Description

Technical Field

[0001] This invention relates to the field of pipeline valve pressure testing technology, specifically to a fully automatic pipeline valve pressure testing device and its usage method. Background Technology

[0002] In modern construction projects, construction cycles are getting shorter and shorter, and quality requirements are getting higher and higher. For example, in flanged piping systems, valve installation precision is very high, especially for valves used in pressure pipelines that are subject to quality supervision. Therefore, pressure testing of pipeline valves is required to ensure quality. However, the number of construction workers is decreasing and their skill level is decreasing, making it increasingly difficult to fulfill contracts smoothly.

[0003] The traditional, relatively advanced pressure testing method involves welding various tees of different diameters onto a section of large-diameter pipeline. Each time a pipeline valve is pressure tested, it is fixed to the tee using flanges or threaded connections. The pressure test is then conducted using a hand-cranked pressure testing pump connected to that section of pipeline. However, this method only tests the strength and sealing of one side of the valve. The process is cumbersome, labor-intensive, time-consuming, inefficient, and lacks complete functionality.

[0004] To compensate for the adverse effects of insufficient worker quantity and quality, automated equipment is needed to improve work efficiency and quality; at the same time, to meet the needs of different scenarios, the equipment needs to be able to be easily moved between different locations.

[0005] To this end, the project team conducted market research and, in light of actual needs, proposed the fully automatic pipeline valve pressure testing device described in this application. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a fully automatic pipeline valve pressure testing device and its usage method, aiming to solve the problems of inconvenient relocation and low testing efficiency of existing pressure testing equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A fully automatic pipeline valve pressure testing device includes a main frame with load-bearing casters at the bottom, a crane rail fixed to the top of the main frame, a crane beam mounted on the crane rail, and a small cantilever crane mounted on the crane beam. The device also includes:

[0009] The small cantilever crane is assembled with the main body of the device, forming an integral part with the pressure testing device. Whether to assemble the small cantilever crane can be determined according to actual needs. The small cantilever crane is mainly used to lift relatively heavy valves, thereby saving manpower. The heavy-duty casters enable the device to move on the work site to the valve storage location, reducing valve handling work and allowing pressure testing to be carried out directly on site.

[0010] The control cabinet, which integrates the label printer and the flip-up touchscreen, is located inside the main frame of the device and is equipped with a remote control.

[0011] A flip-up touchscreen is installed on the upper part of the control cabinet door, which is embedded in the main frame of the device. This allows operators to rotate the touchscreen 90° to a horizontal position and perform control operations while standing. A label printer is installed in the middle of the control cabinet door to print pass / fail labels after the pipeline valves have been tested, displaying the test results.

[0012] The device platform is fixed inside the main frame of the device and located on top of the control cabinet;

[0013] The pressure testing devices in Group A and Group B have the same structure, are located on top of the device platform, and are connected to the same piping system.

[0014] Valve positioning and adjusting device one and valve positioning and adjusting device two are installed on the device platform to assist valve positioning;

[0015] The adjustment module is located inside the pressure testing device.

[0016] Preferably, both the Group A pressure testing device and the Group B pressure testing device include:

[0017] The fixed backrest is fixed to the top of the device platform;

[0018] A mounting bracket is fixed to the top of the device platform and to the side of the back of the platform.

[0019] A movable base, which is movably mounted on the top of the device platform;

[0020] The jack is fixed inside the fixed frame, with its output end abutting against the movable base;

[0021] A fixed base, which is fixed inside the fixed frame and aligned with the movable base;

[0022] A water storage pipe is installed inside a fixed base and connected to a pressure gauge.

[0023] Water storage pipe 2, which is installed inside the movable base and connected to pressure gauge 2;

[0024] Two rubber pads are positioned on opposite sides of the movable base and the fixed base;

[0025] Water injection holes are located inside the movable base and the fixed base;

[0026] The adjustment module is located between the movable base and the fixed base, and is situated in a module slide groove opened on the top of the device platform.

[0027] The pressure test is conveniently conducted by clamping the movable base with rubber pads and the fixed base with the adjustment module and injecting water into the valve cavity. At the same time, within the stroke range of the movable base, multiple sets of adjustment modules and multiple valve positioning adjustment devices can be used to test multiple valves with the same working pressure at the same time, which greatly improves work efficiency.

[0028] Preferably, both the movable base and the adjustment module are equipped with rollers at their bottom for sliding on the top of the device platform.

[0029] Preferably, the piping system provided between the pressure testing devices A and B includes:

[0030] The water tank is fixed inside the main frame of the device and has a drain pipe with a drain valve on its side.

[0031] Hose 1 and hose 2 are respectively connected to water storage pipe 2 and regulating module;

[0032] The steel pipe has one end connected to the water tank and is connected in sequence to the electric valve in front of the pump, the booster pump, the check valve and the pressure sensor. The other end is connected to two sets of pipelines that are respectively connected to the pressure testing device A and the pressure testing device B.

[0033] The suspension rod is fixed to the bottom of the device platform, and a water receiving tray is fixed to its bottom;

[0034] The drain pipe is fixed to the bottom of the water receiving tray and connected to the water tank;

[0035] The pipe assembly with steel pipe connections includes:

[0036] Pipeline 1, equipped with electric valve 1 and pressure sensor 2, has one end connected to pipeline 1 and the other end connected to water storage pipe 1.

[0037] Pipeline 2, equipped with electric valve 5, has one end connected to pipe 1 and the other end connected to hose 2.

[0038] Pipeline 3 is equipped with electric valve 3 and pressure sensor 3. One end of it is connected to pipeline 1 and the other end is connected to hose 1. Pipeline 3 is also connected to pipeline 4, which is equipped with electric valve 2 and electric valve 4 and is connected to pipeline 1.

[0039] Pipe 4 is connected to a drain pipe aligned with the water receiving tray in the middle. Pipe 5, which is equipped with electric valve 6, is connected to the middle of pipe 4 near electric valve 2. Pipe 5 is connected to pipe 2.

[0040] Pipe 4 connects to the top of electric valve 1, while pipes 3 and 2 connect to the bottom of electric valve 1.

[0041] Preferably, the adjustment module is located between the movable base and the fixed base, and both sides are equipped with rubber pads with scales. It has a water injection pipe inside, a limit foot fixed at the bottom, and the second flexible hose is connected to the water injection pipe through a water injection gate valve.

[0042] Preferably, the valve positioning adjustment device one and the valve positioning adjustment device two include:

[0043] Motor 3 has its output shaft mounted on a gear and fixed inside the scale;

[0044] A toothed rod component that passes through the scale and the device platform and meshes with a gear;

[0045] Motor 2, which is fixed to the top of the scale;

[0046] The lower rubber wheel is rotatably mounted on the side of the toothed rod component and located at the bottom of the device platform. It is connected to the output shaft of motor two via a belt drive structure.

[0047] The upper rubber wheel is rotatably mounted on the side of the toothed rod member and located on the top of the device platform;

[0048] A clamping plate is fixed to the top of the toothed rod component;

[0050] Motor 1 is fixedly connected to the clamping plate, and its output shaft is fixedly connected to the gear-shaped structure at the right support end;

[0051] A locking device is located at the connection between the device platform and the toothed rod component;

[0052] An adjustment device slide groove is provided inside the device platform, and a locking device is located inside the adjustment device slide groove.

[0053] The locking device limits the required number of valve positioning adjustment devices in the adjustment device groove, ensuring that the axis of the supported valve is aligned with the axis of the water injection hole on the base. The opening and closing of the right and left supports are controlled by motor one to adapt to the length of the valve to be tested, so that it is just supported on the valve flange or the bottom of the valve body that are symmetrical on both sides. The toothed rod component is raised and lowered by motor three in the lifting device, so that the axis of the valve on the support coincides with the axis of the water injection hole on the base. Then, the valve positioning adjustment device one and valve positioning adjustment device two are moved with the valve to the fixed base side by motor two, waiting for clamping and pressure testing.

[0054] This system can perform strength tests on both sides of one or more valves, as well as leak tests, offering comprehensive testing capabilities. This improves the reliability of valve testing and reduces construction quality defects and rework caused by defects.

[0055] The small cantilever crane and valve positioning and adjustment devices one and two are controlled by a remote control. The single-valve and multi-valve testing processes are integrated into a one-button operation via programming, achieving fully automated operation. After the valve to be tested is positioned and clamped, parameters such as the valve model, specifications, and working pressure are entered on the touchscreen. The testing process begins after clicking the one-button test button on the touchscreen or remote control.

[0056] A method for using a fully automatic pipeline valve pressure testing device, capable of performing single-valve and multi-valve tests, wherein the single-valve test includes the following steps:

[0057] The pump starts with an electric valve that opens. Electric valve one opens, then the booster pump starts. After the pressure reaches 1.5 times the working pressure (or the set value), pressure sensor two sends pressure data. The booster pump stops, then electric valve one closes (observe the valve body and packing for leaks within 5 minutes). After 5 minutes, pressure sensor two sends pressure data; compare it with the set data. If the difference is not zero, a test failure warning is issued. If the difference is 0, proceed to the next step (the control center records the test data for one side). Electric valve two opens, draining some water from storage pipe one through the test drain pipe. The pressure value transmitted by pressure sensor two is zero. Electric valve two closes, then electric valve three opens, starting the booster pump. After the pressure reaches 1.5 times the working pressure (or the set value), pressure sensor three sends pressure data. The booster pump stops, then electric valves one and three close simultaneously (observe the valve body and packing for leaks within 5 minutes). After 5 minutes, pressure sensors two and three send pressure data; compare it with the set data. If the difference is zero, a test failure warning is issued. If the difference is not zero, a test failure warning is issued; if the difference is 0, proceed to the next step (the control center records the test record, and the valve strength test is now passed) → After a 1-minute interval, electric valve three opens → electric valve one opens → the pressurized water pump starts → after the pressure is increased to 1.1 times the working pressure (or the set value), pressure sensor one sends pressure data → the pressurized water pump stops → electric valve one closes (observe the valve body and packing for any leakage within the specified time) → after the specified time, pressure sensor two sends pressure data, which is compared with the set data. If the difference is not zero, a test failure warning is issued; if the difference is 0, proceed to the next step (the control center records the test record, and the valve tightness test is now passed) → electric valves two and four open, draining some water from storage pipes one and two through the test drain pipe → the pressure value transmitted by pressure sensor two and pressure sensor three is zero → electric valves two, four, and the electric valve before the pump close simultaneously → the label printer prints the valve test label.

[0058] The multi-valve testing procedure includes (taking the testing of 2 valves as an example):

[0059] Before clicking the one-click test button on the touchscreen or remote control, connect hose two to the water injection gate valve of the regulating module and open the water injection gate valve, then begin the test procedure: The electric valve before the pump opens → Electric valve one and electric valve three open → The pressurized water pump starts → After the pressure is increased to 1.5 times the working pressure (or the set value), pressure sensor two sends pressure data → The pressurized water pump stops → Electric valve one and electric valve three open and close (observe the valve body and packing for leakage within 5 minutes) → After 5 minutes, pressure sensor two and pressure sensor three send pressure data; compare it with the set data. If the difference is not significant... If the difference is zero, a test failure warning will be issued; if the difference is 0, proceed to the next step (the control center records the test data for one side) → Electric valves 2 and 4 open, draining some water from storage pipes 1 and 2 through the pressure test drain pipe → Pressure sensors 2 and 3 transmit zero pressure → Electric valves 2 and 4 close → Electric valve 5 opens → The pressurized water pump starts → After the pressure is increased to 1.5 times the working pressure (or the set value), pressure sensor 1 transmits pressure data → The pressurized water pump stops (observe the valve body and packing for leakage within 5 minutes) → After 5 minutes, the pressure sensor transmits zero pressure data. The pressure sensor sends out pressure data, which is compared with the set data. If the difference is not zero, a test failure warning is issued; if the difference is 0, proceed to the next step (the control center records the test data, indicating that the valve strength test is qualified) → After a 1-minute interval, electric valves 1 and 3 open → the pressurized water pump starts → after the pressure is increased to 1.1 times the working pressure (or the set value), pressure sensor 1 sends out pressure data → the pressurized water pump stops (observe the valve body and packing for leakage within the specified time) → after the specified time, pressure sensor 1 sends out pressure data, which is compared with the set data. If the difference is not zero, a test failure warning is issued; if the difference is 0, proceed to the next step (the control center records the test record, and the valve's tightness test is now passed) → Electric valves 2, 4, and 6 are opened, and some water in storage pipes 1, 2, and the regulating module is drained through the pressure test drain pipe → The pressure values ​​transmitted by pressure sensors 1, 2, and 3 approach zero → Electric valves 1, 2, 3, 4, 5, 6, the water injection gate valve, and the electric valve before the pump are closed → The label printer prints the valve test label.

[0119] Please see Figure 1 and 2 The embodiment of the present invention is as follows: A small cantilever crane 4 is installed, and valve positioning adjustment device 1 39, valve positioning adjustment device 2 46, and selection adjustment module 41 are set up according to requirements. Then, water is added to the water tank 23 and the power supply to the control cabinet 5 is connected. The model, specifications, working pressure, and other information of the valve to be tested are input on the flip-screen touch screen 6. The operation of the A-group pressure testing device 37, the B-group pressure testing device 38, and the small cantilever crane 4 is adjusted using the remote control 40. Then, all valves are in the closed reset state. After the adjustment is qualified, the pressure testing of the pipeline valves begins. Strength tests (except for check valves) and valve tightness tests can be performed on both sides of the valve. When the weight of the valve being tested is large, it is transported by crane; when the weight of the valve is small, it is transported manually.

[0120] In this embodiment, please refer to Figure 1 , 2For options 3, 4, 7, 8, 9, 10, and 11, when the valve handle or actuator size does not exceed the valve body length, pressure testing can be performed by directly clamping the valve using the fixed base 7 and the movable base 9. A valve positioning adjustment device 39 is installed between the fixed base 7 and the movable base 9. The valve positioning adjustment device 39 is clamped in the adjustment device groove 44 on the device platform 2 by the locking device 57. The locking device 57 can be a nut thread, for example, the toothed rod member 50 has threads on its surface, the nut is fitted onto the threads, and then it is turned. The two nuts cooperate to clamp the toothed rod member 50 on the device platform 2, thus fixing the toothed rod member 50. Alternatively, other reasonable methods can be used to fix the valve positioning adjustment device 39. Therefore, without further explanation, after powering on, the motor 54 is rotated via remote control 40, causing the left support 55 and right support 56 to swing to the required length of the valve to be tested. The valve is then placed upright on the right-angled left and right supports 56 of the valve positioning adjustment device 39. The valve positioning adjustment device 39 is moved to be flush with the fixed base 7 via motor 52. The toothed rod 50 is raised and lowered via motor 49 in the lifting device. By observing the scale 48 on the rubber pad 17, the axis of the valve to be tested is aligned with the axis of the water injection hole 16 on the fixed base 7. Then, the movable base 9 is pushed towards the other side of the valve to be tested. After the valve is clamped on both sides, the valve input is entered on the flip-type touch screen 6. The working pressure is then set, and the electric valves 24 and 28 are opened before the pump. The pressurized water pump 25 is started to inject water into the water storage pipe 12. The water enters the valve cavity of the valve to be tested through the water injection hole 16 on the fixed base 7. When the pressure reaches 1.5 times the working pressure of the valve (or the set value), the pressure sensor 23 sends a stop signal to the pressurized water pump 25 after the pressure value reaches the set value. The pressurized water pump 25 stops running, and the electric valve 28 closes at the same time. Within 5 minutes, observe whether there is any leakage in the valve body and packing, and whether there is any pressure drop in the pressure gauge 14 and the pressure sensor 23. If there is no leakage, it indicates that the strength of the right side of the valve body is qualified. Then, the electric valve 29 is opened, and the water in the water storage pipe 12 is drained through the test drain pipe 31. Some water is drained until the pressure value of pressure sensor 233 is zero, at which point electric valve 29 is closed. Simultaneously, electric valve 30 is opened, and pressurized water pump 25 is started to inject water into water storage pipe 213. Water enters the valve cavity of the valve to be tested through water injection hole 16 on movable base 9. When the pressure reaches 1.5 times the valve's working pressure (or the set value), pressure sensor 34 sends a stop signal to pressurized water pump 25 after the pressure value reaches the set value. Pressurized water pump 25 stops running, and electric valve 30 closes at the same time. Within 5 minutes, observe whether there is any leakage in the valve body and packing, and whether there is any pressure drop in pressure gauge 215 and pressure sensor 34. If there is no such situation, it indicates that the strength of the left side of the valve body is qualified, and the valve strength test is qualified.After a one-minute interval, open electric valve 28 and electric valve 30, and simultaneously start the booster pump 25. When the pressure reaches 1.1 times the valve's working pressure (or the set value), pressure sensor 32 sends a stop signal to booster pump 25 after reaching the set value, causing booster pump 25 to stop operating. Simultaneously, electric valves 28 and 30 close. According to specifications, observe the valve seals for a minimum test duration of 15-120 minutes, ensuring no visible leakage. Pressure gauge 14, pressure gauge 15, pressure sensor 33, and pressure sensor... If the pressure value of valve 34 does not drop, it indicates that the valve's tightness is qualified. Then, electric valves 29 and 31 are opened, and the water in the pipeline is discharged to the water collection tray 21 through the test drain pipe 35. The water collection tray 21 collects the water spilled during the pressure test and the test drain water and discharges it into the water tank 23. After the strength test and tightness test are completed, the label printer prints the label of the tested valve at 64. Press the one-key reset button, and all valves are reset to the closed state. The moving base is reset to the initial position. The valves that have completed the test are removed, and the test labels are hung or pasted.

[0121] In another embodiment, please refer to Figure 1 , 2For steps 5, 6, 7, 8, 9, 12, and 13, when the valve handle or actuator exceeds the length of the valve body, an appropriate adjustment module 41 needs to be installed between the fixed base 7 and the movable base 9 to prevent the fixed base 7 and the movable base 9 from squeezing the valve handle or actuator during pressure testing. The valve is pressure tested by relaying the adjustment module 41 to clamp it. A valve positioning adjustment device 39 is installed between the two adjustment modules 41. The locking device 57 clamps the valve positioning adjustment device 39 into the adjustment device slide groove 44 on the device platform 2. After power is connected, the motor 54 is rotated by the remote control 40, causing the left support 55 and the right support 56 to swing, reaching the valve to be pressure tested. To adjust the valve's length, place it upright on the right-angled left and right supports 55 and 56 of the valve positioning adjustment device 39. Motor 2 52 moves the valve positioning adjustment device 39 to a position close to the fixed base 7. Motor 3 49 in the lifting device raises and lowers the toothed rod 50. Observe the scale 48 on the rubber pad 17 to align the axis of the valve to be tested with the axis of the water injection pipe 42 of the adjustment module 41 and the water injection hole 16 on the fixed base 7. Then, control the moving base 9 to push the adjustment module 41 towards the other side of the valve to be tested. After the valve is clamped on both sides, input the valve's working pressure on the flip-type touchscreen 6, then open the electric valve 24 and electric valve 28 before starting the pressurized water pump. Water is injected into the water storage pipe 12. The water enters the valve cavity of the valve to be pressure tested through the water injection hole 16 on the fixed base 7 and the water injection pipe 42 of the regulating module 41. When the pressure reaches 1.5 times the working pressure of the valve (or the set value), the pressure sensor 23 sends a stop signal to the pressurized water pump 25 after the pressure value reaches the set value. The pressurized water pump 25 stops running, and the electric valve 28 closes at the same time. Within 5 minutes, observe whether there is any leakage in the valve body and packing, and whether there is any pressure drop in the pressure gauge 14 and the pressure sensor 23. If there is no such situation, it indicates that the strength of the right side of the valve body is qualified. Then, the electric valve 29 is opened, and some water in the water storage pipe 12 is drained through the test drain pipe 31 until the pressure sensor 23... When the pressure value is zero, close electric valve 29; at the same time, open electric valve 30, start pressurized water pump 25 to inject water into water storage pipe 213. Water enters the valve cavity of the valve to be tested through water injection hole 16 on movable base 9 and water injection pipe 42 of regulating module 41. When the pressure reaches 1.5 times the working pressure of the valve (or the set value), the pressure sensor 34 sends a stop signal to pressurized water pump 25 after the pressure value reaches the set value. Pressurized water pump 25 stops running, and electric valve 30 closes at the same time. Observe the valve body and packing for leakage within 5 minutes, and check whether there is pressure drop on pressure gauge 215 and pressure sensor 34. If there is no leakage, it indicates that the strength of the left side of the valve body is qualified, and the valve strength test is qualified.After a one-minute interval, open electric valve 28 and electric valve 30, and simultaneously start the booster pump 25. When the pressure reaches 1.1 times the valve's working pressure (or the set value), pressure sensor 32 sends a stop signal to booster pump 25 after reaching the set value, causing booster pump 25 to stop operating. Simultaneously, electric valves 28 and 30 close. According to specifications, observe the valve seals for a minimum test duration of 15-120 minutes, ensuring no visible leakage. Pressure gauge 14, pressure gauge 15, pressure sensor 33, and pressure sensor... If the pressure value of valve 34 does not drop, it indicates that the valve's tightness is qualified. Then, electric valves 29 and 31 are opened, and the water in the pipeline is discharged to the water collection tray 21 through the test drain pipe 35. The water collection tray 21 collects the water spilled during the pressure test and the test drain water and discharges it into the water tank 23. After the strength test and tightness test are completed, the label printer prints the label of the tested valve at 64. Press the one-key reset button, and all valves are reset to the closed state. The moving base is reset to the initial position. The valves that have completed the test are removed, and the test labels are hung or pasted.

[0122] In another embodiment, please refer to Figure 1 , 2For valves 3, 4, 7, 8, 9, 10, and 11, to improve valve pressure testing efficiency, each pressure testing device needs to simultaneously test two valves with the same working pressure. An adjustment module 41 is installed between the two valves. A valve positioning adjustment device 1 39 and a valve positioning adjustment device 2 46 are respectively installed between the fixed base 7, the adjustment module 41, and the movable base 9. The valve positioning adjustment device 1 39 and the valve positioning adjustment device 2 46 are clamped in the adjustment device slide groove 44 on the device platform 2 by locking devices 57. After power is connected, the motor 1 54 is controlled to rotate by the remote controller 40, causing the left support 55 and the right support 56 to swing to the length of the valve to be tested, thus positioning the valve... The valve is positioned upright on the left and right supports 55 and 56, which are perpendicular to the valve positioning adjustment device 1 39 and valve positioning adjustment device 2 46. Motor 2 52 moves the valve positioning adjustment device 1 39 and valve positioning adjustment device 2 46 to a position close to the fixed base 7 and adjustment module 41. Motor 3 49 in the lifting device moves the toothed rod 50 up and down. By observing the scale 48 on the rubber pad 17, the axis of the valve to be tested is aligned with the axis of the water injection pipe 42 of the adjustment module 41 and the water injection hole 16 on the fixed base 7. Then, the moving base 9 is controlled to push the valve positioning adjustment device 1 39, adjustment module 41, and valve positioning adjustment device 2 46 towards the valve to be tested. On the other side, after the two valves are clamped together, the valve working pressure is input on the flip-type touch screen 6. Then, the electric valves 24, 28, and 3 in front of the pump are opened, and the pressurized water pump 25 is started to inject water and pressurize the water storage pipes 12 and 13. The water enters the valve chambers of the two valves to be tested through the water injection holes 16 on the fixed base 7 and the movable base 9. When the pressure reaches 1.5 times the valve working pressure (or the set value), the pressure sensors 33 and 34 send a stop signal to the pressurized water pump 25 after the pressure value reaches the set value. The pressurized water pump 25 stops running, and at the same time, the electric valves 28 and 30 close. Observe the valve body and filler within 5 minutes. Check for leaks in the material and for pressure drops in pressure gauges 14, 15, 33, and 34. If none of these conditions are found, it indicates that one side of the two valve bodies is of acceptable strength. Then, open electric valves 29 and 31 to drain some water from storage pipes 12 and 13 through the test drain pipe 31 until the pressure value of pressure sensor 33 is zero. Then, close electric valves 29 and 31. Simultaneously, open electric valve 60 and water injection gate valve 62 to start the pressurized water pump 25 to inject water into the water injection pipe 42 of the regulating module 41 and pressurize it. The water enters the valve chambers of the two valves to be tested through the water injection pipe 42. When the pressure reaches 1 / 3 of the valve's working pressure...When it reaches 5 times (or the set value), after the pressure value of pressure sensor 1-32 reaches the set value, it sends a stop signal to the pressure pump 25, and the pressure pump 25 stops running. At the same time, the third electric valve 30 closes. Observe whether there is leakage in the valve body and packing, and whether there is pressure drop in the pressure sensor 1-32 within 5 minutes. If there is no such situation, it indicates that the strength of the other side of the valve body is qualified, and the valve strength test is qualified. After an interval of 1 minute, open the first electric valve 28, the third electric valve 30 and the fifth electric valve 60, and start the pressure pump 25 at the same time. When the pressure reaches 1.1 times (or the set value) of the working pressure of the valve, after the pressure value of the pressure sensor 1-32 reaches the set value, it sends a stop signal to the pressure pump 25, and the pressure pump 25 stops running. At the same time, the first electric valve 28, the third electric valve 30 and the fifth electric valve 60 close. Observe that there is no visible leakage in the valve seal according to the requirements of the specification, and the pressure values of the first pressure gauge 14, the second pressure gauge 15, the pressure sensor 1-32, the pressure sensor 2-33 and the pressure sensor 3-34 do not drop within the shortest test duration of 15 to 120 minutes. If there is no such situation, it indicates that the tightness of the valve is qualified. Then open the second electric valve 29, the fourth electric valve 31 and the sixth electric valve 65, close the injection gate valve 62, and drain the water in the pipeline to the water receiving tray 21 through the pressure test drain pipe 35. The water receiving tray 21 collects the water spilled during the pressure test and the pressure test drain water and discharges them into the water tank 23. After the strength test and tightness test are completed, the label printer 64 prints the label of the tested valve, press the one-key reset button, all valves are reset to the closed state, the mobile base is reset to the initial position, take away the tested valve, and hang or paste the test label.

[0123] Through the strength test and tightness test on both sides of the valve (except for check valves), it provides reliable guarantee for the construction quality of the project; by using two groups of pressure test devices to test 4 valves at the same time, it improves the work efficiency of valve pressure test and saves time; through the mobile and automatically controlled valve pressure test device, it greatly improves the work efficiency and enhances the quality guarantee.
