4WMM6J6X/F-IN002手動(dòng)換向閥

特點(diǎn):

閥芯為錐閥，密封性能好，且動(dòng)作靈敏;

通流能力大，抗污染;

一閥多用，易組成各式系統(tǒng)，結(jié)構(gòu)緊湊。

特別對(duì)大流量及非礦物油介質(zhì)的場(chǎng)合，優(yōu)點(diǎn)更為突出。

插裝閥基本組件由閥芯、閥套、彈簀和密封圈組成。根據(jù)用途不同分為方向閥組件、壓力閥組件和流量閥組件。

二通閥

由一個(gè)二位三通電磁滑閥控制方向閥組件控制腔的通油方式，可組成二位二通閥。

三通閥

由兩個(gè)方向閥組件并聯(lián)而成，對(duì)外形成-一個(gè)壓力油口、-一個(gè)工作油口和一一個(gè)回油口。三通插裝閥的工作狀態(tài)數(shù)取決于先導(dǎo)換向閥的工作位置數(shù)。

四通閥由兩個(gè)三通閥并聯(lián)而成。

疊加閥以板式閥為基礎(chǔ)，每個(gè)疊加閥不僅起到單個(gè)閥的功能，而且還溝通閥與閥的流道。換向閥安裝在上方，對(duì)外連接油口開在下邊的底板上，其他的閥通過螺栓連接在換向閥和底板之間。

換向閥主要由閥體、密封組件、凸輪、閥桿、手柄和閥蓋等零部件組成(圖1)。閥門由手柄驅(qū)動(dòng)，通過手柄帶動(dòng)閥桿與凸輪旋轉(zhuǎn)，凸輪具有定位驅(qū)動(dòng)與鎖定密封組件的開啟與關(guān)閉功能。手柄逆時(shí)針旋轉(zhuǎn)，兩組密封組件分別在凸輪的作用下關(guān)閉下端的兩個(gè)通道，上端的兩個(gè)通道分別與管道裝置的進(jìn)口相通。反之，上端的兩個(gè)通道關(guān)閉，下端兩個(gè)通道與管道裝置的進(jìn)口相通，實(shí)現(xiàn)了不停車換向。

4WMM6J6X/F-IN002手動(dòng)換向閥

說明

WMM型手動(dòng)換向閥是通過手柄的轉(zhuǎn)動(dòng)使閥芯做軸向移動(dòng)從而對(duì)油路進(jìn)行切換的直動(dòng)式換向滑閥。具有二位三通，二位四通和三位四通多種滑閥機(jī)能。并可選擇定位設(shè)備和彈簧復(fù)位裝置，采用板式連接。

 WMM…/型（帶復(fù)位彈簧，不帶定位設(shè)備）：

該閥由閥體、手柄、閥芯、一個(gè)或兩個(gè)復(fù)位彈簧和推桿等組成。

當(dāng)未操縱手柄時(shí)，閥芯被復(fù)位彈簧保持在中位或初始位置上，當(dāng)向右或向左推動(dòng)手柄2時(shí)，手柄通過鉸鏈推動(dòng)推桿并直接控制閥芯，閥芯便移動(dòng)到要求的位置，從而獲得所需要的流動(dòng)截面。當(dāng)手柄回到零位時(shí)，控制閥芯借助復(fù)位彈簧回到正常位置。這種閥的切換位置由手柄操縱確定。

WMM…/F型（不帶復(fù)位彈簧，帶定位設(shè)備）：

原理上與WMM…/基本相同，但這種形式的閥是有二個(gè)或者三個(gè)切換位置和一個(gè)定位設(shè)備的控制閥。因而所有切換位置是固定的。

插裝阻尼器：

由于工作條件限制，切換過程中可能出現(xiàn)閥的流量超過閥性能曲線上規(guī)定的流量，這時(shí)需要采用阻尼器。它安裝在閥的P腔或油路中。

WMM閥采用板式連接。較國內(nèi)其它系統(tǒng)閥具有體積小，通流能力大，可靠性好等優(yōu)點(diǎn)，可與相同通徑的疊加閥使用。廣泛應(yīng)用于工程機(jī)械、煤礦機(jī)械、化工機(jī)械、輕工機(jī)械、機(jī)車等各行業(yè)中。

減壓閥是通過調(diào)節(jié)，將進(jìn)口壓力減至某一需要的出口壓力，并依靠介質(zhì)本身的能量，使出口壓力自動(dòng)保持穩(wěn)定的閥門。從流體力學(xué)的觀點(diǎn)看，減壓閥是一個(gè)局部阻力可以變化的節(jié)流元件，即通過改變節(jié)流面積，使流速及流體的動(dòng)能改變，造成不同的壓力損失，從而達(dá)到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié)，使閥后壓力的波動(dòng)與彈簧力相平衡，使閥后壓力在一定的誤差范圍內(nèi)保持恒定。
