Abstract
The utility model relates to the technical field of pipeline connecting parts, in particular to a pipeline connecting structure with high sealing performance, which comprises male joint flanges for connecting with the left pipeline ends, and female joint flanges for connecting with the right pipeline ends nested with the left pipeline ends, wherein two annular seal rings distributed axially are arranged on the inner sides of the female joint flanges, the two annular seal rings are positioned between the nested parts of the left pipeline end and the right pipeline end, and the male joint flanges are connected with the female joint flange through screws. By adopting the pipeline connecting structure, the leakage risk is reduced, the overall airtightness of a pipeline system is improved, the processing efficiency is high, the processing period is short and the cost of parts is low.
Description
Technical field
The utility model relates to the pipeline connecting parts technical field, and especially a kind of high sealing performance pipeline jointing construction is mainly used in the connection of car air conditioner pipeline.
Background technique
Pipeline be connected with a variety of structures, wherein flange be connected in the car air conditioner pipeline use very general, no matter the sealing part of flange is that negative joint end or male connector end are generally formed by Vehicle Processing, pipeline is processed into one by the mode and the flange of soldering, because pipeline and flange need welding, therefore there is certain risk of leakage.
The model utility content
The technical problems to be solved in the utility model is: shortcoming and deficiency in order to solve above-mentioned existence, a kind of high sealing performance pipeline jointing construction is provided, and eliminate the soldering risk of leakage.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of high sealing performance pipeline jointing construction, have the male connector flange that connects left pipeline termination and the negative joint flange that is connected with the right pipeline termination of left pipeline termination fit, negative joint flange inboard is provided with the O-ring seal of two axial distribution, two O-ring seals are between the suit place of left pipeline and right pipeline termination, with design of Sealing Structure in pipeline inside, avoid using welding manner, reduce the joint risk of leakage.
Further, be connected by screw between described male connector flange and the negative joint flange, simple in structure, dismounting easily.
The beneficial effects of the utility model are, a kind of high sealing performance pipeline jointing construction of the present utility model reduces risk of leakage, improves the whole air-tightness of pipe-line system, the work efficiency height, and the process-cycle is short, and cost of parts is low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an overall structure schematic representation of the present utility model;
Fig. 2 is the utility model partial structurtes male connector flange scheme of installation;
Fig. 3 is the utility model partial structurtes negative joint flange scheme of installation.
Among the figure 1, left pipeline, 2, the male connector flange, 3, right pipeline, 4, the male connector flange, 5, seal ring, 6, screw.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of high sealing performance pipeline jointing construction as Fig. 1, Fig. 2, preferred forms shown in Figure 3, have the male connector flange 2 that connects left pipeline 1 termination and the negative joint flange 4 that is connected with right pipeline 3 terminations of left pipeline 1 termination fit, negative joint flange 4 inboards are provided with the O-ring seal 5 of two axial distribution, two O-ring seals 5 are connected by screw 6 between male connector flange 2 and the negative joint flange 4 between the suit place of left pipeline 1 and right pipeline 3 terminations.
When the connection sealing of pipeline, sealing means adopts radially double flute sealing, seal ring 5 designs in pipeline inside, are connected pipe fitting by the upsetting pressure mode with flange, avoid using welding manner, reduce the joint risk of leakage, owing to adopted two seal rings 5, increase the double seal guarantee, promoted the whole air-tightness of pipe-line system, reduce the consumptive material and the processing cost of flange simultaneously, improved work efficiency.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
