Model utility content
The utility model improves existing direct-acting type two-bit triplet electromagnetic valve structure, reaches sealability and improves, the object that structure is simple, easy to process.
The technological scheme of the utility model technical solution problem is: the design proposal that the utility model adopts push rod and leading type to combine.Direct acting post rod type two-bit triplet solenoid valve, comprises valve body, valve rod, valve gap, spool and electromagnetic coil.Described valve body is three orthogonal crossing cross-bar-shapeds of cylindrical body, and be provided with valve port above, be arranged with medium entrance P1 and media outlet P2 in the valve body left and right sides, valve body front is provided with media outlet P3.Be equipped with medium channel in described medium entrance P1, media outlet P2 and media outlet P3, above described valve body, establish valve rod, in valve body and valve rod, establish spool; Valve rod peripheral hardware electromagnetic coil.Valve gap is established in described body base lower end surface, and described valve gap is the nut with inner chamber, is screwed in body base, is provided with push rod, self contering sealing gasket and Returnning spring between described valve gap and body base inner chamber.
Described valve rod is hollow cylindrical, and bottom is connected with nut and is screwed in above described valve port.
Described spool comprises dynamic iron core, static iron core and push rod, and described dynamic iron core is arranged in valve rod, and dynamic iron core is have internal channel and the tapered hollow cylinder in lower end, and taper outer race is provided with the pressure spring of falling turriform.Described static iron core is screwed in valve rod upper end; Described push rod is arranged on bottom body cavity, and push rod is that three posts add disk, and described three posts are connected with disk plane is vertical and puts in set three the dull and stereotyped apertures of body cavity.
The internal channel lower end of described dynamic iron core is embedded with rubber seal chock plug, and seals with body cavity medium passway and contact.
The utility model direct acting post rod type two-bit triplet solenoid valve, owing to adopting push rod and leading type to combine, becomes push rod direct-acting type by spool design, and push rod is designed to three posts adds disc-shape, can prevent push rod, is shifted in use and reduces its function.The design is skillfully constructed, and overcomes the problem that direct-acting type push rod is easily shifted preferably, not only increases solenoid valve using effect, and expands application area.
