Abstract
The utility model discloses an electro-hydraulic control valve which comprises a valve body. A valve cover is fixedly arranged on the valve body; a transverse energy storage valve cavity 1, an energy storage valve cavity 2 and a constant-pressure valve cavity are arranged in the valve body; an energy storage valve core 1, an energy storage valve core 2 and a constant-pressure valve core are respectively arranged in the energy storage valve cavity 1, the energy storage valve cavity 2 and the constant-pressure valve cavity; an oil inlet channel which is arranged in the valve body is respectively communicated with oil inlets of the energy storage valve cavity 1, the energy storage valve cavity 2 and the constant-pressure valve cavity; an electromagnetic change valve is arranged on the valve cover, and an oil inlet of the electromagnetic change valve is communicated with an oil outlet of the constant-pressure valve cavity by an oil channel. With simple structure and convenient as well as easy operation, the electro-hydraulic control valve can easily adjust the flowing of pressure oil.
Description
Technical field:
The utility model relates generally to a kind of valve body, relates in particular to a kind of electro-hydraulic control valve.
Background technique:
In hydraulic system, mainly form by parts such as valve body, spool, valve gap and springs as the hydrovalve of control unit.Analyze from principle, this control unit mainly is to satisfy the control requirement by the dependence matching gap between the two that the relative movement between valve body and the spool realizes to the control of oil liquid pressure, flow and direction.Therefore, the under high pressure necessary relative movement neatly of valve body and spool, and want to reduce internal leakage.At present, also do not utilize solenoid directional control valve to come the electro-hydraulic control valve of pilot pressure oil trend on the market.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of simple in structure, easy to operate electro-hydraulic control valve to be provided.
The utility model is achieved through the following technical solutions:
A kind of electro-hydraulic control valve, include valve body, be installed with valve gap on the described valve body, be provided with horizontal energy storage valve pocket one in the described valve body, energy storage valve pocket two and level pressure valve pocket, described energy storage valve pocket one, be separately installed with energy storage spool one in energy storage valve pocket two and the level pressure valve pocket, energy storage spool two and level pressure spool, be provided with oil inlet passage in the described valve body, described oil inlet passage respectively with energy storage valve pocket one, the filler opening of energy storage valve pocket two and level pressure valve pocket is connected, it is characterized in that: on the described valve gap solenoid directional control valve is installed, the filler opening of described solenoid directional control valve is connected by the oil outlet of oil circuit with the level pressure valve pocket.
The utility model is by the trend that solenoid directional control valve comes switch pressure oil, the purpose that obtains commutating, and the electrical equipment reversing bar that operator only need stir on the solenoid directional control valve is promptly capable of reversing, operates lighter.
The utility model has the advantages that:
The utility model is simple in structure, and is easy to operate, light, the trend of energy easy adjustment pressure oil.
Description of drawings:
Fig. 1 is a plan view of the present utility model.
Fig. 2 be A to sectional view.
Embodiment:
A kind of electro-hydraulic control valve, include valve body 1, be installed with valve gap 2 on the described valve body 1, be provided with horizontal energy storage valve pocket one in the described valve body 1, energy storage valve pocket two and level pressure valve pocket, described energy storage valve pocket one, be separately installed with energy storage spool 1 in energy storage valve pocket two and the level pressure valve pocket, energy storage spool 25 and level pressure spool 6, be provided with oil inlet passage in the described valve body 1, described oil inlet passage respectively with energy storage valve pocket one, the filler opening of energy storage valve pocket two and level pressure valve pocket is connected, solenoid directional control valve 3 is installed on the valve gap 2, and the filler opening of described solenoid directional control valve 3 is connected by the oil outlet of oil circuit with the level pressure valve pocket.
