Umbiko Wemakethe Yevaluzi Yokulawula uqukethe ulwazi oluningiliziwe mayelana nezinto ezithonya isidingo, ukukhula, amathuba, izinselele kanye nezingqinamba. Ihlinzeka ngolwazi oluningiliziwe mayelana nesakhiwo sezimboni zomhlaba wonke nezesifunda kanye namathemba. Ngaphezu kwalokho, lo mbiko uhlanganisa ucwaningo nentuthuko, ukwethulwa kwemikhiqizo emisha kanye nedatha yempendulo yomkhiqizo evela ezinkampanini ezihamba phambili ezimakethe zomhlaba nezasekhaya. Ukuhlaziywa okuhleliwe kunikeza ukumelwa okunemifanekiso kanye nokuhlukaniswa kwesithombe kwemakethe yamavalvu okulawula ngokwesifunda.
Umbiko wocwaningo lwemakethe ye-valve yomhlaba wonke: uhlobo lwe-valve (i-valve yesango, i-valve yeglobhu, i-diaphragm valve, i-valve yebhola, i-butterfly valve, i-valve yokuhlola, njll.), usayizi we-valve (ngaphansi kwe-intshi engu-1, intshi engu-1 kuya ku-6 amayintshi, 6 "25" , “50″ 25 kanye no-50 nangaphezulu), ingxenye (ivalvu, i-actuator nokunye), ukusetshenziswa kokuphela (uwoyela negesi, amanzi nokungcola, amandla namandla kagesi, imboni yamakhemikhali , Ukudla Nesiphuzo, Imithi nezinye) kanye isifunda (eNyakatho Melika, eYurophu, e-Asia Pacific, eMpumalanga Ephakathi nase-Afrika, eNingizimu Melika)- isibikezelo sika-2025
I-Bureau of Economic Analysis kanye ne-US Census Bureau ikhiphe umbiko ngoJuni 8, 2021, ithi imakethe yaseMelika iyasimama. Umbiko uphinde wachaza ukusimama kohwebo lwamazwe ngamazwe e-US ngoJulayi 2021. Ngo-April 2021, ukuthunyelwa kwezwe kwamanye amazwe kwafinyelela ku-$300 billion, kwakhuphuka amaRandi ayizigidi eziyizinkulungwane ezingu-13.4. Ngo-Ephreli 2021, ukuthengwa kwamanye amazwe kwakungama-dollar ayizigidi eziyizinkulungwane ezingama-294.5, kwakhuphuka amabhiliyoni angama-17.4. I-COVID-19 isalokhu ikhathaza kakhulu umnotho womhlaba, njengoba kufakazelwa ukwehla konyaka nonyaka ekuthengisweni kwempahla e-US kusuka ngo-Ephreli 2020 kuya ku-Ephreli 2021 kanye nokwenyuka kokungeniswa kwamanye amazwe ngasikhathi sinye. Imakethe idonsa kanzima ukuze ilulame. Noma kunjalo, lokhu kusho umthelela oqondile embonini yezokunakekelwa kwempilo/ICT/ yamakhemikhali, okuholela emakethe enkulu yamavalvu okulawula.
I-valve yokulawula iyithuluzi lomshini elilawula ukugeleza koketshezi ohlelweni ngokushintsha ubukhulu bomzila wokugeleza. Ngaphezu kwalokho, balawula futhi balawule izimo ezihlukahlukene, njengezinga, izinga lokushisa nokucindezela, ngokusekelwe kumasignali atholwe ohlelweni lokulawula. Ukuvulwa okuyingxenye noma okugcwele noma ukuvala kwe-valve yokulawula kwenziwa yi-actuator. Izingxenye eziyinhloko ze-valve zihlanganisa umzimba we-valve, isembozo se-valve, ipuleti le-valve, isihlalo, izingxenye zangaphakathi ze-valve, isiqu, ipulaki nokunye. Ama-valve okulawula asetshenziselwa ukusebenza ku-oyela negesi, amanzi namanzi angcolile, amakhemikhali, ukudla nesiphuzo, i-Marine, amandla nezimboni zamandla.
Izinto eziqhuba ukukhula kwemakethe yama-valve okulawula ukwanda kokutshalwa kwezimali embonini yamanzi namanzi angcolile kanye nokwakhiwa nokuthuthukiswa kwezimboni zamandla enuzi. Imboni yokuhlanza amanzi kanye namanzi angcolile ihlanganisa izinqubo ezihlukahlukene zokwelashwa kwamakhemikhali noma ngokomzimba kanye nezinqubo zokwelashwa kwamanzi angcolile zebhayoloji ezisetshenziselwa ukususa ukungcola nokungcola okuyingozi njengesulfure, ama-nitrate namagciwane emanzini. E-Chile, cishe u-99.97% wabantu babekwazi ukufinyelela ezikhungweni zokuhlanza indle ngo-2017, ngokusho kwe-Organisation for Economic Cooperation and Development (OECD). Ngaphezu kwalokho, bekunezitshalo zokuhlanza indle eziyi-14,748 e-United States ngo-2017, ngokusho kwekhadi lombiko wengqalasizinda eshicilelwe yi-American Society of Civil Engineers. Ngaphezu kwalokho, isidingo sezitshalo zokuhlanza indle kulindeleke ukuthi senyuke ngamaphesenti angama-23 ngo-2032, nokutshalwa kwezimali okulinganiselwa ku-271 billion yuan. Lezi zinguquko ziye zaholela ekwandeni kokusetshenziswa kwamavalvu okulawula, njengoba esiza ukulawula kangcono nokuqapha ukugeleza, udaka namakhemikhali ezimbonini zamanzi kanye namanzi angcolile.
Ngezinjongo zocwaningo, imakethe yama-valve okulawula umhlaba wonke ihlukaniswe ngohlobo lwe-valve, usayizi we-valve, ingxenye, ukusetshenziswa kokuphela kanye nesifunda. Ngohlobo lwamavalvu, imakethe yomhlaba wonke ihlukaniswe ngamavalvu esango, amavalvu embulunga, amavalvu e-diaphragm, ama-valve ebhola, ama-butterfly valve, ama-valve okuhlola, njll. Imakethe yomhlaba wonke ihlukaniswe ngosayizi wamavalvu ukuze ibe ngaphansi kuka-1″, 1″ kuya ku-6″, 6″ kuya ku-25″, 25″ kuya ku-50″ no-50″ nangaphezulu. Imakethe yomhlaba wonke ihlukaniswe izingxenye ngemizimba yama-valve, ama-actuator, njll. Imakethe yama-valve okulawula umhlaba wonke ihlukaniswe ngokusetshenziswa kokugcina kube uwoyela neGesi, ukuhlanza amanzi namanzi angcolile, Amandla Namandla, amakhemikhali, Ukudla Nesiphuzo, imithi, njll. esifundeni, imakethe ihlukaniswe eNyakatho Melika, eYurophu, e-Asia Pacific, Middle East & Africa, naseNingizimu Melika.
Ngokusekelwe ekuhlaziyweni komthelela we-COVID-19: Sihlaziye amathrendi embonini kumongo we-COVID-19. Sihlaziye umthelela we-COVID-19 ochungechungeni lwemikhiqizo ngokusekelwe ezimakethe ezikhuphuka nomfula. Sihlaziye umthelela we-COVID-19 ezifundeni ezihlukene nasemazweni abalulekile. Iveza umthelela we-COVID-19 ekuthuthukisweni kwesikhathi esizayo komkhakha.
Isikhathi sokuthumela: May-18-2022
