Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, solenoid valve of the present utility model comprises valve component 1, outer magnetizer 2, coil 3, lead-in wire 4, pad 5, armature baffle plate assembly 6 and valve seat 7.Coil 3 is between outer magnetizer 2 and valve component 1, on valve component 1.Pad 5 is between armature baffle plate assembly 6 and valve component 1; By valve seat 7 armature baffle plate assembly 6 and pad 5 are pressed in the inner chamber of valve component 1.
Fig. 2 is valve component 1 structural representation.Valve component 1 is the chief component of solenoid valve, is the skeleton of whole solenoid valve, is one of magnetic circuit path of solenoid valve, and its upstream and propulsion system are by being threaded, and the downstream is connected by flange plate with thruster with satellite.Valve component 1 structure as shown in Figure 2: comprise two sections permeability magnetic material valve body inlet attacks 11 and valve body magnetism resistent ring 12, and two sections non-magnet_conductible material valve body connecting rings 13 and valve flange dish 14.They link together by welding manner.
Armature baffle plate assembly 6 is positioned at valve component 1 chamber, comprises nonmetal Sealing 61, baffle plate 62, spring 63 and armature 64, as shown in Figure 3.Nonmetal Sealing 61 is fixed on a side of baffle plate 62, and spring 63 is pressed in the opposite side of baffle plate 62 by armature 64, and armature 64 is fixedlyed connected with baffle plate 62.Spring 63 is three arm chip type springs.
For armature baffle plate assembly 6 is suspended in the solenoid valve, utilize radial rigidity big and the good S shape spring 63 of neutrality made component suspension.This suspension support mode makes and the armature light weight helps realizing quick response; And make the armature baffle plate assembly not with solenoid valve in wall friction, thereby have stable performance, switch reliability and sealing reliability height, the advantage that contamination resistance is strong.
The working principle of the utility model solenoid valve is: when solenoid valve lead-in wire 4 is set up operating voltage, because solenoid is an inductive element, electric current is pressed the index law increase in the coil 3, and the magnetic intensity of solenoid valve magnetic circuit increases, and the magnetic force that acts on armature baffle plate assembly 6 increases.When magnetic force can overcome the sealing force of spring 63, armature 64 setting in motions, valve port is opened.Because 6 motions of armature baffle plate assembly produce counterelectromotive force, coil current reduces until 6 stop motions of armature baffle plate assembly, and coil current increases by index law again to be opened fully until valve port.When solenoid valve cuts off the power supply, coil current descends and causes armature baffle plate assembly 6 magnetic forces to reduce, when magnetic force armature baffle plate assembly 6 setting in motions and produce anti-electromagnetism during less than spring force, coil current begins to rise, when 6 stop motions of armature baffle plate assembly, coil current stops to rise, and descends by index law again and closes fully until valve port.
In addition, because the processing more complicated of valve component 1, except will be with each constituent element welded together, also need the butt welded seam quality to examine, could guarantee the quality of product.Need be when therefore, valve component 1 each constituent element welds by certain welding sequence.At first valve body magnetism resistent ring 12 and valve body connecting ring 13 should be welded as a whole; Then again itself and valve body inlet attack 11 are welded; At last with this three and 14 welding of valve flange dish.For realizing pollution-free source, within all circulation passages, do not allow internal thread.Therefore need the corresponding outside frock of design and guarantee that by welding manner valve does not have the automatic pollution source.
After tested, the first natural frequency of present embodiment solenoid valve reaches 347.67Hz, compares with prior art and improves 3～4 times; The valve opening solenoid conformity reaches ± 0.3ms, closes conformity and reaches ± 0.8ms, compares with prior art and improves 2.5 times.Simultaneously, under the driving of existing drive circuit, the electromagnetic valve switch response time all realized＜target of 5ms, is significantly less than the switching response time of prior art.
The micrometeor solenoid valve of present embodiment, its weight is about about 70g, compares with solenoid valve on the existing star and has reduced more than 50%.
The solenoid valve of present embodiment carries out cleanliness and detects behind No. 1,000,000 switches, valve interior wall is compared with prior art with the fricative different sized particles numbers of armature component and reduced by 8～10 times, has improved the solenoid valve cleanliness greatly.The more important thing is that solenoid valve beats (promptly not passing through medium) and hunt leak through doing for 1,000,000 times, still can satisfy seal request; Considerably beyond the technical merit of existing product, realized no friction truly.
Certainly, under the situation that does not change its function, the equivalent transformation that carries out or alternative also falls into protection domain of the present utility model to each constituent elements of the present utility model, position relation and Placement.
The undocumented technology of the utility model specification belongs to techniques well known.
