An air bag 613 is fixedly connected to the side away from the mounting tube 601. The air bag 613 can be pressed against the inside of the valve to seal it and can adapt to valves of different sizes. A connecting air pipe 614 is fixedly connected between the air bag 613 and the outside of the mounting tube 601. The connecting air pipe 614 can play a ventilation role. A connecting branch pipe 615 is fixedly connected between the connecting air pipe 614 and the mounting tube 606. A tail pipe 616 is fixedly connected to the side of the mounting tube 601 away from the air bag 613. One end of the return spring 605 is fixedly connected to the inside of the mounting tube 601. The other end of the return spring 605 is fixedly connected to one end of the piston plate 604 close to the connector 612. The sliding plug plate 608 is slidably connected to the inside of the mounting tube 606. The pressing column 611 is slidably connected to the top of the mounting cylinder 606. When the valve is pressure tested, the valve is closed and the hydraulic cylinder 3 is started. After the output end of the hydraulic cylinder 3 is extended, the connecting column 5 is driven to move to one side of the clamping and stabilizing mechanism 8, and the extrusion plate 12 can be driven to move to one side of the clamping and stabilizing mechanism 8, so that the extrusion plate 12 can be pressed against the valve, and the pressure of the valve housing can be tested by the hydraulic cylinder 3. After the pressure test of the valve housing is completed, if the valve is not damaged, the electric valve 11 on the ventilation main pipe 9 is closed, and the electric valve 11 on the ventilation branch pipe 10 is opened, so that the gas in the ventilation main pipe 9 can enter the interior of the ventilation branch pipe 10, and enter the interior of the tail pipe 616 through the ventilation branch pipe 10.The gas then pushes the piston plate 604 to move to the side away from the mounting bracket 2.

[0023] The rotating cleaning mechanism 7 includes a fixed frame 701 and two mounting plates 705. The fixed frame 701 can provide a mounting position, and the mounting plates 705 can provide a mounting position. The bottom of the fixed frame 701 is fixedly connected to the top of the mounting base 1 away from the side of the mounting frame 2. The top of the fixed frame 701 is fixedly connected to a mounting box 702, and the inner side of the mounting box 702 is rotatably connected to an impeller ring 703. The impeller ring 703 can rotate under the drive of the airflow. The inner side of the impeller ring 703 is fixedly connected to a rotating plate 704. The rotation of the impeller ring 703 can drive the rotating plate 704 to rotate and provide a mounting position. The two mounting plates 705 are fixedly connected to a hydraulic rod 706 on one side close to the mounting box 702, and the output end of the hydraulic rod 706 is fixedly connected to A connecting bent rod 707 is connected, and the connecting bent rod 707 can provide a connection function. A sliding block 708 is slidably connected to the side of the mounting plate 705 away from the mounting box 702. The sliding block 708 can provide a mounting position and can enable the sliding block 708 to slide inside the mounting plate 705. An air jet 709 is fixedly connected to the side of the sliding block 708 away from the mounting box 702. A ventilation hose 710 is fixedly connected to the side of the air jet 709 close to the hydraulic rod 706. The ventilation hose 710 can play a connecting role. One end of the ventilation hose 710 away from the air jet 709 is fixedly connected to the inside of the impeller ring 703. The ventilation hose 710 runs through the inside of the rotating plate 704. One end of the ventilation main pipe 9 away from the air pump 4 is fixedly connected to the mounting box 7 02, the top of the ventilation branch pipe 10 is fixedly connected to the top of the tail pipe 616, and the valve is fixed to the middle of the clamping and stabilizing mechanism 8. Then, the air pump 4 is started, and the output end of the air pump 4 generates airflow, which enters the interior of the ventilation main pipe 9. At this time, the electric valve 11 on the ventilation main pipe 9 is opened. At this time, the high-pressure airflow in the ventilation main pipe 9 enters the interior of the installation box 702, so that the impeller ring 703 can be driven to rotate by the high-pressure airflow. After the impeller ring 703 rotates, the rotating plate 704 can be driven to rotate. After the rotating plate 704 rotates, the clamping and stabilizing mechanism 8 can be driven to rotate. The hydraulic cylinder 3 is started, and the output end of the hydraulic cylinder 3 extends to drive the connecting column 5 to move in the direction of the clamping and stabilizing mechanism 8, and then the connecting column 5 can drive the extruder 703 to rotate. The pressure plate 12 moves toward the clamping and stabilizing mechanism 8, and the valve is tightly pressed against the clamping and stabilizing mechanism 8 by using the squeezing plate 12. At this time, the gas in the installation box 702 enters the interior of the nozzle 709 through the ventilation hose 710, and can spray high-pressure gas through the nozzle 709. At this time, the hydraulic rod 706 is started, and the output end of the hydraulic rod 706 is retracted, thereby driving the connecting bent rod 707 to move to the side away from the clamping and stabilizing mechanism 8. The connecting bent rod 707 can drive the sliding block 708 and the nozzle 709 to move to the side of the valve on the clamping and stabilizing mechanism 8, and then the nozzle 709 can be moved to align with the inner side of the valve. At this time, the rotating plate 704 rotates, thereby driving the clamping and stabilizing mechanism 8 to rotate.The mounting plate 705 is driven to rotate by the clamping stabilizing mechanism 8, and the mounting plate 705 can drive the jet head 709 to rotate after the rotation. Since the clamping stabilizing mechanism 8 is pressed against the clamping stabilizing mechanism 8 by the squeezing disk 12, the valve will not rotate and the valve will be opened. Since the jet head 709 on the side away from the mounting frame 2 can spray high-pressure gas and rotate around the valve, the impurities in the valve can be blown out, and the jet head 709 is driven to move from the outside of the valve to the inside, or from the inside of the valve to the outside, by the retraction and extension of the output end of the hydraulic rod 706. After the jet head 709 on the side away from the mounting frame 2 rotates around the valve several times, the hydraulic cylinder 3 is started again, so that the input end of the hydraulic cylinder 3 is retracted, so that the other end of the valve can be exposed. At this time, the jet head 709 close to the mounting frame 2 will also spray high-pressure gas and completely clean the impurities inside the valve, and then the valve can be fully cleaned.

[0024] The clamping stabilizing mechanism 8 includes a mounting base ring 801, which can provide a mounting position. The outer side of the mounting base ring 801 is fixedly connected to the inside of the rotating plate 704. The mounting base ring 801 is rotatably connected to a mounting ring frame 802 on one side close to the mounting frame 2. The mounting ring frame 802 provides a mounting position. The inner side of the mounting ring frame 802 is rotatably connected to a plurality of rotating sleeves 803. The inner side of the rotating sleeve 803 is slidably connected to a rotating arm 804. The rotating sleeve 803 can limit the movement of the rotating arm 804. The inner side of the rotating arm 804 is rotatably connected with a clamping rotating disk 805, which can be against the valve and will not drive the valve to rotate when the mounting ring frame 802 rotates. The side of the rotating plate 704 close to the mounting frame 2 is rotatably connected with a hydraulic push rod 806, which provides power to push the mounting ring frame 802 to rotate. The output end of the hydraulic push rod 806 is rotatably connected to the inner side of the mounting ring frame 802, and the inner side of the mounting base ring 801 is away from the mounting ring frame 802. The side of the valve is fixedly connected with a blocking plate 807, which can block the valve to prevent the valve from being pushed outward under the action of the hydraulic cylinder 3. The side of the rotating arm 804 away from the clamping rotating disk 805 is rotatably connected to the outside of the rotating plate 704. The inner side of the blocking plate 807 is provided with a fitting groove 808, which can provide a space for one of the spray heads 709 to slide. The side of the spray head 709 away from the ventilation hose 710 is slidably connected to the inside of the fitting groove 808. When the valve is pressure tested, first The valve is placed in the middle of the mounting ring frame 802, and the hydraulic push rod 806 is started at this time. The output end of the hydraulic push rod 806 extends out. Under the limit of the hydraulic push rod 806, the rotating plate 704 does not rotate, and the mounting ring frame 802 rotates, so that the rotating arm 804 can slide inside the rotating sleeve 803, and then the clamping rotating disk 805 on the rotating arm 804 can be gathered to the middle of the mounting ring frame 802, and then the valve can be clamped and fixed in the middle of the mounting ring frame 802.

[0025] Working principle: When the valve is pressure tested, the valve is first placed in the middle of the mounting ring frame 802. At this time, the hydraulic push rod 806 is started, and the output end of the hydraulic push rod 806 extends out. Under the limit of the hydraulic push rod 806, the rotating plate 704 will not rotate, and the mounting ring frame 802 rotates, so that the rotating arm 804 can slide inside the rotating sleeve 803, and then the clamping rotating disk 805 on the rotating arm 804 can be gathered to the middle of the mounting ring frame 802, and then the valve can be clamped and fixed in the middle of the mounting ring frame 802; After the valve is fixed to the middle of the clamping and stabilizing mechanism 8, the air pump 4 is started, and the output end of the air pump 4 generates airflow, which enters the interior of the ventilation pipe 9. At this time, the electric valve 11 on the ventilation pipe 9 is opened, and the high-pressure airflow in the ventilation pipe 9 enters the interior of the installation box 702, so that the impeller ring 703 can be driven to rotate by the high-pressure airflow. After the impeller ring 703 rotates, the rotating plate 704 can be driven to rotate. After the rotating plate 704 rotates, the clamping and stabilizing mechanism 8 can be driven to rotate, and the hydraulic cylinder 3 is started. The output end of the hydraulic cylinder 3 extends to drive the connecting column 5 to the clamping and stabilizing mechanism 8. The connecting rod 707 is moved in the direction of the clamping and stabilizing mechanism 8, and then the squeezing plate 12 can be driven to move in the direction of the clamping and stabilizing mechanism 8 through the connecting column 5, and the valve is tightly pressed against the blocking plate 807 by the squeezing plate 12. At this time, the gas in the installation box 702 will enter the interior of the spray head 709 through the ventilation hose 710, and can spray high-pressure gas through the spray head 709. At this time, the hydraulic rod 706 is started, and the output end of the hydraulic rod 706 is retracted, so that the connecting bent rod 707 can be driven to move to the side away from the clamping and stabilizing mechanism 8, and the connecting bent rod 707 can drive the sliding block 708. The nozzle 709 is moved toward one side of the valve on the clamping stabilizing mechanism 8, and then the nozzle 709 can be moved to align with the inner side of the valve. At this time, the rotating plate 704 rotates to drive the clamping stabilizing mechanism 8 to rotate, and the mounting plate 705 is driven to rotate by the clamping stabilizing mechanism 8. After the mounting plate 705 rotates, the nozzle 709 can be driven to rotate. Since the clamping stabilizing mechanism 8 is pressed against the blocking plate 807 by the extrusion disk 12, the valve will not rotate and the valve will be opened. Since the nozzle 709 on the side away from the mounting frame 2 can spray high-pressure gas, it can The hydraulic cylinder 3 is able to rotate around the valve, so as to blow out the impurities in the valve, and the output end of the hydraulic rod 706 is retracted and extended to drive the jet head 709 to move from the outside of the valve to the inside, or from the inside of the valve to the outside. After the jet head 709 far away from the mounting frame 2 rotates around the valve for several circles, the hydraulic cylinder 3 is started again to retract the input end of the hydraulic cylinder 3, so that the other end of the valve can be exposed. At this time, the jet head 709 close to the mounting frame 2 will also spray high-pressure gas to completely clean the impurities inside the valve, and then the valve can be fully cleaned; When the valve is pressure tested, the valve is closed and the hydraulic cylinder 3 is started. After the output end of the hydraulic cylinder 3 is extended, the connecting column 5 is driven to move toward one side of the clamping and stabilizing mechanism 8, and the extrusion plate 12 is driven to move toward one side of the clamping and stabilizing mechanism 8, so that the extrusion plate 12 can be pressed against the valve, and the pressure of the valve housing can be tested by the hydraulic cylinder 3. After the pressure test of the valve housing is completed, if the valve is not damaged, the electric valve 11 on the ventilation main pipe 9 is closed, and the electric valve 11 on the ventilation branch pipe 10 is opened, so that the gas in the ventilation main pipe 9 can enter the ventilation pipe 10. The inside of the branch pipe 10 is entered through the ventilation branch pipe 10, and the inside of the tail pipe 616 is entered through the tail pipe 616 into the inside of the mounting pipe 601, and the gas is used to push the piston plate 604 to move to the side away from the mounting frame 2. When the piston plate 604 slides past one end of the connecting air pipe 614, the gas enters the inside of the airbag 613 through the connecting air pipe 614, so that the airbag 613 can be blown up, and the inflated airbag 613 can be tightly pressed against the inside of the valve. When the airbag 613 presses against the inside of the valve, the gas will no longer enter the inside of the connecting air pipe 614. At this time, The gas will push the piston plate 604 to move to the side away from the mounting bracket 2 again. After the piston plate 604 passes through the air outlet hole 603, the gas will quickly pass through the air outlet hole 603 into the inside of the branch air outlet pipe 602, and then enter the inside of the valve through the branch air outlet pipe 602. Since the airbag 613 swells, a closed space is formed between the airbag 613 and the inside of the valve. Therefore, after the branch air outlet pipe 602 releases gas into the closed space, if the valve is well sealed, the pressure gauge 13 will not change. If the valve leaks, the reading of the pressure gauge 13 will change continuously. When the airbag 613 needs to be pulled out of the valve, the pressing column 611 is pressed downward. After the pressing column 611 moves downward, it can drive the sliding plug plate 608 to move downward, and then drive the plug column 609 to move into the installation tube 606, so that the gas inside the airbag 613 enters the connecting air pipe 614 and enters the installation tube 606 through the connecting branch pipe 615. At this time, the gas inside the airbag 613 will be discharged through the exhaust hole 610, so the airbag 613 will deflate, and then the hydraulic cylinder 3 can be used to generate power to pull the airbag 613 out of the valve.
