[0020] This utility model provides a gas mixing ratio regulating valve, including a mixing chamber 1, several inlet pipes 2, a mounting plate 3, an outlet pipe 4, a regulating gauge 5, and several regulating mechanisms. The regulating mechanism includes a sealing plate 6, an adjusting block 7, a connecting block 8, a connecting rod 9, a sliding rod 10, a spring 11, a protruding block 12, and four fixing components. The fixing components include bolts 13, nuts 14, and retaining rings 15. The aforementioned solution solves the problems of existing methods being not only cumbersome to operate, but also having mixing ratio accuracy easily affected by human factors.

[0021] In this specific embodiment, several intake pipes 2 communicate with the mixing chamber 1 and are located outside the mixing chamber 1. Several adjusting mechanisms are respectively disposed above the corresponding intake pipes 2. The sealing plate 6 is rotatably connected to the intake pipe 2 and is located inside the intake pipe 2. The adjusting block 7 is fixedly connected to the sealing plate 6 and is located above the sealing plate 6. The connecting block 8 is engaged with the adjusting block 7 and is located above the adjusting block 7. One end of the connecting rod 9 is fixedly connected to the connecting block 8, and the other end of the connecting rod 9 is slidably connected to the sliding rod 10 and is located above the adjusting block 7. One end of the spring 11 is fixedly connected to the sliding rod 10, and the other end of the spring 11 is fixedly connected to the sliding rod 10. The end is fixedly connected to the connecting rod 9 and located inside the sliding rod 10. The four fixing components are evenly arranged on the outside of the connecting block 8. In use, gas is introduced into the mixing chamber 1 through the air inlet pipe 2. According to the gas mixing ratio, the corresponding adjusting block 7 is controlled respectively. A motor 16 is provided above the sliding rod 10. The motor 16 moves the sliding rod 10 to rotate. The sliding rod 10 drives the connecting rod 9, so that the adjusting block 7 drives the sealing plate 6 to rotate accordingly. The sealing plate 6 can restrict the state of the air inlet pipe 2 to adjust the gas ratio accordingly. When disassembling, the connecting block 8 is pulled up, and the spring 11 contracts accordingly, pulling the connecting block 8 off the adjusting block 7.

[0022] The protrusion 12 is fixedly connected to the connecting block 8 and is located below the connecting block 8. The cross-section of the protrusion 12 is cross-shaped, and the protrusion 12 is engaged with the adjusting block 7. When the connecting block 8 rotates, the protrusion 12 drives the adjusting block 7 to rotate.

[0023] Secondly, the bolt 13 passes through the adjusting block 7 and the connecting block 8. The nut 14 is threadedly connected to the bolt 13 and is located below the adjusting block 7. One end of the retaining ring 15 is rotatably connected to the adjusting block 7, and the other end of the retaining ring 15 is fixedly connected to the nut 14 and is located on one side of the nut 14. By passing the bolt 13 through the adjusting block 7 and the connecting block 8 and fixing it with the nut 14, the adjusting block 7 and the connecting block 8 are tightly connected, which improves the stability of the adjusting block 7 and the connected block 8.

[0024] Secondly, the mounting plate 3 is positioned above the mixing chamber 1, and the adjustment table 5 is positioned above the mounting plate 3. The gas mixing ratio is displayed on the adjustment table 5. When the actual mixing ratio is different from the input mixing ratio, the corresponding motor 16 is adjusted accordingly, and the corresponding sealing plate is rotated accordingly to adjust the corresponding gas input.

[0025] In addition, the gas outlet pipe 4 is fixedly connected to the mixing chamber 1 and is located below the mixing chamber 1. The gas outlet pipe 4 discharges the mixed gas.

[0026] In use of this invention, gas is introduced into the mixing chamber 1 through the air inlet pipe 2. The corresponding adjusting blocks 7 are controlled according to the gas mixing ratio. A motor 16 is located above the sliding rod 10. The motor 16 rotates the sliding rod 10, which in turn drives the connecting rod 9, causing the adjusting blocks 7 to rotate the sealing plate 6 accordingly. The sealing plate 6 restricts the state of the air inlet pipe 2, thus adjusting the gas ratio. During disassembly, the connecting block 8 is pulled up, causing the spring 11 to contract, pulling the connecting block 8 off the adjusting block 7. The bolt 13 passes through the adjusting block 7 and the connecting block 8, and is secured by the nut 14, tightly connecting the adjusting block 7 and the connecting block 8, improving their stability. The gas mixing ratio is displayed on the adjustment table 5. When the actual mixing ratio differs from the input mixing ratio, the corresponding motor 16 is adjusted, causing the corresponding sealing plate to rotate, thus adjusting the corresponding gas input.
