PLUG VALVE AND HOUSEHOLD APPLIANCE Russian patent published in 2023 - IPC F16K5/02 F16K5/08 F24C3/12 

FIELD: valves.

SUBSTANCE: plug valve includes a body, a valve seat mounted on the body and having a hollow mounting column provided on it. Valve stem extending into the mounting column. The valve stem has one starting groove formed on its outer peripheral surface. The trigger groove includes an upper trigger surface and a lower trigger surface for actuating two switches. The different states of the two switches can be combined with each other to meet more requirements. The valve stem also has a retaining block protruding from below. The valve seat has a regulating surface and a locking groove made in its lower part. The stop block is located in the stop block to limit the rotation of the valve stem, when the valve stem is pressed, the stop block comes out of the stop groove to remove the restriction on the rotation of the valve stem, when the valve stem rotates, the stop block is located on the control surface, and when the valve stem is released when pressed, the stop block is on the control surface, or the stop block is in the locking groove.

EFFECT: providing one starting groove on the valve stem to form an appropriate starting structure, the processing requirements of the valve stem can be simplified, resulting in higher and more reliable production efficiency.
