The front portion of 31.
The hydraulic balance hole 34 that back-up ring 10 is penetrating before and after being provided with.
The work process of urban discharging pipeline dredging system is as follows: the main adpting flange 5 on main water inlet tube 4 and auxiliary water supply
Auxiliary adpting flange 15 on pipe 12, is all connected with high-pressure water (high-pressure water can use the dredging vehicle that municipal works are commonly used),
Being placed into by this utility model at the blocking of drainage pipeline, open main control valve 6, water under high pressure is entered into main company by main water inlet tube 4
In adapter 2 and Dredge drill bit, water under high pressure drives back-up ring 10, pressure bearing 11 and high-pressure hose 7 to move forward, and Dredge drill bit is anterior
Conical structure limit the position that moves forward of pressure bearing 11, now the outer ring of pressure bearing 11 is retreating hole for water spraying 17 envelope
Stifled, meanwhile, water under high pressure sprays in advance hole for water spraying 16 backward, owing to the centrage of advance hole for water spraying 16 deviates Dredge drill bit
Centrage, i.e. due to advance hole for water spraying 16 arranged off-centre, under the jet-action of water under high pressure, the momentum that injection produces makes dredging drill
Head rotates, and axially produces active force forward, and owing to Dredge drill bit is provided with spiral helicine fin bar 1, fin bar 1 is also with dredging
Logical bit produces spiral thrust to Dredge drill bit, at spiral thrust and water flowing common action, promotes Dredge drill bit to rotate
Also travelling forward simultaneously, thus dredge tamper in drainage pipeline, tamper is also played good dredging by water under high pressure
Effect.
Owing to drainage pipeline is long, it is difficult to after Dredge drill bit precession directly exit, at this moment closes main control valve 6, beat
Opening aux. control valve 14, water under high pressure is entered into high-pressure hose 7 by auxiliary water-feeding tube 12, enters finally in Dredge drill bit, high pressure
Water-driven back-up ring 10 and pressure bearing 11 are moved rearwards by, and make high-pressure hose 7 bend, and pressure bearing 11 is limited by adapter sleeve 31 rear portion
The position being moved rearwards by, now the outer ring of pressure bearing 11 blocks advance hole for water spraying 16, and meanwhile, water under high pressure is from retreating hole for water spraying
Spray backward in 17, owing to retreating the centrage of the centrage deviation Dredge drill bit of hole for water spraying 17, i.e. owing to retreating hole for water spraying 17
Arranged off-centre, under the jet-action of water under high pressure, the momentum that injection produces makes Dredge drill bit rotate, and axially produces effect backward
Power, owing to Dredge drill bit is provided with spiral helicine fin bar 1, fin bar 1 rotates also with Dredge drill bit and produces Dredge drill bit
Spiral thrust, at spiral thrust and water flowing common action, also rearward movement while promoting Dredge drill bit to rotate, thus make to dredge
Logical drill bit exits drainage pipeline.
Due to the setting of rotating seal 3, Dredge drill bit drives main connecting tube 2 to rotate when rotating, main water inlet tube 4, front
Sleeve 18 and rear sleeve 19 all maintain static, and advance along with Dredge drill bit or retreat, the deep groove ball bearing 25 in rotating seal 3
Playing the effect that main connecting tube 2 well rotates, front sealing ring 27, rear sealing ring 28 and main water inlet sealing ring 29 play and avoid leaking
Effect.The front limit ring 9 arranged on high-pressure hose 7 and rear spacing ring 8, can be located at fixing for back-up ring 10 on high-pressure hose 7, keep away
Exempting from back-up ring 10 and pressure bearing 11 and depart from high-pressure hose 7 under the effect of water under high pressure, high-pressure hose 7 is along with back-up ring 10 and pressure axis
Before and after holding 11, movement can stretch or bend.
The hydraulic balance hole 34 arranged on back-up ring 10, water under high pressure can make back-up ring 10 and pressure bearing by hydraulic balance hole 34
Before and after 11, the pressure of both sides keeps balance, it is to avoid hydraulic pressure is excessive to be produced huge axial force to back-up ring 10 and pressure bearing 11 and make
Pressure bearing 11 departs from back-up ring 10 or makes the outer ring of pressure bearing 11 depart from inner ring.
Dredge drill bit is made up of drill body 30 and adapter sleeve 31, is so not only convenient for manufacturing, and is easily installed,
It is easily attached the assembly connection between set 31 and main connecting tube 2.
(centrage eccentric setting, such as the deviation distance in Fig. 2 for the structure that arranges of advance hole for water spraying 16 and retrogressing hole for water spraying 17
X, the inner port of advance hole for water spraying 16 is positioned at the front side of the external port of advance hole for water spraying 16, retreat hole for water spraying 17 inner port position
In the rear side of the external port retreating hole for water spraying 17, the centrage of the centrage of advance hole for water spraying 16 and retrogressing hole for water spraying 17 is all with thin
The centrage of logical drill bit is the angle of 40-50 °, preferably 44 °), water under high pressure so can be made to drive Dredge drill bit to rotate the most fully
Reduce resistance.
Shape of the present utility model, material, structure etc. are not made any pro forma restriction, every foundation by the present embodiment
Any simple modification, equivalent variations and the modification that above example is made by technical spirit of the present utility model, belongs to this reality
Protection domain by new technique scheme.
