Abstract

The utility model relates to a permanent-magnet air valve. A valve seat and a valve body are fixedly connected. The top part of the valve body connects by screw to a valve cover. The permanent-magnet air valve is characterized in that: a stator coil is fixed on a stator skeleton in the valve cover; a stator iron core is sheathed in the stator skeleton; a magnetic-control valve pole and a centre hole of the stator iron core are in sliding clearance fit. One end of the magnetic-control valve pole is arranged outside the valve body. The other end of the magnetic-control valve pole is arranged in an inner pressure chamber and is fixedly connected to a permanent-magnet mover valve clack. The two sealing surfaces, an upper one and a lower one, of the permanent-magnet mover valve clack are both provided with a seal gasket. The bottom of the permanent-magnet mover valve clack is toward an inner pressure hole. The inner pressure hole is arranged on a magnetic-control valve core. The inner pressure hole connects to a valve hole of an intake valve clack. The magnetic-control valve core is installed in an exhausting valve clack. The exhausting valve clack and the intake valve clack are fitted in slid. The permanent-magnet air valve adopts the permanent-magnet mover valve clack. A handheld magnetic-control valve pole makes the valve open or close automatically. The magnetic-control mechanism is simple with advanced draft technology, low production cost, long service life, safety and reliability.

Description

The permanent magnetism air valve

Affiliated field: the utility model relates to a kind of permanent magnetism air valve.

Background technique: existing electromagnetic air valve mechanism complexity, weight is big, quick abrasion, working life are short, the prior art electromagnetic air valve mainly is made up of valve seat, spool, valve body, coil, spring etc., form magnetic field behind the coil electricity, produce magnetic force, iron core is picked up, secondary valve is opened, and air is depressed piston by aperture, valve open, magnetic force disappears behind the supply disconnecton, iron core compresses downwards with worrying the envelope spring, closes secondary valve, and piston is under the effect of commutation spring, pushed to rapidly, valve is closed.This valve complex process, 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, and cost of production is low, and is easy to use, safe and reliable permanent magnetism air valve.The purpose of this utility model realizes by following structure: the utility model is a kind of permanent magnetism air valve, valve seat is fixedlyed connected with valve body, the valve body top valve gap that is threaded, fixed stator coils on the stator skeleton in the valve gap, stator iron core is sleeved in the stator skeleton, the magnetic control valve rod is that glade plane space cooperates with the stator iron core center hole, magnetic control valve rod one end is positioned at the valve body outside, the other end is positioned at presses chamber and is connected and fixed permanent magnetism mover flap, on the permanent magnetism mover flap, following two sealing surfaces all have sealing gasket, permanent magnetism mover flap bottom is facing to interior pressure hole, the interior hole of pressing is positioned on the magnetic control spool, and interior pressure hole is communicated with the valve opening of air inlet flap, and the magnetic control spool is installed in the exhaust flap, exhaust flap and valve body are slidingly matched, adopt seal membrane to link to each other between exhaust flap and the valve body, air inlet flap step plane has sealing gasket, and it is indoor that air inlet flap small end is positioned at outlet chamber, it is indoor that big end is positioned at air-inlet cavity, and outlet chamber connects exhaust port.The utility model is a kind of permanent magnetism air valve, valve seat is fixedlyed connected with valve body, respectively form an air chamber between valve seat and the valve body, valve gap and valve body link, at valve gap internal fixation stator skeleton, stator core, stator coil, the magnetic control valve rod that is being slidingly matched in the stator iron core center hole is being fixed permanent magnetism mover flap on the magnetic control valve rod, be positioned at active chamber.Air inlet flap and exhaust flap are connected in two air cavitys, are fixing the magnetic cavity spool on the exhaust flap, and chamber sidewall communicates with exhaust port.The utility model is a kind of permanent magnetism air valve, working principle of the present utility model: when when electromagnetic stator coil forward is switched on, the electromagnetic stator iron core is set up forward magnetic field, promote permanent magnetism mover flap and drive the magnetic control valve rod fast moving that makes progress and open magnetic control spool endoporus on the exhaust flap, locate the exhaust flap by permanent magnetism mover flap and the adhesive of electromagnetic stator iron core and under interior pressure effect, promote the air inlet flap and move down valve and be opened.Close the exhaust flap simultaneously.When the electromagnetic stator coil is oppositely switched on, the electromagnetic stator iron core is set up the opposing magnetic field, promoting permanent magnetism mover flap drive magnetic control valve rod moves down fast, close and press the hole in the magnetic control spool on the exhaust flap, by permanent magnetism mover flap and magnetic control spool adhesive location, interior pressure chamber pressure is discharged through the magnetic control valve lever clearance, the air inlet flap moves up under the suction pressure effect, valve is closed, and opens the exhaust flap simultaneously, and the chamber pressure of giving vent to anger is discharged through exhaust port.Can drive permanent magnetism mover flap by manual magnetic controlled valve rod when power supply interrupts suddenly in using, valve is risen the spare time automatically.The utility model is owing to adopt permanent magnetism mover flap and manual magnetic controlled valve rod that automatic the rising of valve closed, and the magnetic control mechanism advanced person formulates the technology advanced person, and cost of production is low, and is safe and reliable, long service life.
