不锈(xiu)钢减压阀的(de)定值器：

1.不锈钢(gang)减压(ya)(ya)(ya)(ya)(ya)阀的定(ding)值(zhi)器是一种(zhong)高精度的减压(ya)(ya)(ya)(ya)(ya)阀，主要用于(yu)压(ya)(ya)(ya)(ya)(ya)力定(ding)值(zhi)。目前有两种(zhong)压(ya)(ya)(ya)(ya)(ya)力规(gui)格的定(ding)值(zhi)器：其气(qi)源压(ya)(ya)(ya)(ya)(ya)力分别为0．14MPa和0．35MPa，输(shu)出压(ya)(ya)(ya)(ya)(ya)力范(fan)围分别为0—0．1MPa和0一0．25MPa。其输(shu)出压(ya)(ya)(ya)(ya)(ya)力波动(dong)(dong)(dong)不大于(yu)最大输(shu)出压(ya)(ya)(ya)(ya)(ya)力的1%，常用于(yu)需(xu)要供给精确气(qi)源压(ya)(ya)(ya)(ya)(ya)力和信号压(ya)(ya)(ya)(ya)(ya)力的场合(he)，如气(qi)动(dong)(dong)(dong)实验设备、气(qi)动(dong)(dong)(dong)自动(dong)(dong)(dong)装(zhuang)置等。

2.不锈(xiu)钢(gang)减压(ya)阀(fa)(fa)的(de)(de)(de)定(ding)值器处于(yu)(yu)非(fei)工(gong)(gong)作(zuo)(zuo)状态时(shi)，由(you)(you)气(qi)源(yuan)输(shu)入的(de)(de)(de)压(ya)缩空(kong)气(qi)经过滤(lv)器1过滤(lv)后进(jin)入A室(shi)和正室(shi)。主阀(fa)(fa)芯(xin)19在弹簧(huang)20和气(qi)源(yuan)压(ya)力(li)作(zuo)(zuo)用(yong)下(xia)压(ya)在阀(fa)(fa)座(zuo)上，使(shi)A室(shi)与(yu)B室(shi)断开(kai)。进(jin)入A室(shi)的(de)(de)(de)气(qi)流经由(you)(you)阀(fa)(fa)口(kou)(又(you)称为活门(men))12至F室(shi)，再通(tong)过恒(heng)节流孔(kong)13降压(ya)后，分别进(jin)入G室(shi)和D室(shi)。由(you)(you)于(yu)(yu)这时(shi)尚未对膜(mo)片(pian)8加(jia)力(li)，挡(dang)板(ban)5与(yu)喷(pen)嘴(zui)4之间的(de)(de)(de)间距较(jiao)大，气(qi)体从(cong)喷(pen)嘴(zui)4流出(chu)(chu)(chu)时(shi)的(de)(de)(de)气(qi)流阻力(li)较(jiao)小，G室(shi)及(ji)D室(shi)的(de)(de)(de)气(qi)压(ya)较(jiao)低，膜(mo)片(pian)3及(ji)15保持原始位置(zhi)。进(jin)入只室(shi)的(de)(de)(de)微(wei)量(liang)气(qi)体主要(yao)经B室(shi)通(tong)过阀(fa)(fa)口(kou)2从(cong)排(pai)(pai)气(qi)口(kou)排(pai)(pai)出(chu)(chu)(chu)；另有(you)一(yi)部分从(cong)输(shu)出(chu)(chu)(chu)口(kou)排(pai)(pai)空(kong)。此(ci)时(shi)输(shu)出(chu)(chu)(chu)口(kou)无(wu)气(qi)流输(shu)出(chu)(chu)(chu)，由(you)(you)喷(pen)嘴(zui)流出(chu)(chu)(chu)而排(pai)(pai)空(kong)微(wei)量(liang)气(qi)体是维持喷(pen)嘴(zui)挡(dang)板(ban)装置(zhi)工(gong)(gong)作(zuo)(zuo)所(suo)必须的(de)(de)(de)，因其(qi)为无(wu)功耗(hao)气(qi)量(liang)，所(suo)以希望其(qi)耗(hao)量(liang)越(yue)小越(yue)好。
