Abstract
The utility model discloses an automatic control three-position three-way electromagnetic valve for a refrigerating system. A left electromagnetic coil and a right electromagnetic coil are installed on the exterior of a valve shell body. Iron yokes are sheathed outside the coils. A double-hole fixing valve core is arranged on one inner end of the valve shell body, a simple hole fixing valve core of which the tail is provided with a thread is arranged on the other end of the valve shell body. A slide core is arranged in the middle of the valve shell body. A valve nozzle and a spring are respectively arranged inside a left valve cavity and a right valve cavity. A force application spring and a rubber block used for blocking the valve nozzle are arranged inside a center hollow cavity of a slide valve core. The automatic control three-position three-way electromagnetic valve for a refrigerating system can realize automatic control, simultaneously, can transport refrigerating liquid towards one loop or two loops of the refrigerating system, and can flexibly realize the closing of one loop when required. The utility model has the advantages of high reliability and long service life of a compressor. The automatically controlled three-position three-way electromagnetic valve for a refrigerating system can sufficiently use the refrigerating capacity of the compressor.
Description
The utility model relates to a kind of refrigeration system and controls 3-position-3-way solenoid valve automatically.
At present, the solenoid valve that is used for refrigeration system control, it generally is two position three-way valve, can only be in process of refrigerastion to a loop wherein for coolant, when two-way needed to lower the temperature simultaneously, another loop can only be waited for and could begin refrigeration after last loop works finishes, prolonged the operating time of compressor, when temperature rise is very fast, might cause not left alone without help machine phenomenon, the life-span of lossy compression method machine.
The purpose of this utility model is to overcome the deficiency that above-mentioned existing two-position three way magnetic valve exists, realize that automatically control is to a refrigeration system loop or simultaneously to two loop transport coolants wherein and provide a kind of, and, when arbitrary loop temperature is reduced to when temperature required, can control automatically and close this loop, thereby make full use of compressor output, shorten the available machine time, the refrigeration system that prolongs compressor working life is controlled 3-position-3-way solenoid valve automatically.
The purpose of this utility model realizes by following measure: in the outside of a tubular shape valve shell, divide the left and right left and right electromagnetic coil that is provided with, put the iron yoke that is used for fixing coil and valve body at the coil overcoat.Left end is installed the diplopore fixed spool in the valve shell, and right-hand member is installed the screwed single hole fixed spool of afterbody, and the centre is provided with sliding valve core.The diplopore fixed spool wherein welds the refrigerant liquid intake channel on the hole, and welding refrigerant liquid outlet pipe on another hole, this outlet pipe are equipped with valve by chamber, a valve left side one end to be chewed.Welding one coolant outlet pipe on the single hole fixed spool, this pipe are equipped with valve by the right chamber of valve one end to be chewed.Be respectively arranged with spring between sliding valve core two ends and two fixed spools.Be provided with cavity in the sliding valve core, a spring is housed in the chamber, the two ends of this spring respectively are provided with a cylindrical body block rubber.
Accompanying drawing is this solenoid valve master sectional view.
Embodiment to this solenoid valve is described below in conjunction with accompanying drawing: valve shell 1 is cylindrical shape, left and right two coils 2 and 3 of being nested with of part outside it, and coil 2,3 is fixed in the rectangular box-like iron yoke 4 of two square holes.Left end is installed diplopore fixed spool 5 in the valve shell 1, and right-hand member is installed the screwed single hole fixed spool 6 of afterbody, and the centre is provided with sliding valve core 7, spool 5,6 and valve casing preparation, add weldering after the assembling, the outer end of spool 6 is threaded part and passes iron yoke 4 usefulness nuts and fix.Diplopore fixed spool 5 wherein welds liquid inlet pipe 8 on the hole, and coolant pipe thus enters in the valve, and another hole connects drain pipe 9, and the right-hand member of pipe 9 connects a valve by chamber, a valve left side one end and chews 10.Welding one drain pipe 11 on the single hole fixed spool 6, the left end of this pipe chews 12 by the right chamber of valve one edge joint, one valve.
When two refrigerating circuits need to lower the temperature simultaneously, (two coil no electric circuits this moment) coolant enters left chamber in the valve by liquid inlet pipe 8, a part by the valve on the spool 5 chew 10 flow to the footpath drain pipe 9 flow out to refrigerating circuit one, another part is by the right chamber of the guiding gutter flow valves on valve internal clearance and the sliding valve core 7, valve on fixed spool 6 is chewed 12 and is flowed to drain pipe 11 to refrigerating circuit two, reaches the purpose of cooling simultaneously.
If loop one temperature drops to when temperature required, electromagnetic coil 2 energisings, produce magnetic field, make the spring 13 between sliding valve core 7 extruding itself and the fixed spool 5, be moved to the left, when spool 7 with after spool 5 contacts, valve is chewed 10 and is just in time entered in the hole at center, spool 7 left side, contacts with the block rubber 17 that is provided with in spool 7 cavitys, and by spring 15 application of forces that are provided with in spool 7 cavitys, make valve chew 10 sealings, reach the purpose of closing loop circuit one.
Otherwise loop two temperature drop to when temperature required, coil 3 energisings, and the elastic force that spool 7 overcomes spring 14 moves to spool 6, chews 12 by block rubber 16 sealings 1 valve, reaches the purpose of closing 1 loop two.
This solenoid valve is by the test of sample test-run a machine, adopt two 222 liters of double temperature double control refrigerators, continue to use former two-position three way magnetic valve for one, another installs the utility model solenoid valve, under the same conditions, started shooting simultaneously 40 minutes, and recorded the mean temperature of identical point in the refrigerator cold-storage, refrigerating chamber, the refrigerator that the utility model 3-position-3-way solenoid valve is housed is than low 12.8 ℃ of the refrigerator temperature of original-pack solenoid valve.
