[0045] As a specific implementation of the present invention, please refer to Figures 1 to 5 The support ear 2 is provided with an oil port connected to the oil port of the test valve component 7.

[0046] The device uses welding technology to weld the fixed bracket 6, the oil cylinder and the base 5 to the bottom plate 1 to form an integrated platform. The base 5 is mounted with the support lug 2, the bearing and the transmission shaft. The angle encoder 31 is fixed on the end face of one side of the rotating shaft. The device mounts the rotary throttle valve on the fixed bracket 6, and the oil inlet of the rotary throttle valve is connected and fixed on the support lug 2; the extension and contraction movement of the oil cylinder drives the support lug 2 to swing, thereby driving the oil inlet of the rotary throttle valve to rotate, so as to adjust the valve port size, thereby adjusting the flow rate, and then controlling the movement speed of the actuator. The oil outlet of the rotary throttle valve is connected to the oil port on the side of the support lug 2, and the throttle valve housing is clamped and fixed by the fixed bracket 6. The oil flow is realized by connecting the oil port on the support lug 2 with the oil port of the valve under test.

[0047] The utility model also provides a rotary throttle valve test method, comprising the following steps:

This type of rotary throttle valve test equipment also has a wide range of adaptability. It can adapt to the test of throttle valves of the same principle and different specifications. It only needs to modify the oil port size on the lug to be suitable for the installation of the throttle valve. The angle measurement accuracy is high. For a rotary throttle valve, the rotation angle during operation is very critical. The traditional angle sensor has a large measurement error due to the lack of a good measurement benchmark. By installing an angle encoder at the end of the shaft, the rotation of the throttle valve core is transmitted to the input shaft of the angle encoder to achieve 1:1 transmission with an accuracy of 0.1 degrees. The test swing angle range is large. The test platform is mainly composed of a base plate 1, a fixed bracket 6 and a base 5, which are used for the installation and fixation of the rotary throttle valve, and the fixation and positioning of one end of the tooling oil cylinder. The stroke of the driving oil cylinder is 400mm, the cylinder diameter is 40mm, and it can provide a thrust of more than 100kg to meet the large swing angle rotation of the throttle valve and the connecting lug. It is easy to realize automatic control. The lug 2 connecting the oil cylinder and the throttle valve is connected to the rotary shaft installed on the base 5 through a bearing, and rotates relative to the base 5. The angle encoder 31 is coaxial and corotates with the connecting shaft to realize real-time detection of the angle information and stop supplying oil after the oil source system reaches the required angle through program feedback. It is suitable for testing valve parts under the condition of 0-1600L / min, and has a large flow range. The oil outlet of the rotary throttle valve and the return oil pipeline of the oil source system are connected through the lug 2 respectively, and a large diameter oil circuit can be made to meet the large flow test requirements of the valve parts. The angle control accuracy is high. The support ear is rotated by extending and retracting the oil cylinder, and the support ear 2 drives the angle encoder 31 to rotate. The display instrument reads the encoder signal, and the control rotation angle accuracy can reach 0.1°.
