Abstract
The utility model discloses a connector structure of extrusion forming. The connector structure comprises a connector body with the two ends provided with external threads, two nuts and one end of a pipe to be connected, wherein the two nuts are matched with the external threads at the two ends of the connector body and installed on the pipe to be connected, one end of the pipe to be connected is arranged in the connector body, and a flange is arranged on the outer side face of one end of the pipe to be connected. A sealing gasket is arranged between the flange at one end of the pipe to be connected and the connector body. The flange at one end of the pipe to be connected carries out axial location on the nuts through flange plates arranged at the outer ends of the nuts. The flange and the flange plates of the nuts make contact in a conical face mode. Preferably, the included angle between a conical face and an axis of the pipe is 24 degrees. The design of conical face contact between the flange and the nuts enables assembling torque to be low and installation to be safe. The extrusion forming process can be adopted in the flange, and therefore the manufacturing process is fast and simple. Due to the sealing gasket, the sealing effect is good, leakage is avoided, and the connector structure can be disassembled and assembled repeatedly and can bear medium and high pressure. Moreover, the dimension range of a steel pipe can reach 4-42mm, and therefore the use range is wide.
Description
Technical field
The utility model relates to joint, need not to be welded in the extrusion modling joint structure of pipe connection system while specifically relating to a kind of the assembling.
Background technique
At present, traditional hydraulic system pipeline often adopts the welding pipeline, and jointing adopts Welded fitting or welding type flange.This carries out pipeline construction under inflammable, explosive environments often can cause serious accident.In addition, because any welding pipeline can not be accomplished 100% flaw detection, weld joint is perishable, the weld seam sealing-off, pore etc. is arranged, and therefore is easy to cause the welding pipeline leakage.
Summary of the invention
For above-mentioned situation, the utility model provides a kind of extrusion modling joint structure, enlarging is set and seal ring is realized being tightly connected of pipeline by the tube end connecting, cause serious accident thereby solve the welding pipeline under inflammable, explosive environments, weld seam is easy to the problem that causes pipeline to reveal.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of extrusion modling joint structure, comprise that two ends are provided with externally threaded fittings body, with fittings body two ends outside thread, coordinate and are loaded on two nuts on the pipe that will be connected, it is characterized in that, also comprise that being arranged at the inside and outside side of fittings body is processed with an end of the pipe that will connect of one flange;
The outer end of described two nuts is provided with a flange plate, and the inner side surface of described flange plate is the middle recessed conical surface;
End face close to is the plane vertical with tube axis to the flange of one end of the described pipe that will connect from tube end, and end face and the inboard conical surface of nut flange plate away from matches flange from tube end;
Be provided with a sealing gasket between the flange of the described pipe that will a connect end and fittings body.
Further, the angle of the axis of the flange of the described pipe that will the connect end end face away from and pipe from tube end is 24 °.
Further, the perpendicularity of the axis of the end face of the described pipe that will a connect end and pipe is ± 0.5 °.
Further, the wedge angle abate of the described pipe that will connect an end end, chamfer dimesion is in 0.2 * 45 °.
The beneficial effects of the utility model are, the conical surface design of nut flange plate makes the moment of torsion of assembling low and safety is installed.The flange of pipe one end that connects can adopt extrusion forming process, and working process is simple fast.The use of sealing gasket makes the utility model good sealing effect, without leaking, and can repeat dismounting; Can also bear middle high-pressure, Maximum operating pressure can reach 800bar.The steel pipe sizes scope can reach 4 – 42mm, and using scope is wide.
Description of drawings
Fig. 1 is the structural representation of a kind of extrusion modling joint structure of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand,, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of extrusion modling joint structure, comprise two ends be provided with externally threaded fittings body 1, with fittings body two ends outside thread, coordinate and be loaded on two nuts 2 on the pipe that will connect, be arranged at outer side surface in fittings body be processed with together with the end 3 of the pipe that will connect of flange.
The outer end of described two nuts 2 is provided with a flange plate, and the inner side surface of described flange plate is the middle recessed conical surface.End face close to is the plane vertical with tube axis to the flange of one end 3 of the described pipe that will connect from tube end, and end face and the inboard conical surface of nut flange plate away from matches flange from tube end.Be provided with a sealing gasket 4 between the flange of the described pipe that will a connect end 3 and fittings body.
Wherein, the angle of the axis of the flange of the described pipe that will a connect end 3 end face away from and pipe from tube end is preferably 24 °.The perpendicularity of the end face of the described pipe that will a connect end 3 and the axis of pipe is ± 0.5 °.The wedge angle abate of the described pipe that will connect end 3 ends, chamfer dimesion is in 0.2 * 45 °.
The utility model in use, is measured the blank size of the pipe that will connect according to actual needs, with sawing machine, carries out blanking, should be that sawing machine is mixed different saw blades or saw blade according to the unlike material of the steel pipe that will cut.Can not use pipe cutter or grinder to carry out blanking.
After blanking, burr is removed in the end of pipe, carry out simultaneously chamfering.Whether vertical with the axis of pipe with the pipe end face of angle ruler or leveling instrument inspection cutting, the acceptable tolerance of perpendicularity is ± 0.5 °, and chamfer dimesion should be controlled in 0.2 * 45 °.Wipe greasy dirt and impurity on pipe with clean rag, guarantee the pipe end cleaning.Mix suitable mould according to the size of pipe to machine for extrusion molding, prepare the Female connector fittings 2 of correct specification, it is contained on the processing end of pipe.With the mould of machine for extrusion molding, pipe processing end is squeezed out flange automatically, after sealing gasket 4 is passed tube end and is pressed on flange, then fittings body 1 and nut 2 are screwed, pipe is realized being tightly connected by a kind of extrusion modling joint structure of the utility model.
