Description

Corrugated thin-wall stainless steel pipe

technical field

The utility model relates to a stainless steel pipe, in particular to a corrugated thin-walled stainless steel pipe.

Background technique

Stainless steel water pipes are more and more accepted by people because of their advantages of high strength, good corrosion resistance, elegant appearance, long life, and recyclability. Thin-walled stainless steel water pipes are thin in thickness, light in weight, and low in investment and transportation It can be greatly reduced, but the connection is more difficult, and a special joint is required to connect. When the corner is turned, a combined joint is required to complete it, which is inconvenient to install. At present, the high-tightness connecting pipes with threaded pipes appearing on the market are generally used in pipelines such as automobiles and air conditioners. They are usually made of metal copper, plastic, rubber or other materials, and their function is to meet the needs of installation. Provide good expansion and contraction deformation and shockproof performance. In the prior art, the corrugated stainless steel pipe is only used in the field of stainless steel water pipes. Although it has good expansion and contraction performance and can eliminate the installation level difference, it requires many materials. Manufacturing high cost.

In response to this situation, Patent No.: 201010229054.7 provides a corrugated thin-walled stainless steel pipe, including a stainless steel pipe, a corrugated section is set on the stainless steel pipe, and the corrugated section is a raised annular spiral body with no less than three turns. , The bellows can be bent in any direction. Compared with traditional stainless steel water pipes, the use of special pipe fittings is reduced, less materials are required, and the manufacturing cost is greatly reduced. For general media, this corrugated stainless steel pipe can meet the needs and is the first choice at present. However, if the pipeline medium is The viscous substance flows to the bellows in the pipeline circulation, and the substance is contaminated to the raised ring circle of the bellows. After a long time, if it is not cleaned, it will cause blockage, and the bellows will no longer expand and contract after being blocked. If it is bent, the corrugated pipe is relatively meaningless, so it needs to be improved.

Contents of the invention

Aiming at the deficiencies in the prior art, the utility model provides a corrugated thin-walled stainless steel pipe with simple structure, convenient installation and no clogging of the corrugated pipe no matter what kind of medium it is.

The technical solution provided by the utility model is: a corrugated thin-walled stainless steel pipe, including a stainless steel pipe, the stainless steel pipe is provided with a bellows, and the bellows is a raised annular spiral body with no less than three turns. The two ends of the bellows are respectively detachably connected to the stainless steel pipe, and the joint between the bellows and the stainless steel pipe is provided with a seal.

With the above technical scheme, the bellows can be detachably connected to the stainless steel pipe, so that the bellows can be disassembled and cleaned regularly after setting, so as to avoid the bellows from clogging and maintain the flexibility or bendability of the bellows, while the connection between the bellows and the stainless steel pipes Seals are provided to prevent medium leakage.

The utility model is further set as follows: the two ends of the bellows are respectively provided with connecting pipes, the connecting pipes are provided with external threads, the connecting pipes can be sleeved in stainless steel pipes, and the stainless steel pipes are connected with corrugated pipes. The pipe is provided with an internal thread adapted to the external thread.

With the above technical solution, by setting the thread on the connecting pipe and the connecting pipe can be placed in the stainless steel pipe, after this setting, the bellows can be better connected with the stainless steel pipe, the connection method using the thread is simple, and the connection is more convenient. firm.

The utility model is further configured as follows: the sealing member is a rubber gasket, and one end of the rubber gasket is arranged between the outer wall of the connecting pipe and the inner wall of the stainless steel pipe.

Adopting the above technical scheme, the sealing effect is good, and the medium will not leak.

Below in conjunction with accompanying drawing, the utility model is further described.

Description of drawings

Fig. 1 is a schematic diagram of the overall cross-sectional structure of an embodiment of the utility model.

detailed description

A corrugated thin-walled stainless steel pipe as shown in Figure 1 includes a stainless steel pipe 1, and the stainless steel pipe 1 is provided with a bellows 2, and the bellows 2 is a raised annular spiral body with no less than three turns, The two ends of the bellows 2 are detachably connected to the stainless steel pipeline 1 respectively, and the joint between the bellows 2 and the stainless steel pipeline 1 is provided with a seal 3. In the above scheme, the bellows 2 is detachably connected to the stainless steel pipeline 1, After this setting, the bellows 2 can be disassembled regularly for cleaning to avoid the bellows 2 from clogging and maintain the flexibility or flexibility of the bellows 2. The seal 3 is set at the joint between the bellows 2 and the stainless steel pipe 1 to prevent the medium Give way.

In the embodiment of the present utility model, the two ends of the corrugated pipe 2 are respectively provided with connecting pipes 21, and the connecting pipes 21 are provided with external threads 22, and the described connecting pipes 21 can be sleeved in the stainless steel pipe 1, The stainless steel pipe 1 is connected to the bellows 2 with an internal thread 23 that is compatible with the external thread 22. In the above-mentioned scheme, by providing threads on the connecting pipe 21 and the connecting pipe 21 can be placed in the stainless steel pipe 1, such After setting, the corrugated pipe 2 can be better connected with the stainless steel pipe 1, and the thread connection method is simple, and the connection is more firm.

The utility model is further configured as follows: the sealing member 3 is a rubber gasket 31 , and one end of the rubber gasket 31 is arranged between the outer wall of the connecting pipe 21 and the inner wall of the stainless steel pipe 1 .

Adopting the above technical scheme, the sealing effect is good, and the medium will not leak.
