Ukuhlolwa phambi kofakelo
I-valve yokulawula kufuneka ihlolwe ngaphambi kokufakwa kwayo ukuze sifumane ukuba kukho nayiphi na impazamo kwi-valve yokulawula kwaye inokulungiswa.Amanyathelo okwenza uhlolo lwevalvu phambi kofakelo lwayo.
• Isalathiso sokuhamba kufuneka simiselwe ukuqinisekisa ukufakwa okufanelekileyo, ezinye iivalvu azikho macala omabini.Ngoko xa kufakwe iivalve zokujonga ujingi ngoko ke indlela yokuhamba kufuneka ijongwe
• Jonga ivalve ngokujonga kwaye ujonge nayiphi na into yangaphandle kwivalve kuba inokuyonakalisa ivalve
• Indawo ye-activator kufuneka imiselwe
Ekuhlolweni kwenkonzo
Iivalve zokulawula zihlolwe kwinkonzo ukufumanisa ukuba kukho nayiphi na ingxaki kwi-valve ngexesha lokusebenza kwayo kunye nokujonga ukuba amacandelo asebenza ngokufanelekileyo phantsi kweemeko zokusebenza eziqhelekileyo.Ngethuba lokuhlolwa kwe-valve ngexesha lenkonzo, kuya kufuneka senze izilungiso ezithile ezifana nokulungelelanisa ukupakisha ukuze i-valve igcinwe kwiimeko ezifanelekileyo zokusebenza.Kufuneka sijonge ibhokisi yokuhlohla kunye neeflange ukuze sazi ukuba kukho ukuvuza okanye hayi.Ke ukuba kukho iziphene kwivalvu kufuneka sithathe inyathelo lokuzibuyisela
Indlela yokukhangela ivalve yokulawula ngelixa uyifumana kumenzi?
Ukuhlolwa okubonakalayo
• Ulawulo lokuthelekisa umphezulu
• Jonga ivili lesandla
• Isihlalo esincamathelayo kunye nolawulo lwesitulo kufuneka zijongwe
• Ukugqitywa kweeflange kufuneka kujongwe
• Jonga amazibuko
• Qwalasela imilinganiselo yomzimba wevalve
• Jonga imilinganiselo yesiphelo
• Ukugqitywa kobuso beflange kunye namalungu eringi kufuneka kujongwe
• Ubuso ngobuso ubukhulu
• Idayamitha engaphandle yeflange, idayamitha yesangqa sebholiti, umngxuma webholi ububanzi, ubukhulu beflange
• Ubukhulu bevalvu yomzimba
• Isiqu sesiqu kunye neziphelo ezinemisonto kufuneka zijongwe
Umhloli wendawo kufuneka ahlole amaxwebhu okuhlola kunye nawo nawuphi na umonakalo owenziwe ngomatshini onokuthi wenzeke ngexesha lokuthunyelwa kwenqanawa.Kufuneka sijonge ukuba i-valve ihanjiswe ngokufanelekileyo okanye cha.
Ezi zinto zilandelayo kufuneka zihlolwe ukuqinisekisa ukuba ivalve yokulawula ihanjiswe ngokufanelekileyo
• Zonke iivalvu kufuneka zikhutshwe ngokupheleleyo kulwelo oluvavanyiweyo kwaye kufuneka zomiswe emva kovavanyo lokuqhutywa kwamanzi
• Isiphelo seflange kunye neeflange zeweld yeevalvu kufuneka zifakelwe izigqubuthelo, kwaye idiameter yokugquma kufuneka ilingane nedayamitha yangaphandle yeflange kwaye kufuneka ijiye nayo.
• Inxalenye yobuso ephakanyisiweyo yeflange kunye nomjelo odibeneyo weringi kufuneka wogqunywe ngegrisi enzima.Idiskhi ekhusela ukufuma enzima kufuneka ifakwe phakathi kobuso obuqatyiweyo beflange kunye nesigqubuthelo.Ububanzi bediski kufuneka bulingane nobubanzi bangaphakathi bemingxuma yebholiti
• Iziphelo zeevalvu eziphothiweyo kunye nesocket weld end kufuneka zikhuselwe ngeminqwazi yeplastiki eqinile
Ukuhlolwa komphezulu
Umgca kunye nokunye ukungafezeki okuqhelekileyo komphezulu kufuneka kuhlolwe ubunzulu.Ukuba ubunzulu bungaphezulu komda owamkelekileyo ocaciswe ukutyeba kodonga ke ezi ziphene zinokuba yingozi.Ngoko ke amalungu kufuneka ahlolwe ukuze kubonwe ukuba awanaziphene ezenzakalisayo kusini na.Iimpawu zoomatshini kwi-abrasion kunye nemingxuma kufuneka zamkeleke kwaye ukuba zidlula umda owamkelekileyo kufuneka zisuswe ngomatshini okanye ngokusila kwisandi sesinyithi.Ukumakishwa kufuneka kube kumzimba okanye kwiipleyiti zokuchonga kwaye iindlela zokumakisha ezamkelekileyo zifakwe, zenziwe ngenkohliso, zifakwe isitampu, zifakwe kwi-electro-etched, i-Vibro-etched, okanye i-laser-etched.Iivalvu ezi-unidirectional kufuneka ziphawulwe ngokuhamba okanye ngokubonisa uxinzelelo.Ipleyiti yokuzazisa kufuneka iphawulwe ngophawu lokuchongwa kwetrim.Iringi yokudibanisa iiflange kufuneka iphawulwe ngenombolo yegroove kwincam yeflange yombhobho.Kufuneka kubekho isalathiso sebhola, iplagi, okanye indawo yedisk yeevalvu zohlobo lokujika kwekota.
