Abstract
The utility model discloses a pipeline connecting structure. The pipeline connecting structure comprises pipelines which are connected and flange plates used for connecting the pipelines. Protruding edges are formed on the end faces where the pipelines are connected. End faces of the connecting ends of the protruding edges are perpendicular to each other. A sealing groove is formed in the surfaces of the protruding edges, and concave surfaces are arranged on the backs of the protruding edges. The flange plates are respectively connected with the left ends of the pipelines and the right ends of the pipelines. The flange plates are firmly matched with the backs of the protruding edges and connected with each other by the adoption of an axial clamping device. The pipeline connecting structure is good in clamping effect and convenient to install and use.
Description
Technical field
The utility model relates to a kind of pipe connecting structure.
Background technique
In the existing technology, the valve adpting flange is widely used in the pipeline industry, but in general pipeline connection procedure, vertical flange does not have power radially in clamping process, just be difficult to connect, and so just is difficult to connect, and occurs easily leaking.
The model utility content
The utility model provides a kind of clamping effective, the pipe connecting structure of being convenient to install and use.
The utility model technical solution problem provides following scheme:
A kind of pipe connecting structure, comprise the pipeline that is connected and the flange plate that is connected connecting, it is characterized in that: the interconnected end face of described pipeline has flange, the end face of the connecting end of described flange is vertical, the surface is provided with seal groove, and the back side has concave face, and the left and right two ends of described pipeline are mounting flange respectively, cooperate between described flange plate and the flange back face closely, adopt between the described flange plate to axially fasten device and link together.
Be inlaid with seal ring on the connecting end surface of described pipeline.
The utility model is on traditional flange basis, center at flange is provided with through hole, and flange plate is placed on the arranged on left and right sides of pipeline flange connector, adopts axial connection set that flange is linked together, in connecting end surface, add seal ring, effectively avoided the leakage at pipe joint place.
Description of drawings
Fig. 1 is structural representation of the present utility model.
