賀德克流量節(jié)流閥SR08-01-C-N-7.9H;節(jié)流閥(Choke valve)的外形結(jié)構(gòu)與截止閥并無(wú)區(qū)別，只是它們啟閉件的形狀有所不同。
節(jié)流閥的啟閉件大多為圓錐流線(xiàn)型，通過(guò)它改變通道截面積而達(dá)到調(diào)節(jié)流量和壓力。節(jié)流閥供在壓力降極大的情況下作降低介質(zhì)壓力之用。介質(zhì)在節(jié)流閥瓣和閥座之間流速很大，以致使這些零件表面很快損壞－即所謂氣蝕現(xiàn)象。為了盡量減少氣蝕影響，閥瓣采用耐氣蝕材料（合金鋼制造）并制成頂jian角為140～180的流線(xiàn)型圓錐體這還能使閥瓣能有較大的開(kāi)啟高度，一般不推薦在小縫隙下節(jié)流。由于節(jié)流閥的流量不僅取決于節(jié)流口面積的大小，還與節(jié)流口前后的壓差有關(guān)，閥的剛度小，
故只適用于執(zhí)行元件負(fù)載變化很小且速度穩(wěn)定性要求不高的場(chǎng)合。
對(duì)于執(zhí)行元件負(fù)載變化大及對(duì)速度穩(wěn)定性要求高的節(jié)流調(diào)速系統(tǒng)
，必須對(duì)節(jié)流閥進(jìn)行壓力補(bǔ)償來(lái)保持節(jié)流閥前后壓差不變，從而達(dá)到流量穩(wěn)定705787;DRVP-20-01.2;281

賀德克液控單向閥RV-40-01.1/0 液控單向閥是依靠控制流體壓力，可以使單向閥反向流通的閥。這種閥在煤礦機(jī)械的液壓支護(hù)設(shè)備中占有較重要的地位。液控單向閥與普通單向閥不同之處是多了一個(gè)控制油路K，當(dāng)控制油路未接通壓力油液時(shí)，液控單向閥就象普通單向閥一樣工作，壓力油只從進(jìn)油口流向出油口，不能反向流動(dòng)。當(dāng)控制油路有控制壓力輸入時(shí)，活塞頂桿在壓力油作用下向右移動(dòng)，用頂桿頂開(kāi)單向閥，使進(jìn)出油口接通。若出油口大于進(jìn)油口就能使油液反向流動(dòng)480221;DB4E-01X-200M200;68

賀德克液壓系統(tǒng)冷卻器OK-EL6S/3.1/M/A/1原理
手動(dòng)工作過(guò)程:濾水器接入管道系統(tǒng)后，水由下部進(jìn)水口進(jìn)入濾水器，當(dāng)水中雜質(zhì)通過(guò)網(wǎng)芯時(shí)，由于體積大于網(wǎng)芯孔，而衩截留在網(wǎng)芯上，當(dāng)聚積到一定數(shù)量時(shí)，即造成進(jìn)出水口產(chǎn)生一定壓差值。(濾網(wǎng)精度直徑不同壓差不同,一般為0.15Mpa)，手動(dòng)打開(kāi)排污閥門(mén)，排污開(kāi)始，轉(zhuǎn)動(dòng)手柄，旋轉(zhuǎn)方向分正反時(shí)針旋轉(zhuǎn)均可，每10秒--30秒轉(zhuǎn)動(dòng)一格，手柄指向每一個(gè)凹部固定，直至旋轉(zhuǎn)一圈，關(guān)閉排污閥，手動(dòng)排污完成。3047310 DB12P-01-C-N-050V
