Abstract
The utility model relates to a multiple-way valve. After one coil curl of two coil curls which are arranged on the periphery of a valve core body is energized, the coil curl generates acting force to make a sliding body arranged in the valve core body move towards one direction to seal one of outlets arranged on fixing bodies which are arranged on both ends of the sliding body and switch on the other outlet. The other coil is energized, and then the sliding body moves towards a reverse direction to change the original conducting and breaking channels so as to realize the function of a two-position three-way valve. The utility model has the advantages of simple structure and high reliability. The multiple-way valve is applicable to the double-door refrigerator of a large volume freezing chamber of a direct cooling type refrigeration system, or a three-door refrigerator with a chill chamber.
Description
The utility model relates to and only comprises the movably multiple-way valve of sealing surface of a guiding valve conduct.
In recent years, China's refrigerator production develops rapidly, develops the two-door or multi-door double temperature double control refrigerator of big capacity and be the inexorable trend of several years from now on.It is one of optimum scheme of making by big capacity refrigerator that the direct cooling type that adopts the two-bit triplet solenoid valve to join the double capillary design is independently controlled refrigeration system, it is single compressor system with double compressor system that this solenoid valve changes former, have and reduce cost, energy efficient, improve refrigerating efficiency, advantages such as simplified design and manufacturing.But the two-position three-way valve of joining at present is General Construction, and accuracy of manufacturing requires high, and components and parts are many, and the reject rate height easily breaks down in the use, poor reliability.
The purpose of this utility model provides a kind of matching used two-bit triplet solenoid valve of big capacity double temperature double control refrigerator that is, it has simple in structure, the service-strong characteristics.
The purpose of this utility model is by after being arranged on two coils on the valve core periphery and making an one energising, the active force that is produced, slide mass in the valve core is moved to the left or to the right, seal an outlet on the fixed body of being located at the slide mass two ends, connect that outlet on another fixed body realizes.The valve core that is solenoid valve is made up of two fixed bodies and slide mass and shell, two fixed bodies are arranged at the interior two ends of shell of valve core respectively, be provided with an inlet passage and an outlet passage in one of them fixed body, be provided with an outlet passage in another fixed body; Slide mass floats and places in the shell, between two fixed bodies, has an axial passage, communicates with the inlet passage of fixed body; Establish two coils respectively in the periphery both sides of valve core, make a coil electricity, then slide mass is moved to a direction, disconnect and connect a passage; Another coil electricity then moves round about, changes original switching passage.
Accompanying drawing 1 is a structural drawing of the present utility model.1 is the outlet I among the figure, and 2 is the fixed body I, and 3 is slide mass, and 4 is shell, and 5 is the fixed body II, and 6 are import, and 7 are the outlet II, and 8 is coil rack, and 9 is the coil I, and 10 is the coil II, and 11 is sealing gasket.
Provide embodiment of the present utility model in conjunction with the accompanying drawings.
The present embodiment three-way magnetic valve constitutes a valve core by outlet I, fixed body I, fixed body II, slide mass 3, shell 4, import 6 and outlet II, fixed body I and fixed body II are loaded on respectively in the shell 4 of stainless steel control, place two ends, and be fixed, one passage is arranged in the fixed body I, the outside of passage connects outlet 1, and the inboard is provided with a convex shoulder, is processed into a sealing plane.Two passages are arranged in the fixed body II, and the outside connects import 6 and outlet 7 respectively, and the inboard of outlet II is provided with a convex shoulder equally, is processed into a sealing plane.Slide mass 3 floats and is installed in the shell 4, and between two fixed bodies, there is certain interval the centre, is provided with an axial passage in the slide mass, and the inlet passage position of corresponding and fixed body 5 has a circular groove, to link up inlet passage and axial passage.With respectively be provided with a sealing gasket 11 on the corresponding position of fixed body outlet passage, excellent sealing performance is arranged when guaranteeing pathway closure.Slide mass and fixed body are made by the strong industrial soft iron of magnetic conductivity, are enclosed in the shell 4 that Stainless Steel Tube makes.The periphery of shell 4 is equipped with coil rack 8, inserts coil I 9 and coil II 10 in its coil mounting point respectively.
Promptly connect with compressor when inserting the alternating current 220V power supply when coil 1 energising, slide mass is moved to the left by the electromagnetic force effect, and export 1 and close this moment, and the working medium flow direction is 3 to advance, 2 go out.
When coil 2 energising, slide mass is moved right by the electromagnetic force effect, and export 2 and close this moment, and it is 3 to advance, 1 go out that working medium flows to.
The utility model electromagnetic valve structure is simple, novel, uses reliably, is applicable to the double-door refrigerator of the big volume refrigerating chamber of direct cooling type refrigeration system or the three-door refrigerator of icing the greenhouse is arranged, and also can be used in the occasion that the need that power supply is similarly arranged are used two-position three-way valve.
