Description

Technical Field

[0001] The present application relates to the technical field of seal detection, and in particular, to a method and system for detecting the seal of a two-way receiving plug. Background Art

[0002] At present, socket and spigot connection is a widely used pipe connection method in industries such as water supply and drainage, gas, and chemical industry. It realizes the sealed connection of pipes by inserting the spigot into the socket and using sealing materials. This connection method is not only easy to install, but also has good sealing performance and certain flexibility, can effectively resist axial tension, and is suitable for pipes of different materials. A two-way receiving plug for pipes is a connecting component used in a pipe system, which allows fluid to flow freely in two directions, and at the same time realizes quick plugging and sealing. The core of its design is the "two-way symmetric structure", that is, the plug and the socket have the same interfaces at both ends, there is no need to distinguish the insertion direction, and it can ensure two-way sealing and stable connection. When there is a leakage in the two-way receiving plug due to seal failure, it will have an adverse impact on people's daily life. Therefore, it is crucial to detect the sealing condition of the two-way receiving plug.

[0003] The existing methods for detecting the seal of a two-way receiving plug refer to directly observing whether there are visible gaps, cracks or damages at the joint of the two-way receiving plug, or applying a dye penetrant at the joint of the two-way receiving plug, and then observing whether the dye penetrant penetrates to places outside the joint. The direct observation method and the dye penetration method in the existing methods for detecting the seal of a two-way receiving plug can only detect whether the two-way receiving plug has failed to seal and leaked, and cannot predict the risk of seal failure, and cannot process the two-way receiving plug that is about to fail to seal in advance. The accuracy of detecting the sealing condition of the two-way receiving plug is relatively low, and there is room for improvement. Summary of the Invention

[0018] The following further describes the present application in detail with reference to the drawings.

[0019] The embodiment of the present application discloses a two-way connection plug sealing detection method.

[0020] A two-way connection plug sealing detection method includes the following steps: Referring to Figure 1 , in step S1, water is injected into and pressurized in the pipeline connected to the two-way connection plug under test and pressure is maintained, and it is judged whether there is a leakage in the two-way connection plug under test to obtain the current sealing performance detection result. Step S1 specifically includes the following sub-steps: The inside of the pipeline connected to the two-way connection plug under test is purged of air, and after the purging operation is completed, the result of the completion of the preliminary preparation is output after the purging operation.

[0021] When the result of the completion of the preliminary preparation is received, a pressure gauge is installed between the pipeline connected to the two-way connection plug under test and the two-way connection plug under test, and the reading of the pressure gauge is read in real time to obtain the characteristic pressure value.

[0022] Perform a water injection operation into the pipeline connected to the two-way receiving plug to be tested, and read the pressure gauge reading. During the water injection operation, perform an exhaust operation until the pipeline connected to the two-way receiving plug to be tested is filled with water and there is no air residue, and output the result of the completion of water injection.

[0023] After receiving the result of the completion of water injection, perform a step-by-step pressurization operation on the two-way receiving plug to be tested based on a preset pressure gradient. When the pressure inside the two-way receiving plug to be tested reaches the set pressure value, keep the pressure inside the two-way receiving plug to be tested at the set pressure value for voltage stabilization based on the set voltage stabilization time.

[0024] Record the characteristic pressure values during the step-by-step pressurization operation and the voltage stabilization operation, and create a current sealing pressure change curve graph.

[0025] Based on the current sealing pressure change curve graph, determine whether there is a sudden pressure drop phenomenon, that is, within a unit time in the current sealing pressure change curve graph, the pressure change value inside the two-way receiving plug to be tested is greater than the preset unit time pressure change threshold. If there is a sudden pressure drop phenomenon, it is determined that there is a leakage situation in the two-way receiving plug to be tested currently, and output the current sealing abnormality result. If there is no sudden pressure drop phenomenon, it is determined that there is no leakage situation in the two-way receiving plug to be tested currently, and output the current sealing normal result.

[0026] The current sealing abnormality result and the current sealing normal result are combined to form the current sealing performance detection result.

[0027] Refer to Figure 1 , step S2, detect the influence of the material of the sealing ring inside the two-way receiving plug to be tested and the structural design of the two-way receiving plug to be tested on the sealing performance to obtain the material structure risk coefficient W 1 . Step S2 specifically includes the following sub-steps: Obtain a sealing ring material performance table, which includes the sealing performance and durability performance of different sealing ring materials. The durability performance refers to the average value of wear resistance, aging resistance, and corrosion resistance.

[0028] Detect the composition material of the sealing ring inside the two-way receiving plug to be tested to obtain the sealing ring material information. Based on the comparison between the sealing ring material information and the sealing ring material performance table, judge the sealing performance of the sealing ring to obtain the sealing ring sealing performance information, and judge the durability performance of the sealing ring to obtain the sealing ring durability performance information.

[0029] According to the sealing ring sealing performance information, judge the influence of the sealing performance of the sealing ring on the sealing performance of the two-way receiving plug to be tested to obtain the first sealing ring material influence coefficient AY. Among them, the better the sealing ring sealing performance information of the sealing ring inside the two-way receiving plug to be tested, the smaller the first sealing ring material influence coefficient AY.

[0032] Detect the contact area between the sealing ring and the bidirectional receiving plug to be tested to obtain the sealing surface contact area information. Based on the sealing surface contact area information, judge the influence of the contact area between the sealing ring and the pipeline on the sealing performance of the bidirectional receiving plug to be tested to obtain the second type of sealing ring material risk coefficient AM. Among them, the larger the sealing surface contact area information, the smaller the sealing surface contact risk coefficient AM. In actual use, the larger the contact area of the sealing surface, the better the sealing performance usually is.

[0033] Based on the first type of sealing ring material risk coefficient AC and the second type of sealing ring material risk coefficient AM, according to the second sealing ring material relationship function Perform calculations to obtain the sealing ring material risk coefficient AKR, where a3 and a4 are proportionality factors and are both greater than 0.

[0034] Step S2 further includes the following sub-steps: Measure the compression deformation amount of the sealing ring after the bidirectional receiving plug to be tested is inserted to obtain the sealing ring compression deformation amount information. Based on the sealing ring compression deformation amount information, obtain the sealing ring compression rate. Based on the sealing ring compression rate, judge the influence of the deformation amount of the sealing ring after the bidirectional receiving plug to be tested is inserted on the sealing performance of the bidirectional receiving plug to be tested to obtain the compression rate risk coefficient BR.

[0035] In actual use, when the sealing ring is inserted into the bidirectional receiving plug to be tested, insufficient compression will cause leakage, and excessive compression will accelerate aging.

[0036] Specifically, compare the sealing ring compression rate with the preset sealing ring compression rate standard range. If the sealing ring compression rate is within the preset sealing ring compression rate standard range, it indicates that the deformation amount of the sealing ring after the bidirectional receiving plug to be tested is inserted does not affect the sealing performance of the bidirectional receiving plug to be tested, and the compression rate risk coefficient BR is obtained as 0.

[0037] If the compression rate of the sealing ring is not within the preset standard range of the sealing ring compression rate, it indicates that the deformation of the sealing ring after the bidirectional receiving plug to be tested is inserted affects the sealing performance of the bidirectional receiving plug to be tested. Calculate the minimum difference between the compression rate of the sealing ring and the preset standard range of the sealing ring compression rate to obtain the compression rate difference of the sealing ring, and obtain the compression rate risk coefficient BR based on the compression rate difference of the sealing ring. Among them, the larger the compression rate difference of the sealing ring, the larger the compression rate risk coefficient BR.

[0038] Detect the tightening force of the locking mechanism that locks the bidirectional receiving plug to be tested to obtain the mechanism tightening force information, and judge the influence of the locking mechanism on the sealing performance of the bidirectional receiving plug to be tested based on the mechanism tightening force information to obtain the locking risk coefficient BS. Among them, the greater the tightening force in the mechanism tightening force information, the smaller the locking risk coefficient BS.

[0039] Detect the alignment degree between the bidirectional receiving plug to be tested and the pipeline to obtain the plug alignment degree, and judge the influence of the alignment degree between the bidirectional receiving plug to be tested and the pipeline on the sealing performance of the bidirectional receiving plug to be tested to obtain the alignment degree risk coefficient BQ.

[0040] Specifically, compare the plug alignment degree with the preset plug alignment degree threshold. If the plug alignment degree is greater than or equal to the preset plug alignment degree threshold, it is judged that the alignment degree between the bidirectional receiving plug to be tested and the pipeline has no influence on the sealing performance of the bidirectional receiving plug to be tested, and the alignment degree risk coefficient BQ is obtained as 0.

[0041] If the plug alignment degree is less than the preset plug alignment degree threshold, it is judged that the alignment degree between the bidirectional receiving plug to be tested and the pipeline has an influence on the sealing performance of the bidirectional receiving plug to be tested. Calculate the difference between the plug alignment degree and the preset plug alignment degree threshold to obtain the plug alignment degree difference, and obtain the alignment degree risk coefficient BQ based on the plug alignment degree difference. Among them, the larger the plug alignment degree difference, the larger the alignment degree risk coefficient BQ.

[0042] According to the compression rate risk coefficient BR, the locking risk coefficient BS, and the alignment degree risk coefficient BQ, based on the structural design relationship function perform calculations to obtain the structural design risk coefficient BJK, where b1, b2, and b3 are proportionality factors and are all greater than 0.

[0044] Refer to Figure 1 In step S3, the influence of the installation and use of the bidirectional receiving plug to be tested on the sealing performance of the bidirectional receiving plug to be tested is detected to obtain the installation and use risk coefficient W 2 . Step S3 specifically includes the following sub-steps: Obtain the historical usage information of the bidirectional receiving plug to be tested, where the historical usage information includes historical usage duration information and historical insertion and extraction frequency information.

[0045] Based on the historical usage duration information of the bidirectional receiving plug to be tested, judge the influence of the usage duration on the sealing performance of the bidirectional receiving plug to be tested in the historical usage situation to obtain the historical usage duration risk coefficient CL. Among them, the longer the historical usage duration information of the bidirectional receiving plug to be tested, the greater the historical usage duration risk coefficient CL.

[0046] Based on the historical insertion and extraction frequency information of the bidirectional receiving plug to be tested, judge the influence of the insertion and extraction frequency on the sealing performance of the bidirectional receiving plug to be tested in the historical usage situation to obtain the historical insertion and extraction frequency risk coefficient CP. Among them, the higher the historical insertion and extraction frequency information of the bidirectional receiving plug to be tested, the greater the historical insertion and extraction frequency risk coefficient CP.

[0047] Detect the insertion and extraction force each time the bidirectional receiving plug to be tested is inserted to obtain multiple insertion and extraction force information, judge whether the insertion and extraction force of the bidirectional receiving plug to be tested is within a reasonable range each time it is inserted based on each insertion and extraction force information, and output the insertion and extraction force risk coefficient CB.

[0048] In actual use, too large an insertion and extraction force will wear the sealing ring, and too small an insertion and extraction force will cause the sealing ring to be not firmly locked.

[0049] Specifically, compare multiple insertion and extraction force information with the preset insertion and extraction force standard range. If the insertion and extraction force information is within the preset insertion and extraction force standard range, it is determined that the insertion and extraction force of the bidirectional receiving plug to be tested is reasonable, and the insertion and extraction force risk coefficient CB is output as 0.
