Description

Technical Field

[0001] The utility model relates to the field of connection structures, in particular to a pipeline connection structure for tap water. Background Art

[0002] At present, the Chinese utility model with the publication number of CN220186135U discloses a connection structure for tap water pipelines, which relates to the technical field of pipeline connection. It includes flange plates arranged on the adjacent end sides of two tap water pipes and fixing bolts arranged through the two flange plates. A buffer cylinder is also arranged between the two flange plates. One end of the buffer cylinder is inserted into one tap water pipe, and the other end is inserted into the other tap water pipe. A connection component is also arranged between the two flange plates for stably and sealingly connecting the tap water pipe and the buffer cylinder. This application has the effect of improving the stability of the connection of the tap water pipe, thereby improving the service life of the connection of the tap water pipe;

[0003] Although the existing pipeline connection structure can fix the two flanges through the connection component, there are still other problems in the use process. For example, the sealing effect is poor. When the flange connection is damaged by external force or the gasket ages, gaps will be generated at the flange connection. At this time, the tap water in the pipeline is likely to leak out from the flange connection, and the safety is poor. Moreover, it is not convenient to replace the flange. Either the existing flange and the pipeline are fixed by welding or by glue bonding. When the flange is damaged and needs to be replaced, the pipeline below needs to be cut off together. The cutting of the pipeline will cause the original length to become shorter, which is not conducive to subsequent repair, increasing the workload of the personnel. To solve the above problems, we propose a pipeline connection structure for tap water. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pipeline connection structure for tap water, which solves the problems that the existing pipeline connection structure has a poor sealing effect and is not convenient to replace the flange.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A pipeline connection structure for tap water includes a first reinforcing clamping plate. A second reinforcing clamping plate is placed on the top of the first reinforcing clamping plate. A first flange and a second flange are respectively clamped between the first reinforcing clamping plate and the second reinforcing clamping plate. A fixing bolt penetrates through the top of the second reinforcing clamping plate. A fixing nut cooperating with the fixing bolt is embedded at the bottom of the first reinforcing clamping plate. A clamping groove is formed on one side of the back surfaces of the first flange and the second flange. A tap water pipe is slidably sleeved inside the clamping groove. First external threaded pipes are welded on the opposite sides of the first flange and the second flange. A second external threaded pipe is fixedly sleeved on the surface of the tap water pipe. An internal threaded pipe is threadedly connected to the surface of the second external threaded pipe.

[0006] Adopting the above technical solution can facilitate the replacement of the flange, with simple and convenient operation, will not cause damage to the pipeline, reduce the workload of personnel, and at the same time can achieve good sealing and protection effects, avoid liquid leakage caused by gaps at the connection, and has high practicability.

[0007] The present utility model is further configured as: through holes are respectively provided inside the first flange and the second flange.

[0008] Adopting the above technical solution, through the arrangement of the through holes, it is convenient for personnel to fixedly connect the first flange and the second flange by means of the connecting components.

[0009] The present utility model is further configured as: a sealing ring fitting the water supply pipe is installed inside the clamping groove.

[0010] Adopting the above technical solution, through the arrangement of the sealing ring, the sealing effect between the port of the water supply pipe and the clamping groove can be improved.

[0011] The present utility model is further configured as: the surfaces of the first flange, the second flange, the first reinforcing clamping plate and the second reinforcing clamping plate are all coated with anti-corrosion paint.

[0012] Adopting the above technical solution, through the arrangement of the anti-corrosion paint, the anti-corrosion effect of the first flange, the second flange, the first reinforcing clamping plate and the second reinforcing clamping plate can be improved, and their service life can be prolonged.

[0013] The present utility model is further configured as: both the fixing bolts and the fixing nuts are made of stainless steel.

[0014] Adopting the above technical solution, the fixing bolts and the fixing nuts have the characteristics of high strength, low density and excellent corrosion resistance.

[0015] The present utility model is further configured as: the first external threaded pipe and the second external threaded pipe have the same diameter.

[0016] In summary, the present utility model has the following beneficial effects:

[0017] 1. By first picking up the first flange and the second flange and respectively sleeving them on the two water supply pipes, then pushing the first flange and the second flange inward to the end so that the first external threaded pipe fits with the second external threaded pipe, when the first external threaded pipe and the second external threaded pipe are fitted, grasping the internal threaded pipe and rotating it inward, the internal threaded pipe will move inward from the second external threaded pipe until the first external threaded pipe and the second external threaded pipe are covered, the present utility model can facilitate the replacement of the flange, with simple and convenient operation, will not cause damage to the pipeline, and reduce the workload of personnel;

[0018] 2. After the first flange and the second flange are fixed, pick up the second reinforcing clamping plate. The second reinforcing clamping plate is picked up and clamped on the upper half of the first flange and the second flange. Then pick up the first reinforcing clamping plate and clamp it on the lower half of the first flange and the second flange. When the first reinforcing clamping plate and the second reinforcing clamping plate are pushed inward to the end and fit together, pick up the fixing bolt, insert it from above the second reinforcing clamping plate and screw it into the fixing nut. This can achieve a good sealing and protection effect, avoid gaps at the connection causing liquid leakage, and has high practicality. Description of the Drawings
