Description
Technical field
The utility model relates to a kind of solenoid electric valve and uses the air-conditioning refrigeration system of this solenoid electric valve, especially a kind of solenoid electric valve with pilot valve, the flow that in frequency converting air conditioner, is used to control compressor as the compressor solenoid valve, solenoid directional control valve is used in the flow direction that changes refrigerant in the air-conditioning, realization refrigeration in summer and the function conversion that heats winter are that example describes below with the solenoid directional control valve.
Background technique
The air-conditioning refrigeration system that uses solenoid directional control valve as shown in Figure 1, solenoid directional control valve is made up of electromagnetic coil 1, pilot valve 2, main valve 3 three parts, its structure and working principle are described below:
Main valve comprises a columnar valve body 31, the entrance sleeve D (being the zone of high pressure) that is connected with compressor outlet (relief opening) is arranged on it, the discharge connection S (being low pressure area) that is connected with suction port of compressor end (intakeport), the conduit E that is connected with indoor heat converter, the conduit C that is connected with outdoor heat converter, there are end cap 33 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 34, valve seat and the slide block kinematic pair that partners, piston and valve body are then formed another to kinematic pair, be separated into left chamber's (E side) that the position can change by piston, main valve inner chamber (301), right chamber (C side), piston then leans on shelves with the end cap face in valve body as the location, in the valve pocket structure of valve body of main valve and end cap composition, connection e is arranged, c joint capillaceous, be to drive slide block in the stroke that end face limited of a pair of two end caps of piston in valve body that connect by connecting rod to slide, so that realize that by the mobile displacement of slide block E/C takes over the commutation of inner fluid.
Pilot valve comprises sleeve pipe 28 "; its right-hand member is welded with end socket 21; form pilot valve inner chamber (201); the inner chamber left side is welded with little valve seat 29; have four step through-holes on the little valve seat; be welded with capillary tube d/e/s/c on the through hole respectively, capillary tube d and main valve D take over, capillary tube e and chamber, main valve left side valve body, capillary tube s and S take over, capillary tube c is connected respectively with the right chamber of main valve valve body, therefore the pilot valve inner chamber is the zone of high pressure, and s is a low pressure area, inner chamber has the core iron 24 that can horizontally slip and suppresses returning spring 23 in its hole, be connected as a single entity by riveted joint in addition, trailing frame 25 and the spring sheet 26 of riveted fixing in the core iron hole together then, trailing frame has perforate, the sliding bowl 27 that the bottom has shrinkage pool promptly is inlaid in this hole, spring sheet 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, and therefore sliding bowl is bearing the difference force that produces therefrom, and the sealing of kinematic pair is mainly realized by this difference force.
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 and s capillary tube, c communicates respectively with the d capillary tube, 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 to communicate, and this moment, the refrigeration agent circulation path of internal system was: compressor discharge pressurized gas → D adapter → main valve inner chamber → C adapter → outdoor heat converter → throttle element → indoor heat converter → E adapter → S 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 is communicated respectively with the d capillary tube with s capillary tube, e.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 → main valve inner chamber → E adapter → indoor heat converter → throttle element → outdoor heat converter → C adapter → S adapter → compressor air suction mouth heats working state so system is in.
Realize the commutation of main valve as mentioned above by the commutation of pilot valve, and by the switching of main valve to pipeline, just 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 pilot valve structure of prior art, shown in Figure 1A and Figure 1B, four capillary tube d/e/s/c all are welded on four step through-holes of little valve seat of pilot valve inner chamber, capillary tube (d) end that wherein connects main valve inner chamber and pilot valve inner chamber is inserted into the open pore 37 that main valve D takes over, and " the interior adapter with D is welded to connect; this structure can cause the pilot valve complex structure; operations such as little valve seat part processing and pilot valve welding assembly are had relatively high expectations, and also is unfavorable for pilot valve design of miniization and the use that reduces material resources.
