技术领域technical field
本发明涉及同步阀技术领域，具体涉及了一种混合控制同步阀。The invention relates to the technical field of synchronization valves, in particular to a hybrid control synchronization valve.
背景技术Background technique
同步阀是用来保证两个或两个以上的执行元件(液压缸或液压马达)在承受不同负载时仍能获得相同或成一定比例的流量，从而使执行元件间以相同的位移或相同的速度运动的一种液压元件，同步阀用于是同步提升机构。在同步提升机构使用中，基本运用一个液压阀控制一个执行元件，在提升过程中，因工作阻力的不同，支柱提升不同步，这就造成了速度不同步，影响了运动精度。传统同步阀的典型结构为挂钩式和换向活塞式，国内外专家学者致力于传统同步阀的结构及性能研究多年，但其基本结构沿用至今未发生根本变化。近年，众多学者对同步阀的研究大多局限于80年代学者所建立的理论知识框架里，主要研究内容为两个方面：The synchronizing valve is used to ensure that two or more actuators (hydraulic cylinders or hydraulic motors) can still obtain the same or a certain proportion of flow under different loads, so that the actuators have the same displacement or the same flow. A hydraulic component of speed movement, the synchronizing valve is used to synchronize the lifting mechanism. In the use of the synchronous hoisting mechanism, a hydraulic valve is basically used to control an actuator. During the hoisting process, due to different working resistances, the lifting of the pillars is asynchronous, which causes the speed to be asynchronous and affects the movement accuracy. The typical structures of traditional synchronizing valves are hook type and reversing piston type. Experts and scholars at home and abroad have devoted themselves to the research on the structure and performance of traditional synchronizing valves for many years, but their basic structure has not changed fundamentally so far. In recent years, many scholars' research on synchronous valve is mostly limited to the theoretical knowledge framework established by scholars in the 1980s. The main research contents are two aspects:
(一)影响同步阀稳态和动态性能的因素以及对同步阀结构的改进；(1) Factors affecting the steady-state and dynamic performance of the synchronizing valve and improvements to the structure of the synchronizing valve;
(二)同步阀的应用分析如拖车钻机、框架车。(2) Application analysis of synchronization valve such as trailer drilling rig and frame car.
然而，现代加工技术的发展并未使传统同步阀的性能得到显著改善，这是因为传统同步阀的流量只是近似相等，在原理上存在误差，这一误差不会因为加工精度的提升而无限减小或者消除。However, the development of modern processing technology has not significantly improved the performance of the traditional synchronous valve, because the flow of the traditional synchronous valve is only approximately equal, and there is an error in principle, which will not be infinitely reduced due to the improvement of processing accuracy. small or eliminated.
