Abstract
The invention relates to an ultra-thin type electro-hydraulic reversing valve which comprises a valve body (1) and an electromagnetic pilot valve (2). The electromagnetic pilot valve (2) is arranged on the valve body (1). The valve body (1) is provided with a valve element (3), a one-way valve (4), a filter (5), a wire outlet hole (6), a liquid inlet through hole P and a liquid returning through hole O. The single-layer valve element (3) is arranged in the valve body (1), the one-way valve (4) is arranged on the valve body (1), the one-way valve (4) is communicated with the liquid returning through hole O, the filter (5) is arranged on the valve body (1), the filter (5) is communicated with the liquid inlet through hole P, and the wire outlet hole (6) is arranged at the back of the electromagnetic pilot valve (2). The ultra-thin type electro-hydraulic reversing valve is small in size, small in occupied space, simple in structure and convenient to install in a pit.
Description
Technical field
The invention belongs to the electric-hydraulic control reversing valve field, be specifically related to a kind of ultrathin electric-hydraulic control reversing valve.
Background technique
The coal fully-mechanized mining is the important symbol of coal mining technical modernization.Along with the continuous development of science and technology, the traditional electrical pilot operated directional control valve is owing to exist complex structure, inconvenient maintenance, and sealing is poor, and volume causes greatly taking up room greatly, and Heavy Weight is in deficiencies such as down-hole installation inconvenience.
In the prior art, electrohydraulic controlled reversal valve in use for hydraulic support by electromagnetic priority valve, main valve body and spool form, but pilot valve adopts vertical installation, the main control valve aspect ratio is higher, the two-layer arrangement up and down of spool in the main control valve causes the electric-hydraulic control reversing valve volume big, and it is big to take up room, complex structure, inconvenience is installed in the down-hole.
Summary of the invention
Technical problem to be solved by this invention overcomes the prior art deficiency exactly, provides a kind of volume little, compact structure, is convenient to the ultrathin electric-hydraulic control reversing valve that install the down-hole.
Technological scheme of the present invention: a kind of ultrathin electric-hydraulic control reversing valve, it comprises valve body 1, electromagnetic priority valve 2, electromagnetic priority valve 2 is arranged on the valve body 1, valve body 1 is provided with spool 3, one-way valve 4, filter 5, wire outlet hole 6, feed liquor through hole P and returns fluid through-hole O, it is characterized in that being provided with in the valve body 1 individual layer spool 3, one-way valve 4 is arranged on the valve body 1, one-way valve 4 is communicated with time fluid through-hole O, filter 5 is arranged on the valve body 1, filter 5 is communicated with feed liquor through hole P, and described wire outlet hole 6 is arranged on electromagnetic priority valve 2 back.
Beneficial effect of the present invention: 1. the present invention adopts horizontal mounting type, reduces the height of electric-hydraulic control reversing valve on can be largely, has saved installing space; 2. cable group of the present invention adopts rear leading-out mode, can directly be connected with controller or be connected with electromagnetic driver, and volume is little, and is simple in structure, is convenient to the down-hole and installs; 3. the present invention is built in filter and unmarried valve in the main valve body, makes valve body realize compact structure under the prerequisite of its various functional requirements.
