The utility model further discloses a pipeline connecting structure adopting the connector. The technical scheme has the advantages of simple structure, low cost, convenience for installing, good sealing effect, and the like.
Description
Technical field
The utility model relates to the pipeline connection technology field, relates in particular to a kind of pipeline leakproof connector and adopts the pipe connecting structure of this pipeline leakproof connector.
Background technique
Assembling pipe joint is the important device during the every profession and trade pipeline connects, and the assembling pipe joint of strict demand is more particularly arranged for sealing, pipeline error compensation etc., and the quality of its structure and performance directly influences the effect of pipeline.At present straight tube connect general adopt flange and pipe jointer arranged; Flange plate is a kind of being rigidly connected; Effect is not as pipe jointer in pressure piping; Have rubber seal in the pipe jointer metal shell, sealing effect and dismounting aspect all are superior to flange, but existing pipe jointer exists complex structure, cost height, shortcomings such as inconvenience, sealing effect difference are installed.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of the utility model provides a kind of pipeline leakproof connector and pipe connecting structure, have simple in structure, cost is low, advantages such as good are imitated in easy for installation, sealing.
In order to reach above-mentioned purpose, the technological scheme below the utility model has adopted:
A kind of pipeline leakproof connector; Comprise the metal body; Form the interior puncture of annular both sides sunken and that puncture falls in this annular on the tube wall in the middle of the said body and be respectively equipped with the circular groove that can hold seal ring, the internal diameter of tube body of ring slot outside to the mouth of pipe is greater than the inboard internal diameter of tube body that falls into to annular interior puncture of circular groove.
The utility model is owing to adopted above technological scheme; The inboard internal diameter of tube body that falls into to the interior puncture of annular of circular groove closely cooperates with the connecting tube external diameter is corresponding; So not only guaranteed the coaxality of two connecting tubes; And make the interior pressure of pipeline that is applied on the seal ring reduce greatly, guaranteed good sealing effect; The two-port of connector body is bigger at the initial bore of installation; Through the reducing instrument reducing processing is carried out at connector annular seal groove to mouth of pipe position after inserting connecting tube; Make it to be closely connected, seal ring closely is pressed between connector and the pipeline with connecting tube.
As preferably, the internal diameter of tube body of said ring slot outside is 102%～106% of the inboard internal diameter of tube body of circular groove.Rational in infrastructure like this, be easy to reducing processing and connector body and be difficult for intensity reduction even damage.
A kind of pipe connecting structure; Comprise first pipeline, second pipeline and connector; Form the both sides that puncture falls into and puncture falls in this annular in the annular on the tube wall in the middle of the said connector body and be respectively equipped with the circular groove that can hold seal ring; First pipeline and second pipeline are inserted into the interior puncture of annular respectively and fall into from connector body two ends; Seal ring is housed in the circular groove, and wherein, said connector is in the corresponding drive fit of external diameter of the internal diameter of tube body of ring slot outside to the mouth of pipe and first pipeline, second pipeline; Said connector circular groove inboard to the annular the corresponding drive fit of external diameter of the sunken internal diameter of tube body of puncture and first pipeline, second pipeline, said seal ring is pressed between connector and first pipeline, second pipeline.That the present technique scheme has is simple in structure, cost is low, advantages such as good are imitated in easy for installation, sealing.
As preferably, said connector is a metalwork.
