Description
Technical field
The utility model relates to the valve mechanism field, refers more particularly to a kind of novel seal butterfly valve.
Background technique
Butterfly valve is parts the most frequently used in the mechanical industry, in the giving of water supply industry, drainage pipe, small reservoir etc.; At present in the butterfly valve of piping facility used, great majority all were to adopt the interference size or the single seal ring of sealing to seal, and through interim use, because that abrasion deformation causes is poorly sealed, leakage occurred; The corrosion and the use of seal ring also can be worn; Make valve reduce the effect of sealing, and can not work normally, enterprise's ordinary production of valve is used in influence greatly on the one hand; And cause serious economy loss, bring great inconvenience also on the other hand people's life.
The model utility content
The purpose of the utility model provides a kind of novel seal butterfly valve of simple in structure, good sealing effect to above-mentioned deficiency.
The utility model is realized through following mode:
A kind of novel seal butterfly valve mainly includes valve body 1, valve seat 2, butterfly plate 3, valve rod 4, rubber gasket 5, turbine 6; Valve seat 2 is located in the valve body 1, and butterfly plate 3 is arranged on the valve rod 4, and is positioned at valve seat 2; Valve rod 4 is arranged within valve body 1, the valve seat 2; It is characterized in that: on the rubber gasket 5 sheathed valve rods 4, and be positioned at valve body 1 top; Turbine 6 is connected with valve body 1 bolt, and is positioned on the rubber gasket 5; Described valve seat 2 is a hollow circuit cylinder chamber shape; Valve seat 2 is provided with valve rod hole 21; The inwall of described valve rod hole 21 is provided with stepped tongue and groove 22.
Said tongue and groove 22 is made up of groove 221 and convex tendon 222, is provided with a groove 222 between two convex tendons 222; Be equiped with seal ring in the described groove 221.
The inwall of the valve rod hole 21 of the utility model on valve seat 2 is provided with stepped tongue and groove 22, in stepped tongue and groove 22, is equiped with seal ring, realizes multi-layer sealedly, can prevent heads.
In sum, the utility model is a kind of novel seal butterfly valve of simple in structure, easy to operate, good seal performance.
