Isikhokelo esibanzi sokukhetha iivalvu zeglowubhu zeflange eziqhelekileyo zaseTshayina ezisekelwe kwiimfuno zobunjineli
1,Intshayelelo
Ivalve yeglowubhu yeFlange luhlobo lwevalvu esetyenziswa ngokuqhelekileyo, esetyenziswa ngokubanzi kwimimandla efana nepetroleum, imichiza, amandla, kunye nonikezelo lwamanzi. Ivalve yeglowubhu yomgangatho waseTshayina yivalvu eveliswe ngokwemigangatho yelizwe laseTshayina, eneempawu zesakhiwo esiphucukileyo, ukusebenza kakuhle kokutywina, kunye nobomi benkonzo ende. Kwinkqubo yokukhetha ubunjineli, indlela yokukhetha ivalve yeglowubhu yeglowubhu yaseTshayina efanelekileyo ngokweemfuno zobunjineli ibe ngumba ophambili. Eli nqaku liza kukunika isikhokelo esibanzi ekukhetheni iivalvu zeglowubhu zeflange zaseTshayina ukusuka kwimiba emininzi.
2,Ukuhlelwa kweevalvu zeglowubhu zeflange zaseTshayina
1. Ngokwendlela yolwakhiwo, inokwahlulwa ibe ziivalve zeglowubhu zohlobo lwe-wedge, iivalve zeglowubhu zohlobo lweblade, iivalve zeglowubhu ezinemisonto, njl.
Ngokwendlela yokudibanisa, inokwahlulwa ibe yi-flange uxhumano, uxhulumaniso lwe-welding ye-butt, uxhumano lwe-threaded, njl.
3. Ngokwendlela yokuqhuba, inokwahlulwa ibe ngamacandelo okuvalwa kombane, iivalve zokuvala zombane, iivalve zokuvala i-pneumatic, njl.
3,Izinto ekufuneka ziqwalaselwe xa ukhetha iivalvu zeglowubhu yeflange esemgangathweni yaseTshayina esekwe kwiimfuno zobunjineli
1. Indawo yokusebenza
Khetha imathiriyeli yevalvu ehambelanayo kunye nefom yesakhiwo esekelwe kuhlobo oluphakathi (njengamanzi, ioli, igesi, njl.) kunye nobushushu obuphakathi. Umzekelo, ubushushu obuphezulu, uxinzelelo oluphezulu, kunye nemithombo yeendaba ezonakalisayo, iivalve zeglowubhu zohlobo lwewedge kufuneka zikhethwe, kunye nezinto ezichasene nobushushu obuphezulu kunye nokubola kufuneka kukhethwe.
2. Idayimitha yegama kunye noxinzelelo lwegama
Khetha iivalve ezihlangabezana neemfuno ezisekelwe kwiiparamitha zokuyila zombhobho (ezifana nobukhulu obuqhelekileyo, uxinzelelo lwegama, njl.). Idayamitha yegama kunye noxinzelelo lwegama leevalvu zeglowubhu zeflange zaseTshayina ezinoluhlu oluthile, kwaye kufuneka kuqinisekiswe ukuba ivalve ekhethiweyo inokuhlangabezana neemfuno zobunjineli.
3. Indlela yoqhagamshelwano
Khetha ivalve yeglowubhu yeflange ehambelanayo yaseTshayina ngokwendlela yoqhagamshelo lombhobho. Ukuba uxhumano lwe-flange lufanelekile kwiimeko ezinobubanzi bombhobho omkhulu kunye noxinzelelo oluphezulu; Umdibaniso we-butt welding ifanelekile kwiimeko apho ububanzi bombhobho buncinci kwaye uxinzelelo luphantsi.
4. Indlela yokuqhuba
Khetha indlela efanelekileyo yokuqhuba ngokusekelwe kwindlela yokusebenza. Iivalve zokuvala ngesandla zifanelekile kwiimeko ezine-frequencies ephantsi yokusebenza; Iivalve zokuvala umbane kunye ne-pneumatic zifanelekile kwiimeko ezinomsebenzi ophezulu wokusebenza kunye nemigama emide.
5. Ukusebenza kokutywinwa
Khetha iivalvu ezisebenza kakuhle ngokutywinwa ngokweemfuno zobunjineli bomsebenzi wokutywina. Ungabhekisa kulwazi lobugcisa bomenzi wevalvu ukuqonda iiparamitha zokutywina zokusebenza kwevalve.
6. Ubomi benkonzo
Cinga ubomi benkonzo yevalve kwaye ukhethe ivalve enomgangatho othembekileyo kunye nokugcinwa lula. Ngokubanzi, iivalvu zeglowubhu zohlobo lwewedge zinobomi obude benkonzo.
7. Indawo yokufakela
Ngokweemfuno zendawo yokufakela, khetha iivalve ezithobela ukhuseleko, ukukhuselwa kwendalo kunye neminye imimiselo. Kwiindawo ezonakalisayo, izixhobo zevalvu ezinganyangekiyo kufuneka zikhethwe.
4,Ukuqukumbela
Xa ukhetha iivalvu zeglowubhu zeflange zaseTshayina, ingqwalasela epheleleyo kufuneka inikwe kwiimfuno zobunjineli ukuze kuqinisekiswe ukusebenza ngokukhuselekileyo, okuthembekileyo, kunye nokusebenza kakuhle kweevalvu. Ngelo xesha, ukuqonda amandla obugcisa kunye nenkonzo yokuthengisa emva kokuthengiswa kwabavelisi be-valve kunika iziqinisekiso zokuphunyezwa kakuhle kweprojekthi. Ndiyathemba ukuba eli nqaku lingakunika ireferensi eluncedo xa ukhetha iivalvu zeglowubhu zeflange zaseTshayina.
