Description
Technical field
The present invention relates to a kind of rotary type multi-way switching valve, it is mainly used in the high end home use in refrigerator refrigeration system, the different flow directions and the size of control refrigeration agent.
Background technique
Along with improving constantly of quality of life, the high end home refrigerator is required to realize control of multi-region section temperature and the soft Refrigeration Technique that food is insured more, existing two-bit triplet refrigerator solenoid valve can't satisfy above-mentioned requirements, existing two-bit triplet refrigerator solenoid valve is driven by electromagnetic coil, the spool straight line motion has only two working positions can't realize the multichannel multiposition control, the valve port hole of the rotating solenoid valve of other structure likeness in form is distributed on the circumference of same diameter, a valve port state so just can only be set on identical angle of swing, therefore restricted the setting of valve port quantity, control way and state of a control are reduced, can't realize combination refrigerator refrigerant various control state.
Summary of the invention
The objective of the invention is to propose a kind ofly can realize the more rotary type multi-way switching valve of the conversion of multichannel number in identical angle of swing, it can solve problems of the prior art.
The present invention can be solved by the following technical solutions:
A kind of rotary type multi-way switching valve, it is by step motor drive, comprise outer cover, axle, rotor, and the valve seat of rotor bottom, described rotor is nested with on axle and in this rotor lower end surface and is provided with slide block, this slide block rotates with rotor under described step motor drive, a plurality of concentric circumferences of described valve seat upper-end surface are provided with and pass in and out the valve port that connecting tube communicates, and at least 2 valve ports in same footpath upwards, and one or more valve ports are set on each circumference, the axial bottom end of described slide block be provided with at least 2 different radiis and with the boss plane of wherein corresponding described valve port coupling sealing, and the upper-end surface of described slide block is provided with a stage clip, and be inserted in the described rotor lower end this stage clip upper end.
Slide block of the present invention center is the equilateral hexagon hole, the axle coupling assembling one of itself and hexgonal structure.
It around the equilateral hexagon hole of upper end of slide block face of the present invention the pit of fixing described stage clip.
Circular arc type is adopted on boss of the present invention plane, and its arc length is corresponding with the position of described valve port.
Owing to adopt above technological scheme, rotary type multi-way switching valve of the present invention adopts step motor drive, the motion mode of rotation, can be in arbitrarily angled stop, because at least 2 valve ports make progress (radius does not wait, and angle is identical) in the same footpath that is arranged on concentric in the control valve port of this new structure, therefore when spool rests on a certain position, can carry out switch control simultaneously to a plurality of valve ports, realize the combination of refrigeration agent various states.
