The utility model discloses a soft-sealed flange butterfly valve, which comprises a valve body, an upper rotating shaft and a lower rotating shaft installed inside the valve body; the lower end of the upper rotating shaft is connected with a valve plate, and the upper end of the upper rotating shaft is connected with a transmission device; the outer ring of the upper rotating shaft is provided with a filler, and the connecting part of the support and the valve body is provided with a filling pressure plate; The lower end of the lower shaft is loaded into the valve body, and the upper end of the lower shaft is connected with the valve plate; the lower end of the valve body is provided with a sealing bottom cover assembly, the valve body is provided with a left chamber and a right chamber, and the first and second pressure caps are successively installed on one side of the right chamber. The butterfly valve with soft sealing flange, the isolation of filler and packing pressure plate and the function of preventing medium leakage from filler, according to the actual situation, the pipeline is selected to be connected to No. 1 or No. 2 pressure cap. When the fluid temperature is too high, the pipeline is selected to be connected to No. 2 pressure cap. Because of the increase of distance, the temperature decreases and the compensating pipe is formed. The function of the temperature difference of the road extends the service life of the valve.

一种软密封法兰蝶阀
本技术涉及蝶阀
,具体为一种软密封法兰蝶阀。
技术介绍
传统软密封蝶阀的蝶板安装于管道的直径方向,在蝶阀阀体圆柱形通道内,圆盘形蝶板绕着轴线旋转,旋转角度为0~90度之间,旋转到90度时,阀门则为全开状态,现有的软密封蝶阀功能单一,不具备补偿管道温差的功能,使用寿命短。
