[0027] The PVDF plastic air conditioning valve body 1 and valve cover seat 2 are internally fitted with two symmetrically arranged limiting pins 11. Through the installation and use of the U-shaped positioning seat 10 and the limiting pins 11, their interlocking securely positions the PVDF plastic air conditioning valve, improving its stability and preventing shaking. This ensures the air conditioning valve functions properly and the air conditioning system operates stably. One side of the double-ended screw 7 passes through the U-shaped base 6 and extends to another side of the U-shaped base 6. A handwheel 9 is fixedly installed on one side of the double-ended screw 7. Two round rods 12 are fixedly connected to the inner side of the U-shaped base 6. The outer surfaces of the two round rods 12 are flush with the interior of the threaded plate 8.

[0029] One side of the limiting slide rod 24 passes through the rotating plate 23 and extends to the other side of the rotating plate 23. A disc 25 is fixedly installed on one side of each of the two limiting slide rods 24. A threaded hole 88 is opened on one side of the rotating plate 19. The threaded hole 88 is adapted to the bolt 27. The outer surface of the bolt 27 is threadedly connected to one side of the rotating plate 19 through the threaded hole 88.
[0030] The interior of each of the two U-shaped positioning seats 10 is provided with two through slots 77, which are adapted to the limiting pins 11. The outer surface of the limiting pins 11 is engaged with the interior of the U-shaped positioning seats 10 through the slots 77.
[0031] The working principle of the PVDF plastic air conditioning valve provided by this utility model is as follows:
[0032] By turning bolt 27, bolt 27 can be turned out from the threaded hole 88 of the rotating plate 19 to release the limit on the protective cover 20. Then, the rotating plate 19 at the U-shaped plate 18 can drive the protective cover 20 to rotate downward. At this time, the protective cover 20 can protect the metal plate of the PVDF plastic air conditioning valve. Next, pull the disc 25 to compress the limiting slide rod 24 with the connecting spring 26 installed. Then rotate the rotating plate 23, which can drive the elastic limiting slide rod 24 to rotate to the side plate 21. In this way, the two limiting slide rods 24 can be engaged in the embedded grooves 66 of the two side plates 21 to secure the protective cover 20. In this way, the protective cover 20 can stably and reliably perform protective work, avoiding damage to the metal plate of the PVDF plastic air conditioning valve, thereby extending the service life of the PVDF plastic air conditioning valve.
[0033] The PVDF plastic air conditioning valve body 1 and valve cover seat 2 can be fixed by using the reinforcing bolt 3. Then, turn the handwheel 9, which will drive the double-ended screw 7 to rotate. This allows the two threaded plates 8 on the double-ended screw 7 to move towards each other, so that the U-shaped positioning seats 10 at the two threaded plates 8 can be engaged with the two ends of the PVDF plastic air conditioning valve body 1 and valve cover seat 2. Then, insert the two limiting pins 11 into the slots 77 of the two U-shaped positioning seats 10 to reinforce the installation of the PVDF plastic air conditioning valve. Next, tighten the two bolts 14 to fix the bolts 14 to the bottom of the limiting pins 11. At the same time, the fixing seats 16 at the two fixing plates 15 can also limit the valve cover seat 2, making the entire PVDF plastic air conditioning valve more stable and reliable, reducing the occurrence of failures due to component shaking or displacement.
