Ingxelo yeMarike yeValve yoLawulo iqulethe ulwazi oluneenkcukacha kwizinto ezinefuthe kwimfuno, ukukhula, amathuba, imingeni kunye nemiqobo. Ibonelela ngeenkcukacha ezithe kratya malunga nolwakhiwo lwemizi-mveliso yehlabathi neyengingqi kunye namathemba. Ukongeza, ingxelo ibandakanya uphando kunye nophuhliso, ukuqaliswa kwemveliso emitsha kunye nedatha yempendulo yemveliso evela kwiinkampani eziphambili kwiimarike zehlabathi nezendawo. Uhlahlelo olucwangcisiweyo lubonelela ngokumelwa komzobo kunye nokwahlulwa komzobo kwimarike yesivalo solawulo ngokwengingqi.
Ingxelo yophando lwemarike yevalve yolawulo lwehlabathi: uhlobo lwevalve (ivalve yesango, ivalve yeglowubhu, ivalve yediaphragm, ivalve yebhola, ivelufa yebhabhathane, ivalve yokukhangela, njl.), ubungakanani bevalve (ngaphantsi kwe-intshi e-1, i-intshi e-1 ukuya kwi-intshi ezi-6, i-6 "25" , “50″ 25 kunye nama-50 nangaphezulu), icandelo (ivalve, i-actuator kunye nezinye), ukusetyenziswa kwesiphelo (i-oyile negesi, amanzi kunye namanzi amdaka, amandla kunye namandla ombane, ishishini lemichiza, ukutya nesiselo, amayeza kunye nabanye) ummandla (kuMntla Melika, iYurophu, iAsia Pacific, uMbindi Mpuma kunye neAfrika, uMzantsi Merika)- 2025 uqikelelo
I-Bureau yoHlahlelo lwezoQoqosho kunye ne-US Census Bureau ikhuphe ingxelo nge-8 kaJuni ka-2021, isithi imakethi yase-US iyachacha. Ingxelo iphinde yachaza ukubuyiswa korhwebo lwamazwe ngamazwe e-US ngoJulayi 2021. Ngo-Epreli 2021, ukuthunyelwa kwelizwe kumazwe angaphandle kufikelele kwi-300 yeebhiliyoni zeedola, ukuya kwi-13.4 yeebhiliyoni zeedola. Ngo-Epreli ka-2021, izinto ezithunyelwa ngaphandle bezingama-294.5 eebhiliyoni zeedola, zinyuke ngeebhiliyoni zeedola ezili-17.4. I-COVID-19 iseyeyona nto ixhalabisayo kuqoqosho lwehlabathi, njengoko kungqinwa kukwehla konyaka enyakeni kwimpahla ethunyelwa ngaphandle e-US ukusuka ku-Epreli wama-2020 ukuya ku-Epreli ka-2021 kunye nokonyuka kwezinto ezithunyelwa ngaphandle kwangelo xesha linye. Imarike ngokucacileyo iyasokola ukubuyisela. Nangona kunjalo, oku kuthetha impembelelo ethe ngqo kukhathalelo lwempilo / kwi-ICT/ kushishino lweekhemikhali, okukhokelela kwimarike enkulu yeevalvu zolawulo.
Ivalve yolawulo sisixhobo somatshini esilawula ukuhamba kolwelo kwinkqubo ngokuguqula ubungakanani bomjelo wokuhamba. Ukongezelela, zilawula kwaye zilawula iimeko ezahlukeneyo, ezifana nenqanaba, izinga lokushisa kunye noxinzelelo, ngokusekelwe kwiimpawu ezifunyenwe kwinkqubo yokulawula. Ukuvula inxalenye okanye epheleleyo okanye ukuvalwa kwevalve yokulawula kwenziwa yi-actuator. Ezona ndawo ziphambili zevalvu zibandakanya umzimba wevalvu, isigqubuthelo sevalvu, ipleyiti yevalvu, isihlalo, amalungu angaphakathi evalve, isiqu, iplagi njalo njalo. Iivalvu zokulawula zisetyenziselwa ukusebenza kwi-oyile kunye negesi, amanzi kunye namanzi amdaka, iikhemikhali, ukutya kunye nesiselo, iMarine, amandla kunye namandla amashishini.
Imiba eqhuba ukukhula kwemarike yevalvu yolawulo kukunyuka kotyalo-mali kushishino lwamanzi namanzi amdaka kunye nolwakhiwo kunye nophuculo lwemizi-mveliso yamandla enyukliya. Ushishino lokucocwa kwamanzi kunye namanzi amdaka lubandakanya iinkqubo ezahlukeneyo zonyango lwekhemikhali okanye lomzimba kunye neenkqubo zokucocwa kwebhayoloji yamanzi amdaka asetyenziselwa ukususa ungcoliseko kunye nezingcolisi eziyingozi ezifana nesulfure, i-nitrate kunye neebhaktheriya emanzini. E-Chile, malunga ne-99.97% yabemi babenokufikelela kwiindawo zokucocwa kwamanzi amdaka ngo-2017, ngokutsho koMbutho we-Economic Cooperation and Development (OECD). Ukongeza, bekukho i-14,748 yezityalo zokucoca amanzi amdaka e-United States kwi-2017, ngokwekhadi lengxelo yeziseko ezingundoqo epapashwe yi-American Society of Civil Engineers. Ukongeza, imfuno yezityalo zokucocwa kwamanzi amdaka kulindeleke ukuba inyuke ngeepesenti ezingama-23 ngo-2032, kunye notyalo-mali oluqikelelwayo lwe-yuan ye-271 yebhiliyoni. Olu phuhliso lukhokelele ekunyukeni kokusetyenziswa kweevalvu zokulawula, njengoko zinceda ukulawula ngcono nokubeka iliso ukuhamba, udaka kunye neekhemikhali kumashishini amanzi namanzi amdaka.
Ngeenjongo zophando, imarike yevalvu yolawulo yehlabathi yahlulwe ngohlobo lwevalvu, ubungakanani bevalvu, icandelo, ukusetyenziswa kwesiphelo kunye nommandla. Ngohlobo lwevalvu, imarike yehlabathi yahlulwe yaba ziivalvu zesango, iivalvu zeglowubhu, iivalvu zediaphragm, iivalvu zebhola, iivalvu zebhabhathane, iivalve zetshekhi, njl. njl. 6″ ukuya 25″, 25″ ukuya 50″ kunye 50″ nangaphezulu. Imarike yehlabathi yohlulwe ngamacandelo abe ngamaqumrhu evalvu, ii-actuator, njl. njl. Imarike yevalvu yolawulo yehlabathi yahlulwe ngokusetyenziswa kokuphela kwi-oyile negesi, amanzi kunye nonyango lwamanzi amdaka, Amandla naMandla, iikhemikhali, Ukutya & nesiselo, amayeza, njl. kwingingqi, imakethi yohlulwe kuMntla Merika, iYurophu, iAsia Pacific, uMbindi Mpuma kunye neAfrika, kunye noMzantsi Merika.
Ngokusekwe kuHlahlelo lwempembelelo ye-COVID-19: Sihlalutye iintsingiselo zeshishini kumxholo we-COVID-19. Sihlalutye ifuthe le-COVID-19 kwikhonkco lemveliso ngokusekwe kwiimarike ezinyukayo nezisezantsi. Sihlalutye ifuthe le-COVID-19 kwimimandla eyahlukeneyo kunye namazwe aphambili. Isalatha ifuthe le-COVID-19 kuphuhliso lwekamva loshishino.
