The present invention relates to a pipe connector, in particular to a quick tee joint component and a drilling jig component specially for drilling.
A quick tee joint is used for a horizontal or vertical connection point so as to connect a branch pipe to any position in a main pipe, without dismounting or replacing an original main pipeline, and has quick convenient installation and good sealing property. As shown in
In order to overcome the shortcomings mentioned hereinabove, the present invention provides a quick tee joint component and a drilling jig component specially for drilling.
The quick tee joint component comprises a press ring and a quick tee joint body both buckled to fasten a main pipe inside; the middle of the quick tee joint body is provided with a downward branch pipe vertical to the main pipe; and two ends of the press ring and the quick tee joint body are fastened by bolts.
Further, the quick tee joint body outside the nozzle of the branch pipe is provided with a groove, and the groove is provided therein with a seal ring.
Further, the branch pipe is a straight pipe or bent pipe.
Further, the nozzle of the branch pipe has a lengthening part capable of being inserted into a hole in the main pipe to facilitate positioning and installing and ensure a reamer not to deviate during the reaming process, thereby ensuring the reaming quality.
Further, the lengthening part has a notch for guiding accumulated liquid to flow out and preventing the fluid from accumulating at the lowest point of the pipe for long time and affecting the working efficiency, thereby avoiding corrosion and extending the service life of the pipe.
Furthermore, a drilling jig component special for the quick tee joint component comprises the press ring, a drilling jig body is located below the press ring, the press ring and the drilling jig body are buckled to fasten a main pipe inside, two ends of the press ring and the drilling jig body are fastened by bolts, a threaded hole in the middle of the drilling jig body is connected with a bushing vertical to the main pipe, and the bushing is made of a high-hardness metal material.
For installation of a quick tee joint, a drilling jig for quick tee joint is firstly installed on a pipe where a branch pipe is to be added. A bushing of the drilling jig is in threaded connection with the drilling jig, to achieve convenient replacement, and is made of a high-hardness metal material. Under the limiting action of the bushing, the position of a reamer is ensured not to deviate during the reaming process, thereby ensuring the reaming quality. The requirement for different sizes of holes drilled by the drilling jig can be met by simply changing the size of the bushing of the drilling jig. Once reaming is done, fastening bolts are unscrewed so as to remove the drilling jig and a quick tee joint body is installed. A lengthening part of the quick tee joint body guarantees the installation position accuracy of the quick tee joint. In case of vertical installation of the quick tee joint, a notch in the lengthening part allows accumulated liquid to flow out to prevent the fluid from accumulating at the lowest point of the pipe for long time and affecting the working efficiency, thereby avoiding corrosion and extending the service life of the pipe.
Hereinafter the technical solutions in embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the invention. It is apparent that the embodiments described herein are only part rather than all of the embodiments of the invention. Based on the embodiments of the invention, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the invention.
