Background technique
Electromagnetism four-way change-over valve with existing structure describes below.The profile of the electromagnetism four-way change-over valve of existing structure is made up of electromagnetic coil 1, pilot valve 2, main valve 3 parts as shown in Figure 1.
The electromagnetism four-way change-over valve internal structure of this heat pump-type idle call is made up of electromagnetic coil 1, pilot valve 2, main valve 3 parts as shown in Figure 3.Its structure and working principle are described below:
Main valve comprises a columnar valve body 3.1, 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 3.3 sealing at the valve body two ends, interior welds has valve seat 3.6, also have the slide block 3.5 and the pair of pistons 3.4 that drive with connecting rod 3.2, 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 is separated into the left side (E side) that the position can change, in, right (C side) three chambers, piston then leans on shelves with the end face of the end cap in valve body as the location, 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 connected by connecting rod to slide, the mobile displacement by slide block realizes that each takes over the commutation of inner fluid.
Pilot valve comprises the semi-enclosed sleeve pipe 2.8 of pen cap shape, the right-hand member of its charged magnetic coil is welded with end socket 2.1, the inner chamber left side is welded with little valve seat 2.9, have four step through-holes (four step through-holes also can be cross arrangement or rounded arrangement) 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, the S of capillary tube s and main valve takes over, be connected with the right chamber of main valve with capillary tube c, therefore the pilot valve inner chamber is the zone of high pressure, and s is a low pressure area, cannula cavity has the core iron 2.4 that can horizontally slip and suppresses returning spring 2.3 in its hole, be connected as a single entity by riveted joint in addition, trailing frame 2.5 and the spring sheet 2.6 of riveted fixing in the core iron hole together then, the trailing frame left end has perforate, the sliding bowl 2.7 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, 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 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, and this moment, system was 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 → 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.
Electromagnetic coil energising when aforesaid four-way electromagnetic reversing valve also can be refrigeration, and electromagnetic coil outage during heating operation, just two of four-way electromagnetic reversing valve are taken over to exchange when E, C are connected with system and get final product, other structure and working principle are all same as above, repeat no more here.
The electromagnetism four-way change-over valve of this heat pump-type idle call, its main valve and pilot valve to be connected situation as follows: wherein be welded with shaped as frame upper bracket 4 on the pilot valve 2, be welded with shaped as frame lower support frame 5 on the main valve 3, pilot valve 2 is by upper bracket 4 is inserted on the lower support frame 5 with being connected of main valve 3, make, the side of lower support frame contacts, make by spot welding (spot welding place 5.1) then, lower support frame fuses, thereby pilot valve 2 is fixed on the main valve 3, for the linkage structure that makes pilot valve and main valve clear, so omitted four capillary tubies that are connected with main valve of pilot valve among Fig. 1, and this partial structure and this patent do not have dependency relation.
The electromagnetism four-way change-over valve of said structure all is welded with frame support on main valve and the pilot valve, realize being connected of main valve and pilot valve by the connection between two supports (part), the employed material of this kind structure is also just more, amount of finish is also bigger, and complex process also causes the increase of manufacture cost thus; And have more attachment security hidden danger because tie point, and can be given a shock as solenoid valve in use, these vibrations cause the spot welding of upper and lower support side touching position to be ftractureed easily.
