The technical scheme of the utility model is as follows: the one-way valve with the O-shaped ring anti-falling structure comprises a valve sleeve and a valve seat, wherein the valve sleeve is arranged at the upper end of the valve seat, a valve core is further arranged in the valve sleeve and the valve seat, a spring is further sleeved on the valve core, and an O-shaped ring groove is formed between the valve sleeve and the valve seat; an O-shaped ring is sleeved in the O-shaped ring groove;
the lower end of the valve sleeve is provided with a first limiting bevel edge for limiting the O-shaped ring; the upper end of the valve seat is provided with a second limiting bevel edge for limiting the O-shaped ring.
As a preferable example, the included angle between the first limiting oblique side and the high wall of the O-shaped ring groove is 110 degrees.
As a preferable mode of the embodiment, the included angle between the second limiting oblique side and the wide wall of the O-shaped ring groove is 120 degrees.
As preferable in this embodiment, the first limiting oblique edge and the second limiting oblique edge are both round chamfer structures.
As the preferred radius of the embodiment, the radii of the upper and lower round chamfer structures of the first limit inclined edge and the second limit inclined edge are respectively 0.1mm and 0.2mm.
Preferably, the valve sleeve and the valve seat form an O-shaped ring groove through interference fit, and the interference is 0.015-0.025mm.
As a preferable example, the width of the wide wall of the O-shaped ring groove is 1.56mm, and the height of the high wall of the O-shaped ring groove is 1.85mm.
The beneficial effects of the utility model are as follows:
1. the O-shaped ring can be effectively fixed by utilizing the first limiting bevel edge and the second limiting bevel edge, so that the problem of falling off of the O-shaped ring is avoided;
2. the O-shaped ring is placed in the O-shaped ring groove and can deform, and because the deformed O-shaped ring can squeeze the height and the width walls of the O-shaped ring groove by adopting the limiting bevel edge, the bevel edge counteracts the O-shaped ring, so that the forces of the O-shaped ring in the vertical direction are mutually counteracted, and finally the force born by the O-shaped ring is a component force in the horizontal direction, thereby avoiding the O-shaped ring from falling off.
