Background technique
Synchronous valve is for ensuring that two or more executive components (hydraulic cylinder or hydraulic motor) are bearing difference
It remains to obtain identical or proportional flow when load, thus with identical displacement or identical speed between making executive component
A kind of Hydraulic Elements of movement, synchronous valve then synchronous lifting mechanism.In synchronous lifting mechanism in use, basicusing one
Hydraulic valve controls an executive component, and in lifting process, because of the difference of working resistance, pillar promotion is asynchronous, this is resulted in
Speed is asynchronous, affects kinematic accuracy.The typical structure of conventional synchronization valve be coupling type and reversing piston formula, both at home and abroad specially
Family scholar is dedicated to structure and the performance study many years of conventional synchronization valve, but its basic structure is used till today and do not occur to become at all
Change.In recent years, numerous scholars are confined in the theoretical knowledge frame that the eighties, scholar was established the research of synchronous valve mostly, mainly
Research contents is two aspects:
(1) improvement of the synchronous valve stable state with the factor of dynamic property and to synchronous valve arrangement is influenced；
(2) applied analysis of synchronous valve such as drilling machine for trailer, chassis.
However, the development of modern processing does not make the performance of conventional synchronization valve significantly improve, this is because passing
System synchronous valve flow be it is approximately equal, there is error in principle, this error will not because of machining accuracy promotion and
It is unlimited to reduce or eliminate.
Summary of the invention
Present invention aims to overcome that the shortcomings that prior art and deficiency, provide a kind of dual spool control synchronous valve,
