Description

Technical Field

[0001] The invention relates to the technical field of valve ultrasonic detection, in particular to an intelligent valve inner wall ultrasonic detection device. Background Art

[0002] As an important device for fluid control, valves are widely used in many fields such as petroleum, chemical industry, and electric power. The valve internal leakage detector using ultrasonic technology is used to detect valve internal leakage and hydraulic system leakage fault finding system when it is online to detect valve internal blockage or leakage.

[0003] At present, the existing intelligent valve inner wall ultrasonic detection equipment has the following shortcomings in use: First, during the detection, after the detection position is determined by personnel, the handheld contact sensor will first push the connected ultrasonic probe against the upstream pipeline of the valve to listen to the leakage signal, and determine the system environmental ultrasonic value according to the data reading displayed on the display screen and record it to determine whether there is a leakage. Then, the contact sensor will be pushed against different positions of the downstream pipeline to confirm the leakage point. Although this detection operation is convenient, it is very subjective and has poor stability. In actual operation, different types of valves, such as gate valves, stop valves, ball valves, etc., need to be determined based on experience due to their different nominal diameters, inlet pressures, opening heights, and outlet distances. Therefore, different detection results will be caused. If you simply select a sampling point with a certain diameter section downstream for detection, it may cause misjudgment, because this method does not fully consider the type of valve, working conditions and other factors, and because of the different use environments of the valves, for those valves with peeling, bulging, and rusting of the outer shell, although there is a simple protection of the protective film during the detection probe resistance operation, if the film is broken after long-term use and is not discovered in time, it may cause damage to the piezoelectric chip. The probe is affected by the surrounding environment, which will also reduce the accuracy of the detection.

[0004] Therefore, those skilled in the art provide an intelligent valve inner wall ultrasonic detection device to solve the problems raised in the above background technology. Summary of the invention

If the sampling points of a certain pipe diameter section downstream are simply selected for detection, misjudgment may be caused.

[0033] According to the above technical solution, the switch of the first micro servo motor 4 is turned on from an external controller. After the first micro servo motor 4 is running, it can drive the reciprocating screw 6 to rotate, thereby driving the main guide block 18 to rise first and slide on the inner side of the main ring frame 1. During the sliding process, the outer frame assembly 555 is driven to move, thereby driving the auxiliary sealing assembly 553 to move to the upstream pipeline of the valve. The switch of the micro telescopic rod 24 is turned on from the external controller, so that the adjustment slide 25 is driven to slide in the main guide block 18 and push the arc-shaped adjustment frame 3 to move a predetermined distance to the front end. The second magnetic suction head 12 that is energized is adsorbed on the outer surface of the measuring position of the valve, which is beneficial to the high vibration protection and sealing effect of the probe when it is working, and ensures the efficiency and quality of the overall ultrasonic detection of the inner wall of the intelligent valve.

[0035] According to the above technical solution, the external detector is installed on one of the adsorption frames 7 according to the height. At this time, the first magnetic heads 11 on both sides are firstly adsorbed and tightly attached to the valve, and drive the pop-up rod 46 to move and tighten the first spring 10 on the mounting strip 9, thereby driving the two mounting strips 9 to move in the direction of approaching each other.

During the movement of the rack plate 33, the push plate 35 can be driven to move to one side first, and the magnetic plate 36 on one side of the movement direction can be driven to move, and the sliding head 43 is further driven to slide in the limiting slide rail 45. When resetting, the just moved magnetic plate 36 contacts the blocking block 37, thereby disengaging from the push plate 35, so that the magnetic plate 36 on the other side is driven to move in the same direction, thereby adjusting the horizontal position of the detection, and displaying the distance between the upstream pipeline point and the downstream pipeline point of the valve detection through the measuring scale 23 set on the main ring frame 1, which is conducive to selecting more suitable upstream and downstream detection points during ultrasonic detection of the valve, so as to improve the accuracy of the detection process and accurately judge the valve condition.

[0038] The embodiment of the present invention also provides an intelligent valve inner wall ultrasonic detection device, and the specific working principle includes the following steps:

At this time, the first magnetic heads 11 on both sides are firstly adsorbed and tightly attached to the valve, and drive the pop-up rod 46 to move on the installation strip 9 to tighten the first spring 10, thereby driving the two installation strips 9 to move towards each other. In this operation, the contact amount between the multiple first magnetic heads 11 and the outer wall of the valve can be guaranteed. By limiting the first limit opening 20 by the first pin, the length of the guide rod 19 extending out of the installation strip 9 can be adjusted to improve the adaptability to different valves, and further drive the linkage arm 21 to rotate and then pull the linkage rod 8 to move, and the linkage After the moving rod 8 moves, it drives the limiting block 29 to slide smoothly on the outer surface of the limiting rod 27 and the limiting groove 26, and fixes the final position by inserting the second pin into the second limit opening 28. The external installation mechanical arm is controlled to lift and install the U-shaped support frame 2, and then the switch of the first micro servo motor 4 is turned on from the external controller. After the first micro servo motor 4 is running, it can drive the reciprocating screw 6 to rotate, thereby driving the main guide block 18 to rise and slide on the inner side of the main ring frame 1.

The second magnetic suction head 12 that is energized is adsorbed on the outer surface of the measuring position of the valve. By loosening the positioning pin 13, the sliding position of the conductive rod 38 on the arc-shaped rod 14 can be adjusted. After the telescopic probe 17 is extended in the rod frame ring seat 44, the front diaphragm disc 15 is driven to move toward the valve to contact and stick tightly. Under the movement of the front diaphragm disc 15, multiple connecting rods 42 can be driven to move simultaneously, so that the sealing cover 16 is driven to shrink in size, and the pressure cap 40 is further driven to compress the second spring 39 on the rod seat 41, so that the sealing cover 16 can form a sealed chamber around the detection position. When it is necessary to detect in the horizontal direction, When measuring different positions, it is necessary to control the second micro servo motor 31 to operate, thereby driving the gear 32 to rotate and drive the meshing rack plate 33 to move horizontally in the limiting groove 34. During the movement of the rack plate 33, it can drive the push plate 35 to move to one side first, and when moving, it drives the magnetic plate 36 on one side of the movement direction to move, and further drives the sliding head 43 to slide in the limiting slide rail 45. When resetting, the magnetic plate 36 that has just moved contacts with the blocking block 37, thereby disengaging from the push plate 35, so that the magnetic plate 36 on the other side moves in the direction, thereby adjusting the horizontal position of the detection, and displaying the distance between the upstream pipeline point and the downstream pipeline point of the valve detection through the measuring scale 23 set on the main ring frame 1.
