Ukuhlolwa kweValve
I. UmgangathoImfuneko
Iimfuno ezifanelekileyo zomgangatho wevalvu zibekiwephambilikwimigangatho.
①Icandelo lekhemikhali kunyeimpahla yoomatshiniyezixhobo eziphambili zevalve zihambelana neemfuno kwimigangatho yemathiriyeli efanelekileyo.
②Ubume nobungakanani bempazamo yevalveiicastingsukuhlangabezana nemigaqo kwimizobo.
③IengasetyenzwangaUmphezulu we-valve uya kuba mcaba, ugudileyo kwaye ungabikhoisanti yokubambelela, isikhumba oxide, umngxuma,ukufakwa kwesanti, iintanda okanye ezinye iziphene.The ukusasaza ngochwethezoumqondiso uya kucaca, kwaye umqondisospruekwayeisikhuphukeliiya kuhlala ilingana nomphezulu wecastings emva kokucoca.
④Zonke iindawo zevalvuuyauqhagamshelwe ngokuqinileyo kwaye ukhululeke ekukhululekeni.
⑤Tyena iziphumo zovavanyo loxinzelelo kunyeukutywinauvavanyo lokusebenza kwivalveukuhambelanato imfunekos yemigangatho yovavanyo efanelekileyo.
⑥Iumsebenzi wevalvu uya kuba phantsi koxinzelelo lwegama kwaye utyunjweuxinzelelo olwahlukileyo, kwaye ivalve yokuqalisa nokumisa iya kukhululeka kuyoukubamba.
⑦Inayo ingokuqinisekileyoamaxesha okusebenza kunye nobomi benkonzo.
⑧It'iboniswe ngconoumthamo wokuhamba(ithetha ukubauxinzeleloilahleko kwivalvu incinci emva kokudlula kuyo).
II.Indlela yoVavanyo kunye nokuHlola
1,UkusaswaUmgangatho
Iiicastingsimilo kunye nobukhulu buya kuhambelana neimfunekoyemizobo yobugcisa kunye nemimiselo evelaumfuni.Iubuncinaneubukhulu bodonga lwamalungu evalvu, impazamo yobude bolwakhiwo,ukususwa kwe-abrasionisibonelelo seipleyiti yesangoayiyi kuthoba kuneemfuno kumgangatho wobugcisa bemveliso kunye nemizobo yemveliso.Umphezulu orhabaxaivalvekwaye iqokobhe elicinezelekileyo lemveliso yevalvu egqityiweyo ayisayi kuba neentanda,ukuvala okubandayo, ukufakwa kwesanti, i pore kunye nezinye iziphene.The isanti yokubambelela, sprue, isikhuphukelikwayeisikhumba oxidekumphezulu wokuphosa uya kucocwa.
2,UxinzeleloUvavanyo
Uvavanyo loxinzelelo lolona lukhuluisisekouvavanyo lwevalvu.EIvalve nganye iya kuqhutyelwa uvavanyo loxinzelelo phambi kokuba ihanjiswe kumzi-mveliso.Tuvavanya uxinzelelo kunye nobude bexesha balandela ummiselo kwiGB/ T13927, kunye nezinto zovavanyo zigubungela uvavanyo lweqokobhe kunye novavanyo lokutywinwa.Ukuba nayiphi nangasemvaisakhiwo sokutywina kwivalve, kuyafuneka ukuqhubauvavanyo emva kwetywina. Dumchamo inkqubo yovavanyo, iamandla angaphandleezinokuthi zichaphazele iziphumo zovavanyo aziyi kufakwa kwivalvu.Uxinzelelo lovavanyo luya kuhlala luhleli ngexesha lenkqubo yokubamba uxinzelelo kunye novavanyo.
Uvavanyo lweqokobhe lwevalvu luhlobo lovavanyo loxinzelelo lweqokobhe levalvu epheleleyo edityaniswe ngumzimba wevalvu kunye nesigqubuthelo.Injongo yayo kukukhangela iukubumbanaphakathi komzimba wevalvu kunye nesigqubuthelo, oko kukuthi, i-anti-uxinzeleloumthamo weqokobhe elipheleleyo kubandakanya uqhagamshelo lomzimba wevalvu kunye nesigqubuthelo.
Iuvavanyo lokutywina kukukhangela ukusebenza kweiindawo ezivaliweyokunye nevalveiperi yokutywina, kwaye inokwahlulwa ibe luvavanyo lokutywinwa koxinzelelo oluphezulu kunye novavanyo lokutywinwa lomoya oluphantsi.
Ingakunika ntoni i-EC?
EzoQoqosho: Ngesiqingatha sexabiso lemizi-mveliso, yonwabele inkonzo yokuhlola ekhawulezileyo kunye neyobuchwephesha ekusebenzeni okuphezulu
Inkonzo ekhawulezayo kakhulu: Ngombulelo wokucwangcisa ngokukhawuleza, ukuqukunjelwa kokuhlolwa kwangaphambili kwe-EC kunokufunyanwa kwisiza emva kokuba ukuhlolwa kugqityiwe, kwaye ingxelo yokuhlola ngokusemthethweni evela kwi-EC ingafunyanwa kwi-1 yosuku lomsebenzi;ukuthunyelwa ngexesha kunokuqinisekiswa.
Ukongamela elubala: Ingxelo yexesha langempela yabahloli;ulawulo olungqongqo lokusebenza kwisiza
Ukungqongqo nokunyaniseka: Amaqela aqeqeshiweyo e-EC kwilizwe jikelele abonelela ngeenkonzo zobungcali kuwe;Iqela elizimeleyo, elivulelekileyo nelingenabuqhophololo limiselwe ukuba lihlole amaqela okuhlola kwindawo ngokungenamkhethe kwaye libe liliso kwisiza.
Inkonzo eyenziwe ngokwezifiso: I-EC inamandla enkonzo ehamba kuyo yonke ikhonkco lokubonelela ngemveliso.Siza kubonelela ngeskimu senkonzo yokuhlola elungiselelwe imfuno yakho ethile, ukuze uzisombulule iingxaki zakho ngokukodwa, unikeze iqonga lokusebenzisana elizimeleyo kwaye uqokelele iingcebiso zakho kunye nengxelo yenkonzo malunga neqela lokuhlola.Ngale ndlela, unokuthatha inxaxheba kulawulo lweqela lokuhlola.Kwangaxeshanye, kutshintshiselwano lwetekhnoloji yonxibelelwano kunye nonxibelelwano, siya kubonelela ngoqeqesho lokuhlola, ikhosi yolawulo lomgangatho kunye nesemina yetekhnoloji kwimfuno yakho kunye nengxelo.
IQela loMgangatho we-EC
Uyilo lwamazwe ngamazwe: i-QC ephezulu igubungela amaphondo asekhaya kunye nezixeko kunye namazwe angama-12 kuMzantsi-mpuma we-Asia
Iinkonzo zengingqi: i-QC yendawo inokubonelela ngeenkonzo zokuhlola iingcali ngokukhawuleza ukugcina iindleko zakho zokuhamba.
Iqela lobuchwephesha: indlela engqongqo yokungena kunye noqeqesho lwezakhono kwishishini luphuhlisa iqela lenkonzo ekumgangatho ophezulu.
