Abstract
The utility model belongs to a rubber-pipe adaptor for high-pressure exploratory boring for oil drilling and exploitation industry. An inner liner (7) is arranged between inner layer rubber (8) and a steel wire layer (9); a huff sleeve (5) is arranged out of the steel wire layer; adhesives are filled between the inner liner and the steel wire layer, and between the steel wire layer and the huff sleeve. The utility model has simple and reasonable structure, and adopts the method of double connection of the mechanical buckling and the adhesives so that the anchoring effect is good; the looseness phenomenon can not happen; specially under the condition of high-pressure pulse, compared with the simple mechanical buckling type, the utility model is safer, and the service life is longer.
Description
The utility model belongs to oil drilling and extraction industry high pressure drilling hose joint.
At present, drill hose is mainly used in the industries such as oil drilling, underground work, harbour oil transportation, hydraulic coal mining and carries high pressure water, air, oil and oil-base mud etc., rubber hose coupling there is strict requirement, and the connecting mode of sebific duct and joint is simple mechanical combined type such as Ka Fanshi, accurate Ka Fanshi, binding type etc., and the steel wire floor of joint and sebific duct and internal layer rubber snap together.Because rubber has creep properties, As time goes on, the rubber layer of sebific duct changes, and the fastening dynamics of joint and sebific duct body dies down, and joint easily comes off, and working life is short, and it is unreliable to work.
The purpose of this utility model can be eliminated above-mentioned shortcoming in order to provide a kind of exactly, adopts machinery to fasten and the tackiness agent bonding mode between joint and sebific duct, and in conjunction with firm, and joint length is short, lightweight high pressure drilling hose joint.
In order to achieve the above object, the utility model is provided with neck bush (7) between internal layer rubber (8) and steel wire floor (9), and steel wire floor has Hough cover (5) outward, between neck bush and steel wire floor, steel wire floor and Hough inner room fill tackiness agent.
Connect by silk ring (4) between the neck bush of this device (7) and Hough cover (5), outer being provided with of Hough cover tightens cover (6), tighten to justify in the cover and have and the identical tapering of Hough cover cylindrical, be pressed into expanding sheath (3) in sebific duct (10) pore, there is the conical surface greater than the sebific duct pore outer end of expanding sheath, fastens nut (2) and connects with the Hough cover, and socket (1) is abutted against on the exterior edge face of sebific duct (10), the number of plies of steel wire floor (9) is 2 layers or 4 layers, and each interlayer fills tackiness agent.
The utility model is simple and reasonable, adopts machinery to fasten and the bonding dual connecting mode of tackiness agent, and is fastening effective, and the non-loosening phenomenon is under the high-voltage pulse situation, more safer than simple mechanical snap-together type especially, longer service life.
Be described further below in conjunction with accompanying drawing:
Description of drawings: figure is the device sectional view.
The sequence number of each parts is respectively among the figure: socket (1) fastens nut (2); Expanding sheath (3), silk ring (4), Hough cover (5) tightens cover (6), neck bush (7), internal layer rubber (8), steel wire floor (9), sebific duct (10).
This device is provided with neck bush (7) between internal layer rubber (3) and steel wire floor (9), the material of neck bush is preferably iron or steel or engineering plastics, the outer Hough cover (5) that is provided with of steel wire floor (9), the interior circle of the cylindrical of neck bush and Hough cover is provided with screw thread, by silk ring (4) neck bush and Hough cover are connected into one, between neck bush and steel wire floor (9), steel wire floor and Hough inner room fill tackiness agent, the number of plies of steel wire floor is 2 layers or 4 layers, fills tackiness agent between each steel wire.
Outer being provided with of the Hough cover (5) of this device tightens cover (6), and the interior circle that tightens cover has and the identical tapering of Hough cover cylindrical, and the little end in awl footpath is connected into one by steel wire and sebific duct (10), rotates the Hough cover and can make its fastening steel wire floor (9).
The sebific duct of this device (10) pore end is provided with expanding sheath (3), there is the conical surface greater than the sebific duct pore outer end of expanding sheath, stretch out the outer part of sebific duct and withstood by socket (1), socket is withheld on the sebific duct exterior edge face by fastening nut (2), fastens nut and Hough cover (5) scyewed joint.
The Hough cover (5) of this device is withheld on steel wire floor (9), owing to tighten the effect of cover (6) and neck bush (7), fastens great efforts, indeformablely do not come off, the expanding sheath (3) that is provided with has not only strengthened the intensity of sebific duct (10) tube wall, and has increased the sealing of joint, joint ne-leakage.
Claims (4)
1, a kind of high pressure drilling hose joint, comprise sebific duct (10), steel wire floor (9), internal layer rubber (8), socket (1), it is characterized in that being provided with neck bush (7) between internal layer rubber (8) and steel wire floor (9), steel wire floor (9) is outer Hough cover (5), between neck bush (7) and steel wire floor (9), steel wire floor and the filled tackiness agent of Hough inner room.
2, high pressure drilling hose joint according to claim 1 is characterized in that outer being provided with of said Hough cover (5) tightens cover (6), tightens that circle has and the identical tapering of Hough cover cylindrical in the cover, Hough overlap with neck bush (7) between connect by silk ring (4).
3, high pressure drilling hose joint according to claim 1, the steel wire number of plies that it is characterized in that said steel wire floor (9) are 2 layers or 4 layers, and each interlayer fills tackiness agent.
4, high pressure drilling hose joint according to claim 1 is characterized in that in described sebific duct (10) pore expanding sheath (3) being arranged, and the expanding sheath outer end has the conical surface greater than the sebific duct pore.
