壓力繼電器是利用液的壓力來(lái)啟閉電氣觸點(diǎn)的
液壓電氣轉(zhuǎn)換元件。當(dāng)系統(tǒng)壓力達(dá)到壓力繼電器的
調(diào)定值時(shí),發(fā)出電信號(hào),使電氣元件(如電磁鐵、電機(jī)、時(shí)間繼電器、電磁離合器等)動(dòng)作,使油路卸壓、換向,執(zhí)行元件實(shí)現(xiàn)順序動(dòng)作,
或關(guān)閉電動(dòng)機(jī)使系統(tǒng)停止工作,起安全保護(hù)作用等。
壓力繼電器有柱塞式、膜片式、彈簧管式和波紋管式四種結(jié)構(gòu)形式。
當(dāng)從繼電器下端進(jìn)油口3進(jìn)入的液體壓力達(dá)到調(diào)定壓力值時(shí),
推動(dòng)柱塞2上移,此位移通過(guò)杠桿放大后推動(dòng)微動(dòng)開(kāi)關(guān)4動(dòng)作。
改變彈簧1的壓縮量,可以調(diào)節(jié)繼電器的動(dòng)作壓力。
應(yīng)用場(chǎng)合:用于安全保護(hù)、控制執(zhí)行元件的順序動(dòng)作、用于泵的啟閉、用于泵的卸荷。
注意: 壓力繼電器必須放在壓力有明顯變化的地方才能輸出電信號(hào)。
若將壓力繼電器放在回油路上,由于回油路直接接回油箱,壓力也沒(méi)有變化,所以壓力繼電器也不會(huì)工作。

流量閥適用于需要進(jìn)行流量控制的水系統(tǒng)中,尤其適合于供熱,
空調(diào)等非腐蝕性液體介質(zhì)的流量控制;安裝流量閥在水系統(tǒng)中,
經(jīng)運(yùn)行前的一次調(diào)節(jié),即可使系統(tǒng)流量自動(dòng)恒定在要求的設(shè)定值。自動(dòng)消除水系統(tǒng)中因各種因素引起的水力失調(diào)現(xiàn)象,
保持用戶所需流量,克服“冷熱不均”提高供熱,空調(diào)的室溫,
提高系統(tǒng)能效,實(shí)現(xiàn)節(jié)能,是供熱、空調(diào)系統(tǒng)實(shí)現(xiàn)“計(jì)量收費(fèi)”的理想配套產(chǎn)品。

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。
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(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。
