The model utility content
Technical problem to be solved in the utility model provides a kind of wet type solenoid directional control valve, and it by changing body runner mode, improves performance under the prerequisite that does not increase original cost, satisfy the demand of pressurized oil system.
For solveing the technical problem, the utility model provides a kind of wet type solenoid directional control valve, it is characterized in that, the wet type solenoid directional control valve comprises body, spool, washer, Returnning spring, an O type circle, electric screwed pipe, coil, the 2nd O type circle, plastic cap nut, spool is located in the body, washer, Returnning spring are enclosed within on the spool successively, the one O type circle is located between body and the electric screwed pipe, electric screwed pipe be locked at body above, coil is enclosed within the top of electric screwed pipe and fastening by plastic cap nut and electric screwed pipe; The 2nd O type circle is located between plastic cap nut and the coil.
Preferably, the length of described body is 97.6mm.
Preferably, described wet type solenoid directional control valve also comprises nameplate, plug, plug be inserted in coil above, nameplate be locked at body above.
Positive progressive effect of the present utility model is: when the utility model needs to use high flow, pressure and superperformance in pressurized oil system, under the prerequisite that does not increase original cost, by changing body runner mode, improve performance, satisfy the demand of pressurized oil system.
Description of drawings
Fig. 1 is the utility model one embodiment's a structural representation.
Embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model wet type solenoid directional control valve comprises body 1, spool 2, washer 3, Returnning spring 4, an O type circle 5, electric screwed pipe 6, coil 7, the 2nd O type circle 8, plastic cap nut 9, nameplate 10, plug 11, spool 2 is located in the body 1, washer 3, Returnning spring 4 are enclosed within on the spool 2 successively, the one O type circle 5 is located between body 1 and the electric screwed pipe 6, electric screwed pipe 6 be locked at body 1 above, coil 7 is enclosed within the top of electric screwed pipe 6 and fastening by plastic cap nut 9 and electric screwed pipe 6.The 2nd O type circle 8 is located between plastic cap nut 9 and the coil 7, is used for the water-stop effect.Plug 11 be inserted in coil 7 above, nameplate 10 be locked at body 1 above.The length of body 1 is 97.6mm.Washer 3 is pads that four through holes arranged and step is arranged, and the shape of washer 3 is circular.
Wherein, main body structure is five slot type symplex structures, body is a cuboid cast iron workpiece that the runner design is arranged, it has four runners and seven oil circuit chambeies, first flow P, the second runner T, the 3rd runner A, the 4th runner B runner and the first chamber X, the second chamber Y, first flow P is the pressure oil inlet, and the second runner T connects fuel tank.Spool is an elongated cylinder that adopts special high-quality import steel (as the SCM415 type) processing, spool is installed in the matching hole of body, spool can be free to slide in body, at the diverse location of spool, can cooperate body to realize different oil circuit on-off functions by design to the spool different structure.Washer is a kind of pad through special thermal treatment, and main body is used for the supporting effect of Returnning spring and spool, and middle four through holes are used for the vacuum adsorption force that logical oil prevents that spool handoff procedure and body from producing.Returnning spring is the precision machining part that a kind of end face polishes, and is used for when the electromagnet no electric circuit, guarantees the neutral position of spool.The material of the one O type circle adopts nitrile rubber, is used for the oil pressure seal action of body and electric screwed pipe.Electric screwed pipe is a kind of processing assembly parts, when coil electricity, the push rod in the electric screwed pipe is released, thus the effect that makes spool overcome spring force move, reach the purpose that changes oil circuit.The workpiece that coil is made up of the copper wire winding can produce electromagnetic force when energising.The material of the 2nd O type circle adopts nitrile rubber, is used for the aqueous vapor seal action between electric screwed pipe and coil.Plastic cap nut is used for fastening coil and body closely cooperates.Nameplate is used to identify valve group model.Plug is the device that is used to make things convenient for coil electricity.
In Fig. 1, left side coil electricity solenoid tube push rod is released, and spool overcomes Returnning spring power and the second chamber Y power of surging moves right, and the second chamber Y hydraulic oil directly returns the second runner T fuel tank by improved suitable slip-stream road; Body before ining contrast to, when spool overcomes Returnning spring power and the second chamber Y power of surging and moves right, the second chamber Y power of surging is back to the first chamber X by auxiliary hole, because it is less than length and sectional area to be back to the auxiliary hole of the first chamber X, backflow oil pressure bigger along stroke pressure loss and local pressure loss, back-flow velocity is slow, and the back pressure of formation is bigger, thereby causes the second chamber Y power of surging bigger; So the modified model body by the quick backflow effect of the second runner T, can bear higher pressure and flow under identical operating mode in handoff procedure.In like manner, the right side coil electricity is come to the same thing.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these mode of executions.Therefore, protection domain of the present utility model is limited by appended claims.
