Description

Technical Field

[0001] The utility model relates to the field of ventilation butterfly valves, in particular to a flange type ventilation butterfly valve with a sewage interception function. Background Art

[0002] Ventilation butterfly valves are used in dusty cold or hot air gas pipelines in ventilation and environmental protection projects in the chemical, building materials, power stations, glass and other industries as pipeline control devices for regulating the flow or cutting off the gas medium. This type of valve should generally be installed horizontally in the pipeline. The butterfly valve is a simple regulating valve and can also be used for the switch control of low-pressure pipeline media. The ventilation butterfly valve is a non-sealed butterfly valve. At present, when the ventilation butterfly valve is used to transport gas, the dust particles attached to the gas are transported to the working environment with the pump body. Therefore, the input gas needs to be filtered. The traditional flange ventilation butterfly valve uses a filter to filter the sewage. Although the filter can play a good filtering role, the filter is easy to clog after long-term use and needs to be cleaned frequently. The existing cleaning method is to remove the flange ventilation butterfly valve and then remove the filter to clean it. This method requires stopping the work of the flange ventilation butterfly valve. The cleaning process is relatively complicated and slow. For this reason, we propose a flange ventilation butterfly valve with sewage interception function. Utility Model Content

The vibration motor 10 is fixedly installed at the center position of the fixed circular plate 9. The working principle is: start the vibration motor 10 in the pollution intercepting component 4. After the vibration motor 10 is started, the vibration motor 10 will vibrate with the fixed circular plate 9 and the filter component 11 at a high frequency. Since the spring 8 is fixedly installed on the outer side of the fixed circular plate 9, the spring 8 can play a certain shock-absorbing role, so that when the gas remains in the filter component 11 or the impurities on the fixed circular plate 9, they will fall with the vibration of the vibration motor 10.

[0025] Furthermore, the filter assembly 11 includes a mounting block 12 and an air filter element 13. The mounting block 12 is funnel-shaped, and the larger end of the mounting block 12 is mounted on the outer wall of the fixed circular plate 9 on the side away from the butterfly valve 1, and the smaller end of the mounting block 12 is fixedly mounted with the air filter element 13.

The mounting block 12 is conical. When the gas enters, it will be gathered by the shape characteristics of the mounting block 12. When the gas is gathered by the mounting block 12 and enters the air filter element 13, the air filter element 13 will filter out large particles of impurities in the gas. After the gas passes through the air filter element 13, the impurities will be left in the air filter element 13 or fall vertically into the collection component 6 below due to the design of the inclined surface of the mounting block 12. After using the flange type ventilation butterfly valve for a period of time, we need to clean it. We first need to start the vibration motor 10 in the sewage interception component 4. When the vibration motor 10 is started, the vibration motor 10 will vibrate with the fixed circular plate 9 and the filter component 11 at a high frequency. Since the outer side of the fixed circular plate 9 is fixedly installed with a spring 8, and the spring 8 It can play a certain shock-absorbing role. When the impurities in the gas remaining on the filter component 11 or the fixed circular plate 9 will fall into the collection component 6 with the vibration of the vibration motor 10, and wait for the vibration work of the vibration motor 10 to be completed, we pull the collection box 15 out of the connection box 14 through the handle on the collection box 15.
