Ngemuva kwekutsi levalve seyisebente kunethiwekhi yemaphayiphi sikhatsi lesitsite, kwehluleka lokuhlukahlukene kutawenteka. Inani letizatfu tekuhluleka kwevalve lihlobene nenani letincenye letakha levalve. Uma kunetincenye letinyenti, kutawuba nekuhluleka lokuvamile; Kufakwa, kusebenta kwesimo sekusebenta, kanye nekunakekelwa kuhlobana. Ngalokuvamile, kwehluleka lokuvamile kwemavalvu langacondziswa ngemandla kungahlukaniswa cishe ngetigaba letine letilandzelako.
1. Leivalvuumtimba ulimele futsi udzabukile
Tizatfu tekulimala kwemtimba wevalvi kanye nekudzabuka: Kuncipha kwekumelana nekugcola kwe .ivalvuimphahla; kuhlala kwesisekelo semaphayiphi; tingucuko letinkhulu tekucindzeteleka kwenethiwekhi yemaphayiphi noma umehluko wekushisa; isando semanti; kusebenta lokungakafaneli kwemavalvu ekuvala, njll.
Imbangela yangaphandle kumele isuswe ngesikhatsi bese luhlobo lolufanako lwe valve noma ivalve kumele ishintjwe.
2. Kwehluleka kwekudlulisela
Kwehluleka kwekudlulisela kuvame kubonakala njengeticu letibhajwe, kusebenta lokucinile, noma emavalvu langasebenti.
Tizatfu nguleti: i .ivalvuirusile ngemuva kwekuvalwa sikhatsi lesidze; intambo yesicu sevalve noma nati yesicu ilimele ngekufakwa lokungakafaneli kanye nekusebenta; lisango linamatsele emtimbeni wevalve ngetintfo tangephandle; Iivalvusikulufu sesicu kanye nentambo ye-valve stem nut ayihambisani kahle, ikhululekile, futsi ibanjwe; lokupakisha kucindzetelwa kakhulu futsi sicu sevalve sikhiyiwe; sicu se valve siphushelwa sife noma sinamatsele lilunga lelivalako.
Ngesikhatsi sekunakekelwa, ingxenye yekudlulisela kufanele igcotjwe. Ngekusitwa yi wrench, kanye nekushaya kancane, lesimo sekujamela kanye nekujaca singasuswa; yimisa emanti kute agcinwe noma ufake ivalve esikhundleni sayo.
3. Kuvulwa nekuvalwa kwevalve lokubi
Kuvulwa nekuvalwa lokubi kweivalvukubonakala ngekutsi le valve ayikhoni kuvulwa nobe kuvalwe, futsi i .ivalvuayikhoni kusebenta ngendlela levamile.
Tizatfu nguleti: i .ivalvusicu sigugile; leligede linamatsele noma ligcotjwe uma leligede livaliwe sikhatsi lesidze; lisango liyawa; tintfo tangephandle tinamatsele endzaweni yekuvala noma emgodleni wekuvala; incenye yekudlulisela igcokile futsi ivinjiwe.
Uma uhlangabetana naletimo letingenhla, ungalungisa futsi ugcobise tincenye tekudlulisela; vula bese uvala ivalve ngekuphindzaphindza bese ushayisa tintfo tangephandle ngemanti; noma ufake le valve esikhundleni sayo.
4. Leivalvukuyavuza
Kuvuza kwevalve kubonakala ngekutsi: kuvuza kwemgogodla wesicu sevalve; kuvuza kwendlala; kuvuza kwephedi yerabha ye-flange.
Tizatfu letivamile nguleti: sicu se valve (ishaft ye valve) seyigcotjiwe, seyigcobile futsi seyihlutshiwe, imigodzi kanye nekuchitsa kuvela endzaweni yekuvala; lesivalo siyaguga futsi siyavuta; emabhawudi endlala kanye nemabhawudi ekuxhumana kwe-flange akhululekile.
Ngesikhatsi sekunakekelwa, lendlela yekuvala ingangetwa futsi ifakwe esikhundleni; emanti lamasha angashintjwa kute kulungiswe kabusha indzawo yemabhawudi ekubopha.
Noma ngabe ngukuphi kwehluleka, uma kungalungiswa futsi kugcinwe ngesikhatsi, kungabangela kucitsa imitfombolusito yemanti, futsi lokungetulu kwaloko, kwenta kutsi lonkhe luhlelo lukhubateke. Ngako-ke, tisebenti tekunakekela emavalvu kumele tati tizatfu tekwehluleka kwemavalvu, tikhone kulungisa nekusebentisa emavalvu ngelikhono nangendlela lenembile, tibhekane nekwehluleka lokuhlukahlukene lokuphutfumako ngesikhatsi lesifanele nangendlela lejubako, futsi ticinisekise kusebenta lokujwayelekile kwenethiwekhi yemaphayiphi ekuhlanta emanti.
