Description

Technical Field

[0001] The utility model relates to the technical field of precision welded steel pipes, in particular to a precision welded steel pipe with a protection mechanism. Background Art

[0002] As we all know, precision welded steel pipe is a kind of steel pipe made by precision welding technology. This kind of steel pipe usually has the characteristics of high precision, high quality and high strength, and is used in fields requiring precise dimensions, weld quality and surface finish. Precision welded steel pipe is usually made by high-precision welding technology such as high-frequency induction welding, laser welding or electron beam welding. These pipes have important application value in industrial production and can meet various strict engineering and manufacturing requirements.

[0003] However, existing precision welded steel pipes generally do not have protective devices. When precision welded steel pipes are stored, the inner wall of the pipe is easily scratched by some solid particles. The inner wall of the pipe will produce debris due to wear, and the debris produced may contaminate the fluid, affect the quality of the fluid or cause equipment damage. Utility Model Content

[0008] In order to improve the stability, the utility model is improved in that the two limiting mechanisms are symmetrically arranged.

[0009] In order to improve the strength of the main body, the utility model is improved in that a reinforcing rib is provided inside the main body, and a plurality of the reinforcing ribs are provided, and the plurality of the reinforcing ribs are cross-arranged.

[0010] In order to facilitate the rotation of the disc, the utility model is improved in that a handle is provided on the disc, and the handle is welded to the disc.

[0011] (III) Beneficial effects

[0012] Compared with the prior art, the utility model provides a precision welded steel pipe with a protective mechanism, which has the following beneficial effects:

[0013] The precision welded steel pipe with a protective mechanism can seal the inner wall of the body through a sealing column when the body is stored, so as to prevent the inner wall of the body from being scratched due to the entry of solid particles from the outside, thereby preventing the inner wall of the pipe from being contaminated by debris caused by the friction of solid particles on the inner wall of the pipe, thereby preventing the quality of the fluid and the external equipment connected to the body from being affected.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4, a precision welded steel pipe with a protective mechanism, comprising a body 1, a sealing column 2 and a limiting mechanism 3, the sealing column 2 extends into the interior of the body 1, the sealing column 2 is connected to the body 1 through the limiting mechanism 3, the limiting mechanism 3 comprises a slot 4, a threaded column 5, a disc 6, a slide 7 and a slider 8, the slot 4 is arranged on the sealing column 2, one end of the threaded column 5 is threadedly connected to the inner wall of the slot 4, the other end of the threaded column 5 is connected to the disc 6, the slide 7 is arranged on the disc 6, one end of the slider 8 is slidably connected to the slide 7, the other end of the slider 8 abuts against the outer wall of the body 1 and extends into the sealing column 2, the limiting mechanism 3 is provided with two, this embodiment In the example, the main body 1 is a conventional precision welded steel pipe on the market, which is not described in detail here. When the main body 1 is stored, the inner wall of the main body 1 can be sealed by the sealing column 2 to prevent external solid particles from entering the inner wall of the main body 1 and scratching the inner wall of the main body 1, thereby preventing the inner wall of the pipeline from being rubbed by solid particles and causing debris to contaminate the fluid flowing on the inner wall of the main body 1, thereby preventing the quality of the fluid and the external equipment connected to the main body 1 from being affected.
