Description

Technical Field

[0001] This utility model relates to the field of butterfly valve technology, and more specifically, to a butterfly valve with a cleaning function. Background Technology

[0002] A butterfly valve is a simple regulating valve that is frequently used to control the flow rate in pipelines transporting liquids. Due to its rapid opening and closing and simple operation, the butterfly valve has become a commonly used device in pipeline liquid transportation.

[0003] However, traditional butterfly valves lack a cleaning and filtration structure, leaving impurities from the water inside. Impurities and dirt also accumulate at the seals between the valve cavity and the butterfly plate, and these build-up increases over time, affecting the quality of the medium passing through the valve cavity. Therefore, to address these issues, a butterfly valve with a cleaning function is proposed. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a butterfly valve with a cleaning function, which has a cleaning and filtering structure, making it easy for people to clean impurities inside the butterfly valve.

[0006] (2) Technical solution

[0007] To achieve the above objectives, this utility model provides a butterfly valve with a cleaning function, comprising a butterfly valve body, a first mounting ring, and a second mounting ring. Mounting discs are fixedly connected to both ends of the butterfly valve body. Multiple mounting holes are formed inside the mounting discs. Mounting ring grooves are formed on the inner side of the mounting rings. The first and second mounting rings are respectively engaged within the two mounting ring grooves. A first filter basket and a second filter basket are fixedly connected to the sides of the first and second mounting rings, respectively. A flat filter plate and an arc-shaped filter plate are respectively provided inside the first and second filter baskets. A rotating handle is provided inside the butterfly valve body. A valve stem is fixedly connected to the bottom of the rotating handle. Two butterfly plates and two connecting rods are fixedly connected to the surface of the valve stem. A cleaning scraper is fixedly connected to one end of each of the two connecting rods.

[0008] When using a butterfly valve with a cleaning function according to this technical solution, by setting a first filter basket, a second filter basket, and a cleaning scraper, impurities in the fluid can be filtered under the action of the first filter basket, reducing the impact of impurities on the butterfly valve. When the butterfly plate rotates or opens, it can drive the connecting rod and the cleaning scraper to rotate. Through the rotation of the cleaning scraper, impurities attached to the part of the valve cavity and the butterfly plate seal can be scraped off, which can prevent impurities from accumulating and sticking. Then, under the action of the second filter basket, the scraped impurities can be filtered.

[0009] Furthermore, a connecting slot is provided on the inner side of the mounting ring groove. The first mounting ring and the second mounting ring have the same structure. A connecting block is fixedly connected to the surface of the first mounting ring, and the connecting block is engaged in the connecting slot.

[0010] Furthermore, the connecting block has two movable slots inside, and fixing holes are provided on both sides of the connecting slots.

[0011] Furthermore, a through hole is provided on the inner side of the movable groove, and a limit spring is fixedly connected to the inner side of the movable groove.

[0012] Furthermore, one end of the limiting spring is fixedly connected to a toggle plate, the toggle plate is slidably connected in the through hole, and a fixing block is fixedly connected to the side of the toggle plate.

[0013] Furthermore, one end of the fixing block slides through the movable groove and engages with the fixing hole.

[0014] (3) Beneficial effects

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. This butterfly valve with cleaning function, by setting a first filter basket, a second filter basket and a cleaning scraper, can filter impurities in the fluid under the action of the first filter basket, reducing the impact of impurities on the butterfly valve. When the butterfly plate rotates and opens, it can drive the connecting rod and the cleaning scraper to rotate. Through the rotation of the cleaning scraper, impurities attached to the part of the valve cavity and the butterfly plate seal can be scraped off, which can prevent impurities from accumulating and sticking. Then, under the action of the second filter basket, the scraped impurities can be filtered.

[0017] 2. This butterfly valve with cleaning function has a toggle plate. When the toggle plate is pressed, the fixing block can be disengaged from the fixing hole.

Mounting discs 2 are fixedly connected to both ends of the butterfly valve body 1. Multiple mounting holes 201 are opened inside the mounting discs 2. Mounting ring grooves 202 are opened on the inner side of the mounting rings. The first mounting ring 3 and the second mounting ring 5 are respectively engaged in the two mounting ring grooves 202. A first filter basket 4 and a second filter basket 8 are fixedly connected to the side of the first mounting ring 3 and the side of the second mounting ring 5, respectively. A flat filter plate 6 and an arc-shaped filter plate 7 are respectively provided inside the first filter basket 4 and the second filter basket 8. A rotating handle 101 is provided inside the butterfly valve body 1. A valve stem 102 is fixedly connected to the bottom of the rotating handle 101. Two butterfly plates 103 and two connecting rods 104 are fixedly connected to the surface of the valve stem 102. A cleaning scraper 105 is fixedly connected to one end of each of the two connecting rods 104.

[0037] By adopting the above technical solution, and by setting the toggle plate 305, when people press the toggle plate 305, the fixing block 306 can be disengaged from the fixing hole 204. After disengagement, it is convenient for people to remove the first mounting ring 3 and the second mounting ring 5 from the two mounting ring grooves 202 respectively. At the same time, under the snapping action of the limit spring 303, the fixing block 306 and the fixing hole 204, it is convenient for people to stabilize the position of the first mounting ring 3 and the second mounting ring 5.

[0038] See Figure 2 and Figure 5 The inner side of the mounting ring groove 202 is provided with a connecting slot 203. The first mounting ring 3 and the second mounting ring 5 have the same structure. A connecting block 304 is fixedly connected to the surface of the first mounting ring 3. The connecting block 304 is engaged in the connecting slot 203. Two movable slots 301 are provided inside the connecting block 304. Fixing holes 204 are provided on opposite sides inside the connecting slot 203. A through hole 302 is provided inside the movable slot 301. A limit spring 303 is fixedly connected to the inside side of the movable slot 301. A toggle plate 305 is fixedly connected to one end of the limit spring 303. The toggle plate 305 is slidably connected in the through hole 302. A fixing block 306 is fixedly connected to the side of the toggle plate 305.
