Description
Technical field
The utility model relates to a kind of electro-hydraulic reversing valve, especially relate to a kind of can with the electro-hydraulic reversing valve of the direct cross complaint in the external world.
Background technique
Electro-hydraulic reversing valve is the combination of solenoid directional control valve and pilot operated directional control valve, and it is the control valve of the action controlling pilot operated directional control valve with solenoid directional control valve, conversion fluid flow direction.Electro-hydraulic reversing valve is mainly used in and flows exceed solenoid directional control valve and normally work in the hydraulic system of allowed band, controls, or control the flow direction of fluid the action of executive component.
In existing electro-hydraulic reversing valve, first control hydraulic fluid port of pilot operated directional control valve is directly communicated with solenoid directional control valve hydraulic fluid port through left end cap by oil line pipe, and the second control hydraulic fluid port of pilot operated directional control valve is directly communicated with through another hydraulic fluid port of right end cap and solenoid directional control valve by oil line pipe.The main valve plug that wherein solenoid directional control valve controls pilot operated directional control valve as pilot reversing valve slides, now, the main valve plug of pilot operated directional control valve can only be controlled by the pilot reversing valve of self, extraneous oil hydraulic circuit or hydrovalve directly can not control pilot operated directional control valve, the pilot reversing valve of pilot operated directional control valve directly can not control extraneous oil hydraulic circuit or hydrovalve, therefore can not realize the function of the direct cross complaint with the external world.
But electro-hydraulic reversing valve is in commercial Application, often need to realize can with the function of extraneous oil hydraulic circuit or the direct cross complaint of hydrovalve.For realizing this function, people generally adopt and install transition block between solenoid directional control valve and pilot operated directional control valves, and in transition block, process many external control runners, wherein an external control runner makes solenoid directional control valve be communicated with extraneous oil hydraulic circuit or hydrovalve, and wherein another external control runner makes pilot operated directional control valve be communicated with extraneous oil hydraulic circuit or hydrovalve.This kind of structure need process transition block separately, and complex structure, cost are higher and use is inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, cost is lower and easy to use can with the electro-hydraulic reversing valve of the direct cross complaint in the external world.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of can with the electro-hydraulic reversing valve of the direct cross complaint in the external world, comprise solenoid directional control valve and pilot operated directional control valve, described pilot operated directional control valve two ends have end cap, the first external control runner and the second external control runner is provided with in end cap described in one of them, the first described external control runner and the second described external control runner are through described end cap, the first described external control runner Single port Q3 is communicated with described solenoid directional control valve hydraulic fluid port A2, the first described external control runner another port Q1 can be communicated with extraneous oil hydraulic circuit or hydrovalve, the second described external control runner Single port Q4 is controlled hydraulic fluid port K1 with first of described pilot operated directional control valve and is communicated with, the second described external control runner another port Q2 can be communicated with extraneous oil hydraulic circuit or hydrovalve.
The first described external control runner comprises the first branch flow passage and the second branch flow passage, the first described branch flow passage is perpendicular to the second described branch flow passage and intersect at the first hydraulic fluid port R1, the first described branch flow passage and the second described external control runner are laterally set in parallel on described end cap, the extension of the second described branch flow passage is perpendicular to the second described external control runner and intersect at the second hydraulic fluid port R2, is provided with dismantled and assembled plug between the first described hydraulic fluid port R1 and the second described hydraulic fluid port R2.When detachable plug blocks the extension of the second branch flow passage, and when port Q1 with Q2 is communicated with extraneous hydraulic circuit or hydrovalve, electro-hydraulic reversing valve can with extraneous hydraulic circuit or the direct cross complaint of hydrovalve; When detachable plug does not block the extension of the second branch flow passage, and when port Q1 with Q2 is not communicated with extraneous hydraulic circuit or hydrovalve, the pilot operated directional control valve of electro-hydraulic reversing valve is controlled by solenoid directional control valve.
The oil inlet P 1 of described pilot operated directional control valve is communicated with the oil inlet P 2 of described solenoid directional control valve, the oil outlet T1 of described pilot operated directional control valve is communicated with the oil outlet T2 of described solenoid directional control valve, and the second control hydraulic fluid port K2 of described pilot operated directional control valve is communicated with described solenoid directional control valve.Solenoid directional control valve oil circuit is communicated with pilot operated directional control valve oil circuit.
Compared with prior art, the utility model has the advantage of and the first external control runner and the second external control runner are set in an end cap wherein, first external control runner Single port Q3 is communicated with solenoid directional control valve hydraulic fluid port A2, first external control runner another port Q1 can be communicated with extraneous oil hydraulic circuit or hydrovalve, second external control runner Single port Q4 is connected with pilot operated directional control valve K1, second external control runner another port Q2 can be communicated with extraneous oil hydraulic circuit or hydrovalve, thus realize phase electro-hydraulic reversing valve and extraneous oil hydraulic circuit or the direct cross complaint of hydrovalve, compared with the electro-hydraulic reversing valve in traditional installation transition iron block, the utility model omits transition iron block, structure is simple, without the need to additional processing transition iron block, reduce costs, and this electro-hydraulic reversing valve can directly be installed, practical and convenient.
