B) a bolt (6)is passed through the through hole to closely connects every two anchor ears (1)together to form a circle. C) a sealed ring(3) with a rectangular gap on the section, is provided at the arc-shape groove formed at the inner ring of the anchor ear. The anchor ear (4) is connected with joint of two pipe connectors (1). The pipe connector (1)is welded to the metal pipe(1)at one end and has a protrude edge formed at the other end to contact with the sealed ring (3)placed in the arc-shape groove of the anchor ear(4). An axial clearance is formed between the surfaces of the two pipe connectors (1). The utility model has the advantages of simple structure, well sealing performance, high bearing ability and easy and quick installation.
Description
Technical field
The utility model relates to a kind of connection set, relates in particular to a kind of pipeline fast connector.
Background technique
At present, known metallic conduit Placement mainly contains following two kinds:
1. welding.This kind Placement is the mouth of pipe butt joint welding that need are connected, and construction labor intensity is big, and work efficiency is low, the quality of connection instability, and non-dismountable, generally only be used for the permanent connection of pipeline.
2. flange connects.This kind Placement is that flange plate is welded on the mouth of pipe that needs to connect, and by the bolted flange dish, thereby realizes that pipeline connects.This method is a kind of the most frequently used Placement, and it connects reliable, can be used for, in the low pressure line, and flange plate is a standard piece, can be connected with equipment with the various pump housings easily, but its cost height, installation strength is big, and installation efficiency is low.
The model utility content
The purpose of this utility model provides a kind of simple in structure, good airproof performance, and pipeline fast connector easy to install.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of pipeline rapid pipe joint, and 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, sealing circle section is interior ring open type rectangle.
The quantity of described anchor ear is 2～4, is the ring of sealing when it is closed, and the internal diameter of this ring and the external diameter of connected pipe match.
Described anchor ear hoop is connected on the joint of two pipelines, and the convex edge of the end of pipeline is stretched in the circular groove of anchor ear and touched with the seal ring butt, between the pipeline end face of joint axial clearance is arranged.
Being contained in two seal rings on the pipe head has certain pretightening force in the joint, guaranteed closely to contact between seal ring and the pipeline; Connecting head described in the utility model only is made up of several parts, and is simple in structure, with low cost.
Remarkable result of the present utility model is: simple in structure, and good airproof performance, and easy to install quick.

Embodiment
As Fig. 1, Fig. 2, shown in Figure 6, the fast connector that is used for the pipeline connection mainly is made up of anchor ear 2, seal ring 3, nut 4, packing ring 5, bolt 6, and numbering 1 is a connecting tube among the figure.Annexation and structure outline between them are: the inner ring of anchor ear 2 has circular groove, and there is the connection boss at its two ends, on this boss through hole is arranged; Bolt 6 passes this through hole, and anchor ear 1 is fastenedly connected in twos, makes anchor ear form annulus; Seal ring 3 is housed in the circular groove of anchor ear 1 inner ring, and sealing circle 3 sections are interior ring open type rectangle.Described anchor ear 1 hoop is connected on the joint of two pipelines 1, and the convex edge of the end of pipeline 1 is stretched in the circular groove of anchor ear 1 and touched with seal ring 3 butts, between pipeline 1 end face of joint axial clearance is arranged.Its axial clearance is 5-15mm, can make pipeline 1 realize axial adjustment with temperature or variation in pressure.
As Fig. 2, Fig. 3 and Fig. 6, shown in Figure 7: as described in the quantity of anchor ear 1 be 2～4, when it is closed, be the ring of sealing, the external diameter of the internal diameter of this ring and connected pipe 1 matches.
When the diameter of pipeline 1 hour, only need to use two anchor ears 2 of semicircular in shape; When the diameter of connecting tube 1 is big, can use a plurality of anchor ears 2 that are fan-shaped.
The seal ring 3 that is contained in anchor ear 2 circular grooves has certain pretightening force in the joint, guaranteed closely to contact between seal ring 3 and the pipeline 1, when pipeline 1 inner fluid has pressure, fluid pressure action makes pipeline produce axial displacement at the end face of pipeline 1, can not move when the pipeline end face contacts with the toroidal cavity inwall again; Seal ring 3 outwards produces distortion all around under fluid pressure action, fit tightly with toroidal cavity with the pipe end convex edge and be in the same place, and it is tight more to fit when pressure is big more, and it is good more to seal.
The utility model can be used for the connection of bilateral pipe, three-way pipe, four-way pipe, elbow or reducer pipe etc.
During installation, seal ring 3 is enclosed within on the convex edge, end of pipeline 1, the circular groove of anchor ear 2 is aimed at seal ring 3, make a plurality of anchor ears 1 be closed into circular arc, bolt 6 is passed through hole on the anchor ear 1 two ends boss, respectively packing ring 5 and nut 4 are inserted in the outer end of bolt 6 again and tighten.If need dismounting the utility model, only need unclamp nut 4, take off bolt 6 and get final product.
