Abstract
The utility model discloses a flange-type pipeline connecting structure, which comprises a connecting main body and the pipelines. A flange is fixed on the connecting main body. The characteristic lies in that a capacity room is arranged in the connecting main body to let the pipeline end insert in. A seal ring, a supporting ring, a tightening ring and a pressing flange are arranged on the pipeline in turn. The seal ring, the supporting ring and the tightening ring are fixed on the pipeline through a locking element arranged on the flange and the pressing flange. The pipeline is fixed with the connecting main body through the tightening ring. The utility model provides reliable seal and fast convenient installation.
Description
Technical field
The utility model relates to a kind of connecting structure, particularly a kind of pipeline connecting structure that is applied on the flange-type connection main body.
Background technique
In pipeline is installed, utilize flange that two segment pipes or pipeline and valve body are coupled together usually.In installation process, at first flange is fixed on an end of pipeline by the mode of welding or be threaded, utilize bolt that two segment pipes or pipeline and pipeline are docked with flange on the valve body then, fixedly connected with valve body with pipeline, pipeline to realize pipeline.Pipeline that links together by this Placement and the sealing between pipeline or pipeline and the valve body are to realize by the seal ring that is installed on two flange facings, adopt the sealability of flanged connecting structure of this sealing means unreliable, leak easily, simultaneously in installation process, at first need with the flange welding or by being threaded on the pipeline, thereby make and install loaded down with trivial detailsly, the installation rate of pipeline is caused very big influence.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of good sealing effect, flange-type pipeline connecting structure quick and easy for installation.
The technological scheme that its technical problem that solves the utility model adopts is:
Flange-type pipeline connecting structure, comprise and connect main body and pipeline, connect on the main body and be fixed with flange, it is characterized in that being provided with in the described connection main body containing space that inserts for pipe end, be set with seal ring, roof pressure ring, locking ring and supported flange on the described pipeline successively, seal ring, roof pressure ring, locking ring are fixed on the pipeline by the fastening piece that is installed on flange and the supported flange, pipeline by locking ring with to be connected main body fixedly connected.
As the improvement of the above-mentioned mode of execution of the utility model, the internal surface of described locking ring is provided with the seamed edge of annular.
As the further improvement of the above-mentioned mode of execution of the utility model, the inwall of described connection main body and pipeline is filled out and is lined with plastic layer.
Above-mentioned fastening piece can adopt bolt and nut.
The beneficial effects of the utility model are: flange-type pipeline connecting structure employing of the present utility model is arranged on to connect and supplies the containing space of pipeline insertion to reach seal ring, roof pressure ring, locking ring and the supported flange that is sleeved on successively on the pipeline in the main body, during installation, supported flange, locking ring, roof pressure ring and seal ring need only be enclosed within on the pipeline, pipeline is inserted in the containing space that connects main body, tightening fastener parts, realize sealing thereby the propelling force of utilizing fastening piece makes roof pressure ring crush seal circle, and sealing is reliable; The locking ring radial contraction is locked at pipeline on the connection main body simultaneously, thereby installs very convenient quick; Internal surface at locking ring is provided with annular seamed edge, with the friction factor of increasing locking ring and pipeline external surface, thereby helps Pipeline lock is got tighter; The inwall of connection main body and pipeline is filled out and is lined with plastic layer, thereby fluid and metallic conduit are separated, and contacts and corrosion with fluid to prevent metal, thereby can prevent that fluid from being polluted.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an assembling schematic representation of the present utility model;
Fig. 2 is the schematic perspective view of locking ring.
Embodiment
With reference to Fig. 1, a kind of flange-type pipeline connecting structure disclosed in the utility model comprises connecting main body 1 and pipeline 2, is fixed with flange 3 on connection main body 1, connects to be provided with the containing space 4 that inserts for pipeline 2 ends in the main body 1.
On pipeline 2, be set with seal ring 5 successively, roof pressure ring 6, locking ring 7 and supported flange 8, during installation, insert in the containing space 4 end of pipeline 2, seal ring 5, roof pressure ring 6, locking ring 7 is fixed on pipeline 2 and is connected between the main body by the fastening piece that is installed on flange 3 and the supported flange 8, seal ring 5 is by 6 compressions of roof pressure ring, thereby realize pipeline and the sealing that is connected between the main body, while locking ring radial contraction, make pipeline 2 by locking ring 7 with to be connected main body 1 fixedly connected, thereby supported flange need not be fixed on the pipeline by the mode of welding or be threaded, thereby install very convenient quick.
Fastening piece can adopt bolt 11 and nut 12 as shown in the figure, can certainly adopt the fastening piece of other structure, is not described further at this.
With reference to Fig. 2, be provided with the seamed edge 9 of annular at the internal surface of locking ring 7, strengthening the friction factor of locking ring and pipeline external surface, thereby help Pipeline lock is got tighter.
Fill out at the inwall that connects main body 1 and pipeline 2 and to be lined with plastic layer 10, thereby fluid and metallic conduit are separated, contact and corrosion with fluid to prevent metal, thereby can prevent that fluid from being polluted.
