Ngokukhula kophuhliso lwecandelo lemizi-mveliso, iivalvu zaseTshayina zoxinzelelo oluphantsi zisetyenziswa kakhulu kumashishini amaninzi kwaye ziye zaba yinxalenye ephambili kwinkqubo yothutho lwamanzi. Iivalve ezikumgangatho ophezulu ophantsi woxinzelelo e-China azinakwahlulwa kwinkqubo yokuvelisa ngokungqongqo kunye nabavelisi abaziingcali. Eli nqaku liza kukusa kubenzi bevalvu yoxinzelelo oluphantsi lwaseTshayina, ukuqonda okunzulu kwenkqubo yokuvelisa ivalvu yoxinzelelo oluphantsi lwaseTshayina, uzive ukuzalwa komgangatho.
I. Isishwankathelo somenzi
Abavelisi bevalvu yoxinzelelo oluphantsi lwaseTshayina banamava oshishino olutyebileyo kunye nobuchwepheshe obuchwephesha, ukusuka ekukhethweni kwezinto ezikrwada, inkqubo yokuvelisa, ukuvavanywa komgangatho kunye neminye imiba yolawulo olungqongqo, ukuqinisekisa ukuba ivalve yoxinzelelo oluphantsi lweTshayina inomgangatho obalaseleyo kunye nokusebenza. Ukongeza, abavelisi bakwagxile ekuyilweni kwemveliso kunye nophando kunye nophuhliso, kwaye bahlala bephucula ubume bemveliso kunye nokuphucula ukusebenza kwemveliso ukuhlangabezana notshintsho olwenyukayo kwintengiso kunye neemfuno zabathengi.
Okwesibini, iimfihlo zenkqubo yemveliso
1. Ukukhethwa nokuthengwa kwemathiriyeli ekrwada
Iivalvu ezikumgangatho ophezulu zaseTshayina azinakwahlulwa kwizinto ezikumgangatho ophezulu. Abavelisi baya kujonga ngokungqongqo ababoneleli ngempahla ekrwada ngokweemfuno zemveliso, kwaye baphuhlise imigangatho engqongqo yokwamkelwa kwemathiriyeli ekrwada. Umgangatho wezinto eziluhlaza uchaphazela ngokuthe ngqo ukusebenza kunye nobomi beevalvu zoxinzelelo oluphantsi lwaseTshayina.
2. Inkqubo yokuvelisa kunye nezixhobo
Abavelisi bamkela iteknoloji yemveliso ephezulu kunye nezixhobo, ukusuka kwi-blanking, i-welding, i-machining, indibano, uvavanyo kunye namanye amakhonkco, ukuqinisekisa ukuchaneka kunye nomgangatho weemveliso. Kwinkqubo yokuvelisa, silandela ngokungqongqo imigangatho efanelekileyo kunye neenkcukacha zokuqinisekisa ukuba inkqubo nganye ingqongqo kwaye inokwethenjelwa.
3. Ukuhlolwa komgangatho kunye nolawulo
Umenzi uye wamisa amakhonkco okuhlola umgangatho amaninzi kwinkqubo yokuvelisa ukuqinisekisa ukuba umgangatho wemveliso uyalawuleka. Ukusuka kwimiba yokuhlolwa kwezinto ezikrwada, ulawulo lwenkqubo, kunye nokuhlolwa kwemveliso egqityiweyo, sinokwenza iileya zokuhlola ukuqinisekisa ukuba yonke ivalve yoxinzelelo oluphantsi e-China ihlangabezana neemfuno eziphezulu.
Okwesithathu, ngqina ukuzalwa komgangatho
IntoIvalve yoxinzelelo oluphantsi lwaseTshayina abavelisi, hayi kuphela unokuqonda inkqubo yemveliso, kodwa unokuziva ngokobuqu ukuzalwa umgangatho. Apha, unokungqina ngawakho amehlo ukuba izinto ezikrwada ziye zaguqulwa njani zaba kumgangatho ophakamileyo waseTshayina woxinzelelo oluphantsi emva kwenkqubo engqongqo. Ikhonkco ngalinye lemveliso libonisa ukuzingisa komenzi womgangatho kunye noxanduva lwabathengi.
Ngamafutshane, ukungena kubenzi bevalvu yoxinzelelo oluphantsi lwaseTshayina, hayi nje ukuba ungaqonda nzulu inkqubo yemveliso yeevalvu zaseTshayina ezisezantsi, kodwa unokungqina ukuzalwa komgangatho. Khetha umgangatho ophezulu we-low-pressure valves evela e-China, ukulawula umgangatho ovela kumthombo, kwaye unikeze isiqinisekiso esiqinileyo sokusebenza okuzinzileyo kunye nokukhuselekileyo kwintsimi yezoshishino.
