Abstract
The utility model provides a bistable pulse electromagnetic valve of a refrigerator with reliable and sensitive reversing. The electromagnetic valve comprises a valve body, a valve core, a permanent magnet and a coil. A single-passage valve seat is arranged at one end of the valve body, and a double-passage valve seat is arranged at the other end of the valve body. The double-passage valve seat is provided with a first passage and a second passage. The outlet of the first passage at the inner end of the double-passage valve seat is arranged in the middle of the inner end of the double-passage valve seat. The outlet of the second passage at the inner end of the double-passage valve seat is arranged outside the outlet of the first passage at the inner end of the double-passage valve seat. The valve core is arranged in the valve body which is arranged between the single-passage valve seat and the double-passage valve seat, and can move to close the outlet of the inner end of the single-passage valve seat and the outlet of the first passage at the inner end of the double-passage valve seat. The permanent magnet is arranged in the middle of the exterior of the valve body. As the technical scheme is adopted, when a refrigerant flows into the valve body from the second passage, and the refrigerant needs to bypass a step and then cannot directly have impact on the valve core, the impact by the external force can be reduced during the reversing of the valve core, and the reversing reliability and the sensitivity are enhanced.
Description
Technical field
The utility model relates to a kind of two-bit triplet refrigerator solenoid valve, is used for refrigerant is transported in requisition for the storeroom of refrigeration.
Background technique
Bistable state refrigerator impulse electromagnetic valve is a kind of need change the on off state of solenoid valve by the positive-negative polarity of control impuls a refrigerator part, when sending electrical pulse, the driving spool overcomes permanent magnetism power and produces mobile, reach switching purposes, the electrical pulse commutation finishes the back and keeps state by the permanent magnet on the valve body, and it is therefore energy-conservation that the electric current that need not continue is kept state.Present above-mentioned solenoid valve directly impacts spool when refrigeration agent flows into valve body, can influence the reliability and the sensitivity of commutation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of reliable sensitive bistable state pulse refrigerator solenoid valve that commutates.For this reason, the utility model is by the following technical solutions: comprise valve body, spool, permanent magnet and coil, be provided with the single channel valve seat the other end at an end of valve body and be provided with the Twin channel valve seat, described Twin channel valve seat has first passage and second channel, the outlet of first passage in Twin channel valve seat the inner is in the centre of Twin channel valve seat the inner, the outlet of second channel in Twin channel valve seat the inner is in first passage outside the side of the outlet of Twin channel valve seat the inner, and spool is in the valve body between single channel valve seat and the Twin channel valve seat and is movable and close the outlet in Twin channel valve seat the inner of the inner outlet of single channel valve seat or described first passage; Permanent magnet is in the outer valve body intermediate portion of valve body, and described coil wraps in outside the valve body, and described Twin channel valve seat side surface has step at second channel before the outlet of Twin channel valve seat the inner.Owing to adopt the technical solution of the utility model, when described second channel flows into valve body, must walk around step when refrigeration agent and directly not impact spool, reduce the impact of external force when being beneficial to the spool commutation, improve the reliability and the sensitivity of commutation.

Embodiment
With reference to accompanying drawing.The utility model comprises valve body 1, spool 4, permanent magnet 6 and coil 5, is provided with single channel valve seat 2 the other ends at an end of valve body and is provided with Twin channel valve seat 3, and described Twin channel valve seat has first passage 31 and second channel 32.First passage 31 and second channel 32 have interface respectively, and the interface A10 of first passage 31 meets refrigeration agent outlet pipe A1, and the interface B1 of first passage 31 meets refrigeration agent intake channel B; Single channel valve seat 2 has interface A20, meets refrigeration agent outlet pipe A2.
The outlet 310 of first passage in Twin channel valve seat the inner is in the centre of Twin channel valve seat the inner, the outlet 320 of second channel in Twin channel valve seat the inner is in first passage outside the side of the outlet 310 of Twin channel valve seat the inner, and spool 4 is in the valve body between single channel valve seat 2 and the Twin channel valve seat 3 and is movable and close the outlet 20 in Twin channel valve seat the inner of the inner outlet 310 of single channel valve seat or described first passage; Permanent magnet 6 is in the outer valve body intermediate portion of valve body, and described coil wraps in outside the valve body, and described Twin channel valve seat side surface has step 321 at second channel before the outlet of Twin channel valve seat the inner.Shown in arrow in Fig. 2 and 3 and rear elongation line thereof, two kinds of flow of refrigerant routes provided by the utility model, when described second channel flows into valve body, must walk around step and directly not impact spool, like this, the external impacts that has been subjected to when having reduced the spool commutation improves the reliability and the sensitivity that commutate.When implementing, described step 321 can be the ring-shaped step around end side surface in the described Twin channel valve seat.
The inner of described single channel valve seat exports 20 and protrudes in the middle of the inner of described single channel valve seat, and first passage is in the middle of outlet 310 protrusions the inner at described Twin channel valve seat of Twin channel valve seat the inner; Described spool comprises rubber inner core 41, can be by the metal shell 42 of attraction, back-up ring 43, described metal shell has bottom 420, described bottom is provided with hole 421, described back-up ring 43 embeds in the top 422 of metal shell, the hole 421 of described metal shell bottom and the hole 430 on the back-up ring are stretched into and are sealed and matched with rubber inner core 41 in the outlet 310 of Twin channel valve seat the inner for the inner outlet 20 of single channel valve seat and first passage respectively, like this, can reduce the gap between metal shell and single channel valve seat body and the Twin channel valve seat body respectively, to increase the attraction force of commutation rear valve base to spool; Simultaneously, described outlet directly contacts with rubber inner core, also can further improve sealing under the prerequisite in life-span satisfying.
The peripheral shape of described spool 4 is the square of foursquare arc transition, like this, can improve the valve body actual internal area, reduces circulating resistance and saves the energy.
The end face 11,12 at described valve body two ends welds with single channel valve seat and Twin channel valve seat respectively, can reduce argon arc welding welding difficulty greatly.
