Claims

[Scope of utility model registration request]

A first port, a second port, and a third port are provided in the valve box,
The flow path between the ports is switched by opening and closing a first valve seat and a second valve seat provided at opposite positions of a valve chamber that communicates with these ports in the valve box using a valve body. In this directional control valve, the valve body is press-inserted into the valve chamber from the second valve seat through a hole provided in the valve box, and the valve body is configured with a valve member fixed to the circumference of the valve fitting. The valve member made of a flexible material is provided with an enlarged diameter part whose diameter is slightly smaller than the inner diameter of the second valve seat, and is fixed to the valve fitting so as to cover the enlarged diameter part. A first sealing part and a second sealing part are provided facing the valve seat, and a pair of circumferential protrusions with a diameter slightly larger than the inner diameter of the valve seat are provided around the first sealing part and the second sealing part. A directional switching valve characterized by having a valve groove that allows a peripheral protrusion to escape when a body is pressurized.
