Abstract
The utility model relates to a normal open electromagnetic valve. The valve body is provided with an upper and a lower valve seats, and an upper and a lower sealing pieces are correspondingly arranged on a pull rod. Under the normal open state, the pull rod is disposed at the normal open position with the function of a spring, the upper and the lower sealing pieces are separated from the upper and the lower valve seats, the electromagnetic valve opens. A movable iron core drives the pull rod overcoming the spring force and moving upwards with the function of the electromagnetic force when electrifying, thus, through holes of the upper and the lower valve seats are separately sealed by the upper and the lower sealing pieces, the electromagnetic valve closes. The utility model avoids the influence of the pressure of the medium, and has reliable sealing, flexible opening and closing, and long service life. A magnet separating tube is isolated from the medium without being corroded. The utility model can be widely used for different mediums under different pressure.
Description
Affiliated technical field
The utility model relates to a kind of normally open solenoid valve that is used for various flowing medium controls.
Background technique
At present, known normally open solenoid valve is mainly by valve body, diaphragm unit, bonnet, valve rod, auxiliary-seat is formed with the Electrical heads that has static iron core and moving iron core, under the normally open of solenoid valve, two media are arranged in the solenoid valve, main passage is the main valve passage, flow to outlet end by the main valve seat through hole of entrance point on valve body, the Sealing of main valve passage is a diaphragm unit, another passage is secondary valve passage, enter the diaphragm unit epicoele by the damping hole of entrance point on diaphragm unit, flow to outlet end through the auxiliary-seat through hole again, the Sealing of secondary valve passage is in the pull bar lower end, when solenoid valve is switched on, moving iron core is by the static iron core adhesive, drive pull bar to moving down, the secondary valve seal of pull bar lower end is pressed on the auxiliary-seat, seal the auxiliary-seat through hole, close secondary valve passage, at this moment, medium can continue to flow into the diaphragm unit epicoele by the damping hole on diaphragm unit, pressure medium in the diaphragm unit epicoele is constantly raise, after the diaphragm unit upper cavity pressure surpassed the electromagnetic valve outlet end pressure, diaphragm unit was pressed on the main valve seat downwards under the effect of pressure reduction up and down, sealing main valve seat through hole, closed electromagnetic valve.After the solenoid valve outage, moving iron core upwards lifts under the effect of spring, drive on the pull bar and move the open auxiliary valve passage, medium in the diaphragm unit epicoele flows out by secondary valve passage, and pressure reduces, when the pressure medium in the diaphragm unit epicoele drops to a certain degree, diaphragm unit be subjected to from the pressure medium that makes progress of solenoid valve entrance point greater than its be subjected to from the downward pressure medium in the epicoele, diaphragm unit lifts, and opens the main valve passage, and solenoid valve recovers normally open.Since this solenoid valve main valve and secondary valve open and seal the influence that all is subjected to pressure medium, so exist several like this, the one, cross when low when pressure medium, the pressure that the solenoid valve energising acts on the diaphragm unit when closing is little, poor sealing performance, easily leakage; The 2nd, when pressure medium was too high, spring force was less relatively, and pull bar can not pushed up in solenoid valve outage back, secondary valve is not opened, and as strengthening spring force, the active force in the time of can making the solenoid valve energising again between static iron core and the moving iron core is less relatively, do not overcome spring force, valve closes incessantly; In addition, this solenoid valve also exists the diaphragm unit life-span short, and medium can flow in the plunger tube of moving iron core, easily with defectives such as plunger tube corrosion.
The model utility content
For overcoming the above-mentioned defective of prior art, the utility model provides a kind of normally open solenoid valve, and its switch is not subjected to the influence of pressure medium, is applicable to the medium of various pressure, and its component life is long, and medium and plunger tube are isolated, and can not produce the corrosion to plunger tube.
The technical solution of the utility model is: normally open solenoid valve comprises valve body, bonnet, pull bar, spring and the Electrical heads that has static iron core and moving iron core, inner chamber is arranged in the valve body, lumen openings is in the entrance point and the outlet end of solenoid valve, bonnet places valve body top, fuse with valve shell, pull bar passes bonnet, one end is positioned at body cavity, the other end connects with moving iron core, spring one end is fixed, the other end is connected with pull bar, Electrical heads is positioned at the valve body top, also have upper valve base and lower valve base in described valve body, through hole on the upper valve base and the through hole on the lower valve base all are communicated with entrance point and outlet end by inner chamber, and described pull bar passes upper valve base and lower valve base through hole, and on the position of distance upper valve base through hole and lower valve base through hole equidistance, have Sealing and lower seal, the shape and size of last Sealing and lower seal match with the shape and size of upper valve base through hole and lower valve base through hole, can form the sealing to upper valve base through hole and lower valve base through hole.Under normally open, pull bar is under the effect of spring, be positioned at the normally open position, the through hole of upper-lower seal part and last lower valve base is separated, medium flows into body cavity by entrance point, through hole to outlet end through last lower valve base flows out respectively, when solenoid valve is switched on, moving iron core and static iron core adhesive in the Electrical heads, moving iron core drive pull bar overcomes spring force and moves up, and the upper-lower seal part is pressed on respectively on the lower valve base, seals valve seat through-hole up and down, the passage of cut-out from the entrance point to the outlet end, closed electromagnetic valve.
The beneficial effects of the utility model are: because the utility model has two Sealings up and down, two pressure equal and opposite in directions that Sealing is suffered from entrance point (or outlet end) medium, direction is opposite, cancel out each other, therefore the seal action of the motion of pull bar and Sealing all is not subjected to the influence of pressure medium, overcome prior art poor sealing under low pressure, under high pressure move malfunctioning defective, the intensity of the Sealing that is adopted and life-span are much larger than the intensity and the life-span of the diaphragm unit of existing solenoid valve in addition, improved the working life of solenoid valve, simultaneously owing to adopt good sealing structure and material, medium can not flow in the plunger tube, has avoided the corrosion to plunger tube.
Description of drawings
