A valve cartridge assembly includes a rod member and a wall member, which defines a channel, which extends through the valve cartridge assembly and surrounds at least a portion of the rod member. A first portion of the channel has a first width dimension which is greater than a second width dimension of the rod member. A first end wall of wall member and the rod member define an inlet opening to first portion of channel. A seal member secured to the rod member, wherein the seal member has a third width dimension greater than a fourth width dimension of the inlet opening and with rod member and the seal member in a first position, seal member is positioned abutting against first end wall closing inlet opening and in a second position, seal member is positioned spaced apart from first end wall which places inlet opening in an open position.

The present disclosure provides an atomization device including a liquid storage cavity, a liquid injection opening, and an injection structure; the injection structure includes an injection tube and a sealing member; the injection tube runs through the liquid injection opening and extends into the liquid storage cavity, and a liquid inlet is formed in a side wall of the injection tube; the sealing member is arranged on one end of the injection tube in the liquid storage cavity; the sealing member is sealed from an inner wall of the liquid storage cavity, and separates the liquid inlet from the liquid storage cavity. When the injection tube is pushed into the liquid storage cavity, the liquid inlet moves into the liquid injection opening to communicate with the liquid storage cavity. When the injection tube is not pushed, the injection tube separates the liquid inlet from the liquid storage cavity.

A flow control apparatus for use with a fluid valve includes a plug having a first portion slidably coupled to a second portion. The first and second portions include opposing bleed ports. The second portion contacts a seat of the fluid valve to close the fluid valve. The apparatus further includes a cavity formed in an outer circumferential surface of the plug by the first and second portions. An axial dimension of the cavity decreases when the first portion slides toward the second portion. The decrease radially outwardly displaces a seal disposed in the cavity. The seal has a curved outer surface configured to engage an inner circumferential wall of a cage of the fluid valve in response to the second portion contacting the seat. The apparatus further includes a pin disposed in the opposing bleed ports to align the first and second portions relative to a common longitudinal axis.

A valve component includes a valve housing having a passage extending along a longitudinal axis; a valve component mountable on the valve housing; a seal to circumferentially seal between the valve housing and the valve component; and a contact abutment to be disposed in the axial direction between the seal and valve housing, and which is configured to be movable in a pre-assembled state relative to the valve housing and the valve component. In an assembled state, the seal can be inserted into an annular-groove-shaped seal receptacle limited by the valve component, valve housing, and contact abutment. The valve housing, valve component, and contact abutment can be matched to each other such that the seal receptacle is reduced when the valve component is mounted on the valve housing, the contact abutment being supported on the valve housing. The contact abutment can undergo a relative movement relative to the valve component.

A valve includes an inlet and an outlet, a body including a first seat and a second seat, wherein the first seat and second seat are spaced apart from each other at a predetermined distance, a cavity in the body, a piston positioned in the cavity, wherein the piston rests against the first seat and the second seat when in the closed position, and a pilot ball adjacent the piston.

A cool water discharging method and a switch valve includes a valve body and a valve spool. The valve body is disposed with a thermosensitive module, an inlet passage, a first outlet passage, and a second outlet passage. The valve body has a cool water discharging passage connected to the inlet passage, a discharging hole connecting the first outlet passage and the cool water discharging passage and an air suction hole connecting the second outlet passage and the cool water discharging passage. When discharging cool water, water flows to the cool water discharging passage rapidly, the air in the second outlet passage is absorbed to the cool water discharging passage. The residual cool water in the second outlet passage is absorbed to the cool water discharging passage through the air suction hole and discharged out with the residual cool water in the first outlet passage.

A switching valve for discharging cold water includes: an operating member, a first switching member, and a water outlet switching member. The switching valve for discharging cold water has a cold water discharging passage and a head water outflow passage. When the operating member is in the initial position, the switching valve for discharging cold water is in the first position, the joint between the head water outflow passage and the water inlet end is sealed, the cold water discharging passage opens; when the operating member switches to the shower position, the first switching member is moved by the operating member to the second position, a second joint between the cold water discharging passage and the water inlet end is sealed, and the head water outflow passage opens, engaging the operating member with the water outlet switching member. The operating member drives the water outlet switching member to open one or both of the first and second water outlet passages.

An inlet valve containing a housing with an entry and an exit and an internal part which together with an external part delimits a flow channel between entry and exit, whereby this flow channel is closable by a valve. The valve includes a piston and a valve member. The piston slides in the housing and is connected with the exit and the valve member is formed by a valve shaft piston which slides in the piston such that in rest mode the valve member is pushed by the piston against valve seat. Between the valve shaft piston and the piston a chamber is enclosed which comes into fluid connection with the pressure vessel and has a blow-off exit forming a fluid connection between the chamber and the entry, whereby the valve shaft piston contains a bypass channel connected with the chamber and the sidewall of the valve shaft piston.

A supplying apparatus of granular material including a storage container storing granular material and a supplying portion having a columnar valve body sliding along an opening direction of a guide hole provided for the storage container. The supplying portion supplies granular material to a supply destination; the valve body includes a material supplying passage penetrating the valve body so as to provide an inlet and an outlet on a side circumferential face and includes a closing portion closing the guide hole when the valve body is at a closed position, the closing portion being provided in the guide hole; and the material supplying passage slants in such a manner that the inlet opens in the storage container and the outlet opens outside the storage container when the valve body is at a supply position supplying granular material.

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.
