As preferably, vertical lifting pipe lateral surface is not arranged over fall way limited block with the most fixing pipe, and fall way limited block is positioned at below fire coupling.
As preferably, spool is coaxial with vertical lifting pipe.
As preferably, discharge outlet is provided with drain pipe, and drainage switch valve is arranged on drain pipe.
As preferably, vertical lifting pipe is coaxially disposed with the most fixing pipe.
The beneficial effects of the utility model are: have and can install fire hose, feature easy to use on the ground.
Accompanying drawing explanation
Fig. 1 is the underground hydrant of the present utility model a kind of structural representation in actual application.
In figure: vertical lifting pipe 1, fall way limited block 2, fire coupling 3, first piston 4, spool 5, the first guide pin bushing 6, first guide rod 7, drainage switch valve 8, drain pipe 9, first guide rod limited block 10, discharge outlet 11, dodge through hole 12, the most fixing pipe 13, water inlet 14, water inlet switch valve 15, water inlet pipe 16.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, a kind of underground hydrant include upper and lower closed at both ends vertically fixing pipe 13, can along the first piston 4 that the most fixing pipe slides, be arranged on the most fixing pipe in and the vertical lifting pipe 1 that is connected with first piston and be arranged on the self adaptation mechanism for opening/closing in the most fixing pipe.The upper end of the most fixing pipe is provided with dodges through hole 12.Vertical lifting pipe is coaxially disposed with the most fixing pipe.
The upper end of vertical lifting pipe is through dodging through hole and being positioned at above the most fixing pipe.The upper end closed of vertical lifting pipe.On vertical lifting pipe and be positioned at vertically fixing pipe and be arranged over fire coupling 3, the number of the fire coupling of the present embodiment is one.The lower end of vertical lifting pipe is down through first piston, and the lower ending opening of vertical lifting pipe.Vertical lifting pipe is sealedly and fixedly connected with first piston.It is not arranged over fall way limited block 2 with the most fixing pipe on vertical lifting pipe lateral surface, and fall way limited block is positioned at below fire coupling.
Self adaptation mechanism for opening/closing includes being arranged on vertically fixing manages interior and is positioned at the first guide pin bushing 6 below vertical lifting pipe, is slidably arranged on the first guide rod 7 of the first guide pin bushing and is arranged on the first guide rod the spool 5 for controlling vertical lifting pipe on/off.First guide pin bushing is connected with the most fixing pipe by head rod.Spool is positioned at the top of the first guide pin bushing.On first guide rod lateral surface and be positioned at below the first guide pin bushing and be provided with the first guide rod limited block 10.Spool is coaxial with vertical lifting pipe.Spool can be moved to vertical lifting pipe by the lower port of vertical lifting pipe.Vertically fix on pipe lateral surface and be positioned at below the first guide pin bushing and be provided with water inlet 14 and discharge outlet 11.Water inlet is provided with water inlet switch valve 15.Discharge outlet is provided with drain pipe 9.Discharge outlet is provided with drainage switch valve 8, and specifically, drainage switch valve is arranged on drain pipe.
As it is shown in figure 1, when fall way limited block is resisted against the outer end face of the most fixing pipe, spool is positioned at vertical lifting pipe and blocks the lower port of vertical lifting pipe.
When first piston is resisted against the inner top surface of the most fixing pipe, spool is positioned at the lower section of vertical lifting pipe.
The specifically used process of the underground hydrant of the present embodiment is as follows:
As it is shown in figure 1, underground hydrant is installed to underground, the import of water inlet pipe 16 with water inlet switch valve is connected.
During use: fire fighter is by water inlet switch valve opening, water in water inlet pipe enters in the most fixing pipe, then, vertical lifting pipe is driven to rise by first piston under hydraulic pressure effect, during vertical lifting pipe rises, when moving to above earth's surface on fire coupling, fire fighter just can start to install fire hose on the ground, is docked with fire coupling rapidly by fire hose coupling before spool separates with vertical lifting pipe.
On the other hand, during vertical lifting pipe rises, also band movable valve plug and the first guide rod together being risen, when the first guide rod limited block is resisted against on the first guide pin bushing, spool and the first guide rod stop rising；And first piston also will drive vertical lifting pipe to continue to rise, till first piston is resisted against the inner top surface of the most fixing pipe, now spool is positioned at the lower section of vertical lifting pipe.When spool is positioned at the lower section of vertical lifting pipe, the water in the most fixing pipe by entrance vertical lifting pipe and is entered fire hose by fire coupling；Thus the underground hydrant of the present invention has only to open this valve of water inlet switch valve when actually used, just can realize vertical lifting pipe to rise, facilitate fire fighter that fire hose (need not extra power-equipment) is installed on the ground, and automatically supply water for fire hose within following a period of time.
After underground hydrant has used, close water inlet switch valve, opening water discharge controlled valve；Then, the pressure of vertical lifting pipe being resetted, be resisted against until fall way limited block till vertically fixing on the outer end face of pipe, now, spool is positioned at vertical lifting pipe and blocks the lower port of vertical lifting pipe；Followed by, close drainage switch valve.
