脈沖閥膜(mo)片的使用：

垂鏈式膜(mo)(mo)片(pian)(pian)由(you)靠近邊緣處(chu)開槽的(de)圓板(ban)構成(cheng)(cheng)，其彈性應變主要發(fa)生在(zai)邊緣環(huan)形槽處(chu)，常用這種膜(mo)(mo)片(pian)(pian)壓(ya)縮(suo)應變管(guan)或(huo)柱來達到(dao)測壓(ya)目(mu)的(de)。垂鏈式膜(mo)(mo)片(pian)(pian)的(de)硬(ying)中心部分在(zai)受壓(ya)移(yi)動時接近平移(yi)，因此用于(yu)電容式傳感器或(huo)壓(ya)電式傳感器效果較好。波紋膜(mo)(mo)片(pian)(pian)壓(ya)有環(huan)狀(zhuang)同心波紋。為了增加膜(mo)(mo)片(pian)(pian)中心的(de)位移(yi)可把兩個(ge)膜(mo)(mo)片(pian)(pian)焊在(zai)一起(qi)制(zhi)成(cheng)(cheng)膜(mo)(mo)盒或(huo)進一步把數個(ge)膜(mo)(mo)盒串接成(cheng)(cheng)膜(mo)(mo)盒組。

脈沖閥膜(mo)片的簡介

圓形(xing)膜(mo)(mo)(mo)狀的彈性(xing)敏感元(yuan)件。當(dang)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)的兩面(mian)受到不(bu)同(tong)的壓(ya)力（或(huo)力）的作用(yong)時，膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)向壓(ya)力低(di)的一面(mian)應變移動，使其中(zhong)心(xin)(xin)產生與壓(ya)力差成關系的位移。膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)的形(xing)式(shi)主要有平(ping)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)、垂鏈式(shi)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)和波紋膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)三種(zhong)(zhong)。平(ping)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)又(you)可按周(zhou)邊(bian)是否固定(ding)(ding)支撐、中(zhong)心(xin)(xin)是否開孔以及膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)區域受力分布狀況的不(bu)同(tong)等分為多種(zhong)(zhong)形(xing)式(shi)，其中(zhong)最常用(yong)的是由周(zhou)邊(bian)固定(ding)(ding)的等截面(mian)圓形(xing)薄(bo)板構成的平(ping)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)。
