Description
Technical Field
The utility model relates to a connect, especially relate to a copy forest connects for pipe connection.
Background
As shown in fig. 1, the copy forest joint is a stainless steel pipe connection, typically comprising three parts: clamp shell 1, seal cover 2, the both ends of clamp shell 1 are fixed through bolt and nut 3. During the use, the clamp shell 1 is all stretched into to the end of preceding pipeline and the head end of next pipeline in, places seal cover 2 at clamp shell 1 inboard simultaneously, plays the sealed effect when the pipeline communicates, and joint department adopts the design of flat mouthful type, utilizes the fit clearance of joint key shoulder and pipeline to reach the requirement of kneading nature, under the prerequisite of proof strength, connects the incomplete chucking pipeline, allows to have partial axial and radial displacement. The vibration isolation device has the characteristics of rapidness, simplicity, reliability, economy, vibration isolation and small occupied space.
In actual use, for example, an opening is formed in the side face of a certain pipeline, the opening is connected with another pipeline, and the joint can be welded and fixed through a copy joint, so that the joint 4 shown in fig. 2 can be frequently matched, one end of the joint 4 is matched with the clamp shell 1 and fixed at the clamp shell 1, and the other end of the joint is welded and fixed or screwed with the opening of the pipeline.
The connection joint 4 is generally a flat joint. When welding is used for fixing, the connecting joint 4 is directly welded with an opening on the side surface of the pipeline 5 in a contact mode, but leakage is easy to occur at the welding weak position, as shown in fig. 3, the common treatment mode is that the plane joint extends into the opening for a little distance, so that the hole can be welded along the outer circle of the plane joint 3, the plane joint 3 is firmly welded with the hole, but the extending part of the plane joint 3 can obstruct fluid transmission in the pipeline.
SUMMERY OF THE UTILITY MODEL
The utility model provides a copy forest joint, which solves the problem that when the copy forest joint of metal is welded and fixed with a metal pipeline, the joint influences the fluid transportation in the pipeline; and when the joint is welded with the pipeline, the leakage problem is easily caused due to improper welding, and the technical scheme is as follows:
a copying forest joint comprises a hoop shell, a sealing sleeve and a connecting joint, wherein two ends of the hoop shell are fixed through bolts and nuts; the other end is provided with a notch, the central line of the connecting joint extends towards the notch direction, an arbitrary straight line perpendicular to the central line is made at a certain point which is L-length away from the connecting joint, the straight line is taken as an axis, the distance from the straight line to the edge of the notch is taken as a radius R to form a cylinder, the overlapped part of the cylinder and the connecting joint is removed, and the notch is formed on the connecting joint.
The notch is in a symmetrical shape, and the symmetrical plane of the notch is a plane where the center line of the connecting joint and the two straight lines of the straight line are located.
The shape and size of the notch are matched with those of the opening on the side surface of the pipeline, the arbitrary straight line is the central line of the pipeline, and the radius R is the radius of the pipeline.
The copy forest connects and sets the contact surface through connecting joint to the shape of a saddle for its trompil form fit with the pipeline can reduce the welding degree of difficulty, improves welding quality, reduces the influence that connects fluid transport in to the pipeline, strengthens joint strength, is of value to the operation of pipeline place system.

Detailed Description
As shown in fig. 4 and 5, the connecting joint 4 is cylindrical, and one end of the connecting joint is provided with a groove 6 for being matched and fixed with a hoop shell; the other end is provided with a gap 7.
The central line of the connecting joint 4 extends towards the gap 7, an arbitrary straight line perpendicular to the central line is made at a certain point which is L-shaped from the connecting joint 4, the straight line is taken as an axis, the distance from the straight line to the edge of the gap 7 is taken as a radius R, a cylinder is formed, the overlapped part of the cylinder and the connecting joint 4 is removed, and the gap 7 is formed on the connecting joint 4.
At this time, R is greater than L.
The notch 7 is symmetrical, and the symmetrical plane is the plane where the center line of the connecting joint 4 and the two straight lines are located.
When in use, the arbitrary straight line is the center line of the pipeline 5, and the radius R is the radius of the pipeline 5.
The notch 7 needs to be matched with the shape and size of the opening edge of the pipeline 5, the flow area of the notch 7 is the same as that of the opening, or the flow area of the notch 7 is not smaller than that of the opening. From the side observation of attach fitting 4, breach 7 is the arc, curved radian is the same with pipeline 5 for the trompil shape phase-match of 5 sides of breach 7's shape and pipeline can guarantee that attach fitting does not influence the fluid transport in the pipeline 5 when the welding machine is fixed, and the welded smoothness has also been guaranteed to the shape of matching.
The copy forest connects and sets the contact surface through connecting joint to the shape of a saddle for its trompil form fit with the pipeline can reduce the welding degree of difficulty, improves welding quality, reduces the influence that connects fluid transport in to the pipeline, strengthens joint strength, is of value to the operation of pipeline place system.
