Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.In addition, if below in described each mode of execution of the present invention involved technical characteristics do not form conflict each other and just can mutually combine.
As shown in Figure 1, small electric magnet valve thruster provided by the invention comprises permanent magnet 1, valve body 6, shell 2, coil 3, wire 4, spring 5, spool 7, sealing adjustment pad 8, jet pipe 9.Valve body 6 is made up of import valve body 61, lower valve body 63 and the magnetism resistent ring 62 be welded on therebetween, and magnetism resistent ring 62 reduces the magnetic loss of system; By armature 71 and spinning, the seal spool block 72 in armature 71 forms spool 7.
Permanent magnet 1 is connected by screw thread and outlet valve body 61, forms the I shape skeleton of coil winding with half I-shaped cylinder type valve body 6.Polyamide enamelled wire is directly outside valve body, and between I shape skeleton, composition coil 3, is drawn by the wire guide B be enclosed within outside coil 3 on shell 2 after the afterbody soldering well of wire 4 and enameled cable.
Spool 7 is arranged in the valve core channel formed with the valve body 6 be threaded and jet pipe 9.
Jet pipe 9 connects into the agent structure of valve by screw thread and valve body 6, comprises the import IN of valve body 6, MEDIA FLOW circulation passage C, valve core channel FXTD and outlet OUT; Linarity fluid passage optimizes design, reduces the volume and weight of thruster.
Spool 7 is arranged in valve core channel FXTD, and energy to-and-fro motion, wherein have in the armature 71 of spring mounting hole 7D and spring 5 is housed, and the import valve body 61 simultaneously having spring mounting hole 6D coordinates installation, seal spool block 72 is adjacent to the sealing strip MFD of jet pipe 9 under the pretightening force effect of spring 5; Jet pipe and valve bodyization design alleviate the weight of thruster.
Sealing adjustment pad 8 is arranged between jet pipe 9 and valve body 6, by changing the thickness of this pad to adjust working clearance δ between spool 7 (armature 71) and valve body 6 (import valve body 61) while sealing, and then the maximum opening of adjustment solenoid valve, thus meet the requirement of thruster flow.
Product of the present invention is directly connected with pipeline by the cone mouth screw thread of import IN, and during no electric circuit, under spring force and gas pressure effect, seal spool block 72 is pressed on the sealing strip MFD of jet pipe 9, and realize sealing, closed electromagnetic valve, thruster does not work; When the work of needs thruster produces thrust, to passing into 24V voltage drive signals, electromagnet suction overcomes gas pressure and spring 5 elastic force, inhale movable valve plug 7 (armature 71) motion, seal spool block 72 and jet pipe 9 sealing strip MFD depart from, solenoid valve is opened, and gas sprays from the outlet OUT of jet pipe 9, produces thrust; When not needing thrust, off voltage, electromagnet loses electromagnetic attraction, and under the effect of gas pressure and spring force, seal spool block 72 and jet pipe 9 sealing strip MFD realize sealing, and closed electromagnetic valve, thruster quits work.
MEDIA FLOW circulation passage C is designed in electromagnet by structural design by product of the present invention, makes total simple and compact; This structural design makes gas pressure become main seal power, and spring force mainly plays reset role, and therefore spring 5 size and elastic force are all less; Fluid passage C is in electromagnet, and operationally fluid can take away partial heat, reduces electromagnet warming velocity, increases life of product.
Actual tests table use, the latus rectum of this solenoid valve thrust is 2mm, and under the pressure of 2MPa, gas medium can effectively work, and sealing is reliable.The external dimension of thrust are Φ 20mm × 49.5mm, and weight is 97g, and under 24V direct voltage drive signal, speed of response is not more than 2ms.Its structure is simple, compact, and it is medium that volume is little, lightweight, the feature of fast response time can be applicable to aircraft posture control system.
Installation process of the present invention is as follows:
(1) check, clean all parts;
(2) the import valve body 61 of valve body 6 is screwed in permanent magnet 1 endoporus, form I shape skeleton;
(3) coil 3 is wound in the I shape skeleton of valve body 6 and permanent magnet 1 formation, passes after coil 3 tail end enameled cable and wire 4 soldering in the wire guide B shell 2; The polyimide enamelling cuprum round line that coil 3 can select temperature resistant grade higher;
(4) boss that the position that shell 2 contacts with valve body 6 has groove and a valve body matches and forms rotation inhibiting draw-in groove, avoids the rotation because of shell 2 to damage the wire 4 of drawing from shell 2 wire guide B; Shell 2 and permanent magnet 1 are welded to connect;
(5) spring 5 is put in the spring mounting hole 6D of valve body 6;
(6) seal spool block 72 spinning is entered in armature 71;
(7) spool 7 is put in the valve core channel FXTD of valve body 6, guarantee that spring 5 is put in the spring mounting hole 7D of armature 71 simultaneously;
(8) sealing adjustment pad 8 is put in valve body 6, by jet pipe 9 precession valve body 6, guarantee that jet pipe 9 and valve body 6 realize sealing.So far assemble complete.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present invention; not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
