Abstract
The invention discloses a micro electromagnetic valve which comprises an electromagnetic coil, a movable iron core, a valve body and a plunger tube, wherein the electromagnetic coil comprises a magnetizer, a flux sleeve, a magnetic shield and a coil; the upper end of the movable iron core is sleeved with a spring, the lower end of the movable iron core is sleeved with a diaphragm, the cost of parts is reduced by removing a fixing iron core. When the movable iron core is absorbed, the top end of the movable iron core does not contact with the inner bottom of the plunger tube; the noise is removed; and the production cost is reduced. A sealing chamber is formed by the plunger tube and the valve body; the plunger tube and the valve are sealed by a sealing ring; the valve body is connected with the plunger tube in a riveting way, so that complexes of the threaded connection are reduced. Copper foam and scrap iron generated by threaded connection are avoided. The electromagnetic valve coil is connected with the plunger tube by a snap spring; the valve body and the electromagnetic valve coil are tightly resisted, so that the angle of the electromagnetic coil can be freely adjusted as required without shaking the adjusted angle, therefore, greater space can be selected on connection; and the micro electromagnetic valve is more flexible to use.
Description
Technical field
The present invention relates to a kind of solenoid valve, relate in particular to a kind of miniature electromagnetic valve.
Background technique
At present, upgrading because of small household electrical appliance, formerly with electromagnetic pump, spray water heating board and the steam flow and the steam heat that produce steam do not reach requirement, develop a kind of steam flow of controlling, and steam is heated again, to produce stronger heat small household electrical appliance, become the certainty of modern technologies, and will realize the solenoid valve that above-mentioned performance just needs a kind of compact structure, energy high temperature high voltage resistant.But the solenoid valve that does not have compact structure, energy high temperature high voltage resistant in existing steam electromagnetic valve.
Chinese patent notification number CN201071959Y, June 11 2008 day for announcing, a valve body is disclosed, a coil block and a safe slide bar assembly, on valve body, there are two built-in air cavity spaces, between upper and lower two built-in air cavitys, be provided with through hole, coil block is by hollow cylindrical coil, secured core, copper bar, movable core forms, safe slide bar assembly is by the aluminium bar that slides, spring, jump ring, exhaust port forms, at slip aluminium bar neck, have groove, along slip aluminium bar movement direction, be provided with jump ring, jump ring is fixed on plastic cover plate, this apparatus structure is reasonable, volume is small and exquisite, with low cost, assembling easily, can be widely used in cooking appliance, industrial electrical equipment, miniature boilers etc. have on the product of water vapour.But this steam electromagnetic valve can not bear the High Temperature High Pressure after product up-gradation, cannot meet the upgrading requirement of product.
Summary of the invention
Of the present invention have a favorable sealing property, and compact structure, noise free can high temperature high voltage resistants, coil can 360 the feature of the random rotation angle of degree, be applicable in various liquid transporting apparatus or system, having solved existing miniature electromagnetic valve coil can not rotate, the problem that noise is large.
For solving the problems of the technologies described above, the present invention is solved by following technical proposals:
A miniature electromagnetic valve, comprises electromagnetic coil, valve body and plunger tube, and electromagnetic coil comprises magnet case, concentrating flux sleeve, magnetic shield and coil.Its design main points are that the outer ring of described plunger tube is provided with the first concentrating flux sleeve and the second concentrating flux sleeve, between the first concentrating flux sleeve and the second concentrating flux sleeve, be provided with magnetic shield, the movement effects of movable core in plunger tube further improved, it is the environment that middle end produces relative low-intensity magnetic field, plunger tube and valve body form seal chamber, and between plunger tube and valve body, with seal ring sealing, valve body is connected with riveting method with plunger tube, reduce be threaded loaded down with trivial details, avoided producing because being threaded copper foam, iron filings.
As preferably, electromagnetic coil inside is provided with movable core, compares with technology in the past, has made secured core into movable core, during the battery valve work that makes, can not produce noise.
As preferably, movable core upper end is socketed with spring, and lower end is socketed with diaphragm, has cancelled secured core, reduces cost of parts, and during movable core adhesive, top and plunger tube inner bottom part do not touch, and have eliminated the generation of noise, have reduced cost of production.
As preferably, between the magnet case on electromagnetic coil and concentrating flux sleeve, magnetic shield is installed, the movement effects of movable core in plunger tube further improved, middle end produces the environment of relative low-intensity magnetic field.
As preferably, being connected of coil and plunger tube used jump ring to connect, and with stage clip, holds out against between valve body and electromagnetic coil, makes electromagnetic coil can arbitrarily adjust with the need angle and adjusts angle simultaneously and can not rock again, on connecting, there is greater room to select, used more flexible.
The invention has the beneficial effects as follows: have favorable sealing property, compact structure, noise free, can high temperature high voltage resistant, the random feature of regulating winding angle, is applicable in various liquid transporting apparatus or system.

Embodiment
Below in conjunction with attached Fig. 1 and 2 and embodiment, the present invention is described in further detail.
embodiment:
A kind of miniature electromagnetic valve, comprise electromagnetic coil 21, valve body 1 and plunger tube 4, between electromagnetic coil 21 and valve body 1, stage clip 5 is installed, electromagnetic coil 21 also comprises magnet case 9, coil 12, concentrating flux sleeve 7 and magnetic shield 8, plunger tube 4 is used riveting method to be connected with valve body 1, with seal ring 2 sealings.
Electromagnetic coil 21 inside are provided with movable core 6.
Movable core 6 upper end socket springs 11, lower end is socketed with diaphragm 3.
Between magnet case (9) on electromagnetic coil (21) and concentrating flux sleeve (7), magnetic shield (8) is installed, the movement effects of movable core (6) in plunger tube (4) further improved, middle end produces the environment of relative low-intensity magnetic field.
Plunger tube 4 does not have secured core 6, can not produce noise.
Coil 12 and plunger tube 4 use jump rings 10 are connected and fixed, and valve body 1 is fixedly connected with electromagnetic coil 21 use stage clips 5.
When electromagnetic coil 21 energisings, the energising of coil 12, generates an electromagnetic field, and movable core 6, under the effect of electromagnetic field, produces active force upwards, and now valve body 1 is opened.After circuit disconnects, coil 12 does not have electric current to pass through, and electromagnetic field also disappears thereupon simultaneously, and movable core 6 has also lost the active force making progress, and under spring 11 effects of movable core 6 upper end sockets, movable core 6 moves downward simultaneously, and valve body 1 is closed.Above process completes a work cycle of the present invention.
In a word, the foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to the covering scope of patent of the present invention.
