Abstract

The utility model provides an electromagnetic control device for a valve, relating to the technical field of a mechanical switch for the valve. The electromagnetic control device is fixed with an electromagnetic coil at one end of the machine body, the inner part of the machine body is provided with a stepped through hole in the coaxial direction of the electromagnetic coil, the inner part of the through hole is provided with a valve handle, and an annular permanent magnet is arranged outside the valve handle and at the upper part of the stepped through hole and is sleeved outside the valve handle as well as is fixedly connected with the valve handle. The electromagnetic control device has short electrifying time, makes the power of the coil with the same volume greater, can design a large flux electromagnetic valve, and solves the technical problem of the prior electromagnetic valve that the flux is small. The electromagnetic control device has a simple and reasonable structure, easy manufacture and convenient use, is particularly suitable for a large and mediums-sized membrane type two-position three-way valve, a large and mediums-sized piston type two-position three-way valve, a brake valve and a disconnecting valve, main valves of which need no offsetting spring.

Description

A kind of electromagnetic control apparatus of valve
Technical field
The utility model relates to a kind of mechanical switch technical field of valve.
Background technique
The control mechanism and the defective thereof of existing general gate valve and solenoid valve:
Existing general gate valve mainly contains manually and electronic two kinds.Hand sluice valve is mainly small-sized gate valve.Electric gate valve mostly is large and medium-sized gate valve greatly.The major defect of electric gate valve be electronic and mechanical transmission too complicated, volume is big, the cost height.And also more complicated of electric control equipment.
Existing general solenoid valve is made up of electromagnetic coil, static iron core, moving iron core, pilot valve, main valve etc.Be divided into normal close type solenoid valve and normal-open electromagnetic valve.Its major defect is solenoid valve when work of normal close type to need all the time that energising could keep often opening; Otherwise needing all the time during the work of the solenoid valve of open type, energising could keep normally closed.This has just proposed very high requirement to electromagnetic coil.Because the cause of long-time energising is so coil power can't be done greatly.Therefore existing calutron can only be applied on the valve of small-bore leading type.
The model utility content
The utility model purpose is little at the solenoid valve flux and a kind of electromagnetic control apparatus of valve design.
The utility model comprises a body, end at body fixedly installs electromagnetic coil, in body, be provided with and the homoaxial stepped through hole of electromagnetic coil, in this through hole, arrange a valve rod, outside valve rod, ring-like permanent magnet is set in the top of stepped through hole, described permanent magnet is nested with outside valve rod, and fixedlys connected with valve rod.
When electromagnetic coil feeds direct current, electromagnetic coil and permanent magnet produce active force and reaction force, drive the valve rod moving linearly, as connecting valve in the lower end of valve rod this moment, then can make valve relative movement in valve body, reach the purpose of unlatching or throttle down.
The utility model has effectively utilized the magnetic energy product and the coercivity of high strength magnetic material, utilize the coupling of soft iron on the electromagnetic coil and permanent magnet magnetic energy product and locate, current"on"time is short, only need the moment energising, therefore electromagnetic coil can feed bigger electric current, can make more powerfully with the coil of volume, can design the solenoid valve of big flux, solve the very little technical barrier of present solenoid valve flux.The utility model is simple and reasonable for structure, is easy to make, the convenient use.If on guide electromagnetic valve, use the utility model instead, then do not need Returnning spring, only need the moment energising, longer service life can make electromagnetic power bigger, and it is easier that spool starts.The existing drawback that normal-open electromagnetic valve can not be closed for a long time, the normal close type solenoid valve can not be opened for a long time will thoroughly be changed.The utility model also can be used as the direct control of some valvelets, and its structure is more simple.The utility model is specially adapted on big-and-middle-sized diaphragm type, piston type two-position three-way valve, gate valve, the stop valve, and main valve does not need to be provided with Returnning spring.
For further reduced volume, improve power of the present utility model, permanent magnet described in the utility model can be two groups, homopolarity is relatively axial arranged along valve rod, formed axial three polarity permanent magnets, and the height of described electromagnetic coil is two group permanent-magnet height overalls 2/3.
The utility model also can be on valve rod away from permanent magnet a fixedly connected upper valve core and a lower valve core, the bottom of described stepped through hole is provided with two sections step holes, described upper valve core and lower valve core are arranged in two sections step holes, and two five-way control valves are set on body.By two groups of spool moving linearlies on the electromagnetic field drive valve rod, reach the purpose that changes fluid passage, thereby control other and do powered device with fluid, for example distribution of hydraulic system, pneumatic system and control, and some make the control of the valve of power of fluid.
