Description

Technical Field

[0001] The utility model belongs to the technical field of butterfly valves, in particular to a butterfly valve which is easy to clean. Background Art

[0002] A butterfly valve, also known as a flap valve, is a regulating valve with a simple structure that can be used for on-off control of low-pressure pipeline media. A butterfly valve refers to a valve with a closing member as a disc that rotates around the valve axis to achieve opening and closing. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. However, after long-term use, impurities are easily accumulated on the inner wall of the butterfly valve, which affects the normal closing of the valve and the normal use of the valve. In order to maintain the normal use of the valve, a butterfly valve that is easy to clean is required.

[0003] Based on the findings in the prior art, the existing butterfly valve is usually cleaned by disassembly, which requires the valve parts to be replaced during the cleaning process, making the cleaning process too complicated and inconvenient to use. Utility Model Content

[0014] 1. In the present invention, a retention groove and a blocking block are provided. By providing leak-proof grooves at equal intervals on the outer wall of the valve body, the blocking block can be fixed by means of threads. After the blocking block is removed, it is connected to the flushing pipe, so that impurities in the retention groove can be flushed out by flushing water into the interior, thereby preventing the flap from being blocked by excessive accumulation of impurities. By providing a retention groove on the inner wall of the valve body, internal impurities can be temporarily retained and processed during liquid transportation, thereby reducing the impact of impurities on the flap.

The large particles of impurities blocked by the external sealing plate can be cleaned;

[0017] 4. By setting up the inner punching hole and the retention groove, when the liquid is transported, the retained impurities are temporarily stored in the retention groove to reduce the impact on the rotation of the flap, and by connecting the retention groove with the inner punching hole, it is convenient to directly connect to the external water pipe through the inner punching hole to flush the impurities in the groove, so as to facilitate the cleaning of internal impurities without disassembly.
