel end, for biasing the slidable body towards the open channel end; wherein the slidable member is slidable along a longitudinal axis of the channel responsive to a local environmental pressure provided at the open channel end.

A valve having a metal insert with a fluid passage formed in the metal insert. A composite valve body is disposed at least partially around the metal insert and having at least one port in fluid communication with the fluid passage with the metal insert. A valve member is partially disposed in the metal insert and operable to control the fluid flow through the fluid passage of the metal insert and parts of the valve body.

A metering valve has a main inlet port and a spool movable, and a housing outlet port in a housing. The spool has a metering inlet orifice selectively aligned with the main inlet port, and a metering outlet orifice selectively aligned with the main outlet port. The main inlet port communicates with the metering inlet orifice, and the outlet port communicates with the metering outlet orifice to each provide a metering orifice. The main outlet port communicates downstream to a minimum pressure valve. The minimum pressure valve has a piston biased to a closed position by a spring force, and a line downstream of the main outlet port acting against a face of the piston in opposition to the spring force to ensure a minimum pressure moving downstream past the piston to a use. A fuel system is also disclosed.

The hydraulic pressure relief depressurization valve assembly for quick coupling which is object of the present invention comprises a depressurization valve assembly (100) and (200) that can be assembled in any quick coupling that has a directional body (10) and (60), generally fixed to a manifold with access to the tank (20), an intermediate sleeve (30) and (80) and a port (40) for connection to the hydraulic system, inside which is a relief valve (50) and (90), that moves axially, provided with directional holes that make it possible to relieve the pressure during the connection and disconnection action (during the manual push and pull movement), so as to minimize the pressure forces and facilitate the installation and replacement or changing of hoses on the hydraulic line.

A valve assembly is adjustable in three independent ways allowing it to provide a variable input volume. The valve assembly has a base and an entrance plate. An outer guide, an inner guide and a shaft, each with a passage, are held together and the shaft is rotatable between the guides. The valve is open when the passages of the inner guide plate and shaft are aligned and closed when the passages are not aligned. The shaft RPM determines how many times per minute the valve opens. The open/closed ratio of the valve assembly determines how long the valve is open during each half revolution. The location of the shaft up or down in relationship to the inner guide determines what percentage of possible flow passes through the valve during each half revolution. The valve assembly can be used with either a gas or liquid medium.

There are provided a steam valve and the like capable of preventing breakage of an auxiliary valve element and effectively suppressing the occurrence of a leak of steam in the auxiliary valve element. In the steam valve of an embodiment, the auxiliary valve element is structured to be in an open state in which the valve rod moves in an opening direction to increase a distance between an auxiliary-valve cap and a main valve element, thereby opening an auxiliary-valve steam introduction hole, and to be in a fully-closed state in which the valve rod moves in a closing direction in which the main valve element is closed to bring the auxiliary-valve cap and the main valve element into contact with each other, thereby closing the auxiliary-valve steam introduction holes. A contact position in which the auxiliary-valve cap and the main valve element are brought into contact with each other is located outside in a radial direction of the valve rod from the outer peripheral surface, of the auxiliary-valve tubular part, through which the auxiliary-valve steam introduction holes are formed.

A method and system for determining a position of a linearly translating member. The method may comprise transmitting an excitation into a linearly translating member through one or more couplers from an acoustic device disposed in an outer housing, recording a reflected excitation from the linearly translating member with the acoustic device, and identifying a position of the linearly translating member with respect to the acoustic device. The system may comprise an outer housing, a linearly translating member disposed within the outer housing, an acoustic device disposed in the outer housing and configured to transmit an excitation at various frequencies and various amplitudes and record returned excitation frequencies and amplitudes and time of travel, and an information handling system in communication with the acoustic device.
