Abantu abaningi bafuna ukwazi indlela yokusebenza yevalve yesango evalwe ngokuthambile ukuze bayisebenzise kangcono le valve.Okulandelayo indlela yokusebenza kanye nendlela yokususa amaphutha yevalvu yesango evalwe ngokuthambile:
Okokuqala, isiqondiso sokuvula nokuvala se-valve, opharetha abaningi bavame ukwenza amaphutha lapha, badinga nje ukukhumbula ukuthi isiqondiso sokuvala i-valve sihamba ngewashi.
Okwesibili, uma i-valve yesango yokuvala uphawu ethambile isetshenziswa ohlelweni lwepayipi, idivayisi yomoya ngaphakathi kwevalvu idinga ukusebenza ngezandla, futhi abantu kudingeka basebenzise izindlela zezandla ukuze bayivule futhi bayivale.Uma kuyi-valve enobubanzi obukhulu, inani lezikhathi zokuvula nokuvala zidinga ukugcinwa phakathi kwezikhathi ezingama-200 nezingama-600.
Okwesithathu, ibanga lamandla okuvula nokuvala levalvu yesango elivalwe ngokuthambile lidinga ukugcinwa ngaphakathi kobubanzi obuthile, ikakhulukazi ukuze kongiwe abasebenzi futhi kube lula ukuthi umuntu oyedwa asebenze.Uma ibanga lamandla lidlula leli banga, okungenani abantu ababili kuya kwabathathu bayadingeka ukuze kuqalwe ngempumelelo i-valve..
Okwesine, ubukhulu be-valve kufanele bufane.Lapho ubeka i-valve, kufanele unake i-valve ye-valve yesango ebheke phansi.
I-valve yesango lokuvala elithambileindlela yokususa iphutha:
1. Ukuvuza ekupakishweni kwevalvu yesango evalwe ngokuthambile
(1) Indlala yokupakisha ixega kakhulu, futhi inadi lokucindezela indlala yokupakisha lingaqiniswa ngokulinganayo.
(2) Inani lemibuthano yokupakisha alanele, futhi ukupakisha kufanele kwandiswe.
(3) Ukupakisha kwehluleka ngenxa yokusetshenziswa isikhathi eside noma isitoreji esingafanele.Kufanele kushintshwe ukupakisha okusha.Uma ushintsha, kufanele kuqashelwe ukuthi amalunga phakathi kwendandatho ngayinye kufanele awele futhi anyakaze.
2. Kunegebe phakathi kwepuleti lesango levalvu yesango elivalwe ngokuthambile nendawo yokuvala yesihlalo sevalvu.
(1) Kukhona ukungcola phakathi kwezindawo zokuvala, ezingaqedwa ngokuwashwa.
(2) Uma indawo yokuvala yonakele, kufanele igaywe kabusha, futhi uma kunesidingo, ingaphinde ibekwe futhi icutshungulwe.Indawo yokuvalwa komhlaba kufanele ibe isicaba, futhi ubulukhuni bayo akufanele bube ngaphansi kuka-0.4.
3. Inadi elivuzayo ekuxhumekeni phakathi kwe-valve yomzimba nebhonethi yevalvu yesango elivala-soft ayiqiniswa ngokuqinile noma ayiqiniswe ngokulinganayo, futhi ingashintshwa.
(1) Ukulimala (imifantu eqondile noma izimpawu zemisele, njll.) endaweni yokuvaleka ye-flange kufanele kulungiswe.
(2) I-gasket yonakalisiwe futhi kufanele ishintshwe kufakwe i-gasket entsha.
4. Ukuhanjiswa kwesiqu se-valve yokuvala uphawu okuthambile akuguquki
(1) Uma ukupakisha kuminyene kakhulu, xegisa inadi edlala ngokupakisha kahle.
(2) Ukuma kwegland yokupakisha akulungile, ukuze isiqu se-valve sibambeke, futhi inadi elise-packing gland kufanele ligoqwe ngokulinganayo ukuze libuyisele indlala endaweni yayo evamile.
(3) Izintambo ezisesiqwini kanye ne-stem nut zonakele futhi kufanele zikhishwe ngemva kokuhlakazwa.
Ama-valve esango lokuvala uphawu asetshenziswa kabanzi.I-valve yesango lokuvala elithambile, i-valve yezimboni, ingxenye yokuvula neyokuvala ye-valve yesango lokuvala uphawu yisango, isiqondiso sokunyakaza kwesango sibhekene nesiqondiso soketshezi, i-valve yesango ingavulwa ngokugcwele futhi ivalwe ngokugcwele, futhi ayikwazi ukulungiswa noma ukucindezelwa.Ipuleti lesango linezindawo ezimbili zokuvala.Izindawo ezimbili zokuvala zevalvu yesango eliwunxantathu elisetshenziswa kakhulu zakha umumo we-wedge.I-engeli yomumo we-wedge iyahlukahluka nemingcele yevalvu, ngokuvamile engu-50, no-2°52 lapho izinga lokushisa elimaphakathi lingekho phezulu.
