Iyini ikhava yevalvu yemoto
Isembozo sevalvu yemoto siyingxenye ewumshini, ngokuvamile eyenziwa ngezinto zensimbi, njenge-aluminium alloy nensimbi ecijile. Itholakala ngaphezu kwesistimu ye-valve phezulu enjini futhi isetshenziselwa ukumboza izingxenye ze-valve kanye ne-valve drive ukuze kuqinisekiswe ukusebenza okuvamile kwesistimu ye-valve. Indima eyinhloko yesembozo se-valve ihlanganisa ukugcina uhlelo lwe-valve luhlanzekile nokuvimbela ukungcola okunjengothuli, ukungcola, imfucumfucu ekungeneni ohlelweni lwe-valve, ngaleyo ndlela ivikela izingxenye ze-valve drive kanye nama-valve bearings. Ngaphezu kwalokho, isembozo se-valve siqinisekisa ukuthi uwoyela awuvuzi noma awungeni ku-valve, ukugwema ukulimala kwengxenye kanye nokumosha uwoyela.
Isakhiwo sesembozo se-valve sihlanganisa umzimba we-valve, isembozo se-valve, i-valve core, ukupakisha, ibhawodi, inathi, i-gasket, isibambo, i-aber kanye nedivayisi yokushayela. Umzimba we-valve uyisakhiwo esiyinhloko sokusekela, futhi isembozo se-valve sitholakala ngaphezu komzimba we-valve ukuze sivale futhi sibambe ukupakisha noma i-spool. I-spool iyingxenye yokulawula elawula isiqondiso sokugeleza, ingcindezi nokugeleza koketshezi. Ukupakisha kutholakala phakathi kwe-spool nebhonethi ukuze kuvalwe futhi kuncishiswe ukuvuza. Ama-bolts namantongomane asetshenziselwa ukuxhuma umzimba we-valve kubhonethi ukuze ubambe ndawonye. I-gasket ihlala phakathi kwebhawodi namantongomane futhi ivikela umzimba nekepisi ekugqokeni. Isibambo sisetshenziselwa ukusebenzisa i-valve, i-bearing isekela i-spool futhi inciphisa ukungqubuzana, futhi idivayisi yokushayela isetshenziselwa ukushayela ukunyakaza kwe-spool ukuze kuzuzwe ukulawula kwe-valve.
Ukugcinwa kwekhava yevalvu nokushintshwa kwayo kubaluleke kakhulu. Ukuhlola nokugcinwa njalo njalo kungavimbela izinkinga ezibangelwa amakepisi amavalvu axegayo noma ukuvaleka kahle. Ukufakwa okungalungile kungabangela ukwehluleka kwe-valve, okungathinta ukusebenza kwenjini nempilo. Lapho ushintsha ibhonethi, into efanayo nosayizi njengengxenye yokuqala kufanele kusetshenziswe ukuze kuqinisekiswe ukusebenza kahle kwenjini.
Indima eyinhloko yekhava ye-valve yemoto ihlanganisa izici ezilandelayo:
Ukuvalwa nokuvikela : isembozo se-valve sisetshenziselwa ukumboza uhlelo lwe-valve ukuvimbela uthuli, ukungcola, imfucumfucu nokunye ukungcola ukuthi kungangeni ku-valve, ngaleyo ndlela kuvikelwe izingxenye zokushayela ama-valve namabheringi, nokuqinisekisa indawo yokusebenza enhle yezingxenye zangaphakathi zenjini.
Ukugcotshwa nokuvimbela uthuli : Isembozo sevalvu ngokuvamile sakha indawo evalekile enazo zonke izingxenye zenjini ukuze kuqinisekiswe ukugcotshwa nokuvikelwa kwezingxenye zangaphakathi zenjini. Ukuvalwa kwayo kubaluleke kakhulu ekusebenzeni okujwayelekile kwenjini, ukuthambisa, ukuvikela nokuvikela uthuli.
Lungisa i-crankcase ventilation : Kwezinye izimo, ikhava yeValve iphinde ibe ne-Positive Crankcase Ventilation Valve (PCV), indima yayo ukulawula inani lentuthu kawoyela ekhiqizwa uhlelo lokungenisa umoya we-crankcase ohlelweni lokudonsa, nokuvala umoya lapho injini ishisa ukuze uvimbele ukwehluleka okufana nokuqhuma kwe-crankcase.
Izinketho ze-Material : Izembozo ze-valve zivame ukwakhiwa ngezinto zensimbi, izinto ezivamile zihlanganisa i-aluminium alloy ne-cast iron. Izembozo zamavalvu e-aluminium alloy azisindi futhi zine-conductivity yokushisa enhle, kuyilapho izimbozo zamavalvu ensimbi zinamandla aphakeme nokuqina.
Izincomo zokunakekela nokushintshwa kwezinye izindawo : Amakhava amavalvu adinga ukuhlolwa nokunakekelwa njalo, ikakhulukazi ukuhlola ukuqina kwawo nokufakwa kwawo. Uma i-valve cap ixega noma ivalwe kahle, ingase iholele ekuhlulekeni kwe-valve, okubuye kube nomthelela ekusebenzeni nempilo yenjini. Lapho ushintsha ibhonethi, into efanayo nosayizi njengengxenye yokuqala kufanele kusetshenziswe ukuze kuqinisekiswe ukusebenza kahle kwenjini.
