Description

Technical Field

[0001] The utility model relates to the technical field of exhaust valves, and particularly relates to a filtering type exhaust valve. Background Art

[0002] During the use of the exhaust valve, since the liquid contains impurities, it is necessary to filter the liquid to avoid clogging the exhaust valve. Generally, a filter screen is used to filter the impurities at present. However, the existing filter screen has a small filtering area, resulting in poor filtering efficiency. At the same time, it is also inconvenient to disassemble and assemble. Therefore, improvements are needed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a filtering type exhaust valve aiming at the defects and deficiencies of the prior art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a filtering type exhaust valve, including a valve body. The innovation lies in that the bottom of the valve body is a liquid inlet, a valve core and an M-shaped filter screen are arranged in the liquid inlet. A fixing bolt is arranged at the center of the filter screen. The top of the fixing bolt extends into the valve core and is fixed by the fixing bolt. A floating ball is arranged inside the valve body.

[0005] Further, an overflow groove is formed between the filter screen and the inclined inner wall of the valve body.

[0006] Further, the valve core is of a hemispherical structure, and the inner wall is attached to the surface of the floating ball.

[0007] After adopting the above structure, the beneficial effects of the utility model are as follows:

[0008] By arranging the M-shaped filter screen, the utility model can increase the filtering area, improve the filtering efficiency and quality. At the same time, the installation and disassembly are facilitated by using fixing bolts and fixing nuts. Description of the Drawings

[0012] 1 valve body, 2 valve core, 3 filter screen, 4 fixing bolt, 5 fixing bolt, 6 floating ball, 7 overflow groove. Detailed Embodiment

[0013] The following further describes the utility model with reference to the drawings.

[0014] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0015] Referring to Figure 1 , a filtering exhaust valve, comprising a valve body 1. The bottom of the valve body 1 is a liquid inlet, and a valve core 2 and an M-shaped filter screen 3 are arranged in the liquid inlet. A fixing bolt 4 is arranged at the center of the filter screen 3, and the top of the fixing bolt 4 extends into the valve core 2 and is fixed by a fixing bolt 5. A floating ball 6 is arranged inside the valve body 1. Specifically, since the upper surface and the outer ring of the M-shaped filter screen 3 both have filtering functions, the filtering area can be increased, thereby improving the filtering efficiency and filtering quality. At the same time, the fixing bolt 5 is limited and installed in the valve core, and the fixing bolt 4 is arranged inside the filter screen 3, so that the installation and disassembly can be carried out from the bottom of the filter screen 3, improving the convenience.

[0016] In this embodiment, an overflow groove 7 is formed between the filter screen 3 and the inclined inner wall of the valve body 1. The overflow groove 7 is used to increase the overflow area, thereby improving the filtering effect.

[0017] In this embodiment, the valve core 2 is of a hemispherical structure, and the inner wall is attached to the surface of the floating ball 6, thereby improving the sealing performance.

[0018] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model shall be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
