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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] Specific implementation examples are given below.
[0027] like Figures 1 to 4As shown in the embodiment of this utility model, a multi-layer leak-proof integrated butterfly valve includes a first valve body 1. A second rubber ring 9 is provided inside the first valve body 1, and a butterfly valve disc 8 is mounted on the second rubber ring 9. The outer wall of the butterfly valve disc 8 is tightly fitted to the inner wall of the second rubber ring 9. A second rotating shaft 16 is horizontally connected to the bottom of the butterfly valve disc 8. The second rotating shaft 16 passes through the second rubber ring 9 and through an opening in the side wall of the first valve body 1. The second rotating shaft 16 is connected to the output end of a motor 5, and the output end of the motor 5 is connected to the opening in the side wall of the first valve body 1. The first valve body 1 and the motor 5 are fixed by a first bolt 7. A second valve body 2 is connected to the top of the first valve body 1. Six fixing blocks 17 are fixed to the outer wall of the top of the first valve body 1, and these fixing blocks 17 are evenly distributed in a circumferential array. The outer wall of the second valve body 2 is also fixed to six fixing blocks 17, which are arranged in a circumferential array. The array is evenly distributed, with corresponding fixing blocks 17 on the outer walls of the first valve body 1 and the second valve body 2. Each fixing block 17 has a circular hole inside, into which a first bolt 7 is installed. A hexagonal nut 6 is rotatably installed at the bottom of the first bolt 7. During operation, the motor 5 is started, and its output drives the second rotating shaft 16 to rotate. The second rotating shaft 16 then rotates the butterfly valve plate 8, opening the valve. The motor 5 is started again, and its output drives the second rotating shaft 16 to rotate, again rotating the butterfly valve plate 8. Because the second rubber ring 9 is made of rubber, the outer wall of the butterfly valve plate 8 fits tightly against the inner wall of the second rubber ring 9 after rotation, closing the valve and preventing leakage. The rubber material of the second rubber ring 9 also reduces leakage in the connection structure between the first valve body 1 and the second valve body 2. Through this structure, the valve opening and closing is electrically driven, and the rubber material further enhances the device's leak-proof performance and practicality.
[0028] like Figures 1 to 2As shown, the bottom of the first valve body 1 is connected to the bottom of the third valve body 3. A fixing block 17 is fixedly attached to the outer wall of the bottom of the first valve body 1. Six fixing blocks 17 are evenly distributed in a circular array. The fixing blocks 17 on the outer walls of the first valve body 1 and the third valve body 3 are also evenly distributed in a circular array. The fixing blocks 17 on the outer walls of the first valve body 1 and the third valve body 3 correspond to each other. The top of the second valve body 2 is connected to the bottom of the third valve body 3. A fixing block 17 is fixedly attached to the outer wall of the second valve body 2.

A hexagonal nut 6 is rotatably installed on the bottom of the first bolt 7. The fixing blocks 17 on the outer wall of the bottom of the third valve body 3 are also evenly distributed in a circular array. The fixing blocks 17 on the wall are corresponding to each other. Each fixing block 17 has a circular hole inside, and a first bolt 7 is installed in the circular hole. A hexagonal nut 6 is rotatably installed on the bottom of the first bolt 7. A second bolt 11 is provided on the top of the third valve body 3. The second bolt 11 passes through the top of the third valve body 3. There are six second bolts 11, which are evenly distributed in a circumferential array. During operation, the cooperation of the first bolt 7 and the hexagonal nut 6 makes the second valve body 2 and the third valve body 3 on the top of the first valve body 1 tightly connected to the first valve body 1. The cooperation of the first bolt 7 and the hexagonal nut 6 makes the first valve body 1 at the bottom of the first valve body 1 tightly connected to the third valve body 3. The required external pipe is connected through the second bolt 11 on the top of the third valve body 3. When the second bolt 11 is rotated, the third valve body 3 fits tightly with the external pipe. Through the above structure, the operation of the external pipe of the device is simplified, and the practicality of the device is increased.
[0029] like Figures 1 to 2 and Figures 5 to 6 As shown, the top of the third valve body 3 has a slot, and the outer wall of the slot has a metal cable tie 10. The metal cable tie 10 has two sets of rings. The metal cable tie 10 has round holes on both sides, and a first bolt 7 is installed in the round holes. A hexagonal nut 6 is rotatably installed on the other end of the first bolt 7. During operation, the external hose is connected to the slot on the top of the third valve body 3, and the metal cable tie 10 is installed at the slot and the outer wall of the hose. Through the cooperation of the first bolt 7 and the hexagonal nut 6, the hose is tightly connected to the third valve body 3. Through the above structure, different external pipes can be connected to the device, increasing the practicality of the device.
[0030] like Figures 3 to 4 and Figure 6As shown, the first valve body 1 has an annular groove at its bottom, the second valve body 2 has an annular groove at its top, and the third valve body 3 has an annular groove at its bottom. A first rubber ring 4 is installed between the grooves of the first valve body 1 and the third valve body 3. During operation, the high resilience of the rubber, combined with the hexagonal nut 6 and the first bolt 7, ensures a tight fit between the first valve body 1 and the third valve body 3, reducing the risk of leakage.

Through the above structure, the leak-proof performance of the device is improved, increasing the practicality of the device.
[0031] like Figures 1 to 2 As shown, a telescopic rod 14 is installed on the side wall of the third valve body 3. The telescopic rod 14 has two horizontal installations, and a fixing plate 15 is fixed to the other end of the telescopic rod 14. The fixing plate 15 has openings at both ends. During operation, the position of the third valve body 3 is adjusted by the telescopic rod 14, and the third valve body 3 is fixed by the fixing plate 15. Through the above structure, the device can be operated in a fixed position, which increases the stability of the device.
[0032] like Figures 1 to 4 As shown, a first rotating shaft 13 is installed at the other end of the motor 5, and the other end of the first rotating shaft 13 is fixed to the disc frame 12. During operation, by rotating the disc frame 12, the disc frame 12 drives the first rotating shaft 13, and the first rotating shaft 13 drives the internal components of the motor 5, so that the butterfly valve plate 8 can be controlled through the disc frame 12. Through the above structure, the device can be used without the use of electrical energy, increasing the practicality of the device.
[0033] like Figures 1 to 6 As shown, the first valve body 1, the second valve body 2, and the third valve body 3 are made of special materials. During operation, the first valve body 1, the second valve body 2, and the third valve body 3 are corrosion resistant and easy to clean. Through the above structure, the device obtains excellent corrosion resistance and can be used for a long time in harsh environments. At the same time, the surface is smooth and easy to clean, showing the device's beautiful appearance and practical performance.
[0034] During operation, motor 5 is started, and its output drives the second rotating shaft 16 to rotate. The second rotating shaft 16 then rotates the butterfly valve plate 8, opening the valve. Motor 5 is started again, and its output drives the second rotating shaft 16 to rotate, which in turn rotates the butterfly valve plate 8. Because the second rubber ring 9 is made of rubber, the outer wall of the butterfly valve plate 8 fits tightly against the inner wall of the second rubber ring 9 after rotation, closing the valve and preventing leakage. The rubber material of the second rubber ring 9 also reduces leakage at the connection gaps between the first valve body 1 and the second valve body 2.

The first bolt 7 and hexagonal nut 6 also work together to tightly connect the first valve body 1 at the bottom of the first valve body 1 and the third valve body 3.

The three valve bodies 3 are tightly fitted to the external pipeline. The external hose is connected to the slot on the top of the third valve body 3. The metal cable tie 10 is installed at the slot and the outer wall of the hose. The hose and the third valve body 3 are tightly connected by the cooperation of the first bolt 7 and the hexagonal nut 6. The high resilience of the rubber, together with the hexagonal nut 6 and the first bolt 7, makes the connection between the first valve body 1 and the third valve body 3 tight and reduces the risk of leakage. The high resilience of the rubber, together with the hexagonal nut 6 and the first bolt 7, makes the connection between the first valve body 1 and the second valve body 2 tight and reduces the risk of leakage. The position of the third valve body 3 is adjusted by the telescopic rod 14 and fixed by the fixing plate 15. By rotating the disc frame 12, the disc frame 12 drives the first rotating shaft 13. The first rotating shaft 13 drives the internal components of the motor 5, so that the butterfly valve plate 8 can be controlled by the disc frame 12. This improves the corrosion resistance and easy cleaning of the first valve body 1, the second valve body 2 and the third valve body 3.
