Ukusetyenziswa kwevalve yobhedu kuchaphazela yonke imihla ebomini bethu, xa sivula i-faucet ukusela amanzi okanye sivula umbhobho wokucima umlilo ukunkcenkceshela umhlaba wasefama, thina kunye neevalve zobhedu sibandakanyeka ekusebenzisaneni, umbhobho uyagxadazela, kwaye emva kwayo yonke into. zibe neentlobo ngeentlobo zeevalvu zobhedu ezibambelela kuzo.

Ukuphuhliswa kwevalve yobhedu kuhambelana ngokusondeleyo nophuhliso lwenkqubo yokuvelisa ishishini.Kumaxesha amandulo, abantu ukwenzela ukulawula ukuhamba kwemilambo okanye imilambo, ukusetyenziswa kwamatye amakhulu okanye iziqu zokuthintela ukuhamba kwamanzi okanye ukutshintsha indlela yokuhamba kwamanzi.Kwasekupheleni kwexesha emfazweni States, Qin Shu County prefect Li Bing (ukuzalwa nokufa akwaziwa) iye ethafeni Chengdu wagawula amaqula ityuwa, khupha ityuwa decoction.Thatha i-halogen, i-bamboo efanelekileyo yetyhubhu ye-halogen, efakwe kwi-casing, ezantsi ityhubhu ukuya eluswini lokuvula nokuvalwa kwevalve yobhedu, umgqomo unokuphoswa ngaphandle kwenani leemele, nkqo enkulu. isakhelo somthi, kunye ne-windlass, i-car plate extraction brine Ekupheleni kwevalve yobhedu yeplanga yobhedu yokuthintela ukuvuza, umntwana emaquleni kwityuwa ukuya kwityuwa.

Iivalvu zebhola zobhedu

I-Egypt kunye nempucuko yamaGrike yenze iindidi ezininzi zokuqala zeevalvu zobhedu zokunkcenkceshela izityalo njalo njalo.Nangona kunjalo, kuyamkelwa ngokubanzi ukuba abantu bamandulo baseRoma baphuhlisa inkqubo yamanzi entsonkothileyo yokunkcenkceshela izityalo, besebenzisa ivalve yobhedu yeplagi kunye nevalve yobhedu yokutshixa ukuthintela ukuhamba kwamanzi.

Ngexesha le-Renaissance, ukusetyenziswa kweevalve zobhedu kumagcisa kunye nabaqambi beDa Vinci bayile imijelo, iiprojekthi zokunkcenkceshela kunye nezinye iiprojekthi ezinkulu zenkqubo ye-hydraulic, uninzi lwezisombululo zakhe zobugcisa zisekhona.Emva koko iYurophu ngenxa yokuphuhliswa kobugcisa boqeqesho kunye noomatshini bamanzi, iimfuno zevalve yobhedu zanda ngokuthe ngcembe, ngoko ke ukudala i-valve yobhedu kunye ne-aluminium yobhedu, i-valve yobhedu yayikwinkqubo yesinyithi.

Imbali yanamhlanje yoshishino lwevalvu yobhedu ihambelana nenguqu kwezoshishino, ngobunzulu benguqu kwezoshishino.Ngo-1705 iNewcomb yavelisa injini yokuqala yomphunga, ukusebenza kwe-injini yomphunga kwiimfuno zolawulo.I-1769 watt yenza i-injini yomphunga ukuze ivalve yobhedu ingene ngokusesikweni kwishishini loomatshini, uninzi lwe-injini yomphunga isebenzisa iivalvu zobhedu zeplagi, iivalvu zobhedu zokhuseleko, iivalve zobhedu zokujonga kunye neevalvu zobhedu zebhabhathane.

Iivalvu zesango zobhedu

Ukuveliswa komphunga kukuqala kwenani elikhulu lezicelo kwishishini levalve yobhedu.Ukususela kwinkulungwane ye-18 ukuya kwinkulungwane ye-19, i-injini yomphunga kwishishini lezemigodi, umthambo, indwangu, ukuveliswa koomatshini kunye namanye amashishini ukukhuthaza ukwanda ngokukhawuleza kwenani kunye nomgangatho wevalve yobhedu, ngoko ivalve yobhedu yesilayidi.Kwakhona wasungula isilawuli sokuqala ukulungelelanisa isantya, emva koko, ulawulo lokuhamba kwamanzi ngakumbi nangakumbi.Kwaye inikwe ivalve yobhedu enesiqu esinemisonto kunye netrapezoidal enentambo yesikhondo sevalve yobhedu, uphuhliso lwevalve yobhedu yeyona nto iphambili.Ezi ntlobo zimbini ze-valve zobhedu azibonisi kuphela ukwaneliseka ngamashishini ahlukeneyo kuxinzelelo lwe-valve yobhedu kunye neemfuno zokushisa, kodwa kunye nokwaneliseka kokuqala kweemfuno zokulawula ukuhamba.

Ivalve yokuqala yobhedu kwimbali kufuneka ibe yivalve yobhedu yebhola okanye iplagi yobhedu engqukuva, eqala ngenkulungwane ye-19 kaJohn.Wallen noJohn.Charpmen, kodwa ayizange ifakwe kwimveliso ngelo xesha.

Iivalvu zokukhangela ubhedu

Emva kweMfazwe Yehlabathi yesiBini, uphuhliso lwevalve yobhedu lwagqitywa ngokukhuthazwa ngurhulumente, kwaye uMkhosi waManzi wase-US wayengumxhasi wokuqala wevalve yobhedu kaJames Bury kwinkwili.Ke malunga nokusetyenziswa kwendawo yevalve yobhedu, kwenziwa uthotho lophando olutsha kunye nophuhliso kunye nokuzama, itekhnoloji entsha yevalve yobhedu kunye nemfazwe ibe yinto entsha entsha.
Ngenxa yesidingo sokwakhiwa ngokutsha emva kwemfazwe kumazwe amaninzi, zombini iiplagi zobhedu eziphelelwe lixesha kunye neevalvu zobhedu zebhabhathane ziye zafumana ukusetyenziswa okutsha ngenxa yezixhobo ezahlukeneyo ezikhethekileyo, kubandakanya idatha ehlanganisiweyo, idatha egudileyo, insimbi engenasici kunye ne-cobalt-based cemented carbide, Ivalve yobhedu yebhola kunye nevalve yobhedu ye-diaphragm kufuneka iqhutywe ngokukhawuleza.Sika iivalve zethusi, i-valve yobhedu yesango kunye nezinye iindidi zobhedu ezidityanisiweyo, umgangatho wenkqubela phambili.Ukwenza ishishini lokuvelisa ivalvu yobhedu ngokuthe ngcembe libe licandelo elibalulekileyo loshishino loomatshini.

Ngeminyaka yoo-1960, uqoqosho oluphuhlileyo lwezoshishino lwaya kwimpumelelo nakuphuhliso.Iimveliso zelizwe elalisakuba yiNtshona Jamani, eJapan, eItali, eFransi, eBritani nakwamanye amazwe ayelangazelela ukufumana imarike yamazwe ngamazwe.Ukuthunyelwa kumazwe angaphandle kweeseti ezipheleleyo zoomatshini kunye nezixhobo ezikhokelele ekuthunyelweni ngaphandle kwevalve yobhedu.

Ukususela ekupheleni kweminyaka yoo-1960 ukuya ekuqaleni koo-1980, amazwe amadala angama-colonial ayezimele, elangazelela ukuphuhlisa ishishini lesizwe kunye nenani elikhulu lezixhobo ezithunyelwa kumazwe angaphandle, kubandakanywa iivalvu zobhedu;kunye nengxaki yeoyile yakhokelela ekubeni abavelisi beoyile batyale imali eninzi kushishino lweoli olukwizinga eliphezulu.Olu luhlu lwezizathu zorhwebo lwemveliso yevalvu yobhedu lwamazwe ngamazwe kunye nophuhliso lungenise ixesha lokukhula ngokukhawuleza, nokukhuthaza ngakumbi uphuhliso loshishino lwevalvu yobhedu.

Iivalvu zeradiyetha zobhedu

Ivalve yobhedu yinxalenye yolawulo lwenkqubo yothutho yombhobho, ukusuka kweyona ndlela ilula yokunqunyulwa kwevalve yobhedu ukuya kwinkqubo yolawulo entsonkothileyo kakhulu esetyenziswa kwiindidi zeevalvu zobhedu, kubandakanywa ivalve yebhola yobhedu, ivalve yesango lobhedu, ivalve yokukhangela ubhedu, ubhedu. ivelufa yegesi, ivelufa yobhedu, ivelufa yobhedu, ivalve yeradiyetha yobhedu, ivelufa yobhedu yeradiyetha yobhedu, ngokunjaloizixhobo zobhedu, kwaye nangokunjalo.Iivalvu zobhedu zingasetyenziselwa ukulawula ukuhamba kweentlobo ngeentlobo zolwelo olunjengomoya, amanzi, umphunga, imidiya edliwayo, udaka, i-oyile, isinyithi esilulwelo kunye nemithombo yeendaba ene-radioactive.

Ukuhanjiswa kwemarike yevalve yobhedu kusekwe ikakhulu kulwakhiwo lweprojekthi, abona bathengi baninzi beshishini lepetrochemical, icandelo lamandla, icandelo lesinyithi, ishishini lemichiza kunye namasebe okwakha ezidolophini, anje ngemibhobho yamanzi edolophini, ukwakhiwa kwezakhiwo, ukufudumeza ezidolophini. ;, Ishishini lamachiza, ishishini lokutya njalo njalo.Iivalvu zobhedu kushishino lokucoca amanzi ekusetyenzisweni kwemveliso yevalve yobhedu enkulu, ephantsi koxinzelelo oluphantsi, njengevalve yobhedu yebhabhathane, ivalve yobhedu yesango, jonga ivalve yobhedu.

Umthengisi osemgangathweni weeTshayinaiivalvu zebhola zobhedu,iivalvu zeradiyetha zobhedu,iivalve zesango lobhedu,iivalve zobhedu, sinikezela ngeentlobo zeevalvu zobhedu kunyeizixhobo zobhedungomgangatho othembekileyo nozinzileyo, wamkelekile ukuba ubuze nathishangyi@tzsyvalve.com
