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

Abstract

The invention discloses a large-range adjustable analog load device which comprises a load rack, an automatic loading device, a mechanical transmission device and a limiting device. The automatic loading device, the mechanical transmission device and the limiting device are installed and fixed through the load rack. The automatic loading device is arranged in the load rack; the mechanical transmission device is arranged at the horizontal central axis of the load rack and runs through the load rack and the automatic loading device; and a limiting device is arranged on the mechanical transmission device so as to limit the movement path of the mechanical transmission device. The wide-range adjustable analog load device has the characteristics of wide-range adjustability, quick response, automatic loading and the like.

Description

Technical field [0001] The invention relates to the technical field of analog load devices, in particular to a large-range adjustable analog load device. Background technique [0002] As the core part of the power system, the engine needs to have the characteristics of reliable work, fast response, high control accuracy, etc., and the valve device is widely used in the actuator of the engine due to its light and small size, fast response, and high reliability. [0003] In practical applications, the control system of the valve device is particularly critical. The quality of its control characteristics determines whether the gas valve device can accurately execute according to the set time sequence. The current routine control and debugging process of the valve device follows the sequence of no-load environment-air-conditioning environment-actual environment. During the process, the control system is continuously adjusted or improved until it meets the actual needs, so that the valv...
