いる。Such a threaded joint device is disclosed in West German Patent Publication No. 2623157.
It is known as No. In order to prevent expansion of the threaded joint body or the threaded joint pipe, the intermediate ring of this known device is arranged at right angles to the axis behind the large diameter end of the conical surface facing towards the threaded joint pipe. It has an annular stop surface that cooperates with the end.

組立費が生じる。そハＬ。However, in one of the embodiments shown therein, the end of the intermediate ring does not directly contact the internal stepped surface f of the threaded joint tube, so that an annular groove is formed, which facilitates the flow of fluid within the joint. The disadvantage is that turbulence occurs and the flow conditions are adversely affected. Furthermore, in order to achieve a sufficient seal, at least one annular groove 11 is provided on the outer conical surface of the intermediate ring to receive the OIJ groove.
The disadvantage is that it has to be marketed. If the sealing requirements are high, it will be necessary to compensate for QIJ and packing, but this will result in additional costs and assembly costs. Soha L.

がか＼る。S- Plastic or rubber O-rings cannot be used as joints for fluids that are exposed to high temperatures or corrode the material of the O-ring when used as a backing. Also, because the intermediate ring is not made to prevent loss along with the joint pipe, it takes time to disassemble the connection.

円筒形で、内周が中心に向かって厚くなって居り。This is to prevent the intermediate ring from being lost. However, the intermediate ring is either welded to the threaded joint pipe or connected by engaging the deformable butt of the intermediate ring into an annular retaining groove formed by undercutting the inner circumference of the threaded joint pipe. be. In particular, the buttock of the intermediate ring originally had a cylindrical outer circumference, and the inner circumference became thicker toward the center.

要がある。To connect to a threaded joint pipe, insert it into the pipe and fit it into the engagement groove at the buttock, then push it into the intermediate ring with a tool, bend it outward with the tool at the butt that extends from the inner periphery, and tighten the retaining groove. It must be engaged inside. In fact, regardless of whether or not you can successfully bend the buttock outward with a tool to completely engage the engagement groove, it is a good idea to machine the engagement groove in the threaded joint pipe. At the same time, it is necessary to prepare a special tool to push it into the buttock retaining groove.

る。The purpose is to provide the intermediate ring with one or several deformable butts following an annular groove at the small diameter end of the conical surface facing towards the threaded joint tube in the connected state, extending radially around the radius of the butt. ST-7- The annular groove is designed to have dimensions that are larger than the radius of the cylindrical hole of the threaded joint pipe between the pad surface and the conical hole, and the sealing groove is deformed and pushed into the groove during connection. It can be solved by doing.

It may be formed into a deformable unevenness extending in the axial direction by V-cutting. Of course, the radius of the intermediate ring in the low-knot region is greater than the radius of the cylindrical bore between the radially extending stop face of the threaded joint tube and the conical bore. Furthermore, it is advantageous to fit a solder ring onto the stop face of the threaded joint tube before connection and to melt the solder after connection, so that there is a perfect metal connection between the intermediate ring and the conical bore of the threaded connection tube.

きないと共に、ごみもたまらない。The deformation of the sealing valley l of the intermediate ring pushed into the cylindrical hole 7 of the threaded joint pipe not only serves as a metal backing for high pressure and maximum pressure, but also prevents it from being lost in the threaded joint pipe. It is useful to connect to. And since there is no need for plastic or rubber QIJ packing or backing, this coupling device is especially suitable for plastic or rubber
Suitable for piping that runs through high temperatures or corrosive substances where /- cannot be used. Moreover, the axial metal connection assisted by a metal backing between the gable-shaped end face 1 and the stop face 5 results in a vibration-resistant joint. Further 1, for example, cone angle 24
The conical surface 3 of the intermediate ring (3) prevents the conical hole (2) from being reduced in cross section during connection. Therefore, bending or unintended deformation cannot occur. Furthermore, the conical surfaces 3 and 25 of the intermediate ring/
Guarantees concentric interlock. Connecting nut/3
The trumpet-shaped extension /lI on the left end of the inner periphery of the intermediate ring / which faces towards allows the fluid to flow smoothly, so turbulence does not occur and dirt does not accumulate.
