Abstract
A kind of permanent magnet electromagnetic valve, it includes valve body, and permanent magnet spool in valve body, spool both ends are fixed with left gasket and right gasket, and iron core is connected to valve body, and sealing ring is connected between valve body and iron core, and coil is wound on iron core, and iron cover is connected and fixed iron core and valve body；When the coil is energized, iron core generates the magnetic pole mutually repelled with permanent magnet spool, pushes spool to move left under repulsive force and seals valve port of valve body, the right valve port is opened；When disconnecting coil power, core magnetic pole disappears, and permanent magnet spool moves right under own magnetic force effect and seals iron core valve port, while left side valve port is opened.Invention removes the spring structures of common solenoid valve, keep electromagnetic valve structure simple, stablize, reliably.
Description
Technical field
The present invention relates to a kind of valve, specifically a kind of solenoid valve.
Background technique
Solenoid valve is to use the power on coil stimulating to generate electromagnetic force, drives valve core movement, to open or close valve, changes
The flow direction of fluid.Solenoid valve in the automatic control and long-range control of fluid using very extensive.In common electricity
In magnet valve, it is usually provided with antagonistic spring.Its structure is more complicated, and active force is small, and stability is poor, and the service life is short, holds in use
Easily break down.Especially strong in some corrosivity, inflammable, the electromagnetic valve structure applied in explosive equal fluids control is more multiple
It is miscellaneous.
Summary of the invention
The disadvantages of structure is complicated, and stability is poor, and active force is small, and the service life is short in order to fundamentally overcome conventional solenoid valve,
The present invention provides that a kind of structure is simple, and reliable and stable, the service life is long, using wider array of electromagnetic valve.
Present invention technical solution used for the above purpose is: a kind of permanent magnet electromagnetic valve, it includes valve body, valve body
Interior permanent magnet spool, permanent magnet spool both ends are fixed with left gasket and right gasket, and iron core is connected to valve body, sealing ring connection
Between valve body and iron core, coil is wound on iron core, iron cover is connected and fixed iron core and valve body；When the coil is energized, iron core generate with
The electromagnetic force that permanent magnet spool mutually repels pushes permanent magnet spool to move left and seals valve port of valve body, opens under repulsive force effect
The right iron core valve port；When disconnecting coil power, iron core electromagnetic force disappears, and permanent magnet spool moves right under own magnetic force effect
It is dynamic to seal iron core valve port, while left side valve port is opened.
The permanent magnet spool is made into using permanent-magnet material；Iron core, iron cover are made into using soft magnetic materials；Valve body, left sealing
Pad, right gasket are made into using non-magnetic material.
The left gasket salable valve port of valve body under magnetic force thrust；Right gasket salable iron core under magnetic force pulling force
Valve port.
The iron cover connection valve body and iron core play secured core and reinforce magnetism intensity.
The present invention is attractive to soft magnetic bodies using permanent magnet and the same characteristic repelled each other of magnetic pole is made by Switching Power Supply
Coil is powered and no power, and so that iron core is generated electromagnetic force becomes magnet and do not generate electromagnetic force as soft magnet core, realizes permanent magnetism
The reciprocating movement of body spool realizes the folding function of electromagnetic valve to realize the closing and opening to electromagnetism valve port.The present invention
The spring structure of conventional solenoid valve is eliminated, no longer as phase reciprocity law occurs in spring structure in magneticaction spool moving process
The phenomenon that power, improves reliability to improve the efficiency of active force, improves service life, simplifies structure, saved at
This.
Detailed description of the invention
Fig. 1 is the sectional view of permanent magnet electromagnetic valve of the invention.
Fig. 2 is the explosive view of permanent magnet electromagnetic valve of the invention.
Specific embodiment
As shown in Fig.1 and Fig.2, a kind of permanent magnet electromagnetic valve, it includes valve body 1, valve body to the structure of permanent magnet electromagnetic valve of the invention
Permanent magnet spool 2 in 1,2 both ends of permanent magnet spool fixed left gasket 3 and right gasket 4, iron core 5 is connected to valve body 1, close
Seal 6 is connected between valve body 1 and iron core 5, and coil 7 is wound on iron core 5, and iron cover 8 is connected and fixed iron core 5 and valve body 1；When coil 7
When energization, iron core 5, which is generated, repels electromagnetic force with 2 phase of permanent magnet spool, pushes permanent magnet spool 2 left in the case where repelling electromagnetic force
Mobile to seal 1 valve port of valve body, iron core 5 valve port in the right is opened；When disconnecting 7 power supply of coil, 5 electromagnetic force of iron core disappears, permanent magnet
Spool 2 moves right in the case where itself is to the magneticaction of iron core 5 seals 5 valve port of iron core, while valve body 1 valve port in the left side is opened, from
And realize the switching that valve port folding is realized by the switch of power supply.Invention removes the spring structures of conventional solenoid valve, utilize
Permanent magnet makes in spool moving process no longer as spring the attractive effect of soft magnetic bodies using magnetic force with the characteristic repelled each other
There is the phenomenon that mutual reaction force in structure, to improve the efficiency of active force, improves reliability, improves using the longevity
Life simplifies structure, has saved cost.
