Inkqubo yoVavanyo lweMibhobho, iSicwangciso sokuCoca kunye nokuCoca

1. Iimeko kunye namalungiselelo oxinzelelo lovavanyo lombhobho wobugcisa

I.1.Inkqubo yemibhobho igqityiwe kwaye iyahambelana neemfuno zoyilo kunye nemimiselo.

I.2.Isebe, i-hanger kunye ne-pipe rack igqityiwe, kwaye ukufunyanwa kwe-ray flaw kufikelele ngokupheleleyo kwiinkcukacha zokuyila, kwaye inxalenye yovavanyo, i-weld kunye nezinye kufuneka ivavanywe ayipeyinti kwaye ifakwe.

I.3.I-gauge yoxinzelelo lovavanyo iqinisekisiwe, ukuchaneka kumiselwe kwi-1.5, kwaye ixabiso elipheleleyo letafile kufuneka libe yi-1.5 ukuya ku-2 amaxesha aphezulu oxinzelelo olulinganisiweyo.

I.4.Ngaphambi kovavanyo, inkqubo yokuvavanya, izixhobo kunye neziqhotyoshelwano aziyi kubandakanyeka kwinkqubo yokuvavanya, kwaye indawo yebhodi eyimfama isetyenziselwa ukusebenzisa i-lacquer emhlophe ye-lacquered mark kunye nerekhodi.

I.5.Amanzi okuvavanya kufuneka asetyenziswe ngamanzi acocekileyo, kwaye umxholo we-chloride ion emanzini akufanele udlule i-25 × 10-6 (25 ppm).

I.6.Umbhobho wexeshana wokuvavanya uqiniswa, kwaye ukhuseleko kunye nokuthembeka kufuneka kuhlolwe.

I.7.Khangela ukuba zonke iivalve kumbhobho zikwimeko evulekileyo, nokuba ngaba i-spacers zongezwa, kwaye i-valve core ye-valve iya kususwa, kwaye emva kokuba ukuhlanjululwa kunokwenziwa kwakhona.

2. Uvavanyo lombhobho wenkqubo

2.1.Uxinzelelo lovavanyo lombhobho ngamaxesha e-1.5 yoxinzelelo loyilo.

2.2. Xa umbhobho kunye nezixhobo zivavanywa njengenkqubo, uxinzelelo lovavanyo lombhobho lulingana okanye lungaphantsi koxinzelelo lovavanyo lwesixhobo, kwaye uxinzelelo lovavanyo lwesixhobo alukho ngaphantsi kwe-1.15 yoxinzelelo loyilo lombhobho, kwaye inokuvavanywa ngokwexinzelelo lovavanyo lwezixhobo.

2.3.WI-hen inkqubo ifakwe, umoya kufuneka uphelelwe, indawo yokukhupha umoya kufuneka ibe yindawo ephezulu yombhobho, kwaye yongeza ivalve yokukhupha.

2.4. Kwimibhobho eneeyantlukwano ezinkulu, uxinzelelo lwe-static lwe-test medium kufuneka lulinganiswe kuxinzelelo lovavanyo.Uxinzelelo lovavanyo lombhobho we-liquid kufuneka lube phantsi koxinzelelo kwindawo ephezulu, kodwa uxinzelelo oluphantsi kakhulu alufanele lugqithise amacandelo e-tube.

2.5. Xa uxinzelelo lucinezelekile, ukunyuswa kufuneka kuhambe kancinci, kwaye emva kokuba uxinzelelo lovavanyo lufikelelwe, lulawulwa nge-10 min, kwaye akukho deformation ngaphandle kokuvuza.Uxinzelelo lovavanyo lwehla kuxinzelelo loyilo, luyeke imizuzu engama-30, kwaye uxinzelelo aluwi, akukho kuvuza okufanelekileyo.

2.6. Emva kovavanyo, iplate eyimfama kufuneka isuswe ngexesha, kwaye amanzi abekwe, kwaye uxinzelelo olubi kufuneka luthintelwe xa lukhutshwe, kwaye alufanele lukhuphe amanzi.Xa ukuvuza kufunyenwe ngexesha lovavanyo, akufanele kuqhutywe, emva kokuphelisa isiphene, kufuneka kuhlolwe kwakhona.

2.7.Uvavanyo lokuvuza lwenziwa emva kokuvavanywa koxinzelelo, kwaye uvavanyo oluphakathi lusebenzisa umoya ocinezelweyo.

2.8. Uxinzelelo lovavanyo lokuvuza lwenzelwe ukuyila uxinzelelo, uvavanyo lokuvuza kufuneka lugxininise ekujongeni isigcwalisi, i-flange okanye i-threaded joints, i-valve ye-valve, i-valve yokukhupha, i-valve yokukhupha amanzi, njl., kunye nokuhlolwa kwe-ejenti yogwebu ngaphandle kokuvuza.

3. umbhobho wobugcisa wokucoca kunye nokucoca

3.1. Iimfuno zeteknoloji yenkqubo

3.1.1. Umbhobho wenkqubo kufuneka wahlulwe kwaye ucocwe (kubhekiswa kuwo njengokucocwa).

3.1.2. Indlela yokuvuthela inqunywe ngokweemfuno zokusetyenziswa kombhobho, inkqubo engcolileyo yendawo yokusebenza kunye nombhobho wangaphakathi unqunywe, kwaye ulandelelwano lokumisa iinwele luqhutyelwa ngokubanzi ngokuhambelana nomphathi, umbhobho wesebe. , kunye netyhubhu yokukhupha.

3.1.3. Ngaphambi kokuvuthela, isixhobo esingaphakathi kwenkqubo kufuneka sikhuseleke kwaye sisuse i-orifice plate, i-valve yokulungiswa kokucoca kunye nomzimba we-valve ehoxisiweyo, njl., ngokufanelekileyo, kunye nokunye okunjalo.

3.1.4. Xa uhlanjululwa, ukungcola kumbhobho akufanele kungene kwisixhobo, kwaye ukungcola okukhutshwa kwisixhobo akuyi kungena kumbhobho, i-valve flange yongezwa.

3.1.5. Ukuhlanjululwa kombhobho kufuneka kube nokuhamba okwaneleyo, kwaye uxinzelelo lokucoca akufanele ludlule uxinzelelo loyilo, kwaye izinga lokuhamba ngokuqhelekileyo alikho ngaphantsi kwe-20 m / s.Xa uhlanjululwa, sebenzisa isando sokhuni ukubetha ityhubhu, kwaye ugxininise kwi-weld kunye nezantsi kombhobho, kodwa ungalimazi umbhobho .

3.1.6. Isebe lombhobho kufuneka liqwalaselwe ngaphambi kokuvuthela, kwaye ukuchithwa kwe-hanger kufuneka kuqiniswe xa kuyimfuneko.

3.2. Ukucocwa kombhobho, indlela yokucoca

3.2.1. Ukucoca amanzi: Indawo yokusebenza ngumbhobho wenkqubo yamanzi.Ukuhlanjululwa kwamanzi kunokufikelela kwinqanaba eliphezulu lokuhamba okanye kungabi ngaphantsi kwe-1.5 m / s kwi-tube.Ifanelekile kumanzi angaphandle kunye nokungafihli kunye nokungena.Emva kokuba umbhobho uhlanjululwe, amanzi kufuneka aphelelwe ngexesha.

3.2.2.Ukucocwa komoya: Isixhobo sokusebenza sicocwa ngokuthe ngcembe ngamacandelo omoya axinanisiweyo kwimibhobho yerhasi.Ukuba udibana nevalve, kufuneka ususe i-flange yangaphambili kwi-docking board, uze uyibuyisele emva kokuba umbhobho uvuthelwe.Uxinzelelo akufanele ludlule isitya kunye noxinzelelo loyilo lombhobho, kwaye izinga lokuhamba akufanele libe ngaphantsi kwe-20 m / s.Ngethuba lokuhlanjululwa komoya, xa igesi yokukhupha igesi ingatshayi, i-port yokukhupha ifakwe kwi-port yokukhupha ukuvavanya i-lacquered target wood, kwaye akukho mhlwa, uthuli, umswakama kunye nolunye udoti kwi-plate target kwi-5 min.

3.2.3.Ukucoca ngomphunga: Indawo yokusebenza icocwa ngomphunga kumbhobho womphunga.Umphunga uyacocwa ngaphambi kokuba ityhubhu efudumeleyo icothe, emva koko iphole ngokwemvelo ukuya kutsho kwiqondo lobushushu eliqhelekileyo, emva koko uphakamise ityhubhu efudumeleyo, uphumeze ukucoca okwesibini, ngoko ke uphinda-phindo alukho ngaphantsi kwamaxesha amathathu.Irhasi ephumayo kwindawo yokucoca umphunga ijonge phezulu, kwaye uphawu lutsala amehlo.Umbhobho wokukhupha umbhobho akufanele ube ngaphantsi kobubanzi bombhobho wokucoca.Umgangatho ofanelekileyo: Iithagethi zokutshintshwa kabini ngamaxesha amabini alandelelanayo, njengamabala abonakala kwiso lenyama kwisayizi yepleyiti ekujoliswe kuyo ngaphantsi kwe-φ 0.6mm, ubunzulu bobunzulu yi-1 / cm2;ixesha lokucoca yimizuzu eli-15 (okt ezimbini Kwimeko yokupasa, igqithisiwe.
