Abstract
The utility model discloses a pipeline-connecting joint which comprises a first connecting pipe and a second connecting pipe, wherein the first connecting pipe is in butt joint with the second connecting pipe, a nut is fixedly sheathed at the butt joint part between the first connecting pipe and the second connecting pipe, the upper part of the nut is fixedly sheathed on the first connecting pipe, the lower part of the nut is fixedly sheathed on the second connecting pipe; a circumferential groove is arranged on the end surface of the first connecting pipe, which is in contact with the second connecting pipe; a seal ring is arranged in the circumferential groove, and the seal ring is clung to the end surface of the second connecting pipe. By adopting the pipeline-connecting joint, the sealing performance of a pipe joint can be improved; and the pipeline-connecting joint has the characteristics of skillful concept, simple structure, easiness in implementation, easiness in detachment, good reliability and the like.
Description
Technical field
The utility model relates to a kind of pipe joint, especially relates to a kind of pipe connector lug.
Background technique
Conventional pipe joint generally includes straighttube-type joint and bent-tube boiler joint and threeway tubular type joint, the pipe joint of these three kinds of structures all is to be made of the outside thread or the internal thread that are arranged on pipe fitting open end zone, make and adopt the structure that is threaded between pipe joint and the connecting tube, this kind Placement structure is comparatively simple, but there is a serious deficiency, that is exactly that the sealability of existing pipe joint is all relatively poor, liquid or gas overflow between each connected element of pipe joint easily, thereby cause waste or reduce the interior pressure of pipeline, necessitate so solve the sealability of pipe joint.
The model utility content
Technical problem to be solved in the utility model is to provide the pipe connector lug of a kind of novelty simple in structure, favorable sealing property.
The technical solution of the utility model is as follows: a kind of pipe connector lug, its main points are: comprise first connecting tube and second connecting tube, described first connecting tube and the butt joint of second connecting tube, be installed with nut at this first connecting tube and the second connecting tube joint, this nut top is solidly set on described first connecting tube, the bottom is solidly set on described second connecting tube, be provided with circumferential groove at described first connecting tube with the end face that described second connecting tube contacts, in this circumferential groove seal ring is housed, described seal ring is close to the end face of described second connecting tube.Adopt above structure, after being provided with seal ring on the butt joint end face of first connecting tube and second connecting tube, select the O RunddichtringO for use, adopt nut with first connecting tube and the locking of second connecting tube again, thereby obtain better seal, when using the utility model, only need with the outer end of first connecting tube and second connecting tube and the pipeline that needs be connected respectively argon arc welding weld and can realize reliable connection, simultaneously, dismounting of the present utility model is also comparatively convenient.
The described second connecting tube upper portion side wall is provided with limited step, and described nut lower inner wall is provided with the locking step, and described locking step is close to described limited step, adopts above structure, can realize that first connecting tube is connected with the reliable of second connecting tube.
Beneficial effect: adopt the utility model can improve the sealability of pipe joint; Have be skillfully constructed, simple in structure, implement easily, dismounting easily, characteristics such as good reliability.
Description of drawings
Fig. 1 is a structure intention of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
See also Fig. 1: shown in a kind of pipe connector lug, comprise first connecting tube 1 and second connecting tube 2, described first connecting tube 1 and 2 butt joints of second connecting tube, be installed with nut 3 at this first connecting tube 1 and second connecting tube, 2 joints, these nut 3 tops are solidly set on described first connecting tube 1, the bottom is solidly set on described second connecting tube 2, be provided with circumferential groove 1a at described first connecting tube 1 with the end face that described second connecting tube 2 contacts, in this circumferential groove 1a seal ring 4 is housed, described seal ring 4 is close to the end face of described second connecting tube 2.
In Fig. 1, it can also be seen that: be provided with limited step 2a on described second connecting tube, 2 upper portion side wall, this limited step 2a processes second connecting tube, 2 upper portion side wall to make, also can be that second connecting tube, 2 top outward flangings are made, be provided with locking step 3a on described nut 3 lower inner wall, described locking step 3a is close to described limited step 2a.
The above only is preferred embodiment of the present utility model; it is not restriction with the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
