Abstract
The utility model discloses a low pressure gas path electromagnetic valve. Coil frameworks are wound with a group of starting coils and a group of sustaining coils in an equidirectional mode, the front part inside sleeves is fixedly connected with fixing magnetic cores, and back sections of the sleeves are provided with moving magnetic cores with T-shaped cross sections, making big ends of the T-shaped moving magnetic cores positioned outside of a back end of the sleeves, and increasing magnetic circuit areas. Acting ends of the moving magnetic cores are connected with acting rods.
Description
The utility model relates to a kind of solenoid valve.
Existing gas circuit low-voltage solenoid valve is by open valve and keep valve and form, and open valve and keep valve and constitute by line bag and magnetic core, and all serve as reasons moving magnetic core the and decide bimag that magnetic core is formed of magnetic core is opened the push rod that connects on the valve actuation magnetic core and is kept the push rod that the valve actuation magnetic core even goes out and contact.When open valve was switched on, its moving magnetic core moved and drives the moving magnetic core keep valve and move in the same way, makes two magnetic cores keeping valve fit, and guarantees valve open and long-term work.But this solenoid valve needs two independent solenoid valves forms complex structure, cost height, and its adhesive face of keeping valve is a minute surface, this can make minute surface destroy owing to the burn into action of rust under poor working environment, then keeps valve and loses its function, and working life is very short.
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of simple in structure, and cost is low, the low pressure gas way solenoid valve of long service life.
Technical solution of the present utility model:
A kind of low pressure gas way solenoid valve, it includes housing (1) and coil rack (2), housing (1) middle part is connected with non-magnet material sleeve (3), housing (1) tail end is connected with the sealing gland (4) of non-magnet material, coil rack (2) is positioned between sleeve (3) outer wall and housing (1) inwall, and compress by gland (4), it is characterized in that on coil rack (2), being wound with in the same way one group of starting coil (5) and one group and keep coil (6), leading portion is fixed with and decides magnetic core (7) in sleeve (3), the interior back segment of sleeve (3) is provided with the moving magnetic core (8) that the cross section is the T type, the big end that makes the T type move magnetic core (8) is positioned at the outer end of sleeve (3) rear end, to increase the magnetic circuit area, be connected with actuating rod (9) at the effect end that moves magnetic core (8).
The utility model adopts single solenoid valve to form, its designs simplification, cost reduces, and adopting two-wire and coiling bag and cross section first is the moving core structure of T type, make that it can startup work under the low pressure situation, can under the low power consuming state, keep work again, its adhesive face is the general work face, need not to be minute surface, and this general work face can carry out surface treatment, so the corrosion protection of the utility model adhesive face, anti-corrosion function increase greatly, can use under various abominable gas circuit environment, working life, big leap ahead had very big social benefit and economic benefit.
Fig. 1 is the structural representation of the utility model front end for the effect end;
Fig. 2 is the structural representation of the utility model rear end for the effect end.
As Fig. 1,2, the adhesive end that is positioned at sleeve (3) of deciding magnetic core (7) and moving magnetic core (8) of the present utility model is preferably the tapered end that matches, to reduce the gap length in the magnetic circuit.The T type moves in the best gland (4) with housing (1) rear end of the big end of magnetic core (8) through matching.The effect end of moving magnetic core (8) can be at front end, and decide magnetic core (7) and have through hole this moment, and actuating rod (9) is connected with moving magnetic core (8) front end and passes from the through hole of deciding magnetic core (7).As Fig. 1.The effect end of moving magnetic core (8) also can be in the rear end, and decide magnetic core (7) this moment is solid body, and gland (4) has through hole, and actuating rod (9) is connected the big end center, rear end of moving magnetic core (8) and stretches out from the through hole of gland (4).As Fig. 2.Starting coil of the present utility model (5) and keep coil (6) can two-wire and around, also can be single separately around.
Working principle of the present utility model following (is example with Fig. 1).During use, actuating rod (9) front end contacts with the sealing gasket at valve assembly vent place.Starting coil (5) and keep coil (6) and draw three leads (10), wherein one is public ground wire.Starting coil (5) connects the instantaneous power output end of low-voltage DC source controller.The line footpath of keeping coil (6) usually is thin, and the number of turn is many.During work, the low-voltage DC source controller provides a transient current to starting coil (5), provides a constant voltage to keeping coil (6) simultaneously, makes them produce magnetic field.Under the effect in magnetic field, moving magnetic core (8) moves to deciding magnetic core (7), until two identical tapered end face adhesives.Because moving magnetic core (8) is a T type structure, its big end has increased the magnetic circuit area, and magnetic resistance is reduced, and magnetic intensity increases, so make the active force (comprising tripping force and maintenance energy) of moving magnetic core (8) adhesive face increase, guarantees its functional reliability., drive its actuating rod (9) and move forward when adhesive is moved at moving magnetic core (8), push the sealing gasket at valve assembly vent place open, thereby with valve open.Keep coil (6) dead electricity in case have a power failure, magnetic field disappears, and then the sealing gasket at assembly vent place resets under its Packing spring effect, and the assembly vent is closed.Simultaneously, will move magnetic core (8) pushed home by actuating rod (9).Front end sleeve (3) and decide seal ring (11) between the magnetic core (7) and the seal ring (12) between sleeve (3) rear end and the shell (1) is the leakage of its interior media gas when being used for preventing valve assembly work among the figure.
Stretch out if the effect end, only needs that actuating rod (9) is moved to rear end gland (4) at the rear portion, valve assembly also is positioned at the rear portion, working procedure and top identical, and just the action of actuating rod (9) is by promoting to become pulling.Effect is all very good.
