Ama-valve okulinganisa insimbiidlala indima ebalulekile ezimbonini ezihlukahlukene ezidinga ukulawulwa okunembile kokugeleza koketshezi. Lawa ma-valve aklanyelwe ukulawula ukugeleza koketshezi noma amagesi ohlelweni, okuvumela opharetha ukuthi bagcine izilinganiso ezinembile futhi bazuze ukusebenza okuphelele. Phakathi kwezinhlobo ezahlukene ezitholakalayo, ama-valve emitha ensimbi engagqwali aya ngokuya ethandwa ngenxa yokuqina kwawo okuphakeme nokumelana nokugqwala.
Ama-valve emitha ensimbi engagqwali akhiqizwa ngokukhethekile ngezinto zensimbi engagqwali yekhwalithi ephezulu, ngokuvamile ebangeni lama-316 noma lama-304. Leli banga lensimbi engagqwali lithandwa ngenxa yokumelana kwalo namakhemikhali okuhle kakhulu, okulenza lifanelekele ukusetshenziswa ezindaweni ezinokhahlo nezifunayo. Lawa ma-valve afaneleka ngokukhethekile ukusetshenziswa embonini kawoyela negesi, ukucubungula amakhemikhali, imithi, ukudla neziphuzo, njll.
Enye yezinzuzo eziyinhloko zama-valve emitha yensimbi engagqwali ukumelana nokugqwala kwawo okuhle kakhulu. Ukugqwala kungabangela izakhi zangaphakathi ukuthi ziwohloke, okuholela ekuvuzeni nasezingcupheni zokuphepha ezingaba khona. Amavalvu ensimbi engagqwali akwazi ukumelana nokuchayeka oketshezini olubolayo noma amagesi, aqinisekise ukusebenza okuhlala isikhathi eside, okuthembekile. Lokhu kumelana nokugqwala kuvumela futhi lawa ma-valve ukuthi aphathe inhlobonhlobo yezinhlelo zokusebenza, okuwenza aguquguquke kakhulu ezindaweni ezahlukahlukene zezimboni.
Ngaphezu kokumelana nokugqwala, ama-valve emitha ensimbi engagqwali ayaziwa nangokucindezela kwawo okuhle kakhulu nokusebenza kwawo kwezinga lokushisa. Bangasebenza ngaphansi kwezingcindezi eziphezulu kanye namazinga okushisa aphezulu ngaphandle kokuphazamisa ukusebenza noma ukuphepha. Lokhu kuzenza zilungele ukusetshenziswa ezinhlelweni ezibucayi lapho ukunemba, ukunemba nokuqina kubalulekile.
Ngaphezu kwalezi zici eziphawulekayo, ama-valve emitha yensimbi engagqwali kulula ukuwafaka, ukuwagcina nokuhlanza. Ukwakhiwa kwazo okuqinile kanye nomklamo olula kwenza ukufakwa kwazo kube uhlelo olulula. Ngaphezu kwalokho, indawo yayo ebushelelezi kanye nezikhala ezincane zangaphakathi ezifile zenza kube lula ukuhlanza nokulungisa imisebenzi, ukunciphisa isikhathi sokuphumula nokuqinisekisa ukusebenza okuqhubekayo.
Kafushane, ama-valve emitha ensimbi engagqwali ayingxenye ebalulekile ezinhlelweni zezinsimbi ezidinga ukulawulwa okunembile kokugeleza koketshezi. Ukumelana nokugqwala kwazo, amandla okucindezela kanye nezinga lokushisa, ukulawulwa kokugeleza okunembile, kanye nokufaka kalula nokunakekela kubenza babaluleke kakhulu ezimbonini ezihlukahlukene. Kungakhathaliseki ukuthi asetshenziswa ezimbonini zikawoyela negesi, izikhungo zokucubungula amakhemikhali, noma imigqa yokukhiqiza ukudla neziphuzo, amavalvu emitha ensimbi engagqwali ahlinzeka ngokusebenza okuthembekile, okuphumelelayo futhi anikele empumelelweni iyonke yalezi zimboni.
Ukuze uthole imininingwane eyengeziwe yoku-oda, sicela ubheke okukhethiweamakhathalogikuIwebhusayithi esemthethweni ye-Hikelok. Uma unanoma yimiphi imibuzo yokukhetha, sicela uxhumane nabasebenzi abathengisa ku-inthanethi be-Hikelok bamahora angu-24.
