I-valve yebhola yokulawula yohlobo lwe-V yomoya

I-valve yebhola yokulawula yohlobo lwe-V ephefumulayo isetshenziswa kakhulu ekulawuleni ukulawulwa kokugeleza ezinhlelweni zamapayipi, ifanele izimo zokusebenza ezidinga ukunemba okuphezulu kokulawulwa kanye nokuqina kokulawula. I-valve isebenzisa isakhiwo sebhola lokuvula elinomfanekiso we-V, kanye nesici salo sokugeleza esisondela ku-curve yephesenti elilinganayo, okuvumela izinguquko zokugeleza ezibushelelezi nezilawulekayo ngaphakathi kobubanzi bokuvula. Ivame ukusetshenziswa ezinhlelweni zokulawula izinqubo.

Ivalvu isebenza nge-actuator elawulwa ngogesi eqhutshwa umoya. Ingalungisa ngokunembile ukuvulwa kwevalvu ngokwesignali yokulawula ukuze kufezwe ukulawulwa okuqhubekayo. Isiteshi sokugeleza esinobunjwa obungu-V sisenamandla amahle okulawula uma sivuliwe kancane, okusiza ekuthuthukiseni ukuzwela kokulawulwa futhi kuncishiswe ukugeleza kwamanzi, okuwusizo ekuzinzeni kokusebenza kwesistimu.

I-actuator ingakhethwa ngokuya ngezidingo zenqubo nokuphepha, okuhlanganisa ukuvula amaphutha, ukuvala amaphutha, noma indawo yokubamba amaphutha. I-valve isekela ukusebenza kwendawo kanye nokulawula okude, futhi ingalungiswa ngezikhombisi-ndlela, ukushintsha komkhawulo, kanye namamojula okuxhumana njengoba kudingeka, okwenza kube lula ukuxhumana nezinhlelo ze-DCS noma ze-PLC zokulawula okuphakathi kanye nokuqapha isimo sokusebenza.

Isikhathi sokusebenza kwevalvu singakhethwa ngokuya ngezimo zangempela zokusebenza, sihlangabezane nezidingo zokulawula ezijwayelekile kanye nezihibe zokulawula ezinesidingo sesivinini sokuphendula. Uma isetshenziswa njengevalvu yokulawula ukugeleza, ivalvu yebhola yokulawula yohlobo lwe-V ephefumulayo ingagcina ukuzinza kokusebenza okuhle kanye nokuzivumelanisa nezimo ngenkathi iqinisekisa ukunemba kokulawula.
