Description

Technical Field

[0001] The utility model relates to the technical field of valve detection, in particular to a detection device suitable for valves of different sizes. Background Art

[0002] Valves are pipe fittings used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveying medium (temperature, pressure, and flow). Based on their function, they can be divided into shut-off valves, check valves, and regulating valves. Valves are control components in fluid conveying systems, with functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion, or overflow pressure relief. Valves used in fluid control systems come in a wide variety of types and specifications, from the simplest shut-off valves to the various valves used in extremely complex automatic control systems. Valves are generally produced through a casting process. Cast valves cannot have sand holes or obvious defects, so quality inspection is required to test the surface flatness of the produced valves. In the existing technology, quality inspectors generally manually lift the valves. For smaller valves, quality inspectors can directly observe and inspect them. For larger valves, the inspectors will become fatigued from holding the valves for a long time, affecting the efficiency of valve inspection, which requires improvement. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems raised in the above background technology.

[0004] The utility model adopts the following technical solution: a detection device suitable for valves of different sizes, including a base, a bracket fixedly installed on the surface of the base, a motor fixedly installed on the surface of the bracket, a bidirectional screw fixedly installed on the output end of the motor, a first moving block and a second moving block threadedly connected on the surface of the bidirectional screw, the surfaces of the first moving block and the second moving block are both rotatably connected to a protective bin, a spring fixedly installed inside the protective bin, a connecting rod slidably connected inside the protective bin, a limiting rod fixedly installed on the surface of the connecting rod, a splint fixedly installed on the surface of the connecting rod, a rotating shaft fixedly installed on the surface of the protective bin, a turntable fixedly installed on the surface of the rotating shaft, and a turning handle fixedly installed on the surface of the turntable.

[0005] Preferably, a lighting lamp is fixedly mounted on the surface of the bracket, and a support foot is fixedly mounted on the bottom end of the base. Here, the lighting lamp can provide better brightness, making it easier for the quality inspector to observe the valve, and the support foot at the bottom end of the base can provide stability for the quality inspector when inspecting the valve, making the inspection device safer.

[0006] Preferably, a gasket is fixedly mounted on the surface of the clamping plate, and the material of the gasket is a silicone material. Here, the gasket is mounted on the surface of the clamping plate, and the gasket can reduce the squeezing damage of the clamping plate to the valve when in contact with the valve, thereby preventing the valve from being pinched and damaged.

[0007] Preferably, the connecting rod slides inside the protection chamber. Here, the connecting rod slides in the protection chamber to limit the clamping plate to prevent the clamping plate from loosening and sliding during rotation, and can also compress the spring to reduce damage to the valve caused by the clamping plate pressure.

[0008] Preferably, the rotating shaft rotates inside the bracket, and the length of the rotating shaft is greater than half the length of the bidirectional screw. Here, when the detection device is used, the valve needs to be fixed first. When the motor is turned on, it will drive the bidirectional screw to rotate, and then the clamping plate will clamp the valve. When inspecting the valve, the quality inspector needs to turn the handle and the turntable, so that the valve can be inspected in all directions. When the length of the rotating shaft is greater than half the length of the bidirectional screw, the rotating shaft has sufficient space to rotate.

[0009] Preferably, a fixed block is fixedly mounted on the surface of the base, a hydraulic pump is fixedly mounted on the surface of the fixed block, and a limit bracket is fixedly mounted on the output end of the hydraulic pump. Here, to make the valve more stable during testing, the hydraulic pump can be turned on. When the hydraulic pump rises, it can lift the valve, further stabilizing the valve.

[0010] Preferably, a groove is formed on the surface of the limit frame, and the shape of the groove is arc-shaped. Here, the arc-shaped groove can fit the valve more closely, making the valve more stable when rotating and more convenient for quality inspectors to detect.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the utility model, by arranging a base, a bracket, a motor, a two-way screw rod, a first moving block, a second moving block, a protective chamber, a spring, a connecting rod, a limit rod, a splint, a rotating shaft, a turntable, and a turning handle structure, when different valves are tested for flatness, the motor can be turned on, and when the first moving block and the second moving block converge with each other, the splint can clamp and fix the valve, and then by turning the turning handle, the flatness of the valve can be observed from multiple angles. When the splint fixes the valve, the connecting rod can compress the spring to reduce the pressure of the splint on the valve to prevent the valve from being clamped and damaged. By arranging a lighting lamp, a supporting foot, and a gasket structure, the lighting lamp can provide better brightness, which is convenient for quality inspectors to observe the valve. The supporting foot at the bottom of the base can provide stability for quality inspectors when detecting the valve, making the detection device safer. A gasket is installed on the surface of the splint, which can reduce the squeezing damage of the splint on the valve when the gasket contacts the valve, thereby preventing the valve from being clamped and damaged.

[0013] 2. In the present invention, by setting a fixed block, a hydraulic pump, a limit frame, and a groove structure, in order to make the valve more stable during inspection, the hydraulic pump can be turned on. When the hydraulic pump rises, the valve can be lifted up, further making the valve more stable. The arc-shaped groove can fit the valve more closely, making the valve more stable when rotating and more convenient for quality inspectors to inspect. BRIEF DESCRIPTION OF THE DRAWINGS
