Problems solved by technology

However, its function is relatively simple, mainly to realize the on or off of the hydraulic circuit. When used in combination with ordinary hydraulic control valves, it can realize the control of the oil direction, pressure and flow of the system.
Because it needs to be used in combination with other control valves, the hydraulic system is more complicated, and it is not easy to repair when a fault occurs

Abstract

The invention discloses a cover plate cartridge two-dimensional electro-hydraulic proportional reversing valve based on a flexible hinge type compression and twist coupling. The valve is characterizedby comprising valve sleeves, valve elements, a connector, a partition plate, a tubular proportion electromagnet, a compression and twist conversion device and a reset spring; through the adopted segmented valve sleeve and valve element structure, guide and control mechanisms on the two sides of a traditional two-dimensional valve are transferred to the same side, and a single-side stretching rodfull-bridge guide and control mechanism is achieved; and meanwhile, through the design of applying a flexible hinge to the compression and twist conversion device, the cover plate cartridge two-dimensional electro-hydraulic proportional reversing valve has the advantages of being free of friction transmission, good in flexibility, good in dynamic response and small in size.

Description

technical field [0001] The invention relates to the field of fluid transmission and control, in particular to a cover plate plug-in type two-dimensional reversing valve based on a flexible hinge type compression torsion coupling. Background technique [0002] Compared with hydraulic valves with other connection methods, cartridge valves have many irreplaceable advantages such as reliable sealing, light weight, easy system integration, and relatively easy processing and modification. So it is an important development direction of hydraulic technology. [0003] The spool of the cartridge valve has simple structure, sensitive action and good sealing performance. However, its function is relatively simple, mainly to realize the on or off of the hydraulic circuit, and when used in combination with ordinary hydraulic control valves, it can realize the control of the oil direction, pressure and flow of the system. Because it needs to be used in combination with other control valv...
