多层

However, this butterfly valve in the course of the following questions remain: First, as a result of hard and soft multi-layer stacked ring fixed in the valve plate, when the valve plate when the media always state of the formation of its positive sealing surface erosion, sheet metal dissection of the soft-sealed after flushing with by a direct impact on seal performance.

但是，这种蝶阀在使用过程中仍然存在以下问题：一、由于多层软硬叠式密封圈固定在阀板上，当阀板常开状态时介质对其密封面形成正面冲刷，金属片夹层中的软密封带受冲刷后，直接影响密封性能。

First, because of soft and hard multi-layer stacked ring fixed in the valve plate, when the valve normally open status when the medium of its sealing surface to form a positive erosion, sheet metal in the interlayer by scouring with soft seal, the sealing performance of a direct impact.
