新型小型波纹管阀门密封
摘要：
一种新型小型波纹管阀门密封，由波纹管阀门、阀座、阀盖和阀杆等组成。波纹管阀门以波纹管作为外密封元件,波纹管一端焊接固定在阀盖和阀座上,另一端焊接在阀杆上,阀杆上下运动带动波纹管压缩或拉伸；通过波纹管及其波纹管与阀杆可靠的焊接将阀杆与阀腔内的流体完全隔断,从而达到隔离外泄漏源的目的,保证流体绝无外泄漏的通道；通过波纹管及其波纹管与阀杆可靠的焊接将阀杆与阀腔内的流体完全隔断,从而达到隔离外泄漏源的目的,保证流体绝无外泄漏的通道；选择具有较高机械强度的波纹管材料,本阀门用波纹管的波形确定为单层U型波纹结构。
摘要（英）：

A novel small corrugated pipe valve seal is formed by a corrugated pipe valve, a valve seat, a valve cover and a valve rod. A corrugated pipe works as an external sealing member; one end of the corrugated pipe is welded on the valve cover and the valve seat and the other end is welded on the valve rod; the valve rod moves up and down to drive the corrugated pipe to compress or stretch; fluid in the valve rod and a valve cavity can be fully separated via the corrugated pipe and the reliable weld between the corrugated pipe and the valve rod, so an external leakage source can be prevented and afluid leakage channel can be cut off; corrugated pipe material with high mechanism strength is selected; and a waveform of the corrugated pipe is in a single U-shaped corrugated structure.
