Description
Technical field
The present invention relates to pipeline interconnection technique field, relate in particular to a kind of enhancing thermoplastic composite tube and withhold joint and connecting means.
Background technique
Strengthen thermoplastic composite tube and mainly constitute usually by three layers, promptly inside and outside plastic layer and be arranged in the middle of the enhancement layer that is composited by reinforcing material.At present,, adopt usually between the tube and tube to strengthen the electric smelting sleeve and connect, adopt usually to withhold joint or strengthen the electric fusion joint flange between pipe and the equipment to be connected, thereby have multiple Connecting format such as flange, screw thread for strengthening thermoplastic composite tube.
At present, existing technology strengthens electric smelting sleeve Placement, the complex manufacturing technology of electric smelting sleeve, and yield rate and manufacturing efficiency are low, and sleeve docks through plastic hot melt with pipeline during connection, and program is more loaded down with trivial details.Because this mode is to serve as to connect supporting mass with the limited plastics of mechanical strength, so join strength and rigidity are lower.For this reason; The Chinese patent publication number is that CN2729492Y, name are called the utility model patent of " high pressure connector lug for fiber enhanced thermoplastic composite plastic tube "; A kind of electric smelting sleeve added metal sleeve and fw frp are disclosed as outer field pipe coupling; Glass fibre reinforced plastics through metal sleeve and winding strengthens the supporting to axial stress and circumference stress respectively, thereby improves join strength and rigidity.But this Placement still need be docked with plastic hot melt, and complex structure, has increased the difficulty of making and attended operation.
Withhold joint as another kind of Placement, constitute by joint core and joint overcoat.During connection, the end of connected pipe is inserted in the gap between joint core and the joint overcoat, tightens through implementing buckle press.Connection between joint core and the joint overcoat then is the end with both, links together through the welding or the mode of snapping.In addition,, also teeth are set, make tube wall produce distortion and raising axially mounting power after withholding on the surface of joint and tube contacts for increasing impacting force.But strengthen composite pipe for the wire rope with certain rigidity, existing technology just makes the inside and outside Surface deformation of tube wall, and middle wire rope enhancement layer still maintains the original state and do not change, and the impacting force that this distortion produced is still limited.Obviously, the present this mode of structure of withholding joint of existing technology is only on two faces that are parallel to each other; Rely on joint core, joint overcoat to withhold with the inside and outside wall of pipeline and be connected; Under the STRESS VARIATION influence, be easy to get loose, the stability and the reliability of use are relatively poor.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing technology, provide a kind of simple in structure, connect firm enhancing thermoplastic composite tube and withhold joint, making things convenient for attended operation, and improve stability and the reliability of using.Another object of the present invention is to provide and use the above-mentioned joint of withholding to carry out the method that pipeline connects.
The object of the invention is achieved through following technological scheme:
A kind of enhancing thermoplastic composite tube provided by the invention is withheld joint, comprises core pipe and outer tube, and said core pipe and outer tube are " L " type and are arranged in parallel; The horizontal segment of said core pipe is a core, vertically section is interconnecting piece, and the horizontal segment of said outer tube is for withholding cover, vertically section being outer connector; Has the gap between said interconnecting piece and the outer connector.During connection, the end of connected pipe is inserted in the core of core pipe and withholding between the cover of outer tube, and enforcement is withheld the back and tightened; In addition, the position, termination of composite pipe can outwards be dug and is clipped in the gap location between interconnecting piece and the outer connector, thereby has strengthened the steadiness that connects.
The present invention withholds joint specifically can take following further measure: the thickness more than the gap between said interconnecting piece and the outer connector and its one deck of composite pipe enhancement layer or one deck is suitable, and the enhancement layer when making connection in the middle of the composite pipe end turns up and is clipped in the gap location between interconnecting piece and the outer connector.
For strengthening impacting force, the present invention withholds the said core of joint and is provided with unidirectional teeth with the internal surface of withholding cover, and said teeth homocline makes the tube wall of withholding the back composite pipe produce distortion and further improve the steadiness that connects to interconnecting piece/outer connector.
In addition, the present invention withholds the said interconnecting piece of joint and outer connector can be flange, connects fixingly between core pipe and the outer tube of joint with flange thereby make, and makes pipeline pass through joint to be connected with another pipeline or external equipment realization flange.
Another object of the present invention is achieved through following technological scheme:
A kind of connecting means of withholding that thermoplastic composite tube is withheld joint that strengthens provided by the invention; Said composite pipe comprises internal layer, skin and is arranged on the middle enhancement layer that is composited by reinforcing material; Use the above-mentioned joint of withholding, with the said core of withholding joint with withhold cover and withhold respectively on the inner and outer wall of composite pipe; The position, termination of said composite pipe is outwards dug and is formed flange, and this flange is clipped in the gap location between said interconnecting piece and the outer connector.The present invention through withholding composite pipe tube wall and clamp the end limit that composite pipe turns up, thereby realize the dual effect of withholding.
The present invention withholds connecting means can take following further measure: the flange of said composite pipe end is the one or more layers enhancement layer that composite pipe exposes.Its reinforcing material can be steel wire or steel cable.Said core is provided with unidirectional teeth with the internal surface of withholding cover, and said teeth homocline is to interconnecting piece/outer connector; Internal layer, skin and the middle enhancement layer of withholding the said composite pipe in back all are wavy distortion.After also promptly implementing to withhold, not only make the inside and outside layer of composite pipe produce distortion, and middle wire rope enhancement layer also produce distortion.
The present invention withholds that connecting means can realize between the interconnecting piece and outer connector of joint through the flange Connecting format, being connected between pipeline and the pipeline, between pipeline and the external equipment.
The present invention has following beneficial effect:
(1) the present invention is through withholding the tube wall of composite pipe, in conjunction with clamping the end limit that composite pipe turns up, thereby on orthogonal, realizes dual compressing.Increased the contact action between joint and the pipeline, the joint is not easy to get loose, and has greatly improved the steadiness and the reliability that connect.
(2) strengthen composite pipe for wire rope with certain rigidity; Not only make the inside and outside layer of composite pipe produce distortion after withholding; And middle wire rope enhancement layer also produces distortion, thereby plays the effect that compresses tubing inner and outer surface and wire rope simultaneously, makes impacting force be significantly improved.
(3) simple in structure, attended operation is convenient, and is widely applicable, thereby more helps promotion and application.
