Abstract
The utility model provides a kind of limiting valve of pressure cooker, comprises inner valve body and outer valve; Inner valve body injection mo(u)lding, in outer valve, is provided with spool in inner valve body, and outer valve outer surface is provided with antirust coat, and outer valve is provided with bonnet.Application the technical solution of the utility model, the inner hole wall part of pressure limiting valve is wrapped up by working of plastics single injection-molded, outer surface metal plating, inside and outsidely all reaches antirust function, and outer surface is still metal, sturdy and durable.
Description
Technical field
The utility model relates to cooking equipment, in particular to a kind of limiting valve of pressure cooker.
Background technology
The valve body of limiting valve of pressure cooker of the prior art is metalwork, usually adopts the surface treatment mode of ironware plating to carry out antirust.But because of the limitation of electroplating technology, the plating of valve body inner bore wall portion is insufficient, causes the bore section of pressure limiting valve body easily to get rusty.
Have a kind of scheme to be that valve body channel floor uses stainless steel material to make, although this scheme can reach antirust object, stainless material expensive, causes high cost.
Also have a kind of scheme to be meet the antirust function of pressure limiting valve, pressure limiting valve body metallic member and metal spool part are wrapped in inside plastics by twice injection mo(u)lding entirety.This scheme requirement on machining accuracy is high, and cost is also high, and non-dismountable, causes cleaning difficulty.In addition, pressure limiting valve outer surface is that working of plastics is also easily damaged.
Utility model content
The utility model aims to provide a kind of limiting valve of pressure cooker, to solve the problem that limiting valve of pressure cooker bore section of the prior art easily gets rusty.
To achieve these goals, the utility model provides a kind of limiting valve of pressure cooker, comprises, inner valve body and outer valve, and inner valve body injection mo(u)lding, in outer valve, is provided with spool in inner valve body, and outer valve outer surface is provided with antirust coat, and outer valve is provided with bonnet.
Further, the outer surface of outer valve forms antirust electrodeposited coating through antirust treatment.
Further, outer valve outer surface forms oxide-film or overlay film through antirust treatment.
Further, spool is arranged in bonnet, and removably connects with inner valve body.
Further, spool is threaded with inner valve body.
Further, outer valve is made up of cast iron or mild steel or ferrite.
Further, antirust electrodeposited coating is zinc coat, galvanized alloy layer, silver coating or silver-plated alloy-layer.
Further, outer valve is provided with the endoporus that cross section is " work " font, and inner valve body is molded in endoporus.
Further, bonnet is threaded connection with outer valve or buckle is connected.
Application the technical solution of the utility model, the inner hole wall part of pressure limiting valve is wrapped up by working of plastics single injection-molded, outer surface metal plating, inside and outsidely all reaches antirust function, and outer surface is still metal, sturdy and durable.
Accompanying drawing explanation
The Figure of description forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 shows the sectional view of the embodiment of limiting valve of pressure cooker of the present utility model.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
After pressure limiting valve body metal surface is electroplated by the utility model, adopt half packet mode, by inner hole wall part and working of plastics one-body molded (single injection-molded), inner hole wall plating thin weak part is all wrapped up by working of plastics, outer surface metal plating part is constant, thus reach antirust function, and outer surface is still metal, sturdy and durable.Spool is connected with valve body screw thread, can arbitrarily dismantle, thus arrives the object of easy cleaning.Preferably, if do not take plating, outer valve outer surface also can form oxide-film through antirust treatment or overlay film plays antirust object.Preferably, valve body is made up of cast iron or mild steel or ferrite, is convenient to plating.Preferably, electrodeposited coating can be any one in zinc coat, galvanized alloy layer, silver coating or silver-plated alloy-layer.
Pressure cooker pressure-limiting valve body 11 of the present utility model is linked together by injection moulding integrated molding by inner valve body 22 and outer valve 21, inner valve body 22 is working of plastics, outer valve 21 is metalwork (such as ironcasting), and the outer surface 24 of outer valve 21 carries out surperficial antirust treatment, such as, electroplate.The inner surface 23 of outer valve 21 is closely wrapped up by inner valve body 22, cannot with extraneous contact.Spool 13 is embedded in bonnet 12, and is together by a threaded connection with inner valve body 22.Outer valve is provided with the endoporus that cross section is " work " font, and described inner valve body is molded in described endoporus.Bonnet is threaded connection with outer valve or buckle is connected.
The outer surface 24 of outer valve 21 is by after other antirust treatment such as plating, reach the object effectively preventing from getting rusty, inner surface 23 is because closely being wrapped up by inner valve body 22, the material of metal rusting easily cannot be caused to contact with water etc. with the air in the external world, also antirust object can be reached, inner valve body 22 is working of plastics, and material itself cannot oxidized rust corrosion, thus makes the object that whole pressure limiting valve can reach antirust.
As can be seen from the above description, the utility model the above embodiments achieve following technique effect:
Inner hole wall part is wrapped up by working of plastics, and outer surface metal plating, reaches antirust function, and outer surface is still metal, sturdy and durable.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
