Description

Technical Field

[0001] The present invention belongs to the field of anti-corrosion, and in particular relates to a rubber plate working condition simulation method, device and rubber plate detection platform. Background Art

[0002] Anti-corrosion rubber sheets are products that are laid on the inner walls of industrial transport pipelines or chemical containers. Their function is to prevent chemically corrosive liquids or gases from corroding the inner walls of industrial transport pipelines or chemical containers.

[0003] It can be seen that for anti-corrosion rubber sheets, their resistance to corrosion is their most critical performance indicator. Therefore, before the anti-corrosion rubber sheets leave the factory, their resistance must be tested to ensure that they can achieve the necessary anti-corrosion performance.

[0004] The existing test method is to use a glass container to hold the test medium (i.e., a predetermined corrosive liquid), place the container in a water bath at 80°C or a specified temperature; place the anti-corrosion rubber plate in the glass container, and measure the mass or other performance changes of the anti-corrosion rubber plate.

[0005] However, it is found in actual use that the negative pressure in the pipeline environment usually has a great impact on the resistance performance of the anti-corrosion rubber sheet. Therefore, there is usually an obvious deviation between the test results obtained by the existing test methods and the results of actual use. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides a rubber sheet working condition simulation method, device and rubber sheet detection platform, wherein the rubber sheet detection platform includes a rubber sheet working condition simulation device, and the rubber sheet working condition simulation device, together with the rubber sheet working condition simulation method, can fully simulate the actual use condition of the rubber sheet with a predetermined negative pressure, and the rubber sheet detection platform can accurately detect the tolerance of the rubber sheet.

The pressure controller has a pressure-acting part, an adjusting spring and a control switch. The adjusting spring is connected to the pressure-acting part. The adjusting spring is used to adjust the action pressure value of the pressure-acting part. The pressure-acting part is connected to the control switch. The exhaust valve and the control switch constitute a pressure maintaining circuit. When the pressure applied to the pressure-acting part is greater than or equal to the action pressure value, the control switch is closed, the pressure maintaining circuit is opened, and the exhaust valve exhausts air from the pressure container. When the pressure applied to the pressure-acting part is less than the action pressure value, the control switch is disconnected, the pressure maintaining circuit is broken, and the exhaust valve stops exhausting air from the pressure container.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following embodiments and the accompanying drawings specifically illustrate a rubber plate working condition simulation method, device and rubber plate detection platform of the present invention. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0035] like Figure 1 As shown, a rubber sheet working condition simulation method S100 in this embodiment includes the following steps:

[0036] Step S1: stick the rubber sheet to the inner wall of the sealed container. In this embodiment, the sealed container is cylindrical, and the rubber sheet is laid in a manner of fully sticking to the inner wall of the sealed container.

[0037] Step S2: adding a predetermined corrosive liquid into the sealed container. Specifically, the predetermined corrosive liquid is any one of phosphoric acid, hydrochloric acid, sulfuric acid, and sodium hydroxide. In this embodiment, the predetermined corrosive liquid is selected according to the actual application scenario of the rubber sheet.

[0038] Step S3: evacuate the sealed container until the air pressure in the sealed container reaches the predetermined operating pressure, and heat the sealed container until the temperature in the sealed container reaches the predetermined operating temperature. Specifically, the gauge pressure of the predetermined operating pressure is -0.09MPa, and the range of the predetermined operating temperature is 70°C to 90°C. In this embodiment, the predetermined operating temperature is determined according to the actual application scenario of the rubber sheet, and the sealed container is heated by an external heat source at the lower part of the sealed container.

[0039] Step S4: Maintaining the temperature in the sealed container within a predetermined time, specifically, the predetermined time is 7 days to 56 days.

[0040] In this embodiment, in order to accurately simulate the working condition of the rubber sheet, the process of the rubber sheet working condition simulation method S100 is implemented multiple times to obtain rubber sheets with simulated working conditions at multiple predetermined times. Specifically, the predetermined time may be 7 days, 14 days, 28 days or 56 days, and the mass change rate between multiple nodes of the rubber sheet is obtained with multiple predetermined times as nodes, thereby achieving an accurate simulation of the gradual change of the working condition. Preferably, the mass change rate between multiple nodes of the rubber sheet is obtained with 7 days, 14 days and 28 days as nodes, and the tolerance of the rubber sheet is judged by visually observing whether there are defects such as cracks and bubbles on the surface of the rubber sheet.

[0041] like Figure 2-4 As shown, a rubber sheet working condition simulation device in this embodiment is used to cooperate with the rubber sheet working condition simulation method S100 to achieve the best simulation of the rubber sheet working condition, thereby performing a working condition simulation test on the rubber sheet.

[0042] The rubber sheet working condition simulation device includes a container body 10 , a container cover assembly 20 and a heating box 30 . In the present embodiment, the container body 10 is cylindrical, and the heating box 30 is used to heat the container body 10 .

[0043] The container body 10 has a container inner cavity 10 a, which is used to simulate the working condition of the rubber plate. The container inner cavity 10 a is sealed by the container cover assembly 20 .

[0044] The container cap assembly 10 includes a container cap body 21 , a thermometer 22 , an air extraction valve 23 , a vacuum gauge 24 , and a pressure controller 25 .

[0045] The container cover body 21 is disposed on the container body 10 to cover the container body. In this embodiment, there is a sealing ring between the container cover body 21 and the container body 10, and the container cover body 21 is fixed to the container body 10 by threaded connection.

[0046] The thermometer 22 , the air extraction valve 23 , the vacuum gauge 24 and the pressure controller 25 are all arranged on the container cover body 21 .

[0047] The reading end of the thermometer 22 is located on the outside of the container body 10, and the measuring end of the thermometer 22 is located in the container inner cavity 10a and is not immersed in the predetermined corrosive liquid. The thermometer 22 is used to measure the temperature of the predetermined corrosive liquid in real time. In this embodiment, the thermometer 22 is sealed and penetrated on the container cover body 21 through a sealing ring.

[0048] The air extraction valve 23 is used to extract air from a predetermined sealed container. In this embodiment, the air extraction valve 23 is sealed and mounted on the container cover body 21 via a sealing ring.

[0049] The reading end of the vacuum gauge 24 is located on the outside of the container body 10, and the measuring end of the vacuum gauge 24 is located in the container inner cavity 10a. The vacuum gauge 24 is used to measure the air pressure value of the container inner cavity 10a in real time. In this embodiment, the vacuum gauge 24 is sealed and penetrated on the container cover body 21 through a sealing ring.

[0050] The pressure controller 25 is located inside the inner cavity 10a of the container. The pressure controller 25 has a pressure-actuated member (not shown in the drawings), an adjusting spring (not shown in the drawings) and a control switch (not shown in the drawings).

[0051] The adjusting spring is connected to the pressure-acting part. The adjusting spring is used to adjust the action pressure value of the pressure-acting part. The pressure-acting part is connected to the control switch. The exhaust valve and the control switch constitute a pressure maintaining circuit. In the present embodiment, the pressure-acting part is a medium inlet containing a movable steel ball. The adjusting spring is connected to the movable steel ball, and the movable steel ball is rigidly connected to the control switch knife. The adjusting spring is adjusted so that the action pressure of the movable steel ball is -0.09MPa gauge pressure. That is, when the air pressure in the container cavity 10a is greater than or equal to -0.09MPa gauge pressure, the control switch is pushed to close by the movable steel ball, the pressure maintaining circuit is opened, and the exhaust valve exhausts air from the pressure container. When the pressure on the pressure-acting part is less than the action pressure value, the control switch is disconnected, the pressure maintaining circuit is broken, and the exhaust valve stops exhausting air from the pressure container. In this way, the internal pressure of the container cavity 10a will always be maintained at -0.09MPa gauge pressure.

[0052] The inner surface of the heating box 30 is provided with a plurality of wiring pipes 31, which are used for wiring inside and outside the container body 10, and the outer surface of the wiring pipes is wrapped with a heat-insulating medium. In the present embodiment, the wiring pipes 31 are evenly distributed along the circumference of the heating box, the wiring pipes 31 protrude from the inner surface of the heating box 30 and are perpendicular to the inner surface of the heating box 30, one end of the wiring pipes 31 opens to the outer surface of the heating box 30, and the other end opens to the interior of the heating box 30, and the heat-insulating medium is preferably heat-insulating cotton.

[0053] The process of implementing the rubber sheet working condition simulation method S100 in cooperation with the rubber sheet working condition simulation device in this embodiment is as follows:

[0054] First, the rubber sheet is fully attached to the inner wall of the container body 10, and the predetermined corrosive liquid is poured into the container body 10, and the amount poured is 1 / 4 to 1 / 2 of the maximum height of the container cavity 10a. Then, the container cavity 10a is sealed by the container cover assembly 20. At this time, because the pressure of the container cavity 10a is greater than -0.09MPa gauge pressure, the exhaust valve 23 starts to exhaust the container cavity 10a until the pressure of the container cavity 10a is equal to -0.09MPa gauge pressure. At the same time, the container body 10 is placed in the heating box 30, and the thermometer is The data of the vacuum gauge 22 and the vacuum gauge 23 are led out through the signal line, and are led out of the heating box 30 through the wiring pipe 31, and are connected to the signal of the external data display device. In particular, the signal line exposed in the inner cavity 10a of the container and the mouth of the wiring pipe 31 in the heating box 30 should be insulated with insulation cotton, and then all the remaining openings of the wiring pipe 31 in the heating box 30 should be sealed. After completing the above work, the container body 10 is heated by the heating box 30. Due to the insulation and sealing treatment, the heating box 30 During the heating process, the sheath of the signal line will not be damaged due to overheating. The closed wiring pipe 31 makes the heating box 30 closed relative to the external environment during the heating process. In this way, the heating process can be carried out effectively without affecting the transmission of the signal. During the heating process, the temperature data and pressure data of the container cavity 10a detected by the thermometer 22 and the vacuum gauge 23 are displayed in real time through the data display device for real-time observation by the operator. Then, when the temperature of the predetermined corrosive liquid reaches the predetermined operating temperature, the heating of the container body 10 is stopped, and the temperature of the predetermined corrosive liquid is maintained at the predetermined operating temperature. During the heating process, the pressure of the container cavity 10a will continue to change. Through the pressure controller 25, the pressure of the container cavity 10a will always be maintained at -0.09MPa gauge pressure. Finally, the temperature of the predetermined corrosive liquid is maintained at the predetermined operating temperature. The mass change rate between multiple nodes of the rubber sheet is obtained with the 7th day, the 14th day and the 28th day as nodes, and the tolerance performance of the rubber sheet is judged by identifying whether there are cracks and / or bubbles on the surface of the rubber sheet.

[0055] like Figure 5-6 As shown, a rubber sheet detection platform in this embodiment is used to perform a working condition simulation test on the rubber sheet and to accurately detect the rubber sheet after the working condition simulation test.

[0056] The rubber sheet inspection platform includes a rubber sheet working condition simulation device, an inspection table 40, a lighting component 50, an indication component 70 and a control unit (not shown in the drawings). In this embodiment, the rubber sheet working condition simulation device is the above-mentioned rubber sheet working condition simulation device.

[0057] The inspection table 40 is used to place the same rubber sheet before and after the working condition simulation test. In this embodiment, the inspection table 40 is arranged horizontally, and the container body 10 with the inner wall fully covered with the rubber sheet is placed on the inspection table 40.

[0058] The lighting assembly 50 includes a lighting fixture 51 , a high-intensity lamp 52 and a sunshade 53 . In the present embodiment, the high-intensity lamp 52 and the sunshade 53 are both mounted on the lighting fixture 51 and are located below the lighting fixture 51 .

[0059] The strong light 52 is a ring light for illuminating the rubber sheet. In this embodiment, when inspecting the rubber sheet, the strong light 52 is located directly above the opening of the container body 10, and the distance between the strong light 52 and the opening of the container body 10 is in the range of 150mm-250mm.

[0060] The shading plate 53 is arranged directly above the high-intensity lamp 52 to prevent ambient light from affecting the lighting effect of the high-intensity lamp 52 and to avoid light pollution to the environment. In the present embodiment, the shading plate 53 is concave in shape, and the opening of the shading plate 53 faces the opening of the container body 10, so that the shading plate 53 forms a blockage in the direction of the high-intensity lamp 52 other than the container body 10.

[0061] The indicating component 70 includes a qualified indicator light and a failed indicator light. The indicating component 70 is used to provide light prompts according to the detection results of the rubber sheet after the working condition simulation test.

[0062] The control unit includes a collection unit and a processing unit. The processing unit includes a processor and a memory. The memory is used to store a processing program, and the processor is used to execute the processing program.

[0063] The acquisition unit includes an industrial camera 61, which is used to sample the appearance of the rubber plate to obtain a sampling image. The industrial camera 61 is set on the central axis of the ring light 52 and is located below the ring light 52. In this embodiment, the industrial camera 61 is installed on the lighting fixture 51, and the distance between the industrial camera 61 and the opening of the container body 10 ranges from 100mm to 150mm.

[0064] The processing program includes an identification program and a selection indication program. The identification program is used to compare and identify the sampling images before and after the working condition simulation test.

[0065] Once the identification program identifies that the sampling image after the working condition simulation has cracks and / or bubbles compared to the sampling image before the working condition simulation test, the indication program is selected to control the unqualified indicator light to light up; once the identification program identifies that the sampling image after the working condition simulation has no change compared to the sampling image before the working condition simulation test, the indication program is selected to control the qualified indicator light to light up.

[0066] The working process of the rubber plate detection platform in this embodiment is as follows:

[0067] First, the rubber sheet is fully attached to the inner wall of the container body 10, and the container body 10 is placed directly below the lighting assembly 50. The control unit is started, and the appearance of the rubber sheet is sampled by the industrial camera 61 to obtain an initial sampling image. The initial sampling image is stored in the recognition program in the form of data through the processor. Then, a predetermined corrosive liquid is poured into the container body 10, and a working condition simulation test is performed on the rubber sheet by the rubber sheet working condition simulation device and the rubber sheet working condition simulation method. After the working condition simulation test is completed, the predetermined corrosive liquid in the container body 10 is poured out. Out, and place the container body 10 again directly under the lighting component 50, start the control unit again, through the industrial camera 61, the identification program and the selection indication program, the indication component 70 will give a visual prompt according to the inspection result of the rubber sheet. When the qualified indicator light is on, it means that the rubber sheet has no cracks and / or bubbles on the surface after the simulated working condition test, which means that the tolerance of the rubber sheet is qualified; when the unqualified indicator light is on, it means that the rubber sheet has cracks and / or bubbles on the surface after the simulated working condition test, which means that the tolerance of the rubber sheet is unqualified.

[0068] The above-mentioned implementation modes are preferred cases of the present invention and are not used to limit the protection scope of the present invention.
