Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of valve testing devices for marine valve processing, and in particular to a valve testing device for marine valve processing. Background Technology
[0002] Ultrasonic valve internal leakage detectors utilize advanced ultrasonic detection technology. By emitting and receiving high-frequency ultrasonic signals, they penetrate the valve material and accurately capture minute acoustic changes caused by internal leakage. This non-invasive detection method allows for rapid assessment of internal leakage without disassembling the valve, significantly improving detection efficiency and accuracy.
[0003] The inventors discovered during routine use of the ultrasonic valve internal leakage detector that when testing the valve, it is necessary to hold the probe in one hand and the detector in the other. Since the probe and the detector are connected by a cable, excessive pulling force during testing can easily cause the probe and the detector to separate, thus causing problems. Summary of the Invention
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a valve testing device for marine valve processing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a valve testing device for marine valve processing, comprising a testing instrument, a connection port fixedly connected to the top of the testing instrument, a connecting wire inserted inside the connection port, an ultrasonic probe fixedly connected to one end of the connecting wire, a limiting device fixedly connected to the top of the connection port, the limiting device comprising an arc-shaped plate disposed on the top of the connection port, a ring disposed on the surface of the arc-shaped plate, a slope formed on the inner wall of the ring, a threaded groove formed on the surface of the arc-shaped plate, and a threaded thread fixedly connected to the surface of the slope.
[0006] The effect achieved by the above components is that, under the action of the ring, thread and groove, the arc plate can move towards the center position, thereby fixing the connecting line inside the connecting port, thus achieving the function of limiting.
[0007] Preferably, a baffle is fixedly connected to the side of the arc-shaped plate, the baffle is located on the side of the arc-shaped plate away from the connection port, and a retaining strip, which is a rubber strip, is fixedly connected to the inner wall of the arc-shaped plate.
[0008] The above components achieve the following effects: the locking strip prevents the connecting wire from easily slipping out between the curved plates, thus achieving a fixing effect; the baffle prevents the ring from slipping off the surface of the curved plate.
[0009] Preferably, a retaining ring, which is a rubber ring, is fixedly connected to the inner wall of the connection port.
[0010] The effect achieved by the above components is that, under the action of the retaining ring, the connecting wire can be locked inside the connecting port, thereby achieving the function of limiting movement.
[0011] Preferably, a circular plate is fixedly connected to the surface of the connection port, and the circular plate is disposed below the circular ring.
[0012] The aforementioned components achieve the following effects: Under the action of the circular plate, the ring will not slip off the surface of the arc-shaped plate, thus achieving a limiting function. When it is necessary to limit the connection wire, the connection wire is inserted into the inside of the connection port. Under the action of the retaining ring, the connection wire can be locked inside the connection port, thus achieving a limiting function. Rotating the ring, under the action of the screw groove and thread, causes the ring to press the arc-shaped plate towards the center, thereby locking the connection wire inside the connection port through the retaining strip. Under the action of the baffle, the ring will not slip off the surface of the arc-shaped plate. Under the action of the circular plate, the ring will not slip off the surface of the arc-shaped plate, thus achieving a limiting function.
[0013] Preferably, the detector is provided with a winding device on its side, the winding device including an L-shaped rod fixedly connected to the side of the detector, and the connecting wire is wound around the surface of the L-shaped rod.
[0014] The effect achieved by the above components is that, under the action of the L-shaped rod, the connecting wire can be wound up on the surface of the L-shaped rod, thereby achieving the winding effect.
[0015] Preferably, a rectangular plate is fixedly connected to the side of the L-shaped rod, and a triangular strip is fixedly connected to the side of the rectangular plate.
[0016] The effect achieved by the above components is that, under the action of the rectangular plates, the connecting wires can be locked between the rectangular plates, and under the action of the triangular strips, the connecting wires will not slip out from between the rectangular plates.
[0017] Preferably, a strap is fixedly connected to the top of the L-shaped rod, and the strap secures the connecting lines on the surface of the L-shaped rod.
[0018] The effect achieved by the above components is that the connecting line wound on the surface of the L-shaped rod is fixed by the straps, thereby achieving the function of fixation.
[0019] Preferably, the side of the strap is fixedly connected with Velcro, and the Velcro is attached together.
[0020] The effect achieved by the above components is as follows: the Velcro allows the straps to be easily attached together. When it is necessary to wind up the connecting wire, the connecting wire is wrapped around the surface of the L-shaped rod. After the connecting wire is caught between the rectangular plates, the triangular strip prevents the connecting wire from slipping off between the rectangular plates. After the connecting wire is completely wrapped around the surface of the L-shaped rod, the straps are wrapped around the surface of the connecting wire, and the Velcro is attached together, thereby fixing the connecting wire to the surface of the L-shaped rod, thus achieving the winding effect.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting a limiting device, when it is necessary to limit the connection wire, the connection wire is inserted into the inside of the connection port. Under the action of the retaining ring, the connection wire can be locked inside the connection port, thereby achieving the limiting function. Rotating the ring, under the action of the screw groove and the thread, the ring presses the arc plate towards the center, thereby locking the connection wire inside the connection port through the retaining strip. Under the action of the baffle, the ring will not slip off the surface of the arc plate. Under the action of the circular plate, the ring will not slip off the surface of the arc plate, thereby achieving the limiting function. This solves the problem that the detector is prone to separation from the probe due to excessive pulling force. Attached Figure Description

[0030] Example 1, such as Figure 1-2 A valve testing device for marine valve processing includes a testing instrument 1. A connection port 5 is fixedly connected to the top of the testing instrument 1. A connecting wire is inserted inside the connection port 5. An ultrasonic probe 4 is fixedly connected to one end of the connecting wire. A limit device 2 is fixedly connected to the top of the connection port 5.
[0031] The instrument works by capturing the ultrasonic energy generated by a leak using a high-frequency sensor, converting it into audible sound waves or electrical signals, typically displayed in decibels. During detection, multiple readings are taken upstream and downstream of the valve. The location of the leak is determined by comparing the signal strength differences between upstream and downstream: if the downstream reading is significantly higher than the upstream reading, a leak is present.
[0032] Reference Figure 3-4 The limiting device 2 includes an arc-shaped plate 21 disposed at the top of the connection port 5. A ring 22 is disposed on the surface of the arc-shaped plate 21. A slope is formed on the inner wall of the ring 22. A threaded groove 27 is formed on the surface of the arc-shaped plate 21. A thread is fixedly connected to the surface of the slope. A baffle 24 is fixedly connected to the side of the arc-shaped plate 21. The baffle 24 is disposed on the side of the arc-shaped plate 21 away from the connection port 5. A retaining strip 25 is fixedly connected to the inner wall of the arc-shaped plate 21. The retaining strip 25 is a rubber strip. A retaining ring 26 is fixedly connected to the inner wall of the connection port 5. The retaining ring 26 is a rubber ring. A circular plate 23 is fixedly connected to the surface of the connection port 5. The circular plate 23 is disposed below the ring 22.
[0033] Working principle: When it is necessary to limit the connection wire, the connection wire is inserted into the connection port 5. Under the action of the retaining ring 26, the connection wire can be locked inside the connection port 5, thereby achieving the limiting function. Rotating the ring 22, under the action of the screw groove 27 and the thread, the ring 22 presses the arc plate 21 towards the center, thereby locking the connection wire inside the connection port 5 through the retaining strip 25. Under the action of the baffle 24, the ring 22 will not slip off the surface of the arc plate 21. Under the action of the circular plate 23, the ring 22 will not slip off the surface of the arc plate 21, thereby achieving the limiting function.
[0034] Reference Figure 5-6The detector 1 is provided with a winding device 3 on its side. The winding device 3 includes an L-shaped rod 31 fixedly connected to the side of the detector 1. The connecting wire is wound around the surface of the L-shaped rod 31. A rectangular plate 32 is fixedly connected to the side of the L-shaped rod 31. A triangular strip 33 is fixedly connected to the side of the rectangular plate 32. A strap 34 is fixedly connected to the top of the L-shaped rod 31. The strap 34 fixes the connecting wire on the surface of the L-shaped rod 31. A Velcro 35 is fixedly connected to the side of the strap 34. The Velcro 35 are attached together.
[0035] Working principle: When it is necessary to wind up the connecting wire, the connecting wire is wrapped around the surface of the L-shaped rod 31. After the connecting wire is caught between the rectangular plates 32, the triangular strip 33 prevents the connecting wire from slipping off between the rectangular plates 32. After the connecting wire is completely wrapped around the surface of the L-shaped rod 31, the binding tape 34 is wrapped around the surface of the connecting wire, and the Velcro 35 is attached together, thereby fixing the connecting wire to the surface of the L-shaped rod 31, thus achieving the winding effect.
