Uhlalutyo kunye noNyango lokuvuza kwangaphakathi kunye nokuvuza kwangaphandle kweeValve ze-Cryogenic

1. Ukuvuza kwangaphakathi kwevalve ye-cryogenic:

Uhlalutyo:Ukuvuza kwangaphakathi kwevalve yobushushu obuphantsi kubangelwa ikakhulu kukunxiba okanye ukuguqulwa kwendandatho yokutywina.Ngexesha lokusebenza kwenqanaba leprojekthi, kusekho ukungcola okuncinci okufana nesanti kunye ne-welding slag kumbhobho, oya kubangela ukuguga komphezulu wokutywina wevalve xa ivalve ivuliwe okanye ivaliwe.

Unyango:Emva kokuba ivalve ikwindawo yovavanyo loxinzelelo kunye nofakelo, ulwelo olushiyekileyo kunye nokungcola kumzimba wevalvu kufuneka kucocwe.Ngoko ke, imilinganiselo yokugcinwa kwendawo enikezelwa ngumenzi kunye nemibandela efuna ingqalelo kuvavanyo lwendawo kufuneka idityaniswe ngexesha lokwakha.Yazisa indawo kwaye ulawule ngokungqongqo umgangatho ukuququzelela imveliso, ukusebenza kunye nokugcinwa kweprojekthi kwixesha elizayo.

2. Ukuvuza kwevalve ye-cryogenic:

Uhlalutyo:Izizathu zokuvuza kweevalvu ze-cryogenic zinokuhlelwa kwezi zizathu zine zilandelayo:

1. Umgangatho wevalve ngokwawo awulungile ngokwaneleyo, kunye ne-blisters okanye i-shell cracks;

2. Ngethuba lenkqubo yokufakela, xa i-valve ixhunywe kwi-flange esetyenziselwa umbhobho, ngenxa yezinto ezahlukeneyo zokudibanisa i-fasteners kunye ne-gaskets, emva kokungena kwi-medium kwipayipi, kwindawo yokushisa ephantsi, izinto ezahlukeneyo ziyancipha ngokwahlukileyo. , okuphumela ekuphumleni;

3. Indlela yokufaka ayilunganga;

4. Ukuvuza kwisiqu sevalve kunye nokupakishwa.

 Indlela yokucubungula imi ngolu hlobo lulandelayo:

1. Ngaphambi kokuba isaziso somyalelo sikhutshwe, imizobo kunye noyilo olunikezelwe ngumenzi kufuneka luqinisekiswe kwaye lugqitywe ngexesha, kwaye umphathi wefektri kufuneka anxibelelane ngexesha.Izinto ezibonakalayo ezingenayo kufuneka zihlaziywe ngokungqongqo, kwaye i-RT, UT, PT kufuneka iqhutywe ngokweemfuno zobugcisa.ukuhlolwa, kunye nokwenza ingxelo ebhaliweyo.Nika ishedyuli yemveliso eneenkcukacha.Kwinkqubo yemveliso yexesha elizayo, ukuba akukho meko zikhethekileyo, imveliso kufuneka iqhutywe ngokungqongqo ngokuhambelana neshedyuli kunye nomgangatho oqinisekisiweyo kunye nobuninzi, kwaye umsebenzi wokuhlola ngokungqongqo kufuneka uqhutywe ngaphambi kokushiya i-factory.

2. Ivalve ephawulwe ngecala lokuhamba kufuneka inike ingqalelo kuphawu lwendlela yokuqukuqela kumzimba wevalvu.Ukongeza: Kwinkqubo, kubaluleke kakhulu ukulawula ixesha lokuqala lokupholisa i-valve ukwenzela ukuba i-valve ikwazi ukupholisa ngokupheleleyo.Kuyimfuneko ukujonga rhoqo ukuba udonga lwangaphakathi lwe-valve lunokuqhekeka, i-deformation kunye ne-corrosion yendawo yangaphandle, ngakumbi kwiqondo lokushisa eliphantsi.I-valve ye-medium ixhomekeke ngakumbi ekwandiseni i-thermal kunye nokunciphisa.Kwi-valve phantsi kweemeko ezinzima ezifana ne-cavitation, kuyimfuneko ukuba kuqinisekiswe amandla ayo okunyamezela, ukushisa okuphantsi kunye nokuxhatshazwa kokugqoka.
