Problems solved by technology

In the overall process, there are limitations and complexities such as repeated pressurization of cold air, long cycle, high cost and other conditions, which slow down the debugging and improvement process of the control system, prolong the development cycle of the valve device, and cannot realize the rapid development of the valve device to meet actual needs. application
[0004] It can be seen that the debugging process of the existing conventional valve device needs to go through the no-load environment and the air-conditioning environment, and finally apply it in the actual environment, the process cycle is long and the cost is high

Description

technical field [0001] The invention relates to the technical field of simulated load devices, in particular to a large-scale adjustable simulated load device. Background technique [0002] As the core part of the power system, the engine needs to have the characteristics of reliable operation, fast response, and high control precision. The valve device is widely used in the actuator of the engine because of its light and small size, fast response, and high reliability. [0003] In practical applications, the control system of the valve device is particularly critical, and its control characteristics determine whether the gas valve device can be accurately executed according to the set timing. The conventional control and debugging process of the current valve device is carried out in the order of no-load environment-air-conditioning environment-actual environment, and the control system is continuously adjusted or improved in the process until it meets the actual needs, so ...
