Ngokuhlaziya isimiso sokwakheka kwevalvu yebhola yepayipi elungisiwe, kwatholakala ukuthi isimiso sokuvala sifana, kusetshenziswa isimiso "somphumela wepiston", futhi isakhiwo sokuvala kuphela esihlukile.
I-valve ekusetshenzisweni kwenkinga ibonakaliswa kakhulu ngamazinga ahlukene, izinhlobo ezahlukene zokuvuza, ngokwesimiso sokwakha uphawu kanye nokufakwa kanye nokuhlaziywa kwekhwalithi yokwakha, izimbangela zokuvuza kwe-valve yilezi zici ezilandelayo.
1. Ukufakwa kwevalvu kanye nekhwalithi yokwakha yisona sizathu esiyinhloko
Ekwakhekeni kokufakwa akunaki ubuso bokuvala ivalvu kanye nokuvikelwa kwendandatho yesihlalo sokuvala, umonakalo wobuso bokuvala; ukufakwa kuqediwe, ukushaywa kwepayipi kanye ne-valve cavity akukaqedi, akuhlanzekile, lapho kusebenza kukhona i-welding slag noma i-gravel enamathele phakathi kwebhola kanye nendandatho yesihlalo sokuvala, okuholela ekwehlulekeni kokuvala. Kulesi simo, esimweni esiphuthumayo, ubuso bokuvala obuphezulu kufanele bufakwe okwesikhashana nge-sealant efanele ukuze kuncishiswe ukuvuza, kodwa ayikwazi ukuxazulula inkinga ngokuphelele, uma kudingeka, ubuso bokuvala ivalvu kanye nendandatho yesihlalo sokuvala kufanele kushintshwe.
2. Ukucutshungulwa kwemishini ye-valve, izinto zokubopha indandatho, kanye nezizathu zekhwalithi yomhlangano
Nakuba isakhiwo se-valve silula, siyadingeka kakhulu ngemikhiqizo yekhwalithi yokucubungula ngomshini, ikhwalithi yaso yokucubungula ithinta ngqo ukusebenza kokuvala. Indandatho yesihlalo sokuvala kanye nesihlalo sendandatho yokuhlangana kanye nendawo ngayinye yobuso bendandatho kufanele ibalwe ngokunembile, ubulukhuni bomphezulu kufanele bufaneleke. Ngaphezu kwalokho, ukukhethwa kwezinto zokuvala ezithambile nakho kubaluleke kakhulu, hhayi nje ukucabangela ukugqwala nokumelana nokuguguleka kodwa futhi nokucabangela ukuqina kwayo nokuqina kwayo. Uma ithambile kakhulu, izothinta ikhono lokuzihlanza; uma ilukhuni kakhulu, kuzoba lula ukuyiphuka.
3. Ukukhetha okunengqondo ngokuya ngesicelo kanye nezimo zokusebenza
Ukusebenza okuhlukile kokuvala kanye nezakhiwo zokuvala zevalvu kusetshenziswa izikhathi ezahlukene, izikhathi ezihlukene kuphela ukukhetha ivalvu ehlukile, ukuthola umphumela wokusebenza ofanele. Endabeni yepayipi legesi laseNtshonalanga-mpumalanga, isibonelo, amavalvu ebhola lepayipi aqinile anokuvala okuqondiswayo okubili kufanele akhethwe ngangokunokwenzeka (ngaphandle kwamavalvu ebhola elijikelezayo anokuvala okuphoqelelwe, okubiza kakhulu). Ngale ndlela, uma uphawu oluphezulu lonakele, uphawu olungezansi lusasebenza. Ivalvu yebhola lethrekhi elivalwe ngenkani kufanele ikhethwe uma kudingeka ukuthembeka okuphelele.
4. Kuma-valve anezilungiselelo ezahlukene zokuvala, kufanele kusetshenziswe izindlela ezahlukene zokusebenza, ukugcinwa, kanye nokunakekelwa
Kuma-valve angenawo ama-clutter, i-valve ingagcwaliswa ngamafutha ngaphambi nangemva kokusebenza ngakunye noma njalo ezinyangeni eziyi-6 ngamanani amancane ezimbotsheni zokujova ze-stem kanye ne-sealant, futhi kuphela ezimweni lapho ukuvuza kwenzeke khona noma kungenakuvalwa ngokuphelele lapho inani elifanele le-sealant lifakwa khona. Ngenxa ye-viscosity ephezulu ye-sealant, uma i-valve ingagcwaliswanga nge-sealant ngokuvamile, izothinta umphumela wokuzihlanza wobuso obuyindilinga, ovame ukungasizi ngalutho, okuletha ukungcola okuncane kanye nokunye ukungcola phakathi kwe-seal okubangela ukuvuza. Kuma-valve anophawu olunezinhlangothi ezimbili, uma izimo zokuphepha kwendawo zivuma, ingcindezi emgodini we-valve kufanele ikhululwe iye ku-zero, ukuqinisekisa ukuvalwa.
