Description

Technical Field

[0001] The present application relates to the technical field, and in particular to an electrically controlled water injection coupling device in a phased array ultrasonic detection system. Background Art

[0002] Phased array ultrasonic testing technology is a nondestructive testing technology based on the principle of ultrasonic testing. It detects and evaluates internal defects of objects by controlling the emission and reception of ultrasonic waves. Phased array ultrasonic testing methods usually use water as a coupling agent and can be divided into two forms: water immersion and water spray coupling. The water spray coupling method has the advantages of convenience, speed, large detection range, and avoidance of long-term immersion of workpieces, and is widely used.

[0003] However, when using the water spray coupling detection method, the water column sprayed from the nozzle is easily affected by the water supply pressure. During the detection process, changes in the water supply pressure will directly cause the shape and integrity of the water column to become unstable, thereby causing the ultrasonic sound field in the water column to become disordered, and the ultrasonic energy cannot remain concentrated, so that the collected test data cannot achieve the expected effect or cannot meet the standard's requirements for detection, the accuracy of the detection becomes low, and there are obvious shortcomings. Utility Model Content

[0004] In order to improve the detection accuracy of phased array ultrasonic detection, the present application provides an electrically controlled water injection coupling device in a phased array ultrasonic detection system.

[0005] The electric-controlled water injection coupling device in the phased array ultrasonic detection system provided in the present application adopts the following technical solution:

[0006] An electrically controlled water injection coupling device in a phased array ultrasonic detection system comprises a water supply component, a connecting water pipe and a nozzle body. The water supply component comprises a water tank and a water supply pump. The water supply pump is arranged on the connecting water pipe. The water inlet end of the connecting water pipe is connected to the inside of the water tank, and the water outlet end is connected to the nozzle body. A pressure stabilizer is arranged on the connecting water pipe, and the pressure stabilizer is used to maintain the water pressure in the connecting water pipe stable.

[0007] By adopting the above technical scheme, when a water spray coupling detection method is adopted, the water supply pump draws water from the water tank into the connecting water pipe. The water flow in the connecting water pipe always maintains a constant water pressure under the action of the pressure stabilizer. The shape and integrity of the water column when the stable water flow is sprayed out from the nozzle body remain stable, and the ultrasonic sound field in the water column remains stable, so that the ultrasonic wave can be stably converged at the point to be detected, thereby improving the detection accuracy of the phased array ultrasonic detection.

[0008] Optionally, the pressure stabilizing component is a pressure regulating valve, which is installed at one end of the connecting water pipe close to the water supply component, and the pressure regulating valve is electrically connected to a control system.

[0009] By adopting the above technical solution, during detection, a predetermined pressure value is first input into the control system. When the water supply pressure provided by the water supply pump is higher or lower than the preset value, the control system automatically starts the control component of the pressure regulating valve to adjust the water flow pressure passing through the pressure regulating valve to the preset pressure value, so that the water column sprayed from the nozzle body always remains in a stable state.

[0010] Optionally, a solenoid valve is provided on the connecting water pipe, the solenoid valve is electrically connected to a control system, and the solenoid valve is used to control the on-off of a water channel in the connecting water pipe.

[0011] By adopting the above technical solution, the on-off of the water channel is automatically controlled by the solenoid valve, so that it can be automatically opened when detecting and closed when not detecting, thereby realizing the automatic operation of the device.

[0012] Optionally, a manual valve is provided on the connecting water pipe, and the manual valve is used to control the on-off of the water channel in the connecting water pipe.

[0013] By adopting the above technical solution, when the solenoid valve is damaged or cannot work normally due to other factors, the inspection personnel can manually turn the manual valve to realize the connection and disconnection of the connecting pipeline. The setting of the manual valve improves the reliability of the device.

[0014] Optionally, the water outlet end of the connecting water pipe is connected to a diverter, the water outlet end of the diverter is connected to a plurality of water outlet pipes, and the nozzle body is connected to the water outlet ends of the water outlet pipes.

[0015] By adopting the above technical solution, the setting of the diverter can enable the device to provide stable water coupling medium for multiple locations in the phased array ultrasonic detection system at the same time, expanding the scope of action of the electrically controlled water injection coupling device, thereby further improving the accuracy of detection.

[0016] Optionally, a water filling chamber connected to the water outlet pipe is provided inside the nozzle body, a probe end cover is provided at one end of the nozzle body, and a water outlet nozzle is provided at the other end, an ultrasonic probe is provided on the probe end cover, a water screen is provided inside the water filling chamber, and a plurality of water holes extending along the length direction of the water screen are provided on the water screen.

[0017] By adopting the above technical solution, the water flowing out from the water outlet joint enters the water filling chamber, and the water flow is divided into multiple small water flows by multiple water holes at the water screen. This arrangement reduces the impact of the change in water flow direction on the shape of the water column. At the same time, the evenly distributed water holes can stabilize the shape of the water flow and reduce the generation of bubble cavities in the water column, thereby further ensuring that the shape and integrity of the water column sprayed from the nozzle are stable, thereby further improving the accuracy of the detection.

[0018] Optionally, a water outlet joint is provided at the water outlet end of the water outlet pipe, a water inlet joint is provided on the nozzle body, and the water inlet joint is threadedly connected to the water outlet joint.

[0019] By adopting the above technical solution, the detachable connection of the nozzle body on the water outlet pipe is achieved through the threaded cooperation between the water inlet joint and the water outlet joint, thereby facilitating the inspection personnel to replace and maintain the nozzle body.

[0020] Optionally, a water outlet is provided on the water outlet nozzle, a cross section of the water outlet nozzle gradually decreases in a direction toward the water outlet, and a cross section of the water outlet is rectangular.

[0021] By adopting the above technical solution, the cross-sectional area of ​​the water outlet nozzle gradually decreases toward the water outlet, and the water flow will shrink and flow toward the middle along the inner wall of the water outlet nozzle during the flow inside the water outlet pipe, so that the water flow passing through the water screen can be concentrated at the water outlet and fill the water outlet, reducing the adverse effect of the nozzle shape on the stability of the water column.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The present application provides a pressure stabilizer, so that the water flow in the connected water pipe always maintains a constant water pressure under the action of the pressure stabilizer, and the shape and integrity of the water column when the stable water flow is sprayed from the nozzle body remain stable, and the ultrasonic sound field in the water column remains stable, so that the ultrasonic wave is stably converged at the place to be detected, thereby improving the detection accuracy of the phased array ultrasonic detection;

[0024] 2. The present application provides a solenoid valve and a manual valve to realize the automatic operation of the water injection coupling device through the solenoid valve, and the manual valve is provided to improve the reliability of the device;

[0025] 3. In the present application, a water screen and water holes are arranged so that the water flow is divided into multiple small water flows by multiple water holes at the water screen. Such arrangement reduces the impact of changes in water flow direction on the shape of the water column. At the same time, the evenly distributed water holes can stabilize the shape of the water flow and reduce the generation of bubble cavities in the water column, thereby further ensuring that the shape and integrity of the water column sprayed from the nozzle are stable, thereby further improving the accuracy of the detection.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses an electrically controlled water injection coupling device in a phased array ultrasonic detection system.

[0032] Reference Figure 1 An electrically controlled water injection coupling device in a phased array ultrasonic detection system includes a water supply component 000, a voltage stabilizer 100 and a connecting water pipe 200. The water supply component 000 includes a water tank 001 and a water supply pump 002. Water for coupling is stored in the water tank 001. The water supply pump 002 and the voltage stabilizer 100 are sequentially installed on the connecting water pipe 200 along the flow direction of the water flow. The water inlet end of the connecting water pipe 200 is connected to the inside of the water tank 001. The connecting water pipe 200 is sequentially installed with a solenoid valve 300, a manual valve 400, a diverter 500 and a nozzle body 600 along the flow direction of the water flow. The voltage stabilizer 100 is a pressure regulating valve 101. The pressure regulating valve 101 and the solenoid valve 300 are both electrically connected to the control system. The pressure regulating valve 101 is controlled by the control system to ensure the stability of the water pressure in the connecting water pipe 200. The control system controls the opening and closing of the solenoid valve 300.

[0033] During the inspection, the inspector inputs a predetermined pressure value into the control system, and then the control system controls the solenoid valve 300 and the water supply pump 002 to open, and the water supply pump 002 draws water from the water tank 001 into the connecting water pipe 200. When the water supply pressure provided by the water supply pump 002 is higher or lower than the preset value, the control system automatically starts the control component of the pressure regulating valve 101, and adjusts the water flow pressure passing through the pressure regulating valve 101 to the preset pressure value, so that the water flow in the connecting water pipe 200 maintains a constant water pressure, the shape and integrity of the water column when the stable water flow is sprayed out from the nozzle body 600 remain stable, and the ultrasonic sound field in the water column remains stable, so that the ultrasonic wave is stably converged at the place to be inspected, thereby improving the detection accuracy of the phased array ultrasonic detection. When the detection is completed, the control system automatically controls the solenoid valve 300 and the water supply pump 002 to close, and the water path in the connecting water pipe 200 is disconnected.

[0034] Reference Figure 1 The manual valve 400 is arranged at one end of the solenoid valve 300 close to the nozzle body 600. When the solenoid valve 300 is damaged or cannot work normally due to other factors, the inspector can manually turn the manual valve 400 to open and close the connecting pipeline. The setting of the manual valve 400 improves the reliability of the device.

[0035] Reference Figure 1 and Figure 2 , the diverter 500 is installed at the water outlet end connected to the water pipe 200, and a plurality of water outlet pipes 501 are connected on the diverter 500. In the present embodiment, the number of the water outlet pipes 501 is two, and the water outlet end of the water outlet pipe 501 is connected with a water outlet joint 502, and the nozzle body 600 is connected with a water inlet joint 601, and the water inlet joint 601 is threadedly connected to the water outlet joint 502. A water filling chamber 700 connected with the water inlet joint 601 is provided inside the nozzle body 600. After passing through the water inlet joint 601, the water flows into the water filling chamber 700. A probe end cover 602 is detachably installed at one end of the nozzle body 600, and a water outlet nozzle 603 is integrally formed at the other end. An ultrasonic probe 800 is installed on the probe end cover 602. In the present embodiment, the probe end cover 602 and the nozzle body 600 are detachably installed by threaded cooperation of bolts and nuts, and the ultrasonic probe 800 is arranged with a probing direction toward the water outlet nozzle 603.

[0036] During inspection, the inspector can install the nozzle body 600 according to the number of positions that need to be inspected. When the nozzle body 600 needs to be installed, the inspector holds the nozzle body 600 to align the water inlet joint 601 with the water outlet joint 502, and then rotates the water inlet joint 601 to thread the water inlet joint 601 onto the water outlet joint 502. During inspection, water flowing to the water outlet joint 502 enters the water filling chamber 700 through the water inlet joint 601, and is ejected through the water outlet nozzle 603 during the flow in the water filling chamber 700, and finally ejects a water column.

[0037] Reference Figure 2 and Figure 3 A water screen 900 is provided inside the nozzle body 600. The water screen 900 is fixedly installed inside the nozzle body 600 in a ring shape. The water screen 900 is sleeved on the end of the ultrasonic probe 800 away from the probe end cover 602. A plurality of water holes 901 are evenly distributed on the water screen 900, and the water holes 901 extend along the length direction of the water screen 900.

[0038] After the water flows into the water filling chamber 700, the direction of the water flow changes and the stability of the water flow will be reduced. When the water flows through the water hole 901 of the water screen 900, the water flow is divided into multiple small water flows by the water hole 901. This arrangement reduces the impact of the change in the direction of the water flow on the shape of the water column. At the same time, the evenly distributed water holes 901 can stabilize the shape of the water flow and reduce the generation of bubble cavities in the water column, thereby further ensuring that the shape and integrity of the water column sprayed from the nozzle are stable, thereby further improving the accuracy of the detection.

[0039] Reference Figure 3 A water outlet 604 is provided at one end of the water outlet nozzle 603 away from the probe end cover 602 . The cross section of the water outlet nozzle 603 gradually decreases along the direction of the water outlet 604 . The cross section of the water outlet 604 is rectangular.

[0040] After passing through the water hole 901, the water flow converges in the water outlet nozzle 603. During the flow, the water flow will shrink and flow toward the middle along the inner wall of the water outlet nozzle 603, so that the water flow can be concentrated at the water outlet 604 and fill the water outlet 604. The water flow guided by the water outlet nozzle 603 eventually forms a stable water column and is sprayed at the position to be detected. At the same time, the ultrasonic probe 800 performs ultrasonic detection on the position to be detected.

[0041] The implementation principle of the electrically controlled water injection coupling device in a phased array ultrasonic detection system of an embodiment of the present application is as follows: during detection, the detection personnel input a predetermined pressure value into the control system, and then the control system controls the solenoid valve 300 and the water supply pump 002 to open, and the water supply pump 002 draws water from the water tank 001 into the connecting water pipe 200. When the water supply pressure provided by the water supply pump 002 is higher or lower than the preset value, the control system automatically starts the control component of the pressure regulating valve 101, and adjusts the water flow pressure passing through the pressure regulating valve 101 to the preset pressure value, so that the water flow in the connecting water pipe 200 maintains a constant water pressure, the shape and integrity of the water column when the stable water flow is sprayed out from the nozzle body 600 remain stable, and the ultrasonic sound field in the water column remains stable, so that the ultrasonic wave is stably converged at the place to be detected, thereby improving the detection accuracy of the phased array ultrasonic detection. When the detection is completed, the control system automatically controls the solenoid valve 300 and the water supply pump 002 to close, and the water path in the connecting water pipe 200 is disconnected.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
