Description

Technical Field

[0001] The invention relates to the technical field of safety valve detection, in particular to an intelligent sealing detection device for safety valve production. Background Art

[0002] A safety valve is a special valve whose opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, it prevents the medium pressure in the pipeline or equipment from exceeding the specified value by discharging the medium outside the system.

[0003] Due to the nature of its work, the safety valve's sealing performance is tested greatly. Most of the existing safety valve leakage detection equipment is assembled manually and then tested, which makes the safety valve prone to leakage at the connection between the safety valve and the detection equipment during detection, and it cannot be completely sealed. At the same time, when the safety valve is tested, the specific position of the safety valve cannot be found. The location of the leakage point needs to be detected by other devices, which is more cumbersome. At the same time, there are some iron filings in the valve after the safety valve is produced, which may enter the valve core during detection and cause certain wear on the valve core, thereby reducing the service life of the valve core. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent sealing detection device for safety valve production to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions: An intelligent sealing detection device for safety valve production includes a mounting base, a clamping device, a pressing device, a detection device and a cleaning device. The mounting base is connected to the clamping device, the mounting base is connected to the pressing device, the pressing device is tightly connected to the detection device, and the mounting base is connected to the cleaning device.

[0006] The mounting base is used as the main mounting foundation to provide mounting position and support for other devices. After the device is assembled, the safety valve is clamped and fixed by the clamping device, and then the iron filings in the safety valve are cleaned by the cleaning device to prevent them from entering the valve body after the experiment and damaging the valve body by friction. After the cleaning is completed, the safety valve is connected by the clamping device. The pressure value on the contact surface between the clamping device and the safety valve is fed back, and the angle of the mounting base is adjusted so that the pressure value is within a safe range to prevent leakage on the contact surface between the clamping device and the safety valve due to uneven force on the connection contact surface, thereby improving the efficiency of safety valve sealing detection. At the beginning of the detection, the detection device is used to detect whether the air pressure in the safety valve meets the standard. If the air pressure in the safety valve does not meet the standard, the detection device starts to detect the inside of the safety valve until the leakage point is detected and the leakage point is marked.

[0007] Furthermore, a first driving cylinder, a driving motor, a driving screw, a first adjusting cylinder, a second adjusting cylinder and a second driving cylinder are provided on the mounting base. The output end of the first driving cylinder is tightly connected to the clamping device, the output end of the second driving cylinder is tightly connected to the clamping device, the first driving cylinder and the second driving cylinder are tightly connected, the driving screw at the output end of the driving motor is tightly connected, the driving screw is threadedly connected to the cleaning device, there are four first adjusting cylinders, and the output ends of the four first adjusting cylinders are tightly connected to the bottom of the clamping device, there are four second adjusting cylinders, and the output ends of the four second adjusting cylinders are tightly connected to the clamping device.

[0008] When it is necessary to clean the inside of the safety valve, the driving motor outputs a torque to drive the driving screw to rotate, and the driving screw rotates to drive the cleaning device to move until the cleaning device moves to the working position, the driving screw stops moving, and then the cleaning device starts to clean the safety valve to clean the iron filings and dust remaining in the safety valve to prevent the high pressure during the detection process from causing the iron filings to enter the valve body and cause damage to the inside of the iron filings. When it is necessary to clamp the safety valve, the first driving cylinder and the second driving cylinder output displacement to drive the clamping device to move until the clamping device and the safety valve are fully connected, and then the output displacement is stopped. Then, according to the pressure of the clamping device and the safety valve connection surface detected by the clamping device, the flatness of the clamping device and the safety valve connection surface is detected. According to the detection result, the first adjusting cylinder and the second adjusting cylinder adjust the clamping device so that the clamping device deflects to drive the safety valve to deflect, so that the pressure of the connection surface between the safety valve and the clamping device tends to be within a controllable range, thereby ensuring the flatness of the connection between the safety valve and the clamping device.

[0009] Furthermore, the mounting base is provided with a first mounting groove, a second mounting groove, a third mounting groove, a fourth mounting groove and a first mounting cavity, the clamping device is placed in the first mounting groove, four first adjusting cylinders are placed in the first mounting groove, and the four first adjusting cylinders are distributed at right angles to the bottom of the clamping device, four second adjusting cylinders are placed in the first mounting groove, and four second adjusting cylinders are distributed on both sides of the clamping device, the pressing device is placed in the second mounting groove, and the pressing device and the second mounting groove are slidably connected, the cleaning device is placed in the third mounting groove, and the cleaning device and the third mounting groove are slidably connected, the driving screw is placed in the third mounting groove, and the driving screw is rotatably connected to the third mounting groove at one end away from the driving motor, the first driving cylinder is placed in the fourth mounting groove, and the first driving cylinder and the fourth mounting groove are tightly connected, the second driving cylinder is placed in the fourth mounting groove, and the second driving cylinder and the fourth mounting groove are tightly connected, the driving motor is placed in the first mounting cavity, and the driving motor and the first mounting cavity are tightly connected.

[0010] The first mounting groove provides an installation position for the clamping device, and the four first adjusting cylinders and the four second adjusting cylinders respectively output displacement to adjust the angle of the clamping device in the first mounting groove. The second mounting groove provides an installation position for the pressing device, and the pressing device can be moved in the second mounting groove. The third mounting groove provides an installation position for the cleaning device, and at the same time provides an installation position for the driving screw, providing connection conditions for the driving screw and the cleaning device. The fourth mounting groove provides an installation position for the first driving cylinder and the second driving cylinder.

[0011] Furthermore, the clamping device includes a support plate, a clamping disc and a sealing pad. The support plate is placed in the second mounting groove. The support plate and the second mounting groove are slidably connected. The output end of the first driving cylinder is tightly connected to the support plate. The second driving cylinder is tightly connected to the clamping disc. The end of the clamping disc away from the second driving cylinder is tightly connected to the sealing pad.

[0012] The support plate is used as the main supporting component to support the clamping disc and the sealing pad. When the safety valve needs to be clamped, the first driving cylinder outputs displacement to drive the support plate to move, and the second driving cylinder drives the sealing pad to move at the same time until the sealing pad and the safety valve are connected and stop moving. According to the pressure detection result at the connection between the safety valve and the sealing pad, the first adjusting cylinder and the second adjusting cylinder adjust the angle of the clamping device so that the pressure value at the connection between the safety valve and the sealing pad is within the allowable range, thereby ensuring the flatness of the connection between the safety valve and the sealing pad, thereby ensuring the airtightness of the safety valve during the detection process.

[0013] Furthermore, a plurality of mounting holes are provided on the clamping disc, detection springs and magnets are provided in the plurality of mounting holes, cavities are provided outside the plurality of mounting holes, electromagnetic coils are provided in the cavities, the detection springs are fastened to the mounting holes, one end of the detection spring away from the mounting holes is fastened to the magnets, an air inlet hole is also provided on the clamping disc, and the detection device and the air inlet hole are located on the same axis.

[0014] By setting a mounting hole, a mounting position is provided for the detection spring and the magnet. By setting an air inlet hole, high-pressure gas can enter the safety valve through the air inlet hole. When the safety valve and the sealing pad are pressed tightly, the connection between the sealing pad and the safety valve is squeezed and deformed, causing the magnet to move. The movement of the magnet causes the magnetic field generated by the magnet to move, causing the magnetic flux in the electromagnetic coil to change, thereby generating an induced current. The clamping force is determined based on the corresponding value of the induced current. When the induced current value generated at different positions exceeds a controllable range, the angle of the clamping device is adjusted by the first adjusting cylinder and the second adjusting cylinder, thereby changing the position of the safety valve, thereby adjusting the flatness of the connection between the safety valve and the sealing pad, and preventing the safety valve from leaking during testing due to an uneven connection between the safety valve and the sealing pad.

[0015] Furthermore, the sealing pad is provided with an air intake hole and a detection hole, which are located on the same axis and are connected to each other. There are several detection holes, which are connected to several mounting holes correspondingly, and the magnet is placed in the detection hole at one end away from the mounting hole.

[0016] The air inlet hole allows high-pressure gas to enter the safety valve through the air inlet hole, and the detection hole provides an installation position for the magnet, so that the end of the magnet away from the installation hole can be installed in the detection hole, so that the sealing pad can exert force on the magnet when it is deformed under force.

[0017] Furthermore, the detection device includes a multi-stage cylinder, a rotating motor, a mounting cylinder, a detection probe plate, and a detection probe. The multi-stage cylinder is placed in the air intake hole. The multi-stage cylinder is tightly connected to the clamping disc, the output end of the multi-stage cylinder is tightly connected to the rotating motor, the output end of the rotating motor is tightly connected to the mounting cylinder, a pressure sensor is provided on the mounting cylinder, the output end of the mounting cylinder is tightly connected to the detection probe plate, there are four detection probe plates, a number of detection probes are provided on the detection probe plate, a number of probe mounting grooves are provided on the detection probe, a detection probe and a reset spring are provided on the probe mounting groove, the reset spring is tightly connected to the probe mounting groove, the end of the reset spring away from the probe mounting groove is tightly connected to the detection probe, and the detection probe is slidably connected to the probe mounting groove.

[0018] The probe installation slot is provided to provide an installation position for the detection probe. The pressure sensor is used to detect the air pressure value in the safety valve. When the air pressure value in the safety valve is smaller than the input air pressure value, the installation cylinder outputs displacement to drive the detection probe plate to move, and the movement of the detection probe plate drives the detection probe to move. After the detection probe moves to the working position, the installation cylinder stops outputting displacement. At the same time, the rotating motor starts to rotate to drive the installation cylinder to rotate, and the rotation of the installation cylinder drives the detection probe plate to rotate. The rotation of the detection probe plate drives the detection probe to rotate, so that the detection probe starts to detect the safety valve. When the detection probe rotates one circle, the multi-stage The cylinder output displacement drives the rotating motor to move, thereby driving the detection probe to a deeper level in the safety valve for detection. When it rotates to the leakage position in the safety valve, the high air pressure in the safety valve causes the gas in the valve to flow to the leakage position, increasing the gas flow rate at the leakage point, thereby exerting a force on the detection probe near the leakage point, causing the detection probe to be sucked to the leakage point and mark the leakage point. After marking, since the detection probe is still rotating, the detection probe is reset by the dual action of rotation and reset spring, so that the detection probe can mark the next leakage point.

[0019] Furthermore, a liquid storage chamber, a partition groove and a liquid outlet channel are provided in the detection probe. The liquid storage chamber is filled with a marking liquid, the liquid storage chamber and the liquid outlet channel are connected, the partition groove is placed on the liquid outlet channel, the liquid outlet channel runs through the partition groove, the liquid outlet channel and the probe mounting groove are connected, the partition groove and the probe mounting groove are connected, the partition groove is provided with a partition plate, the detection probe is provided with an abutting groove, the partition plate and the abutting groove abut each other, and the partition plate is provided with a liquid outlet through hole.

[0020] A liquid storage chamber is provided to provide a storage location for the marking liquid. When the detection probe is sucked to the leakage position, the detection probe moves outward to drive the reset spring to stretch. At the same time, the movement of the detection probe drives the abutment groove to push the partition plate upward until the liquid outlet hole moves to the liquid outlet channel, so that the marking liquid in the liquid storage chamber flows out to the liquid outlet channel, and then flows into the probe mounting groove through the liquid outlet channel, so that the detection probe can mark the leakage position.

[0021] Furthermore, the cleaning device includes a mounting block, an air suction pump, a manipulator, a first telescopic cylinder, a steering motor, a second telescopic cylinder and an adsorption tube. The mounting block is threadedly connected to the driving screw, the mounting block is slidingly connected to the mounting base, the mounting block is firmly connected to the air suction pump, the air suction pump is firmly connected to the manipulator, the manipulator is firmly connected to the first telescopic cylinder, the output end of the first telescopic cylinder is firmly connected to the steering motor, the steering motor is firmly connected to the second telescopic cylinder, the output end of the second telescopic cylinder is firmly connected to the adsorption tube, and the input end of the air suction pump is connected to the adsorption tube pipeline.

[0022] By setting up the mounting block, an installation position is provided for other components. When the safety valve needs to be cleaned, the first telescopic cylinder is driven to move by the manipulator, and the movement of the first telescopic cylinder drives the steering motor to move, and the movement of the steering motor drives the second telescopic cylinder to move, and the movement of the second telescopic cylinder drives the adsorption tube to move until the adsorption tube moves into the safety valve. Then, the adsorption tube is driven to move to the corresponding position in the safety valve by the second telescopic cylinder. The suction pump is turned on so that the adsorption tube can adsorb iron filings and dust in the safety valve. At the same time, the output displacement of the first telescopic cylinder drives the steering motor to move, and then the steering motor drives the second telescopic cylinder to move. The movement of the second telescopic cylinder drives the adsorption tube to move. Through the first telescopic cylinder and the steering motor, the adsorption tube can perform comprehensive adsorption and cleaning of the safety valve.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the pressure on the connection contact surface between the clamping device and the safety valve, the installation base adjusts the angle so that the pressure value is adjusted to a safe range, preventing leakage between the connection contact surface between the clamping device and the safety valve due to uneven force on the connection contact surface, thereby improving the efficiency of safety valve sealing detection.

[0024] 2. Use the detection device to detect the specific location of the leak, and then mark the leak to facilitate subsequent maintenance of the safety valve leak.

[0025] 3. By setting up a cleaning device, the iron filings in the safety valve can be cleaned to prevent the iron filings from entering the valve core of the safety valve during the detection process, aggravating the wear of the safety valve and reducing the service life of the safety valve.

[0030] The mounting base 1 is used as the main mounting base to provide mounting position and support for other devices. After the device is assembled, the safety valve is clamped and fixed by the clamping device 2, and then the iron filings in the safety valve are cleaned by the cleaning device 5 to prevent the iron filings from entering the valve body after the experiment starts and damaging the valve body by friction. After the cleaning is completed, the safety valve is connected by the clamping device 3. The pressure value on the connection contact surface between the clamping device 3 and the safety valve is fed back, and the mounting base 1 adjusts the angle so that the pressure value is within a safe range to prevent leakage between the connection contact surface of the clamping device 3 and the safety valve due to uneven force on the connection contact surface, thereby improving the efficiency of the safety valve sealing detection. The detection starts by detecting whether the air pressure in the safety valve meets the standard through the detection device 4. If the air pressure in the safety valve does not meet the standard, the detection device 4 starts to detect the inside of the safety valve until the leakage point is detected and the leakage point is marked, and then the detection is completed.

[0031] like Figure 1-Figure 5 As shown, a first driving cylinder 11, a driving motor 12, a driving screw 13, a first adjusting cylinder 14, a second adjusting cylinder 15 and a second driving cylinder 16 are provided on the mounting base 1, the output end of the first driving cylinder 11 is fastened to the clamping device 3, the output end of the second driving cylinder 16 is fastened to the clamping device 3, the first driving cylinder 11 and the second driving cylinder 16 are fastened, the driving screw 13 at the output end of the driving motor 12 is fastened, the driving screw 13 is threadedly connected to the cleaning device 5, there are four first adjusting cylinders 14, the output ends of the four first adjusting cylinders 14 are fastened to the bottom of the clamping device 2, there are four second adjusting cylinders 15, the output ends of the four second adjusting cylinders 15 are fastened to the clamping device 2.

[0032] When it is necessary to clean the inside of the safety valve, the driving motor 12 outputs a torque to drive the driving screw 13 to rotate, and the driving screw 13 rotates to drive the cleaning device 5 to move until the cleaning device 5 moves to the working position, and then the driving screw 13 stops moving. Then the cleaning device 5 starts to clean the inside of the safety valve to clean the iron filings and dust remaining in the safety valve to prevent the high pressure during the detection process from causing the iron filings to enter the valve body and cause damage to the inside of the iron filings. When it is necessary to tighten the safety valve, the first driving cylinder 11 and the second driving cylinder 16 output The displacement drives the clamping device 3 to move until the clamping device 3 and the safety valve are fully connected, then the output displacement is stopped, and then the flatness of the connection surface between the clamping device 3 and the safety valve is detected according to the pressure of the connection surface between the clamping device 3 and the safety valve detected by the clamping device 3. According to the detection result, the first regulating cylinder 14 and the second regulating cylinder 15 adjust the clamping device 2, so that the clamping device 2 deflects and drives the safety valve to deflect, so that the pressure of the connection surface between the safety valve and the clamping device 3 tends to be within a controllable range, thereby ensuring the flatness of the connection between the safety valve and the clamping device 3.

The device 5 is placed in the third mounting groove 113, the cleaning device 5 is slidingly connected to the third mounting groove 113, the driving screw 13 is placed in the third mounting groove 113, the driving screw 13 is rotatably connected to the third mounting groove 113 at one end away from the driving motor 12, the first driving cylinder 11 is placed in the fourth mounting groove 114, the first driving cylinder 11 and the fourth mounting groove 114 are tightly connected, the second driving cylinder 16 is placed in the fourth mounting groove 114, the second driving cylinder 16 and the fourth mounting groove 114 are tightly connected, the driving motor 12 is placed in the first mounting cavity 115, and the driving motor 12 and the first mounting cavity 115 are tightly connected.

[0034] An installation position is provided for the clamping device 2 through the first installation groove 111, and the four first adjusting cylinders 14 and the four second adjusting cylinders 15 respectively output displacement to adjust the angle of the clamping device 2 in the first installation groove 111. An installation position is provided for the clamping device 3 through the second installation groove 112, and the clamping device 3 can be moved in the second installation groove 112. An installation position is provided for the cleaning device 5 through the third installation groove 113, and an installation position is provided for the driving screw 13, and connection conditions are provided for the driving screw 13 and the cleaning device 5. An installation position is provided for the first driving cylinder 11 and the second driving cylinder 16 through the fourth installation groove 114.

[0035] like Figure 5-Figure 7 As shown, the clamping device 3 includes a support plate 31, a clamping disc 32 and a sealing pad 33. The support plate 31 is placed in the second mounting groove 112. The support plate 31 and the second mounting groove 112 are slidably connected. The output end of the first driving cylinder 11 is fastened to the support plate 31, the second driving cylinder 16 is fastened to the clamping disc 32, and the end of the clamping disc 32 away from the second driving cylinder 16 is fastened to the sealing pad 33.

[0036] The support plate 31 is used as the main supporting component to support the clamping disc 32 and the sealing pad 33. When the safety valve needs to be clamped, the first driving cylinder 11 outputs displacement to drive the support plate 31 to move, and the second driving cylinder 16 drives the sealing pad 33 to move until the sealing pad 33 and the safety valve are connected and stop moving. According to the pressure detection result at the connection between the safety valve and the sealing pad 33, the first adjusting cylinder 14 and the second adjusting cylinder 15 adjust the angle of the clamping device so that the pressure value at the connection between the safety valve and the sealing pad 33 is within the allowable range, thereby ensuring the flatness of the connection between the safety valve and the sealing pad 33, thereby ensuring the airtightness of the safety valve during the detection process.

[0037] like Figure 5-Figure 7 As shown, a plurality of mounting holes 321 are provided on the clamping disc 32, a plurality of mounting holes 321 are provided with detection springs 3211 and magnets 3212, a plurality of mounting holes 321 are provided with cavities outside the plurality of mounting holes 321, an electromagnetic coil is provided in the cavity, the detection spring 3211 and the mounting holes 321 are fastened together, the end of the detection spring 3211 away from the mounting holes 321 is fastened together with the magnet 3212, an air inlet hole 322 is also provided on the clamping disc 32, and the detection device 4 and the air inlet hole 322 are located on the same axis.

[0038] The mounting hole 321 is provided to provide a mounting position for the detection spring 3211 and the magnet 3212. The air inlet hole 322 is provided to allow high-pressure gas to enter the safety valve through the air inlet hole 322. When the safety valve and the sealing pad 33 are pressed tightly, the connection between the sealing pad 33 and the safety valve is squeezed and deformed, causing the magnet 3212 to move. The movement of the magnet 3212 causes the magnetic field generated by the magnet 3212 to move, causing the magnetic flux in the electromagnetic coil to change, thereby generating an induced current. The clamping force is determined based on the corresponding value of the induced current. When the induced current value generated at different positions exceeds the controllable range, the first regulating cylinder 14 and the second regulating cylinder 15 are used to adjust the angle of the clamping device 2, thereby changing the position of the safety valve, thereby adjusting the flatness of the connection between the safety valve and the sealing pad 33, and preventing the safety valve from leaking during the test due to the uneven connection between the safety valve and the sealing pad 33.

[0039] like Figure 5-Figure 7 As shown, the sealing pad 33 is provided with an air intake hole 331 and a detection hole 332, the air intake hole 331 and the air intake hole 322 are located on the same axis, the air intake hole 331 and the air intake hole 322 are connected, there are several detection holes 332, several detection holes 332 and several mounting holes 321 are correspondingly connected, and the magnet 3212 is placed in the detection hole 332 at one end away from the mounting hole 321.

[0040] The high-pressure gas can enter the safety valve through the air intake hole 331, and the detection hole 332 provides an installation position for the magnet 3212, so that the end of the magnet 3212 away from the installation hole 321 can be installed in the detection hole 332, so that the sealing pad 33 can exert a force on the magnet 3212 when it is deformed under force.

[0041] like Figure 7-Figure 10 As shown, the detection device 4 includes a multi-stage cylinder 41, a rotating motor 42, a mounting cylinder 43, a detection probe plate 44, and a detection probe 45. The multi-stage cylinder 41 is placed in the air intake hole 331. The multi-stage cylinder 41 is tightly connected to the pressing disc 32. The output end of the multi-stage cylinder 41 is tightly connected to the rotating motor 42. The output end of the rotating motor 42 is tightly connected to the mounting cylinder 43. A pressure sensor 49 is provided on the mounting cylinder 43. The output end of the mounting cylinder 43 is tightly connected to the detection probe plate 44. There are four detection probe plates 44. A plurality of detection probes 45 are provided on the detection probe plate 44. A plurality of probe mounting grooves 451 are provided on the detection probe 45. A detection probe 46 and a reset spring 47 are provided on the probe mounting groove 451. The reset spring 47 is tightly connected to the probe mounting groove 451. The end of the reset spring 47 away from the probe mounting groove 451 is tightly connected to the detection probe 46.

[0042] The probe installation groove 451 is provided to provide an installation position for the detection probe 46, and the pressure sensor 49 is used to detect the air pressure value in the safety valve. When the air pressure value in the safety valve is smaller than the input air pressure value, the installation cylinder 43 outputs displacement to drive the detection probe plate 44 to move, and the movement of the detection probe plate 44 drives the detection probe 45 to move, until the detection probe 45 moves to the working position, the installation cylinder 43 stops outputting displacement, and at the same time, the rotating motor 42 starts to rotate to drive the installation cylinder 43 to rotate, the installation cylinder 43 rotates to drive the detection probe plate 44 to rotate, and the detection probe plate 44 rotates to drive the detection probe 45 to rotate, so that the detection probe 45 starts to detect the safety valve. When the detection probe 4 After one rotation, the multi-stage cylinder 41 outputs displacement to drive the rotating motor 42 to move, thereby driving the detection probe 45 to detect deeper into the safety valve. When it rotates to the leakage position in the safety valve, the gas in the valve flows to the leakage position due to the high air pressure in the safety valve, so that the gas flow rate at the leakage point becomes larger, thereby exerting a force on the detection probe 46 near the leakage point, so that the detection probe 46 is sucked to the leakage point position and the leakage point is marked. After marking, since the detection probe 45 is still rotating, the detection probe 46 is reset by the dual action of the rotation and the reset spring 47, so that the detection probe 46 can mark the next leakage point.

[0043] like Figure 7-Figure 10As shown, a liquid storage chamber 452, a partition groove 453 and a liquid outlet channel 454 are also provided in the detection probe 45. The liquid storage chamber 452 is filled with a marking liquid. The liquid storage chamber 452 and the liquid outlet channel 454 are connected. The partition groove 453 is placed on the liquid outlet channel 454. The liquid outlet channel 454 passes through the partition groove 453. The liquid outlet channel 454 and the probe mounting groove 451 are connected. The partition groove 453 and the probe mounting groove 451 are connected. The partition groove 453 is provided with a partition plate 48. The detection probe 46 is provided with an abutting groove 461. The partition plate 48 abuts against the abutting groove 461. The partition plate 48 is provided with a liquid outlet through hole 481.

[0044] The liquid storage chamber 452 is provided to provide a storage location for the marking liquid. When the detection probe 46 is sucked to the leakage position, the detection probe 46 moves outward to drive the reset spring 47 to stretch. At the same time, the movement of the detection probe 46 drives the abutment groove 461 to push the partition plate 48 upward until the liquid outlet hole 481 moves to the liquid outlet channel 454, so that the marking liquid in the liquid storage chamber 452 flows out to the liquid outlet channel 454, and then flows into the probe mounting groove 451 through the liquid outlet channel 454, so that the detection probe 46 can mark the leakage position.

[0045] like Figure 2-Figure 3 As shown, the cleaning device 5 includes a mounting block 51, an air suction pump 52, a manipulator 53, a first telescopic cylinder 54, a steering motor 55, a second telescopic cylinder 56 and an adsorption tube 57. The mounting block 51 is threadedly connected to the driving screw 13, the mounting block 51 is slidingly connected to the mounting base 1, the mounting block 51 is firmly connected to the air suction pump 52, the air suction pump 52 is firmly connected to the manipulator 53, the manipulator 53 is firmly connected to the first telescopic cylinder 54, the output end of the first telescopic cylinder 54 is firmly connected to the steering motor 55, the steering motor 55 is firmly connected to the second telescopic cylinder 56, the output end of the second telescopic cylinder 56 is firmly connected to the adsorption tube 57, and the input end of the air suction pump 52 is connected to the adsorption tube 57 by a pipeline.

[0046] The installation block 51 is provided to provide an installation position for other components. When the safety valve needs to be cleaned, the manipulator 53 drives the first telescopic cylinder 54 to move, and the movement of the first telescopic cylinder 54 drives the steering motor 55 to move, and the movement of the steering motor 55 drives the second telescopic cylinder 56 to move, and the movement of the second telescopic cylinder 56 drives the adsorption tube 57 to move until the adsorption tube 57 moves into the safety valve, and then the second telescopic cylinder 56 drives the adsorption tube 57 to move to the corresponding position in the safety valve, and then the suction pump 52 is turned on so that the adsorption tube 57 can adsorb iron filings and dust in the safety valve. At the same time, the first telescopic cylinder 54 outputs displacement to drive the steering motor 55 to move, and then the steering motor 55 drives the second telescopic cylinder 56 to move, and the movement of the second telescopic cylinder 56 drives the adsorption tube 57 to move, and the adsorption tube 57 can be fully adsorbed and cleaned inside the safety valve through the first telescopic cylinder 54 and the steering motor 55.

[0047] The working principle of the present invention is as follows: initially, the safety valve is clamped and fixed by the clamping device 2, and then the safety valve is cleaned by the cleaning device 5. After the cleaning is completed, the safety valve is compressed, and the sealing plate 33 is driven to move by the first driving cylinder 11 and the second driving cylinder 16 until the sealing plate 33 and the safety valve are connected and then stop moving. The connection between the sealing plate 33 and the safety valve is squeezed and deformed, so that the magnet 3212 moves, thereby changing the magnetic flux in the electromagnetic coil to generate an induced current. The size of the compression force is determined according to the corresponding value of the induced current. When the induced current values ​​generated at different positions exceed the controllable range, the angle of the clamping cylinder 2 is adjusted by the first regulating cylinder 14 and the second regulating cylinder 15 to adjust the flatness of the connection between the safety valve and the sealing plate 33. Then, the high-pressure gas is sent into the safety valve. After it is kept stable, the pressure value in the safety valve is detected by the pressure sensor 49. When the pressure value in the safety valve is smaller than the input pressure value, the cylinder driving device 14 is installed. After the detection probe 45 moves to the working position, the installation cylinder 43 stops outputting displacement, and at the same time outputs displacement and torque through the rotating motor 42 and the installation cylinder 43, so that the detection probe 45 starts to detect the safety valve. After the detection probe 45 rotates one circle, the multi-stage cylinder 41 outputs displacement to drive the rotating motor 42 to move, thereby driving the detection probe 45 to detect deeper into the safety valve. When it rotates to the leakage position in the safety valve, the detection probe 46 is sucked to the leakage point position. When the detection probe 46 is sucked to the leakage position, the reset spring 47 is stretched by the outward movement of the detection probe 46. At the same time, the movement of the detection probe 46 drives the abutment groove 461 to push the partition plate 48 upward until the liquid outlet through hole 481 moves to the liquid outlet channel 454, so that the marking liquid in the liquid storage chamber 452 flows out to the liquid outlet channel 454, and then flows to the probe installation groove 451 through the liquid outlet channel 454, so that the detection probe 46 can mark the leakage position, thereby realizing accurate marking of the leakage position.
