Abstract
The utility model provides a corrosion-resistant electromagnetic valve which adopts anticorrosive rubbers or fluoroplastics to make a valve core. The end of the push rod of the valve core is inlaid and coated in the valve core body to cause the valve core to be fixed on the push rod of the valve core, and the upper part of the valve core in a valve core chamber is provided with a spiral anticorrosive sheathing, which is made of rubbers or fluoroplastics and provided with spiral springs inside integrally connected with the valve core. The push rod of the valve core is positioned in the sheathing and isolated with the valve core chamber, the upper end opening of the anticorrosive sheathing is provided with a sealing hood which is tightly pressed and fixed by the upper cover of the valve core chamber and a sealing pressing plate and seals the valve core chamber, so that corrosive liquid passing through the interior of the valve is difficult to leak to the points of an electromagnet and the push rod of the valve core. The utility model has the advantages of simple structure, low cost, reliable anticorrosion property, etc.
Description
The utility model relates to a kind of solenoid valve, particularly a kind of anticorrosion solenoid valve.
Carry the pipeline of liquid, alkali or other corrosive liquids will use anticorrosion valve to control its switching, particularly some transfusion mains and the valve that is not easy to the staff operating position will use the electromagnetic valve or the pneumatic valve of automatic control usually.Because the solenoid valve volume is little, maintenance, easy to use does not need accessory, so use is comparatively general.But, existing anticorrosion solenoid valve has plenty of the manufacturing of the stainless steel of employing, its cost height, antiseptic property still can not be satisfactory, is moulded by fluorine in the employing cast iron manufacturing that has, the technology of valve is made complicated, easily breaks down or damages, and sealing position leakage easy to wear causes corrosion, even makes valve can not continue to use.
The purpose of this utility model provides at the bottom of a kind of cost, and simple in structure, antiseptic property is reliable, the anticorrosion solenoid valve of long service life.
Anticorrosion solenoid valve by valve seat, spool chamber loam cake, sealing clamp, spool tappet, be positioned at spool chamber top, and the tractive magnet and the spool that are fixed on the valve seat constitute, spool adopts corrosion resistant rubber or fluoroplastic to make.Spool tappet termination is inlayed and is wrapped in the valve core, and spool is fixedly connected on the spool tappet.Spool top and be positioned at spool chamber have one with the whole anticorrosion sheath of the volute that spring is arranged that is connected of spool, the spool tappet is positioned at the anticorrosion sheath of volute, and completely cuts off with spool chamber.The anticorrosion sheath upper end-hole of volute has the whole sealing eaves that connects, and loam cake and sealing clamp compress and seal eaves and the anticorrosion sheath of volute is fixed and spool chamber is sealed.The anticorrosion sheath of volute adopts corrosion resistant rubber or fluoroplastic manufacturing.
The spool of the anticorrosion solenoid valve that the utility model provides adopts corrosion resistant rubber or fluoroplastic manufacturing and has the whole volute protecting cover that connects that the spool tappet is sealed in rubber-like and adopts in the anticorrosion sheath that corrosion resistant rubber or fluoroplastic make, thereby improved the corrosion resistant performance of valve, prolonged the working life of valve.Anticorrosion sheath seals spool chamber by the sealing eaves, and it compresses to connect for the stationary connection has eliminated the sliding friction phenomenon between spool tappet and sealed letter in the past.Improve the sealing reliability of spool chamber, eliminated the corrosion that causes because of the leakage of carrying liquid.Valve relies on the rebounding force of spring and volute that spool is restored valve closing, thereby has simplified the structure of solenoid valve, thus simple in structure, reduced the cost of valve.
Accompanying drawing is a structural drawing of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
As shown in the figure, anticorrosion solenoid valve has a valve body (6) with snout cavity (7), outlet plenum (8), spool chamber (10), and spool chamber is suitable for reading by loam cake (3) and seal ring sealing.Loam cake spool tappet (11) passes the hole has sealing clamp (2) to seal by screw in compression.Spool (9) adopts corrosion resistant rubber or fluoroplastic manufacturing, and spool tappet termination is inlayed and is wrapped in the valve core.Spool tappet upper end connects with tractive magnet (1), the traction electromagnetism is fixed on the support (13), support, electromagnetism electricity sealing cover are in outer cover (12), there is the anticorrosion sheath of volute (4) lower end of helical spring (5) to be connected in employing corrosion resistant rubber or the fluoroplastic making with spool is whole, there is a sealing eaves (14) its upper end, and the sealing eaves is fixed by loam cake and pressing plate and the spool chamber sealing made and is positioned at anticorrosion sheath and has spool tappet and spool chamber to completely cut off.
Claims (1)
1, a kind of anticorrosion solenoid valve, include valve seat, the spool chamber loam cake, sealing clamp, the spool tappet, be positioned at spool chamber top and be fixed on tractive magnet on the valve seat, it is characterized in that spool adopts corrosion resistant rubber or fluoroplastic to make, spool tappet termination is inlayed to be wrapped in spool is fixedly connected on the spool tappet, spool top and be positioned at spool chamber have one be connected with spool integral body the anticorrosion sheath of helical spring volute arranged, the spool tappet is positioned at the anticorrosion sheath of volute and isolated with spool chamber, the anticorrosion sheath upper end-hole of volute has the whole sealing eaves that connects, loam cake and sealing clamp compress that the sealing eaves is fixed the anticorrosion sheath of volute and with spool chamber sealing, the anticorrosion sheath of volute adopts corrosion resistant rubber or fluoroplastic manufacturing.
