A valve body and a control valve including such a valve body, the valve body including an inlet, an outlet, and a valve port defined therebetween. The valve body also includes a plurality of discrete flow channels that extend between the inlet and the valve port to distribute fluid flow to the valve port in a manner that equalizes the velocity of fluid at the perimeter of the valve port. The plurality of discrete flow channels includes (i) one or more first flow channels arranged to direct a first amount of the fluid flow to a front portion of the valve port, (ii) one or more second flow channels arranged to direct a second amount of the fluid flow to a rear portion of the valve port, and (iii) one or more third flow channels arranged to direct a third amount of the fluid flow to one or both side portions of the valve port.

Equipment for fluid transfer includes a valve, a frame that defines a housing for the valve and an upstream passage for the fluid that leads into the housing and is fluidically connectable to a fluid source, the valve being able to move between a non-inserted position and an inserted position in which the valve is situated at least partially in the housing, a module that defines a downstream passage for the fluid that fluidically connectable to the reservoir, the module being able to move between an open position, allowing the insertion of the valve, and a closed position in which the module is fixed to the frame, and two seals that are respectively compressed substantially between the valve and the frame and between the valve and the module when the valve is in the inserted position and the module is in the closed position.

An assembly includes a valve housing and a valve element such as a poppet valve. The valve housing includes a tubular duct and an annular valve seat disposed within the tubular duct. A first flowpath includes an inner bore of the annular valve seat. A second flowpath includes an aperture formed between the annular valve seat and the tubular duct. The poppet valve is configured to engage the annular valve seat and substantially close the first flowpath when the poppet valve is in a first position. The poppet valve is further configured to disengage the annular valve seat and at least partially open the first flowpath when the poppet valve is in a second position.

The invention relates to a valve, in particular to a quantitative water adjusting valve which comprises a valve body and a sealing pressure column, a control mechanism, a sealing element, a quantitative orifice plate and an end cover. The device disclosed by the invention is convenient to detach, so that the internal structure of the device is convenient to maintain; the valve can be quickly opened, and the valve can be slowly opened and closed through threads; under the condition that the water pressure is certain, the flow of water can be conveniently and quantitatively controlled.

An on-off valve of the present invention includes a valve box which includes an inlet flow path of steam and an outlet flow path which communicates with the inlet flow path through a communication bole, a stop valve body which opens or closes the communication hole, and a stop valve support portion, in which the outlet flow path extends in a direction intersecting the opening direction of the communication hole toward a downstream side in a flow direction of the steam, and a minimum wall thickness of the valve box is smaller than a minimum wall thickness of the valve box.

An equalization shutoff valve includes a housing having an outward extending flange around an open end of the housing, retaining clips attached to the flange configured to engage a battery pack compartment, and piston guides disposed inside the housing; a piston having guide notches engaging the piston guides, and a first flow port; a spring disposed between the housing and the piston to urge the piston in a direction away from a closed end of the housing; and a locking tab cover attached to the housing with the piston inside the housing, and having a second flow port and locking tabs with clip ports. The housing is attached to the battery pack compartment through the retaining clips so that air flows from inside the battery pack compartment, and when pressure inside the housing increases, increased pressure pushes the spring and the piston to allow air to exit from the housing.

A heat exchanger valve includes a housing (2) having an inlet, an outlet a valve seat (5) on a valve seat member (24) between inlet and outlet, a valve element cooperating with the valve seat (5) and having a valve element axis, and presetting mechanism having a bushing (9) which is rotatable around the valve element axis and has an opening arrangement cooperating with a counter passage in the housing (2), wherein in the region of the opening arrangement the bushing (9) has a conical form cooperating with a conical counter face (13) and a distance is provided between the bushing (9) and the valve seat member (24). Such a heat exchanger valve should allow a precise pre-setting over a large range. To this end the bushing (9) has at least two notches (14) in an edge (10) facing the valve element member (24), each of the notches (14) forming an opening (25).

A flow rate control valve is configured to adjust a flow rate of blow-by gas drawn into an intake passage from a crankcase of an internal combustion engine that uses hydrogen as fuel. The flow rate control valve includes a flow rate adjuster having a valve member. The flow rate adjuster has a cross-sectional flow area in a section through which the blow-by gas passes. The cross-sectional flow area is changed in accordance with movement of the valve member. The flow rate control valve is configured such that the cross-sectional flow area is maximized when a load on the internal combustion engine is less than or equal to that in an idling operation state.

An expansion switch valve includes a valve body, where an inlet, an outlet, and an internal passage in communication between the inlet and the outlet are formed on the valve body, a first valve plug and a second valve plug that are coaxial and are spaced apart from each other are mounted on the internal passage, the first valve plug makes the inlet and the outlet in direct communication or out of communication, and the second valve plug makes the inlet and the outlet in communication through a throttle hole or out of communication. In this way, an opening/closure control function or a throttle expansion control function can be implemented on a refrigerant by integrally mounting the first valve plug and the second valve plug that are coaxial and are spaced apart from each other on the internal passage of the same valve body. A structure is simple, and production and installation are easy.
