Detailed Description

In order that the objects and advantages of the invention will be more clearly understood, the invention is further described below with reference to examples; it should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and do not limit the scope of the present invention.

It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are only for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1-7, the anti-leakage valve comprises a sleeve ring and a pipe body, wherein the pipe body comprises a pump pipe connector and a valve pipe connector, the pump pipe connector comprises a leakage-proof groove and a connecting buckle, the leakage-proof groove comprises a first leakage-proof groove and a second leakage-proof groove, the connecting buckle is sleeved on the pipe body, the connecting buckle is circular, an annular groove is arranged in the connecting buckle, a pipe locking spring is arranged in the annular groove, and the valve pipe connector and the pump pipe connector are consistent in size and shape.
