Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further explained below with reference to the following embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention, and not all embodiments are included. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
Specific embodiments of the present invention will be described below with reference to the accompanying drawings. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Referring to fig. 1, the full-guiding check valve comprises a valve cover 1, a valve body 7 and a valve clack 3, wherein the valve body 7 is provided with a water inlet 12, the valve cover 1 is provided with a water outlet 10, the valve cover 1 and the interior of the valve body 7 are communicated to form a cavity, the cavity is connected with the water inlet 12 and the water outlet 10, the valve clack 3 is arranged in the cavity, and a central guide ring 2 is fixedly arranged in the cavity; the valve clack 3 comprises a guide part 13 and a sealing part 14, the guide part 13 penetrates through the central guide ring 2, an O-shaped sealing ring 5 is sleeved on the sealing part 14, and the sealing part 14 is tightly attached to the water inlet 12 in a closed state of the valve; and a buffer spring 4 is arranged between the central guide ring 2 and the valve clack 3.
In one embodiment, referring to fig. 1, the inner wall of the upper end of the valve body 7 is provided with a groove body, the groove body forms a clamping groove when being combined with the bottom of the valve cover 1, and the end part of the central guide ring 2 is arranged in the clamping groove.
