Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a non-return type three-way valve which is convenient to switch. Background Art

[0002] Three-way valves, also known as three-way valves, are control components in fluid delivery systems, with functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow. Simply put, a three-way valve has three inlets and outlets, which are mainly controlled by the shape of the valve core. The three-way confluence has two inlets and one outlet, and the three-way diversion has one inlet and two outlets. However, the valve requires manual operation, and the opening, closing or direction of the fluid is controlled by rotating the valve handle. Since different installation positions often affect the operator's operation, a non-return type three-way valve that is easy to switch is needed.
