Background technique
The structural principle of existing solenoid valve scheme is made up of electromagnetic coil, pilot valve, main valve three parts as shown in Figure 1, and its structure and working principle are described below:
Main valve comprises a columnar valve body 31, the vent connection D (being the zone of high pressure) that is connected with exhaust outlet of compressor is arranged on it, the air-breathing adapter S (being low pressure area) that is connected with the compressor air suction mouth, the adapter E that is connected with indoor heat converter, the adapter C that is connected with outdoor heat converter, there are end cap 34 sealing at the valve body two ends, interior welds has valve seat 36, slide block 35 that also useful connecting rod 32 fuses and pair of pistons 33, valve seat and the slide block kinematic pair that partners, piston and valve body are then formed another to kinematic pair, by piston the main valve inner chamber are separated into a left side (E side), in, right (C side) three chambers.
Pilot valve comprises circular casing 26, its left end is welded with little valve body 24, right-hand member is welded with end socket 29, little valve body upside is welded with main valve D and takes over the capillary tube d (so the pilot valve inner chamber is the zone of high pressure) that is connected, be welded with little valve seat 21 in the lower-side hole, have three step through-holes on the little valve seat, and part on the right side according to left-hand and not to be welded with and the main valve left end cap, S takes over the capillary tube e/s/c (so s is a low pressure area) that is connected with right end cap, cannula cavity has the core iron 27 that can horizontally slip and suppresses returning spring 28 in its hole, be connected as a single entity by rivet in addition, trailing frame 22 and the reed 25 of riveted fixing in the core iron hole together then, the trailing frame left end has perforate, the sliding bowl 23 that the bottom has shrinkage pool promptly is inlaid in this hole, reed then roof pressure on the top of sliding bowl, it is close on the little valve base surface sliding bowl lower end surface, sliding bowl can slide on little valve base surface with core iron/trailing frame assembly, sliding bowl has been formed a kinematic pair with little valve seat, its inner chamber (being capillary tube s) is a low pressure area, and its back (being the pilot valve inner chamber) is the zone of high pressure, therefore sliding bowl is bearing the difference force that produces therefrom, and the sealing of kinematic pair is mainly realized by this difference force.
Electromagnetic coil comprises the magnet case 14 that is encapsulated in the winding 12 on the skeleton and is positioned at the support of the whole electromagnetic coil of conduct outside the described insulation coating 15 by insulation coating 15, outwards draw leaded terminal 16 from described winding 12, described skeleton 11 has endoporus 11a; Electromagnetic coil is by corresponding and fastening by screw with the sphere of activities of core iron 27 on the circular casing 26 of endoporus 11a being installed being sleeved on pilot valve.
When air-conditioning needs refrigerating operaton, the electromagnetic coil no electric circuit, under the effect of returning spring, core iron drives sliding bowl and moves to left together, thereby make e/s, the c/d capillary tube communicates respectively, because taking over, S is low pressure area, so the gas in chamber, a main valve left side passes through e, s capillary tube and sliding bowl and flow into low pressure area, therefore left chamber becomes low pressure area, and the right chamber of main valve is owing to there be replenishing from c high pressure air capillaceous, thereby become the zone of high pressure, so between the chamber, the left and right sides of main valve, just formed a pressure difference, and therefore slide block and piston have been pushed to left side, make E, S takes over and communicates, D, C takes over and communicates, and this moment, the refrigeration agent circulation path of internal system was: pressurized gas → D adapter → valve body → C adapter → outdoor heat converter → throttle element → indoor heat converter → E adapter → slide block → S that compressor is discharged take over → is sucked by compressor then, so system is in the refrigeration work state.
When air-conditioning needed heating operation, electromagnetic coil is energising just, and under the effect of coil electromagnetic force, core iron overcomes the active force of returning spring and drives sliding bowl and move to right together, and c/s, e/d capillary tube are communicated respectively.As mentioned above, the right chamber of main valve just becomes low pressure area, left chamber then becomes the zone of high pressure, therefore slide block and piston just have been pushed to the right side, make C, and S takes over and communicates, D, E takes over and communicates, and the refrigeration agent circulation path of this moment is: exhaust outlet of compressor → D adapter → valve body → E adapter → indoor heat converter → throttle element → outdoor heat converter → C adapter → slide block → S adapter → compressor air suction mouth heats working state so system is in.
As mentioned above, just can realize the commutation of main valve by the acting in conjunction of electromagnetic coil and pilot valve, and switch the flow direction of refrigeration working medium by the commutation of main valve, make indoor heat converter become the condenser of the state that heats from the vaporizer of refrigerating state, outdoor heat converter has then become vaporizer from condenser, thus the purpose of the dual-use that makes air-conditioning realize freezing summer to heat winter.
The heat pump air conditioner solenoid valve of said structure, core iron overcome the active force of returning spring and drive the active force that sliding bowl moves to right together derive from the electromagnetic force that electromagnetic coil produces under "on" position.Therefore, the performance of electromagnetic coil counts for much to the overall performance of solenoid valve.
Yet, the electromagnetic coil of existing scheme is when energising, the flux path bottleneck 17 at its two ends (being places, magnetic conduction sleeve pipe two ends) is the magnetic flux dead angle, magnetic flux area little (seeing magnetic line of force c1 shown in Figure 6 for details), magnetic resistance is big, magnetic force loss is big, require operating voltage in less wave range (operating voltage range of existing coil voltage rating 85% to 110% between) can proper functioning; And, because the electromagnetic force loss after the energising of the electromagnetic coil of existing scheme is bigger, the heat that produces during energising is difficult for distributing, easily cause coil temperature rising phenomenon thus, influence electromagnetic coil usability (" usability " comprises temperature rise and the reliable in action performance when estimating electromagnetic coil with the supporting use of solenoid valve) and life-span.
