Emkhakheni wobunjiniyela bezimboni, ama-valve ebhola ayizingxenye ezibalulekile ezidlala indima ebalulekile ekulawuleni ukugeleza koketshezi namagesi. Lawa ma-valve aziwa ngokuguquguquka kwawo, ukwethembeka, nokusebenza kahle, okuwenza abe yisinqumo esidumile ezimbonini ezahlukahlukene. Kusukela kuwoyela negesi ukuya ekwelashweni kwamanzi nasekucutshungulweni kwamakhemikhali, ama-valve ebhola abalulekile ekuqinisekiseni ukulawulwa kokugeleza okubushelelezi nokunembayo.
Yini eyenza ama-valve ebhola ahluke kwezinye izinhlobo zama-valve umklamo wawo olula kodwa ophumelelayo. I-valve yebhola iqukethe idiski eyindilinga enembobo phakathi nendawo ezungezayo ukuze ivumele noma ivimbele ukugeleza koketshezi. Lo mklamo unikeza izinzuzo ezimbalwa, okuhlanganisa ukwehla kwengcindezi encane, ukuvala uphawu okuqinile, nokusebenza ngokushesha. Ngakho-ke, ama-valve ebhola asetshenziswa kakhulu ezinhlelweni ezidinga ukuvala ngokushesha nangokunembile.
Enye yezinzuzo eziyinhloko zama-valve ebhola yikhono labo lokusingatha ukucindezela okubanzi namazinga okushisa. Kungakhathaliseki ukuthi isitimu esinengcindezi ephezulu endaweni yokuphehla amandla noma amakhemikhali abolayo endaweni yokukhiqiza, amavalvu ebhola aklanyelwe ukumelana nezimo ezibucayi ngaphandle kokuphazamisa ukusebenza. Lokhu kubenza babe ukukhetha okuthembekile kwezinqubo ezibalulekile lapho ukuphepha nokusebenza kahle kubalulekile.
Ngaphezu kokwakhiwa kwawo okuqinile, ama-valve ebhola ayaziwa nangezidingo zawo eziphansi zokugcinwa. Uma kuqhathaniswa nezinye izinhlobo zama-valve, ama-valve ebhola anezingxenye ezimbalwa ezihambayo futhi ajwayele ukuguga futhi adabuke, okuholela empilweni ende yesevisi kanye nesikhathi esincane sokuphumula. Lokhu akugcini nje ngokusindisa izindleko zemboni kodwa futhi kuqinisekisa ukusebenza okungaphazamiseki, ngaleyo ndlela kwandise umkhiqizo jikelele.
Enye inzuzo yama-valve ebhola ukuguquguquka kwawo ekusetshenzisweni. Kungakhathaliseki ukuthi okokulawula/ukuvala, ukuphonseka noma ukuphambukisa, amavalvu ebhola angenziwa ngendlela oyifisayo ukuze ahlangabezane nezidingo ezithile. Lokhu kuvumelana nezimo kubenza bafanelekele izimboni ezihlukahlukene, kusukela ezitshalweni ze-petrochemical kanye nezindawo zokuhlanza kuya ezindaweni zokukhiqiza imithi nokudla.
Ukwengeza, intuthuko yezobuchwepheshe iholele ekuthuthukisweni kwezinhlobo ezahlukene zama-valve ebhola ukuze kuhlangatshezwane nezidingo ezithile. Isibonelo, ama-valve ebhola afakwe nge-trunnion aklanyelwe izinhlelo zokusebenza ze-high pressure, kuyilapho ama-valve amabhola antantayo afaneleka ukucindezela okuphansi kanye nokusetshenziswa kwenhloso evamile. Ngaphezu kwalokho, izinto ezifana nensimbi engagqwali, ithusi ne-PVC zisetshenziselwa ukuqinisekisa ukuhambisana nemidiya ehlukene kanye nezimo zemvelo.
Ukuthuthukiswa kobuchwepheshe be-valve yebhola nakho kuholele ekuhlanganisweni kwezinhlelo ezizenzakalelayo nokulawula, kwathuthukisa ukusebenza kwazo. Ngokuhlanganisa ama-actuator nama-positioners, ama-valve ebhola angasebenza futhi aqashwe ukude, okuvumela ukulawula okunembayo kanye nempendulo yedatha yesikhathi sangempela. Leli zinga le-automation aligcini nje ngokuthuthukisa ukusebenza kahle, kodwa futhi lifaka isandla ekuphepheni kukonke nokuthobela imithetho.
Kafushane, ama-valve ebhola abe yingxenye ebaluleke kakhulu embonini yesimanje, ehlanganisa ukuguquguquka, ukusebenza nokuthembeka. Ikhono labo lokusingatha ukucindezela okubanzi namazinga okushisa, izidingo zokugcinwa okuphansi, nokuvumelana nezimo ezihlukahlukene zezinhlelo zokusebenza kubenza kube yisinqumo sokuqala sokulawula ukugeleza. Njengoba imboni iqhubeka nokuthuthuka, indima yamavalvu ebhola ekuqinisekiseni ukusebenza kahle nokuphephile isalokhu ibalulekile, iqinisa isikhundla sazo njengento ebalulekile yobunjiniyela bezimboni.
