自作用(yong)減壓器是(shi)(shi)簡單的控(kong)(kong)制(zhi)(zhi)(zhi)閥(fa)，提供(gong)精確的控(kong)(kong)制(zhi)(zhi)(zhi)，同時(shi)易于安裝和維護。它們控(kong)(kong)制(zhi)(zhi)(zhi)閥(fa)門(men)下游的壓力，而不需(xu)要氣動或電氣控(kong)(kong)制(zhi)(zhi)(zhi)元件(jian)。DM 152減壓閥(fa)是(shi)(shi)一(yi)種膜片控(kong)(kong)制(zhi)(zhi)(zhi)的彈簧加載比例(li)控(kong)(kong)制(zhi)(zhi)(zhi)閥(fa)，主要用(yong)于食(shi)品加工(gong)和制(zhi)(zhi)(zhi)藥行(xing)業的衛生(sheng)應(ying)用(yong)。PTFE保護膜使隔膜在生(sheng)理上安全，蒸(zheng)汽溫度高達180°C。閥(fa)錐配有金屬密封。該閥(fa)門(men)不需(xu)要外(wai)部(bu)先導管路(lu)。

該(gai)閥(fa)門(men)(men)(men)采用深拉(la)不銹鋼(gang)制(zhi)(zhi)造(zao)，具(ju)有優(you)異(yi)的耐腐蝕性(xing)。它幾乎沒有盲區(qu)，適用于(yu)(yu)CIP和(he)SIP系統。傾(qing)斜設計允許完全排水。彈(dan)(dan)簧模(mo)塊包括彈(dan)(dan)簧帽(mao)，彈(dan)(dan)簧，調(diao)(diao)節螺(luo)釘(ding)(ding)，隔(ge)膜(mo)和(he)內部部件(jian)，僅通過(guo)(guo)夾緊(jin)環和(he)兩個螺(luo)栓(shuan)連接到(dao)閥(fa)體。在不同的控(kong)(kong)(kong)制(zhi)(zhi)壓(ya)(ya)力(li)范圍內更(geng)換隔(ge)膜(mo)或整個彈(dan)(dan)簧組件(jian)非常簡單，不需要(yao)特殊工具(ju)。這(zhe)同樣適用于(yu)(yu)維修和(he)保養(yang)。更(geng)改(gai)控(kong)(kong)(kong)制(zhi)(zhi)壓(ya)(ya)力(li)設置(zhi)不會影響閥(fa)門(men)(men)(men)的高(gao)度（非上(shang)升調(diao)(diao)整螺(luo)釘(ding)(ding)）。待控(kong)(kong)(kong)制(zhi)(zhi)的出(chu)口(kou)(kou)壓(ya)(ya)力(li)通過(guo)(guo)閥(fa)門(men)(men)(men)彈(dan)(dan)簧的力(li)（設定壓(ya)(ya)力(li)）在控(kong)(kong)(kong)制(zhi)(zhi)單元上(shang)平衡。當出(chu)口(kou)(kou)壓(ya)(ya)力(li)上(shang)升到(dao)高(gao)于(yu)(yu)使用調(diao)(diao)節螺(luo)釘(ding)(ding)設定的壓(ya)(ya)力(li)時，閥(fa)錐向(xiang)閥(fa)座移動并且介質的體積減小。隨著出(chu)口(kou)(kou)壓(ya)(ya)力(li)下降(jiang)，閥(fa)門(men)(men)(men)控(kong)(kong)(kong)制(zhi)(zhi)孔口(kou)(kou)增加;當管道減壓(ya)(ya)時，閥(fa)門(men)(men)(men)打開(kai)。順時針旋轉調(diao)(diao)節螺(luo)釘(ding)(ding)會增加出(chu)口(kou)(kou)壓(ya)(ya)力(li)。這(zhe)些閥(fa)門(men)(men)(men)沒有關(guan)閉(bi)元件(jian)，確保閥(fa)門(men)(men)(men)緊(jin)密關(guan)閉(bi)。
