Description

Technical Field

[0001] This utility model relates to the field of butterfly valve technology, specifically a butterfly valve with a multi-layer filtration mechanism. Background Technology

[0002] A butterfly valve is a fluid control device widely used in industrial pipeline systems. It is opened, closed or adjusted by rotating 90 degrees. The liquid flowing inside the butterfly valve may contain impurities. If it is not filtered, it may be difficult to use or affect the quality of the liquid.

[0003] Currently, butterfly valves still have some shortcomings, such as being inconvenient for water filtration:

[0004] To overcome the shortcomings of water filtration, a novel slag-collecting butterfly valve is disclosed in Chinese patent (publication number: CN212509574U). This valve features three filter layers with different filtration precisions, ensuring rapid water outflow while simultaneously recovering solid particles. The hollow valve stem and butterfly plate not only discharge water but also serve as channels for providing high-pressure gas or cleaning agents for backflushing or backwashing. An inflatable sealing ring is installed on the inner wall of the valve body, allowing for inflation after the butterfly plate is closed, maintaining good sealing performance and enhancing durability.

[0005] However, the butterfly valves currently in use still have certain shortcomings. As mentioned above, it is inconvenient to handle impurities in the butterfly valves. Secondly, the accumulation of impurities will affect the water flow efficiency, thus affecting the normal use of the butterfly valves. Furthermore, some butterfly valves with filters have the filter mechanism connected to the butterfly valve, which will affect the installation efficiency of the butterfly valves. Therefore, it is necessary to improve the existing structure. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1, such as Figures 1-4 The present invention provides the following technical solution to address the problem that butterfly valves are inconvenient for water filtration and thus affect water quality: A filtration mechanism is disclosed.

[0031] The valve body includes a valve body 1, a handle 2 connected to its surface, a butterfly plate 3 fixed to the bottom of the handle 2, the butterfly plate 3 rotating inside the valve body 1, a connecting pipe 101 connected to the side of the valve body 1, a first filter plate 102 installed inside the connecting pipe 101, a second filter plate 103 connected to the inside of the connecting pipe 101 away from the first filter plate 102, a water filtration mechanism inside the connecting pipe 101, eight sets of fixing blocks 110 fixed to the outside of the flange of the connecting pipe 101, threaded blocks 111 threaded through the fixing blocks 110, and a side of the connecting pipe 101... The butterfly valve has a squeezing mechanism to improve the installation efficiency of the filtration mechanism. When the butterfly valve is in use, the water flow can be delivered to the valve body 1 through the connecting pipe 101. The operator can turn the handle 2. When the handle 2 is turned, it can drive the butterfly plate 3 to rotate inside the valve body 1. When the butterfly plate 3 rotates, the butterfly valve can be opened, thus realizing the use of water. When the water flows through the connecting pipe 101, the impurities in the water flow can be filtered by the first filter plate 102 and the second filter plate 103. The first filter plate 102 and the second filter plate 103 have different filtration precisions, which can realize the multiple filtration effects of the butterfly valve.

[0032] Example 2, as follows Figure 2 , Figure 4 and Figure 5 The present invention provides the following technical solution to address the problem that the filtration mechanism is inconvenient for collecting and processing impurities, which affects water flow efficiency: A cleaning mechanism is disclosed.

[0033] The connecting pipe 101 is equipped with a cleaning mechanism for removing impurities. This mechanism includes a rotating rod 104 that rotates through the first filter plate 102 and the second filter plate 103. Two sets of cleaning plates 105 are fixed to the surface of the rotating rod 104, respectively abutting against the sides of the first and second filter plates 102 and 103. An impeller 106 is fixed to the end of the rotating rod 104 away from the first filter plate 102. A collection trough 107 is formed through the connecting pipe 101 near the inner side of the first and second filter plates 102 and 103. A water outlet cylinder 108 is fixed to the side of the connecting pipe 101 near the port of the collection trough 107. A sealing cap 109 is threaded onto the surface of the water outlet cylinder 108. When the water flows through the butterfly valve, it can drive the impeller 106 to rotate. The rotation of the impeller 106 can then drive the rotating rod 104 to rotate, allowing water to pass through the valve. As the first filter plate 102 and the second filter plate 103 rotate, the rotating rod 104 rotates, which drives the cleaning plate 105 to rotate. When the cleaning plate 105 rotates, it can clean the impurities on the sides of the first filter plate 102 and the second filter plate 103. After the impurities are cleaned, the flow effect of the first filter plate 102 and the second filter plate 103 can be guaranteed. After the impurities are cleaned, they can fall into the collection tank 107 for collection. After the connecting pipe 101 has been used for a period of time, the sealing cover 109 is rotated. When the sealing cover 109 rotates, it can slide through the water outlet cylinder 108. After the sealing cover 109 slides out of the surface of the water outlet cylinder 108, it can be disassembled. After the sealing cover 109 is disassembled, the water inside the connecting pipe 101 can flow out through the collection tank 107. The impurities accumulated in the collection tank 107 will also be flushed out. In this way, the impurities are cleaned, which makes it convenient for the butterfly valve to clean the impurities filtered.

[0034] Example 3, as follows Figure 1 , Figure 2 , Figure 6 and Figure 7 The present invention provides the following technical solution to address the problem that the filter mechanism of a butterfly valve is inconvenient to disassemble and assemble, thus affecting its efficiency: A compression mechanism is disclosed.

[0035] The extrusion mechanism includes a connecting block 112. The end of the connecting block 112 away from the connecting pipe 101 is fixed with the connecting block 112. Eight sets of through grooves 113 are opened through the flange side of the valve body 1. A first sliding groove 115 is opened on the side of the connecting block 112. A telescopic block 114 slides through the first sliding groove 115. A spring is connected between the telescopic block 114 and the first sliding groove 115. A positioning groove 116 is opened on the side of the first sliding groove 115. A second sliding groove 117 is opened through the bottom of the telescopic block 114. A sliding block 118 slides through the second sliding groove 117.

[0036] Before using the butterfly valve, move the connecting pipe 101 to the front of the flange of the valve body 1. The connecting pipe 101 can move the connecting block 112 to the side of the through groove 113. Pushing the connecting pipe 101 can cause the connecting block 112 to be inserted into the through groove 113. When the connecting block 112 is inserted, it can cause the telescopic block 114 to tilt and press against the inner wall of the through groove 113. When the telescopic block 114 is pressed, it can slide through the first sliding groove 115. When the telescopic block 114 slides, it can press the spring. After the telescopic block 114 is pressed into the first sliding groove 115, the connecting block 112 can slide inside the through groove 113. When the connecting block 112 drives the telescopic block 114 to slide out of the through groove 113, the telescopic block 114 can be reset under the action of the spring. When the telescopic block 114 is reset, it can be moved to the back of the flange of the valve body 1 for positioning. At this time, the connecting pipe 101 can be moved to the side of the valve body 1 for close connection. However, the connection between the connecting pipe 101 and the valve body 1 is unstable. The connecting block 112 can be rotated at regular intervals. When the connecting block 112 rotates, it can drive the threaded block 111 to rotate. When the threaded block 111 rotates, it can slide through the fixed block 110. When the connecting block 112 slides through the thread, it can drive the telescopic block 114 to press against the flange of the valve body 1. When the telescopic block 114 presses, it can drive the connecting pipe 101 to fit tightly against the valve body 1, thus realizing the installation of the connecting pipe 101. When the connecting pipe 101 is disassembled, the telescopic block 114 can be pushed into the first sliding groove 115 by hand. When the telescopic block 114 is pushed, it can drive the sliding block 118 to move to the side of the positioning groove 116. Then, push the sliding block 118 to slide through the second sliding groove 117 into the positioning groove 116. The sliding block 118 can then drive the telescopic block 114 to be positioned inside the first sliding groove 115. Then, pull the connecting pipe 101, and the connecting pipe 101 can be separated from the valve body 1. This improves the efficiency of the disassembly and assembly of the connecting pipe 101 and enhances the ease of use.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
