Description

Technical Field

[0001] The utility model relates to the technical field of valve torque testing, in particular to a torque rotation detection device for valve matching testing. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium (temperature, pressure, and flow). Based on their function, they can be categorized as shutoff valves, check valves, and regulating valves. Valves are control components in fluid conveying systems, performing functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, and overflow pressure relief. Valves used in fluid control systems come in a wide variety of types and specifications, from the simplest shutoff valve to the most complex valves used in automatic control systems.

[0003] Currently, major manufacturers are gradually incorporating destructive inspections of valve opening and closing, as well as twist-off testing, into their designs and production processes. However, most only perform spot checks, making it difficult to prevent defective products from entering the market, which can cause problems for consumers. Furthermore, many rely on manual twist-off inspections, manual inspections, and handwheel rotation, which can be time-consuming, often taking up to three hours to complete a single test. This is labor-intensive and time-consuming, and carries a risk of injury.

[0004] To this end, we have developed a torque rotation detection device for valve coordination testing. Connected via a connecting shaft, it automatically rotates the valve and measures torque in real time. If the movement ends, the torque is detected as excessive and the device automatically stops. Background data can be used to monitor torque changes, allowing for more accurate identification of interference or problems during valve movement. Furthermore, the device utilizes an electric, mobile balancing vehicle, allowing for flexible movement and adjustment, making it suitable for a wide range of applications. This eliminates the need for manual rotation and significantly reduces labor intensity. Utility Model Content

[0022] The preferred embodiment of the torque rotation detection device for valve matching test provided by the utility model is as follows Figure 1-4 A torque rotation detection device for valve coordination testing is shown, comprising an electrically liftable balancing vehicle 11 and a valve torque rotation detection assembly 2. The electrically liftable balancing vehicle 11 includes a balancing vehicle base 111, with a sliding wheel 112 movably mounted on the bottom of the balancing vehicle base 111. A handrail 113 is fixedly mounted on one side of the balancing vehicle base 111, and a baffle 114 is fixedly connected to the outer wall of the handrail 113. A battery device is installed at the bottom of the balancing vehicle base 111, and a hinged seat 115 and a slide plate 116 are fixedly connected to the top of the balancing vehicle base 111. The battery device is used to activate the electric hydraulic lift 12, enabling the balancing vehicle to be raised and lowered, ensuring the accuracy and stability of the valve torque rotation detection assembly 2 during valve testing at different heights. Furthermore, the accurate data transmission of the valve torque rotation detection assembly 2 relies on the stable fixation of the torque sensor 215 and the fixed bracket 216, ensuring the reliability of the test data. Furthermore, the intelligent control of the PLC programmable control screen 213 greatly improves the device's ease of operation and testing efficiency.

[0023] The valve torque rotation detection assembly 2 includes a top plate 211, to which another set of hinged seats 115 and a slide plate 116 are fixedly connected, and an electric hydraulic lifting frame 12 is provided between the two sets of hinged seats 115 and slide plates 116;

[0024] A screen bracket 212 is fixedly mounted on the top of the top plate 211. The top of the screen bracket 212 is movably connected to a PLC programmable control screen machine 213. A three-phase asynchronous motor 214 is also fixedly mounted on the top of the top plate 211. A torque sensor 215 is provided at the output end of the three-phase asynchronous motor 214, and the signal end of the torque sensor 215 is connected to the signal end of the PLC programmable control screen machine 213. A fixed bracket 216 is fixedly connected to the bottom of the torque sensor 215, and the fixed bracket 216 is mounted on the top of the top plate 211. This ingenious design of the valve torque rotation detection assembly 2 not only ensures accuracy during the test process, but also improves the degree of automation of the test, reduces the uncertainty of manual operation, and further optimizes the process and efficiency of valve detection. This design makes the device more stable and reliable in actual application, meeting the needs of various complex working environments.

[0025] When in use, first connect the output end of the three-phase asynchronous motor 214 to the external connecting shaft, and install the torque sensor 215 at the same time, and then connect the connecting shaft to the valve drive to rotate; the valve connecting part is driven by the smooth rotation of the motor to drive the valve movement, and the valve is closed once, so as to find out whether there is assembly interference or incomplete closure when the valve switch is closed; due to the setting of the torque sensor 215, it is possible to detect whether the torque data of the motor rotation is smooth, and transmit the data to the PLC programming control screen machine 213, so as to detect whether there is interference at a certain point when the valve moves. The PLC programming control screen machine 213 controls the setting of the upper and lower limits. When the upper limit torque reaches a certain level, it means that there is interference, so as to more accurately detect problems in the valve closing movement process.
