Iivalvu zebhola zePVCbaye bahamba indlela ende ukususela ekuqalweni kwabo kwi-20th inkulungwane, bevela ekutshintsheni okulula / okucimayo ukuya kwizixhobo eziphucukileyo zokulawula ukuhamba.Kweli nqaku, silandelela ukuvela kweevalve zebhola zePVC kwaye sivavanya impembelelo yazo kwiinkqubo zokulawula ukuhamba.
PVC Ball Valve Origins
I-Polyvinyl chloride (PVC) yaqala ukwenziwa ekuqaleni kweminyaka yoo-1900, kwaye ukusetyenziswa kwayo kwimveliso yeevalvu zebhola kwalandela ngokukhawuleza.Iivalve zebhola ze-PVC zokuqala zazilula kwi-/off devices, eyenzelwe ukulawula ukuhamba okusisiseko kwizicelo zoxinzelelo oluphantsi.Ezi modeli zakuqala zenziwe ngentsimbi, kunye necandelo lebhola lePVC elijikelezayo ukutywina ngokuchasene nesihlalo sentsimbi.
Uphuhliso lweValve yeBhola yePVC
Njengoko ubuchwepheshe buqhubela phambili, iivalvu zebhola zePVC zaqala ukuveliswa ngamacandelo eplastiki ngokupheleleyo, ukunciphisa imfuneko yamacandelo esinyithi kunye nokwenza lula.Uyilo lwezihlalo kunye neebhola ziye zavela ukuphucula ukusebenza kokutywina kunye nokuqina.Iivalvu zebhola ze-PVC ziye zaxhaphaka ngakumbi kuluhlu lwamashishini, kubandakanywa amayeza, ukulungiswa kokutya, kunye nokulungiswa kweekhemikhali, apho ukuxhathisa ukubola kunye nococeko kwakubaluleke kakhulu.
Iimpawu zoLawulo lokuHamba oluphucukileyo
Kule minyaka ilishumi idlulileyo, iivalvu zebhola zePVC ziye zaphuhliswa ngakumbi ukuze zibandakanye iimpawu zolawulo lokuhamba.Ezi ziquka ulawulo oluguquguqukayo lwesantya, izixhobo zokulinganisa uxinzelelo, kunye nolawulo lwedijithali lwenkqubo echanekileyo yokuzenzekelayo.Ukongezwa kwezi mpawu kuye kwavula izicelo ezintsha ze-PVC iivalve zebhola, kubandakanywa kwiinkqubo ezibalulekileyo ezifana ne-biotechnology kunye nezicelo zoxinzelelo oluphezulu.
Impembelelo kwiiNkqubo zoLawulo lokuHamba
Iivalvu zebhola ze-PVC zinempembelelo enkulu kwiinkqubo zokulawula ukuhamba.Iipropati zabo ezinganyangekiyo kwi-corrosion ziye zatshintsha iivalve zetsimbi kumashishini amaninzi, ukuphucula ukuthembeka kwenkqubo kunye nokhuseleko.Ukongezelela, ukukwazi kwabo ukumelana noxinzelelo oluphezulu kunye namaqondo okushisa kuye kwavumela ukuyila kwenkqubo esebenzayo.Ukufika kolawulo olukrelekrele kuye kwaphucula ngakumbi iinkqubo zolawulo lokuhamba, okwenza kube lula ukulawula amazinga okuhamba kunye noxinzelelo.
Ukuqukumbela
Ukuvela kweevalvu zebhola ze-PVC kuguqule iinkqubo zokulawula ukuhamba, ukubonelela ngezisombululo ezithembekileyo, ezisebenzayo nezizinzileyo.Njengoko itekhnoloji iqhubela phambili, sinokulindela ukubona izinto ezintsha ezingakumbi kunye nezixhobo ezifakwe kwezi zivalo, ziphucula ngakumbi ukusebenza kwazo kunye nokwandisa usetyenziso lwazo.Ngelixa sihambe umgama omde ukusukela kwimihla yokuqala yeevalvu zebhola zePVC, indaleko isekude ukuba igqitywe, kwaye kusekho amandla amakhulu okuqhubela phambili nokuphucula.
