Technical field
The utility model relates to the bistable electromagnetic valve that a kind of refrigeration refrigerator is used, the especially a kind of bistable state two-position three way magnetic valve that can control the refrigeration agent circulation path.
Background technique
In the prior art, the solenoid valve used of refrigeration refrigerator mainly is two-position three way magnetic valve and improved on its basis bistable state two-position three way magnetic valve.With regard to the structure of bistable electromagnetic valve, mainly include: field coil assembly, valve body parts, field coil are enclosed within to be opened up on the body component, and the mangetic core assembly in the diplopore assembly that valve body parts mainly is connected by valve gap, two ends, single hole assembly and the valve pocket.Above-described two-position three way magnetic valve has following shortcoming: 1 power consumption, solenoid valve are when work, and electromagnetic coil needs long-term energising, influence the capability of energy dissipation of refrigerator; 2 electromagnetic coils burn out easily, because the electromagnetic valve function of prior art realizes by spring, valve body is longer, must there be enough electromagnetic forces to overcome spring force work, and coil needs long-term energising, for cutting down the consumption of energy and controlling temperature rise, needs to adopt thinner enameled cable, under the influence of temperature rise and the high low temperature variation of working environment, the coil spoilage is higher; 3 action noises are big, though the solenoid valve of prior art has adopted the rubber buffer sheet to reduce the action noise at two ends of iron core, rubber material still belongs to the solid kind material, and because the Effect on Performance of rubber material own, the action noise fluctuations of generation is big.Though the bistable state two-position three way magnetic valve is having bigger improvement aspect energy consumption and the coil damage, because spool actuating mechanism and buffer structure are similar, equally move with two-position three way magnetic valve, its noise is still big and wave range is also bigger.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of energy consumption low, the action low noise bistable electromagnetic valve that noise is little and the noise fluctuations scope is little, it includes field coil assembly, valve body parts, field coil is enclosed within on the valve body parts, valve body parts includes the mangetic core assembly in diplopore assembly, single hole assembly and the valve pocket that valve pocket, two ends be connected, valve core inside two ends at mangetic core assembly respectively are provided with the caulking gum piece, be mounted with spring in the middle of it, and make between the two caulking gum pieces gapped.
The sealing surface separately of two caulking gum pieces leaves spacing with corresponding spool end in the described spool, and adjacent diplopore assembly of putting with spool end and single hole assembly all are processed with and stretch out the valve port of end face separately.
The valve port length of stretching out end face separately on described diplopore assembly and the single hole assembly is greater than the spacing of each self-corresponding caulking gum piece sealing surface with corresponding spool end.
The valve port length of stretching out end face separately on described diplopore assembly and the single hole assembly is greater than each self-corresponding caulking gum piece sealing surface and the spacing of corresponding spool end and the gap sum between the two caulking gum pieces.
The outer valve pocket of the also described spool of the utility model is provided with ring groove, is mounted with symmetry and opposite polarity two fan-shaped permanent-magnet steels in the groove.
The utility model compared with prior art, it is low to have energy consumption, the action noise little, the noise fluctuations scope is also little, stable working state, characteristics such as good reliability.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in accompanying drawing 1, the accompanying drawing 2, the utility model mainly includes field coil assembly 1, valve body parts 2, and field coil is enclosed within on the valve body parts 2.Valve body parts 2 includes the mangetic core assembly 6 in diplopore assembly 4, single hole assembly 5 and the valve pocket that valve pocket 3, valve pocket two ends be connected, and sees shown in the accompanying drawing 3.The described valve pocket 3 of the utility model is provided with ring groove 7, be mounted with in the groove symmetry and polarity in opposite directions two fan-shaped permanent magnetic steels 8 and constitute permanent magnet mechanism.Because being parallel to spool 6 in spool zone of action symmetry center is furnished with two fan-shaped permanent magnetic steels 8, magnet steel the two poles of the earth in opposite directions, it is identical to form field intensity at two ends, spool 6 action center along axial direction like this, the magnetic field that the magnetic line of force is just opposite, the theoretical center of spool zone of action is an equinoctial point, but spool can not just in time be in this equinoctial point in actual the use, spool one departs from equinoctial point, two opposite magnetic fields change to the force balance of magnet steel, spool moves to diplopore assembly valve port or single hole assembly valve port and contact along the stronger direction of active force, the valve port of fixed position blocks spool 6 and moves, and the effect of permanent magnet mechanism makes spool have auto-lock function in this position.Pulse by accompanying drawing 1 applies pulse signal to solenoid valve, the magnetic direction that field coil produces along axis from single hole assembly 5 to diplopore assembly 4, this magnetic field that periodically produces has been destroyed permanent magnet mechanism and has been produced the balance in magnetic field, make spool 6 positions be in diplopore assembly end, when changing the input pulse direction, i.e. the magnetic direction of the negative impulse field coil generation that input and accompanying drawing 1 are opposite is just opposite.Because the time of spool action is short, instantaneous impact force bumps spool 6 and diplopore assembly 4 or single hole assembly, easily produce bigger action noise, for reducing the action noise, the utility model is respectively to be provided with caulking gum piece 9 at the valve core inside two ends of mangetic core assembly 6, sees to be mounted with prefastening force spring 10 between the two shown in the accompanying drawing 4, and make and have gap L 3 between the two, this gap L 3 is displacement amounts that the arbitrary caulking gum piece of spool two ends moves in spool under external force.Spool and diplopore assembly match end with locked spacer 11 with caulking gum piece 9 and spring 10 rivetings in inside.The sealing surface separately of two caulking gum pieces leaves spacing L4 and L5 with corresponding spool end in described spool.Adjacent diplopore assembly of putting with spool end and single hole assembly 5 all are processed with and stretch out the valve port of end face separately, see shown in accompanying drawing 5, the accompanying drawing 6, and wherein diplopore assembly 4 stretches out the valve port length L 1 of end face greater than spacing L4 and gap L 3 sums; Single hole assembly 5 stretches out the valve port length L 2 of end face greater than spacing L5 and gap L 3 sums.Design margin does not contact spool all the time with single hole assembly end face with diplopore assembly end face in action simultaneously, impact force in the action is through repeatedly cushioning, be between valve port and caulking gum piece and the prefastening force spring, between the caulking gum piece, between caulking gum piece and the spool, reduced the noise that the spool action produces.
The utility model utilizes the characteristic distributions of spool zone of action symmetric magnetic field, spool all has auto-lock function two working positions, realize the action or the commutation of solenoid valve by positive back pulse, periodically apply the pulse control electromagnetic valve, reduce the energy consumption of solenoid valve and do not had temperature rise, improved reliability of products, reduced the organization plan of action noise in addition by valve inner, greatly reduced solenoid valve and move the sound level power noise of instantaneous generation.
