Abstract
The utility model discloses a pipeline anti-leakage connection structure which comprises pipelines and flanges, wherein the pipelines are opposite in the left and right direction, and the flanges are used for connection. A protrusion is arranged on a connection end face of a left pipeline, a groove matched with the left pipeline is formed on the connection end face of a right pipeline, a convex edge is arranged on the lateral face where the pipeline are connected with each other, the end face of a connection end of the convex edge is vertical, a seal groove is arranged on a surface, a recessed face is formed in a back face, the left ends and the right ends of the pipelines are respectively connected with the flanges, the flanges are tightly matched with the back face of the convex edge, and the flanges are connected together through axial fastening devices. The pipeline anti-leakage connection structure is good in clamping effect and is convenient to install and use.
Description
Technical field
The utility model relates to a kind of pipeline anti-leakage linkage 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 easily occurs leaking.
The model utility content
The utility model provides a kind of clamping effective, the pipeline anti-leakage linkage structure of being convenient to install and use.
The utility model technical solution problem provides following scheme:
A kind of pipeline anti-leakage linkage structure, comprise a left side that is connected, right relative pipeline and the flange plate that is connected connecting, it is characterized in that: the connecting end surface of described left pipeline is provided with projection, the connecting end surface of described right pipeline is provided with left pipeline and accompanies the groove that closes, the interconnected side of described pipeline has flange, the end face of the connecting end of described flange is vertical, the surface is provided with seal groove, the back side has concave face, described pipeline is left, right two ends 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 provided with seal ring between the described left and right pipeline.
The utility model is on traditional flange basis, center at flange is provided with through hole, 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.
