Description

Technical Field

[0001] This utility model relates to the technical field of oil storage tank testing equipment, specifically an oil storage tank sealing testing device. Background Technology

[0002] In the field of oil storage, the airtightness of oil storage tanks is of paramount importance. Existing oil storage tanks must undergo rigorous airtightness testing before being put into use, in order to eliminate the risk of oil leaks caused by poor tank sealing during use.

[0003] Currently, all existing oil storage tanks must undergo a sealing test before being put into use. The traditional testing method typically involves installing a pressure gauge on the tank, filling it with gas, and then manually observing the gauge reading to determine the tank's sealing performance. However, this method has several drawbacks. First, it cannot automatically record changes in the internal gas pressure, relying entirely on real-time manual observation. This makes it highly susceptible to errors due to human negligence, visual fatigue, and other factors, compromising the accuracy and reliability of the test. Second, manual observation cannot detect subtle pressure changes in a timely manner, potentially failing to identify some underlying sealing problems and posing significant safety hazards for subsequent oil storage. Utility Model Content

[0004] The purpose of this invention is to provide a device for testing the sealing performance of oil storage tanks, so as to solve the defects of existing testing methods, such as the inability to automatically record pressure changes, large testing errors, and difficulty in detecting potential sealing problems, and to achieve accurate and efficient testing of the sealing performance of oil storage tanks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tank sealing performance testing device, comprising a tank body, a testing tube disposed on the tank body, and a testing mechanism for testing the sealing performance of the tank body;

[0006] The detection mechanism includes an installation tube mounted on the detection tube, a display screen fixedly mounted on the installation tube, a pressure sensor fixedly inserted into the installation tube and extending into the tank, and an inflation tube fixedly mounted on the installation tube for filling the tank with gas. The pressure sensor is connected to the display screen via a signal line. During installation, the installation tube is fixedly mounted on the detection tube, the pressure sensor is inserted into the detection tube and extends into the tank, and then the inflation tube is connected to an external gas supply device. Gas is then filled into the tank through the gas supply device and the inflation tube until the gas reaches the rated value. The pressure sensor senses the gas pressure changes in the tank in real time and converts the pressure signal into an electrical signal, which is transmitted to the display screen via the signal line. The display screen processes the received signal and presents it in a visually intuitive data format.

[0007] Preferably, to facilitate control of the connection of the detection tube, a first valve is fixedly installed on the detection tube. This allows for flexible control of the connection and disconnection of the detection tube, facilitating the cutting off or opening of the detection tube as needed during pre-detection preparation and the detection process, ensuring the orderly conduct of the detection operation, and preventing gas leakage from interfering with the detection results.

[0008] Preferably, to facilitate the installation of the mounting tube onto the testing tube, the mounting tube is threaded onto the testing tube. The installation method is simple and convenient, requiring no complex tools or professional installation skills, allowing for quick connection between the mounting tube and the testing tube. Furthermore, the threaded connection provides excellent sealing, effectively preventing air leakage at the connection point and ensuring the accuracy of the test results.

[0009] Preferably, to facilitate early warning when the gas pressure inside the tank decreases: an alarm is fixedly installed on the display screen, and the alarm is connected to the display screen via a signal line. When the gas pressure inside the tank drops to a preset threshold, an alarm can be issued in a timely manner to remind personnel that there may be a sealing problem in the tank, avoiding the potential risk of oil leakage and greatly improving the safety and reliability of the detection.

[0010] Preferably, to facilitate control of the inflation pipe's connection, a second valve is fixedly installed on the inflation pipe. This allows for precise control of gas flow through the inflation pipe, enabling the inflation pipe to be opened or closed as needed during inflation into the tank, ensuring the controllability of the inflation process and preventing over-inflation or under-inflation from affecting the testing results.

[0011] Preferably, to facilitate the discharge of gas from the tank, an exhaust pipe is fixedly installed on the mounting pipe, and a third valve is fixedly installed on the exhaust pipe. After the test is completed, the gas in the tank can be discharged efficiently and conveniently, facilitating the subsequent disassembly and maintenance of the testing mechanism, and also preparing for the next test, thus improving the overall efficiency of the testing work.

[0012] The beneficial effects of this utility model are:

[0013] This invention achieves real-time and accurate detection of gas pressure inside the tank through the design of the detection mechanism, and can intuitively display the data on the display screen. It overcomes the problems of easy error and inability to record pressure changes when manually observing pressure gauges, which greatly improves the accuracy and convenience of detection.

[0014] This invention, through the design of an alarm, can promptly issue an alarm when the gas pressure inside the tank drops to a preset threshold, reminding staff that there may be a sealing problem in the tank, thus avoiding the potential risk of oil leakage and greatly improving the safety and reliability of the detection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment provides a device for detecting the sealing performance of oil storage tanks, such as... Figure 1-2 As shown, the testing device includes a tank 1, a testing tube 2 installed on the tank 1, and a testing mechanism 3 for testing the sealing performance of the tank 1.

[0021] The detection mechanism 3 includes an installation tube 31 mounted on the detection tube 2, a display screen 32 fixedly mounted on the installation tube 31, a pressure sensor 33 fixedly inserted into the installation tube 31 and extending into the tank 1, and an inflation tube 34 fixedly mounted on the installation tube 31 for filling the tank 1 with gas. The pressure sensor 33 is connected to the display screen 32 via a signal line. This enables real-time and accurate detection of the gas pressure inside the tank 1, and the data can be displayed intuitively on the display screen 32. This overcomes the problems of errors caused by traditional manual observation of pressure gauges and the inability to record pressure changes, greatly improving the accuracy and convenience of the detection. During installation, the mounting tube 31 is fixedly installed on the detection tube 2, and the pressure sensor 33 is inserted into the detection tube 2 and extends into the tank 1. Then, the inflation tube 34 is connected to the external gas supply equipment. Gas is then injected into the tank 1 through the gas supply equipment and the inflation tube 34 until the gas reaches the rated value. The pressure sensor 33 senses the gas pressure change in the tank 1 in real time and converts the pressure signal into an electrical signal, which is transmitted to the display screen 32 through the signal line. The display screen 32 processes the received signal and presents it in an intuitive data form.

[0022] To facilitate control of the connection of detection tube 2, a first valve 21 is fixedly installed on detection tube 2. This valve allows for flexible control of the connection and closure of detection tube 2, enabling the tube to be cut off or opened as needed during pre-test preparation and testing, ensuring the orderly conduct of the test operation and preventing gas leakage from interfering with the test results. By manually rotating the valve, the opening and closing state of the internal passage is changed. When the valve is open, detection tube 2 is connected, and gas can flow within it; when the valve is closed, detection tube 2 is cut off, and gas cannot pass through.

[0023] To facilitate the installation of the mounting tube 31 onto the detection tube 2, the mounting tube 31 is threaded onto the detection tube 2. The installation method is simple and convenient, requiring no complex tools or professional installation skills, allowing for quick connection between the mounting tube 31 and the detection tube 2. The threaded connection provides excellent sealing, effectively preventing air leakage and ensuring the accuracy of the test results. Utilizing the helical structure of the thread, rotating the mounting tube 31 engages the internal thread on the mounting tube 31 with the external thread on the detection tube 2, gradually tightening it to achieve a tight connection.

[0024] Furthermore, a sealing ring is provided inside the installation tube 31 that abuts against the end of the detection tube 2, and the sealing ring can seal the gap between the installation tube 31 and the detection tube 2.

[0025] To facilitate early warning when the internal gas pressure of tank 1 decreases, an alarm 321 is fixedly installed on the display screen 32, and the alarm 321 is connected to the display screen 32 via a signal line. When the internal gas pressure of tank 1 drops to a preset threshold, an alarm can be issued in a timely manner to remind personnel that tank 1 may have a sealing problem, avoiding potential oil leakage risks and greatly improving the safety and reliability of the detection. The display screen 32 monitors the data transmitted by the pressure sensor 33 in real time. When the pressure data is lower than the preset alarm threshold, the display screen 32 sends an electrical signal to the alarm 321 via the signal line, triggering the alarm 321 to sound an alarm.

[0026] To facilitate control of the connection of the inflation pipe 34, a second valve 341 is fixedly installed on the inflation pipe 34. This valve allows for precise control of the gas flow through the inflation pipe 34, enabling the pipe to be opened or closed as needed during inflation into the tank 1. This ensures controllability of the inflation process and prevents over- or under-inflation from affecting the testing results. Similar to the first valve 21, the valve's internal passage is opened and closed by manually rotating it, thus controlling the gas flow within the inflation pipe 34.

[0027] To facilitate the venting of gas from tank 1, an exhaust pipe 4 is fixedly installed on the mounting pipe 31, and a third valve 41 is fixedly installed on the exhaust pipe 4. After testing, this allows for efficient and convenient venting of gas from tank 1, facilitating subsequent disassembly and maintenance of the testing mechanism 3, and preparing for the next test, thus improving the overall efficiency of the testing process. After testing, the third valve 41 is manually opened, and the gas inside tank 1 is vented out of tank 1 through the exhaust pipe 4 under the influence of pressure difference.

[0028] The control method of this utility model is controlled by the display screen 32. The control circuit of the display screen 32 can be implemented by those skilled in the art through simple programming. The power supply ground is also common knowledge in the art. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
