The specific implementation mode is as follows:
go up the casing and pass through elevating gear flange 13 with lower casing and be connected, elevating gear's fire water intake is to outer the connection through fire water flange 17. The guide sealing integrated piece 15 is pressed between the upper shell and the lower shell, the lifting pipe penetrates through a through hole in the guide sealing integrated piece and can slide relative to the guide sealing integrated piece, and a first pressure water pipe opening is formed in the guide sealing integrated piece. An annular piston 12 is located within the upper housing 8, the annular piston 12 being secured in place by bolts 11 to the elevator tube annular boss 7-1 by an annular gland 10. The annular piston 12 divides an interlayer between the outer wall of the lifting pipe and the inner wall of the upper shell into a cavity I and a cavity II; when pressure is applied to the top of the annular piston 12, the piston 12 drives the elevator tube 7 to move downwards; when pressure is applied to the bottom of the annular piston 12, the piston 12 moves the elevator tube 7 upward.
Referring to fig. 1, a bottom flange 5 of an outdoor fire hydrant, which is commonly used at present, is connected and fixed with an upper flange 6 shown in fig. 3 in the specification. According to the attached figure 2 of the specification, a first hose 19-1 and a second hose 19-2 are respectively connected with a first water outlet Ps and a second water outlet P of a three-position four-way reversing valve 18 J The other end of the hose is connected with a first pressure water pipe port 9 and a second pressure water pipe port 14 of the lifting device. Wherein the water inlet P mouth and the fire water flange 17 of tribit four-way reversing valve connect same water source, promptly: fire-fighting water.
When fire occurs or the fire hydrant needs to be lifted, the handle 20 on the left side of the handle 20 of the three-position four-way reversing valve 18 is operated to rotate towards the right side, at the moment, the water inlet port P is communicated with the first water outlet port Ps, and meanwhile, the second water outlet port P is communicated with the first water outlet port Ps J The fire-fighting water enters the first cavity I below the piston 12 through the water inlet P, the first water outlet Ps, the first hose, the first pressure water pipe port and pushes the piston to drive the lifting pipe 7 and the fire hydrant connected with the lifting pipe to move upwards, so that the fire hydrant is lifted, and the fire hydrant is shown in the attached drawing 3 (in a lifting state). In the ascending process of the piston, water in the cavity II above the piston passes through the second pressure water pipe port, the second hose and the second water outlet P J The second outlet Ls is discharged in situ.
When the fire extinguishing task is completed or needs to be loweredWhen the fire hydrant is in use, the handle 20 of the right side descending of the three-position four-way reversing valve 18 is rotated to the left side, and at the moment, the water inlet P and the second water outlet P are connected J The ports are communicated with each other, and at the same time, the first water outlet Ps and the first water outlet L are communicated with each other J Communicated with each other, fire-fighting water passes through the water inlet P-the second water outlet P J The second hose-the second pressure water pipe-enters the II-th cavity above the piston 12, pushing the piston to move the elevator pipe 7 and the fire hydrant connected thereto downward, and lowering the fire hydrant, see fig. 2 (lowered state). Meanwhile, the water in the cavity I below the piston passes through a first pressure water pipe port, a first hose, a first water outlet Ps and a first water outlet L J The port is vented in situ. The elevator tube 7 is lowered into the interior space of the lower housing 16.
The operation handle 20 of the reversing valve 18 is rotated to the position shown in the attached figure 2, so that the pressurized water entering the upper cavity and the lower cavity of the piston can be closed, and the upper cavity II in the lower cavity I in the lifting device is prevented from being pressed for a long time.
Under the action of external rotation of the upper flange 6 and the fire hydrant 1 connected with the upper flange, the lifting pipe 7 overcomes each sealing ring
Or the resistance can realize rotation, so that the phenomenon that the fire fighting belt is broken and water is held back when fire fighting is carried out is avoided, and the fire fighting effect is influenced.
