Description

Technical Field

[0001] This utility model relates to the technical field of valve testing, specifically to a valve remote control torque testing device. Background Technology

[0002] During the factory testing of gate valves, various tests are required, including hydrostatic pressure test of the shell, valve plate and seat sealing test, back seal test, and torque test when opening and closing the valve, to ensure that the valve can be used safely. All of these tests are essential acceptance criteria for valves.

[0003] The torque test of the valve switch during pressure testing is an important acceptance indicator in valve testing. Excessive switching torque makes it difficult to switch the valve under pressure in actual use.

[0004] Each valve has inherent tolerances in its seals, bearings, and manufacturing processes, resulting in varying opening and closing torques for each valve. To ensure optimal performance during operation after shipment, it is crucial to test the opening and closing torque in a laboratory under pressure. Currently, some valve torque tests involve manual entry into the pressure testing chamber, posing safety risks. Furthermore, some instructions only specify the range of torque values ​​for a particular type of valve during performance testing, failing to represent the torque value for each individual valve. This can lead to situations where valves are difficult to operate in the field, creating potential hazards. Therefore, conducting factory torque tests on every valve is imperative. This not only improves testing efficiency but also ensures safety during testing, guaranteeing the reliability of each valve after shipment. Utility Model Content

[0005] The purpose of this invention is to overcome the defects of the existing technology and provide a valve remote control torque testing device.

[0006] This utility model features an overall structural design that utilizes a mechanical universal arm to drive the torque testing device. This allows the operator to easily install the torque testing device onto the test valve, improving installation efficiency. The torque testing device employs a modular design, requiring only one end to be fixed to the mechanical universal arm. Furthermore, it utilizes remote control, directly feeding back to the remote control test bench. Torque testing can be monitored and recorded in real time, significantly improving safety and data reliability compared to manual testing using a torque wrench at close range. Each test requires only the operator to install the connecting joint onto the valve being tested, simplifying the operation. During water pressure and other tests, no additional operations are needed, greatly reducing testing time.

[0007] The objective of this utility model can be achieved through the following technical solutions: A valve remote control torque testing device, comprising: At least one universal robotic arm assembly, the fixed end of which is fixed to a fixed platform or a fixed wall; The universal adjusting arm end of the universal robotic arm assembly is connected to a torque testing device assembly. The torque testing device assembly includes a fixed bracket connected to the universal adjusting arm end of the universal robotic arm assembly, and a torque testing device for measuring the torque when a pressure-tested valve is opened and closed is provided on the fixed bracket. The first signal terminal of the torque testing device is connected to the remote control testing platform; The second signal end of the torque testing device is connected to the valve stem sleeve on the upper part of the pressure-bearing test valve to be measured via a connecting connector. The lower first end of the valve to be tested under pressure is connected to the test flange; The other end of the test flange is connected to the test port of the pressure test control system component.

The operator can easily move the mechanical arm and adjust the connection position over a wide range through mechanical control to better match the valve head.

[0015] 2) The torque testing device components adopt an integrated design, requiring only the provision of connection points for direct installation onto the end effector of the robotic arm. The integration of the motor, reducer, torque sensor, and bracket reduces overall weight, resulting in a compact and safe structure; the entire assembly is protected by an outer casing, enhancing durability.

[0016] 3) The torque testing device adopts remote control equipment components to prevent operators from entering the test site under dangerous pressure conditions, and can record accurate torque values ​​in real time, which not only improves on-site safety requirements, but also makes operation simpler and more convenient.

[0017] 4) The valve remote control torque testing device provided by this utility model adopts a universal joint for the connection joint. When connecting the lower part of the torque testing device to the valve stem sleeve, no precision connection is required. The floating bias makes the installation and connection more convenient and simple.

[0018] 5) The valve remote control torque testing device provided by this utility model features a multi-port bracket on the valve assembly under test, which adopts a multi-individual flow channel design. Multiple brackets can be installed when fixing the valve, saving more operation time during testing.

[0019] 6) The valve remote control torque testing device provided by this utility model has a separate and independent design for the pressure testing device and the torque testing device. This allows for independent pressure testing and torque testing of the valve, greatly improving the reliability of the test. Attached Figure Description
