Xa ufaka i-valve yesango, ukwenzela ukukhusela izinto zangaphandle ezifana nentsimbi kunye nesanti ekungeneni kwi-valve yesango kunye nokonakalisa indawo yokutywina;kuyimfuneko ukuseta isihluzo kunye nevalve yokugungxula.Ukuze ugcine umoya ocinezelweyo ucocekile, isahluli samanzi e-oyile okanye isihluzo somoya kufuneka sifakwe phambi kwevalve yesango.Ukuqwalasela ukuba imeko yokusebenza ye-valve yesango inokujongwa ngexesha lokusebenza, kuyimfuneko ukuseta izixhobo kunye nokujonga i-valve.
Umenzi wevalve yesango uthe ukuze kugcinwe ubushushu bokusebenza, izibonelelo zokufakelwa kwe-thermal zifakwe ngaphandle kwevalve yesango;ukufakwa emva kwevalve, ivalve yokhuseleko okanye ivalve yokukhangela kufuneka ibekwe;ngokuqwalasela ukusebenza okuqhubekayo kwevalve yesango, ekulungeleyo kwaye iyingozi, inkqubo ehambelanayo okanye inkqubo yokudlula imiselwe.
1. Qwalasela izibonelelo zokhuselo lwevalvu yesango:
I-valve enye okanye ezimbini zokuvala zifakwe ngaphambi nangemva kwe-valve yokutshekisha ukwenzela ukuthintela ukuwohloka komgangatho wemveliso, iingozi kunye nezinye iziphumo ezibi ezibangelwa ukuvuza okanye ukubuya kwe-medium backflow emva kokuba i-valve yokukhangela ingaphumeleli.Ivalve yokukhangela inokususwa ngokulula kwaye inikwe inkonzo ukuba iivalve ezimbini zokuvala zibonelelwe.
2. Ukuphunyezwa kokhuseleko lwevalvu yokhuseleko
Ivalve yokuvala ngokuqhelekileyo ayimiselwanga ngaphambi nangemva kwendlela yokufaka, kwaye ingasetyenziswa kuphela kwiimeko zomntu ngamnye.Khumbuza wonke umntu ukuba ukuba amandla aphakathi aqulethe amasuntswana aqinileyo, aya kuchaphazela ivalve yokhuseleko ekubeni itshixiwe emva kokumka.Ngoko ke, ivalve yesango etywiniweyo kufuneka ifakwe ngaphambi nangemva kwevalve yokhuseleko.Iivalvu zesango kunye nokhuseleko kufuneka zivuleke ngokupheleleyo kwaye ivalve yokujonga i-DN20 kwi-atmosfera kufuneka ifakwe ngokuthe ngqo.Abavelisi bevalvu yesango
Umvelisi wevalve yesango wathi kwiqondo lokushisa eliqhelekileyo, xa i-medium efana ne-wax ekhupha ngokukhawuleza iqinile, okanye xa i-gasification ye-gasification yolwelo olukhanyayo kunye nezinye i-medium ingaphantsi kwe-0 ngenxa yoxinzelelo, ukulandelwa komphunga kuyadingeka.Ukuba i-valve yokukhusela isetyenziswe kwindawo ephazamisayo, ngoko ke ngokokumelana nokubola kwevalve yesango, kuyimfuneko yokongeza ifilimu enganyangekiyo yokuqhuma ifilimu ekungeneni kwevalve yesango.Ngokuqhelekileyo, iivalve zokhuseleko lwegesi zixhotyiswe ngevalve ye-bypass ye-venting manual ngokuxhomekeke kubukhulu bazo.
3. Izixhobo zokukhusela zevalve yokunciphisa uxinzelelo:
Ngokuqhelekileyo kukho iintlobo ezintathu zeendawo zokufakela iivalvu zokunciphisa uxinzelelo.Iigeyiji zoxinzelelo zifakwe ngaphambi nangemva kwevalve yokunciphisa uxinzelelo, ekulungele ukujonga uxinzelelo ngaphambi nangemva kwevalve.Fakela ivalve yokhuseleko evalwe ngokupheleleyo emva kwevalve yesango ukuthintela ukusilela kwevalve yesango.Xa uxinzelelo emva kwevalve ludlula uxinzelelo oluqhelekileyo, inkqubo emva kwevalve iyatsiba.Abavelisi bevalvu yesango
Umbhobho wokucoca ufakwe phambi kwevalve yokuvala phambi kwevalve yesango, kwaye isetyenziselwa ikakhulu ukugungxula umjelo wokukhupha amanzi.Ezinye zazo zisebenzisa imigibe yomphunga.Umbhobho we-bypass usetyenziselwa ukuvala i-valve yokuvala, uvule i-valve ye-bypass, kwaye ulungise ngesandla ukuhamba ngaphambi nangemva kokungaphumeleli kwe-valve yokunciphisa uxinzelelo.Iyakwazi ukujikeleziswa kwaye emva koko ivalve yokukhulula ilungiswe okanye itshintshwe.
4. Izibonelelo zokhuseleko kwimigibe yomphunga:
Umvelisi wevalvu yesango uthe kukho iindidi ezimbini zemigibe enemibhobho edlulayo nangaphandle kwayo, kuquka imigibe eneemfuno ezikhethekileyo ezifana nokubuyiswa kwe-condensate, ukungabuyiswa kwe-condensate, kunye nemirhumo yokuhambisa amanzi.Inokufakwa ngokuhambelanayo.Iinjineli zethu zikukhumbuza ukuba xa ujonga imigibe, musa ukukhupha i-condensate kumgca wokudlula, oya kuvumela umphunga ukuba ubaleke kwaye ubuyele kwinkqubo yamanzi.Kwiimeko eziqhelekileyo, akukho mfuneko yokufakela umbhobho we-bypass, kwaye ifanelekile kuphela izixhobo zokufudumeza kunye neemfuno eziqinileyo zokushisa ukushisa kwimveliso eqhubekayo.
