The bottom of the sealing cap 6 is also fixedly connected to... The bottom end of the first sealing gasket 7 and the sealing cover 6 is fixedly connected to an insert plate 8, which has a slot 9. The connecting mechanism includes a fixed base 10, the top of which has a slot 11 that mates with the insert plate 8, and the side end of the fixed base 10 has a sliding groove 12. A sliding plate 13 is slidably disposed inside the sliding groove 12. The side end of the sliding plate 13 is fixedly connected to a locking plate 14 that matches the slot 9. The locking plate 14 slidably engages with the fixed base 10. The top end of the locking plate 14 has a bevel 23. When the insert plate 8 is inserted into the slot 11... The process facilitates the movement of the compression plate 14 towards the outside of the slot 11. A sealing plate 15 is installed on the side end of the fixed base 10 at the position corresponding to the slide groove 12. A second sealing gasket 22 is fixedly connected to the side end of the sealing plate 15 to ensure the sealing between the sealing plate 15 and the fixed base 10. A first compression spring 16 is provided between the sealing plate 15 and the slide plate 13. A strip groove 17 communicating with the slide groove 12 is provided at the bottom end of the fixed base 10. A push block 18 is slidably arranged inside the strip groove 17. The top of the push block 18 is flush with the bottom of the slide plate 13. The push block 18 is fixedly connected to the end. The bottom end of the push block 18 is equipped with a push seat 24 to facilitate the movement of the push block 18. A third sealing gasket 25 is provided between the top end of the push seat 24 and the fixed seat 10 to ensure the sealing between the push seat 24 and the third sealing gasket 25. The bottom end of the slot 11 is connected to two telescopic rods 19. The top end of the two telescopic rods 19 is fixedly connected to a top plate 20. The top plate 20 slides with the slot 11. A second compression spring 21 is sleeved on the outside of the two telescopic rods 19 to facilitate the upward movement of the insert plate 8 and the sealing cover 6.

[0033] Specifically, when not in use, the sealing cap 6 is placed over the protective tube 5 and fixed by the connecting mechanism. The first sealing gasket 7 ensures a tight seal between the sealing cap 6 and the protective tube 5, sealing the valve stem 2 and valve handle 3 inside the annular plate 4, the protective tube 5, and the sealing cap 6. This prevents the valve stem 2 and valve handle 3 from being exposed to the elements, avoiding corrosion and rust, and preventing the valve stem 2 from seizing up. It also facilitates the later rotation of the valve stem 2 and valve handle 3, allowing the insertion plate 8 to be inserted into the slot 1. After entering the interior, the first compression spring 16 pushes the card plate 14 into the card slot 9 to facilitate the fixing of the insert plate 8 and the sealing cover 6.

The handle 28 drives multiple sliding rods 26, valve handle 3 and valve stem 2 to rotate, thus making it easier for people to rotate the valve handle 3 and valve stem 2 and improving the effort-saving operation of the valve opening and closing.

[0036] In summary, when using the overall equipment:

[0037] When not in use, cover the protective tube 5 with the sealing cap 6, insert the multiple positioning pins 31 into the multiple positioning slots 30 respectively, and insert the two insert plates 8 into the two slots 11 respectively. Then press the sealing cap 6 down. As the insert plate 8 moves down, the side of the insert plate 8 contacts the inclined edge 23 of the card plate 14, squeezing the card plate 14 to the outside of the slot 11. After the sealing cap 6 presses the first sealing gasket 7, the card slot 9 and the card plate 14 are positioned accordingly. The first compression spring 16 pushes the slide plate 13 and the card plate 14 to move, so that the card plate 14 is inserted into the inside of the card slot 9, thus fixing the insert plate 8 and the sealing cap 6.

[0038] When it is necessary to remove the sealing cover 6, push the pusher 24. The pusher 24 drives the pusher 18, the slide plate 13 and the clamping plate 14 to move, so that the clamping plate 14 is separated from the clamping groove 9. After the clamping plate 14 is separated from the clamping groove 9, the top plate 20 is pushed upward by the two second compression springs 21. The top plate 20 pushes the insert plate 8 upward, so that the clamping groove 9 is moved to the upper side of the clamping plate 14. Then release the pusher 24 and then remove the sealing cover 6.
