Intsimbi yentsimbi engatyiwa ngumhlwa ibangela kunye nezisombululo

Umhlwa wevalvu yensimbi engenastainless kunye nezisombululo Lo mgangatho uxela ukwakheka kweekhemikhali, iipropathi zoomatshini, iimfuno zobugcisa, ukuvavanywa kunye nokuhlolwa kokuphoswa kwensimbi engenasici kwiivalvu zenjongo jikelele. Lo mgangatho usebenza kwi-castings yensimbi engenasici efana neevalve zoxinzelelo, iiflange kunye nezixhobo zombhobho ezisetyenziselwa ubushushu obuphezulu kunye neendawo ezinobungozi. Umvelisi ophosayo uya kwenza uhlalutyo lwemichiza kwiziko ngalinye ukumisela umxholo ochaziweyo. Kuhlalutyo, iibhloko zokuvavanya ezigalelwe kwisithando somlilo esifanayo ziya kusetyenziswa. Xa ukusika ukusika kusenziwa isampuli, kufuneka kuthathwe ubuncinane kwi-6.5mrr: ngaphantsi komhlaba. Iziphumo zohlalutyo ziya kuhambelana neemfuno zeThebhile 1 kwaye zixelwe kuMfuni okanye ** yakhe. Uluhlu olu-1 Lo mgangatho uchaza ukubunjwa kweekhemikhali, iipropati zoomatshini, iimfuno zobugcisa, ukuvavanywa kunye nokuhlolwa kweentsimbi zensimbi ezingenasici kwiivalvu zenjongo jikelele. Lo mgangatho usebenza kwi-castings yensimbi engenasici efana ne-valve yoxinzelelo, ii-flanges kunye nezixhobo zombhobho ezisetyenziswa kwiqondo lokushisa eliphezulu kunye neendawo ezinobungozi. 2 Amaxwebhu ereferensi eqhelekileyo Imiqathango kula maxwebhu alandelayo iba yimiqathango yalo Mgangatho ngokubhekisele 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. Isampuli yendlela yokulinganisa i-chemical analysis ye-GB / T 222 yensimbi kunye nokuphambuka okuvumelekileyo kokugqitywa kokwakhiwa kweekhemikhali GB / T 223 (zonke iindawo) zentsimbi.

Kuhlalutyo, iibhloko zokuvavanya ezigalelwe kwisithando somlilo esinye kufuneka zisetyenziswe. Xa ukusika ukusika kusenziwa isampuli, kufuneka kuthathwe ubuncinane kwi-6.5mrr: ngaphantsi komhlaba. Iziphumo zohlalutyo ziya kuhambelana neemfuno zeThebhile 1 kwaye zixelwe kuMfuni okanye ** yakhe. 3.2.2.2 Uhlalutyo lweemveliso ezigqityiweyo Uhlalutyo lweemveliso ezigqityiweyo lunokwenziwa ngumfaki-sicelo ngokwalo, ukusuka kwisithando somlilo ngasinye, ibhetshi nganye okanye isampuli yokuphosa egqibeleleyo. Xa kusenziwa iisampulu zokusikwa, kufuneka ngokubanzi zithathwe ubuncinane ukusuka kwi-6.5mm ngaphantsi komhlaba, kwaye xa ubukhulu be-casting bungaphantsi kwe-12mm, indawo esembindini kufuneka ithathwe. Iziphumo zohlalutyo ziya kuhambelana namalungiselelo eThebhile 1, kwaye ukuphambuka okuvumelekileyo kohlalutyo kuya kuhambelana nemimiselo ye-GB/T222. Ukuphambuka okuvumelekileyo kokuhlalutya kwemveliso egqityiweyo akunakusetyenziswa njengesiseko sokwamkelwa kwefektri yokuphosa. 3.2.2.3 Uhlahlelo lweArbitration Indlela yesampulu yohlalutyo lweekhemikhali iyakulandela imigaqo ye-(}B/T 222, kwaye uhlahlelo lwe-arbitration lokwakheka kweekhemikhali luyakulandela imigaqo ye-GB/T 223. 3.3 IiPropati zoomatshini Iipropathi zomatshini zokuphosa ukuhambelana nemigqaliselo kwiThebhile 2. 3.4 Unyango olushushu Unyango lokushisa kufuneka luhlangabezane neemfuno zeThebhile 2, isithando somlilo sokushisa kunye nesixhobo sokushisa okuphezulu, ngokwemimiselo ye-GB / T 9452 ngokufanelekileyo ukulawula ukushisa kwesithando somlilo 3.5 Iimfuno zoMgangatho 3.5.1 Ubungakanani bokuphosa I-Castings iya kuhambelana neemfuno zemilo, ubungakanani kunye nokutenxa kwemizobo kunye neemodeli ezibonelelwe ngumenzi. Ukunyamezela ubunzima be-casting kuya kuhambelana ne-GB / T 11351. 3.5.2 Umphezulu we-casting Umphezulu we-castings uya kuhlolwa ngokuhambelana ne-JB / T 7927 kunye neemfuno zekhontrakthi yomyalelo. Akusayi kubakho ziphene ezingaphezulu njengesanti, ulusu lweoksidi kunye neentanda. 3.5.3 Ukulungiswa kweewelding 3.5.3.1 Iiwelders of the welding repair castings ziya kulupasa uviwo ngokweemfuno ze-(GB/T 15169) kwaye zibe nezatifikethi zemfundo ezingqinelanayo. Uvavanyo lwenkqubo yokuwelda luya kwenziwa ngokweemfuno ze-JB 4708. 3.5.3.2 Ukufakwa kunye nazo naziphi na iziphene zilandelayo akuvumelekanga ukuba zilungiswe: a) Iziphene ezingavumelekanga ukuba zilungiswe ngokwemizobo okanye ngokwekhontrakthi yoku-odola. ; b) Abo banemingxuma yobusi; c) Ukuvuza kovavanyo loxinzelelo lweemveliso ezigqityiweyo kunye nomgangatho awunakuqinisekiswa emva kokulungiswa kwe-welding; d) Amaxesha okulungisa i-welding yecandelo elifanayo aliyi kudlula amaxesha ama-2. 1 2 iphepha elilandelayo steel stainless steel stainless umhlwa umhlwa kunye nezisombululo Enye, intsimbi engenastainless valve umhlwa izizathu Uphando ukuba ivelufa steel stainless uyakwazi ukurusa, ungakwazi kuqala ukubeka ivelufa efanayo kwindawo eyahlukileyo ukuqinisekisa uthelekiso, xa sithetha ngokubanzi, ukuba intsimbi engenasici. ivalve ibekwe kwindawo eyomileyo, emva kwexesha elide, ivalve ayilungile nje entsha, kodwa akukho mhlwa, kodwa ukuba ivalve ibekwe kumanzi olwandle aqulethe ityuwa eninzi, hayi iintsuku ezimbalwa ziya kugqwala. Kuyabonakala ukuba ukuxhathisa kwe-corrosion kunye ne-rust resistance ye-valve yensimbi engenasici nayo kufuneka inqunyelwe ngokusetyenziswa kwendalo. Ukongeza, ukusuka kwiimpawu zevalve yensimbi engenasici ngokwayo, akusiyo umhlwa kuba kukho umaleko wefilimu ene-chromium etyebileyo ye-oxide phezu komhlaba ukukhusela ii-athomu ze-oksijini zangaphandle kunye nezinye iincinci ezibangelwa ukuhlaselwa komonakalo kwinto. ukuze ibe neempawu zomhlwa, kodwa xa ifilim yonakaliswe yimiba yokusingqongileyo, njengoko iiathom zeoksijini zingena kwi-ion yentsimbi yasimahla, ivalve yentsimbi engenasici iya kuvelisa umhlwa. Kukho izizathu ezininzi zokutshatyalaliswa kwefilimu yevalve yensimbi engenasici, ekhokelela kwirusi, ifilimu kunye nezinye izinto zentsimbi okanye uthuli lwe-electrochemical reaction, ngaxeshanye nomoya omanzi njengento ephakathi, ukwakheka komjikelo webhetri encinci, ukwenza umhlwa umphezulu steel stainless, unakho kwakhona insimbi stainless umphezulu ifilimu ngqo ukudibana ne acid, alkali kunye nezinye ulwelo ezonakalisayo, okubangelwa umhlwa, njl. Ngoko ke, ukuze intsimbi engenastainless ivalve umhlwa, ekusetyenzisweni kwemihla ngemihla kufuneka kwakhona ingqalelo kwi ukucocwa kwezinto, gcina umphezulu wevalve ucocekile. Izimbini, isisombululo se-valve yensimbi engenastainless Ke uqinisekisa njani ukuba ubuso bentsimbi buhlala buqaqambile kwaye abudlanga? Sanjing Valve Manufacturing Co., LTD. Iingcebiso zabasebenzi bobuchwephesha kunye nobuchwepheshe: 1. Kuyimfuneko ukuba ucoce kwaye uhlambulule i-decorative steel stainless surface rhoqo, ukususa iziqhotyoshelo kunye nokuphelisa izinto zangaphandle ezibangela ukuguqulwa. 2. Ummandla wolwandle kufuneka usebenzise i-316 insimbi engenasici, izinto ezingama-316 zinokuxhathisa ukubola kwamanzi olwandle. 3. Ukwakhiwa kweekhemikhali kwezinye iibhubhu zetsimbi ezingenasici kwiimarike azikwazi ukuhlangabezana nemigangatho yelizwe ehambelanayo, ukuya kuthi ga kwiimfuno ze-304 zezinto eziphathekayo. Ngoko ke, kuya kubangela i-rust, efuna ukuba umsebenzisi akhethe ngokucophelela ukwakhiwa kwemveliso yabakhiqizi abahloniphekileyo kunye neendawo zokwakha ingqalelo ukwenzela ukuthintela ukwakhiwa kwemikrwelo kunye nokungcola okuqhotyoshelweyo, ukwakhiwa kwensimbi engenasici phantsi kombuso wefilimu. Kodwa kunye nokwandiswa kwexesha, ulwelo lokuncamathisela okushiyekileyo ngokuhambelana nobomi benkonzo yefilimu, emva kokwakhiwa kwefilimu kufuneka isuswe xa ukuhlamba umphezulu, kunye nokusetyenziswa kwezixhobo zensimbi ezingenasici, kunye nokucoca isinyithi ngokubanzi izixhobo zoluntu, ukuze ungavumeli i-iron chips stick stick kufuneka ihlambuluke. Ingqalelo kufuneka ihlawulwe ukuze kuthintelwe amachiza okucoca ubunewunewu bemagnethi kunye nelitye ukuba angadibani nomphezulu wentsimbi engenasici, ukuba unxibelelwano kufuneka luhlanjwe kwangoko. Emva kokwakhiwa, i-detergent engathathi hlangothi kunye namanzi kufuneka isetyenziswe ukuhlamba i-samente, i-powder kunye nomlotha ofakwe phezulu.
