Figure.
Referring to Fig.1-3, the utility model proposes a kind of interior fire supply pipeline emptier, including wall 1, into
Water pipe 2, valve 3, connecting tube 4, three-way connection 5, fire water-supply pipe 6, evacuated tube 7, angle coupling 8, drainpipe 9, emptying seat 11,
Block 12, screw rod 14, spring 15 and nut 16；
2 one end of water inlet pipe is connected on water system pipes, and the other end protrudes into interior across wall 1 and is connected with valve 3；
Valve 3 is connected by connecting tube 4 with three-way connection 5；5 liang of three-way connection outlet respectively with 7 phase of fire water-supply pipe 6 and evacuated tube
Even；Fire water-supply pipe 6 is arranged upward；Evacuated tube 7 is arranged downward, and placing groove 71 is provided in evacuated tube 7；The setting of seat 11 is emptied to exist
On placing groove 71, emptying seat 11 is the round tube that one end blocks, and emptying seat 11 blocks end and is provided with the through-hole 112 passed through for screw rod 14
With the drainage hole 113 for draining；The setting of through-hole 112 blocks end center in emptying seat 11；14 lower end of screw rod passes through through-hole
112 are connected with nut 16, and 14 upper end of screw rod is connected with link block 13；Block 12 is arranged on link block 13, and 12 diameter of block is small
In placing groove 71 diameter and be greater than emptying seat 11 internal diameter；The setting of spring 15 in 14 periphery of screw rod, 15 both ends of spring respectively with
Link block 13 is connected with emptying seat 11；
9 one end of drainpipe is connected by angle coupling 8 with evacuated tube 7, and 9 other end of drainpipe passes through wall 1 and reaches room
Outside.
In a kind of specific work process of the emptier of interior fire supply pipeline of the present embodiment, when fire-fighting needs to use
When water, valve 3 is opened, fire demand water is entered in three-way connection 5 by water inlet pipe 2 in water system, since intake pressure is larger,
Hydraulic pressure compresses spring 15, and block 12 seals emptying seat 11, and water flow is discharged from fire water-supply pipe 6, and supply fire-fighting uses, when not
When needing with water, valve 3 is closed, evacuated tube 7 is interior without high-strength hydraulic pressure, and the reset of spring 15 jacks up block 12, and water flow passes through emptying
The drainage hole 113 that 11 bottoms of seat are equipped with is discharged, and interior is discharged via drainpipe 9.Present apparatus structure is simple, can automatic fast evacuation
Water in fire water-supply pipeline, the case where preventing frozen pipe generation avoid influencing being normally carried out for fire-fighting work.
In a specific embodiment, frost retarding layer 10 is equipped with outside evacuated tube 7, angle coupling 8 and drainpipe 9.When temperature compared with
When low, icing phenomenon, which can occur, for water when evacuated tube 7 is drained, in pipe leads to frozen pipe, influences the progress of fire-fighting work, frost retarding layer
10 setting ensures that evacuated tube will not protect pipeline equipment because of low temperature frozen pipe.
Further, 12 upper end of block is arc surface.Block 12 is used for the opening and closing of emptying equipment, when being emptied
When, 12 upper end of block is that arc surface ensures all drained noresidues of the water energy in pipe, prevents from leading to frozen pipe because of residual.
In work, emptying 11 periphery of seat is equipped with multiple annular grooves 111, is provided with sealing ring 17 in annular groove 111.It is close
The setting of seal 17 ensures to empty the leakproofness that seat 11 is contacted with evacuated tube 7, prevents because there are the feelings that gap leads to leak for contact
Condition occurs.
Further, drainage hole 113 is provided with multiple and is distributed with through-hole 112 for center circumference array.Drainage hole 113 is used
In water remaining in emptying fire water-supply pipe 6, drainage hole 113 is provided with multiple and is distributed with through-hole 112 for center circumference array,
Ensure that water energy remaining in fire water-supply pipe is quick, whole discharges of noresidue avoid leading to frozen pipe because of residual.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
