Description

Magnetic driving valve

The utility model relates to the improvement of Self controlling valve, especially a kind of Magnetic driving valve, and it belongs to the unit controls Element Technology field in the automatic control flows system.

In the prior art, in gas pipeline or water supply pipe, often use electric control valve.This valve mostly is solenoid valve.It is that the magnetic force that utilizes electromagnetic coil to produce removes the driven valve core bar.This valve often takes place: excessive because of the resistance of working fluid, and consumed power increases, and noise is also big.This valve must keep heavy current under opening or closing operating state, the ability execution, and this just causes the big drawback of energy consumption.Also have a kind of mortor operated valve, it utilizes gear engagement control spool.But because gear engagement is slow in one's movements, the switching time of spool is longer, is unfavorable for rapid automatic control.And it is loosening to use this valve that gear engagement can take place for a long time, influences the normal unlatching of spool or closes.

The purpose of this utility model is the defective that will overcome above-mentioned valve, designs a kind of low power consumption, the Magnetic driving valve that not influenced by AC outage.This valve will have rapid switch, is active in one's movements, and noise free does not have and leaks the characteristics that overall sealing performance is good.

Task of the present utility model has following technological scheme to finish, developed a kind of Magnetic driving valve, it comprises: main valve body, main valve plug, the valve gap of band passageway bridge, on the passageway bridge terminal aperture seat of valve gap housing, be provided with guide's spool, above this spool magnetic switch is housed, the permanent magnet blocks of this switch is controlled guide's spool and is opened and closed on this hole seat with contactless attraction force, constitute the keying of valve gap pilot valve, and then by the main valve plug in the differential pressure open-close main valve body.

Described magnetic switch, it is installed on the case seat board of guide's spool top, side at this seat board is equipped with the deceleration micro motor, the output axle head of this motor is equipped with eccentric wheel, this is taken turns and is inscribed within the rectangular guideway frame, this is installed in the guide-track groove, and rotate and in this rail groove, do reciprocating linear motion with the eccentric wheel in this, connect an intrinsic push-and-pull connecting rod on this a certain circumscribed long side plate, the other end of this bar connects solid on the magnetic cylinder sleeve, build-in has permanent magnet blocks in this cover, this cover and water magnet piece thereof reciprocatingly slide on antifreeze plate with this and this bar, and this antifreeze plate frame formerly on the trestle table of guide valve core, is provided with magnetic conductive hole admittedly on a side of antifreeze plate, this hole is just in time aimed on the magnetic conductive shell top of guide's spool, thereby constitutes the contactless attraction force of permanent magnet blocks to guide's spool.

Described guide's spool, it is by the trestle table that is fixed on the case seat board, be mounted in the magnetic conductive shell of the guide's spool in this, be sleeved on pellet shot from a slingshot iron core and push rod and pressure spring composition in this shell, wherein the following end shield of magnetic conductive shell is solid outside passageway bridge two stomidium seats, wherein the bottom build-in of pellet shot from a slingshot iron core has soft material, this material closely shutoff on the terminal aperture seat, push rod and pressure spring are housed in this iron core, this push rod upper end leans in the magnetic conductive shell top, this push rod lower end is pressed on this spring, constitute this iron core along ejector rob axis to the state that is slidingly matched that in magnetic conductive shell, moves up and down.

Also the eccentric wheel position transducer can be installed on described rectangular guideway frame and the guide-track groove thereof, this device is made up of the dry reed-pipe and the circuit thereof that are mounted in the permanent magnets on these long margin frame two ends and be located in the guide-track groove, wherein dry reed-pipe is separately positioned on the stage casing and the outer section of guide-track groove, be the maximum distance apart that eccentric wheel promotes this linear reciprocating motion, this distance has promptly constituted the keying two states to guide's spool.

Magnetic driving valve advantage of the present utility model is: owing on the passageway bridge terminal aperture seat of valve gap guide's spool and magnetic switch thereof are set, controlling guide's spool by the permanent magnet blocks of this switch with contactless attraction force opens and closes on this hole seat, constitute the keying of valve gap pilot valve, and then cause the inside and outside fluid pressure differential of main valve plug, main flow pressure is dashed open main valve plug, or make guide's valve pocket fluid stopping pressure close main valve plug with addition of the main valve plug spring pressure, realize the main valve plug switching motion of main valve body, and it is active in one's movements rapidly.Because designed magnetic switch employing deceleration micro motor for driving eccentric wheel and rectangular guideway frame make this linear reciprocating motion in guide-track groove, and then also do reciprocating linear motion by push-and-pull connecting rod drive magnetic cylinder sleeve and permanent magnet blocks thereof.This permanent magnet blocks can be carried out contactless attraction to guide's spool by the magnetic conductive hole on antifreeze plate one side, and then breakdown guide spool, guide's valve pocket inner fluid is flowed, and the fluid pressure differential that promptly be created on the main valve plug diaphragm this moment forces this diaphragm to be upspring, the conducting of main valve body cavity.So simultaneously, owing to be located at eccentric wheel position transducer---permanent magnets and dry reed-pipe on rectangular guideway frame and the guide-track groove, just in time section is met outside guide-track groove, dry reed-pipe conducting under the permanent magnets effect, and then give control system one signal by circuit, and being about to micro motor and stopping operating, eccentric wheel is in micro motor output shaft outside maximum distance apart, guide's spool is in the state of being attracted, and main valve body also is in normally open.No longer need electric power this moment, can keep normally open.When needs were closed main valve body, control system was sent and is started the micro motor signal, and micro motor rotating band movable eccentric wheel rotates and promotes the rectangular guideway frame and reciprocatingly slides, and then drove magnetic cylinder sleeve and permanent magnet blocks slip thereof.When permanent magnet blocks is pushed away the magnetic conductive hole of pilot valve core top, the pellet shot from a slingshot iron core of this spool no longer is subjected to magnetic attraction, and according to the pressure spring pressure in himself, to be with the pellet shot from a slingshot iron core shutoff of soft material bottom on the terminal aperture seat, pilot valve is at first closed, and then main valve plug in the pilot valve chamber fluid stopping pressure and the acting in conjunction of main valve plug spring pressure under close, main valve body is closed.So simultaneously, be located on the rectangular guideway frame permanent magnets just in time with the guide-track groove stage casing on dry reed-pipe meet, this reed switch conduction, and then give the another signal of control system by circuit, also micro motor is stopped operating, eccentric wheel is in the inboard maximum distance apart of micro motor output shaft, and guide's spool is not attracted, be in closed condition, main valve body also is in normally off.This magnetic switch, the integral sealing case, good seal performance is not subjected to external interference, the operation noise free, safe and reliable, the convection cell kind does not have selection, is suitable in the various fluid lines long service life.Because the deceleration micro motor that power source adopts chargeable cell to drive, its power consumption is little, and not influenced by AC outage.
