Embodiment
Technical scheme is illustrated with embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, being fixed with valve element on a kind of electromagnetic dosing pump with valve arrangement of the present invention, 1, its valve, valve element leads to
Cross taper spring washer 8 to be fixed on valve seat 1, the valve core upper sleeve is provided with external power supply coil, valve element includes setting in pump line 2, pump line 2
There are the first card rank 11 and the second card rank 12, card rank is the 3rd card stage structure, and the first card rank 11 and second blocks rank 12 by the content of pump line 2
Chamber is divided into admission chamber, three parts of compression chamber and fluid ejection chamber；Compression cavity inner sleeve has the dynamic magnetic tube 3 for prolonging cavity wall up and down motion, moves
The two ends of magnetic tube 3 are respectively equipped with the compression spring A and compression spring B offseted with the first card card rank 12 of rank 11 and second, move magnetic tube 1
Inner via hole bottom is provided with the 3rd card rank 13, and upper end blocks to block up on rank 14, the 3rd card rank 13 provided with the 4th through hole end socket 23, through hole envelope
First 23 offset above with tower spring 33 and the 4th card rank 14 of the dynamic upper end of magnetic tube 3, and block in tower spring 33 and the 4th
Pad 41 is provided between rank 14, plays a part of slowing down abrasion.
Operationally, move magnetic tube 3 to move up and down in overall, be prevented effectively from the compression spring and seal plug due to movable valve plug
What compression spring was set together, in long-time is moved back and forth, the friction between spring and tube wall and spring and plug is made
Easily worn and torn into spring, so that the problem of occurring fracture defect.Feed liquor plug mouthful 6, using resistant material, on feed liquor plug mouthful 6
Side is provided with the second unidirectional end socket 22, and the second unidirectional end socket 22 offsets above with compression spring C with the second card rank 12.In fluid ejection chamber
End is provided with nozzle 7, is provided with the first unidirectional end socket 21 in the first card rank 11 top, the first unidirectional end socket 21 above and nozzle 7 it
Between provided with the compression spring D that offsets.2 upper tube halfs of pump line and the mutual fit linking of lower tube half, by laser welding, structure is more steady
It is fixed, O-ring is provided between linking tube wall, the design avoids O-ring from being in contact with corrosive liquid, the middle part of pump line 3 is provided with magnetic partiting ring
5。
Through hole end socket 23, the first unidirectional end socket 22 of unidirectional end socket 21 and second are mushroom and use PTFE material, resistance to
Corrosion prevents the two-way leakage of valve element using mushroom-shaped end socket simultaneously, invention using resistant material can for corrosive liquids or
Use, or used in the metering conveying operating mode of acid solution with a small amount of impurity liquid, such as conveyed in ceramic ink jet printer
Ink is used.Invention is a kind of electromagnetic dosing pump with valve arrangement.Coil 15 carries metallic plug, is responsible for external electricity
Source.The inside of coil 15 is the valve element of pump, mainly includes water inlet tap 2 and faucet 14, and is placed with O at both binding sites
Type circle 16, and be combined together by the connection of septal funnel 7 and laser welding, it is solid and reliable.The water inlet tap 2 that welds together and go out
Water nozzle 14 constitutes valve element, the countersunk head position in the hole of coil 15 is stuck in by the outer steps of faucet, the other end set in hole
Upper conical spring washer 6 realizes the fixation between valve element and coil 15.
Invention is external AC24V/50HZ power supply operating mode in use.External two are also needed in use
Pole pipe, makes the front half section sine wave of AC power play forward conduction, and the second half section plays cut-off.
When forward conduction, the coil of electromagnetic dosing pump can produce electromagnetic field, now move magnetic tube 3 by electromagnetic force
Afterwards, it can move downward and compress compression spring B.At this moment the volume of admission chamber can be reduced, and inner air can be discharged.Work as alternating current
During the second half section of source sine wave, because the cut-off of diode is acted on, coil 15 must not be electric, and electromagnetic force disappears, and moves magnetic tube 3 in compression
Original position is returned under compression spring B spring-force driven dual.Now admission chamber volume increase, but inner air density and sky
Atmospheric pressure reduces to produce vacuum.In the case of outside atmospheric pressure is more than admission chamber air pressure, the second unidirectional end socket 22
Overcome the active force of little spring 4 and moved toward delivery port direction, so that the feed liquor plug mouthful 6 of water inlet and the second unidirectional end socket
There is space between 22.And outside liquid is pressed into the admission chamber of vacuum under atmospheric pressure effect by this space
It is interior.So that being filled with liquid inside admission chamber.When AC power enters the front half section of next sine wave period, coil
Under the effect of electric current forward conduction, electromagnetic field can be produced again.Dynamic magnetic tube 3 can be moved downward and compressed by after electromagnetic force
Compression spring B, now liquid inside admission chamber compressed.Because the second unidirectional end socket 22 and compression spring C35 structures
Into unidirectional valve action, water inlet passageway has been cut off, and liquid just can only be by promoting the turriform spring 33 of through hole end socket 23
Hence into the inside of the 3rd card rank 13.Through hole end socket 23 and turriform spring 33 combination also plays unidirectional valve action, liquid
Body enters behind the inside of the 3rd card rank 13, it is impossible to flow back.
When AC power sine wave enters the second half section again, dynamic magnetic tube 3 is returned to original position, now blocks rank 13 the 3rd
Internal liquid is extruded and by the circular hole of pad, and compression spring A32 pushes top open close to the second unidirectional of delivery port position
The compression spring C35 of end socket 22, is flowed into fluid ejection chamber from gap.The second unidirectional end socket 22 and compression due to delivery port position
The liquid that spring C35 is constituted in one-way valve structures, fluid ejection chamber can only spray from nozzle 7.
Using the alternating cyclical of power supply, spray feed liquid process after water suction is completed.By adjusting inside the frequency of power supply, pump
The reciprocation period of dynamic magnetic tube 3 be changed, so as to change the output flow of liquid, play a part of metering.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, thus it is all according to
The equivalence changes that structure, shape, the principle of the present invention is done, all should be covered by within protection scope of the present invention.
