In a word, traditional Placement has assembling length consuming time, is not easy to maintenance, sealing effect is undesirable and shortcoming such as on-the-spot machining screw inconvenience, and the inferior complex environment in ore deposit can't use deficiencies such as Welded fitting.
The model utility content
The purpose of this utility model provide a kind of simple in structure, need not pipe thread, assembling connect hours short, can improve speed of application greatly, be convenient to keep in repair and the novel quick coupling of good sealing effect, can effectively overcome fluid and carry inflammable and explosive occasions such as the on-the-spot machining screw inconvenience of hard material pipeline and mine can't use the first-class deficiency of welding type quick pipe connecting.
For achieving the above object, the technical solution of the utility model is: a kind of novel quick coupling, comprise two female joints that are oppositely arranged and the sub-joint that is connected female joint, female joint comprises the hollow tube body, hollow tube body one end is provided with hole clipping, the middle part is provided with the conical surface screw thread, the hollow tube body the other end is cut with equally distributed four axial grooves along the circumferential direction, and axial groove the inner extends to conical surface screw thread place; Sub-joint comprises joint body, and the joint body two ends are respectively equipped with a road sealing groove, the middle part is provided with the twice draw-in groove, is provided with seal ring in the seal groove; The hollow tube body interior is inserted with U-shaped card by hole clipping, and U-shaped card middle part is positioned at draw-in groove, and the conical surface screw thread place of female joint is provided with the cone locking nut.
Described cone locking nut outside is provided with tightening nut and retaining nut successively.
Be provided with sleeve pipe in the hollow tube body of described female joint, casing length is greater than the length of axial groove.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises two female joints that are oppositely arranged and the sub-joint that is connected female joint, female joint comprises the hollow tube body, hollow tube body one end is provided with hole clipping, the middle part is provided with the conical surface screw thread, the hollow tube body the other end is cut with equally distributed four axial grooves along the circumferential direction, and axial groove the inner extends to conical surface screw thread place; Sub-joint comprises joint body, and the joint body two ends are respectively equipped with a road sealing groove, the middle part is provided with the twice draw-in groove, is provided with seal ring in the seal groove; The hollow tube body interior is inserted with U-shaped card by hole clipping, U-shaped card middle part is positioned at draw-in groove, the conical surface screw thread place of female joint is provided with the cone locking nut, it is simple in structure, need not pipe thread, can effectively overcome fluid and carry inflammable and explosive occasions such as the on-the-spot machining screw inconvenience of hard material pipeline and mine can't use the first-class deficiency of welding type quick pipe connecting, the assembling connect hours is short, speed of application be can improve greatly, and maintenance, good sealing effect are convenient to.
2, cone locking nut outside is provided with tightening nut and retaining nut successively, tightening nut screw into the afterbody of cone locking nut and holds out against, can prevent that the cone locking nut from moving back owing to pine is taken place for the effect of axial force, the retaining nut screw into the afterbody of tightening nut and holds out against, can prevent that the tightening nut pine from moving back, can improve connection reliability greatly.
3, the utility model applicable to the laying of ground water pipe and other liquid transmission pipelines, rush to repair and speedily carry out rescue work, also can be used for installing and using of pipeline under the inflammable and explosive complex environments such as colliery, Applicable scope is wide.
