Ngokuhlaziywa kwesimiso sesakhiwo se-valve yebhola yephayiphi engashintshi, kwatholakala ukuthi isimiso sokuvala siyafana, kusetshenziswa isimiso “somphumela we-piston,” futhi isakhiwo sokuvala kuphela esihlukile.
I-valve ekusetshenzisweni kwenkinga ibonakala ngokuyinhloko ngamadigri ahlukene, izinhlobo ezahlukene zokuvuza, ngokusho kwesimiso sokuvala isakhiwo nokufakwa nokuhlaziywa kwekhwalithi yokwakha, izimbangela zokuvuza kwe-valve yizici ezilandelayo.
1. Ukufakwa kwe-valve kanye nekhwalithi yokwakha yisizathu esiyinhloko
Ekwakhiweni kokufakwa akunaki indawo yokuvala i-valve nokuvala ukuvikelwa kwendandatho yesihlalo, ukulimala kwendawo yokubeka uphawu;ukufakwa sekuqediwe, ukuvunguza kwepayipi kanye nembobo ye-valve akuphelele, akuhlanzekile, lapho kusebenza kukhona i-slag yokushisela noma i-gravel enamathele phakathi kwebhola nendandatho yesihlalo yokuvala, okuholela ekuhlulekeni kokuvala.Kulesi simo, esimweni esiphuthumayo, indawo engaphezulu yokuvala umfula kufanele ijovwe okwesikhashana ngenani elifanele le-sealant ukuze kuncishiswe ukuvuza, kodwa ayikwazi ukuxazulula inkinga ngokuphelele, uma kunesidingo, indawo yokuvala i-valve kanye nendandatho yesihlalo sokuvala kufanele kushintshwe.
2. I-valve mechanical processing, indandatho yokuvala uphawu, nezizathu zekhwalithi yomhlangano
Nakuba isakhiwo se-valve silula, siyisidingo esikhulu semikhiqizo yekhwalithi yokucubungula imishini, ikhwalithi yayo yokucubungula ithinta ngokuqondile ukusebenza kokubeka uphawu.Vala indandatho yesihlalo kanye nesembozo sokuhlanganisa isihlalo kanye nendawo ngayinye eyindandatho yokubalwa ngokunembile, ubulukhuni obungaphezulu kufanele bufaneleke.Ngaphezu kwalokho, ukukhethwa kwezinto ezithambile ze-seal nakho kubaluleke kakhulu, hhayi nje ukucabangela ukugqwala nokumelana nokugqoka kodwa futhi ukucabangela ukuqina nokuqina kwayo.Uma ithambile kakhulu, izothinta ikhono lokuzihlanza;uma kunzima kakhulu, kuzoba lula ukuphuka.
3. Ukukhetha okunengqondo ngokwesicelo kanye nezimo zokusebenza
Ukusebenza okuhlukile kokuvala kanye nezakhiwo zokuvala ze-valve kusetshenziswa izikhathi ezihlukene, izikhathi ezihlukene kuphela zokukhetha i-valve ehlukile, ukuthola umphumela ofanele wohlelo.Endabeni yepayipi legesi eliseNtshonalanga-Mpumalanga, isibonelo, amavalvu ebhola ephayiphi angaguquki anokuvalwa kwendawo ekabili kufanele akhethwe ngokusemandleni (ngaphandle kwamavalvu ebhola azungezayo anokuvalwa ngempoqo, abiza kakhulu).Ngale ndlela, uma uphawu olukhuphuka nomfula lonakele, uphawu olungezansi lusengasebenza.I-valve yebhola yethrekhi evalwe ngenkani kufanele ikhethwe uma kudingeka ukwethembeka okuphelele.
4. Kuma-valve anezinhlelo ezihlukene zokuvala, kufanele kusetshenziswe izindlela ezihlukene zokusebenza, ukugcinwa, nokusevisa.
Kumavalvu angenakho ukuvuza, ivalvu ingagcwaliswa ngamafutha ngaphambi nangemva kokusebenza ngakunye noma njalo ezinyangeni eziyisi-6 ngamanani amancane esiqwini kanye namachweba omjovo we-sealant, futhi kuphela ezimeni lapho kuvuza khona noma kungenakuvaleka ngokuphelele. inani elifanele le-sealant ejovwe.Ngenxa ye-viscosity ephezulu ye-sealant, uma i-valve ingagcwaliswa nge-sealant, izophazamisa umphumela wokuzihlanza kwendawo eyindilinga, ngokuvamile ephikisanayo, ilethe i-grit encane nokunye ukungcola phakathi kophawu ukuze kubangele ukuvuza.Kuma-valve ane-seal-way seal, uma izimo zokuphepha zesayithi zivuma, ukucindezela emgodini we-valve kufanele kukhishwe ku-zero, ukuqinisekisa ukuvala.
