Izinto zevalve yentsimbi, uyilo, iimfuno zokuhlola Iimfuno ngokubanzi zevalve yentsimbi Lo mgangatho uchaza uxinzelelo kunye nomgangatho wobushushu, izixhobo, iimfuno zoyilo, ukuhlolwa kunye novavanyo, ukuphawula kunye nokuhlolwa okungonakalisi kunye nokulungiswa kweevalvu zentsimbi. Ngaphakathi kwamaxabiso eklasi yoxinzelelo lwegama, umlinganiselo ophakathi phakathi koludwe lweqondo lobushushu okanye imilinganiselo yoxinzelelo inokumiselwa ngoguqulelo lomgca. Kodwa kwi-valve ene-flanged, indlela yokufakelwa kwe-linear ayivumelekanga ukumisela uxinzelelo oluqhelekileyo. Iqondo lokushisa elihambelana noxinzelelo olulinganisiweyo liqondo lokushisa elilinganisiweyo lendlu yoxinzelelo, efana neqondo lokushisa eliphakathi kulo. I-1 Uluhlu Lo mgangatho uchaza uxinzelelo kunye nokulinganisa ubushushu, izixhobo, iimfuno zokuyila, ukuhlolwa kunye nokuvavanya, ukuphawula kunye nokuhlolwa okungonakalisi kunye nokulungiswa kweevalve zetsimbi. Lo mgangatho usebenza kwizinto ezidweliswe kwiThebhile 1. Umzimba unokuphoswa, uphonswe kwaye udityaniswe, uxhulumaniso lwesiphelo lunokuthi lube ne-flanged, i-threaded and welded, kunye ne-clip-mounted and single-flanged valves. Lo mgangatho usebenza kuluhlu lweeparamitha zevalve: a) Uxinzelelo lwegama PN16 ~ PN760 iivalve, uxinzelelo lwe-PN760 * lufanelekile kwi-welding end valves; b) Ubungakanani begama abukho ngaphezu kwe-DN125. I-valve yokugqiba i-flange kunye ne-butt welding edibanisa i-valve ekupheleni; c) Iivalvu ezidityanisiweyo zokuphela kunye neevalvu eziphothiweyo ezinobukhulu obungadlulanga i-DN65: d) iivalvu eziphothiweyo ezineqondo lobushushu elingekho ngaphezulu kwe-540℃ kunye noxinzelelo lwegama olungekho ngaphezulu kwe-PN420; e) Izivalo ezijingayo ezinoxinzelelo lwegama PN16~PN25, iqondo lobushushu elilinganisiweyo lingekho ngaphezulu kwama-540℃ 2 Amaxwebhu ereferensi eqhelekileyo Le migaqo kula maxwebhu alandelayo iba yimiqathango yalo Mgangatho ngokubhekiselele kulo Mgangatho. Kwiingcaphulo zomhla, zonke izilungiso ezilandelayo (kungabandakanywa iimpazamo) okanye izilungiso azisebenzi kulo Mgangatho, nangona kunjalo, amaqela kwizivumelwano phantsi kwalo Mgangatho ayakhuthazwa ukuba ahlolisise ukusetyenziswa kweenguqulelo zala maxwebhu. Kwiimbekiselo ezingabhalwanga umhla, iinguqulelo zabo ziyasebenza kulo mgangatho.

Iivalvu zenqanaba loxinzelelo oluqhelekileyo oludibana iimfuno zalo mgangatho, ngaphandle kwezo zihlangabezana neemfuno ze-NDT ze-Appendix C valves, zityunjwe njengemigangatho yeklasi yoxinzelelo oluqhelekileyo kunye noxinzelelo lweqondo lokushisa njengoko kuchazwe kwi-3.1.1. 3.1.3 Iivalvu ezikumgangatho okhethekileyo woxinzelelo Iivalvu ezihlangabezana neemfuno ze-3.1.2 kwaye ezihlangabezana neemfuno ze-NDT zeSihlomelo C iivalvu zinemilinganiselo yobushushu boxinzelelo njengoko kuchaziwe kwiitheyibhile D.1L ukuya ku-D.12 kwiSihlomelo D. ayisebenzisi kwiivalvu eziphothiweyo. 3.1.4 Ivalve yeqondo eliphakathi Ngaphakathi kwamaxabiso eklasi yoxinzelelo lwegama, umlinganiselo ophakathi phakathi koludwe lweqondo lobushushu okanye ukulinganiswa koxinzelelo kunokumiselwa ngoguqulelo lomgca. Kodwa kwi-valve ene-flanged, indlela yokufakelwa kwe-linear ayivumelekanga ukumisela uxinzelelo oluqhelekileyo. 3.1.5 INdibano yee-welds iivalvu ezidityaniswe ngokupheleleyo okanye inxalenye enecastings, forgings, rods, plates okanye imibhobho iya kuhlangabezana nezi mfuno zilandelayo: a) Ukuwelda kunye nokuphathwa kobushushu kwee-welds kuya kuqhutywa ngokuhambelana nemimiselo ye-GB 150-1998 ; b) Ukuhlolwa kwe-Weld kunye nokwamkelwa kuya kuhambelana nemimiselo ye-GB 150-1998; c) Ezi mfuno zingentla azisebenzi ekutywinweni okanye ekudibaneni kwentsimbi, njengokuwelding izitywini ezibuyela umva, imisesane yokuhlala, iilugi zokuphakamisa kunye nezinto ezincedisayo.
