Thereby, the utility model meets the needs of large flow rate of the refrigeration circuits.
Description
Technical field
Model utility is about the improvement to refrigeration loop such as refrigerator, idle call stop valve, relates in particular to a kind of bistable electromagnetic stop valve.
Background technique
Stop valve is because of the use occasion difference, and the requirement of valve is also had nothing in common with each other, and therefore is all the identical stop valve of function, and its structure difference does not have versatility between industry.As stop valve as described in Chinese patent CN2618003, CN2492709, the CN2476681, all because of complex structure, volume is bigger, and driving spring easily produces fatigue, reasons such as performance shakiness all are not suitable for refrigeration loop systems such as refrigerator, air-conditioning and use, and these valves mostly are the monostable driving mode, the energy consumption height does not more meet the energy-conservation requirement of modular refrigerating appliance.
Refrigeration loop such as refrigerator, air-conditioning stop valve not only requires to have smaller volume, low noise, and require as far as possible little power consumption, and good, the little leakage rate of cutoff performance.Existing refrigeration loop stop valve for reaching smaller volume and power consumption, reaches good cutoff performance, adopts the two-position three way bistable electromagnetic valve with dumbbell structure valve sleeve usually, and one of them outlet end sealing is converted (as Fig. 1,2).This kind stop valve, because of bistable dumbbell shape valve sleeve 9 cavity volume are placed restrictions on, its valve flow is generally less relatively, and (pressure reduction is when 0.4Mpa, the outer pipe flow is about 1000---1500l/h), for the refrigerator of the big flow of some specific (special) requirements (when the 0.02Mpa as pressure reduction, require the outer pipe flow greater than 1500l/h), this structure then is difficult to accomplish.If simply overstriking is managed in the volume and the import and export of valve, though can produce the bistable state stop valve of big flow, but can cause the long-pending significantly increase of valve body again because of importing and exporting the pipe overstriking, therefore the cost of valve is improved, and bring difficulty is installed, but also need to improve electromagnetic actuation force because of volume strengthens, make the energy consumption of valve increase, it is energy-conservation and reduce cost and also disagreing that refrigeration such as this and refrigerator machinery increasingly stringent requires, therefore is difficult to obtain the approval of refrigerator factory etc.
Summary of the invention
The purpose of model utility is to overcome the deficiency of above-mentioned prior art, provides a kind of volume little, does not increase power consumption and too many cost, but can realize the refrigeration loop bistable electromagnetic stop valve of big flow.
The model utility purpose realizes, basic design is to adopt valve liquid in-out (gas) pipe is shifted out the less bistable state driving body of original volume, thereby the spool that makes stop valve drives and liquid in-out pipe and shutoff separate, reach the driving mechanism that has both utilized former small volume, dumbbell structure bistable state valve body that power consumption is little to make valve, do not increasing under the power consumption prerequisite again, improve the through-current capacity of valve, satisfied the need of the big flow of some modular refrigerating appliance.Specifically, model utility refrigeration loop bistable electromagnetic stop valve, comprise dumbbell shape non-magnetizer sleeve pipe, the sleeve pipe two ends enlarge the magnet case valve seat in the endoporus, the magnet case spool that two valve base chambers can move back and forth, the thin shank of dumbbell shape non-magnetizer sleeve pipe has a pair of homopolarity permanent magnet opposed, sleeve pipe is arranged with the ring-type field coil outward, it is characterized in that a said end magnet case valve seat axially extends, have the through hole of being used to lead on it, lengthening part is the hollow tubular that hollows out, and hollow tube radially is provided with a valve passage, the hollow tube opening end has the sealing of another valve passage, and magnet case spool lengthening valve seat end is connected with a valve rod that passes valve seat through-hole shutoff opening end valve passage.
The said thin valve rod shutoff end of model utility, can be processed into various and the valve passage valve nozzle shape that matches, open and close noise and leakage rate for reducing valve, a kind of better is not hold at valve rod to be provided with as flexible plugging block such as rubber materials, is flexible sealing thereby make shutoff and valve chew both.
Model utility is owing to adopt the bistable state spool driving body with low power consumption, small volume, and end valve seat lengthening is provided with valve passage, and the bistable state stop valve of making, existing refrigeration is with loop bistable state stop valve, significantly strengthen valve and imported and exported the passage caliber, can realize big flow.It is little not only to have power consumption, and volume does not increase much yet, and the valve flow is increased greatly (by former pressure reduction 0.4Mpa, rate of discharge 1000---1500l/h, be increased to pressure reduction 0.02Mpa, rate of discharge is greater than 1500l/h), required to satisfy the big flow of some refrigeration loop.Be the import and export of approximate vertical, improved the sealing characteristics of valve especially.Especially adopt the flexible block shutoff, during as the shutoff liquid outlet, it also can be along with inlet pressure increases, the sealability increase that is directly proportional.
In conjunction with an embodiment, further specify the model utility structure down.
