Description

Heterogeneous welding structure of cavity pipe fittings

The present invention relates to a heterogeneous welding structure for cavity pipe fittings, and more particularly to a structure for fixing cavity and pipe fittings by using heterogeneous welding.

Whether in the medical, food processing, chemical and other industries, it is necessary to use cavities and pipes to transport various gases or liquids. The conventional cavity pipe structure, if you want to join two pipes with different materials, generally The two stainless steel joints of the two pipe fittings are connected, and at least one gasket with good ductility is placed between the joints, and then the joints of the two pipe fittings are clamped by the grooves of the outer cover, and finally, screws are used to penetrate the holes of the outer cover and the joints. Reuse the nut lock to achieve the effect of fixing the pipe of different materials. In addition, when the nut is locked, because there is at least one gasket with good ductility between the two joints, when the two joints are squeezed against each other, The extension of the gasket can make the pipe formed by the joining of the two pipes vacuum, which can produce a sealing effect and avoid gas or liquid leakage.

However, the traditional technique uses a cover to close the pipe fittings of different materials, which is a stacked bed frame house. It is not only necessary to add another adapter to join the cavity and pipe fittings of different materials, which complicates the work and consumes labor. When the gas or liquid passes through the pipeline, the vibration or shaking caused by the cover or screws will easily loosen, which will cause the gas or liquid to leak. In addition, in order to detect the gaps or cracks in the pipe, all screws must be removed. Examine them one by one, and then lock them after confirming that there is no problem. Frequent loading and unloading will damage the original intact pipe fittings and reduce the service life of the pipe structure.

In view of this, the conventional cavity pipe fittings of different material joint structures do need to be improved. The inventors have conceived a heterogeneous welding structure of cavity pipe fittings through years of experience in research and development and manufacturing of related industries, in order to improve economic benefits. .

The main purpose of the present invention is to provide a heterogeneous welding structure for cavity pipe fittings, which overcomes the problem of high production costs caused by the conventional joining methods of different material pipe fittings, and can also solve the lack of frequent fitting and disassembly of pipe fittings, leading to a reduction in service life.

In order to achieve the foregoing object, the present invention provides a heterogeneous welding structure of a cavity pipe fitting, comprising: a cavity, the cavity made of a first material, including at least one pipe body and an accommodation space; a pipe piece, the pipe piece is It is made of the second material of the first material and includes at least one pipe body and a joint, and the joint is provided with a plurality of holes for screw insertion; a heterogeneous welding place is located between the first material pipe body and the first material Junction of two material pipe bodies.

With the above, one of the effects achieved by the present invention is that the cavity can be directly fixed to a pipe member of a different material, and the pipe member of another material is connected to another pipe member connected to the cavity to form a pipe for gas transportation. Or liquid, thus eliminating the need to know the different material joint structure of the cavity pipe fittings, which additionally needs to increase the production cost of the adapter and simplify the redundant and redundant joint work.

By the above, the second effect of the present invention is achieved, which can overcome the problem of gas or liquid leakage caused by loosening of the outer cover or screw of the conventional cavity pipe fittings with different material joint structures, and further solve the related inspection personnel when gas or liquid leakage The labor cost and the frequent loading and unloading of pipe fittings lead to the disadvantages of reducing the service life of the pipe structure.
