Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of antiskid valve seat globe valve.
Background technique
Valve be a kind of by rotary component as flap shutter 90-degree rotation makes valve from the modulating valve opening position and be changed to off-position.In valve, the valve of ball valve to be a kind of open-shut device be spheroid, spheroid is driven by valve rod, and around the valve that the axis of valve rod rotates.
Traditional ball valve due to spheroid larger with the decrement of valve seat, cause the frictional force of spheroid and valve seat also large, driver relative resistance when closing also increases, simultaneously often also can because of the consideration of valve body compact type, valve rod packing ring is exerted pressure, increase spheroid further and rotate the friction brought, user needs larger dynamics ability switching ball.
In existing ball valve, when valve seat is ball groove structure overall parcel spheroid, after rubbing for a long time, spheroid easily drives valve seat to rotate together when axle rotates, valve seat displacement is caused easily to leak, and decrease liquid communication area, working life reduces, and so just brings certain fund and energy waste to user.
