Abstract

The utility model relates to a loop flange joint for linking the steel frame plastic compound pipeline, aiming at solving the technical problems of sealing face transplacement, invalidation of airproofness and leakage of the current loop flange adapters. The utility model is structurally characterized in that a loop flange(1) is pressed on a flange adapter (2), the contact face between the loop flange(1) and the flange adapter(2) is a flat surface, while two straight pipes(4) are evenly jointed by a connecting bolt(3) that passes through the loop flange(1). The loop flange adapter has the advantages of simple structure, easy installation, reliably sealing and impossible leakage.

Description

Be used for the lap joint flange joint that the steel skeleton plastic clad pipe road connects
Technical field:
The utility model relates to a kind of pipe joint, belongs to a kind of lap joint flange joint that the steel skeleton plastic clad pipe road connects that is used for.
Background technique:
At present, be used for the lap joint flange joint that the steel skeleton plastic clad pipe road connects, the composition structure of its Connecting format is a divided ring, chip flange and connecting bolt, clamping has divided ring between flanged joint on the composite pipe and the chip flange, the surface of contact of divided ring and flanged joint is the inclined-plane, there is certain potential safety hazard in this linkage structure, the distance of bolt between two flanges that connects two flanges is long, influence along with long operation of pipeline and external environment factor, some distortion power is applied to flange connections, produce the sealing surface mutual dislocation, seal failure produces and leaks.
The model utility content:
In order to overcome the easy mutual dislocation of existing lap joint flange joint sealing face, seal failure and to produce the deficiency of leaking, the utility model provides a kind of lap joint flange joint that the steel skeleton plastic clad pipe road connects that is used for, and has simple in structure, easy for installation, the reliable characteristics of leakage that do not produce that reach of sealing during this lap joint flange joint.
The technical solution of the utility model is: a kind of lap joint flange joint that is used for the connection of steel skeleton plastic clad pipe road comprises lap joint flange, connecting bolt and straight tube, one end of straight tube has flanged joint, lap joint flange is close on the flanged joint, the surface of contact of lap joint flange and flanged joint is the plane, and the connecting bolt butt joint of lap joint flange is passed in two straight tube utilizations.
The other end of above-mentioned straight tube has awl and seals.
The utlity model has following beneficial effect: owing to take such scheme, removed the divided ring in the background technique, simplified the structure, shorten the length of connecting bolt, guaranteed installation reliability, easy for installation, sealing is reliable, does not produce leakage, has reduced the cost of product simultaneously.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model.
1-lap joint flange among the figure, the 2-flanged joint, the 3-connecting bolt, the 4-straight tube, the 5-awl seals.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of lap joint flange joint that is used for the connection of steel skeleton plastic clad pipe road comprises lap joint flange 1, connecting bolt 3 and straight tube 4, one end of straight tube 4 has flanged joint 2, the other end of straight tube 4 has awl and seals 5, lap joint flange 1 is close on the flanged joint 2, lap joint flange 1 is the plane with the surface of contact of flanged joint 2, and two straight tubes 4 utilize connecting bolt 3 butt joints of passing lap joint flange 1.This joint has removed the divided ring in the background technique, simplify the structure, shortened the length of connecting bolt 3, guarantee installation reliability, easy for installation, owing to cancelled divided ring, in use can not produce the sealing surface mutual dislocation because of the distortion power of flange connections, sealing is reliable, does not produce leakage, has reduced the cost of product simultaneously.

Claims (2)
