Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Consult shown in Fig. 1, the utility model provides a kind of miniaturization ultra high speed solenoid electromagnet, comprise valve seat 1, steel ball 2, retainer 3, push rod 4, bearing support 5, valve body 6, armature 7, buting iron 8, spring 9, coil 10, spring seat 11, the first seal ring 12a, the second seal ring 12b, the 3rd seal ring 12c, yoke 13, the first sliding bearing 14a and the second sliding bearing 14b, valve seat 1 is ring, inside establish circular hole medium inlet 1a, and be connected by interference fit with valve body 6; Described retainer 3 connects as one with valve body 6, described bearing support 5 is circular, the first sliding bearing 14a and the second sliding bearing 14b are arranged on inner hole of bearing seat and by coordinating with valve body 6 and connect as one, described push rod 4 is integrated with armature 7 riveted joints, and the small-sized superelevation switch electromagnetic valve of described lightweight volume is not more than 11.7
the small-sized superelevation switch electromagnetic valve of described lightweight diametric(al) is not more than 19 mm, the small-sized superelevation switch electromagnetic valve of described lightweight weight is not more than 52g, and the small-sized superelevation switch electromagnetic valve of described lightweight all can realize sealing to gas and liquid medium under 2MPa pressure and speed of response is less than 0.9ms.
Valve body 6 is made up of soft magnetic material, is multistage round column structure, is radially provided with media outlet 6a, and cylindrical is provided with the worm structure for location is installed, and surface is through anti-corrosion treatment.Armature 7, between bearing support 5 and buting iron 8, and can move vertically.Coil 10 is provided with signal and inputs the first electric mortiser pin 10a and the second electric mortiser pin 10b, on the second electric mortiser pin 10b, is provided with circular groove (not shown), for placing the first seal ring 12a.Armature 7 and buting iron 8 are made up of soft magnetic material, and surface all scribbles non-magnetic anticorrosive coat, and anticorrosive coat thickness is 0.02～0.04mm.Between steel ball 2 and valve seat 1, be wire sealing, and valve seat 1 is through stiffened preservative treatment.
As shown in Figures 2 and 3, when no electric circuit, it is upper that working medium acts on steel ball (sequence number 2 in Fig. 1) by import P by the medium inlet (sequence number 1a in Fig. 1) on valve seat (sequence number 1 in Fig. 1), produces pressure medium to the right
f t , spring (sequence number 9 in Fig. 1) acts on generation spring force left on armature
f t , act on (sequence number 2 in Fig. 1) on steel ball by the push rod (sequence number 4 in Fig. 1) connecting as one with armature (sequence number 7 in Fig. 1).Due to
f t much larger than
f l , the two make a concerted effort (being called sealing force) producing left, is pressed in steel ball (sequence number 2 in Fig. 1) on valve seat (sequence number 1 in Fig. 1).Owing to contacting for circular line between steel ball and valve seat, area of contact is very little, and sealing force left produces very large pressure on the surface of contact between steel ball and valve seat, i.e. seal pressure is realized medium by import P sealing A to outlet.Steel ball (sequence number 2 in Fig. 1) is approximate positive ball-type, the effect of sealing depends on the size that sealing is left made a concerted effort on the one hand, depend on the other hand the quality of processing of valve seat (sequence number 1 in Fig. 1) and steel ball (sequence number 2 in Fig. 1) surface of contact, because sealing is made a concerted effort larger, when actual use, can produce certain distortion by compressed metal, reach good sealing effect.Because sealing surface is Structural Hardware, and steel ball (sequence number 2 in Fig. 1) and valve seat (sequence number 1 in Fig. 1) all through stiffened, processing has improved hardness, therefore such shape metallic leak-proof structure can be realized 1,000 ten thousand above shocks and not make seal failure.
In the time of energising, electromagnet produces electromagnetic attraction to the right
f i act on armature (sequence number 7 in Fig. 1) upper,
f i much larger than spring force left
f t , promotion armature (sequence number 7 in Fig. 1) moves right and is fitted on buting iron (sequence number 8 in Fig. 1).Push rod (sequence number 4 in Fig. 1) moves to right, and steel ball (sequence number 2 in Fig. 1) is at pressure medium
f l effect under move right, medium is as the connection between entrance P and media outlet A, medium is flowed out and is supplied with downstream mechanism by A mouth.Being provided for of retainer (sequence number 3 in Fig. 1) guarantee steel ball (sequence number 2 in Fig. 1) in the time of electromagnetic valve work all the time in certain limit, in such scope, steel ball (sequence number 2 in Fig. 1) can act on all the time valve seat (sequence number 1 in Fig. 1) and above not make seal failure in the time of solenoid valve power-off.Between yoke (sequence number 13 in Fig. 1) and valve body (sequence number 6 in Fig. 1), for metal flat contacts, through riveted joint distortion yoke (sequence number 13 in Fig. 1), valve body (sequence number 6 in Fig. 1) is fitted tightly in the upper realization sealing of yoke (sequence number 13 in Fig. 1).Equally, between buting iron (sequence number 8 in Fig. 1) and yoke (sequence number 13 in Fig. 1), also realize sealing.Coil (sequence number 10 in Fig. 1) right-hand member is provided with the first seal ring (sequence number 12a in Fig. 1), make to have realized end face seal between coil (sequence number 10 in Fig. 1) and buting iron (sequence number 8 in Fig. 1), between buting iron (sequence number 8 in Fig. 1) and spring seat (sequence number 11 in Fig. 1), realize sealing by mechanical structure, this mechanical structure can be that interference fit or be threaded adds structure glue and fills thread pitch and realize.Thus, solenoid valve is in the time of energising work, and medium only can flow out by the outlet A of solenoid valve.Because solenoid valve has the speed of response that is less than 1ms, while adopting pwm signal control, for example adopt the frequency of 200Hz, along with the difference of signal dutyfactor, steel ball (sequence number 2 in Fig. 1) is though that fast reciprocating moves the alternately break-make and the make-and-break time vacuum that realize between P mouth and A mouth is more proportional than the difference of signal, and the flow that medium flows into A Kou Hou mechanism is certain proportion relation with signal.When one timing of A Kou Hou mechanism cavity volume, can realize the proportionate relationship of A Kou Hou mechanism cavity volume internal pressure with solenoid valve input signal.For example, while adopting fixed value duty ratio, as 50% dutycycle, after A mouth, the pressure of cavity volume, due to high speed break-make and the solenoid valve sealing of solenoid valve, can maintain a stable value.
Practical application shows, this solenoid valve, under 2MPa pressure, uses gas all can effectively work as medium as medium or liquid, and sealing is reliable.Solenoid valve volume only 11.7
, maximum diameter 19mm, weight 52g.To liquid medium, rated pressure down-off is greater than 5L/min, gas medium rated pressure down-off is greater than to 200L/min, and speed of response is less than 0.9ms.While adopting the pwm signal driving that high level 24V, frequency are 200Hz, its dutycycle operating range is 16%～84%.Its volume is little, lightweight, the feature of fast response time can be widely used in has strict restriction to require again electromagnet to have the device of ultra high speed speed of response to volume and weight, as attitude of flight vehicle, control system etc.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to these embodiments' multiple modification, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be limited to these embodiments shown in this article, but will accord with principle disclosed herein and features of novelty the widest consistent scope.
