[0027] The above structure achieves the following effects: when the petrochemical pipe 6 and the electric valve body 3 are connected, the first protective component 2, the second protective component 4 and the base plate 1 are used to form a closed protective cavity, which seals the connection at the bottom of the electric valve body 3, ensuring the safety of the valve connection. The pressure gauge 5 is used to monitor the protective cavity, thereby ensuring the stability and safety of the electric valve.

[0028] In this embodiment, the side wall of the electric valve body 3 is fixed with limit posts 31. There are four limit posts 31 in a rectangular distribution. The inside of the limit posts 31 is connected to a second fixing bolt 32. The outer wall of the second fixing bolt 32 is sleeved with a spring 33. The bottom ends of two second fixing bolts 32 are connected to the inside of the first protective component 2. The bottom ends of the other two second fixing bolts 32 are connected to the inside of the second protective component 4. The top surfaces of the first protective component 2 and the second protective component 4 are respectively fitted to the bottom surface of the limit posts 31.

[0029] By setting a limiting post 31 on the electric valve body 3, the top surfaces of the first protective component 2 and the second protective component 4 can be fitted and positioned, and then fixed by the second fixing bolt 32, which improves the stability of the connection between the first protective component 2, the second protective component 4 and the electric valve body 3, and ensures the sealing of the fit.

[0030] In this embodiment, the first protective component 2 includes a protective cover 21, a side sealing plate 22, a mounting plate 23, and a positioning bolt 24. A slot 211 is provided on one side of the top surface of the protective cover 21. The side wall of the electric valve body 3 fits into the inner wall of the slot 211. A side sealing plate 22 is fixed on one side of the protective cover 21. There are two side sealing plates 22 fixed in mirror image about the vertical center line of the protective cover 21. A mounting plate 23 is fixed on the outer wall of the protective cover 21. A positioning bolt 24 is connected through the inside of the mounting plate 23. A side baffle 12 is fixed on the side wall of the bottom plate 1. There are two side baffles 12 fixed about the vertical center line of the bottom plate 1.

The bottom surface of the side sealing plate 22 fits into the top surface of the side baffle 12. The bottom end of the positioning bolt 24 is connected to the inside of the bottom plate 1.

[0031] The protective cover 21 forms a protective cavity structure. During installation, the mounting plate 23 is slidably inserted between the two side baffles 12 and fixed to the base plate 1 by the positioning bolt 24 to ensure the overall sealing of the protective cavity.

[0032] In this embodiment, a sealing groove 212 is provided on the inner wall of the bottom of the protective cover 21, and a first sealing frame 13 is fixed on the top surface of the bottom plate 1. One side of the first sealing frame 13 is inserted into the sealing groove 212, and the adjacent side of the first sealing frame 13 is attached to the inner wall of the side sealing plate 22.

[0039] Working principle and usage process of this utility model:

[0040] First press Figures 1-5 The base plate 1 is installed at the location where the petrochemical pipe 6 passes by by the first fixing bolt 11. Then, the two petrochemical pipes 6 are passed through the two protective covers 21 respectively, and the petrochemical pipes 6 are connected to the two end interfaces at the bottom of the electric valve body 3, so that the electric valve is on the top of the base plate 1.

[0041] Then, two protective covers 21 are slid on the petrochemical pipe 6, so that the mounting plate 23 is attached to the base plate 1. The two sides of the mounting plate 23 are attached to the side baffle 12 and slide. The bottom surface of the side sealing plate 22 is attached to the top surface of the side baffle 12 and slides. The inner wall of the side sealing plate 22 is attached to the outer wall of the first sealing frame 13 and slides. So that the protective cover 21 is inserted between the bottom surface of the limiting post 31 and the top surface of the second sealing frame 34 until the side wall of the electric valve body 3 is inserted and attached to the inside of the slot 211. At the same time, the first sealing frame 13 is inserted into the sealing groove 212 of the protective cover 21 and sealed. So that the connection between the bottom of the electric valve body 3 and the petrochemical pipe 6 is sealed inside the protective cavity formed by the cooperation of the protective cover 21.

[0042] Finally, the second fixing bolt 32 is rotated and connected through the limit post 31, the protective cover 21 and the second sealing frame 34. The rotating positioning bolt 24 is connected to the base plate 1 for positioning and fixing, ensuring the overall structure is stable and sealed. When the staff is inspecting, they only need to open the protective cover 21 to operate. Before opening, they can check the data of the pressure gauge 5 to confirm the internal leakage before carrying out safe maintenance operations.
