Abstract
The utility model relates to a permanent magnet directional valve. An upper valve seat is fixedly connected with an upper valve body, and a lower valve seat is fixedly connected with a lower valve body, each the upper valve seat and the upper valve body, and the lower valve seat and the lower valve body has a sealed air chamber therebetween. The inner wall of a shell cover to connect the upper and the lower valve bodies is fixed with an upper and a lower stator cores, and the upper and the lower stator cores have external stator coils. The center holes of the upper and the lower stator cores have a sliding fit with a magnetic control valve stem, and the upper and the lower stator cores form an activity cavity therebetween. A permanent magnet mover fixed to the magnetic control valve stem is positioned in the activity cavity, and the two ends of the magnetic control valve stem are fixed with valve clacks which are corresponding to the position of a stomata of the air chamber, and the side wall of the air chamber is communicated with an air outlet. The utility model uses the permanent magnet mover, the magnetic control valve stem and the valve clack, and therefore the valve has an automatic reversing function, and has the advantages of simple magnetic control mechanism, convenient manufacturing technology, low cost, and long service life.
Description
Affiliated field: the utility model relates to a kind of valve, particularly a kind of permanent magnetism selector valve.
Background technique: existing electromagnetic switch valve mechanism complexity, weight is big, quick abrasion, working life is short, and the prior art solenoid directional control valve mainly is made up of valve seat, iron core, valve body, coil, spring etc.Form magnetic field behind the coil electricity, produce magnetic force, iron core is picked up, secondary valve is opened, gas is depressed piston by aperture, valve commutation, and behind the failure of current, magnetic force hour, iron core compresses downwards with worried envelope and closes, and secondary valve piston is pushed to rapidly under the commutation spring action, and valve is closed.This valve process structure complexity, and the long-term energising of coil easily burns, and energy consumption is big.
Summary of the invention: the purpose of this utility model provides a kind of simple in structure, permanent magnetism selector valve that cost of production is low, esy to use, safe and reliable.The purpose of this utility model realizes by following structure: the utility model is a kind of permanent magnetism selector valve, upper valve base is fixedlyed connected with upper valve body, lower valve base is fixed on down on the valve body, on, lower valve base and upper valve body, each sealing forms an air chamber between the following valve body, in the connection, fixing on the clamshell inwall of following valve body and going up stator iron core and following stator iron core, last stator iron core and following stator iron core have stator coil outward, the magnetic control valve rod is being slidingly matched in last stator iron core and the following stator iron core center hole, form a movable chamber between last stator iron core and the following stator iron core, permanent magnetism mover fixing on the magnetic control valve rod is positioned at movable chamber, flap is being fixed at magnetic control valve rod two ends, flap is corresponding with the pore position of air chamber, and gas chamber sidewall is communicated with air outlet hole.The utility model is a kind of permanent magnetism selector valve, working principle of the present utility model: when electromagnetic stator coil forward energising up and down, upper and lower electromagnetic stator iron core is set up forward magnetic field, promote flap that the permanent magnet mover drives magnetic control valve rod, the valve rod two ends fast moving that makes progress, by permanent magnet mover and last electromagnetism stator iron core adhesive location, the lower valve base inlet hole is opened, annular cavity is closed, close the upper valve base inlet hole simultaneously, open the annular cavity on the upper valve base, the outlet air pressure on the valve body is discharged by exhaust port through annular cavity.When the electromagnetic stator coil is oppositely switched on, upper and lower electromagnetic stator iron core is set up the opposing magnetic field, promoting the permanent magnet mover moves down fast, inhale and the location by permanent magnet mover and following electromagnetic stator iron core, inlet hole on the upper valve base is opened, closed the annular cavity on the upper valve body, close the inlet hole on the lower valve base simultaneously, open down the annular cavity on the valve body, upper valve body upper outlet air pressure is got rid of by exhaust port through annular cavity.The utility model is owing to adopt the permanent magnet mover, and magnetic control valve rod flap makes this valve automatic reverse, and magnetic control mechanism is simple, and manufacturing process is easy, and cost of production is low, and is safe and reliable, long service life.
