Abstract
The utility model relates to an all-packaging anti-rust pressure limiting valve which comprises an iron body (1) and a valve core (3), wherein a plastic body (2) is arranged between the iron body (1) and the valve core (3); the inner side surface and the bottom of the iron valve body (1) are tightly packaged by the plastic valve body (2); and the valve core (3) is arranged on the plastic body (2). The whole iron valve body is packaged by the plastic valve body and a plastic valve stem, so the utility model has the advantages of low cost and no rust, and solves the problem of the prior electric pressure cooker that the iron valve body rusts and the copper valve body has high cost. In addition, the utility model has the advantages of simple structure, convenient use and mass production, and is favorable for promoting.
Description
Technical field
The utility model belongs to household electrical appliance technical field, relates in particular to a kind of pressure limiting valve that is used for electric pressure cooking saucepan.
Background technology
The pressure limiting valve that electric pressure cooking saucepan uses on the existing market generally is that material surface chromium plating process of surface treatment such as (or) nickel plating of iron or copper is handled, compress into the plastic shell the inside of forming then by the smelting tool, because the hole of pressure limiting valve is deep, material is that the valve body of iron is difficult to plate in doing surface-treated such as plating process, and the product valve body that causes easily that pressure limiting valve is long-term and acid, alkali, salt directly contact in actual use gets rusty, and has influenced the food hygiene of cooking food.
Material is that the valve body of copper can play antirust purpose to a certain extent after electroplating, but because the price of copper is higher, has increased manufacturing cost.
Summary of the invention
In order to solve the existing problem that electric pressure cooking saucepan iron valve body gets rusty and copper valve body cost is high, the utility model provides a kind of and wrapped the antirust pressure limiting valve of full-enclosed of one deck plastic cement structure at iron valve body periphery, and it is simple in structure, low-cost, non-corrosive, the easy to use batch process in batches.
The utility model solves the technical scheme that its technical problem adopts:
The antirust pressure limiting valve of this full-enclosed comprises iron valve body, spool, is provided with the plastic cement valve body between iron valve body and the spool, and this plastic cement valve body packs tightly inner surface and the bottom at the iron valve body; Spool is located on the plastic cement valve body.Like this, the inboard of iron valve body and bottom are protected by the plastic cement valve body, can not get rusty, and result of use is good.
The utility model can be further perfect by following manner:
The iron valve body outside is provided with the plastic cement valve handle, and this plastic cement valve handle packs tightly the outer surface at the iron valve body.The iron valve body outside is just protected by the plastic cement valve handle like this, can not get rusty, and result of use is good.
The beneficial effects of the utility model: the utility model encases iron valve body integral body with plastic cement valve body and plastic cement valve handle, and its cost is low, can not get rusty again, has solved the problem that existing electric pressure cooking saucepan iron valve body gets rusty and copper valve body cost is high.In addition the utility model simple in structure, easy to use, can produce in batches, help promoting.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Description of reference numerals: 1. iron valve body 2. plastic cement valve bodies 3. spools 4. plastic cement valve handles 5. jump rings.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing, the antirust pressure limiting valve of this full-enclosed described in the utility model comprises iron valve body 1, spool 3, is provided with plastic cement valve body 2 between iron valve body 1 and the spool 3, and this plastic cement valve body 2 packs tightly inner surface and the bottom at iron valve body 1; Iron valve body 1 outside is provided with plastic cement valve handle 4, and this plastic cement valve handle 4 packs tightly the outer surface at iron valve body 1.Spool 3 is located on the plastic cement valve body 2.The bottom of plastic cement valve body 2 is provided with jump ring 5.Like this, whole iron valve body 1 is just encased by plastic cement, and the iron valve body can not got rusty easily, can use for a long time, and its cost is also very low, and result of use is good.
Add man-hour, at first tap a blast furnace valve body 1 and stainless steel spool 3 (valve core material also can be copper) are processed in turning, then spool 3 and iron valve body 1 are placed the die cavity injection moulding that has designed respectively, and the straight body face with iron valve body 1 small end during placement is located.After first injection mo(u)lding, take out valve component, turning processes the jump ring groove of bottom, and then puts into another width of cloth mould quadric injection mould moulding, the pressure limiting valve assembly that is wrapped entirely.
