Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline detection, and particularly relates to a corrosion detector. Background Art
[0002] In galvanized or carbon steel pipelines of municipal or fire protection systems, due to the long-term presence of water in the pipelines, the microorganisms or the remaining air inside the pipelines act on the inner wall of the pipelines for a long time, resulting in corrosion. If not dealt with in time, there is a high risk of pipeline rupture and water leakage.
[0003] In the prior art, whether the pipeline is corroded is usually judged by approaching and observing, or by the color change after mixing the water in the pipeline with external powder.
[0004] For the above reasons, the utility model designs a corrosion detector, and through its feedback, maintenance personnel can clearly know the degree of internal corrosion of the pipeline, so as to judge whether it is necessary to replace or maintain the pipeline. Summary of the Invention
[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a corrosion detector. Through its feedback, maintenance personnel can clearly know the degree of internal corrosion of the pipeline, so as to judge whether it is necessary to replace or maintain the pipeline.
[0006] To achieve the above purpose, the utility model provides a corrosion detector. A plunger is arranged at the center inside a housing. A fixed sleeve is arranged on one side outside the plunger. A nylon rod is arranged inside the plunger. One side of the nylon rod is connected to a screw. An O-ring is arranged on one side outside of the plunger. A pipe thread is arranged on the outer periphery of the housing.
[0007] One end of the plunger is in close contact with the inner wall of the housing, and there is a gap for the plunger to move between the other end of the plunger and the inner wall of the housing.
[0008] The cross-sectional area of the end of the plunger in close contact with the housing is larger than that of the other end.
[0009] One side end face of the housing is made of an easily corroded material, and the end face is located on the side with a larger cross-sectional area of the plunger.
[0010] The O-ring is arranged in a groove on one side of the end of the plunger in close contact with the housing.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] In the present utility model, a plunger is arranged inside a housing. After corrosion occurs at the end of the housing, the pressure of the medium inside the pipeline can be utilized to push the plunger to axially move, thereby realizing the warning of the corrosion state inside the pipeline, without the need to judge by means such as making the medium change color by mixing drugs, improving the efficiency, accuracy, and timeliness of corrosion detection, and ensuring the maintenance and normal use of important pipelines.
[0013] In the present utility model, by arranging an opening in the middle of the plunger, the plunger can be fully inserted into the inner cavity of the housing without being affected by air pressure. The opening is blocked by a nylon rod to prevent the inner cavity of the housing from being too large, resulting in the need for more medium to enter and push the plunger after the housing is corroded. Then, the nylon rod is fixed by a screw and coated with glue to prevent medium leakage. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 is a schematic diagram of the present utility model.
[0015] Figure 2 is a schematic diagram of the present utility model installed at the pipeline to be detected.
[0016] DESCRIPTION OF THE REFERENCE NUMERALS:
[0017] 1 is the housing, 2 is the screw, 3 is the fixing sleeve, 4 is the plunger, 5 is the O-ring, 6 is the nylon rod, 7 is the pipe thread, A is the easily corroded end face, and B is the housing thread. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The present utility model will be further described in conjunction with the accompanying drawings.
[0019] See Figure 1 , the present utility model provides a corrosion detector. A plunger 4 is arranged at the center inside a housing 1. A fixing sleeve 3 is arranged on one side outside the plunger 4. A nylon rod 6 is arranged inside the plunger 4. One side of the nylon rod 6 is connected to a screw 2. An O-ring 5 is arranged on one side outside the plunger 4. A pipe thread 7 is arranged on the outer circumference of the housing 1. The function of the pipe thread 7 here is to install the detection device onto the reserved detection channel interface on the side of the pipeline to be detected.
[0020] One end of the plunger 4 is in close contact with the inner wall of the housing 1, and there is a gap between the other end of the plunger 4 and the inner wall of the housing 1 for the plunger 4 to move.
[0021] The cross-sectional area of the end of the plunger 4 in close contact with the housing 1 is larger than that of its other end.
[0022] One side end face of the housing 1 is made of an easily corroded material, and the end face is located on the side with a larger cross-sectional area relative to the plunger 4. In this way, after the end face of the housing 1 is corroded, the medium inside the pipeline flows in and pushes the plunger 4 to extend in the other direction, thereby realizing the function of alarm reminder.
[0023] The O-ring 5 is arranged in the groove on one side of the end of the plunger 4 close to the housing 1.
[0024] Working principle:
[0025] When this utility model is working, it doesn't need much debugging. Connect this detector to the pipeline to be detected through the pipe thread 7 on the outer periphery of the housing 1 from the reserved detection channel interface on the side of the pipeline. Place the easily corroded end face A of the housing 1 inside the pipeline. After the end face A is corroded under the action of corrosive gas and liquid in the pipeline, the medium in the pipeline flows into this detector. Under the action of the medium pressure, the plunger 4 is pushed in the opposite direction of the end face A until one end of the plunger 4 extends out of the housing 1 and is blocked by the fixing sleeve 3. At this time, the maintenance personnel can clearly see the protruding plunger 4 outside to judge that corrosion has occurred inside the pipeline.
[0026] Using the same principle, this detector can also only retain the housing 1 and directly install a pressure sensor at the position of the housing thread B. When the easily corroded surface A is corroded and the medium flows into the housing 1 and reaches a certain pressure, the pressure sensor immediately sends out a remote alarm signal.
[0027] The above is only the preferred embodiment of this utility model, which is only used to help understand the method and its core idea of this application. The protection scope of this utility model is not limited to the above embodiments. All technical solutions under the idea of this utility model belong to the protection scope of this utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of this utility model should also be regarded as the protection scope of this utility model.
[0028] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to this utility model.
[0029] This utility model solves the inconvenience brought by the way of detecting pipeline corrosion situation depending on the judgment of drug mixed medium in the prior art as a whole. By combining the easily corroded material set outside the detector with the movement of the internal plunger under the thrust of the medium, through the feedback of the plunger, the maintenance personnel can clearly know the degree of corrosion inside the pipeline, so as to judge whether it is necessary to replace or maintain the pipeline.
