Technical field
The present invention relates to a kind of solenoid valve, for example a kind of two-position three way proportional electromagnetic valve.Specifically, be the continuously adjustable magnetoresistive type proportional electromagnetic valve of a kind of stroke, direction and speed.
Background technique:
A kind of solenoid valve of the prior art adopts one group of d-c solenoid DM core, relies on certain electrical signal to make the solenoid valve iron core produce magnetic force, overcomes the spring pressure of moving iron core one end, opens ventilating hole.After the outage, moving iron core loses electromagnetic power, and spring handle moves the iron core pushed home, closes ventilating hole.The defective of this solenoid valve is to regulate the speed of air pressure output, snap action when reaching spring pressure, and only in prescribed stroke, play the effect of closing and opening valve.
The solenoid valve that another kind of the prior art is used for controlling the liquid road adopts two groups of independently electromagnetic coils, and it is installed on the valve seat abreast, adopts the mode of power on/off in turn, makes solenoid valve produce frequency and controls air pressure output speed.The defective of this solenoid valve is: control system can only be carried out the on-off type operation, uses inconvenience, is not suitable for the control utilization of a lot of occasions, and bulky, cost height, function dullness.
Summary of the invention
The purpose of this invention is to provide a kind of solenoid valve, it has overcome the defective of above-mentioned existing solenoid valve, not only can control the moving direction of spool constantly, stroke and speed, and compact structure, and volume is little, and cost is low.
Solenoid valve of the present invention comprises one group of electromagnetic coil that has the outer iron core yoke, and this coil axes is to being a tight fit in a hollow static iron core periphery that has the attaching nut.Place the moving iron core of a sliding type cylinder in this hollow static iron core, this moving iron core is made by magnetically soft alloy material.A spool is riveted in heart position therein, hollow static iron core bottom seals and the location with nonmagnetic substance, and it is a soft magnetic material that has center hole near attaching nut's one end, by this attaching nut static iron core is connected in a hollow push rod formula plastics valve body that has reseting pressuring spring.The hollow static iron core of solenoid valve of the present invention is three segments combined structures,, is divided into three sections vertically that is, and the two edges section is a soft magnetic material, and the centre is a nonmagnetic substance.
Preferably, the middle nonmagnetic substance on the described hollow static iron core is a copper.
As a kind of replacement of copper, the middle nonmagnetic substance of described hollow static iron core is an aluminium.
Preferably, putting into the thin varnished cloth of one deck in the gap of moving iron core and static iron core isolates.Can protect the sound iron core like this.
Preferably, at the gas port place of solenoid valve of the present invention one baroceptor is set, itself and a controller link, and transmit the air pressure signal of gas port to this controller.This controller connects described unicoil, and can flow through above-mentioned monocoil electric current according to the SC sigmal control that receives from described sensor, thus the motion of control spool.
Preferably, above-mentioned controller comprises potentiometer, is added on the sliding contact of potentiometer with the more weak direct current of energy, with the Current Control valve core movement of potentiometer two ends output.More preferably, above-mentioned controller also comprises triode amplifier, and the electric current at above-mentioned potentiometer two ends is controlled this monocoil electric current after triode amplifies, thus direction, stroke and the speed of control spool.
Particularly preferably be, have the parameter of setting in the above-mentioned controller, controller will compare with the parameter that sets from the signal of baroceptor.Control spool travel direction, stroke and speed according to result relatively.
Solenoid valve of the present invention is preferably a kind of two-position three way Proportional valve, and it is preferably a kind of two-position three way Proportional valve that is used for gas circuit.
During work, the adjustable DC electrical source of input in the electromagnetic coil in the solenoid valve of the present invention, produce magnetic field behind the coil electricity, be subjected to the moving cylindrical spool that drives unshakable in one's determination of magneto motive sliding type and overcome spring force, axially move, the hollow push rod that promotes valve body is opened ventilating hole, stroke that hollow push rod is opened and speed and input current intensity be varied to direct ratio, that is, electric current strengthens, and the aperture of valve increases.
According to the said structure of solenoid valve of the present invention, those skilled in the art are not difficult to find out that the present invention has overcome the above-mentioned defective of existing solenoid valve, not only can control the moving direction of spool constantly, stroke and speed, and compact structure, and volume is little, and cost is low.
In order to understand the present invention better, the preferred embodiments of the present invention are described below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the sectional view of a most preferred embodiment of the continuously adjustable solenoid valve of valve core movement of the present invention.
Fig. 2 is the amplification view of the hollow static iron core of the continuously adjustable solenoid valve of valve core movement shown in Figure 1.
Reference character:
1. valve casing 4 (2). the static iron core intermediate section
