Description
Technical field
The utility model belongs to mine hydraulic bracket Hydraulic Elements, is specifically related to a kind of electromagnetic force strong, the mining intrinsic safety electro magnetic pilot valve of structure durable.
Background technology
At present, conventional mining electromagnetic priority valve, because electromagnetic coil is pounded number less, electromagnetic force is little, causes the suction-combining force of upper armature and lower armature little, also just causes the pressure on top surface of the push rod in electromagnetic valve little, causes spool to open; Also have original push rod diameter little, in the time being subject to impact force, easily make push rod distortion fracture, bring great inconvenience to coal production.
Summary of the invention
The utility model is exactly in order to solve existing FHD1.6/31.5X type mining intrinsic safety electro magnetic pilot valve because electromagnetic coil is pounded number less, the problem of electromagnetism push rod frangibility, and a kind of mining intrinsic safety electro magnetic pilot valve has been proposed.The utility model is simple in structure, and cost is low, and only need on the basis of original structure, carry out very little change just can solve a great problem on colliery.
The technical solution adopted in the utility model: a kind of mining intrinsic safety electro magnetic pilot valve, it comprises junction box 1, electromagnetic valve 2, pilot valve 3, junction box 1 is fixedly connected on the left side of electromagnetic valve 2, electromagnetic valve 2 is fixedly connected on pilot valve 3, electromagnetic valve 2 is made up of two groups of electromagnetism pusher structures of symmetrical configuration, comprise electromagnetic valve housing 4, upper cover component 5, push rod 6, coil brace 7, electromagnetic coil 8, upper armature 9 and lower armature 10, wherein in electromagnetic valve housing 4, be provided with a circle electromagnetic coil 8, electromagnetic coil 8 is fixed by coil brace 7 supportings, wire in junction box 1 and electromagnetic coil 8 are connected, coil brace 7 inner rings in electromagnetic valve housing 4 are provided with upper armature 9 and lower armature 10, push rod 6 is through upper armature 9 and lower armature 10 center, and stretch out a lower armature part, wherein upper armature 9 drives push rod 6 to move up and down with respect to lower armature 10, upper cover component 5 lids are located at electromagnetic valve housing 4 upper ends, pilot valve 3 is made up of two groups of spool control members of symmetrical configuration, comprise guide valve blocks 11, depression bar 12, core assembly 13 and screw plug 14, depression bar 12 is connected with guide valve blocks 11 by bearing pin, core assembly 13 is inserted in guide valve blocks 11, by screw plug 14 shutoff, wherein depression bar 12 utilizes lever principle to carry out the open and close of the interior inlet of control valve core assembly 13 and liquid return hole in the bottom surface, one end that is connected with bearing pin under the promotion of push rod 6.
The utility model compared with prior art its beneficial effect is: the utility model mining intrinsic safety electro magnetic pilot valve only needs less electric current to produce can promote the required thrust of core assembly in pilot valve mechanism, thereby reduce operation energy consumption, and then reduced cost of production and use cost; Push rod and the depression bar opened due to the utility model control spool are interactive layouts, have utilized dexterously lever principle, only need will be very little motive force, just can make spool unlatching, reduced the load of electromagnetic coil and push rod.
