Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a one-way stop valve used in an automobile cooling system. Background Art

[0002] The primary function of a car's cooling system is to dissipate heat into the air to prevent engine overheating. This system primarily circulates fluid through pipes and pathways within the engine. As the fluid flows through the hot engine, it absorbs heat, thereby reducing engine temperature. One-way shut-off valves are installed in the cooling system's piping to intercept the flow. Conventional shut-off valves only reduce flow but cannot control flow rate. Furthermore, since these valves are completely inserted into the piping, it is difficult to determine the direction of flow control. Utility Model Content

[0003] To solve the above technical problems, the present invention provides a one-way stop valve for an automobile cooling system, comprising a main body (I) and a main body (II) connected to each other; a steel ball is disposed between the main body (I) and the main body (II); a semicircular groove corresponding to the steel ball is disposed radially inwardly of the main body (I), and the outer diameter of the semicircular groove is consistent with the outer diameter of the steel ball;

[0004] The outer ring of the main body is provided with an arrow mark to facilitate identification of the flow direction and avoid reverse installation.

[0005] Among them, the main body 1 has a circular connecting head 1, the main body 2 has a circular connecting head 2, and the connecting head 2 has an annular slot, the radius size of the slot is consistent with the radius size of the connecting head 1, and the laser welding connection between the main body 1 and the main body 2 is achieved by snapping the connecting head 1 into the slot.

[0006] Wherein, the radial outer ring of the main body 1 is also provided with a limiting convex ring to limit the pipe insertion depth and avoid covering the arrow mark.

[0007] Through the above technical solution, the utility model can effectively control the coolant flow under different pressures through the built-in steel balls, and there is a flow direction arrow mark on the outside of the product to facilitate identification of the flow direction to avoid reverse installation.
