Abstract
A multi-way valve includes an upper valve body, a lower valve body and a rotary valve core. The upper valve body and the lower valve body are provided respectively with an upper mounting hole and a lower mounting hole. The rotary valve core is provided passing through the upper mounting hole and the lower mounting hole, respectively. The rotary valve core is formed with a first stepped surface facing toward the upper valve body, and an adjusting nut, which is located below the rotary valve core, is provided in the lower mounting hole. The rotary valve core is moved up and down axially by adjusting the adjusting nut such that an axial clearance between the first stepped surface and the upper valve body is adjusted, so the rotary valve core may flexibly rotate at different temperatures to prevent the multi-way valve from being stuck.
