特點應用:

在(zai)膜(mo)(mo)(mo)片(pian)(pian)(pian)5上(shang)產生的(de)(de)推力(li)(li)相(xiang)應增(zeng)大(da)(da)(da)，此推力(li)(li)破壞了原來力(li)(li)的(de)(de)平衡(heng)，使膜(mo)(mo)(mo)片(pian)(pian)(pian)5向上(shang)移動，有少部分氣(qi)(qi)(qi)流經溢(yi)流孔(kong)(kong)12、排氣(qi)(qi)(qi)孔(kong)(kong)11排出(chu)(chu)。在(zai)膜(mo)(mo)(mo)片(pian)(pian)(pian)上(shang)移的(de)(de)同時(shi)，因復(fu)位(wei)彈(dan)簧(huang)(huang)9的(de)(de)作(zuo)(zuo)(zuo)(zuo)用(yong)(yong)，使閥(fa)(fa)芯8也(ye)(ye)(ye)向上(shang)移動，關小進(jin)氣(qi)(qi)(qi)閥(fa)(fa)口(kou)(kou)10，節流作(zuo)(zuo)(zuo)(zuo)用(yong)(yong)加大(da)(da)(da)，使輸(shu)(shu)出(chu)(chu)壓(ya)(ya)力(li)(li)下(xia)降，直至達(da)到新的(de)(de)平衡(heng)為止，輸(shu)(shu)出(chu)(chu)壓(ya)(ya)力(li)(li)基本又(you)回到原來值(zhi)。若輸(shu)(shu)入壓(ya)(ya)力(li)(li)瞬(shun)時(shi)下(xia)降，輸(shu)(shu)出(chu)(chu)壓(ya)(ya)力(li)(li)也(ye)(ye)(ye)下(xia)降、膜(mo)(mo)(mo)片(pian)(pian)(pian)5下(xia)移，閥(fa)(fa)芯8隨之下(xia)移，進(jin)氣(qi)(qi)(qi)閥(fa)(fa)口(kou)(kou)10開(kai)大(da)(da)(da)，節流作(zuo)(zuo)(zuo)(zuo)用(yong)(yong)減小，使輸(shu)(shu)出(chu)(chu)壓(ya)(ya)力(li)(li)也(ye)(ye)(ye)基本回到原來值(zhi)。逆時(shi)針旋(xuan)(xuan)轉(zhuan)旋(xuan)(xuan)鈕1。使調節彈(dan)簧(huang)(huang)2、3放松，氣(qi)(qi)(qi)體作(zuo)(zuo)(zuo)(zuo)用(yong)(yong)在(zai)膜(mo)(mo)(mo)片(pian)(pian)(pian)5上(shang)的(de)(de)推力(li)(li)大(da)(da)(da)于(yu)調壓(ya)(ya)彈(dan)簧(huang)(huang)的(de)(de)作(zuo)(zuo)(zuo)(zuo)用(yong)(yong)力(li)(li)，膜(mo)(mo)(mo)片(pian)(pian)(pian)向上(shang)曲，靠復(fu)位(wei)彈(dan)簧(huang)(huang)的(de)(de)作(zuo)(zuo)(zuo)(zuo)用(yong)(yong)關閉進(jin)氣(qi)(qi)(qi)閥(fa)(fa)口(kou)(kou)10。再旋(xuan)(xuan)轉(zhuan)旋(xuan)(xuan)鈕1，進(jin)氣(qi)(qi)(qi)閥(fa)(fa)芯8的(de)(de)頂端(duan)與溢(yi)流閥(fa)(fa)座4將脫(tuo)開(kai)，膜(mo)(mo)(mo)片(pian)(pian)(pian)氣(qi)(qi)(qi)室6中(zhong)的(de)(de)壓(ya)(ya)縮空(kong)氣(qi)(qi)(qi)便經溢(yi)流孔(kong)(kong)12、排氣(qi)(qi)(qi)孔(kong)(kong)11排出(chu)(chu)，使閥(fa)(fa)處于(yu)無輸(shu)(shu)出(chu)(chu)狀態。
