I-valve eqondile yokuqondisaisetshenziselwa ukulawula indlela ye-waft yomoya, amanzi, noma uketshezi oluhlukile kudivayisi, evame kwimibuthano ye-pneumatic noma ye-hydraulic. Umsebenzi wayo wokuqala ukuqondisa uketshezi luhambe ngokugeleza phakathi kwengxenye eyodwa -
Izici ezibalulekile ze-5/2 Direction Phatha i-Valve:
Inkambo yokugeleza
I-valve ingadlulisela indlela ye-waft, iqondise uketshezi oluvela ekuhlinzekeni kwengcindezi (p) kwelinye lamachweba okusebenza (a noma b), futhi nokukhipha uketshezi oluvela kwenye imbobo (i-Exp noma i-ExID). Lokhu kulawula ukunyakaza kwe-Double - i-actuator esebenzayo (kufaka phakathi ipiston noma isilinda).
Indima 1: I-Stress Port (P) ixhumeka ethekwini a, futhi iPort B ikhathele nge-EXIK2.
Indima 2: I-Stress Port (P) ixhumeka ePort B, kanye nePort A kuphelelwe amandla nge-EXIK1.
Ukulawulwa kokuhamba kwe-Actuator:
Ezakhiweni ze-pneumatic, ilawula ukwenziwa okukhulu nokubuyisa ukujula kwe-cylinder ephindwe kabili -
Ngenkathi i-valve isemsebenzini owodwa, ivumela umoya ukujikeleza uhlangothi olulodwa lwesilinda, okubangela ukuba ludlule.
Ngenkathi i-valve isuka komsebenzi ophambene, iqondisa umoya esicini esiphambene sesilinda, ibangele ukubuyisa.
Ezishintshayo nokuphepha:
Ama-5/2 ama-valves angaba ngekhompyutha ngama-solenoids, lapho izexwayiso zikagesi zibangela i-valve ukuba iguqukele phakathi kwezikhundla zayo ezimbili. Lokhu kwenza kube kulungele ukulawula imishini yokulawula kanye negajethi edinga ukulawula okuhlukile ngokunyakaza kwabo noma ukunyakaza.
Ivumela ukuqinisekisa ukusebenza okuphephile futhi okusebenzayo ezinhlelweni ezenzakalelayo ngokuveza indlela ethembekile yokushintsha uketshezi oluhamba ngokugeleza.
Igajethi Ukuhlukaniswa:
I-valve ingahlukanisa izinto zomshini ngokuxhuma noma ukunqamula indlela ye-waft. Isibonelo, lapho i-valve isendimeni eguqukile, ingahlukanisa isici esisodwa soMfundisi, ilondoloze esifundeni.
Amaphakheji:
I-Double - yenza ama-cylinders: hhayi engajwayelekile ezinhlelweni ezenzakalelayo, amarobhothi, ukucindezela, kanye nanoma yiluphi uhlelo lokusebenza oludinga ukunwetshwa ngakunye nokubuyiselwa.
Izakhiwo ezisetshenziswayo ezibonakalayo: Ngokulawula ukusunduza / ukudonsa ukunyakaza.
Okokusebenza okwenziwe ngekhompyutha: ukulawula ukusebenza okuhle kwezinto eziningi zemishini, kaningi ngasohlangothini lwezinzwa nabalawuli.
Isifinyezo:
I-valve yesihlanu / 2 yokuqondisa indlela eqondile ivame ukusetshenziselwa ukuphatha ukuqondiswa koketshezi ku-actuators, ngokuvamile ezinhlelweni lapho kusetshenziswa ama-cylinder. Iguqukela phakathi kwezikhundla ezimbili ukuze ikhombe noma ngabe umbhali udlulela noma abuyiselwe emuva, ukugembula indima ebalulekile ngaphakathi kwezakhiwo ezisetshenziswayo ze-fluid -.
