China amanyathelo ufakelo ivelufa esangweni ingcaciso eneenkcukacha: indawo ufakelo, isalathiso kunye nezilumkiso

China isango ufakelo ivelufa amanyathelo ingcaciso eneenkcukacha: indawo ufakelo, ulwalathiso kunye nezilumkiso China isango ivelufa sisixhobo sokulawula ulwelo ngokuqhelekileyo esetyenziswa, isakhiwo salo elula, ukutywina elungileyo kunye nezinye iingenelo kuyenza isetyenziswe ngokubanzi petroleum, imichiza, metallurgy, amandla ombane kunye namanye amashishini. indawo yokulawula ulwelo. Amanyathelo okufakela afanelekileyo ayimfuneko ukuqinisekisa ubomi benkonzo kunye nokusebenza kweevalve zesango laseTshayina. Eli nqaku liza kwazisa amanyathelo ofakelo kunye nezilumkiso zevalve yesango laseChina ukusuka kwindawo yokujonga. 1. Ukugqiba indawo yofakelo Xa ukhetha indawo yokufakela, le miba ilandelayo kufuneka iqwalaselwe: (1) Ukudibanisa okulula kunye nombhobho, ukugcinwa lula kunye nokulungiswa. (2) Gwema ukungcangcazela kunye nokothuka ukuthintela ukuchaphazela ubomi benkonzo kunye nokusebenza kwevalve. (3) Kuphephe ukuchanabeka elangeni okanye kwindawo erhabaxa ukuthintela ukuguga kunye nomonakalo kwizixhobo zesivalo. 2. Ukugqiba isalathiso sofakelo Xa ufaka i-valve yesango laseTshayina, kufuneka kulandelwe la manyathelo alandelayo: (1) Beka i-valve kwindawo echazwe kwangaphambili kwaye uqinisekise ukuba umgca ophakathi we-valve uhambelana nomgca ophakathi wombhobho. (2) Sebenzisa umgangatho ukujonga ukuba ivalve ikumgangatho, kwaye uyilungise ukuba ayinjalo. (3) Qhagamshela ivalve kunye nombhobho ngoqhagamshelo olunentambo okanye ngewelding. 3. Nika ingqalelo kwiinkcukacha zofakelo (1) Ngethuba lenkqubo yokufakela, ingqwalasela kufuneka ihlawulwe kwisalathiso se-valve ukuqinisekisa ukuba ukuhamba kwe-medium kuhambelana nesalathiso esiboniswe yi-valve arrow. (2) Xa udibanisa imibhobho kunye neevalvu, kufuneka kusetyenziswe izitywina ezifanelekileyo, kwaye uqinisekise ukuba unxibelelwano luqinile ukuthintela ukuvuza. (3) Ngethuba lenkqubo yokufakela, ingqalelo kufuneka ihlawulwe kwindlela yokusebenza kunye nendlela yokulawula ukuhamba kwevalve ukuqinisekisa ukusetyenziswa okuchanekileyo kunye nokugcinwa kwevalve. 4. Nika ingqalelo kukhuseleko Xa ufaka iivalve zesango laseTshayina, le mibandela yokhuseleko ilandelayo kufuneka ithathelwe ingqalelo: (1) Kwinkqubo yofakelo, kufuneka unxibe izixhobo ezikhuselayo, ezinjengeeglavu, izibuko, njl. njl. (2) Xa uqhaqha. okanye ukutshintsha iindawo zevalvu, umbane okanye unikezelo lomoya kufuneka lucinywe kuqala ukuthintela iingozi. (3) Ngethuba lenkqubo yokufakela, kufuneka kuthathelwe ingqalelo ukukhusela i-valve ukuba ingachaphazeleki okanye yonakaliswe yimikhosi yangaphandle, ukwenzela ukuba ingachaphazeli ubomi benkonzo kunye nokusebenza kwevalve. Ngamafutshane, inkqubo yofakelo echanekileyo yevalve yesango laseChina ibalulekile ukuqinisekisa ubomi benkonzo kunye nokusebenza kwevalve yesango laseChina. Xa ufaka iivalve zesango laseTshayina, nikela ingqalelo kwindawo yokufakela, isalathiso kunye neenkcukacha, kwaye uthobele imimiselo yokhuseleko olufanelekileyo kunye neenkqubo zokusebenza. Ndiyathemba ukuba inkcazo eneenkcukacha yamanyathelo ofakelo lwevalvu yesango laseTshayina kweli nqaku inokukunika ireferensi kunye noncedo.
