Description

Technical Field

[0001] The utility model belongs to the technical field of reduced diameter pipes, and in particular relates to a reduced diameter pipe with adjustable pipe diameter. Background Art

[0002] A reducer, also known as a reducing nipple, is a pipe fitting used to connect two pipes of different sizes to achieve a pipe diameter change. There are two types of reducers: concentric reducers and eccentric reducers. The center lines of the two pipes connected by a concentric reducer are in a straight line and are mainly used for vertical pipelines; while eccentric reducers are more commonly used in horizontal pipelines. Reducers are widely used in pipeline engineering, especially when the diameter of the pipeline needs to be changed. For example, in small-diameter pipelines (below DN50), reducing nipples are often used instead of reducing joints to reduce the diameter of the pipeline. In addition, the coated reduced-diameter steel pipes prepared through a special process can directly install small accessories or pipes, eliminating the need for the setting of reducers, saving materials, and simplifying the structure. However, the reduced-diameter steel pipes still have the following defects: when using the reduced-diameter steel pipes for pipe docking, since the reduced-diameter steel pipes are made as one piece, after docking, the reduced-diameter steel pipes cannot control the medium being transmitted, that is, the internal diameter of the reduced-diameter steel pipes cannot be adjusted, which results in the reduced-diameter steel pipes being unable to adjust their diameters as needed during or after docking, and thus the inside of the reduced-diameter steel pipes cannot be observed and controlled. Utility Model Content

[0005] The outer side wall of the large diameter tube is connected with a connecting tube, the other end of the connecting tube is connected with an assembly block, one side of the assembly block is connected with a positioning block, the surface of the positioning block is penetrated by a rotating rod, the rotating rod extends to the inner end of the large diameter tube and is connected with a ball valve body, a first sealing ring is installed inside the connecting tube, a second sealing ring is installed inside the assembly block, a threaded rod is penetrated by the surface of the positioning block, the bottom end of the threaded rod is connected with a rotating block, the bottom surface of the rotating block is connected with a linkage plate, and the bottom surface of the linkage plate is connected with a clamping block.

[0006] In order to ensure safe use, as a preferred reducing tube with adjustable diameter of the utility model, the large diameter tube is connected to a sealing seat close to the inner wall of the ball valve body, and the sealing seat is made of rubber material.

[0007] In order to facilitate the adjustment of the medium flow rate, as a preferred reducer with adjustable diameter of the utility model, the diameter of the ball valve body is adapted to the aperture of the large diameter tube, and a through hole is opened on the same axial line as the large diameter tube.

[0008] In order to maintain sealing, as a preferred reducing tube with adjustable diameter of the utility model, the first sealing ring and the second sealing ring are both made of silicone material, and the first sealing ring and the second sealing ring are both sleeved on the surface of the rotating rod.

[0009] In order to adjust the rotating rod, as a preferred embodiment of the utility model, a reducing tube with adjustable diameter is preferably configured such that the threaded rod is threadedly connected to the positioning block, and the threaded rod is rotationally connected to the rotating block.

[0010] In order to keep the rotating rod stable, as a preferred embodiment of the utility model of a reducing tube with adjustable diameter, a groove is provided on the surface of the rotating rod, and the clamping block and the groove on the surface of the rotating rod form a chimeric structure.

[0011] Compared with the prior art, the beneficial effects of the utility model are:
