Abstract
The utility model discloses a valve seat fixing device of a hard seal butterfly valve. The valve seat fixing device comprises a valve body and is characterized in that a valve plate is arranged in the valve body; a valve seat groove is formed in the inner wall of a valve cavity in one side of the valve plate; a valve seat is arranged in the valve seat groove and is made of hard alloy; a rubber washer is arranged on one side of the valve seat; a pressure sleeve is arranged on one side of the rubber washer and fixedly mounted on the end surface of the valve body through a bolt. The valve seat fixing device is simple in structure; a buffer cushion is added, so that the failure of the valve plate resulting from over-high-intensity collision between the valve seat and the valve plate is prevented.
Description
Technical field
The utility model relates to a kind of hard seal butterfly valve valve seat fixing device.
Background technique
In prior art, in the butterfly valve structure of hard sealing, due to valve seat and all hard metals of valve plate, very stiff and demandingly like this will cause valve seat to be easily worn and be extruded looseningly, causing the poor phenomenon of sealing.
Model utility content
The utility model object is to provide a kind of simple in structure, and the structure of adding cushion pad prevents the seal butterfly valve valve seat fixing device that between valve seat and valve plate, high-intensity collision causes valve plate to lose efficacy hard excessively.
The utility model technical solution problem provides following scheme:
A kind of hard seal butterfly valve valve seat fixing device, comprise valve body, it is characterized in that: in described valve body, be provided with valve plate, the valve pocket inwall of described valve plate one side is provided with valve seat groove, in described valve seat groove, be provided with valve seat, described valve seat adopts cemented carbide to make, and a side of described valve seat is provided with rubber washer, one side of described rubber washer is provided with gland, and described gland is mounted by means of bolts on the end face of valve body.
The cross section of described valve plate is curved.
The utility model is provided with valve seat groove on the sidewall of valve body, and in valve seat groove, valve seat is installed, and the side at valve seat is provided with rubber washer, by rubber washer, play the effect of buffering, prevent from directly contacting and causing squeeze pressure excessive between gland and valve seat, valve seat and valve plate, the prooving of valve seat is accelerated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
