Description
Technical field
The present invention relates to miniature electromagnetic valve technical field, and in particular to a kind of miniature electromagnetic valve.
Background technology
Electromagnetic valve is, with the industrial equipment of Electromagnetic Control, for controlling the automatic foundamental element of fluid, to belong to executor,
It is not limited to hydraulic pressure, pneumatic.Electromagnetic valve can coordinate different circuits to realize expected control, and the precision that controls and flexibly
Property can ensure.Miniature electromagnetic valve is typically pet-valve class, its be widely used in household electric appliances, office equipment, automobile industry, point
The industries such as analyzer device, medical apparatus and instruments, machine-building.It is tubular that miniature electromagnetic valve currently on the market is arranged on air hermetic by one
Coil composition on armature, the armature is a part for valve body, and is placed in valve port.Transported by the control system of switching on or off electricity armature of coil
It is dynamic, so as to adjust direction, flow, the speed etc. of medium.This coil armature type electromagnetic valve used on market exists following several
Individual problem：1) under in working order, coil electricity can generate heat, when its work for a period of time after, its surface and environment temperature can be very
Height, this will have a significant impact to the fatigue life worked under its high temperature；2) coil armature structure causes its volume unlimited
Compression.Therefore for the very limited amount of occasion in space, there is limitation in its application.
The content of the invention
To solve the problems, such as above-mentioned prior art, the invention provides a kind of miniature electromagnetic valve, the miniature electromagnetic valve
Simple structure, volume significantly reduces, and will not produce amount of heat causes electromagnetic valve temperature to raise.
Realize that the technical scheme that above-mentioned purpose of the present invention is taken is：
A kind of miniature electromagnetic valve, including shell, support, circuit board, plug, slide bar, spring and two nitinol alloy wires, outward
Shell-side face is provided with air intake, and top is provided with gas outlet, and circuit board is installed on outer casing bottom by support, circuit board two ends central authorities
Binding post is arranged with, the lower end of slide bar is fixed in the central authorities of circuit board, and spring is sleeved on slide bar, and spring upper end is fixed on
Plug is central, and plug is got lodged on gas outlet, and slide bar coordinates with plug central space, and two nitinol alloy wire upper ends are each attached to
In plug central authorities, and the upper end of two nitinol alloy wires is connected, and the lower end of two nitinol alloy wires is separately fixed at two binding posts
On, and two nitinol alloy wires are connected by binding post with circuit board.
Compared with prior art, advantages of the present invention and effective effect are：
1) the miniature electromagnetic valve simple structure, small volume, the narrow and small position for being particularly suitable for applications in limited space uses.
For example, if realizing that inflation/deflation and guarantor's airway dysfunction at least want two using the coil armature type electromagnetic valve commonly used on market
With sharing, a Fa0520 produced such as Shenzhen Ji Chuanxing companies of the electromagnetic valve minimum made now, its volume is length
28mm width 15mm thickness 13mm.If using the nitinol alloy wire electromagnetic valve in the invention, made in circuit board two-sided (due to circuit
Plate accounts for that volume is larger, and circuit board adopts printed on both sides, and the volume shared by circuit board can be greatly reduced) in the case of, its volume
Long 20mm width 10mm thickness 6mm is may decrease to, electromagnetic valve more on the market is lighter, thinner.Installing space have limitation massage armchair,
Automotive seat etc., advantage becomes apparent from.
2) in the miniature electromagnetic valve, nitinol alloy wire can make hairline carefully and two symmetrical, sends out when it is powered
Heat is extremely little, almost can ignore, and is especially suitable for being used under high temperature.By experiment test, electromagnetic valve on the market is not
How pipe improves heating effect, and after working 10 minutes, its surface can substantially become boiling hot.By the electromagnetism of minimum model used on the market
Valve, the Fa0520 that Ji Chuanxing companies in Shenzhen as previously mentioned are produced exists respectively with the new micro electromagnetic valve in the present invention
Temperature test is carried out under 20 ° of room temperature.Test finds that both treat that both of which has worked 1 hour when 12v unidirectional currents are accessed
Afterwards (both of which has reached thermal steady state, and surface temperature is stable and will not change) determines respectively its surface temperature, market
The surface temperature of the electromagnetic valve of upper minimum model used increases 5 ° or so, and the electromagnetic valve in the present invention only increases 0.6 °,
As can be seen here, electromagnetic valve of the invention is particularly suitable for hot environment.
3) nitinol alloy wire has a good wear-resisting, corrosion resistance, and such as its corrosion resistance is medical stainless better than best at present
Steel, in can be used for the corrosive environment of bad environments.
4) super-elasticity of nitinol alloy wire makes its admissible stroke range bigger, and the expansion and contraction of such as nitinol alloy wire exists
More than 20%.
5) nitinol alloy wire has high damping characteristic, and its damping characteristic is higher than common spring 10 times, can be using vibrations
Environment.
6) long service life, the fatigue life of nitinol alloy wire reaches 7 powers of 1*10.
