Abstract
The utility model relates to a mold pressing semi-coated rubber stopcock spool, specifically to moving parts for controlling the on and off of the plug valves or regulating the flow of the plug valves to ensure the plug valve has reliable function of on and off or flow regulating and belongs to the technical field of mechanical structure. The mold pressing semi-coated rubber stopcock spool comprises a metal core and a rubber. The mold pressing semi-coated rubber stopcock spool is characterized in that the working surface of the metal core is coated with rubber. The mold pressing semi-coated rubber stopcock spool is simple, compact, and reasonable in structure. The working surface of the metal core of the mold pressing semi-coated rubber stopcock spool being coated with rubber doesn't affect the working performance of the plug valve, thereby stable quality and long service life are obtained, and moreover, the rubber coverage area is reduced to take up only 40% of the overall coverage area, so that the material cost of the rubber is saved and the market competitiveness of the product is improved.
Description
Technical field
The utility model relates to a kind of mold pressing half rubber-coated plug valve spool, 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
,Valve in outlet developed country for tap water and water treatment pipeline adopts the eccentricity rubber seal stopcock mostly, and valve body sealing surface is formed by the nickel alloy built-up welding, and spool (stopper) then is rubber-coated forming on metal core.In the rubber-coated technology of existing spool, it is to adopt integral die to coat that a kind of method is arranged, and it has steady quality, the characteristics of long service life.On the other hand, owing to adopt integral coating, also cause the rubber area coverage large, the shortcoming that cost of material is high.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of mold pressing half rubber-coated plug valve spool is provided, and its rubber coated area is little, and the cost of material is low, steady quality, long service life.
According to the technological scheme that the utility model provides, mold pressing half rubber-coated plug valve spool comprises metal core and rubber, and feature is: the working surface of described metal core is rubber-coated.
The area of described rubber coated metal core reaches 40%.Described rubber thickness is 5～15 millimeters.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Its working surface at metal core is rubber-coated, does not affect the service behaviour of stopcock, steady quality, long service life.Reduce simultaneously the area coverage of rubber, only needed 40% of integral coating area, greatly reduced the cost of material of rubber, improved the competitiveness of product in market.
Description of drawings
Fig. 1 is that the utility model structural principle uses phase diagram.
Fig. 2 is the structural drawing of stopcock spool.
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: comprise valve body 1(valve body sealing surface 1-1), the rubber-coated 2-1 of spool 2(, metal core 2-2), medium inlet passage 3 and media outlet passage 4.Described spool 2 is comprised of the rubber 2-1 of metal core 2-2 and first coating of metal core 2-2.The material of described metal core 2-2 is spheroidal graphite cast iron, and only at the rubber-coated 2-1 of its working surface, thickness is generally 5～15 millimeters.Described rubber 2-1 generally adopts synthetic rubber, and the area of clad metal fuse 2-2 reaches 40%.
Position shown in Figure 1 is to be in closed condition, and medium inlet passage 3 and media outlet passage 4 are cut off.When spool 2 rotates along the direction of arrow, rubber 2-1 on the spool breaks away from valve body sealing surface 1-1 gradually, medium inlet passage 3 and media outlet passage 4 are connected, medium flows into media outlet passage 4 from medium inlet passage 3, the Spool rotating angle can be regulated in 0 ~ 90 °, thereby the adjusting rate-of flow, when Spool rotating to 90 °, rate-of flow maximum (full open position).When the diagram closed condition, rate-of flow is zero (not allowing to leak), and it mainly is that the sealing pair that leans on rubber 2-1 and valve body sealing surface 1-1 to form guarantees.In prior art, rubber generally passes through hot-die mold pressing integral coating on metal core.Rubber 2-1 in the utility model has only coated the working surface of metal core 2-2.When guaranteeing the spool service behaviour, greatly having reduced the coating area of rubber thus, only is 40% of integral coating area.
Facts have proved that the utility model steady quality is reliable, the life-span is long, and cost is low, and the market competitiveness is high.
