Abstract
The utility model provides a welding deformation prevention aluminum alloy RP series pipe threaded joint. An excircle of the welding deformation prevention aluminum alloy RP series pipe threaded joint is provided with a step, an inner cavity of a joint excircle, provided with a step end, is smooth, an inner cavity arranged at the other end of the joint is provided with screw threads, the diameter of a step hole is greater than the threaded large diameter of a threaded hole and is 1 RpRp greater than the threaded large diameter of the threaded hole, and the depth of the step hole is 5 RpRp greater than the step width. The threaded joint has the advantages that the structure is simple, the processing method is simple, the problem that screw threads cannot be used after the existing threaded joint is heated can be solved, and in addition, the installation is convenient.
Description
Technical field
The utility model relates to a kind of anti-welding deformation aluminum alloy RP series pipe screw joint,
Background technique
The shortcoming of prior art one is in welding process, because the Al-alloy pipe inipple can be owing to high temperature deforms, particularly dimensional changes can occur in the internal thread of joint, cause welding after joint screw thread less than the situation of standard, all need hard waste after making the pipe screw joint welding, could pass through check, work efficiency is lower, and the aluminium bits behind the hard waste come off easily at heat exchanger cavity, are not easy cleaning, stop up runner, affect heat-exchange performance and accuracy of thread and descend.
The model utility content
In order to overcome above problem, the utility model provides a kind of anti-welding deformation aluminum alloy RP series pipe screw joint, can solve the above defective, makes aluminum alloy RP series pipe screw joint in the tolerance range of welding rear thread size at standard thread.
For solving above technical problem, the utility model provides following technological scheme: a kind of anti-welding deformation aluminum alloy RP series pipe screw joint, and joint has tapped hole, and the cylindrical of described inipple has step, have step hole in this step, step width is 2RpRp.
Further, the step hole diameter is greater than the Major Diam of tapped hole.
Further, the step hole diameter is greater than the Major Diam 1RpRp of tapped hole.
Further, step hole depth is greater than step width 5RpRp.
Further, the degree of depth of step hole is 7RpRp.
Further, the roughness of step hole is 6.3.
This inipple that the utility model provides is that the size of joint internal thread is carried out suitable amplification according to the acquisition data of welding procedure test, being out of shape maximum part at the joint internal thread is that joint bottom car goes out a step hole, bore dia is greater than Major Diam 1RpRp, hole depth is that length of bench adds 5RpRp, thereby makes aluminum alloy RP series pipe screw joint in the tolerance range of welding rear thread size at standard thread.
Description of drawings
Fig. 1 is a kind of anti-welding deformation aluminum alloy of the utility model RP series pipe screw joint structural drawing;
1-cylindrical step; The 2-step hole; The 3-tapped hole.
Embodiment
As shown in Figure 1, inipple has cylindrical step 1, and inner circle has step hole 2 and tapped hole 3.
A kind of anti-welding deformation aluminum alloy RP series pipe screw joint that the utility model provides, simple in structure, processing method is simple, can solve the problem that after existing inipple is heated screw thread can't be used, the convenient installation.
Embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
