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 torque motor directly controlled cartridge two-dimensional electro-hydraulic proportional reversal valve. The torque motor directly controlled cartridge two-dimensional electro-hydraulic proportional reversal valve comprises a valve sleeve, a valve core, a corrugated pipe coupler, a rectangular alignment magnetic stripe, a partition plate and a torque motor; a two-dimensional valve and a cartridge valve are combined together, through the characteristic that the two-dimensional valve enables the pilot stage and the power stage to be integrated with two movement freedomdegrees of a single two-dimensional valve core, the design including a two-section valve core and a two-section valve sleeve is adopted, and the cartridge two-dimensional valve is higher in application integration level, power density ratio and pollution resistance compared with a traditional cartridge valve; and the torque is transmitted through the corrugated pipe coupler, alignment resetting is conducted through the alignment magnetic stripe, the complexity of a transmission mechanism of the traditional two-dimensional valve is made up, and the structure is more simple.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of fluid transmission and control, in particular to a plug-in two-dimensional electro-hydraulic proportional reversing valve directly controlled by a torque motor. [0003] 【Background technique】 [0004] 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. [0005] 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 c...
