I-valve yebhola iyingxenye eyinhloko kunoma iyiphi isistimu yamapayipi, inikeza indlela elula nephumelelayo yokulawula ukugeleza koketshezi namagesi.Phakathi kwezinhlobo ezahlukene zama-valve ebhola atholakalayo, ama-valve amabhola amabili ayisinqumo esithandwayo ngenxa yokuguquguquka kwawo nokuthembeka.Kulesi sihloko, sizohlola ukusetshenziswa kwama-valve ebhola, ukuthi ungasebenzisa nini i-valve yebhola eneziqephu ezimbili, kanye nezinzuzo zokukhetha inketho yekhwalithi ephezulu kumnikezeli we-valve webhola ohlonishwayo.
Iyini inhloso ye-valve yebhola?
Inhloso eyinhloko yama-valve ebhola ukulawula ukugeleza koketshezi emapayipini.Iqukethe i-spherical disk (noma ibhola) enembobo phakathi nendawo, engaphendulwa ukuze ivumele noma ivimbele ukuhamba kwemidiya.Lapho i-i-valve yebholaisendaweni evulekile, imbobo ihambisana nepayipi, ivumela abezindaba ukuba badlule.Uma isendaweni evaliwe, umgodi u-perpendicular kumbhobho, ukuvimbela ukugeleza.
Ama-valve ebhola avame ukusetshenziswa ezimbonini ezihlukahlukene, okuhlanganisa uwoyela negesi, amakhemikhali e-petrochemicals, ukuhlanza amanzi namanzi angcolile, ukukhiqiza amandla, nokunye.Zithandwa ngenxa yekhono lazo lokuvala ngokushesha nangokuthembekile, kanye nekhono lazo lokumelana nezingcindezi eziphezulu namazinga okushisa.
Kufanele ngisebenzise nini i-valve yebhola eneziqephu ezimbili?
A i-valve yebhola eneziqephu ezimbilikuwuhlobo olukhethekile lwe-valve yebhola equkethe izingxenye ezimbili ezihlukene, umzimba kanye nesiphetho sokugcina.Lo mklamo kulula ukuwugcina nokuwulungisa njengoba i-valve ingahlakazwa ngaphandle kokuyikhipha epayipini.Ilungele izinhlelo zokusebenza ezidinga ukunakekelwa okujwayelekile noma ukuhlolwa, namasistimu angase adinge ukushintshwa noma ukuthuthukiswa ngokuzayo.
Ivalvu yebhola egxilile enezicucu ezimbili ekhiqizwa yi-CEPAI isetshenziswa kakhulu ukusika noma ukuxhuma okuphakathi epayipini.Ingasetshenziswa emanzini, umusi, uwoyela, igesi ewuketshezi, igesi yemvelo, igesi yamalahle, i-nitric acid, urea neminye imithombo yezindaba.Lokhu kukwenza kube ukukhetha okuguquguqukayo kwezinhlelo zokusebenza ezihlukene zezimboni ezingase zidinge ukulawula izinhlobo ezahlukene zemidiya.Ukwengeza, umklamo we-trunnion uqinisekisa ukuzinza okukhulu nokusekelwa kwebhola, okuvumela izingcindezi eziphakeme namasayizi amakhulu.
Ukukhetha umphakeli we-valve ofanele kubalulekile ekuqinisekiseni ikhwalithi nokusebenza kwe-valve.Abahlinzeki abahlonishwayo njenge-CEPAI banikeza izinhlobonhlobo zezinketho ukuze ivumelane nezidingo ezahlukene futhi imikhiqizo yabo yenziwa ngokwezindinganiso zamazwe ngamazwe ukuqinisekisa ukwethembeka nokuqina.
Sengiphetha, ama-valve ebhola adlala indima ebalulekile ekulawuleni ukugeleza koketshezi emapayipini, futhi ama-valve aneziqephu ezimbili zebhola ayindlela eguquguqukayo nesebenzayo ezisetshenziswa eziningi.Kuyinketho edumile kuzo zonke izimboni ngenxa yokulula kwayo ukulungiswa nokukhanda kanye nekhono lokusingatha izinhlobonhlobo zama-voltage aphakathi nendawo naphezulu.Uma ukhetha i-valve ye-ball-piece-piece, kubalulekile ukucabangela izidingo ezithile zesistimu bese ukhetha umphakeli onokwethenjelwa ukuze uqinisekise izinga nokusebenza kwe-valve.
