Description
Technical field
The present invention relates to the solenoid valve field, particularly a kind of DC bistable solenoid valve, as be used for the DC bistable solenoid valve of refrigeration technology field.
Background technique
Solenoid valve is the industry equipment with Electromagnetic Control, is used in direction, flow, speed and other the parameter of adjusting medium in the industrial control system.Solenoid valve is to control with the effect of electromagnetism, thereby realizes the control of expection.Solenoid valve has a variety of, and different solenoid valves plays a role at the diverse location of control system.
Solenoid valve can be divided into from using on the power supply: alternating current electromagnetic valve, DC electromagnetic valve, bistable electromagnetic valve or the like.General solenoid valve is formed by valve body parts and coil component.Below be that example is introduced the prior art content with the bistable electromagnetic four-way change-over valve.
Please refer to Fig. 1, Fig. 2, Fig. 3.Wherein Fig. 1 is the bistable electromagnetic valve system architecture schematic representation of prior art; Fig. 2 is the solenoid controlled circuit diagram of prior art; Fig. 3 is the electromagnetic coil fundamental diagram of prior art.
The bistable electromagnetic four-way change-over valve, form by electromagnetic coil 10, pilot valve 20, main valve 30 three parts, wherein, pilot valve 20 comprises circular casing 200, core assembly and some other component, core assembly comprises end socket 204 and core iron 208, the right-hand member of circular casing 200 is welded with end socket 204, and sleeve pipe 200 inner chambers have the core iron 208 that can horizontally slip and suppress returning spring 203 in core iron 208 spring eyes 209.Electromagnetic coil 10 comprises coil component 1022 and magnet case 1021, and its inside also is provided with permanent magnet 103.Electromagnetic coil 10 is set in the periphery of circular casing 200, and fixes with end socket 204 by set screw 202.
When the SW1 switch connection, the SW2 switch is got to ON, and electromagnetic coil 10 feeds forward currents at this moment, and the magnetic field that it produced is consistent with the magnetic direction that permanent magnet 103 produces, and as shown in Figure 3, wherein a is the magnetic line of force of permanent magnet; The coil magnetic line of force is b (solid line), its direction is identical with permanent magnet magnetic line of force direction, the electromagnetic force that electromagnetic coil 10 is produced overcomes the spring force of returning spring 210 with the magnetic force of permanent magnet 103, core iron 208 is moved to right (by direction as shown), with end socket 204 adhesives.At this moment, sliding bowl 205 moves to right with core iron 208, capillary tube s/c is connected, thereby the slide block 301 that drives main valve 30 moves right, and makes main valve take over S/C and is connected.After core iron 208 and end socket 204 adhesives, the SW1 switch disconnects, electromagnetic coil 10 outages, and electromagnetic force disappears, and this moment, the magnetic force spring force that overcomes returning spring 203 of permanent magnet 103 made core iron 208 and end socket 204 keep attracting states.
When the SW1 switch connection, the SW2 switch is got to OFF, and electromagnetic coil 10 feeds back currents at this moment, and at this moment, a is the permanent magnet magnetic line of force; The coil magnetic line of force is c (dotted line), and its direction is opposite with permanent magnetic line direction.The electromagnetic force that it produced overcomes the magnetic force of permanent magnet with spring force, make core iron 208 move to left (by direction as shown) reset.At this moment, sliding bowl 205 moves to left with core iron 208, capillary tube e/s is connected, thereby the slide block 301 that drives main valve 30 is moved to the left, and makes main valve take over E/S and is connected.After core iron 208 resetted, the SW1 switch disconnected, electromagnetic coil 10 outages, and electromagnetic force disappears, and the magnetic force that rely on spring force to overcome permanent magnet 103 this moment makes core iron hold reset state.
As seen, the bistable electromagnetic valve of prior art is the conversion moment between two kinds of states just to give electromagnetic coil 10 energisings, i.e. outage after converting.When core iron and end socket are in attracting state, utilize the attraction force of permanent magnet to make end socket end face and core iron end face overcome spring force maintenance applying after the outage.When core iron resetted, the magnetic force that utilizes spring force to overcome permanent magnet after the outage made core iron hold reset state.
