MULTI-WAY VALVE Russian patent published in 2018 - IPC F16K11/72 

FIELD: valves.

SUBSTANCE: multi-way valve is provided, comprising upper valve body (1), lower valve body (2), and rotatable valve core (3). Upper valve body (1) and lower valve body (2) are respectively provided with an upper mounting hole and a lower mounting hole. Rotatable valve core (3) is designed so that it passes through the upper mounting hole and the lower mounting hole, respectively. Rotary valve core (3) is formed with first step surface (31) facing upper valve body (1) and adjusting nut (4) is located in the lower mounting hole, which is located below rotatable valve core (3). Rotatable valve core (3) moves up and down by regulation of adjusting nut (4) so as to adjust the axial clearance between first step surface (31) and upper valve body (1), so that rotatable core (3) of the valve can be rotated to adapt to different temperatures to prevent the multi-way valve from being trailed.

EFFECT: multiway valve is proposed.
