Ngokuhlaziya kanye nocwaningo ngomgomo wesakhiwo sepayipi elingaguqukii-valve yebhola, kutholakala ukuthi isimiso sokuvala siyafana, futhi isimiso se-' piston effect ' siyasetshenziswa, kodwa isakhiwo sokuvala sihlukile.
Izinkinga ezikhona ekusetshenzisweni kwama-valve zibonakaliswa ngokuyinhloko ngamazinga ahlukene kanye nezinhlobo ezahlukene zokuvuza.Ngokomgomo wesakhiwo sokubeka uphawu kanye nokuhlaziywa kwekhwalithi yokufaka nokwakhiwa, izimbangela zokuvuza kwe-valve zimi kanje.
(1) Ikhwalithi yokwakha i-valve iyisizathu esiyinhloko.
Ekufakeni nasekwakhiweni, ukuvikelwa kwendawo yokuvala i-valve kanye nendandatho yokuvala isihlalo akunakwa, kanti indawo yokuvala yonakala.Ngemuva kokuthi ukufakwa sekuqediwe, ipayipi kanye negumbi le-valve akuhlanzwa kahle futhi ngokuhlanzekile.Ekusebenzeni, i-slag noma igravel yokushisela ibambeke phakathi kwendilinga kanye nendandatho yesihlalo sokuvala, okuholela ekuhlulekeni kokuvala.Kulokhu, inani elifanele le-sealant kufanele lifakwe okwesikhashana endaweni yokuvala ekhuphuka nomfula esimweni esiphuthumayo ukuze kudambiswe ukuvuza, kodwa inkinga ayikwazi ukuxazululeka ngokuphelele.Uma kunesidingo, indawo yokuvala i-valve kanye neringi yesihlalo sokuvala kufanele kushintshwe.
(2) Imishini yevalvu, indandatho yokuvala uphawu kanye nezizathu zekhwalithi yomhlangano
Nakuba isakhiwo se-valve silula, siwumkhiqizo odinga izinga eliphezulu lemishini, futhi izinga layo lomshini lithinta ngokuqondile ukusebenza kokuvala.Imvume yokuhlanganisa kanye nendawo ngayinye ye-torus yendandatho yokuvala kanye nesihlalo esiyindandatho kufanele kubalwe ngokunembile, futhi ubulukhuni obungaphezulu kufanele bufaneleke.Ngaphezu kwalokho, ukukhethwa kwezinto ezithambile zokuvala uphawu kubaluleke kakhulu, hhayi nje ukucabangela ukumelana nokugqwala nokumelana nokugqoka, kodwa futhi ukucabangela ukuqina nokuqina kwayo.Uma ukuthambile kakhulu kuzothinta ikhono lokuzihlanza, kunzima kakhulu ukuphuka.
(3) Ukukhetha okunengqondo ngokwesicelo kanye nezimo zokusebenza
Amavalvungokusebenza okuhlukene kokuvala kanye nesakhiwo sokubeka uphawu kusetshenziswa ngezikhathi ezahlukene.Kuphela ngokukhetha ama-valve ahlukene ngezikhathi ezihlukene kungatholakala umphumela omuhle wohlelo lokusebenza.Uma sithatha ipayipi legesi eliseNtshonalanga-mpumalanga njengesibonelo, i-valve yebhola yepayipi egxilile enomsebenzi wokuvala indlela emibili kufanele ikhethwe ngokusemandleni ( ngaphandle kwe-valve yebhola yethrekhi evalwa ngempoqo, ngoba ibiza kakhulu ).Ngakho-ke, uma uphawu lwaphezulu selimele, uphawu olungezansi lusengasebenza.Uma kudingeka ukwethembeka okuphelele, i-valve yebhola yethrekhi enophawu oluphoqelelwe kufanele kukhethwe.
(4)Amavalvu anezakhiwo ezihlukene zokuvala kufanele asetshenziswe, anakekelwe futhi ahlinzekwe ngezindlela ezahlukene
Ngobaama-valvengaphandle kokuvuza, inani elincane lamafutha lingangezwa esiqwini se-valve kanye nembobo yomjovo we-sealant ngaphambi nangemva kokusebenza ngakunye noma njalo ezinyangeni eziyisi-6.Kuphela uma ukuvuza sekwenzekile noma kungenakuvalwa ngokuphelele, inani elifanele le-sealant lingajovwa.Ngenxa yokuthi i-viscosity ye-sealant inkulu kakhulu, uma i-sealant yengezwa ku-valve engavuzi, izophazamisa umphumela wokuzihlanza kwendawo eyindilinga, evame ukuphikisana, kanti amanye amatshe amancane nokunye ukungcola kulethwa. uphawu lokubangela ukuvuza.Ku-valve enomsebenzi wokuvala wezindlela ezimbili, uma izimo zokuphepha zesayithi zivuma, ingcindezi egunjini le-valve kufanele idedelwe ibe yiziro, evumela ukuthi kuqinisekiswe kangcono ukuvala.
