Description

Technical Field

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

[0002] At present, the socket connection is a pipe connection method widely used in water supply and drainage, gas, chemical industry and other industries. It is achieved by inserting the socket into the socket and using sealing materials to achieve a sealed connection of the pipe. This connection method is not only easy to install, but also has good sealing performance and a certain degree of flexibility. It can effectively resist axial tension and is suitable for pipes of different materials. The pipe two-way socket plug is a connection component used in pipeline systems, which allows fluids to flow freely in two directions while achieving quick plugging and unplugging and sealing. The core of its design is the "two-way symmetrical structure", that is, the plug and socket have the same interface at both ends, there is no need to distinguish the insertion direction, and it can ensure two-way sealing and a stable connection. When the seal of the two-way socket plug fails and there is a leakage, it will have an adverse impact on people's daily life. Therefore, it is very important to detect the sealing condition of the two-way socket plug.

[0003] The existing two-way socket plug sealing detection method refers to directly observing whether there are visible gaps, cracks or damages at the joints of the two-way socket plug, or applying dye to the joints of the two-way socket plug, and then observing whether the dye has penetrated into places outside the joints. The direct observation method and dye penetration method in the existing two-way socket plug sealing detection method can only detect whether the two-way socket plug has failed to seal and leaks. It cannot predict the risk of sealing failure, and cannot deal with the two-way socket plug that is about to fail to seal in advance. The accuracy of the sealing condition detection of the two-way socket plug is low, and there is room for improvement. Summary of the Invention

[0061] The present application is further described in detail below with reference to the accompanying drawings.

[0062] The embodiment of the present application discloses a method for detecting the sealing of a bidirectional socket plug.

[0063] A method for detecting the sealing of a two-way connecting plug comprises the following steps:

[0064] Reference Figure 1In step S1, water is injected into the pipe connected to the two-way socket to be tested to increase pressure and maintain the pressure, and the two-way socket to be tested is judged to determine whether there is leakage and obtain the current sealing performance test result. Step S1 specifically includes the following sub-steps:

[0065] Perform exhaust treatment on the inside of the pipe connected to the two-way socket to be tested, and output the result of completion of preliminary preparation after the exhaust treatment is completed.

[0066] After receiving the result of the completion of the preliminary preparation, a pressure gauge is installed between the pipeline connected to the two-way socket to be tested and the two-way socket to be tested, and the reading of the pressure gauge is read in real time to obtain the characteristic pressure value.

[0067] Fill the pipe connected to the two-way socket to be tested with water and read the pressure gauge reading. Simultaneously, perform exhaust operation until the pipe connected to the two-way socket to be tested is full of water and no air remains. Output the result of water filling completion.

[0068] After receiving the result of water injection completion, the two-way socket plug to be tested is gradually pressurized based on the preset pressure gradient. When the pressure inside the two-way socket plug to be tested reaches the set pressure value, the pressure inside the two-way socket plug to be tested is maintained at the set pressure value for stabilization based on the set pressure stabilization time.

[0069] Record characteristic pressure values during the gradual pressurization operation and the pressure stabilization operation, and create a current sealing pressure change curve.

[0070] Based on the current sealing pressure change curve, determine whether there is a sudden pressure drop phenomenon, that is, within the unit time in the current sealing pressure change curve, the pressure change value in the two-way socket 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 the two-way socket plug to be tested currently has a leakage, and the current abnormal sealing result is output. If there is no sudden pressure drop phenomenon, it is determined that the two-way socket plug to be tested currently has no leakage, and the current normal sealing result is output.

[0071] The current abnormal sealing result and the current normal sealing result are combined to form the current sealing performance test result.

[0072] Reference Figure 1 Step S2 is to detect the influence of the material of the sealing ring inside the two-way socket plug to be tested and the structural design of the two-way socket plug to be tested on the sealing performance to obtain the material structure risk coefficient W1. Step S2 specifically includes the following sub-steps:

[0073] Obtain a seal material performance table, which includes the sealing performance and durability of different seal materials. Durability refers to the average value of wear resistance, aging resistance, and corrosion resistance.

[0074] The material composition of the internal sealing ring of the two-way socket to be tested is detected to obtain sealing ring material information. Based on the sealing ring material information, the sealing performance of the sealing ring is compared with the sealing ring material performance table to obtain sealing ring sealing performance information, and the durability of the sealing ring is determined to obtain sealing ring durability performance information.

[0075] The influence of the sealing performance of the sealing ring on the sealing performance of the two-way socket to be tested is determined based on the sealing performance information of the sealing ring to obtain a first sealing ring material influence coefficient AY. The better the sealing performance information of the sealing ring in the two-way socket to be tested, the smaller the first sealing ring material influence coefficient AY.

[0076] The influence of the durability of the sealing ring on the sealing performance of the two-way socket to be tested is determined based on the sealing ring durability information to obtain a second sealing ring material influence coefficient AE. The better the sealing ring durability information of the sealing ring in the two-way socket to be tested, the smaller the second sealing ring material influence coefficient AE.

[0077] Based on the first sealing ring material influence coefficient AY and the second sealing ring material influence coefficient AE, according to the first sealing ring material relationship function The risk coefficient AC of the first type of sealing ring material is calculated, where a1 and a2 are proportional factors and are both greater than 0.

[0078] The contact area between the sealing ring and the two-way socket under test is measured to obtain sealing surface contact area information. Based on this sealing surface contact area information, the impact of the contact area between the sealing ring and the pipe on the sealing performance of the two-way socket under test is determined to obtain the second-category sealing ring material risk factor AM. The larger the sealing surface contact area information, the smaller the sealing surface contact risk factor AM. In actual application, a larger sealing surface contact area generally indicates better sealing performance.

[0079] According to the risk coefficient AC of the first type of sealing ring material and the risk coefficient AM of the second type of sealing ring material, based on the relationship function of the second sealing ring material The sealing ring material risk coefficient AKR is calculated, where a3 and a4 are proportional factors and are both greater than 0.

[0080] Step S2 also includes the following sub-steps:

[0081] Measure the compression deformation of the sealing ring after the two-way socket plug to be tested is inserted to obtain the compression deformation information of the sealing ring, obtain the compression rate of the sealing ring based on the compression deformation information of the sealing ring, and judge the influence of the deformation of the sealing ring after the two-way socket plug to be tested is inserted on the sealing performance of the two-way socket plug to be tested based on the compression rate of the sealing ring to obtain the compression rate risk coefficient BR.

[0082] In actual use, when the sealing ring is inserted into the two-way socket plug to be tested, insufficient compression will cause leakage, and excessive compression will accelerate aging.

[0083] Specifically, the compression rate of the sealing ring is compared with the preset standard range of the sealing ring compression rate. If the compression rate of the sealing ring is within the preset standard range of the sealing ring compression rate, it indicates that the deformation of the sealing ring after the two-way socket plug to be tested is inserted does not affect the sealing performance of the two-way socket plug to be tested, and the compression rate risk coefficient BR is 0.

[0084] If the sealing ring compression rate is not within the preset sealing ring compression rate standard range, it indicates that the deformation of the sealing ring after the two-way socket plug to be tested is inserted affects the sealing performance of the two-way socket plug to be tested. The minimum difference between the sealing ring compression rate and the preset sealing ring compression rate standard range is calculated to obtain the sealing ring compression rate difference. The compression rate risk coefficient BR is obtained based on the sealing ring compression rate difference. Among them, the greater the sealing ring compression rate difference, the greater the compression rate risk coefficient BR.

[0085] The fastening force of the locking mechanism used to lock the two-way socket plug under test is detected to obtain mechanism fastening force information. Based on the mechanism fastening force information, the impact of the locking mechanism on the sealing performance of the two-way socket plug under test is determined to obtain a locking risk coefficient (BS). The greater the fastening force in the mechanism fastening force information, the smaller the locking risk coefficient (BS).

[0086] The alignment degree between the two-way socket plug to be tested and the pipeline is detected to obtain the plug alignment degree, and the influence of the alignment degree between the two-way socket plug to be tested and the pipeline on the sealing performance of the two-way socket plug to be tested is judged based on the plug alignment degree to obtain the alignment risk coefficient BQ.

[0087] Specifically, the plug alignment is compared with the preset plug alignment threshold. If the plug alignment is greater than or equal to the preset plug alignment threshold, it is determined that the alignment between the bidirectional socket plug to be tested and the pipeline has no effect on the sealing performance of the bidirectional socket plug to be tested, and the alignment risk coefficient BQ is 0.

[0088] If the plug alignment is less than the preset plug alignment threshold, it is judged that the alignment between the bidirectional socket plug to be tested and the pipeline has an impact on the sealing performance of the bidirectional socket plug to be tested, and the difference between the plug alignment and the preset plug alignment threshold is calculated to obtain the plug alignment difference. Based on the plug alignment difference, the alignment risk coefficient BQ is obtained, wherein the greater the plug alignment difference, the greater the alignment risk coefficient BQ.

[0089] According to the compression risk factor BR, locking risk factor BS and alignment risk factor BQ, based on the structural design relationship function The structural design risk coefficient BJK is calculated, where b1, b2, and b3 are proportional factors and are all greater than 0.

[0090] According to the sealing ring material risk factor AKR and the structural design risk factor BJK, based on the material structure relationship function Calculate and determine the influence of the material of the sealing ring inside the two-way socket plug to be tested and the structural design of the two-way socket plug to be tested on the sealing performance to obtain the material structure risk coefficient W1, where: 、 are scaling factors and are all greater than 0.

[0091] Reference Figure 1 In step S3, the effect of the installation and use of the two-way socket to be tested on the sealing performance of the two-way socket to be tested is detected to obtain the installation and use risk coefficient W2. Step S3 specifically includes the following sub-steps:

[0092] Obtain historical usage information of the bidirectional socket to be tested, including historical usage duration information and historical plugging and unplugging frequency information.

[0093] Based on the historical usage time information of the two-way socket plug to be tested, the impact of the usage time in historical usage on the sealing performance of the two-way socket plug to be tested is determined to obtain a historical usage time risk coefficient CL. The longer the historical usage time information of the two-way socket plug to be tested, the greater the historical usage time risk coefficient CL.

[0094] Based on the historical plugging and unplugging frequency information of the bidirectional socket to be tested, the impact of the plugging and unplugging frequency in historical usage on the sealing performance of the bidirectional socket to be tested is determined to obtain a historical plugging and unplugging frequency risk coefficient CP. The higher the historical plugging and unplugging frequency information of the bidirectional socket to be tested, the greater the historical plugging and unplugging frequency risk coefficient CP.

[0095] The plugging and unplugging force of the bidirectional socket to be tested is detected each time when it is inserted to obtain multiple plugging and unplugging force information. Based on the plugging and unplugging force information, it is determined whether the plugging and unplugging force of the bidirectional socket to be tested each time when it is inserted is within a reasonable range, and the plugging and unplugging force risk coefficient CB is output.

[0096] In actual use, excessive insertion and removal force will wear the sealing ring, while too little insertion and removal force will cause the sealing ring to be loosely locked.

[0097] Specifically, multiple plugging and unplugging force information are compared with the preset plugging and unplugging force standard range. If the plugging and unplugging force information is within the preset plugging and unplugging force standard range, it is determined that the plugging and unplugging force of the bidirectional socket to be tested is reasonable, and the output plugging and unplugging force risk coefficient CB is 0.

[0098] If the plugging and unplugging force information is not within the preset plugging and unplugging force standard range, it is determined that the plugging and unplugging force of the bidirectional socket plug to be tested is unreasonable. The minimum difference between the plugging and unplugging force information and the preset plugging and unplugging force standard range is calculated to obtain the plugging and unplugging force difference, and the plugging and unplugging force risk coefficient CB is obtained based on the plugging and unplugging force difference.

[0099] Based on the historical usage time risk factor CL, historical plug-in frequency risk factor CP and plug-in force risk factor CB, based on the installation and use relationship function Calculate and determine the impact of the installation and use of the two-way socket to be tested on the sealing performance of the two-way socket to be tested to obtain the installation and use risk coefficient W2, where: 、 、 are scaling factors and are all greater than 0.

Step S4 specifically includes the following sub-steps:

[0101] The vibration condition of the environment in which the bidirectional connector to be tested is located is detected in real time to obtain environmental vibration parameter information, where the environmental vibration parameter information includes environmental vibration amplitude information and environmental vibration frequency information.

[0102] The vibration amplitude risk coefficient DC is obtained by determining the effect of the vibration amplitude of the environment in which the two-way socket to be tested is located on the sealing performance of the two-way socket to be tested based on the environmental vibration amplitude information. The greater the environmental vibration amplitude information, the greater the vibration amplitude risk coefficient DC.

[0103] The vibration frequency risk coefficient DP is obtained by determining the effect of the vibration frequency of the environment in which the two-way socket plug to be tested is located on the sealing performance of the two-way socket plug to be tested based on the environmental vibration frequency information. The higher the environmental vibration frequency information, the greater the vibration frequency risk coefficient DP.

[0104] According to the vibration amplitude risk factor DC and vibration frequency risk factor DP, based on the environmental vibration relationship function The environmental vibration risk coefficient DR is calculated, where d1 and d2 are proportional factors and are both greater than 0.

[0105] Step S4 also includes the following sub-steps:

[0106] Based on the durability performance information of the sealing ring, the wear resistance performance of the sealing ring of the two-way socket plug to be tested is obtained, that is, the wear resistance performance information of the sealing ring. Based on the wear resistance performance information of the sealing ring, the influence of the wear resistance performance of the sealing ring of the two-way socket plug to be tested on the sealing performance of the two-way socket plug to be tested is judged to obtain the wear resistance performance coefficient DN of the sealing ring.
