Description

Technical Field

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

[0002] Although the existing exhaust valves are equipped with filter meshes to filter gases, when the gas enters, if the gas flow rate is high, it will impact the filter mesh, easily damaging the filter mesh. Moreover, when the gas impacts the filter mesh, it will cause the filter mesh to vibrate and generate noise, bringing inconvenience to people's use. Content of the Utility Model

[0003] The purpose of the utility model is to provide a filtering exhaust valve in view of 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 exhaust valve, including an exhaust valve body, one end of which is an intake pipe and the other end is an outlet pipe. Flange plates are arranged on both the intake pipe and the outlet pipe. The innovation lies in that: a chuck is longitudinally arranged in the intake pipe. An annular groove is arranged on the outer surface of the chuck. A plurality of intake holes are annularly and arrayedly opened on the outer ring of the chuck. The intake holes are arranged around the annular groove. The end face of the intake pipe is bent inward to form an L-shaped structure to form a limiting ring. A filter cylinder is arranged between the limiting ring and the annular groove. Both ends of the filter cylinder are open, and one end is embedded in the annular groove for fixation, and the other end is connected to the limiting ring. A plurality of fastening bolts are annularly and arrayedly arranged outside the intake pipe. The fastening bolts extend into the intake pipe and fix the filter cylinder on the limiting ring.

[0005] Furthermore, a wind guiding body with a conical structure is arranged at the center of the outer surface of the chuck.

[0006] Furthermore, the intake holes are waist-shaped holes.

[0007] Furthermore, the fastening bolts adopt countersunk hole fits.

[0008] After adopting the above structure, the beneficial effects of the utility model are as follows:

[0009] The utility model arranges a chuck to buffer the gas, avoiding the gas directly impacting the filter cylinder. At the same time, the arrangement of the filter cylinder can also avoid the direct impact of the gas, reducing the noise generated by its vibration. Moreover, the filter cylinder is more firm and stable than the filter mesh with a planar structure and is not easily damaged. Description of the Drawings

[0011] Explanation of the Reference Numerals in the Drawings:

[0012] 1 Exhaust valve body, 2 Intake pipe, 3 Outlet pipe, 4 Flange, 5 Chuck, 6 Annular groove, 7 Air inlet hole, 8 Limit ring, 9 Filter cartridge, 10 Fastening bolt, 11 Air guide body. Detailed implementation manner

[0013] The following further explains the present utility model in conjunction with the attached drawings.

[0014] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the attached drawings and specific implementation manners. It should be understood that the specific implementation manners described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0015] Refer to Figure 1 , a filtering exhaust valve, including an exhaust valve body 1, one end of which is an intake pipe 2 and the other end is an outlet pipe 3. Flanges 4 are provided on both the intake pipe 2 and the outlet pipe 3. A chuck 5 is longitudinally arranged inside the intake pipe 2. An annular groove 6 is provided on the outer surface of the chuck 5. A plurality of air inlet holes 7 are arranged in an annular array on the outer ring of the chuck 5. The air inlet holes 7 are arranged around the annular groove 6. The end face of the intake pipe 2 is bent inward to form an L-shaped structure to form a limit ring 8. A filter cartridge 9 is arranged between the limit ring 8 and the annular groove 6. Both ends of the filter cartridge 9 are open, and one end is embedded in the annular groove 6 for fixation, and the other end is connected to the limit ring 8. A plurality of fastening bolts 10 are arranged in an annular array outside the intake pipe 2. The fastening bolts 10 extend into the intake pipe 2 and fix the filter cartridge 9 on the limit ring 8. Specifically, after the gas enters from the intake pipe 2, first, the chuck 5 can buffer the gas to avoid the gas directly impacting the filter cartridge 9. At the same time, the setting of the filter cartridge 9 can also avoid the gas directly impacting and reduce the noise generated by its vibration. Then the gas is transported to the air inlet holes 7 through the filter cartridge 9; the filter cartridge 9 is more firm and stable than a flat filter screen and is not easily damaged.

[0016] In this embodiment, a wind guide body 11 with a conical structure is arranged at the center of the outer surface of the chuck 5. While buffering the gas, the wind guide body 11 can guide the gas so that it is transported to the filter cartridge 9.

[0017] In this embodiment, the air inlet holes 7 are waist-shaped holes, and 2 - 3 air inlet holes can be used, so as to minimize the impact on gas transportation.

[0018] In this embodiment, the fastening bolts 10 adopt counterbore fits to improve aesthetics.

[0019] 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 should 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.
