I-HITORK I-valve yokulawula umoya iyingxenye ehlakaniphe kakhulu enqubweni yokukhiqiza.Kuhlelo lokulawula, i-valve yokulawula umoya izovela nakanjani ukungqubuzana.Ngakho-ke uyini umthelela wokungqubuzana kuma-valve okulawula umoya?
Ukunqoba ukungqubuzana kungomunye wemisebenzi eyinhloko ye-valve positioner.Ukungqubuzana kwe-valve elawulayo ikakhulukazi kuvela ezingxenyeni ezimbili: ukupakisha kanye nendandatho yophawu lwevalvu yemikhono.Uma isiqu singebushelelezi noma ukupakisha kuqinile kakhulu, ukungqubuzana phakathi kwesiqu nokupakisha kungaba ngokweqile.Ezikhathini zokushisa okuphezulu, ukufaniswa kokuphazamiseka kwendandatho yegraphite nomkhono kuvame ukusetshenziselwa ukwenza ivalvu elawulayo ihlangabezane nezidingo zokuvala umklamo.Uma ukuphazamiseka kukukhulu kakhulu noma i-sleeve ellipse inkulu kakhulu, ukungqubuzana phakathi kwe-spool nomkhono kukhulu kakhulu.Ngenxa yokuthi amandla okungqubuzana okumile makhulu kakhulu kunokungqubuzana okuguquguqukayo, ebangeni lohlu olukhulu lwesenzo, i-valve izogxuma, eyaziwa nangokuthi i-peristalsis.Indlela yayo yokuguquguquka ingokulandelayo: uma ukuguqulwa kwe-telesignal (okungukuthi isignali yesinyathelo) kwenzeka, ukuchezuka okunegethivu okubangelwa ukungqubuzana kukhulu kakhulu, futhi umphumela uwonke wesimeli ulokhu ukhulisa okukhiphayo.Lapho i-static friction force ikhuphuka ngokwanele ukunqoba, i-valve iyasebenza.Ngenxa yokuthi ukungqubuzana okumile kukhulu kunokungqubuzana okuguquguqukayo, i-valve overshoot, ukuchezuka okuyinegethivu kuba ukuchezuka okuhle.Kunzima ukusimamisa uhlelo ngenxa yokudubula okuphindaphindiwe.Behlose inkinga yokungqubuzana, abanye abakhiqizi abashintshashintshayo baklama i-algorithm ye-high friction, enciphisa kakhulu ukwenzeka kokuguquguquka kwe-valve.
