Emhlabeni wamavalvu ezimboni, amavalvu ovemvane ahlezi ngensimbi agqama njengenketho ethembekile, ephumelelayo yokulawula ukuhamba kwezinto ezihlukahlukene.Lolu hlobo lwevalvu luklanyelwe ukumelana namazinga okushisa aphezulu, izinto ezonakalisayo, kanye nemidiya ehuquzelayo, okulwenza lukhetheke kakhulu ezimbonini ezifana nowoyela negesi, ukucubungula amakhemikhali, kanye nokuphehla amandla.Kule bhulogi sizohlola izinzuzo zokusebenzisa i-valve butterfly ehlezi ngensimbi nokuthi kungani kuyisinqumo sokuqala sezinhlelo zokusebenza eziningi.

1. Ukuqina nokuphila isikhathi eside
Enye yezinzuzo eziyinhloko zamavalve evemvane ahlezi ensimbi ukuqina kwawo nokuphila isikhathi eside.Ngokungafani nama-valve anezihlalo ezithambile, ajwayele ukugqokwa lapho ebhekene nezinga lokushisa eliphezulu nezinto ezihuquzelayo, amavalvu ezihlalo zensimbi aklanyelwe ukumelana nezimo zokusebenza ezinzima.Izihlalo zensimbi zinikeza uphawu oluqinile futhi zimelana nokugqwala, ziqinisekisa impilo ende yesevisi kanye nezidingo ezincishisiwe zokulungisa.Lokhu kwenza ama-valve ovemvane ahlezi ensimbi abe yisixazululo esingabizi kakhulu sezimboni ezidinga ukusebenza kwamavalvu okuthembekile nokuhlala isikhathi eside.

2. Ukushisa okuphezulu kwezicelo
Amavalvu ovemvane ahlezi ensimbi alungele ukusetshenziswa kwezinga lokushisa eliphezulu lapho amavalvu ahlezi athambile angase ahluleke.Izihlalo zamavalvu ensimbi zingamelana namazinga okushisa adlulele ngaphandle kokuphazamisa amandla azo okuvala, zizenze zilungele izinqubo ezihlanganisa amagesi ashisayo, umusi nezinto ezincibilikisiwe.Leli khono lokusingatha amazinga okushisa aphezulu lenza ama-valve evemvane ahlezi ngensimbi abe yimpahla ebalulekile ezimbonini ezifana nokukhiqiza amandla, amakhemikhali e-petrochemicals kanye ne-metallurgy, lapho ukumelana nokushisa kuyisidingo esibalulekile.

3. Ukumelana nokugqwala
Ezimbonini lapho izinto ezonakalisayo zikhona, njengokucubungula amakhemikhali nokwelashwa kwamanzi angcolile, ukumelana nokugqwala kuyisici esibalulekile ekukhetheni ama-valve.Amavalvu ovemvane ahlala ngensimbi enziwe ngezinto ezifana nensimbi engagqwali, insimbi eyi-duplex namanye ama-alloys amelana nokugqwala futhi afanele ukuphatha amakhemikhali agqwalayo nezisombululo ezine-asidi.Izihlalo zensimbi zinikeza umgoqo ovikelayo ekugqwaleni, oqinisekisa ubuqotho be-valve nokuvimbela ukuvuza noma ukwehluleka ezindaweni ezigqwalile.

4. Ukumelana nokugqoka
Kuzinhlelo zokusebenza ezibandakanya imidiya elimazayo, efana nezimayini, i-pulp nephepha, nokubamba okunodaka, ikhono lokumelana nokuguga nokuguguleka libalulekile.Amavalvu ovemvane ahlala ngensimbi aklanyelwe ukumelana nokuguga nokugcina ukusebenza kwawo kokuvala ngisho nalapho echayeke ezinhlayiyeni ezihuqayo nokugeleza kwesivinini esikhulu.Lokhu kubenza babe ukukhetha okuthembekile kokulawula ukugeleza kwama-slurries abrasive, izimpushana nezinto eziwumbudumbudu lapho ama-valve ezihlalo ezithambile angakwazi ukuwohloka ngokushesha futhi ahluleke.

5. Ukuvala shaqa okuqinile nokulawula ukugeleza
Ama-valve uvemvane ahlezi ensimbi ayaziwa ngamakhono awo amahle kakhulu wokuvala kanye nokulawula ukugeleza okunembayo.Isihlalo sensimbi sinikeza uphawu oluqinile ngokumelene ne-disc, ukunciphisa ukuvuza nokuqinisekisa ukuhlukaniswa okuthembekile koketshezi lwenqubo.Ngaphezu kwalokho, ama-butterfly valves aklanyelwe ukulawula ngokuphumelelayo ukugeleza, okuwenza afanelekele izinhlelo zokusebenza ze-throttling ezidinga ukulawula okunembile kokugeleza.Le nhlanganisela yokuvala okuqinile kanye nokulawula ukugeleza kwenza amavalvu ovemvane ensimbi abe yinketho eguquguqukayo yezinqubo ezihlukahlukene zezimboni.

Sekukonke, izinzuzo zokusebenzisa izivalo ze-butterfly ezihlezi ngensimbi zenza kube yisinqumo sokuqala ezimbonini ezidinga izixazululo ezinokwethenjelwa, ezihlala njalo nezisebenza kakhulu.Kusukela ekumelaneni nezinga lokushisa eliphezulu nezinto ezonakalisayo kuya ekunikezeni ukuvala okuqinile nokulawula ukugeleza okunembayo, amavalvu ovemvane ahlezi ngensimbi anikeza uhla lwezinzuzo eziwenza abe ingxenye ebalulekile ezinhlelweni eziningi zezimboni.Njengoba ubuchwepheshe nezinto zokwakha ziqhubeka nokuthuthuka, ukusebenza kwamavalvu ovemvane ahlezi ngensimbi kulindeleke ukuthi kuthuthuke, kuqinise isikhundla sawo njengomdlali obalulekile emkhakheni wamavalvu embonini.
