長(zhǎng)期供應(yīng)REXROTH直動(dòng)式減壓閥ZDR
力士樂(lè)減壓閥的構(gòu)造類(lèi)型很多,以往常見(jiàn)的有薄膜式、內(nèi)彈簧活塞式等。減壓閥的基本作用原理是靠閥內(nèi)流道對(duì)水流的局部阻力降低水壓,水壓降的范圍由連接閥瓣的薄膜或活塞兩側(cè)的進(jìn)出口水壓差自動(dòng)調(diào)節(jié)。
德國(guó)REXROTH力士樂(lè)減壓閥是通過(guò)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(mén)。從流體力學(xué)的觀(guān)點(diǎn)看,REXROTH力士樂(lè)減壓閥是一個(gè)局部阻力可以變化的節(jié)流元件,即通過(guò)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。
Rexroth直動(dòng)式減壓閥為直動(dòng)式帶溢流閥的減壓閥(簡(jiǎn)稱(chēng)溢流減壓閥)。壓力為P1的壓縮空氣,由左端輸入經(jīng)閥口節(jié)流后,壓力降為P2輸出。P2的大小可由調(diào)壓彈簧進(jìn)行調(diào)節(jié)。順時(shí)針旋轉(zhuǎn)旋鈕,壓縮彈簧及膜片使閥芯下移,增大閥口的開(kāi)度使P2增大。若反時(shí)針旋轉(zhuǎn)旋鈕,閥口的開(kāi)度減小,P2隨之減小。
若P1瞬時(shí)升高,P2將隨之升高,使膜片氣室內(nèi)壓力升高,在膜片上產(chǎn)生的推力相應(yīng)增大,此推力破壞了原來(lái)力的平衡,使膜片向上移動(dòng),有少部分氣流經(jīng)溢流孔、排氣孔排出。在膜片上移的同時(shí),因復(fù)位彈簧的作用,使閥芯8也向上移動(dòng),關(guān)小進(jìn)氣閥口,節(jié)流作用加大,使輸出壓力下降,直至達(dá)到新的平衡為止,輸出壓力基本又回到原來(lái)值。若輸入壓力瞬時(shí)下降,輸出壓力也下降、膜片下移,閥芯隨之下移,進(jìn)氣閥口開(kāi)大,節(jié)流作用減小,使輸出壓力也基本回到原來(lái)值。逆時(shí)針旋轉(zhuǎn)旋鈕。使調(diào)節(jié)彈簧放松,氣體作用在膜片上的推力大于調(diào)壓彈簧的作用力,膜片向上曲,靠復(fù)位彈簧的作用關(guān)閉進(jìn)氣閥口。再旋轉(zhuǎn)旋鈕,進(jìn)氣閥芯的頂端與溢流閥座4將脫開(kāi),膜片氣室中的壓縮空氣便經(jīng)溢流孔、排氣孔11排出,使閥處于無(wú)輸出狀態(tài)。
