功能(neng)簡介:

過濾調壓(ya)(ya)閥是用來做什么的(de)(de)?減壓(ya)(ya)的(de)(de)。氣(qi)(qi)動(dong)(dong)閥門(men)定位器是按力(li)(li)(li)平(ping)衡(heng)原理(li)設(she)計(ji)工(gong)(gong)作(zuo)(zuo)(zuo)的(de)(de)，其工(gong)(gong)作(zuo)(zuo)(zuo)原理(li)是按力(li)(li)(li)平(ping)衡(heng)原理(li)設(she)計(ji)和(he)工(gong)(gong)作(zuo)(zuo)(zuo)的(de)(de)。當通入波紋管(guan)的(de)(de)信(xin)(xin)號壓(ya)(ya)力(li)(li)(li)增加時(shi)，使杠(gang)桿2繞(rao)(rao)支(zhi)(zhi)點轉動(dong)(dong)，檔板靠近噴(pen)嘴，噴(pen)嘴背壓(ya)(ya)經放大器放大后，送(song)入薄(bo)膜執(zhi)行機構氣(qi)(qi)室，使閥桿向下移(yi)動(dong)(dong)，并(bing)(bing)帶動(dong)(dong)反饋(kui)桿(擺桿)繞(rao)(rao)支(zhi)(zhi)點轉動(dong)(dong)，連(lian)接(jie)在(zai)同一(yi)軸上(shang)的(de)(de)反饋(kui)凸(tu)輪(偏心凸(tu)輪)也跟著作(zuo)(zuo)(zuo)逆時(shi)針方向轉動(dong)(dong)，通過滾輪使杠(gang)桿1繞(rao)(rao)支(zhi)(zhi)點轉動(dong)(dong)，并(bing)(bing)將反饋(kui)彈(dan)(dan)簧拉伸、彈(dan)(dan)簧對(dui)杠(gang)桿2的(de)(de)拉力(li)(li)(li)與信(xin)(xin)號壓(ya)(ya)力(li)(li)(li)作(zuo)(zuo)(zuo)用在(zai)波紋管(guan)上(shang)的(de)(de)力(li)(li)(li)達到力(li)(li)(li)矩平(ping)衡(heng)時(shi)儀表達到平(ping)衡(heng)狀態。此(ci)時(shi)，一(yi)定的(de)(de)信(xin)(xin)號壓(ya)(ya)力(li)(li)(li)就與一(yi)定的(de)(de)閥門(men)位置(zhi)相對(dui)應。以上(shang)作(zuo)(zuo)(zuo)用方式為正作(zuo)(zuo)(zuo)用，若要改變作(zuo)(zuo)(zuo)用方式，只要將凸(tu)輪翻轉，A向變成B向等，即(ji)可。

低壓(ya)(ya)(ya)大(da)流(liu)量減壓(ya)(ya)(ya)閥:PL系列低壓(ya)(ya)(ya)大(da)流(liu)量減壓(ya)(ya)(ya)閥，單級式膜片(pian)(pian)(pian)(pian)減壓(ya)(ya)(ya)結構，不銹(xiu)鋼膜片(pian)(pian)(pian)(pian)壓(ya)(ya)(ya)力(li)傳(chuan)輸(shu)，輸(shu)出穩定，主要應用于(yu)低壓(ya)(ya)(ya)大(da)流(liu)量氣(qi)(qi)(qi)(qi)(qi)(qi)體系統;特(te)點，大(da)直(zhi)徑(jing)波紋膜片(pian)(pian)(pian)(pian)提高了(le)壓(ya)(ya)(ya)力(li)靈敏度;金屬-金屬膜片(pian)(pian)(pian)(pian)密封(feng);大(da)流(liu)量，最小(xiao)化的(de)壓(ya)(ya)(ya)力(li)降;可選擇面板(ban)安裝(zhuang)。調(diao)壓(ya)(ya)(ya)閥的(de)原理(li)是利用了(le)彈(dan)(dan)簧力(li)與壓(ya)(ya)(ya)力(li)相平衡的(de)原理(li)，當彈(dan)(dan)簧的(de)壓(ya)(ya)(ya)力(li)小(xiao)于(yu)氣(qi)(qi)(qi)(qi)(qi)(qi)壓(ya)(ya)(ya)的(de)時(shi)(shi)候(hou)閥關閉(bi)，當壓(ya)(ya)(ya)力(li)大(da)于(yu)彈(dan)(dan)簧的(de)彈(dan)(dan)力(li)時(shi)(shi)候(hou)橡膠調(diao)壓(ya)(ya)(ya)膜片(pian)(pian)(pian)(pian)下方的(de)壓(ya)(ya)(ya)縮(suo)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)對膜片(pian)(pian)(pian)(pian)的(de)作用力(li)，推動膜片(pian)(pian)(pian)(pian)向(xiang)上(shang)拱曲離開閥座而(er)使空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)流(liu)入(ru)(ru)氣(qi)(qi)(qi)(qi)(qi)(qi)腔，此時(shi)(shi)卸荷(he)活塞在氣(qi)(qi)(qi)(qi)(qi)(qi)壓(ya)(ya)(ya)作用下移(yi)動，將排放(fang)閥門推離閥座，于(yu)是由(you)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)充入(ru)(ru)氣(qi)(qi)(qi)(qi)(qi)(qi)腔的(de)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)便通(tong)過排放(fang)閥和排氣(qi)(qi)(qi)(qi)(qi)(qi)口排入(ru)(ru)大(da)氣(qi)(qi)(qi)(qi)(qi)(qi)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)空(kong)轉。
