Description
Technical field
The utility model relates to a kind of pipe connecting device, particularly a kind of bulge loop formula pipe connecting device.
Background technique
Connection between traditional pipeline road needs to be threaded, need to arrange screw thread at transport pipe two ends, undertaken connecting, sealing by joint, not only manufacture cost is high, and once pipeline occurs that leakage problem appears in damage or joint, is often not easy to maintenance and leak detection, pipeline changes difficulty, sealing effect is poor, and workman is large to the maintenance workload of transport pipe, uses inconvenience.It is very inconvenient that the pipeline road of current use couples together, and link easily lost efficacy, and was unfavorable for the raising of oil transportation operating efficiency.
Chinese patent literature publication number is: CN 102042449 B, patent name is: " pipe joint " comprises connecting rod, the gland nut be threaded connection on connecting rod, described connecting rod is the tubulose of hollow, one end of connecting rod is fixedly connected with taper expander, on connecting rod, the external diameter of expander part is greater than the external diameter of other parts, the other end of connecting rod is with outside thread, connecting rod between taper expander and gland nut is set with spring tube, and the outside of described spring tube is set with stiffening ring; Described stiffening ring is coaxial with gland nut, and the upper end of stiffening ring is fixedly connected on the lower end surface of gland nut; The maximum outside diameter of the taper expander on connecting rod is less than or equal to the internal diameter of pipeline to be connected; The internal diameter of stiffening ring is greater than or equal to the external diameter of pipeline, and the external diameter of the internal diameter of elastomer under force-free state and connecting rod matches, and the external diameter of elastomer under force-free state is at least not more than the maximum outside diameter of taper expander.This sealed connection device for pipeline by taper expander with the connecting rod between gland nut is set with spring tube and realizes being connected, easily occur in process during connection connecting unstable problem, easily cause misplacing between pipeline, cause pipeline Joint failure, cause oil pipe to reveal, be unfavorable for oil transportation operation.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, a kind of bulge loop formula pipe connecting device is provided, realize joint by external fastening element to be connected with the rapid of connecting tube, have low cost of manufacture, manufacturing efficiency high, be easy to operation, connection reliability strong, detect the advantages such as simple.
Its technological scheme is: comprise joint, connecting tube, seal ring, joint and connecting tube are threaded connection, the joint of joint and connecting tube is provided with seal ring, described joint and the joint of connecting tube are provided with external fastening element, described external fastening element comprises inner sleeve and outer sleeve, described inner sleeve and outer sleeve nested encryptions, the both sides of inner sleeve are provided with the outer bulge loop of arc, the both sides of outer sleeve are provided with arc internal chute, the outer bulge loop of arc of inner sleeve matches with the arc internal chute of outer sleeve, and the joint end of inner sleeve and outer sleeve is provided with limit convex block.
The inwall of above-mentioned external fastening element is provided with teeth.
The outside of above-mentioned external fastening element is provided with rotation plush copper.
The beneficial effects of the utility model are: installation, convenient disassembly, anti-vibration, good airproof performance, greatly improve production effect, the application of high carbon steel and superpower composite makes product pressure-bearing high, and applicable model is admittedly wide, and environmental suitability is strong, good seal performance, avoid fed sheet of a media to run and emit leakage, energy saving, prevent the pollution of the environment.
