Description

Technical Field

[0001] This utility model relates to the field of marine exhaust valve coal ash cleaning technology, specifically to a convenient exhaust valve coal ash cleaning device. Background Technology

[0002] Marine exhaust valves are specially designed exhaust devices for ship piping systems. Their main function is to release air and gases from the piping system, ensuring its normal operation and safety. Marine exhaust valves are typically installed on the outer side of the upper deck of a ship to allow exhaust gases to be released into the atmosphere.

[0003] Classification societies require that the exhaust valve be equipped with a coal ash cleaning device. Self-cleaning valves have a relatively complex structure, large size, and high cost. The installation of self-cleaning valves requires a classification society certificate, which takes a long time to be issued.

[0004] Therefore, there is a need to provide a convenient exhaust valve coal ash cleaning device. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a convenient coal ash cleaning device for exhaust valves. The purpose is to reduce costs and improve efficiency by configuring the coal ash cleaning device on the exhaust valve, achieving the desired effect through an easy-to-operate method.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a convenient exhaust valve coal ash cleaning device, comprising an exhaust pipe, an exhaust valve, and a cleaning branch pipe. The exhaust pipe is equipped with an exhaust valve, and a cleaning branch pipe is connected to one side of the exhaust valve. A flange is provided at the end of the cleaning branch pipe, and a sealing groove is provided inside the end of the cleaning branch pipe. A sealing ring is provided inside the sealing groove. A sealing groove is provided on the end face of the flange, and a sealing ring is provided inside the sealing groove. A blind flange is fixedly connected to the flange. A sealing protrusion is provided on the end face of the blind flange near the flange. The sealing protrusion is inserted into the cleaning branch pipe, and the outer surface of the sealing protrusion is in sealing contact with the sealing ring. The surface at the connection between the sealing protrusion and the blind flange is in sealing contact with the sealing ring.

[0007] Preferably, the blind flange and flange one are fixedly connected by bolts.

[0008] Preferably, the end face of flange one is circumferentially distributed with snap-fit ​​bases, and the side circumferential surface of the blind flange is provided with a plug-in hook plate corresponding to the snap-fit ​​base. The plug-in hook plate is snapped and installed inside the snap-fit ​​base, and the plug-in hook plate abuts against the inside of the snap-fit ​​base by the elastic action of sealing ring two.

[0009] Preferably, the number of snap-fit ​​bases is four, and the number of corresponding plug-in hook plates is four.

[0010] In summary, this utility model provides a convenient coal ash cleaning device for exhaust valves. The technical approach adopted by this utility model patent is as follows: a cleaning branch pipe is provided on one side of the exhaust valve, which is blinded by a blind flange. When ash cleaning is required, the blind flange is opened, and air or water is used for cleaning. The end face of the blind flange is provided with a sealing protrusion, which is in sealing contact with sealing ring one, and sealing ring two is in sealing contact with the end face of the blind flange. The blind flange and flange one are fixedly installed, achieving a sealed installation between the blind flange and the cleaning branch pipe. When ash cleaning is required, the blind flange is opened, and air or water is used for cleaning, thereby reducing costs, improving efficiency, and achieving the desired effect through an easy-to-operate method.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figures 1 to 3 As shown:

[0017] This utility model is a convenient exhaust valve coal ash cleaning device, including an exhaust pipe 1, an exhaust valve 2, and a cleaning branch pipe 3. The exhaust pipe 1 is equipped with the exhaust valve 2, and the cleaning branch pipe 3 is connected to one side of the exhaust valve 2. A flange 4 is provided at the end of the cleaning branch pipe 3. A sealing groove 5 is opened inside the end of the cleaning branch pipe 3, and a sealing ring 6 is installed inside the sealing groove 5. A sealing groove 7 is opened on the end face of the flange 4, and a sealing ring 11 is installed inside the sealing groove 7. A blind flange 12 is fixedly connected to the flange 4. A sealing protrusion 13 is provided on the end face of the blind flange 12 near the flange 4. The sealing protrusion 13 is inserted and installed inside the cleaning branch pipe 3, and the outer surface of the sealing protrusion 13 is in sealing contact with the sealing ring 6.
