REXROTH力士(shi)樂(le)減(jian)(jian)壓(ya)閥直(zhi)(zhi)接作用式(shi)減(jian)(jian)壓(ya)閥，帶有平膜片或波紋管(guan)。因為它是(shi)獨立結(jie)構，因此(ci)無需在下游安(an)裝外部傳感線。它是(shi)三種(zhong)減(jian)(jian)壓(ya)閥中體積最小、使用的(de)(de)一種(zhong)，專為中低(di)流量設計。直(zhi)(zhi)接作用式(shi)減(jian)(jian)壓(ya)閥的(de)(de)精確(que)度(du)通常為下游設定(ding)點的(de)(de)+/-10%。

當減(jian)(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)的(de)(de)輸(shu)出壓(ya)(ya)(ya)(ya)力(li)較(jiao)高(gao)或(huo)通徑較(jiao)大(da)時(shi)，用調壓(ya)(ya)(ya)(ya)彈(dan)簧直(zhi)(zhi)接調壓(ya)(ya)(ya)(ya)，則(ze)彈(dan)簧剛度必然過大(da)，流(liu)量變(bian)(bian)化(hua)時(shi)，輸(shu)出壓(ya)(ya)(ya)(ya)力(li)波動(dong)較(jiao)大(da)，閥(fa)(fa)(fa)(fa)(fa)的(de)(de)結構尺寸(cun)也將(jiang)增大(da)。為(wei)了(le)(le)克服這些缺(que)點，可采用先(xian)(xian)導式減(jian)(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)。先(xian)(xian)導式減(jian)(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)的(de)(de)工作原理與直(zhi)(zhi)動(dong)式的(de)(de)基本相同。先(xian)(xian)導式減(jian)(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)所(suo)用的(de)(de)調壓(ya)(ya)(ya)(ya)氣體(ti)，是由小(xiao)型(xing)的(de)(de)直(zhi)(zhi)動(dong)式減(jian)(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)供給的(de)(de)。若把小(xiao)型(xing)直(zhi)(zhi)動(dong)式減(jian)(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)裝(zhuang)在閥(fa)(fa)(fa)(fa)(fa)體(ti)內(nei)部(bu)，則(ze)稱(cheng)為(wei)內(nei)部(bu)先(xian)(xian)導式減(jian)(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)；若將(jiang)小(xiao)型(xing)直(zhi)(zhi)動(dong)式減(jian)(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)裝(zhuang)在主閥(fa)(fa)(fa)(fa)(fa)體(ti)外(wai)部(bu)，則(ze)稱(cheng)為(wei)外(wai)部(bu)先(xian)(xian)導式減(jian)(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)。與直(zhi)(zhi)動(dong)式減(jian)(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)相比，增加了(le)(le)由噴(pen)(pen)嘴4、擋(dang)板(ban)3、固定節流(liu)孔(kong)9及氣室B所(suo)組成(cheng)的(de)(de)噴(pen)(pen)嘴擋(dang)板(ban)放大(da)環節。當噴(pen)(pen)嘴與擋(dang)板(ban)之(zhi)間(jian)的(de)(de)距離發生微小(xiao)變(bian)(bian)化(hua)時(shi)，就會使B室中的(de)(de)壓(ya)(ya)(ya)(ya)力(li)發生根明顯(xian)的(de)(de)變(bian)(bian)化(hua)，從而引(yin)起膜片10有較(jiao)大(da)的(de)(de)位移，去控制閥(fa)(fa)(fa)(fa)(fa)芯(xin)6的(de)(de)上下移動(dong)，使進氣閥(fa)(fa)(fa)(fa)(fa)口8開大(da)或(huo)關小(xiao)、提高(gao)了(le)(le)對閥(fa)(fa)(fa)(fa)(fa)芯(xin)控制的(de)(de)靈(ling)敏度，即(ji)提高(gao)了(le)(le)穩壓(ya)(ya)(ya)(ya)精度。

在(zai)主閥(fa)(fa)體外部還有一個小型(xing)直(zhi)動式減壓(ya)閥(fa)(fa)由它來控制主閥(fa)(fa)。此類閥(fa)(fa)適于通徑(jing)在(zai)20mm以上，遠距離(30m以內)、高處、危險處、調(diao)壓(ya)困(kun)難的場合。

REXROTH力士樂減壓閥性能(neng)：

(1)調(diao)壓范圍：它是指減壓閥輸出壓力P2的可調(diao)范圍，在此范圍內要(yao)求達到規(gui)定的精度(du)。調(diao)壓范圍主要(yao)與調(diao)壓彈簧的剛(gang)度(du)有關(guan)。

(2)壓(ya)力(li)(li)(li)(li)特性：它是指流量(liang)g為定值(zhi)時(shi)，因輸(shu)(shu)入壓(ya)力(li)(li)(li)(li)波(bo)動而(er)引起輸(shu)(shu)出(chu)壓(ya)力(li)(li)(li)(li)波(bo)動的特性。輸(shu)(shu)出(chu)壓(ya)力(li)(li)(li)(li)波(bo)動越小(xiao)，減壓(ya)閥的特性越好。輸(shu)(shu)出(chu)壓(ya)力(li)(li)(li)(li)必須低于(yu)輸(shu)(shu)入壓(ya)力(li)(li)(li)(li)—定值(zhi)才基本上(shang)不隨輸(shu)(shu)入壓(ya)力(li)(li)(li)(li)變化而(er)變化。

(3)流(liu)量特(te)性(xing)：它是指輸(shu)入壓(ya)力(li)—定(ding)時，輸(shu)出(chu)壓(ya)力(li)隨輸(shu)出(chu)流(liu)量g的變(bian)(bian)(bian)化而變(bian)(bian)(bian)化的持性(xing)。當流(liu)量g發生變(bian)(bian)(bian)化時，輸(shu)出(chu)壓(ya)力(li)的變(bian)(bian)(bian)化越(yue)小越(yue)好。一般輸(shu)出(chu)壓(ya)力(li)越(yue)低，它隨輸(shu)出(chu)流(liu)量的變(bian)(bian)(bian)化波動就越(yue)小。

REXROTH力士樂減壓(ya)閥(fa)它(ta)可將閥(fa)前(qian)管路較高的(de)液體壓(ya)力減少至閥(fa)后(hou)管路所需的(de)水(shui)平。這(zhe)里的(de)傳輸介質主(zhu)要是水(shui)。減壓(ya)閥(fa)廣泛(fan)用(yong)于(yu)高層建筑、城市給(gei)水(shui)管網水(shui)壓(ya)過高的(de)區(qu)域、礦井及(ji)其他(ta)場合(he)，以保證給(gei)水(shui)系統(tong)(tong)(tong)中各(ge)用(yong)水(shui)點(dian)獲(huo)得適當的(de)服務水(shui)壓(ya)和(he)流量(liang)。鑒(jian)于(yu)水(shui)的(de)漏失率和(he)浪費(fei)程度幾乎(hu)同(tong)給(gei)水(shui)系統(tong)(tong)(tong)的(de)水(shui)壓(ya)大小成正比，因(yin)此減壓(ya)閥(fa)具(ju)有(you)改(gai)善系統(tong)(tong)(tong)運(yun)行工(gong)況和(he)潛在節水(shui)作(zuo)用(yong)，據統(tong)(tong)(tong)計(ji)其節水(shui)效果約為30%。

1、關(guan)閉減(jian)壓(ya)閥(fa)前的閘閥(fa)，開(kai)啟(qi)減(jian)壓(ya)閥(fa)后的閘閥(fa)，制造下(xia)游低壓(ya)環(huan)境；

2、將調節(jie)螺釘按(an)逆時(shi)針旋轉(zhuan)至最上位置（相(xiang)對低出口(kou)壓(ya)力），然后關閉減壓(ya)閥(fa)后閘閥(fa)；

3、慢慢開(kai)啟減壓閥(fa)前的(de)閘閥(fa)至全開(kai)；

4、順時(shi)針慢慢旋(xuan)轉調(diao)節螺釘(ding)，將出口壓力調(diao)至(zhi)所(suo)需要(yao)的壓力（以(yi)閥(fa)后(hou)表壓為準）；調(diao)整好后(hou)，將鎖緊

螺母(mu)鎖緊(jin)，打開減壓閥(fa)后閘閥(fa)；

5、如在調(diao)整時出口(kou)壓力高于(yu)設定壓力，須從第一(yi)步開始重(zhong)新(xin)調(diao)整，即只能(neng)從低壓向高壓調(diao)。
