DBDS6K1X/100直動式溢流閥

溢流閥一般有兩種結(jié)構(gòu)：1、直動型溢流閥 。2、先導式溢流閥。

對溢流閥的主要要求：調(diào)壓范圍大，調(diào)壓偏差小，壓力振擺小，動作靈敏，過載能力大，噪聲小。

先導型溢流閥的導閥部分結(jié)構(gòu)尺寸較小，調(diào)壓彈簧不必很強，因此壓力調(diào)整比較輕便。但因先導型溢流閥要在先導閥和主閥都動作后才能起控制作用，因此反應(yīng)不如直動型溢流閥靈敏。

與三節(jié)同心結(jié)構(gòu)相比，二節(jié)同心結(jié)構(gòu)的特點是：①主閥芯僅與閥套和主閥座有同心度要求，免去了與閥蓋的配合，故結(jié)構(gòu)簡單，加工和裝配方便。②過流面積大，在相同流量的情況下，主閥開啟高度小；或者在相同開啟高度的情況下，其通流能力大，因此，可做得體積小、重量輕。③主閥芯與閥套可以通用化，便于批量生產(chǎn)。

電磁閥線圈的額定電壓有DC12V、DC24V、AC24V（50/60Hz）、AC110V（50/60Hz）、AC220V（50/60Hz）、AC380V（50/60Hz）。一般在電氣設(shè)計時要么采用AC220V（不需加裝開關(guān)電源，成本低、線路簡單而便于維護）、要么采用DC24V（常用的的安全電壓、開關(guān)電源/電磁閥線圈都易于維修更換）。

檢測電磁閥好壞的方法：先給電磁閥通上被控制的介質(zhì)（帶壓力的液體、氣體<空氣>，壓力值為電磁閥使用壓力范圍的中間值），再給電磁閥線圈通電，如果被控制介質(zhì)有從通到斷或從斷到通的狀態(tài)的變化，那么電磁閥就是好的，否則就是有問題的。

DBDS6K1X/100直動式溢流閥

DBD 型泄壓閥是直動式座閥。它們用于限制系統(tǒng)壓力。

閥門主要由套筒 (1)、彈簧 (2)、帶阻尼活塞的提升閥 (3)（壓力等級 25 bar … 400 bar）或球閥 (4)（壓力等級 630 bar）和調(diào)節(jié)類型 (5) 組成。系統(tǒng)壓力可通過調(diào)節(jié)類型 (5) 進行無級設(shè)置。彈簧 (2) 將提升閥 (3) 或球 (4) 推到閥座上。通道 P 連接到系統(tǒng)。系統(tǒng)中存在的壓力作用在提升閥表面（或球體）上。如果通道 P 中的壓力超過彈簧 (2) 上設(shè)置的值，則提升閥 (3) 或球 (4) 會逆著彈簧 (2) 打開�，F(xiàn)在，液壓油從通道 P 流入通道 T。提升閥 (3) 的行程受到壓花 (6) 的限制。

為了在整個壓力范圍內(nèi)實現(xiàn)良好的壓力調(diào)節(jié)，整個壓力范圍分為7個壓力等級。一個壓力等級對應(yīng)于某個彈簧，用于可通過該彈簧設(shè)置的較大工作壓力。

注意事項：

調(diào)整類型 (5) 的構(gòu)造使其不會丟失。由于萬向節(jié)安裝，在完全卸載的情況下，調(diào)整類型 (5) 中的調(diào)整元件保持松動（可移動）。

壓力等級“25”：如果在完全卸載的調(diào)節(jié)類型下，較小壓力仍未穩(wěn)定，則由于彈簧和/或恢復力較低，調(diào)節(jié)元件必須“拉回”到止擋位置。

為了調(diào)整/增加壓力，然后可以再次擰入調(diào)整元件。

止回閥(Check Valve)：一般分為升降式、旋啟式、蝶式及臥式等四種類型。

升降式止回閥的結(jié)構(gòu)一般與截止閥相似，其閥瓣沿著通道中線作升降運動，動作可靠，但流體阻力較大，適用于較****的場合。升降式止回閥可分為直通式和立式兩種。直通式升降止回閥一般只能安裝在水平管路，而立式升降止回閥一般就安裝在垂直管路。
