ARGO-HYTOS比例方向控制閥功能特點(diǎn)
ARGO-HYTOS比例方向控制閥的閥門開度與輸入信號(hào)成比例地控制,并且由位置傳感器調(diào)節(jié)的比例方向閥控制。 比例方向控制閥適用于控制系統(tǒng)和控制電路。 比例方向閥可與車載電子設(shè)備一起使用。 對(duì)于沒有這些電子設(shè)備的比例方向閥,可以使用不同的外部控制電子設(shè)備。 比例減壓閥與輸入信號(hào)成比例地控制系統(tǒng)中的大壓力。 比例減壓閥控制二次壓力。 比例減壓閥和比例減壓閥可用作直接或先導(dǎo)閥。 雙向壓力補(bǔ)償器和三通壓力補(bǔ)償器可保持壓降恒定,并作為夾層閥配備集成的LS轉(zhuǎn)換閥。
ARGO-HYTOS電磁閥是用電磁控制的工業(yè)設(shè)備,是用來(lái)控制流體的自動(dòng)化基礎(chǔ)元件,屬于執(zhí)行器,并不限于液壓、氣動(dòng)。用在工業(yè)控制系統(tǒng)中調(diào)整介質(zhì)的方向、流量、速度和其他的參數(shù)。電磁閥可以配合不同的電路來(lái)實(shí)現(xiàn)預(yù)期的控制,而控制的精度和靈活性都能夠保證。電磁閥有很多種,不同的電磁閥在控制系統(tǒng)的不同位置發(fā)揮作用,常用的是單向閥、安全閥、方向控制閥、速度調(diào)節(jié)閥等。在實(shí)際應(yīng)用中,可根據(jù)不同的需要將方向控制閥分成若干類別:
(1)按照氣體在管道的流動(dòng)方向,如果只允許氣體向一個(gè)方向流動(dòng),這樣的閥叫做單向型控制閥,比如單向閥,梭閥等;可以改變氣體流向的控制閥叫做換向閥,比如常用的2way2port,2way3port,2way5port,3way5port等。
(2)按照控制方式可分為電磁閥,機(jī)械閥,氣控閥,人控閥。其中電磁閥又可以分為單和雙電控閥兩種;機(jī)械閥可分為球頭閥,滾輪閥等多種;氣控閥也可分為單氣控和雙氣控閥;人力閥 可以分為手動(dòng)閥,腳踏閥兩種。
(3)按工作原理可以分為直動(dòng)閥和先導(dǎo)閥,直動(dòng)閥就是靠人力或者電磁力,氣動(dòng)力直接實(shí)現(xiàn)換向要求的閥;先導(dǎo)閥是由先導(dǎo)頭和閥主體2部分構(gòu)成,有先導(dǎo)頭活塞驅(qū)動(dòng)閥主體里面的閥桿實(shí)現(xiàn)換向。
ARGO-HYTOS比例方向控制閥功能特點(diǎn)
The valve opening of the proportional directional control valves is controlled in proportion to the input signal and at the proportional directional valve regulated by a position sensor. Proportional directional control valves are suitable for use in control systems and control circuits. Proportional directional valves are available with on board electronics. For proportional directional valves without these electronics, there are different, external control electronics available. Proportional pressure relief valves control the maximum pressure in the system in proportion to the input signal. Proportional pressure reducing valves control the secondary pressure. Proportional pressure reducing valves and proportional pressure relief valves are available as direct or pilot operated valves. The 2-way pressure compensators and 3-way pressure compensators keep the pressure drop constant and are as sandwich valves equipped with integrated LS change-over valve.
