Description
Technical field
The present invention relates to a kind of electromagnetic hydraulic valve, especially relate to a kind of manual and electric dual-purpose electromagnetic hydraulic valve.
Background technique
Used hydrovalve mainly contains electronic and manual two kinds at present, and mortor operated valve obtains using more widely owing to it is applicable to automatic control oil channel.But simple mortor operated valve (being solenoid valve) exists the problem of function singleness, operation underaction, often is difficult to realize when needs manually carry out auxiliary operation.In order to realize the manual and electric dual-purpose of electromagnetic hydraulic valve, people have proposed many design proposals, and are put to implement.Application number is that 200610154752.9 patent of invention discloses a kind of bi service electromagnetic valve, has valve body, by valve pocket, inlet passage and the outlet passage that valve body surrounded, be arranged on valve seat, spool, spring, moving iron core, winding, fixed core in the valve pocket, and push rod; Described valve pocket, inlet passage and outlet passage communicate, and described spring is between described spool and described fixed core and be set on the described push rod, and described winding is around described fixed core setting; It is characterized in that: an end of described push rod stretches out valve pocket and exposes outside the valve pocket, and the other end of described push rod stretches in the valve pocket and with described moving iron core fixedlys connected.This technological scheme can adopt manual unblank and rely on electromagnetic attraction to keep normal open state, also can adopt the electromagnetism unblank and relies on electromagnetic attraction and keep normal open state, and need not before electronic unblank path to be verified.Application number is that 98250200.1 model utility discloses a kind of hand, electric bi service electromagnetic valve, it mainly is made up of valve body, valve pocket, electromagnetic valve core, manual spool, liquid entering hole and liquid outlet, in valve pocket, be provided with two paths, manually spool is located between two paths, manually having pilot hole on the spool, on off operating mode by the manual two paths of pilot hole comes the path of controlling liquid by passage, to realize hand, the dual-purpose purpose of electricity, the hand of Huo Deing, electric bi service electromagnetic valve therefrom.But technique scheme only is applicable to that generally some hydraulic fluid flow rates are big, precision is not high, the bigger hydrovalve in the interior space of valve.Less between height in, the valve high especially for required precision, more especially be used for the hydrovalve of high-voltage electrical apparatus switch, just need to adopt more rational controlling method and structural configuration.
Summary of the invention
The present invention solves that the existing in prior technology precision is not high, valve volume big, switches technical problems such as there being trouble between the manual and electric, provide a kind of simple in structure, flexible operation, precision height, valve volume little, can be applicable to the manual and electric dual-purpose electromagnetic hydraulic valve of high-precision high-voltage electrical apparatus control switch.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of manual and electric dual-purpose electromagnetic hydraulic valve, comprise valve body, spool, valve gap and Electromagnetic Control mechanism, it is characterized in that there is an electromagnetic coil in described Electromagnetic Control mechanism, the left end of electromagnetic coil is provided with a static iron core, static iron core is provided with a through hole that communicates up and down, this through hole is connected with the endoporus of described electromagnetic coil, the endoporus of electromagnetic coil is provided with a moving iron core, described through hole is passed in the upper end of moving iron core, contact with the shifting lever of a spool, the upper end of moving iron core is provided with a manual rod.When the interim hand control valve body of needs opens and closes, can promote movable valve plug by manual rod downwards and move downward, and then promote shifting lever, by shifting lever control valve core movement, open hydrovalve; When employing was automatically controlled, as long as to the electromagnetic coil energising, static iron core drove moving iron core and moves downward under magnetic force, and then promotes shifting lever, controls valve core movement by shifting lever, opens hydrovalve.Stir valve core movement by having adopted shifting lever here, dwindle on the one hand because of the influence of the kinematic error of moving iron core, have laborsaving effect owing to lever on the other hand, so can reduce the number of turn of electromagnetic coil to the valve core movement stroke, thereby reduce the volume of device, make its structure more compact.
As preferably, described shifting lever is made of cross bar and vertical pole, and vertical pole is located at the left side of valve body, and contacts in the spool left end, and the lower end of vertical pole is the rotating fulcrum of shifting lever; Cross bar is located at the upside of valve body, and contacts with moving iron core lower end.At an angle, and be in the left side and the upside of valve body respectively between vertical pole and the cross bar, make its structure more compact, volume is littler, also is convenient to install.
As preferably, described spool from left to right is made of the push rod of being located at valve opening, steel ball, pressure spring and blind nut, be respectively equipped with oil outlet and oil inlet hole on the valve body of the left and right sides of described steel ball, be provided with filter screen between spool and the oil outlet, described push rod left end contacts with the vertical pole of turning lever, and blind nut matches with the valve opening right-hand member.Push rod can move right under the effect of shifting lever, and promote steel ball and move right, steel ball from originally and the tight state of contact of sealing edge in the valve opening backed down, realize that left and right sides oil circuit communicates, the hydraulic oil that enters valve body from filler opening need pass through filter screen, and it is filtered.When the effect disappearance of turning lever, steel ball moves right under the effect of pressure spring and high-pressure and hydraulic oil, the blocking-up oil circuit.
As preferably, the outside of described electromagnetic coil is provided with a solenoid housing, and the outside of this solenoid housing evenly is provided with radiating fin.Housing has protective action to coil, and radiating fin can improve the radiating efficiency of electromagnetic coil, improves its working life.
As preferably, the upside of described solenoid housing is provided with a tail-hood, and the upside of tail-hood is provided with an elastic button, and elastic button contacts with manual rod.The setting of tail-hood and elastic button can have protective action to it so that coil, moving iron core, manual rod can not expose, and its profile is also more attractive in appearance simultaneously.
As preferably, described turning lever is located in the cavity of valve gap.This set makes that its structure is more compact, it is safer to use, and its structure is had protective function.
As preferably, the vertical pole of described turning lever and the point of contact of push rod are resistance point A, and the point of contact of cross bar and moving iron core is power point B, if the hypothesis rotating fulcrum is O, then OB be OA 3-6 doubly.OB is 3-6 a times of OA, can make in enhancing productivity, saving production cost so that the kinematic error of moving iron core be narrowed down to 1/6 to 1/3 by lever.
As preferably, the line of described electromagnetic coil directly is between the 0.135-0.145, and its number of turn is between the 3500-4000.
The beneficial effect that brings of the present invention is, solve that the smart Gao Bugao of hole existing in prior technology, valve volume are big, switch the technical problem that has trouble etc. between the manual and electric, simple in structure, flexible operation, precision height, the valve volume of having realized manual and electric dual-purpose electromagnetic hydraulic valve are little, can be applicable to high-precision high-voltage electrical apparatus control switch.Particularly be applicable to the high-pressure and hydraulic control switch of 60 MPa levels.
