Description
Technical Field
The utility model relates to a connect, in particular to solve joint of suppressing of many varieties steel hose sub-assembly.
Background
The pressing side leakage is an important inspection link in the production link of the pipe, the production requirement of 100% airtight pressing of the steel pipe and hose assembly is met, the steel pipe and hose assembly is various, the trend of the bent pipe is irregular, the pressing angle is irregular, special equipment cannot be used universally, and great problems are brought to pressing. The pressing is an important step for detecting whether the assembly is qualified, and if the effect of the step is poor, problems are likely to occur in the subsequent loading process.
In the market, the steel tube and hose assembly is various, the trend of the bent pipe and the buckling angle are irregular, so that airtight buckling is difficult to implement, and the problem of product quality cannot be checked due to poor airtightness.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a solve the joint of suppressing of many varieties steel hose sub-assembly to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a solve joint of suppressing of many varieties steel hose sub-assembly, suppress joint, the external screw thread including the internal thread and suppress joint, its characterized in that: the internal thread is suppressed and is connected the top and be provided with first radius SR7.5 seal structure, first radius SR7.5 seal structure bottom is provided with first screw thread, the internal thread is suppressed and is connected the inside first hexagonal hole to the limit that is provided with in bottom, the external screw thread is suppressed and is connected the top inner wall and be provided with the second screw thread, the internal thread is suppressed and is connected the inside second radius SR7.5 seal structure that is provided with in top, the external screw thread is suppressed and is connected the inside second hexagonal hole to the limit that is provided with in bottom.
Preferably, the internal thread pressing joint and the external thread pressing joint are made of carbon structural steel.
The utility model discloses a technological effect and advantage:
the utility model discloses a be provided with the internal thread and suppress joint, the external screw thread and suppress the joint, improve the production requirement that 100% airtight of steel hose sub-assembly was suppressed, provide the quality guarantee to follow-up sub-assembly loading, steel hose detects that the gas tightness improves and detection range is more extensive, and the commonality is better simultaneously, can realize that other pipelines suppress the general of leaking hunting.
Drawings
Fig. 1 is the internal thread pressing joint schematic diagram of the utility model.
Fig. 2 is the external thread pressing joint schematic diagram of the present invention.
In the figure: the joint is suppressed to 1 internal thread, 2 first radius SR7.5 seal structure, 3 first screw, 4 first hexagonal to the limit hole, 5 external screw are suppressed and are connected, 6 second radius SR7.5 seal structure, 7 second screw, 8 second hexagonal to the limit hole.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a solve joint of suppressing of many varieties steel hose sub-assembly as shown in fig. 1-2, suppress joint 1, external screw thread including the internal thread and suppress joint 5, its characterized in that: the internal thread is suppressed and is connected 1 top and be provided with first radius SR7.5 seal structure 2, first radius SR7.5 seal structure 2 bottom is provided with first screw thread 3, the internal thread is suppressed and is connected 1 bottom inside and be provided with first hexagonal to limit hole 4, the internal thread is suppressed and is connected 5 top inner walls and be provided with second screw thread 7, the internal thread is suppressed and is connected 5 inside second radius SR7.5 seal structure 6 that is provided with in top, the external thread is suppressed and is connected 5 inside second hexagonal to limit hole 8 that is provided with in bottom.
Further, in the above technical solution, the internal thread pressing joint 1 and the external thread pressing joint 5 are both made of carbon structural steel.
This practical theory of operation:
referring to the attached figures 1-2 of the specification, in the pressing process, a hose part of a steel pipe assembly is tightly assembled with a pressing machine, and a steel pipe part is assembled with an internal thread pressing joint 1 and an external thread pressing joint 5, so that the pressing problem of the assembly is well solved, and meanwhile, the weight of the pressing joint is calculated according to pressing pressure, camber and parameters simulating unqualified conditions such as burst leakage and blasting. The pressure in-process is because the effect of pressurization in the twinkling of an eye, can produce one and be present in the inside power of pipe fitting, this design is pressed joint 1 with the internal thread, 5 bottoms of external screw thread pressure joint are made solid to guarantee to press the in-process and press joint 1, 5 self gravity of external screw thread pressure joint to offset the internal force that the pressurization produced in the twinkling of an eye through the internal thread, because the hose sub-assembly variety is many, the return bend trend is irregular, design this kind of joint and press, sealed framework adopts first radius SR7.5 seal structure 2, second radius SR7.5 seal structure 6. The pressure-tightness detection device is suitable for the air tightness detection of the internal thread pressure joint 1 and the external thread pressure joint 5, and greatly facilitates the pressure detection of various steel hoses.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
