Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0046] Please refer to Figures 1-6 The utility model provides a new technical scheme: a multifunctional butterfly valve assembly, comprising an installation pipe 1, the outer surface of the installation pipe 1 is fixedly provided with two first flange plates 2;

[0047] The front and rear outer surfaces of the installation pipe 1 are both provided with installation grooves 3.

[0048] The upper surface of the installation pipe 1 is fixedly connected with a fixed pipe 7.

[0049] The fixed pipe 7 is communicated with the inside of the installation pipe 1.

[0050] The installation pipe 1 is provided with a dismounting mechanism and a scale inhibition mechanism, and the scale inhibition mechanism comprises an inner ceramic ring 4, a baffle 5, a sealing ring 13 and a rubber ring 14.

[0051] The dismounting mechanism comprises a second flange plate 8, a control box 10, a connecting hole 15, a positioning hole 17, a positioning block 6, a worm 18, a rotating groove 12, a fixing bolt 19, a worm wheel 16, a mounting bolt 9 and a control rod 11.

[0052] Further, the control box 10 is arranged on the upper side of the fixed pipe 7.

[0053] The two second flange plates 8 are fixedly connected on the fixed pipe 7 and the control box 10.

[0054] The two second flange plates 8 are fixedly connected through a plurality of mounting bolts 9.

[0055] The baffle 5 is arranged in the installation pipe 1.

[0056] The outer surface of the baffle 5 is provided with a sealing ring, and the sealing ring is slidably connected with the inner wall of the inner ceramic ring 4.

[0057] Further, the positioning block 6 is fixedly connected to the baffle 5;

[0058] Wherein, the rotating groove 12 is arranged on the upper surface of the positioning block 6;

[0059] Wherein, the rotating groove 12 extends downwardly beyond the lower surface of the positioning block 6;

[0060] Wherein, the control rod 11 is slidingly sleeved in the fixed tube 7, and the lower end of the control rod 11 slidingly penetrates into the installation tube 1 and is in sliding connection with the rotating groove 12;

[0061] Wherein, two positioning holes 17 are arranged on the outer surface of the control rod 11.

[0062] Further, two fixing bolts 19 are threadedly connected to the positioning block 6, and the fixing bolts 19 threadedly penetrate into the rotating groove 12;

[0063] Wherein, the two fixing bolts 19 slidingly extend into the two positioning holes 17,

[0064] Wherein, the upper end of the control rod 11 rotatably penetrates into the control box 10;

[0065] Wherein, the worm gear 16 is fixedly connected to the upper end of the control rod 11;

[0066] Wherein, the worm 18 is rotatably connected to the control box 10, and the worm 18 is in meshing connection with the worm gear 16.

[0067] Further, the inner ceramic ring 4 is slidingly sleeved in the installation tube 1;

[0068] Wherein, the inner ceramic ring 4 is in sliding connection with the front mounting groove 3;

[0069] Wherein, two connecting holes 15 are arranged on the upper and lower outer surfaces of the inner ceramic ring 4;

[0070] Wherein, the two connecting holes 15 are mirror image arranged, and the two connecting holes 15 are in communication with the inside of the inner ceramic ring 4.

[0071] Further, a sealing member is arranged in the connecting hole 15;

[0072] Wherein, the two connecting holes 15 are in sliding connection with the control rod 11;

[0073] Wherein, the sealing ring 13 is slidingly connected in the rear mounting groove 3;

[0074] Wherein, the rubber ring 14 is fixedly connected to the front surface of the sealing ring 13, and the rubber ring 14 is in sliding connection with the inner wall of the rear mounting groove 3.

[0075] Furthermore, in this solution, the inner wall of the butterfly valve assembly is made of materials with high hardness, high wear resistance, and high oxidation resistance, and has good corrosion resistance to acids, alkalis, and salts. The ceramic glaze is smooth and has good anti-scaling properties, making it more practical than traditional metal inner walls and ensuring the service life of the butterfly valve assembly.

[0076] As mentioned above, rotating the worm gear 18 causes the worm wheel 16 to rotate, which in turn causes the control rod 11 to rotate, which in turn causes the baffle 5 to rotate, which in turn causes the baffle 5 to close or open the mounting pipe 1, thereby controlling the opening and closing of the butterfly valve.

[0077] As mentioned above, when it is necessary to clean the scale inside the inner ceramic ring 4, the baffle 5 needs to be removed. First, the mounting bolt 9 needs to be removed, then the control box 10 needs to be separated from the fixing pipe 7, and then the fixing bolt 19 needs to be removed. Pull the control box 10 upwards, and pull the upper side of the control rod 11 out of the rotating groove 12 until the control rod 11 is pulled out of the mounting pipe 1, and then the control rod 11 is also pulled out of the connecting hole 15. Then the control rod 11 and the baffle 5 are separated, and the baffle 5 can be pushed out of the mounting pipe 1, or the inner ceramic ring 4 can be slid out of the mounting pipe 1, which makes it easier to clean the scale inside the inner ceramic ring 4. Because the inner ceramic ring 4 has good corrosion resistance and a smooth ceramic glaze, it has good anti-scaling performance. Therefore, the inner ceramic ring 4 is easier to clean than the inner wall of the traditional metal butterfly valve, and the cleaning effect is better. This helps to improve the service life of the butterfly valve assembly and increase the multi-functionality of the butterfly valve.

[0078] As mentioned above, in this solution, during installation, the first flange 2 on the front side needs to be fixed to the pipe to be connected. During this process, the inner ceramic ring 4 can be fixed. When installing the first flange 2 on the rear side, the rubber ring 14 and the sealing ring 13 can increase the sealing between the inner ceramic ring 4 and the installation pipe 1, thereby improving the sealing between the installation pipe 1 and the inner ceramic ring 4 and increasing the practicality of the butterfly valve.

[0079] Working principle: When the device is in use, the inner wall of the butterfly valve assembly is made of high hardness, high wear resistance, and high oxidation resistance, and has good corrosion resistance to acids, alkalis and salts. The ceramic glaze is smooth and has good anti-scaling properties. It is more practical than the traditional metal material inner wall and ensures the service life of the butterfly valve assembly.

[0080] As mentioned above, rotating the worm gear 18 causes the worm wheel 16 to rotate, which in turn causes the control rod 11 to rotate, which in turn causes the baffle 5 to rotate, which in turn causes the baffle 5 to close or open the mounting pipe 1, thereby controlling the opening and closing of the butterfly valve.

[0081] As mentioned above, when it is necessary to clean the scale inside the inner ceramic ring 4, the baffle 5 needs to be removed. First, the mounting bolt 9 needs to be removed, then the control box 10 needs to be separated from the fixing pipe 7, and then the fixing bolt 19 needs to be removed. Pull the control box 10 upwards, pulling the upper side of the control rod 11 out of the rotating groove 12, until the control rod 11 is pulled out of the mounting pipe 1, and then the control rod 11 is also pulled out of the connecting hole 15. Then the control rod 11 and the baffle 5 are separated, and the baffle 5 can be pushed out of the mounting pipe 1, or the inner ceramic ring 4 can be slid out of the mounting pipe 1, which facilitates the cleaning of scale inside the inner ceramic ring 4. Because the inner ceramic ring 4 has good corrosion resistance and a smooth ceramic glaze, it has good anti-scaling performance. Therefore, the inner ceramic ring 4 is easier to clean than the inner wall of the traditional metal butterfly valve, and the cleaning effect is better, which helps to improve the service life of the butterfly valve assembly and increase the multi-functionality of the butterfly valve.
