Description
Technical field
This patent is related to oil and gas exploitation and transmission engineering technical field, specifically a kind of impermeable nonmetallic
Flexible compound hose fast connecting joint.
Background technology
Along with society continuous development and China's energy supply and demand is contradictory becomes increasingly conspicuous, the demand of petroleum resources
It is constantly being promoted, this also indirectly pushes oil-gas mining and the development of transmission technology and innovation.It is poor, raw with traditional corrosion-resistant
Metal pipe line of high cost is produced to compare, nonmetal flexible composite soft tube be one kind made of polymer composite have it is higher
Intensity, the excellent properties such as high pressure, corrosion-resistant, resistance to fouling, the coefficient of friction resistance be small, good heat preservation performance, the good, long lifespan of flexibility stone
Oily gas industry conveying pipe fitting.Up to now, nonmetal flexible composite soft tube is in Xinjiang（The Takla Makan Desert）, it is long
The oil gas fields such as celebrating, grand celebration, Jilin, huge port, North China are widely applied, mainly individual well oil-gas gathering and transportation, acidification,
Pressure break, waste water injection, individual well water filling/note alcohol etc., application effect is good.
The structure of nonmetal flexible composite soft tube is mainly made of tube core, enhancement layer, surrounding layer from inside to outside, core
Pipe is mainly based on the poly- record ethylene tube after crosslinked with silicane high density polyethylene pipe and nanometer improvement.Strengthening layer is mainly
Based on braiding on tube core and the reinforcing fiber silk and steel wire rope that wind, carried out using year bonding agent between reinforcing fiber layer
Adhesion.Surrounding layer mainly based on polyethylene anticorrosion material, has higher anticorrosive property function.
The general 10MPa of nonmetal flexible composite soft tube operating pressure or so, internal diameter 100-200mm for petroleum industry,
Wall thickness is generally 10mm or so, and buried depth of pipeline is generally 1m or so.In addition, in the production process of hose, by equipment load-bearing energy
The limitation of power and space size, a hose are unlikely to be totally continuous, and every 500~1000m will have a rigidity
Connector, that is, be rigidly connected connector.The connection type of nonmetal flexible compound pipeline complex pipeline is mainly with screw thread type, attaching type, flange
It is with screw thread type under normal circumstances according to actual pressure rating difference using targetedly connection type based on formula, union formula
Connection type based on.
However, the nonmetallic relationship for oil and gas industry conveying is generally up to tens of kms, even as high as 100 kms, need
Tens of nonmetal flexible composite soft tubes are attached, and existing connector needs bulky tool not only during the connection process
The case where efficiency is low, and in flexible hose pipeline actual moving process, and joint area is easy to happen infiltration.In addition,
Desert area annual March to October is desert season, and air quantity is bigger, and sand dune can largely migrate, and average speed is up to 6m/
Year, the migration of sand drift causes pipeline vacantly on sandy soil, causes nonmetal flexible composite pipe body and connector tension and occur
It destroys.In this regard, needing to migrate flexible duct and repaired, the paving location of pipeline is controlled as possible in the position far from air port
It sets, frequent butt joint is needed to be dismantled, installed and replaced in migration and maintenance process, if connect using existing
Head not only migrates, significant decrease oilfield economic efficiency low with maintenance efficiency, and is easy to cause connector and is damaged, to the fortune in later stage
Row constitutes security risk.
For this purpose, the present invention proposes a kind of impermeable nonmetal flexible composite soft tube jointing, what which used pulls
Hand formula disassembly and installation method is remarkably improved the construction efficiency of nonmetal flexible composite soft tube, the ball of the metal-metal of use
Sealing structure and shoulder sealing structure in face of the conical surface can effectively prevent CO2、CH4、H2The infiltration of all kinds of gases such as S, use
Non-threaded corrosion resistant alloy sealing structure cannot be only used for all kinds of corrosive mediums, and can effectively prevent from generating because of screw thread close
Envelope problem, to ensure that flexible nonmetallic tubing is in a safe condition always under harsh running environment.
Invention content
The object of the present invention is to provide a kind of impermeable nonmetal flexible composite soft tube fast connecting joints, to solve sand
The technical barrier that nonmetal flexible composite soft tube safely and fast connects in the corrosive mediums transmission process such as unconcerned oil gas water, the device is not
It is only simple in structure, easy to operate, and easily meet the practical military service operating mode that composite soft tube faces.
To achieve the above object, the present invention takes following technical scheme：
The present invention proposes a kind of impermeable nonmetallic composite soft tube fast connecting joint, includes mainly：It is special pin end, tight
Detain shoulder, female coupling tap screw thread, die nipple screw thread, sealing cone, special female connector, protection shoulder, sealing spherical surface, hex bolts, wherein
The material of special pin end and special female connector is corrosion resistant alloy, and the hex bolts with female coupling tap screw thread is by ordinary carbon steel material system
At；Special pin end is made of the shoulder that links closely, sealing spherical surface and protection shoulder, and special female connector is by die nipple screw thread, sealing cone
With protection shoulder composition, special pin end and special female connector both ends are connect with nonmetal flexible composite soft tube；Female coupling tap screw thread and
Die nipple screw thread plays connection function, without sealing；The sealing cone of close contact only plays primary seal with sealing spherical surface,
Without playing connection function, protection shoulder plays protection sealing cone and sealing spherical surface and secondary sealing function；It is screwed using common wrench
The quick connection between nonmetallic composite soft tube can be completed in hex bolts, and during the connection process, hex bolts is tight by pushing
Button shoulder can establish on special pin end the close contact sealed on spherical surface and special female connector between sealing cone, to realize
The sealing of non-threaded connector and quickly connection, it is entirely avoided the sealing problem generated by thread failure.
The present invention has the following advantages that：
Only with common wrench, the quick connection of nonmetal flexible composite soft tube can be realized using the present invention, using non-threaded
The sealing structure of corrosion resistant alloy spherical surface-conical surface cannot be only used for all kinds of corrosive mediums, and can effectively prevent because of thread failure
And the sealing problem generated, the technical barrier that joint area is easy to happen gas infiltration is efficiently solved, in particular in desert
Very big side is brought for the nonmetal flexible composite soft tube Fast Installation of the corrosive mediums such as transporting oil air water, migration and repair
Just.
