The many cutterheads of quantity, but the cutter head center region belongs to enclosed construction, dregs does not have relative motion in central area, holds
Easy mud lining.
Therefore, the sediment improvement means for strengthening cutter head center region just have to solve the problems, such as into one.
The content of the invention
For above-mentioned deficiency described in the prior, the invention provides can quick flush improved knife central area
Dregs, the dregs molding in cutter head center is prevented, it is economic and practical, the Central Closed formula cutter head center of operating efficiency can be effectively improved
Flushometer.
To realize above-mentioned technical purpose, the technical solution adopted in the present invention is as follows：
A kind of Central Closed formula cutter head center flushometer, including small swivel coupling, big swivel coupling, transition piece, cutterhead
Flange and spout, small swivel coupling are arranged on big swivel coupling and are connected in series with big swivel coupling, and big swivel coupling is fixed
On transition piece, transition piece is fixed on cutterhead flange, and spout is arranged on cutterhead flange, the passage I of small swivel coupling with it is big
The passage II of swivel coupling is docked, and passage II is docked with the passage III on transition piece, and passage III is connected with spout.
The spout includes spout I and spout II, and spout I and spout II are arranged on cutterhead flange, and the passage III divides
For two-way, it is connected all the way with spout I, another way is connected by pipeline with spout II.
The spout I includes body I, and body I is arranged in the mounting hole I of cutterhead flange, rear end and the passage III of body I
Connection all the way, the front end of body I is provided with unidirectional valve rubber.The check configuration of spout I can effectively prevent dregs from entering spout I
Inside result in blockage, influence sediment improvement effect.
The spout II includes body II, and body II is removably mounted in the mounting hole II of cutterhead flange, body II
Top be connected by pipeline with the another way of passage III, the front end of body II is provided with unidirectional valve rubber, the rear end of body II
Globe valve is installed.The check configuration of spout II can effectively prevent dregs from entering in spout II to result in blockage, and influence sediment improvement
Effect.And can be dredged after the blocking of spout II by globe valve, spout II is removably mounted on cutterhead flange, when
Spout II can be split out and be changed by the unidirectional valve rubber of the front end of spout II after thoroughly damaging.
The present invention is connected in series by small swivel coupling and big swivel coupling, and the passage I of small swivel coupling connects with big revolution
The passage II of head is docked, and passage II is docked with the passage III on transition piece, and passage III is connected with spout.Water source is from small swivel coupling
Import enter, sprayed by passage I, passage II and passage III from spout I and spout II, to the slag in closed cutter head center
Soil is improved, and effectively prevents dregs molding, improves operating efficiency, and the present invention is overall with cutterhead flange rotary, Bu Huizao
Wound into pipeline, reduce rate of breakdown, and the present invention is easy to use, makes simply, using effect is good.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of spout II of the present invention.
Embodiment
As shown in Figure 1-2, a kind of Central Closed formula cutter head center flushometer, including small swivel coupling 1, big swivel coupling
2nd, transition piece 3, cutterhead flange 4 and spout, small swivel coupling 1 be arranged on big swivel coupling 2 on and with the big company of series connection of swivel coupling 2
Connecing, big swivel coupling 2 is fixed on transition piece 3, and transition piece 3 is fixed on cutterhead flange 4, and spout is arranged on cutterhead flange 4,
The 1-1 of passage I of small swivel coupling 1 docks with the 2-1 of passage II of big swivel coupling 2, the 2-1 of passage II and the passage on transition piece 3
III 3-1 is docked, and the 3-1 of passage III is connected with spout.
In the present embodiment, the spout includes spout I 5 and spout II 6, and spout I 5 and spout II 6 are arranged on cutterhead method
On orchid 4, the 3-1 of passage III points are two-way, are connected all the way with spout I 5, another way is connected by pipeline with spout II 6.
Specifically, the spout I 5 includes body I, and body I is arranged in the mounting hole I of cutterhead flange 4, after body I
End is connected all the way with the 3-1's of passage III, and the front end of body I is provided with unidirectional valve rubber.The check configuration of spout I 5 can effectively prevent
Only dregs enters in spout I 5 and resulted in blockage, and influences sediment improvement effect.
The spout II 6 includes body II, and body II is removably mounted in the mounting hole II of cutterhead flange 4, body
II top is connected by pipeline with the 3-1 of passage III another way, and the front end of body II is provided with unidirectional valve rubber, body II
Rear end is provided with globe valve 6-1.The check configuration of spout II 6 can effectively prevent dregs from entering in spout II 6 to result in blockage, and influence
Sediment improvement effect.And can be dredged after the blocking of spout II 6 by globe valve, spout II 6 is removably mounted on knife
In reel flanges, spout II 6 can be split out and be changed after the unidirectional valve rubber of the front end of spout II 6 thoroughly damages.
Operation principle：Water under high pressure is connected to the import of small swivel coupling 1 by pipeline, and water under high pressure is by the 1-1 of passage I and leads to
The 2-1 of road II enters transition piece 3, and is sprayed by the 3-1 of passage III on transition piece 3 from the spout I 5 on cutterhead flange 4 and spout II 6
Go out, the dregs of improved knife central area, reduce incrusted probability；The pipeline of water under high pressure cannot connect directly to cutterhead flange
On spout because cutterhead flange is a rotating mechanism, if the pipeline of water under high pressure is connected on cutterhead flange, work as cutterhead
The pipeline of water under high pressure can be twisted into twisted shape during flange rotary.The globe valve 6-1 of the rear end of spout II 6 is closed when flat,
Once occur spout II 6 block situation, can by globe valve 6-1 dredge spout II 6, and spout II 6 be designed as it is removable
Go out formula, after the unidirectional valve rubber of the front end of spout II 6 thoroughly damages, spout II 6 can be split out replacing.
