Abstract
The utility model discloses an electrohydraulic control changing-over valve, which comprises a pilot valve and a valve body, wherein, the valve body comprises a four-function valve body and a sixteen-function valve body which are connected together, communication holes capable of leading into or leading out the liquids in the a liquid inlet, a liquid return port and a work liquid port are provided on the four-function valve body and the sixteen-function valve body, the valve body working liquid port adopts the linear structure to output the working liquid. The utility model adopts two-valve body structure, meanwhile, the liquid outlet vertically outputs the working liquid in the straight-line form, thereby greatly decreasing the volume of the valve body and reducing the weight of the valve body.
Description
Technical field
The utility model relates to a kind of hydraulic support control system, particularly a kind of electric-hydraulic control reversing valve that is applied on the mining hydraulic equipment.
Background technique
Electric-hydraulic control reversing valve is applied to combine the hydraulic support electrohydraulic control system of adopting the automatically working face, be installed on the hydraulic support, it has the function of control multichannel liquid flow path direction, reliable performance, be the critical component in the coal mine hydraulic supporting hydraulic control system, the quality of its performance is directly connected to the stability of whole hydraulic support, reliability and life-span.
In disclosed patent, related to a kind of electric-hydraulic control reversing valve, its main structure is to adopt a valve body, and liquid outlet adopts the vertical output working solution, and the valve volume of this kind structure and weight are all bigger, and cost is also higher.And in fact, descend use, the particularly machine that uses under the coal mine as the ore deposit, excessive weight is inconvenient.This just requires to reduce weight, both can save production cost, and also makes things convenient for the down-hole to install.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of electric-hydraulic control reversing valve, and this electric-hydraulic control reversing valve comprises two valve bodies, and the pilot valve by on the valve body is delivered to spool with hydraulic coupling, realizes commutation function.
The utility model is to adopt following technological scheme to realize:
A kind of electric-hydraulic control reversing valve, comprise pilot valve and valve body, described valve body comprises four function valve bodies and the 16 function valve bodies that link together, be equipped with the ditch through hole that the liquid of liquid entering hole, liquid return hole, working solution mouth can be introduced or drawn on four function valve bodies and the 16 function valve bodies, valve body working solution mouth adopts linear structure output services liquid.
Described four function valve bodies and 16 function valve bodies are by being threaded togather.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
The utility model adopts two valve body structures, and liquid outlet straight line vertical output working solution has reduced valve volume greatly simultaneously, has reduced valve weight.
