the output lever of the actuator acts on the valve flap for driving the valve flap to alternatively bear against the end opening of the valve seat or against the inner opening of the first outlet.
Particularly, the valve body is a cross-shaped right-angle hollow pipeline, the inlet and the second outlet are distributed at two ends in the horizontal direction, and the first outlet and the flange opening are distributed at two ends in the vertical direction.
In particular, the cross-sectional dimension of the valve flap is larger than the end opening of the valve seat and the inner orifice of the first outlet and smaller than the through-hole and the flange opening of the partition.
Particularly, a valve cover is arranged on the flange opening, the actuating mechanism is fixed on the outer side of the valve cover, and an output rod of the actuating mechanism extends into the valve cover and penetrates through the valve seat to be fixedly connected with the valve clack.
Particularly, the valve cover and the flange opening are fixed through bolts, and a sealing gasket is clamped between the valve cover and the flange opening.
Particularly, a sleeve is connected between the actuating mechanism and the valve cover, an output rod of the actuating mechanism penetrates through the sleeve, and a sealing filler is clamped between the sleeve and the output rod and is tightly pressed through the spring pressing plate assembly.
In particular, a seal ring is interposed between the end of the valve seat and the through hole of the partition.
To sum up, the beneficial effects of the utility model are that, compared with the prior art, the tee bend control valve realizes whole and valve body installation and separation with valve clack, disk seat and actuating mechanism as the sub-assembly, and the valve body can remain on the pipeline during maintenance, but valve internals quick replacement need not be maintained on line with the help of specialized tool, the convenience.

fig. 2 is a cross-sectional view of a three-way control valve provided by the embodiment of the present invention.
Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Referring to fig. 1 and 2, the present embodiment provides a three-way control valve, which includes a valve body 1, a valve seat 2, a valve flap 3 and an actuator 4.
The valve body 1 is provided with an inlet 5, a first outlet 6, a second outlet 7 and a flange opening, the inner cavity of the valve body 1 is hollow and is communicated with the openings, a partition is arranged in the inner cavity and between the first outlet 6 and the second outlet 7, a through hole is formed in the partition, and the first outlet 6, the through hole and the flange opening are located on the same axis.
Particularly, in order to reduce the fluid resistance and optimize the whole volume, the valve body 1 is a cross-shaped right-angle hollow pipeline, the inlet 5 and the second outlet 7 are distributed at two ends in the horizontal direction, and the first outlet 6 and the flange opening are distributed at two ends in the vertical direction.
The valve seat 2 is arranged from the flange opening, the end part of the valve seat 2 is in sealing fit with the through hole, and a sealing ring 11 is clamped between the end part of the valve seat 2 and the separated through hole. A flow passage 12 extending from the end surface to the side surface is provided in the valve seat 2, and the flow passage 12 communicates with the second outlet 7.
