Among them, the sealing method of the left blind plate 7 and the pilot valve body 8 adopts O-ring sealing; the left blind plate 7 and the right blind plate 9 are connected to the pilot valve body 8 through four studs 6 and locked by nuts at both ends; the left support column 3 and the right support column 10 are connected to the left blind plate 7 and the right blind plate 9 through threads; the hexagonal head bolt 5 and the U-shaped support frame 4 are also connected through threads; the pin I 2 and the pin II 11 are also connected to the U-shaped support frame 4 through threads; the water receiving trough 12 can be placed in the reserved groove under the main bracket 1, and there is no need to use a fastening method between the two; the left support column 3, the right support column 10, the stud 6, the left blind plate 7, the pilot valve body 8 and the right blind plate 9 together constitute the upper component; the left support column 3, the right support column 10 and the pin I 2 and the pin II 11 coordinate to form the upside-down flip structure of the upper component.

[0029] The specific working process of the present invention is as follows:

[0030] 1. First, lock the universal wheel 13 at the bottom of the main bracket 1 to ensure that it will not move during assembly, and place the water tank 12 in the reserved groove at the bottom of the main bracket 1.

[0031] 2. Then pass the four studs 6 through the left blind plate 7, the pilot valve body 8, and the right blind plate 9 in turn. After adjusting the position of the blind plate and the valve body, tighten the nuts at both ends of the studs to ensure that the valve body does not rotate. Pay attention to the coordination between the left and right blind plates and the valve body during assembly. Do not install the blind plates upside down. Then screw the left support column 3 and the right support column 10 into the threaded holes of the left blind plate 7 and the right blind plate 9 respectively.

[0032] 3. After completing the assembly of the upper component, lift the left and right support columns and place the entire upper component into the U-shaped groove of the U-shaped support frame 4. The fixing nuts of the left and right support columns must be ensured to be on the outside of the U-shaped support frame 4 to limit its axial displacement. Then screw the hexagon head bolt 5 into the threaded hole of the U-shaped support frame 4 to limit the radial displacement of the valve body.

[0033] 4. Finally, pass pin I 2 and pin II 11 through the threaded holes of the U-shaped support frame 4 into the blind holes on the left and right blind plates, tighten pin I 2 and pin II 11 to compress the upper assembly to ensure that it will not flip over, and assemble the components of the pilot valve in sequence.

[0034] 5. After the assembly of relevant parts on the upper end of the pilot valve body 8 is completed, loosen pin I2 and pin II 11, flip the upper assembly 180°, turn the lower end of the pilot valve body 8 upward, insert pin I2 and pin II 11 into the blind holes on the left and right blind plates and tighten them to realize the flipping function of the valve body, and then assemble the relevant parts to the lower end of the pilot valve body 8. After all the assembly is completed, loosen the locking device of the universal wheel 13 and push the installation test frame to the test site for relevant tests.
