Abstract
The utility model discloses a pipe fitting connector. Arc-shaped threads are arranged on the surface of the connector in a rolling forming mode. The pipe fitting connector comprises arc-shaped taper threads and arc-shaped column threads. The pipe fitting connector is characterized in that damping portions are arranged on the surfaces of the arc-shaped threads. The damping portions can be formed through sand blasting or burring, or the damping portions can be micro grooves. According to the technical scheme, Teflon tapes can be used as connection auxiliary materials during pipe fitting connection, after being wrapped by the thread seal tapes, the connectors are not prone to sliding during connection, working time consumed by anaerobic adhesive solidification is saved, pipe fitting connecting efficiency, safety and sanitation are greatly improved, and modification and maintenance are more convenient and faster.
Description
Technical field
The utility model relates to a kind of pipe fitting and tubing, relates in particular to a kind of metal pipe element linkage structure that need be tightly connected for delivery of liquid or gaseous medium.
Background technique
Improvement along with the raising of people's living standard, particularly housing condition.In increasing new house finishing or the transformation of old residential district, arranging again of pipeline just becomes an important project.Tap water, combustion gas etc. all need can supply to huge numbers of families by the conveying of sealing, durable metallic conduit, and according to the difference of layout design, pipe network need each forms to linking to each other by different pipes, and therefore, the degree of reliability that metal tube connects will directly determine the safe operation of pipe network.
At present, a kind of pipe joint linkage structure based on the circular arc type screw thread is arranged, it is roll forming, so the surface is very smooth.No matter be circular arc type tapered thread or circular arc type male screw, in use, adopt raw meal belt (being teflon) as sealing material usually, coat raw meal belt on the surface of circular arc type screw thread, again with the cross-under of another section pipe fitting phase.But in the practical application, because the smooth raw meal belt that easily causes skids, pipe fitting connects and will get loose.Therefore the pipe joint for such circular arc type screw thread can only adopt the anaerobic adhesive sealing, but in practice of construction, the temperature height can influence the curing time of anaerobic adhesive, does not wait in 3-30 hour usually, greatly reduces working efficiency like this.And anaerobic adhesive gluing requirement standard in construction, be coated with and lacked the meeting seepage, be coated with and remained in the tube wall, the drinking food product industry is used safety and sanitary hidden danger.In addition, in a single day the anaerobic adhesive connecting thread needs repacking or maintenance, needs use high temperature spray gun, and its colloid is melted could be dismantled, and operation is comparatively loaded down with trivial details.
Summary of the invention
The purpose of this utility model is to provide a kind of pipe fitting connecting head, solves metal tube and connects safety, sealing, problem easily.
The utility model realizes that the technical solution of above-mentioned purpose is: a kind of pipe fitting connecting head, described connecting head surface rolling moulding is provided with the circular arc type screw thread, it is characterized in that: described circular arc type thread surface is provided with damper portion.
Further, described damper portion is at least sandblast.
Further, described damper portion is at least burr.
Further, described damper portion is at least fine groove net groove.
The application of technical solutions of the utility model, its remarkable advantage is: can adopt raw meal belt as connecting auxilliary material when pipe fitting connects, connecting head joins after raw meal belt coats and is difficult for skidding, save anaerobic adhesive and solidified spent man-hour, improved efficient and safety and sanitary that pipe fitting connects greatly, and repacking, safeguard more convenient.
Description of drawings
Fig. 1 is the composite structure schematic representation of the utility model pipe fitting connecting head numerous embodiments.
Embodiment
Following constipation closes embodiment's accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
As shown in Figure 1, be the composite structure schematic representation of the utility model pipe fitting connecting head numerous embodiments.From illustrating as seen, this pipe fitting is tee union among this embodiment.But it should be explicitly made clear at this point that the applied pipe fitting of technical solutions of the utility model is not limited only to tee union, it also can be metal tube, bitermitron joint or valve joint etc.Illustrate as seen, the connecting head surface rolling moulding of this tee union 1 is provided with circular arc type tapered thread 11 and circular arc type male screw 12.Under the conventional attaching technology, this tee union 1 twines raw meal belt in the circular arc type thread surface of any connecting head, then screws with required metal pipe butt joint of docking.In order to prevent the slippage of raw meal belt, the utility model under the prerequisite that does not change original structure, shape, is made as damper portion to its surface Machining based on this circular arc type tapered thread structure.
In the specific implementation process, this damper portion can be sandblast 2, burr 4 or fine groove net groove 3, by doing processing such as sandblast, frosted hacking or roll-in at circular arc type tapered thread or circular arc type male screw surface, the smooth surface improvement can be the damping surface.Which kind of as for the damper portion that adopts form in concrete the application, then can select arbitrarily to use.Thus, just can use raw meal belt as sealing material, behind the construction molding that pipe fitting connects, raw meal belt can not skid.The convenience that pipe fitting connects and sealing tightness are ensured.
As fully visible, use the technical solution of the utility model, when connecting, can adopt by pipe fitting raw meal belt as connecting auxilliary material, connecting head joins after raw meal belt coats and is difficult for skidding, save anaerobic adhesive and solidified spent man-hour, improved efficient and safety and sanitary that pipe fitting connects greatly, and repacking, safeguard more convenient.
In addition to the implementation, the utility model can also have other mode of execution, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
