Imigangatho yokukhetha ivalve yaseTshayina kunye neendlela

Ngophuhliso olukhawulezayo lobugcisa boshishino, iivalvu zaseTshayina zisetyenziswa kakhulu kubunjineli, kwaye ukusebenza kwazo kunye nomgangatho kuchaphazela ngqo ukhuseleko, ukuthembeka kunye noqoqosho lweprojekthi iphela. Ke ngoko, ukukhethwa kweevalve zaseTshayina kuye kwaba yinkxalabo kumashishini amaninzi. Eli nqaku liza kuvela kwimigangatho yokukhetha ivalve yaseTshayina, iindlela kunye neminye imiba yengxoxo enzulu, ukukunceda ukhethe ngcono iimfuno zabo zobunjineli zevalve yaseTshayina. Okokuqala, imigangatho yokukhetha ivalve yaseTshayina 1. Iindidi zevalvu yaseTshayina kunye neenkcukacha Uhlobo kunye neenkcukacha zeevalvu zaseTshayina ziyimilinganiselo ephambili yokuthenga iivalvu zaseTshayina. Iindidi eziphambili zamaShayina ziyibhola, iivalve zeglowubhu, iivalve zesango, i-butterfly valves, iivalve ezilawulayo, njl. Ngoko ke, xa kuthengwa i-valve yaseTshayina, kufuneka sikhethe uhlobo olufanelekileyo lwee-valve zaseTshayina ngokweemfuno zangempela zeprojekthi. Ukongezelela, ukucaciswa kwee-valve zase-China ikakhulukazi kubandakanya i-valve yase-China, ukulinganiswa koxinzelelo, ububanzi beqondo lokushisa, njl njl. Xa kuthengwa i-valve yaseTshayina, kuyimfuneko ukuqinisekisa ukuba iinkcukacha ezikhethiweyo zihambelana neemfuno zobunjineli zokuqinisekisa ukusebenza okuqhelekileyo kwee-valve zaseTshayina. 2. Izinto zevalve yaseTshayina Izinto zeevalvu zaseTshayina zichaphazela ngokuthe ngqo ukuxhathisa ukubola, ukumelana nokunxiba, ukutywinwa kunye nezinye iipropathi zeevalvu zaseTshayina. Okwangoku, izixhobo zevalve yaseTshayina ezisetyenziswa ngokuqhelekileyo ziyintsimbi, intsimbi yekhabhoni, intsimbi engenanto, intsimbi yealloyi njalo njalo. Ekuthengeni i-valve yaseTshayina, kufuneka sikhethe izinto ezifanelekileyo ze-valve zaseTshayina ngokusingqongileyo kunye neempawu zeendaba zeprojekthi. 3. Ukusebenza kwevalve yaseTshayina Ukusebenza kweevalvu zaseTshayina kubandakanya ukutywinwa kokusebenza, ukusebenza kokuhamba, uhlengahlengiso kunye nokunye. Xa kuthengwa i-valve yaseTshayina, kufuneka sigxininise kwizalathisi zokusebenza kwee-valve zaseShayina ukuqinisekisa ukuba iivalve zaseTshayina ezikhethiweyo zinokuhlangabezana neemfuno zobunjineli. 4. Inkqubo yokuvelisa i-valve yaseTshayina Inkqubo yokuvelisa i-valve yaseTshayina ichaphazela ngokuthe ngqo umgangatho, ubomi benkonzo kunye nokuthembeka kweevalve zaseTshayina. Xa kuthengwa iivalvu zaseTshayina, kufuneka sinikele ingqalelo kwinkqubo yokwenziwa kweevalvu zaseTshayina kwaye sikhethe iivalvu zaseTshayina ezinenkqubo ebalaseleyo yokuvelisa. Okwesibini, indlela yokukhetha i-valve yaseTshayina 1. Bhekisela kwimigangatho yoshishino Xa uthengela i-valve yaseTshayina, unokubhekisela kwimigangatho efanelekileyo yelizwe kunye neshishini, njenge-GB/T 12220-2015 "indlela yokulungiselela uhlobo lwe-valve yaseChina", GB/T 12221-2017 "Ubude besakhiwo seValve yaseChina" njalo njalo. Le migangatho inemimiselo ecacileyo malunga nohlobo, ukucaciswa, izinto eziphathekayo, ukusebenza kunye neminye imiba ye-valve yaseTshayina, enokusetyenziswa njengesiseko sokubhekisela ekuthengeni i-valve yaseTshayina. 2. Qonda idumela lomenzi kunye nomgangatho wemveliso Ekuthengeni iivalve zaseTshayina, ukukhetha udumo oluhle kunye nabavelisi bomgangatho wemveliso. Uyakwazi ukuqonda igama umenzi kunye nomgangatho imveliso ngokusebenzisa inethiwekhi imibuzo, ukubonisana noontanga kunye nezinye iindlela zokuqinisekisa ukuba ukuthengwa ezikumgangatho ophezulu iivalvu Chinese. 3. Thelekisa ixabiso lemveliso kunye nokusebenza Xa kuthengwa i-valve yaseTshayina, kufuneka sithelekise ixabiso kunye nokusebenza kwabavelisi abahlukeneyo kunye neemodeli ezahlukeneyo zeevalve zaseTshayina, kwaye ukhethe i-valve yaseShayina engabizi kakhulu. Ngokuthelekisa, asifanele sinikele ingqalelo kuphela kwixabiso lemveliso, kodwa kwakhona sinikele ingqalelo kwizibonakaliso zezinto eziphathekayo, ukusebenza kunye nenkqubo yokuvelisa i-valve yaseChina. 4. Nika ingqalelo kwinkonzo emva kokuthengisa Ekuthengeni iivalve zaseTshayina, kufuneka sinikele ingqalelo kwinkonzo yomenzi emva kokuthengisa. Njengezixhobo zobunjineli, iivalve zaseTshayina zinokungaphumeleli ngexesha lokusetyenziswa kwaye zifuna ukulungiswa ngexesha. Ngoko ke, xa kuthengwa i-valve yaseTshayina, kuyimfuneko ukukhetha umenzi onenkonzo efanelekileyo emva kokuthengisa ukuqinisekisa ukusebenza okuqhelekileyo kweevalve zaseTshayina ngexesha lokusetyenziswa. Isishwankathelo Ukuthengwa kweevalvu zaseTshayina kubandakanya imiba emininzi, kubandakanywa iintlobo zevalve yaseTshayina kunye neenkcukacha, izixhobo, ukusebenza, iinkqubo zokuvelisa njalo njalo. Ekuthengeni iivalve zaseTshayina, ngokweemfuno zobunjineli, ukuqwalaselwa okubanzi kwezi zinto, khetha iivalve ezifanelekileyo zaseTshayina. Kwangaxeshanye, ekuthengeni iivalvu Chinese, kodwa kwakhona ingqalelo igama umenzi kunye nomgangatho imveliso, xa kuthelekiswa ixabiso imveliso kunye nokusebenza, kwaye ingqalelo inkonzo emva-intengiso. Kuphela ngale ndlela sinokuthenga iivalve zaseTshayina ezikumgangatho ophezulu ukuqinisekisa ukhuseleko, ukuthembeka kunye noqoqosho lweprojekthi.
