*SMC電氣比例閥VEF系列,SMC電磁閥原理

簡要描述：*SMC電氣比例閥VEF系列,SMC電磁閥原理
SMC電(dian)(dian)氣比例閥(fa)(fa)(fa)基(ji)于電(dian)(dian)磁(ci)開(kai)關閥(fa)(fa)(fa)的原理：斷電(dian)(dian)時(shi)，彈(dan)簧將鐵(tie)(tie)心直接壓(ya)在(zai)閥(fa)(fa)(fa)座上，使(shi)閥(fa)(fa)(fa)門關閉(bi)。線(xian)圈(quan)通(tong)電(dian)(dian)時(shi)，所產生電(dian)(dian)磁(ci)力(li)克服(fu)彈(dan)簧力(li)將鐵(tie)(tie)心提起(qi)，從而打開(kai)閥(fa)(fa)(fa)門。比例電(dian)(dian)磁(ci)閥(fa)(fa)(fa)對電(dian)(dian)磁(ci)開(kai)關閥(fa)(fa)(fa)的結構作了一些改動：在(zai)任(ren)何線(xian)圈(quan)電(dian)(dian)流下(xia)，使(shi)彈(dan)簧力(li)與(yu)電(dian)(dian)磁(ci)力(li)之間產生平衡。

SMC電氣比(bi)例閥工作(zuo)原理：

SMC電(dian)氣比例閥(fa)(fa)(fa)基于電(dian)磁(ci)(ci)開(kai)(kai)(kai)關(guan)閥(fa)(fa)(fa)的(de)(de)原(yuan)理：斷電(dian)時，彈(dan)簧(huang)將(jiang)(jiang)鐵心(xin)直接(jie)壓(ya)在閥(fa)(fa)(fa)座(zuo)上，使(shi)閥(fa)(fa)(fa)門(men)(men)(men)關(guan)閉。線(xian)(xian)圈(quan)(quan)通電(dian)時，所產生電(dian)磁(ci)(ci)力(li)克服彈(dan)簧(huang)力(li)將(jiang)(jiang)鐵心(xin)提起(qi)，從而打(da)開(kai)(kai)(kai)閥(fa)(fa)(fa)門(men)(men)(men)。比例電(dian)磁(ci)(ci)閥(fa)(fa)(fa)對電(dian)磁(ci)(ci)開(kai)(kai)(kai)關(guan)閥(fa)(fa)(fa)的(de)(de)結構作了(le)一些改動：在任何線(xian)(xian)圈(quan)(quan)電(dian)流下，使(shi)彈(dan)簧(huang)力(li)與(yu)(yu)電(dian)磁(ci)(ci)力(li)之間(jian)產生平衡(heng)。線(xian)(xian)圈(quan)(quan)電(dian)流的(de)(de)大(da)小或(huo)電(dian)磁(ci)(ci)力(li)的(de)(de)大(da)小將(jiang)(jiang)影響柱塞的(de)(de)行程和(he)閥(fa)(fa)(fa)門(men)(men)(men)開(kai)(kai)(kai)度(du)，而閥(fa)(fa)(fa)門(men)(men)(men)開(kai)(kai)(kai)度(du)(流量)與(yu)(yu)線(xian)(xian)圈(quan)(quan)電(dian)流(控(kong)制信號)之間(jian)為理想的(de)(de)線(xian)(xian)性(xing)關(guan)系(xi)。

SMC電(dian)(dian)氣(qi)(qi)比(bi)例(li)閥的功能(neng)分(fen)(fen)為(wei)(wei)信(xin)(xin)(xin)號(hao)(hao)傳(chuan)(chuan)遞和執行(xing)(xing)(xing)機構兩部(bu)分(fen)(fen)，壓縮氣(qi)(qi)體(ti)克服(fu)彈簧力使(shi)活(huo)塞向下運動可(ke)看(kan)作(zuo)是(shi)信(xin)(xin)(xin)號(hao)(hao)積(ji)累傳(chuan)(chuan)遞階段，活(huo)塞向下運動打開(kai)卸荷接(jie)(jie)口可(ke)看(kan)作(zuo)是(shi)執行(xing)(xing)(xing)階段。根據以上思路，可(ke)將(jiang)(jiang)(jiang)改造方案定為(wei)(wei)信(xin)(xin)(xin)號(hao)(hao)取(qu)樣、接(jie)(jie)收放(fang)大、執行(xing)(xing)(xing)元件三部(bu)分(fen)(fen)組成(cheng)。為(wei)(wei)此(ci)，信(xin)(xin)(xin)號(hao)(hao)取(qu)樣部(bu)分(fen)(fen)選用(yong)(yong)YX100型電(dian)(dian)接(jie)(jie)點(dian)(dian)壓力表(biao)（壓力0～1MPa，線(xian)圈(quan)電(dian)(dian)壓為(wei)(wei)交(jiao)流(liu)(liu)220V ），用(yong)(yong)這種(zhong)表(biao)的常(chang)(chang)開(kai)觸點(dian)(dian)采取(qu)卸荷信(xin)(xin)(xin)號(hao)(hao)，用(yong)(yong)常(chang)(chang)閉觸點(dian)(dian)采取(qu)加載信(xin)(xin)(xin)號(hao)(hao)，同時將(jiang)(jiang)(jiang)信(xin)(xin)(xin)號(hao)(hao)傳(chuan)(chuan)遞給接(jie)(jie)收放(fang)大部(bu)分(fen)(fen)，信(xin)(xin)(xin)號(hao)(hao)接(jie)(jie)收放(fang)大部(bu)分(fen)(fen)選用(yong)(yong)JZ7- 44型中(zhong)間繼電(dian)(dian)器(qi)（線(xian)圈(quan)電(dian)(dian)壓為(wei)(wei)交(jiao)流(liu)(liu)220V），用(yong)(yong)來接(jie)(jie)收電(dian)(dian)接(jie)(jie)點(dian)(dian)壓力表(biao)傳(chuan)(chuan)來的電(dian)(dian)信(xin)(xin)(xin)號(hao)(hao)并將(jiang)(jiang)(jiang)信(xin)(xin)(xin)號(hao)(hao)放(fang)大后傳(chuan)(chuan)遞給執行(xing)(xing)(xing)元件，執行(xing)(xing)(xing)元件選用(yong)(yong)23JVD一(yi)L3一(yi)X1型二(er)位三通單電(dian)(dian)控常(chang)(chang)閉截止式(shi)電(dian)(dian)磁閥（線(xian)圈(quan)電(dian)(dian)壓為(wei)(wei)交(jiao)流(liu)(liu)220V），用(yong)(yong)來接(jie)(jie)收中(zhong)間繼電(dian)(dian)器(qi)傳(chuan)(chuan)來的電(dian)(dian)信(xin)(xin)(xin)號(hao)(hao)并開(kai)啟截止閥，將(jiang)(jiang)(jiang)壓縮空氣(qi)(qi)送至卸荷器(qi)。
