Description

Technical Field

[0001] This invention relates to the field of performance testing technology for gas pressure regulating and stabilizing devices, specifically a comprehensive performance testing system for gas pressure regulating and stabilizing devices. Background Technology

[0002] Gas transmission and distribution systems are similar to electricity transmission and distribution systems, both employing high-pressure transmission for low-pressure use. The maximum pressure of long-distance pipelines can typically reach 10 MPa, while the pressure at the end-user terminal is only about 2-3 kPa. The gas transmission and distribution system requires 3-5 stages of pressure reduction before meeting final usage requirements. This pressure reduction process is achieved through pressure regulating and stabilizing devices. These devices reduce pressure by filling a relatively large cavity with a small orifice of the high-pressure medium; essentially, they reduce pressure by throttling.

[0003] However, existing pressure regulating and stabilizing devices require testing by staff after a period of use. However, the equipment for testing these devices is scattered and the testing process is easily affected by human factors. When internal parts of the pressure regulating and stabilizing device age and cause the gas pressure regulator to malfunction, staff cannot detect the problem immediately, leading to longer maintenance time and reduced operational stability of the device.

[0004] Therefore, it is necessary to provide a comprehensive performance testing system for gas pressure regulating and stabilizing devices to solve the above problems. Summary of the Invention

[0011] According to the above technical solution, the temperature gauge, flow meter, and pressure gauge II are installed on the secondary pipeline. The secondary pipeline is also equipped with valve I, filter device I, and valve II.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-10 The present invention provides a technical solution: a comprehensive performance testing system for a gas pressure regulating and stabilizing device, comprising a main pipeline 1, two sets of auxiliary pipelines 2, an outlet pipeline 3, a buffer mechanism 4, and a pressure regulator 5. The main pipeline 1, auxiliary pipelines 2, and outlet pipeline 3 are arranged sequentially from right to left. The two sets of auxiliary pipelines 2 are arranged side by side, and their two ends are respectively connected to the main pipeline 1 and the outlet pipeline 3. The buffer mechanism 4 is also connected to the two sets of auxiliary pipelines 2 through pipelines. The pressure regulator 5 is installed on the main pipeline 1. After the gas enters from the main pipeline 1, it enters one of the auxiliary pipelines 2 and then enters the outlet pipeline 3. The pressure regulator 5 reduces the pressure of the gas before it enters the next stage, thus completing the gas pressure regulating and stabilizing process.

[0035] It should be noted that the pressure regulator 5 adjusts the gas pressure from the higher pressure at the inlet to the required outlet pressure. Its pressure regulation method is existing technology and will not be described in detail here.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, a pressure gauge 11 is installed on the main pipeline 1. The pressure gauge 11 is used to detect the gas pressure when passing through the main pipeline 1.

[0037] Pressure gauge 31 is also installed on outlet pipe 3. Pressure gauge 31 is used to detect the gas pressure when passing through outlet pipe 3.

[0038] Specifically, such as Figure 1 and Figure 2 As shown, the secondary pipeline 2 is equipped with valve 21, filter 22, thermometer 23, flow meter 24, pressure gauge 25, and valve 26. Filter 22, thermometer 23, flow meter 24, and pressure gauge 25 are located between valve 21 and valve 26. Filter 22 is located on the side closer to the main pipeline 1. The order of thermometer 23, flow meter 24, and pressure gauge 25 is not limited. Valve 21 and valve 26 are used to control the gas entering the secondary pipeline 2. Filter 22 is used to filter impurities in the gas entering the secondary pipeline 2. The thermometer 23 is used to detect the temperature of the gas in the secondary pipeline 2. The flow meter 24 is used to detect the flow rate of the gas in the secondary pipeline 2. Pressure gauge 25 is used to detect the pressure of the gas in the secondary pipeline 2.

[0039] Furthermore, such as Figure 1 and Figure 2 As shown, each of the secondary pipes 2 is connected to a branch pipe 27. The branch pipe 27 is located between valve 1 21 and filter device 1 22. Each branch pipe 27 is equipped with a valve 3 28. The other end of the branch pipe 27 is connected to a collection pipe 29, which is connected to the buffer mechanism 4.

[0040] Furthermore, such as Figure 3 As shown, a filter screen 221 is fixedly connected inside the filter device 22. A fan wheel 222 is connected to the bearing inside the filter device 22. The fan wheel 222 is located on the side of the filter screen 221 near the valve 21. Several fan blades are provided on the fan wheel 222. The fan blades are provided with arc surfaces. The filter screen 221 is used to filter impurities in the gas entering the secondary pipe 2. The fan wheel 222 is used to clean impurities on the surface of the filter screen 221 to prevent impurities from accumulating.

[0041] It should be noted that the direction of the fan blade's arc surface can be selected according to actual needs. Figure 3 The arc surface is set in a clockwise direction. The fan wheel 222 is equipped with a one-way bearing, which can only rotate in one direction. It is set when the gas enters the auxiliary pipe 2 from the main pipe 1 and then enters the filter device 22. At this time, the gas flows in the forward direction. Otherwise, it flows in the reverse direction. Therefore, the fan wheel 222 can only rotate under the action of the forward airflow. It will not rotate under the action of the reverse airflow.

[0042] When the fan wheel 222 rotates under the action of the forward gas flow, the filter screen 221 filters impurities from the gas flow that has passed through the filter device 22. When the fan wheel 222 rotates, the fan blades clean the surface of the filter screen 221. Some of the cleaned impurities will adhere to the fan wheel 222, while some will continue to disperse inside the filter device 22. As the fan wheel 222 continues to rotate, under the action of centrifugal force, the cleaned impurities will be thrown to the side away from the filter screen 221. Since the filter screen 221 restricts the flow of impurities, they will continue to disperse inside the filter device 22. When the gas flows in the opposite direction, the reverse airflow can backwash the filter screen 221 and clean it, achieving self-cleaning of the filter screen 221 and reducing the possibility of clogging. Since the gas flows in the opposite direction, the fan wheel 222 does not rotate, and the filter screen 221 does not restrict the position of impurities inside the filter device 22. Therefore, the impurities will disperse in the flowing gas flow and flow with the airflow to the buffer mechanism 4, where they will be collected.

[0043] Specifically, such as Figure 1 and Figure 4 As shown, the buffer mechanism 4 includes a buffer tank 41, a filter device 2 47, an air pump 49, a three-way pipe 1 and a three-way pipe 2. The buffer tank 41 is provided with an outlet 42 and an inlet 43. The buffer tank 41 is connected to the collection pipe 29.

[0044] Furthermore, such as Figure 4 As shown, both T-pipe 1 and T-pipe 2 have three openings. The three openings of T-pipe 1 are connected to pipe 1 44, pipe 2 46 and pipe 3 48 respectively. The other end of pipe 1 44 is connected to outlet 42. Pipe 1 44 is equipped with valve 45. Pipe 2 46 is equipped with valve 5 410. The other end of pipe 2 46 is connected to air, i.e. exposed to air. Filter device 2 47 and air pump 49 are installed on pipe 3 48. Filter device 2 47 is located close to T-pipe 1, and pipe 3 48 is located away from T-pipe 1.

[0045] The other end of pipe 3 48 is connected to one of the openings of tee pipe 2. The other two openings of tee pipe 2 are connected to pipe 4 411 and pipe 5 413 respectively. The other end of pipe 4 411 is connected to inlet 43. A valve 6 412 is installed on pipe 4 411, and a valve 7 414 is installed on pipe 5 413. A collecting device 415 is connected to the other end of pipe 5 413. Valves 4 45, 5 410, 6 412, and 7 414 are used to control the opening of the corresponding pipes. Filtering device 2 47 is used to filter impurities in the gas entering buffer tank 41. Air pump 49 is used to draw gas into buffer tank 41. The collecting device 415 is used to collect the gas in buffer tank 41.

[0046] The structure of filter device 247 is the same as that of filter device 122.

[0047] The comprehensive performance testing system for gas pressure regulating and stabilizing devices also includes an information acquisition module, an analysis and comparison module, and a control module. The information acquisition module is used to collect relevant data such as gas pressure, gas temperature, and gas flow during the operation of the gas pressure regulating and stabilizing device. The analysis and comparison module is used to compare and analyze the gas pressure, gas temperature, and gas flow data obtained by the information acquisition module to determine the abnormal adjustment mode of the gas pressure regulating and stabilizing device, ensuring that the gas can operate stably. The control module is used to perform corresponding control adjustments according to the mode determined by the analysis and comparison module.

[0048] The information acquisition module is electrically connected to pressure gauge 11, temperature gauge 23, flow meter 24, pressure gauge 25, and pressure gauge 31 to achieve information acquisition. The control module is electrically connected to valve 1 21, valve 2 26, valve 3 28, valve 4 45, valve 5 410, valve 6 412, and valve 7 414 to achieve control operation.

[0049] Operating method of the comprehensive performance testing system for gas pressure regulating and stabilizing devices:

[0050] Step 1: Initially, the control module controls the opening of valve 21 and valve 26 on one of the secondary pipelines 2, connecting them to the main pipeline 1 and the outlet pipeline 3 to transmit gas.

[0051] Specifically, for ease of explanation later, valves 1-21, 2-26, 3-28, 4-45, 5-410, 6-412, and 7-414 will be collectively referred to as valves when necessary.

[0052] All valves not mentioned at this time are in the closed state, that is, valve 28 on branch pipe 27 connected to the secondary pipe 2 of this group is closed, and valves 21 and 26 on the other secondary pipe 2 and valve 28 on branch pipe 27 connected to it are also in the closed state.

[0053] Step 2: The information acquisition module collects the gas pressure inside the main pipeline 1, the secondary pipeline 2, and the outlet pipeline 3, as well as the gas temperature and gas flow rate inside the secondary pipeline 2.

[0054] Specifically, the information acquisition module acquires the gas pressure detected by pressure gauge 11, pressure gauge 25, and pressure gauge 31, the actual gas temperature detected by temperature gauge 23, and the gas flow rate obtained by flow meter 24. The actual pressure detected by pressure gauge 11 is recorded as f1, and the pressure detected by pressure gauge 25 is recorded as f... i2 The pressure detected by pressure gauge 31 is recorded as f3. i is the number of the two sets of secondary pipes 2. i is 1 or 2. When i is 1, it is the gas pressure in the secondary pipe 2 that is close to the buffer mechanism 4. When i is 2, it is the gas pressure in the secondary pipe 2 that is far away from the buffer mechanism 4.

[0055] Step 3: The analysis and comparison module performs performance testing and judgment on the gas pressure regulating and stabilizing device based on the information obtained by the information acquisition module, and selects the adjustment method for abnormal situations.

[0056] Specifically, the analysis and comparison module includes the ideal gas pressure range corresponding to the gas pressure detected by pressure gauge 11 and pressure gauge 25, the allowable pressure deviation threshold during gas transmission, the pressure drop threshold, and the gas temperature threshold in the secondary pipeline 2. The gas pressure range is (F1, F1'). When the actual pressure detected by pressure gauge 11 and pressure gauge 25 is within this range, it is considered ideal. F1 is the minimum allowable pressure; below this pressure, it will affect the normal transmission of gas and the normal pressure regulation of the pressure regulator 5. F1' is the maximum allowable pressure; above this pressure, there will be safety hazards due to high pressure during gas transmission. The pressure deviation threshold is denoted as n, used to judge the sealing performance of filter 221 and pipeline 2. When f i2 When f ∈ (f1-n, f1+n), it is an ideal state, indicating that the connection of secondary pipe 2 and the filtration of filter 221 are normal; the pressure drop threshold is denoted as ΔF, when f i2 When -f3≥△F, it is a normal situation, indicating that the pressure regulator 5 can perform normal pressure reduction operation; when the actual temperature in the secondary pipe 2 is higher than the temperature threshold, it is an abnormal state, and the information acquisition module will issue an alarm. The actual temperature in the secondary pipe 2 not being higher than the temperature threshold is the basis for subsequent comparative analysis and judgment.

[0057] It should be noted that the ideal gas pressure range can be adjusted and set according to the actual gas consumption throughout the day, based on different time periods; the actual gas flow rate obtained by the information acquisition module is used in this application to monitor the flow rate status.

[0058] Taking the pressure data obtained from the secondary pipe 2 near the buffer mechanism 4 as an example, since the pressure is reduced by the pressure regulator 5 during the gas transmission process, the pressure at f1 and f2 is lower than that at f3. 12 ∈ (F1, F1'), f 12 ∈ (f1-n, f1+n), f 12 -f3 > △F indicates normal operation, while f1 = f 12 Under normal and ideal conditions, secondary pipeline 2 transmits gas normally without leakage, and the gas pressure regulating and stabilizing device operates normally.

[0059] Abnormal situation 1: The gas pressure detection of main pipeline 1 is abnormal;

[0060] When f1≥F1', the gas pressure inside the main pipeline 1 is high, and the pressure regulating inlet pressure of the pressure regulator 5 is also high, requiring buffering of the high-pressure gas. Figure 5As shown, while maintaining the initial gas transmission, the control module controls the valve 3 28 on the branch pipe 27 connected to the secondary pipe 2 near the buffer mechanism 4 to open, and at the same time controls the valve 45 and valve 6 412 to open, and controls the gas pump 49 to start, so as to introduce the gas in the secondary pipe 2 into the buffer tank 41, buffer and divide the gas entering the secondary pipe 2, and avoid safety hazards caused by the high gas pressure in the main pipe 1.

[0061] When f1≤F1, the gas pressure inside the main pipeline 1 is low. The analysis and comparison module will issue an alarm to prevent the normal transmission of gas and the normal pressure reduction operation of the pressure regulator 5 from being affected by the low pressure inside the main pipeline 1.

[0062] Abnormal situation 2: In f 12 When the reading is ≥f1+n, pressure gauge 25 indicates an abnormality. The analysis and comparison module will issue an alarm. Personnel will then inspect and replace pressure gauge 25. To ensure the accuracy of the test results, the auxiliary gas transmission pipe 2 needs to be replaced. Figure 6 As shown, while maintaining the initial gas transmission, the control module controls the valves 21 and 26 on the secondary pipeline 2 away from the buffer mechanism 4 to gradually open, and at the same time controls the valves 21 and 26 on the secondary pipeline 2 that initially transmits gas to gradually close, so as to replace the secondary pipeline 2 when the gas transmission is completed, and avoid incorrect judgment due to abnormal detection by pressure gauge 25.

[0063] In f 12 When the pressure is ≤f1-n, it may be due to reduced sealing or blockage of filter 221 inside the secondary pipe 2, resulting in a reduction in fuel flow through the secondary pipe 2. Consequently, the pressure detected by pressure gauge 25 drops significantly, and further supplementary tests are needed to determine the specific cause.

[0064] Supplementary testing: such as Figure 7 As shown, first replace the secondary gas transmission pipeline 2. Then, control the valves 1 (21) and 2 (26) on the original secondary gas transmission pipeline 2 to close. Next, control the valve 3 (28) on the connected branch pipeline 27 to open, control the valves 5 (410) and 6 (412) to open, and control the air pump 49 to start, pumping air into the original secondary gas transmission pipeline 2. After the pressure value detected by pressure gauge 2 (25) reaches F1', control the valves 5 (410), 6 (412), and 3 (28) to close, and stop the air pump 49 to allow the pressure in the secondary pipeline 2 to be maintained for a certain period of time. The specific time is set manually. After a certain period of time, the information acquisition module re-acquires the pressure data detected by pressure gauge 2 (25). At this time, the pressure data is recorded as f. 12 ';

[0065] If f 12 If '∈(f1-n, f1+n), then the secondary pipe 2 does not have a problem with reduced sealing performance, and the original f12 ≤f1-n is caused by filter 221 being clogged, requiring filter 221 to be self-cleaned. Figure 8 As shown, the control module controls the valve 28 on the branch pipe 27 connected to the original gas transmission secondary pipe 2 to open, the valve 26 on the original gas transmission secondary pipe 2 to partially open, the control valve 45 to open, and the control valve 414 to open. At the same time, it controls the gas pump 49 to start, using the reverse gas flow in the secondary pipe 2 to self-clean the filter screen 221. Meanwhile, the filter device 47 filters and collects impurities in the gas, and the collection device 415 collects the gas.

[0066] If f 12 If '≤f1-n', it is caused by a decrease in the sealing performance of secondary pipe 2. The analysis and comparison module will issue an alarm, and the staff will inspect and replace secondary pipe 2 and the connection points of the components on secondary pipe 2.

[0067] If f 12 If '≥f1-n' indicates an abnormality detected by pressure gauge 25, the analysis and comparison module will issue an alarm, and staff will inspect or replace pressure gauge 25.

[0068] It should be noted that after the supplementary test is completed, a second supplementary test can be performed on the basis of the supplementary test. At this time, valve 45 is opened again, and after the pressure value detected by pressure gauge 25 reaches F1', valve 5 410 is closed and air pump 49 stops running. As needed, valve 6 412 and valve 45 are closed, and pressure is maintained for a certain period of time to check whether there is leakage inside the buffer mechanism 4, which helps to improve the stability of the buffer mechanism 4 during operation.

[0069] Abnormal situation 3: In f 12 When -f3≤△F, it indicates a fault in voltage regulator 5, which reduces the voltage reduction capacity of voltage regulator 5. The analysis and comparison module will issue an alarm, and staff will then inspect and replace voltage regulator 5.

[0070] Initially, the secondary pipe 2, located away from the buffer mechanism 4, is used for gas transmission. The analysis and comparison module and the control module perform analysis, comparison, and control in the same way as when the secondary pipe 2, located closer to the buffer mechanism 4, is used for gas transmission initially.

[0071] It should be noted that the above-mentioned abnormalities may occur simultaneously. If they occur simultaneously, adjustments should be made in sequence according to the handling methods corresponding to abnormality one, abnormality two, and abnormality three. When staff are inspecting or replacing abnormal parts, the pressure data obtained will not be compared and analyzed in step three. The comparison and analysis will be performed again after the adjustment is completed and the data is stable.

[0072] When the gas pressure regulating and stabilizing device needs to be used for a certain period of time and the gas inside the buffer tank 41 needs to be replaced, such as Figure 9 and Figure 10 As shown, the control module first controls valve 3 28 to close, controls valve 45 and valve 7 414 to open, and controls air pump 49 to start, pumping the gas inside buffer tank 41 into collection device 415 for collection, thus completing the evacuation of buffer tank 41. After collection, it controls valve 45 and valve 7 414 to close, and then controls valve 5 410 and valve 6 412 to open, pumping air into buffer tank 41, thus completing the inflation of buffer tank 41, and thus completing the gas replacement inside buffer tank 41.

[0073] When it is necessary to perform airtightness testing, pressure gauge 25 maintenance, or other component testing on one of the secondary pipes 2, it can be done by replacing the secondary pipe 2 used for gas transmission. When it is necessary to maintain the buffer mechanism 4, it can be done by controlling the valve 28 on the branch pipes 27 connected to the two secondary pipes 2 to close through the control module. Therefore, the testing of the two secondary pipes 2 and the secondary pipes 2 and buffer mechanism 4 are independent of each other. During maintenance, part of the structure can be closed to reduce the impact on other components.

[0074] Step 4: The supplementary detection and control module makes corresponding adjustments based on the determined abnormal situation adjustment method.

[0075] The above methods enable performance testing during the normal operation of gas pressure regulating and stabilizing devices, simplifying the testing process. At the same time, they proactively identify the causes of abnormalities in the gas pressure regulating and stabilizing devices, simplifying subsequent maintenance procedures and thereby improving the operational stability of the gas pressure regulating and stabilizing devices.
