Description

Technical Field

[0001] The invention relates to the field of pump and valve detection equipment, and in particular to a pump and valve micro-leakage detection and positioning device. Background Art

[0002] Pumps and valves are one of the commonly used equipment on ships. Pumps and valves are valves connected and fixed on the pump body. After the valves are produced, they need to be inspected. During the inspection, leakage needs to be detected and located. The existing high-precision filling devices used for valve detection need to use a fixing mechanism to fix the position of the valve when filling the valve to prevent the valve from moving due to excessive water pressure during the filling process, which affects the valve sealing detection.

[0003] According to the patent document with the existing announcement number CN217358902U, a high-precision filling device for valve detection is disclosed, which includes a device base, a filling mechanism is arranged on the top of the device base, a workbench is also placed on the top of the device base, and a fixing mechanism for fixing the valve is arranged on the side of the workbench away from the device base, and the fixing mechanism includes two lugs fixedly connected to the outside of the device base, and a rotating rod is rotatably connected between the two lugs. When this technical solution is in use, through the coordinated use of the filling mechanism and the fixing mechanism, the two clamping blocks can firmly clamp and fix the valve when the filling mechanism fills the valve to detect its sealing. With respect to the above technical solution, although this solution realizes the fixation of the valve, it cannot complete the rotational movement of the valve when fixing, thereby failing to complete the multi-faceted detection and marking of the leakage point, which is inconvenient when in use. Summary of the invention

When in use, the pushing mechanism pushes the annular seat and the active cone seat to move, and the active cone seat pushes one end of the valve body onto the passive cone seat. The valve body is squeezed and fixed under the push of the pushing mechanism. Later, the valve body rotates under the drive of the driving motor. The rotation of the valve body enables the valve body at different positions to cooperate with the sound sensors on the fixed frame and the movable frame to detect and mark the leakage points.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a pump valve micro-leakage detection and positioning device, including a base, a fixed seat welded on the base, a driving motor and a pushing mechanism fixedly installed on one end of the fixed seat, the pushing mechanism fixedly installed on both sides of the driving motor, a lifting mechanism fixedly installed on the top of the fixed seat, a fixed frame fixedly installed on one end of the lifting mechanism, a sliding groove is opened on the base, a support rod is movably installed inside the sliding groove, a movable seat is movably installed on the support rod, a slot is opened on the movable seat, and the support rod is movably installed inside the slot.

The rotation of the valve body makes the valve body at different positions cooperate with the sound sensors on the fixed frame and the movable frame to detect and mark the leakage points.

[0016] The invention relates to a pump valve micro-leakage detection and positioning device. After the movable seat drives the support rod to enter the interior of the slide slot, the support rod and the movable frame are moved out as a whole. After the movable frame is moved out, the valve body is installed between the movable frames for support. The movable seat is pushed later to facilitate moving the valve body to a fixed position. After the support rod and the movable frame are returned to their positions, the position of the movable frame at the bottom of the valve body is controlled under the push of the displacement mechanism, so that the fixed frame and the movable frame are offset left and right to support the valve body. In addition, during detection, the displacement mechanism drives the movable frame to move, and the valve body rotates when the movable frame moves. The detection of the valve body at different positions is completed through the sound sensor on the movable frame.

[0017] This pump valve micro-leakage detection and positioning device injects a small amount of detection liquid into the valve body through a water pump, and then gas is introduced into the valve body again. The gas pressurizes the valve body. After the pressurization is completed, the air pressure is observed through an external pressure gauge to observe whether the air pressure changes, thereby completing the preliminary detection. The liquid inside the valve body is pushed to flow under the squeezing of the gas. When a leakage point appears on the valve body, the liquid is discharged from the leakage point, which facilitates the rapid marking and finding of the problem point.

[0024] When the device is in use, the displacement mechanism 2 is started to push the support rod 16 to move inside the limit groove 17, and the support rod 16 moves to one end of the slide groove 10, and the movable seat 11 is dragged to slide inside the slide groove 10 through the support rod 16. After the movable seat 11 moves, the movable frame 18 moves outward, and the two ends of the connecting part of the valve body 31 are installed on the movable frame 18 for support, which is convenient for the early installation of the valve body 31. After the valve body 31 is installed on the movable frame 18, the movable seat 11 is pushed back to its position. After the movable seat 11 is back to its position, the displacement mechanism 2 is started to push the support rod 16 to be misaligned with the slide groove 10. After the support rod 16 is misaligned with the slide groove 10, the movable seat 11 is limited and fixed, and the pushing mechanism 5 is started to push the ring seat 24 and the active cone seat 23 to move and contact one end of the valve body 31. As the active cone seat 23 pushes one end of the valve body 31 to contact the passive cone seat 12, the valve body 31 is clamped and fixed.

When a leak occurs on the valve body 31, the liquid is discharged from the leak, which facilitates the rapid marking and finding of the problem point. When the gas is injected, the displacement mechanism 2 is started to push the support rod 16 to move inside the slot 13, and the movable frame 18 is at the connection part of the valve body 31. When the movable frame 18 moves, the driving motor 4 is started to drive the active cone seat 23 to rotate. When the active cone seat 23 rotates, the valve body 31 and the connecting part rotate. Under the rotation, the valve body 31 at different positions moves in a circle on the movable frame 18. When the movable frame 18 moves, the sound sensor 19 performs sound detection on the leakage point. After the sound sensor 19 moves to the leakage point, the sound from the leakage point is greater than the noise collected when the movable frame 18 is moving all the time, thereby completing the secondary detection of the leakage point. When the leakage point is found, the liquid inside the valve body 31 forms bubbles and sprays out from the leakage point for marking.
