Problems solved by technology

[0002] With the large-scale use of reducers in pipeline construction, eccentric reducers have also been used in large quantities. The eccentricity of eccentric pipes in the prior art will not change, but the eccentricity cannot be particularly accurate when pipelines are connected. , it will cause great inconvenience to the connection of different-diameter pipes. If the pipes are rigidly connected together through different-diameter pipes, it is easy to cause leakage at the joint of the pipes, and it will affect the service life of the pipes. To solve the above problems, this design invention

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] It should be noted that when a component is said to be "mounted on" another component, it may be directly on the other component or there may be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly fixed to the other component or there may ...

Abstract

The invention relates to a reducing pipe. The reducing pipe comprises a large-diameter pipe body and a small-diameter pipe body which are connected with each other, the reducing pipe further comprises an end cover and a rotating disc, the small-diameter pipe body is eccentrically connected to the rotating disc, the rotating disc is rotatably connected to the end of the large-diameter pipe body so that the large-diameter pipe body can communicates with the small-diameter pipe body, the end cover covers the rotating disc and is fixedly connected with the large-diameter pipe body, and the distance between the axis of the large-diameter pipe body and the axis of the small-diameter pipe body can be adjusted by rotating the rotating disc. The reducing pipe has the advantages that the eccentric rotating disc and the small-diameter pipe body are used in cooperation, the eccentric distance between the large-diameter pipe body and the small-diameter pipe body can be changed by rotating the rotating disc, the reducing pipe can be better connected with an oil pipe by changing the eccentric distance, and pipeline distortion is avoided; and a worm part and an annular worm gear are matched to control the rotating disc to rotate, so that the eccentric distance is changed, and operation is easy and fast.

Description

technical field [0001] The invention relates to the technical field of pipe fittings, in particular to a reducing pipe. Background technique [0002] With the large-scale use of reducers in pipeline construction, eccentric reducers have also been used in large quantities. The eccentricity of eccentric pipes in the prior art will not change, but the eccentricity cannot be particularly accurate when pipelines are connected. , it will cause great inconvenience to the connection of different-diameter pipes. If the pipes are rigidly connected together through different-diameter pipes, it is easy to cause leakage at the joint of the pipes, and it will affect the service life of the pipes. To solve the above problems, this design invention. Contents of the invention [0003] Based on this, it is necessary to provide a reducer that can change the eccentricity to solve the above problems. [0004] The invention discloses a reducer, which includes a large-diameter tube and a small...
