Technical Field

[0001] The utility model relates to the technical field of drinking water pipelines, especially stainless steel pipelines for drinking water. Background Art

[0002] Using stainless steel pipelines to transport drinking water is a widely used method, because it has various advantages to ensure water quality safety and the durability of the pipelines. Stainless steel pipelines play an important role in daily life. The number of pipelines required for the water supply system is large, and assembly and connection at the ends are needed. Common stainless steel pipes are connected using external flanges, and under the action of the connecting flanges, the purpose of sealing the ends of the stainless steel pipes is achieved.

[0003] However, for common stainless steel pipelines for drinking water, usually only butt joint is required during connection at the ends, resulting in reduced sealing performance at the connection of the stainless steel pipes. It is easy to infiltrate water into the flange during water conduction, thus eroding the flange and reducing its sealing effect. In view of this, we propose a stainless steel pipeline for drinking water. Summary of the Utility Model

[0004] The purpose of the utility model is to propose a stainless steel pipeline for drinking water aiming at the problems existing in the background art.

[0005] The technical solution of the utility model: A stainless steel pipeline for drinking water, including a stainless steel pipe body. A ring-shaped sealing kit for blocking and sealing is sleeved on the outer surface of the stainless steel pipe body. A sealing component for facilitating the sealing of the interface of the stainless steel pipe body is arranged between the ring-shaped sealing kit and the stainless steel pipe body. The sealing component includes an in-pipe sealing cylinder. A blocking and sealing collar is sleeved on the outer surface of the in-pipe sealing cylinder. A movable positioning sleeve is connected to the outer wall of the in-pipe sealing cylinder. Positioning components for assisting in positioning the sealing component are symmetrically arranged in the stainless steel pipe body. The positioning components include positioning insertion rods, and magnet blocks are sleeved on the outer surfaces of the positioning insertion rods.

[0006] Preferably, the blocking and sealing collar is located inside the ring-shaped sealing kit. The outer surface of the blocking and sealing collar is in close contact with the inner surface of the ring-shaped sealing kit, and the outer surface of the blocking and sealing collar and the inner surface of the ring-shaped sealing kit are arranged in a non-fixed connection state.

[0007] Preferably, a part of the structure of the in-pipe sealing cylinder is inserted into the stainless steel pipe body, and the two movable positioning sleeves are symmetrically installed on the outer wall of the in-pipe sealing cylinder.

[0008] Preferably, first sliding grooves, second sliding grooves and a rotating groove are formed on the inner wall of the stainless steel pipe body. The first sliding groove and the second sliding groove are both communicated with the rotating groove.

[0009] Preferably, one side openings of the two first sliding grooves are located at the interface end of the stainless steel pipe body, and the two movable positioning sleeves respectively penetrate through the first sliding grooves corresponding in position.

[0010] Preferably, one end of the positioning insertion rod is connected to the inner wall of the second sliding groove corresponding in position, and the magnet block is also arranged in the second sliding groove corresponding in position.

[0011] Preferably, a plurality of the second sliding grooves are symmetrically arranged on both side walls of the rotating groove, and the positions of the second sliding grooves are staggered from the positions of the first sliding grooves.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] The sleeving of the annular sealing kit of the utility model makes the inner ring surface of the annular sealing kit closely adhere to the outer ring surface of the blocking sealing sleeve ring, and places the blocking sealing sleeve ring in the annular sealing kit, which is convenient for placing the port of the stainless steel pipe body docked with it in the annular sealing kit during the connection process of the stainless steel pipe body, and cooperates with the blocking sealing sleeve ring to seal its end. At the same time, part of the structure of the inner sealing cylinder in the pipeline is inserted into the internal of the docked stainless steel pipe body, further improving the sealing performance of the stainless steel pipe body during the connection process, reducing the risk of water seepage at the splicing part, preventing the erosion of the existing flange fixing parts, and under the action of the first sliding groove in the stainless steel pipe body, the movable positioning sleeve can be guided into the rotating groove tightly. At the same time, by rotating the inner sealing cylinder in the pipeline to adjust the position of the movable positioning sleeve, the position of the movable positioning sleeve corresponds to the position of the second sliding groove. At this time, pulling the inner sealing cylinder in the pipeline can drive the movable positioning sleeve to insert onto the positioning insertion rod corresponding in position, and use the magnet block corresponding in position to magnetically attract the movable positioning sleeve to limit the position of the sealing component. Reversing the rotation adjusts the movable positioning sleeve to correspond to the position of the first sliding groove, and the sealing component can be quickly disassembled, which is beneficial to replace it according to its usage and wear conditions to prevent affecting the subsequent sealing performance.
