流量控制閥

功用:通過(guò)改變閥口過(guò)流面積來(lái)調(diào)節(jié)輸出流量，從而控制執(zhí)行元件的運(yùn)動(dòng)速度。

分類:節(jié)流閥、調(diào)速閥、溫度補(bǔ)償調(diào)速閥、分流集流閥。

常用節(jié)流口結(jié)構(gòu)有錐形、三角槽形、矩形、三角形等。由節(jié)流方程知，當(dāng)壓力差.定時(shí)，改變開口面積即改變液阻就可改變流量。

節(jié)流閥實(shí)質(zhì)相當(dāng)于-一個(gè)可變節(jié)流口，借助控制機(jī)構(gòu)使閥芯相對(duì)于閥體孔運(yùn)動(dòng)改變閥口的過(guò)流面積。

結(jié)構(gòu)原理

主要零件有閥芯、閥體和螺母。閥體上右邊是進(jìn)油口，左邊是出油口。閥芯一端開有三角尖槽，另-端加工有螺紋，旋轉(zhuǎn)閥芯即可軸向移動(dòng)改變閥口過(guò)流面積。為平衡液壓徑向力，三角槽須對(duì)稱布置。

調(diào)速閥定差減壓閥與節(jié)流閥串聯(lián)而成，用來(lái)調(diào)節(jié)通過(guò)的流量自動(dòng)補(bǔ)

償負(fù)載變化的影響。

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

對(duì)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(dòng)作靈敏，過(guò)載能力大，噪聲小。

先導(dǎo)型溢流閥的導(dǎo)閥部分結(jié)構(gòu)尺寸較小，調(diào)壓彈簧不必很強(qiáng)，因此壓力調(diào)整比較輕便。但因先導(dǎo)型溢流閥要在先導(dǎo)閥和主閥都動(dòng)作后才能起控制作用，因此反應(yīng)不如直動(dòng)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(diǎn)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(jiǎn)單，加工和裝配方便。②過(guò)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)。

電磁式煤氣安全切斷閥是城鎮(zhèn)工業(yè)煤氣及其他可燃?xì)怏w設(shè)備管路輸送系統(tǒng)中的附屬安全裝置，它通常安裝于系統(tǒng)的主管線上，與燃?xì)鈭?bào)警系統(tǒng)消防系統(tǒng)及其它智能報(bào)警控制系統(tǒng)等相連接，當(dāng)安全系統(tǒng)檢測(cè)到燃?xì)馐褂貌话踩珪r(shí)如泄漏超溫超壓等，可聯(lián)動(dòng)該電磁閥快讀切斷氣源，確保用氣安全。是焊接連接的閥門卸和重安裝都比較困難所以它的使用限于通常能長(zhǎng)期可靠地運(yùn)行或使用條件荷刻溫度較高的場(chǎng)合。

R983037982 DBDS10P1X/315直動(dòng)式溢流閥

DBD 型泄壓閥是直動(dòng)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(jí) 25 bar … 400 bar）或球閥 (4)（壓力等級(jí) 630 bar）和調(diào)節(jié)類型 (5) 組成。系統(tǒng)壓力可通過(guò)調(diào)節(jié)類型 (5) 進(jìn)行無(wú)級(jí)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(guò)彈簧 (2) 上設(shè)置的值，則提升閥 (3) 或球 (4) 會(huì)逆著彈簧 (2) 打開。現(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(gè)壓力范圍內(nèi)實(shí)現(xiàn)良好的壓力調(diào)節(jié)，整個(gè)壓力范圍分為7個(gè)壓力等級(jí)。一個(gè)壓力等級(jí)對(duì)應(yīng)于某個(gè)彈簧，用于可通過(guò)該彈簧設(shè)置的較大工作壓力。

 

 

注意事項(xiàng)：

• 調(diào)整類型 (5) 的構(gòu)造使其不會(huì)丟失。由于萬(wàn)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(dòng)（可移動(dòng)）。

• 壓力等級(jí)“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(fù)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。

換向閥可分為手動(dòng)換向閥、電磁換向閥、電液換向閥等。

又稱克里斯閥，閥門的一種，具有多向可調(diào)的通道，可適時(shí)改變流體流向。

工作時(shí)借著閥外的驅(qū)動(dòng)傳動(dòng)機(jī)構(gòu)轉(zhuǎn)動(dòng)驅(qū)動(dòng)軸，帶動(dòng)搖拐臂，啟動(dòng)閥板，使工作流體時(shí)而從左入口通向閥的下部出口，時(shí)而從右入口變換通向下部出口，實(shí)現(xiàn)了周期變換流向的目的。這種變換閥在石油、化工生產(chǎn)中有著廣泛的應(yīng)用，在合成氨造氣系統(tǒng)中較為常用。此外，換向閥還可作成閥瓣式的結(jié)構(gòu)，多用于較小流量的場(chǎng)合。工作時(shí)只需轉(zhuǎn)動(dòng)手輪通過(guò)閥瓣來(lái)變換工作流體的流向。
