Abstract
The utility model discloses an antirust pressure-limiting valve of an electric pressure cooker. In the traditional pressure-limiting valve structure, the whole iron valve body is coated by plastic and can prevent the rusting; and however, due to being respectively independent, the iron valve body and a valve core are connected into a whole by secondary injection through plastic cement, so the manufacturing process is troublesome. The antirust pressure-limiting valve is characterized in that an aluminum press plate is riveted at the top of the iron valve body; a stainless steel thimble is riveted on a center hole of the aluminum press plate; the iron valve body, the stainless steel thimble and the aluminum press plate are arranged in a plastic casing; the whole iron valve body is wrapped by the plastic casing; an exhaust channel formed by the plastic casing wall is arranged below the aluminum press plate; the aluminum pressure plate is provided with a plurality of vent holes communicated with the exhaust channel; and the plastic casing is provided with exhaust holes communicated with the vent holes. The utility model has favorable antirust effect; and since a valve body assembly is in an integral structure, the antirust pressure-limiting valve can be manufactured by one-step injection and is convenient to process.
Description
Technical field
The utility model relates to the electric pressure cooking saucepan accessory, specifically a kind of antirust pressure limiting valve that is used for electric pressure cooking saucepan.
Background technology
The valve body of electric pressure cooking saucepan pressure limiting valve generally adopts stainless steel body or surface through iron (copper) valve body after the antirust plating at present, is pressed into then in the good plastic casing of injection mo(u)lding, and plastic casing encases valve body top and partial sidewall.Because iron valve body inner bore and groove are difficult to carry out antirust plating, rust-proof effect is poor, and its exposed parts contacts with acid, alkali, salt etc. in that the product use is medium-term and long-term, very easily causes valve body to get rusty and influences food hygiene.Material is that the valve body of stainless steel or copper is higher owing to price, and batch process can significantly increase manufacturing cost.
China Patent No. 200820084190.X discloses a kind of pressure limiting valve structure, whole iron valve body is encased by plastic cement, though can prevent to get rusty, but because iron valve body and spool are independent separately, directly do not link into an integrated entity, need could the two be fused by plastic cement through quadric injection mould, manufacturing process is loaded down with trivial details.
The utility model content
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and a kind of favorable rust preventing effect, simple in structure, the easily manufactured antirust pressure limiting valve of electric pressure cooking saucepan are provided.
For achieving the above object, the utility model adopts following technical scheme: the antirust pressure limiting valve of a kind of electric pressure cooking saucepan, comprise iron valve body and stainless steel thimble, it is characterized in that: an aluminium pressing plate is riveted at the top of iron valve body, described stainless steel thimble is riveted on the centre bore of aluminium pressing plate, described iron valve body, stainless steel thimble and aluminium pressing plate place in the plastic casing, and described plastic casing encases whole iron valve body; The exhaust passage that the below of aluminium pressing plate has a plastic housing body wall to form has a plurality of passages that communicate with the exhaust passage on the aluminium pressing plate, have the steam vent that communicates with passage on the plastic casing.The utility model is riveted into valve body assembly by iron valve body, aluminium pressing plate and stainless steel thimble, again the whole valve body assembly is put into the mould of plastics injection moulding, and the plastic casing after the moulding all encases the iron valve body, only exposes stainless steel thimble and part aluminium pressing plate.
The antirust pressure limiting valve of above-mentioned electric pressure cooking saucepan, the plastic casing bottom that is positioned at stainless steel thimble below has a jump ring groove, the built-in jump ring of described jump ring groove, jump ring is used for the utility model and pot cover clamping.
The beneficial effects of the utility model are: plastic casing has encased whole iron valve body, favorable rust preventing effect; Because valve body assembly is structure as a whole, and adopts an injection moulding can finish manufacturing of the present utility model, and is easy to process; Simultaneously the aluminium pressing plate adopts the lower aluminium of relative mould of plastics hardness, and during the injection moulding matched moulds, mould can be in upper and lower two plane positioning of aluminium pressing plate, can not improve die life because of matched moulds collision mold damage repeatedly.
Below in conjunction with Figure of description and embodiment the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The antirust pressure limiting valve of electric pressure cooking saucepan as shown in the figure, the top riveted joint aluminium pressing plate 3 of iron valve body 2, stainless steel thimble 4 is riveted on the centre bore of aluminium pressing plate 3, and iron valve body 2, stainless steel thimble 4 and aluminium pressing plate 3 place in the plastic casing 1, and described plastic casing 1 encases whole iron valve body 2.The exhaust passage 5 that the below of aluminium pressing plate 3 has a plastic housing body wall to form has a plurality of passages that communicate with the exhaust passage 6 on the aluminium pressing plate, have the steam vent 7 that communicates with passage on the plastic casing.The plastic casing bottom has jump ring groove, the built-in jump ring 8 of described jump ring groove.
Processing method of the present utility model is as follows: tap a blast furnace valve body 2, aluminium pressing plate 3, stainless steel thimble 4 of machined at first; Then with aluminium pressing plate 3 rivetings on the iron valve body 2, with stainless steel thimble 4 rivetings on the centre bore of aluminium pressing plate 3, form valve body assembly; Again valve body assembly is placed supporting with it mould of plastics injection moulding, the plastic casing 1 that obtains the iron valve body is all encased two plane positioning of aluminium pressing plate (when valve body assembly is placed with); The bottom turning of the plastic casing 1 that comes out in injection moulding at last processes the jump ring groove, and jump ring 8 is placed in the jump ring groove, promptly obtains antirust pressure limiting valve described in the utility model.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should fall within the protection domain of the present utility model.
