Description
Technical field
The utility model relates to a kind of assembling pipe joint, relates in particular to a kind of metallic conduit anchor ear connection set.
Background technique
At present, known metallic conduit Placement mainly contains following several:
1. metal tube directly welds.This kind Placement is the Placement between a kind of metallic conduit, the pipeline join strength height of welding, but this kind Placement is to operate at the construction field (site), construction labor intensity is big, and work efficiency is low, can not be in inflammable and explosive place operation, and non-dismountable, generally only be used for the permanent connection of pipeline.
2. flange connects.It is a kind of the most frequently used Placement that flange plate connects, it connects reliable, can be used for, in the low pressure line, flange plate is a standard piece, can be connected with equipment with the various pump housings easily, but it needs welding at the scene, wants earlier the angle of flange plate to be found accurately the bolt hole alignment of both sides flange plate before the welding, inferior connection will be welded at the scene, can not be in inflammable and explosive place operation, construction is inconvenient, and intensity is big, the flange plate Placement is because flange plate is to adopt machine cut to process, connecting bolt on the flange plate is more, has increased cost of material and installation cost, is a kind of commonly used and expensive Placement.What the connection sealing means of flange plate had determined its seal ring bears one class of pressure under 4Mpa, thus can only be used for, in the low pressure line system.
The model utility content
The purpose of this utility model provides a kind of good airproof performance, bears the high metallic conduit anchor ear bindiny mechanism of pressure.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: design a kind of metallic conduit anchor ear bindiny mechanism, its key is: the inner ring of A. anchor ear has circular groove, and there is the connection boss at its two ends, on this boss through hole are arranged; B. bolt passes this through hole, and anchor ear is fastenedly connected in twos, makes anchor ear form annulus; C. in the circular groove of anchor ear inner ring, seal ring is housed; D, described anchor ear hoop are connected on the joint of two pipe joints, the welding of this pipe joint one end and metallic conduit, and the convex edge of the other end is stretched in the circular groove of anchor ear and is touched with the seal ring butt.
There is axial clearance in described metallic conduit anchor ear bindiny mechanism between the end face of two pipe joints of anchor ear joint.
Described sealing circle internal diameter is less than the tube head external diameter, and section is interior ring open type rectangle.
The utility model is used for the connection of metallic conduit, and wherein pipe joint adopts metal casting to form, and does not need to carry out machine cut processing again; Anchor ear adopts metal casting to form or composite material, and the glass fibre reinforced plastic material mold pressing forms, and does not need to carry out machine cut processing again; Pipe joint and anchor ear can be produced in batches, the manufacturing efficiency height, and cost is low.Seal ring adopts synthetic rubber processing.Connecting bolt is a standard piece.
Pipeline before installation with pipe joint weld metal pipeline, the two ends of pipe fitting, during installation with two tube heads to together, after seal ring is installed in the joint, block tube head with two quick anchor ears, on anchor ear, two anchor ears are fixed and all can with two bolts.When if the pipeline of rapid pipe joint will be connected with other, at an end welded stub connection of a steel pipe (transition tube), the other end welding all can with the pipe joint of the identical Placement of other pipeline.
Be contained in two internal diameter of the seal ring on the tube head less than the tube head external diameter, and section is interior ring open type rectangle, thereby certain pretightening force arranged, guaranteed closely to contact between seal ring and the tube head in the joint; Connection set has only several parts to form, and is simple in structure, with low cost; Anchor ear loam cake, lower cover are that identical two semicircle bandings connect, and have interchangeability, only connect with two bolts between the upper and lower cover.Realized the rapid of installation.
Remarkable result of the present utility model is: simple in structure, cost is low, and good airproof performance bears pressure height (can bear 10Mpa pressure), and easy to install quick.
