Abstract
The canal house-service T-branch assembly comprises a house-service pipe which is of T-branch shape, a T-shaped pipe and a locking nut. Inner thread is provided in the upper port of the T-shaped pipe, and the lower end of the thread is a semi-button which is blocked up with a pipe plug, Outer thread is provided in the lower port of the T-shaped pipe, and the lower port of the thread also is a semi-button, inner thread is provided on the side end of the T-shaped pipe, and the inside of the thread is also a semi-button; the inside wall edge of the house-service port on the T-branch house-service pipe forms a flare groove which is inclined outside, wherein an seal ring is embedded in the flare groove, the inside of the flare groove is covered with inner thread with semi-button and the outside wall of the flare groove is covered with outer thread; the lower port of the T-shaped pipe is covered with the locking nut, a supporting ring and the seal ring, is screwed on the T-branch house-service pipe, and is locked through the locking nut on the tee pipe. The pipe member and the triplet can be designed and made into general purpose members and can be generally used and interchanged during the installment and maintenance, thereby the utility model has the advantages of reasonable structure, low costing, convenient installment and maintenance.
Description
(1) technical field
The utility model relates to a kind of pipeline connecting device, particularly relates to a kind of pipeline house lead in threeway assembly parts.
(2) background technique
In pipeline construction, constantly adopt new material, new product, new technology, new process at present, improved Safety performance widely, installation has also made things convenient for a lot.But also there is different defectives in the part, particularly garden pipeline and house lead in inlet tube joint, the position of the screw thread school is tight sometimes pipeline house lead in is not on the contrary not just, have to return a bit for centering but leakage has taken place, the length of screw thread cover is difficult for again grasping, having grown the destroyed and screw thread of zinc-plated anticorrosive coat is exposed to and is very easily corroded and corrosion outward, the long tube wall attenuate that causes of screw thread cover, the mechanical strength of pipe is weakened, so that in a single day pipeline is subjected to the external force effect, just easily rupture at the screw thread place.
(3) summary of the invention
The utility model provides a kind of good sealing effect at above defective, is difficult for leaking, and easy for installation and screw thread place is difficult for taking place the pipeline house lead in threeway assembly parts of fracture.
The technological scheme that adopts is:
Pipeline house lead in threeway assembly parts comprises a home-in-pipe that is threeway shape, and its structure outline is that it also comprises threeway body and a locking nut.The upper end-hole of threeway body is provided with internal thread, so that it is stopped up with plug, lower end mouth be provided with outside thread and near lower end mouth be half the button screw thread, be connected with the house lead in port of the home-in-pipe that is threeway shape with its screw thread, the side ports of threeway body is provided with internal thread, and the inner portion of its screw thread also is half button, connects with the mini three links connecting tube of house lead in its screw thread, partly detain screw thread one and be the intensity that increases the pipe skin, moreover good sealing effect and be exposed in soil or the air and corrosion so as not to screw thread.The inner wall edge of house lead in port that is the home-in-pipe of threeway shape falls into outward-dipping flare groove, and flare groove has been embedded in seal ring, and inner portion is with the internal thread of half button, and outer wall is with outside thread.The lower end mouth of threeway body cover upper locking nut, bracing ring, seal ring and the home-in-pipe that is threeway shape be with being threaded, and locked by the locking nut that is nested with on the threeway body.
The flare inclined-plane, outer ring of above-mentioned seal ring is pressed into seal ring in the flare groove of house lead in port of the home-in-pipe that is threeway shape the tubaeform inclined-plane of seal ring and flare groove tight connecting.
Above-mentioned bracing ring be positioned at seal ring above, a gap is arranged on the plane of bracing ring, outer wall is the flare inclined-plane also, tubaeform inclined-plane upwards during installation, compress with locking nut, sealing is tighter like this, and the threeway body can rotate centering among a small circle and can not reveal again.
The inner wall edge of the side ports of above-mentioned threeway body house lead in has outward-dipping flare groove, flare groove has been embedded in seal ring, bracing ring is arranged above the seal ring, the inwall of the inner portion of groove is provided with half button internal thread, with the lower end mouth of the mini three links connecting tube of house lead in being threaded, the groove outer wall is provided with outside thread, in order to be locked with locking nut.
The utility model is rational in infrastructure, cheap, and installation, maintenance is very convenient, and pipe fitting, threeway can design and make general part, can general and exchange during installation, maintenance.Screw thread is short and do not expose and greatly improved corrosion resistance, has increased the mechanical strength of link pipe skin simultaneously.Adopt seal ring and bracing ring two seals to make sealing tighter, and the threeway body that is rotationally connected does not among a small circle influence sealing yet.

(5) embodiment
Embodiment one
Shown in accompanying drawing 1-3, pipeline house lead in threeway assembly parts of the present utility model is made up of home-in-pipe 1, threeway body 5, locking nut 4, seal ring 2, a bracing ring 3 that is threeway shape.The upper end-hole 6 of threeway body 5 is provided with internal thread, its screw thread by under be half button, and it is stopped up with plug, lower end mouth 7 is provided with outside thread, its screw thread also is half button by lower end mouth 7, and its side ports 8 is provided with internal thread, and its screw thread is inner also to be half button, partly detain screw thread one and be the intensity that increases the pipe skin, moreover good sealing effect and be exposed in soil or the air and corrosion so as not to screw thread.The inner wall edge of house lead in port 9 that is the home-in-pipe 1 of threeway shape falls into outward-dipping flare groove, the inner internal thread that is with half button, and outer wall is with outside thread.The lower end mouth 7 cover upper locking nuts 4 of threeway body 5, bracing ring 3, seal ring 2 are threaded with home-in-pipe 1 usefulness that is threeway shape.Earlier seal ring 2 is pressed in the flare groove of house lead in port 9 of the home-in-pipe 1 that is threeway shape the tubaeform inclined-plane of seal ring 2 and the flare groove tight connecting of house lead in port 9.Then the bracing ring 3 that a gap is arranged on the plane is lain in the top of seal ring 2 and locked by the locking nut 4 that is nested with on threeway body 5.
