Ama-opharetha kufanele ahlole njalo ukuvaleka, ukuguga noma ukulimala okudalwe ukungcola. Ngaphezu kwalokho, uhlelo kufanele lugezwe njalo ukuze kukhishwe ukungcola, ukugqwala nokunye ukungcola. Emapayipini aphethe uketshezi oluqukethe izinto eziqinile ezimisiwe, ukufaka izikrini noma izihlungi enhla nomfula kungasiza ekuthwebuleni imfucumfucu ngaphambi kokuthi ifinyelele kuvalvu.
* Ukukhetha impahla
Ukusebenzisa izinto ezimelana nokugqwala njengensimbi engagqwali noma ama-alloys agqinsiwe akhethekile kunganciphisa ukukhiqizwa kwezinhlayiya zangaphakathi. Lezi zinsiza futhi zimelana kangcono noketshezi olunamanzi, ukuvimbela ukuguguleka nokunqwabelana kwemfucumfucu okulandelayo.
* Izindlela zokufaka ezifanele
Ukuhlola ipayipi ukungcola kanye nemfucumfucu ngaphambi kokufaka i-valve kuvimbela ukungcola ekungeneni ohlelweni. Ukuqondanisa kahle i-valve nokuyivikela ngokuvikelekile kunciphisa izikhala lapho udoti ungahlala khona.
3. Isifinyezo
Ukwehluleka kwamavalvu e-Butterfly kanye nezixazululo zabo kuvame ukuvela ezinkingeni ezinjengokuvuza, ukuguga, ukugqwala nokufakwa okungafanele. Izinyathelo ezisebenzayo ziqinisekisa ukusebenza kahle futhi zinciphisa iziphazamiso. Ukugcinwa okuvamile, ukufakwa okufanele nokukhethwa kwezinto ezihambisanayo kubalulekile ukuze kunwetshwe impilo ye-valve. Ukubonisana nomhlinzeki wevalve uvemvane ochwepheshe nokulandela imiyalelo kungathuthukisa ukwethembeka futhi kunciphise isikhathi sokuphumula.
