Description
Technical field
The present invention relates to a kind of diaphragm type pilot control electromagnetic valve, belong to Solenoid Valve Technology field.
Background technology
Control valve field frequently refers to electromagnetic valve, break-make with control system medium, according to difference in functionality demand in system, open in usual, normally closed type can be divided into again, Direct Action Type and pilot-operated type can be divided into again according to electromagnetic valve internal structure, guide electromagnetic valve generally requires by the internal less aperture (pilot valve) of solenoid band moving electromagnetic valve, after pilot valve is opened, the seal-moving part being sealed on large hole mouth can be made to open bigger valve port (main valve) under the effect of pressure reduction, thus realize the effect of control system medium break-make.
In recent years, aggravation along with global warming situation, whole world environmental consciousness gradually strengthens, the R12 commonly used in refrigeration system, the cold-producing mediums such as R22 have the biggest destructiveness to air, the most gradually substituted by the environmental protection refrigerant without freon, such as R410A etc., but the evaporating pressure of R410A coolant compares R12, R22 is big, during refrigerant circulation work, the pressure differential importing and exporting formation at electromagnetic valve is bigger, cause the electromagnetic valve supporting more powerful coil of palpus, electromagnetic valve otherwise will be caused to open difficulty or action will be unreliable, the import and export maximum operating pressure differential the most how increase electromagnetic valve can reach on the premise of supporting smaller power coil is the problem that we need to solve.
Simultaneously incrementally increasing along with individual's living space in recent years, and the increasing of the building such as megastore, jumbo air conditioning unit demand the most gradually increases, in such large capacity conditioner unit, the capacity bore of electromagnetic valve is also required that bigger, however as society's economy consciousness and aesthetic raising, require that refrigeration system and part need further miniaturization on the premise of meeting function, the most to sum up, design that a structure is the smallest and the most exquisite but also to be suitable for the electromagnetic valve of bigger evaporating pressure cold-producing medium be the problem that we need solution badly.
In prior art, patent CN200620100262 discloses a kind of sealing member A formula electromagnetic valve for controlling rate-of flow applied for refrigeration and industrial circle, this electromagnetic valve structure pilot valve mouth and the sealing member A sealing primary valve link together, the most just the movement travel making pilot valve core iron can become much larger along with the increase in primary valve aperture, the most just bigger to the power requirement of supporting coil, cost is higher, and product also can not be accomplished small and exquisite.
In another one prior art, patent CN200420110999 discloses a kind of heavy caliber guide electromagnetic valve, typical guide electromagnetic valve main valve as said above is relevant to pilot valve stroke, along with main valve valve port bore increases, coil power is also with increase, and this patent valve body structure have employed the structure that main valve separates with pilot valve, on the premise of not increasing coil power, effectively increasing valve port bore, but described electromagnetic valve body structure is complicated, difficulty of processing is bigger.
Summary of the invention
It is an object of the invention to provide a kind of diaphragm type pilot control electromagnetic valve, this electromagnetic valve body structure can be accomplished simple, small and exquisite, make valve body import and export two ends maximum operating pressure differential allowable bigger, to be suitable for the environmental protection refrigerant without freon of high evaporating pressure difference simultaneously.
