As a kind of improvement of the present utility model, in described tie layer, be provided with four couples of attaching nuts and be movably connected on valve body; By four couples of attaching nuts in tie layer, conveniently valve body is stablized and is connected with the formation between connecting pipeline, improve the connective stability of whole pipeline, dismounting simultaneously and replacing are conveniently.
As a kind of improvement of the present utility model, in described sealing layer, be filled with elastic packing rubber, the overall structure that described elastic packing rubber is ring, the thickness of described elastic packing rubber is 1.0～1.2cm; The integrated cast molding of described fixed bed and valve body, described tie layer is dead slot structure; By sealing layer, form stable connection with the elastic seal ring on dish plate, prevent the wearing and tearing between dish plate and valve body, coordinate integrated fixed bed and valve body structure simultaneously, improved the sealability of single unit system, by forming stable connection between valve body and pipeline, simple to operation by tie layer.
As a kind of improvement of the present utility model, described fixed bed is provided with through hole, and described stop nut is connected on the elastic packing rubber in sealing layer through through hole; By the through hole on fixed bed, coordinate stop nut structure, guaranteed that elastic packing rubber forms stable connection with the seal ring on butterfly plate, greatly improved the sealability of valve body, improved the compressive region of device.
As a kind of improvement of the present utility model, the diameter of described sealing layer is greater than the internal diameter 1.6～2.0cm of valve body; Because the diameter of the elastic seal ring of dish plate surrounding own is greater than the internal diameter 1.6～2.0cm of valve body, facilitate valve body stable being embedded in sealing layer of elastic seal ring energy when closing, simultaneously elastic seal ring with by forming to stablize with elastic packing rubber, be connected, the stable sealing effect of assurance device.
The utility model has the advantage of: the utility model by adding sealing layer on the valve body of butterfly valve, surrounding at dish plate is added elastic seal ring, elastic seal ring with by forming stable connection with elastic packing rubber, coordinate integrated fixed bed and valve body structure, the stable sealing effect of assurance device; Improved sealability and the compressive region of valve body, by tie layer, will between valve body and pipeline, form stable connection simultaneously, dismounting and change conveniently good practical effect.
