More Information
Summary:The utility model discloses a device for locking a valve seat on a valve body. The device comprises the valve body with a slot and the valve seat with a salient, wherein a movable pin is arranged in the slot, and the salient is jointed to the slot, so that the pin can move when the valve seat rotates from an unlocking position to a locking position, relative to the valve body. The utility model provides a self-locking valve seat which is in matching with a process fluid with a wider temperature variation range (for example from 100 below zero DEG F to 1100 DEG F) for use, and the valve seat is conveniently maintained and changed. With the adoption of the self-locking valve seat, the needs of fixing the valve seat to the valve body by virtue of an expensive bolt or welding are eliminated, and due to the self-locking function, the valve seat does not need to be additionally arranged on a valve box and/or a whole component does not need to be clamped on the valve body.
