Yiziphi izinkinga ezivamile nezisombululo zamavalvu ovemvane ngesikhathi sokusetshenziswa?
I-valve ye-Butterfly ngenxa yobukhulu bayo obuncane kanye nesakhiwo esilula, isibe yinye yama-valve asetshenziswa kakhulu embonini, ayanda futhi asetshenziswa emandleni kagesi wamanzi, ukuchelela, ukwakhiwa kwamanzi nokukhipha amanzi, ubunjiniyela bakamasipala nezinye izinhlelo zamapayipi, ezisetshenziselwa ukunqamula noma ukulamula ukugeleza kokugeleza kwemidiya ejikelezayo ukuze kusetshenziswe. Khona-ke i-valve ye-butterfly ekusetshenzisweni kwezinkinga ezidinga ukunakwa nezixazululo kulokho, namuhla sizobe siqondile ukuqonda.
Ukufakwa kwe-Butterfly valve kudinga ukunakwa:
1.Ngaphambi kokufaka, sicela uqinisekise ukusebenza komkhiqizo kanye nomcibisholo wokugeleza kwemidiya uhambisana nokuhamba kwezimo zokusebenza, futhi kuyoba i-valve cavity ekhuhlwe, ungavumeli ukungcola kwendandatho yokuvala uphawu kanye nepuleti yevemvane enamathiselwe ezintweni zangaphandle, engahlanjululwanga ngaphambili futhi ayivunyelwe ukuvala ipuleti yevemvane, ukuze ungalimazi indandatho yokuvala.
2.Disc ukufakwa ipuleti asekelayo flange Kunconywa ukusebenzisa flange uvemvane valve ekhethekile.
3.Kufakwe phakathi kwepayipi noma indawo yeziphetho ezimbili zepayipi, indawo engcono kakhulu yokufakwa okuqondile, ayikwazi ukufakwa ibheke phansi.
4. Ukusetshenziswa kwesidingo sokulawula ukugeleza, kukhona ama-manual, kagesi, ama-actuator we-pneumatic wokulawula.
5. Vula futhi uvale ngokuvamile uvemvane valve, cishe izinyanga ezimbili, kudingeka uvule isembozo gear ibhokisi worm, hlola ukuthi ibhotela kuyinto evamile, kufanele ugcine inani elifanele ibhotela.
6.Hlola ukuthi izingxenye zokuhlanganisa zicindezelwe yini, okungukuthi, ukuqinisekisa ukuvala ukupakisha, kodwa futhi ukuqinisekisa ukuthi ukujikeleza kwe-valve stem kuyaguquguquka.
7. Imikhiqizo yevalve ye-metal seal butterfly ayifanele ukufakwa ekupheleni kwepayipi, njengokuthi kufanele ifakwe ekupheleni kwepayipi, udinga ukuthatha i-flange yokukhipha efakiwe, ukuvimbela ukunqwabelana kwendandatho yokuvala ingcindezi, phezu kwendawo.
I-8.Ukufakwa kwe-valve stem kanye nokusetshenziswa kwempendulo ukuhlola njalo ukusebenza kwe-valve, kutholwe amaphutha ngesikhathi esifanele.
Izimbangela ezingenzeka zokwehluleka: ukuvala ukuvuza kwendawo
Ipuleti le-1.Valve, imfucumfucu yefolda evala uphawu
Ipuleti le-2.Valve, indawo yokuvala indawo yokuvala ihambisana nokungalungile
3.I-Outlet side yokucushwa ifaka amabhawodi e-flange amandla angalingani noma amabhawodi axegayo
4.Isiqondiso sokuhlolwa kokucindezela asihambisani nezidingo zesiqondiso sokugeleza okuphakathi.
Izindlela zokuqeda
1.Susa ukungcola, hlanza i-valve yangaphakathi
2.Lungisa igiya lesikelemu noma izikulufu zikagesi, i-pneumatic actuator ukuze ufinyelele indawo efanele yokuvalwa kwevalvu.
3.Ukuhlola indiza ye-flange efakiwe kanye ne-bolt compression fastening, kufanele kucindezelwe ngokufanayo
4.Ngokwendlela yokuvala umcibisholo ukuze uthole ingcindezi
Izimbangela zokuvuza kwe-valve ezimbili ziphela
1.Zombili izinhlangothi zokuhluleka kwe-gasket yokuvala
I-2.Ukuqina kwe-Pipe flange akufani noma akucindezelwe
3.Indandatho yokuvala noma indandatho yokuvala ekuhlulekeni kwe-gasket
Indlela yokuqeda
1. Faka esikhundleni i-gasket yokuvala
2.Amabhawudi e-pressure flange (amandla afanayo)
3.khipha indandatho ye-valve yokucindezela, buyisela indandatho yokuvala kanye nokuhluleka kwe-gasket.
I-valve yovemvane ingahlukaniswa ngomugqa omaphakathi uvemvane iveve kanye ne-eccentric butterfly valve ngokuya ngesakhiwo. Ngokusho ifomu lokubeka uphawu zingahlukaniswa zibe soft uhlobo uphawu futhi uhlobo uphawu oluqinile. Uhlobo oluthambile lokuvala ngokuvamile lusebenzisa isihlalo se-valve yenjoloba noma ukuvala indandatho yerabha, uhlobo oluqinile lokuvala ngokuvamile lusebenzisa ukuvala indandatho yensimbi. Ngokusho kohlobo lokuxhuma, ingahlukaniswa ibe uxhumano lwe-flange nokuxhumeka kwe-wafer; ngokuya ngemodi yokudlulisa, ingahlukaniswa ibe imanuwali, kagesi, i-pneumatic kanye ne-hydraulic. Singakhetha ama-actuator ahlukene ngokuya ngezimo zokusebenza.
