Abstract
The utility model discloses an electro-hydraulic proportional flow amplifying valve, and belongs to the field of steering of mechanical engineering technology. The electro-hydraulic proportional flow amplifying valve comprises springs, an electromagnet A, a spring seat, a main valve body, a main valve core and an electromagnet B, the main valve core is arranged inside the main valve body, the springs at the left end and the right end are fixedly arranged at two ends of the main valve core, the springs are fixed by the spring seat, the spring seat is fixed at two ends of the main valve body, and the electromagnet A and the electromagnet B are symmetrically arranged at two ends of the main valve body. The electro-hydraulic proportional flow amplifying valve achieves proportion of displacement of the valve core of the flow amplifying valve and circuit inputting, is not prone to being out of order, capable of improving operational safety, high in controlling accuracy, simple to repair and maintain, easy to disassemble, and simple to operate.
Description
Technical field
The utility model relates to a kind of electric-hydraulic proportion flux amplification valve, belongs to the engineering machinery technology and turns to the field.
Background technique
At present main a kind of form that turns to adopts all-hydraulic steering gear to realize turning to, the flow main slide valve of going here and there after all-hydraulic steering gear carries out flow and amplifies, this main slide valve is flux amplification valve, commutator outputs to pressure oil guide's hydraulic fluid port of flux amplification valve, the throttle orifice that flows through the main valve plug two ends by guide oil causes the main valve plug of pressure reduction control flux amplification valve to move, the big flow of steering pump output enters left and right sides steering cylinder by flux amplification valve, about being finished, loader turns to, but prior art turns to and can cause the turning velocity of steering wheel rotating speed and processing to be non-linear relation, easy to failure, operating security is low, and control accuracy is low, technical sophistication and maintenance difficult.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of electric-hydraulic proportion flux amplification valve, can make the spool travel of flux amplification valve and input current proportional, not easy to failure, operating security improves, the control accuracy height, maintenance is simple, and is quick detachable, simple to operate.
To achieve these goals, the utility model is achieved through the following technical solutions: a kind of electric-hydraulic proportion flux amplification valve, comprise spring, electromagnet A, spring seat, main valve body, main valve plug and electromagnet B, main valve plug is installed in the main valve body, the spring at two ends, the left and right sides is fixedly mounted on the main valve plug two ends, spring is fixed with spring seat, and spring seat is fixed on the two ends of main valve body, and electromagnet A and the electromagnet B of symmetry is installed at the two ends of main valve body simultaneously.
The beneficial effects of the utility model are: make the spool travel of flux amplification valve and input current proportional, actuator port can pro rata output flow, and is not easy to failure, and operating security improves, the control accuracy height, and maintenance is simple, and is quick detachable, simple to operate.
Description of drawings
Fig. 1 is agent structure schematic representation of the present utility model.
Among the figure: 1, spring, 2, electromagnet A, 3, spring seat, 4, main valve body, 5, main valve plug, 6, electromagnet B.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of electric-hydraulic proportion flux amplification valve, comprise spring 1, electromagnet A2, spring seat 3, main valve body 4, main valve plug 5 and electromagnet B6, main valve plug 5 is installed in the main valve body 4, the spring 1 at two ends, the left and right sides is fixedly mounted on main valve plug 5 two ends, spring 1 usefulness spring seat 3 is fixing, and spring seat 3 is fixed on the two ends of main valve body 4, and electromagnet A2 and the electromagnet B6 of symmetry is installed at the two ends of main valve body 5 simultaneously.When input current not, flux amplification valve main valve plug 5 is in meta, the hydraulic oil in P chamber does not communicate with the hydraulic oil of left and right sides active chamber A, B, when at electromagnet A2 input current, forms magnetic circuit behind the coil electricity, it is proportional to produce suction and input current, be the ouput force of proportion electro-magnet, under the effect of spring 1, main valve plug 5 produces and the proportional displacement of electric current, signal is controlled the displacement of main valve plug 4 continuously pari passu, and hydraulic oil and the active chamber A in control P chamber are interconnected; Together should be when B electromagnet 6 input currents, the hydraulic oil in P chamber and active chamber B are interconnected.
