Kungani ama-butterfly ama-valves angasebenzi kahle njalo?

Ukwehluleka njalo kweama-ama-butterfly valveszivame ukuhlobene nokwehluleka kwesilinganiso, ukusebenza okungajwayelekile, nokuphazamiseka kwangaphandle. Ukuhlaziywa okulandelayo kuzoqhutshwa ngokususelwa ezinhlotsheni ezithile zokwehluleka:

Ukwehluleka kokubekwa uphawu okuholela ekuvuza: ukulimala kwendawo yokubopha uphawu noma ukushukumisa ukungcola kuyizimbangela ezivamile. Ngemuva kokusetshenziswa kwesikhathi eside, indawo ebeka uphawu phakathi kwepuleti levemvane nesihlalo se-valve izolinyazwa yingxabano nokugqoka, noma ukungcola nokungcola okuphakathi kuzonamathela. Isibonelo, ukuguga, ukuqina, noma ukugqwala kwendandatho yokubopha kuqhume inkinga yokuvuza. Ngaphezu kwalokho, ukuvuza emaphethelweni womabili ama-valve kuvame ukubangelwa ukwehluleka kwe-bamber gasket noma ukuqinisa okuvuthayo kwepayipi, kanti ukuvuza kuvuvukala kuhlobene ngqo nokugqokwa kwezinto zokubopha.

Ukusebenza okungajwayelekile kungadala ukwehluleka okusebenzayo: i-valve ayikwazi ukuvulwa ngokuphelele noma ivalwe, imvamisa ibangelwa ukuqhekeka kwento yakwamanye amazwe (njenge-slag eqinile noma ukuhanjiswa kwamadivaysi okuhambisayo (njengamagiya e-germ kanye negiya le-gear). I-torque yokusebenza ngokweqile ingahle iholele ekusakazweni kwamandla angalingani ngenxa yokungqubuzana okuphezulu phakathi kwesiqu se-valve nokupakisha, ukungalingani phakathi kwepuleti levemvane kanye nomzimba we-valve, noma ukufakwa okungafanele. Isibonelo, isiqu se-valve egobekile noma esinamathele singavimbela ngokuqondile isenzo se-valve, ngenkathi ukuthambisa okunganele kungandisa ukugqoka kwizakhi zokuhambisa, kwakha umjikelezo omubi.

Ukuphazanyiswa kwangaphandle kungaholela ekunciphiseni kokusebenza: izinga lokugeleza ngokweqile kwe-medium lingakhiqiza ukwethuka kanye nesiphithiphithi, okubangela ukudlidliza kwe-valve nomsindo, nokusebenza isikhathi eside kungalimaza ukwakheka komzimba we-valve. I-resonance ebangelwa ukufakwa okungazinzile izothuthukisa inkinga yokudlidliza. Ngaphezu kwalokho, izici zezemvelo ezinjengomswakama ophezulu zingasheshisa ukubhujiswa kwezinto zensimbi, kuyilapho ukuguga okungajwayelekile (ukwehluleka okuphansi kokushisa okuphansi, ukwehluleka okuphansi kokufuywayo) kuthinta ngqo ukusebenza kwezinto zokwakha kanye nezakhi zokuhambisa. Isibonelo, ugesiama-ama-butterfly valvesingahle isebenze kancane ezindaweni zokushisa okuphansi ngenxa yokwanda kokubonakala kwamafutha okugcotshwa kwamafutha.
