An outlet pipe 6 is arranged outside the outlet 5.
The outlet pipe 6 is externally provided with a connecting flange 7.
The longitudinal section of the valve core flow passage 8 is circular, and the diameter of the longitudinal section is directly matched with the outlet 5.
The valve core flow passage 8 is curved in an arc shape.
Example 2
Based on embodiment 1, the rotary handle 3 can be connected with a motor driving device for realizing automatic control, so as to realize automatic control of the valve.
The utility model discloses a working process (with embodiment 1 as the basis):
firstly, a pipeline switching valve connects a device I9 and a device II 10 with a main pipeline in a mode as shown in fig. 3 or 4, a main pipeline inlet 11 is connected with a main inlet 5a, a main pipeline outlet 12 is connected with a main outlet 5d, an inlet and an outlet of the device I9 are connected with a device I inlet 5b and a device I outlet 5e on a valve body 1, and an inlet and an outlet of the device II 10 are connected with a device II inlet 5f and a device II outlet 5c on the valve body 1.
