Description
Technical Field
The invention relates to a rotary high-speed switch valve with adjustable through-flow capacity and a control method thereof, relating to the technical field of digital hydraulic elements.
Background
With the development of the times, computers are widely applied to various fields, which leads to the trend of digitalization of more and more products for interacting with computers, as in the hydraulic field, thus promoting the generation of a batch of digital hydraulic components, of which high-speed switching valves are one. Compared with the traditional servo valve and the traditional proportional valve, the high-speed switch valve has many advantages, has stronger pollution resistance, reliability and repeatability, is easy to maintain, has high cost performance and has wide development prospect.
The existing high-speed switch valve is basically a direct-acting high-speed switch valve, the high-speed switch valve generates electromagnetic force to push a valve core to move by electrifying a coil, and the valve core is reset by hydraulic pressure or spring force, and the valve core can collide with a valve seat in the movement or resetting process, so that in the working process, the direct-acting high-speed switch valve can generate larger vibration and noise, and the service life of the valve is shortened. For a direct-acting high-speed switch valve of a specific model, the maximum oil flow rate is fixed, when the work needs larger oil flow rate, the original direct-acting high-speed switch valve is difficult to provide the flow rate required by the work, so the direct-acting high-speed switch valve is usually used as a pilot valve in engineering application, or a valve group array mode is adopted, namely, a plurality of high-speed switch valves are used simultaneously to realize larger oil flow rate, and in the valve group array, the high-speed switch valves are required to have different maximum oil flow rates so as to realize better control effect.
The existing design of the direct-acting high-speed switch valve still has the following defects, which are mainly expressed as follows:
1. the existing direct-acting high-speed switch valve is electrified through a coil to generate electromagnetic force, a valve core is pushed to move to open a valve port, and the valve core is pushed to reset through hydraulic pressure or spring force to close the valve port. However, when the valve port is opened or closed, the valve core and the valve seat collide with each other, which affects the service life of the valve. Aiming at the negative effects caused by collision impact, the conventional direct-acting high-speed switch valve adopts a measure of reducing the mass of a valve core, and reduces the inertia force of the valve core in the process of quick opening and closing by reducing the mass of the valve core, thereby achieving the effect of reducing the impact. However, vibration noise generated by collision of the valve core and the valve seat is still unavoidable, and applicability of the valve under extreme working conditions is limited.
2. The maximum oil flow of the existing direct-acting high-speed switch valve during working is determined by the flow area of a valve port, in order to meet the requirement of larger flow in engineering application, a plurality of scholars propose an array type high-speed switch valve group, namely a plurality of high-speed switch valves are adopted for control at the same time, the adopted high-speed switch valves have two choices, one is that the high-speed switch valves with the same type and the same flow capacity are adopted, the high-speed switch valves have the same control characteristics and are simpler to control, but the flow combination is less because the flow rates are the same; the other type of high-speed switch valve with different flow capacities is adopted, so that the high-speed switch valve has different flow capacities, the generated flow combinations are more, and more flow combinations mean that the control system has better control precision, but the high-speed switch valves of different types have different control characteristics, so that the control becomes more complicated.
