Abstract
The disclosure provides a control valve which includes a valve body and a valve gate. The valve gate is movably located inside the inner space. The control valve has a lower flow rate limit which is greater than zero. That is, the lower flow rate limit has no necessary to be zero, thus it is acceptable to have a cylindrical valve gate but not a spherical valve gate, and a diameter of the cylindrical valve gate is be smaller than a caliber of an opening of the valve body. Therefore, the valve gate can be directly installed into the valve body via the opening, which allows the valve body to be made of a single piece so as to simplify the processes of manufacturing and assembly.

A control valve, comprising:
- a valve body, having an inner space, at least one fluid inlet and at least one fluid outlet, the at least one fluid inlet and the at least one fluid outlet corresponding to the inner space, the valve body having an inner wall surrounding the inner space;
- and
- a valve gate, having an external wall and at least one main channel, the valve gate movably located inside the inner space, the external wall and the inner wall forming a bypass channel, the main channel penetrating through the external wall, and the main channel having at least one inlet end and at least one outlet end which respectively correspond to the at least one fluid inlet and the at least one fluid outlet;
- wherein, the valve gate is movable with respect to the valve body and pivotable between a closed position and an opened position;
- when the valve gate is in the closed position, the at least one inlet end and the at least one outlet end of the main channel are blocked by the valve body, such that the fluid inlet is connected to the fluid outlet only via the bypass channel;
- when the valve gate is in the opened position, the at least one inlet end and the at least one outlet end of the main channel are respectively connected to the at least one fluid inlet and the at least one fluid outlet, such that the fluid inlet is connected to the fluid outlet via the main channel and the bypass channel.
