Abstract
The utility model relates to a spool structure of a plug valve, particularly to a moving part for controlling the opening and closing of the plug valve or regulating the flow, and belongs to the technical field of mechanical structures. The spool structure comprises a metal core, a rubber layer, a plug and a web, wherein the rubber layer is coated outside the metal core, the plug is fixed in a through hole of the metal core through welding, a cavity is reserved in the metal core, and the web is arranged in the cavity. The spool structure is simple, compact and reasonable; the cavity is reserved in the metal core during casting and is provided with the web; the strength is guaranteed when the material volume of the product is reduced, and the material cost is reduced by about 30%; simultaneously, the moment of inertia of the spool is reduced, the flexibility of a rotor is improved when the service life is guaranteed, and the market competitiveness of the product is improved; and reliable opening, closing and regulating functions are guaranteed for the valve.
Description
Technical field
The utility model relates to a kind of stopcock valve core structure, specifically is used for the movement parts of the keying of control cock valve or adjust flux, guarantees that valve has the function that opens and closes or regulate reliably.Belong to the mechanical structure technical field.
Background technique
At present
,Be used for the valve of tap water and water treatment pipeline in outlet developed country, mostly adopt the eccentricity rubber seal stopcock, valve body sealing surface is formed by the nickel alloy built-up welding, and spool then is rubber-coated forming on metal core.In the rubber-coated technology of existing spool, metal core adopts solid construction more, like this casting and easy to process, but it is high also to exist cost of material, the shortcoming that valve core rotation inertia is large.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of stopcock valve core structure is provided, and it is simple in structure, compact, reasonable, and the cost of material is low, and rotary inertia is little, long service life.
According to the technological scheme that the utility model provides, a kind of stopcock valve core structure comprises metal core, and feature is: also comprise rubber layer, stopper, web; Described rubber layer is coated on the outside of metal core, and described stopper is fixed by welding in the through hole of metal core; Cavity is left in described metal core inside, is provided with web in cavity.
As a further improvement on the present invention, described rubber layer adopts synthetic rubber, and synthetic rubber thickness is 5～15 millimeters.
Through hole on the described metal core is made as three as a further improvement on the present invention, matches with three stoppers.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; When the casting metals fuse just within it section leave cavity, in the cavity also with web.When reducing the product material volume, guarantee the intensity of product.Cost of material can descend about 30%, has reduced simultaneously the rotary inertia of spool, and the flexibility that has improved rotor when ensureing working life has improved the competitiveness of product in market.

Fig. 2 is the A-A view of Fig. 1.
Embodiment
Following the utility model is further described in connection with the embodiment in the accompanying drawing:
As shown in Figure 1 and Figure 2: a kind of stopcock valve core structure comprises rubber layer 1, metal core 2 and stopper 3.Described rubber layer 1 is coated on the outside of metal core 2, and rubber layer 1 adopts common synthetic rubber, and thickness is 5～15 millimeters, and metal core 2 adopts ductile cast iron material to make.Described stopper 3 is fixed by welding in the through hole of metal core 2.Cavity 2-1 is also left in described metal core 2 inside, and is provided with web 2-2.
In the prior art, metal core inside mostly is solid.Leave 3 through holes on the metal core 2 of the present utility model so that when casting reserves cavity 2-1 in inside, and form web 2-2.After the casting, need to block through hole by welding with stopper 3.At last, coated rubber layer 1 in metal core 2 outsides by the hot-die mold pressing.Can guarantee manufacturing and the quality of processing of product by such technique.Reduce product weight, when reducing valve core rotation inertia, guaranteeing the intensity of spool by web 2-2.The cost that has reduced product has improved the flexibility of rotating simultaneously, has improved the competitiveness of product in market.
