Description
Technical field
The utility model relates to a kind of magnetic valve, particularly a kind of magnetic valve of refrigerator control refrigerant flow direction.
Background technology
At present, the refrigeration system of refrigerator can be divided into direct cooling system and indirect cooling system.Though direct cooling system has its intrinsic advantage on energy savings and applicability, but a shortcoming is arranged in the requirement of satisfying capacity, when net capacity surpasses 230 liters, the humidity control method that it is traditional, for the good cold balancing that Keep cool between chamber and the refrigerating chamber become powerless.Though the indirect-cooling domestic refrigerator can overcome above-mentioned shortcoming, but because it has increased the fan electromotor and the high-power heater of a cold air circulation, increased the cold air air channel loss of forced convertion with fashion, therefore its energy consumption is than direct-cooling type system height, for satisfying the volume that should increase refrigerator, requirements of saving energy again, developed at present a kind of novel direct-cooling type domestic refrigerator system: the direct-cooling type autonomous control system, thus in system, adopted a two-position three way magnetic valve to distribute with the balance that the flow direction of control cold-producing medium in the circulatory system reaches cold in the refrigerator.The composition of this two-position three way magnetic valve comprises the valve body of a tubulose, but be mounted with the spool of move left and right in the valve body, one end single hole of valve body is mounted with on extremely and often drives outlet, the diplopore of the other end is mounted with feed tube and normally closed outlet on extremely, the valve body of tubulose is equipped with the move left and right of solenoid with the application valve body inner spool outward, thereby reaches the purpose that switch single hole utmost point valve port and switch diplopore utmost point valve port change flow direction.But the magnetic valve of this structure is but found in actual use, because of spool externally move left and right and close port under the control of solenoid, its action is very fast, thereby the bigger impulsive force of generation knocks, this not only has influence on the product quality of domestic refrigerator, and influences the service life of product.A kind of domestic refrigerator magnetic valve that has on the present market, mainly be on corresponding valve port limit, the spool two ends of two-position three way, respectively to be provided with buffering spacer, this buffering spacer is made by elastomeric material, also be glued with a metal washer on it, can reduce and use noise, but because the cost of rubber washer and metal washer is higher, and need to run into be just to play cushioning effect, and ordinary circumstance does not need two ends that buffering spacer all is set.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to propose a kind of flow direction that can effectively control refrigerating fluid that can address the above problem, the product quality that can improve domestic refrigerator again makes it to use reliable, is swift in motion and the minimum use in refrigerator magnetic valve of action noise.
The purpose of this utility model is achieved in that and is provided with bolster at the spool of use in refrigerator magnetic valve corresponding to diplopore utmost point valve port place.
In other embodiment of the present utility model: bolster can be arranged on spool corresponding to diplopore utmost point valve port place; Also can diplopore utmost point valve port place and single hole utmost point valve port place all be provided with.
Further: bolster can be buffer spring or spring shim.
Further: can buffer spring be set a place, another place is provided with elastomeric pad.
The utility model is owing to settled elastomeric pad or buffer spring in valve body, the strike note of core iron and valve body reduces noise greatly when having reduced use widely, has improved product quality simultaneously, having improved the quality of domestic refrigerator, is the effective improvement to existing domestic refrigerator magnetic valve.Advantage such as have unique, simple in structure, easy to use and reliable, reduction noise novel in design, improve the quality of products.
