Abstract
The utility model provides a rotary control self-locking loose jointed tube fitting, which relates to a novel screwless loose jointed tube fitting used for the pipeline connection of water, coal, gas, petroleum, etc., mainly comprising a main body, a cap nut, a sealing ring, a flat washer and a gapped tooth-shaped lock ring. The utility model has further reasonable structure; the butt joint pulling force and the locking degree of tubes are enhanced, and the leak-proof seal is further enhanced. While in use, the utility model can use the already cut tubes directly for pipeline installation.
Description
The utility model relates to the novel no screw thread loose joint pipe fitting that pipelines such as being used for water, coal, gas, oil connects.
At present, in the installation and maintenance process of pipeline,, not be used in machining screw on the pipe during installation, alleviated installer's labor intensity, improved installation efficiency, also brought convenience for simultaneously maintenance owing to use screw-thread-free pipe joint.Therefore, receive praises from customers.
The purpose of this utility model is a kind of locking degree of further strengthening on the basis of former screw-thread-free pipe fitting pipe of design, strengthen butt joint pulling force and leakproof seal effect, bring bigger convenience to installation and maintenance, can fill in the gaps to complete a chain and produce the novel no screw thread loose joint pipe fitting that uses.
Novel screw-thread-free pipe joint provided by the utility model--revolve control self-locking loose joint pipe fitting, it is characterized in that (referring to Fig. 1), the main body of this joint (6) inwall is a cylinder circular cone scalariform, and its end is coniform, and the outer wall two ends are provided with screw thread.It is coniform that nut (2) inwall is cylinder, and an end is provided with screw thread, and it is coniform that the other end is.
In accompanying drawing 1 pipe fitting (left end) main body (6) and nut (2) connecting body, be provided with rectangular seal (8), conical seal ring (7), plain washer (4), opening profile of tooth retainer (3).During use, earlier rectangular seal (8) is inserted the inwall step place of main body (6), again with nut (2), opening profile of tooth retainer (3), plain washer (4), conical seal ring (7) is successively on the outer wall through pipe (1), then pipe (1) is inserted in the main body (6), real with rectangular seal (8) top, with the conical seal ring (7) on the pipe (1), plain washer (4), opening profile of tooth retainer (3) order is close to main body (6), rotary nut (2) docks with main body (6), and operation tool screws nut and main body, reach to install and connect purpose, the installation end.
Accompanying drawing 1: in pipe fitting (right-hand member) main body (6) and nut (2) connecting body: be provided with opening profile of tooth retainer (3), plain washer (4), bowl ring (5).During use, with nut (2), opening profile of tooth retainer (3), plain washer (4) on the outer wall through pipe (1), is set to bowl ring (5) the connection termination of pipe (1) successively again, with pipe (1) together with the accessory of putting on, bowl ring (5), plain washer (4), opening profile of tooth retainer (3) is close to main body (6), and rotary nut (2) docks with main body, operation tool, nut and main body are screwed, reach the connection purpose is installed, install and finish.
Accompanying drawing 2: the two ends of pipe fitting, (right-hand member) structure of external structure and connecting means mode and (accompanying drawing 1), installation method unanimity.
The structure of the utility model accompanying drawing 1 is mainly used in straight joint, straight head, the elbow of becoming, and is characterized in: establish an end loose joint and just can reach direct replacing, the purpose of convenient for maintaining on the pipe fitting that has only two places to connect.The structure of accompanying drawing 2 is mainly used in threeway, four-way and other manifold road and connects, thereby realizes the purpose of the full loose joint of installation pipeline, and be characterized in: each joint of pipeline all can be fitted up flexibly, and is extremely easy to use.Therefore, the utility model compared with prior art, it is further reasonable to have structure, installation and maintenance save time conveniently, labor intensity is little, the characteristics that work efficiency is high.
Drawings and Examples:
Accompanying drawing 1, accompanying drawing 2--are the sectional structure chart that revolves control self-locking loose joint pipe fitting.
Embodiment: revolving shown in the accompanying drawing 1 controlled self-locking loose joint pipe fitting, and its critical piece comprises: main body (6), nut (2), opening profile of tooth retainer (3), plain washer (4), seal ring (bowl-type (5), taper (7), rectangle (8)).Described main body (6) inwall is a cylinder circular cone scalariform, and its end is coniform, and the outer wall two ends are provided with screw thread.It is coniform that nut (2) inwall is cylinder, and an end is provided with screw thread, and it is coniform that the other end is.In main body (6) and nut (2) connecting body, be provided with opening profile of tooth retainer (3), plain washer (4), seal ring ［ bowl-type (5), taper (7), rectangle (8) ］, in the piping erection maintenance process:
(left end) erection sequence of accompanying drawing 1 pipe fitting is: earlier with rectangular seal (8), insert the inwall step place of main body (6), again with nut (2), opening profile of tooth retainer (3), plain washer (4), conical seal ring (7) is successively on the outer wall through pipe (1), then pipe (1) is inserted in the main body (6), real with rectangular seal (8) top, with the conical seal ring (7) on the pipe (1), plain washer (4), opening tooth retainer (3) order is close to main body (6), and rotary nut (2) docks with main body (6), and operation tool screws nut, in screwing process, the conical surface of nut (2) inwall and the outer wall of opening profile of tooth retainer (3) are overlapping, and axially promote plain washer (4), extruding conical seal ring (7), make its expansion, play seal action.Meanwhile, under external force, the conical surface of nut (2) inwall is along the outer inclined-plane motion of opening profile of tooth retainer (3), and compressing opening profile of tooth retainer (3) locking pipe (1), and drive pipe (1) extruding rectangular seal (8) make its sealing.Thereby reach the purpose of connection and fixing tube, install and finish.
(right-hand member) erection sequence of accompanying drawing 1 pipe fitting is: earlier with nut (2), opening profile of tooth retainer (3), plain washer (4) is successively on the outer wall through pipe (1), again bowl ring (5) is set to the connection termination of pipe (1), with pipe (1) together with the accessory bowl ring of putting on (5), plain washer (4), opening profile of tooth retainer (3) is close to main body (6), rotary nut (2) docks with main body (6), operation tool, screw nut, in screwing process, the conical surface of nut (2) inwall and the outer wall of opening profile of tooth retainer (3) are overlapping, and axially promote plain washer (4) and press to bowl ring (5), under the effect of external force, the conical surface of nut (2) inwall is along the outer inclined-plane motion of opening profile of tooth retainer (3), compressing opening profile of tooth retainer (3) is locked pipe (1) and is driven pipe and pushes bowl ring (5) together, makes its expansion, plays seal action.Thereby reach the purpose of connection and fixing tube, install and finish.
Accompanying drawing 2: the inside, two ends of pipe fitting, external structure connecting means mode is consistent with (right-hand member) of accompanying drawing 1.Be mainly used in threeway, four-way, and other manifold road connection, realize full pipeline installation, the purpose of maintenance loose joint.
