Ungakuqinisekisa kanjani ukusebenza kokubekwa uphawu kwama-valve avemvane?

Ezinhlelweni ezahlukahlukene zepayipi ezimboni, ama-butterfly ama-valves asetshenziswa kabanzi ku-fluid control scarios ngenxa yesakhiwo sabo esihlangene, ukuvulwa okusheshayo nokuvala, kanye nokusebenza okulula. Ukusebenza kokubekwa uphawu, omunye wemisebenzi emikhulu yama-valves we-butterfly, ahlobene ngokuqondile nokusebenza kokusebenza, ukuphepha nokuqina kohlelo lwepayipi. Ukubekwa uphawu okuhle akunakuvimbela ukuvuza okuphakathi kuphela, kepha futhi kwandise impilo ye-valve futhi kunciphise izindleko zokulungisa. Ngakho-ke, kanjani ukuqinisekisa ukusebenza kokubekwa uphawu kwama-valve avemvane? Lokhu kudinga ukulawulwa okuphelele kokuxhumeka okuningi okufana nokuklanywa, ukukhetha okubonakalayo, ukucubungula, ukufakwa nokulungiswa.

1. Idizayini yokwakheka iyisisekelo sokusebenza uphawu

Kunezindlela ezimbili ezinkulu zokubophaama-ama-ama-butterfly valves, enye indawo ethambile yokubopha uphawu kanti enye yisakhiwo se-sealing sensimbi. Ama-valves we-butterfly athambile avame ukusebenzisa izinto eziphakeme ezifana ne-rubber ne-polytetrafluoroethylene, enomphumela omuhle wokubekwa uphawu, efanelekile endaweni yokushisa evamile yokushisa nemvelo. Ama-balveling balleing batterfly ama-valves alungele izinga lokushisa eliphakeme, ingcindezi ephezulu noma abezindaba ezilimazayo, kepha abe nezidingo eziphakeme zokucubungula ukunemba nokusebenza okubonakalayo.

Ekwakhiweni okuhlelekile, ubuhlobo bokubhala uphawu lokufanisa kwama-butterfly valves lubalulekile. Ukulingana phakathi kwezindawo zokubopha uphawu, i-angle yokuxhumana, kanye nokusatshalaliswa kuzothinta umphumela wokubekwa uphawu. Ngakho-ke, ekuqaleni kokuklama, kuyadingeka ukuthi ucabangele ngokugcwele izici ezifana nezimpawu ze-medium, ukucindezela, izinguquko zokushisa, njll., Ukuze ukhethe isakhiwo esifanelekile sokubekwa uphawu kanye nenhlanganisela yezinto ezibonakalayo.

2. Izinto ezisezingeni eliphakeme ziyisihluthulelo sokuthola ukubekwa uphawu okuthembekile

Ukukhethwa kwezinto ezibonakalayo kungenye indlela eyisisekelo yokuqinisekisa ukusebenza uphawu. Kuma-valves we-butterfly avalwe ngokuvalwa okuthambile, izindandatho zokubopha uphawu zivame ukwenziwa ngerabha, i-EPDM, i-NBR, i-PTFE nezinye izinto. Lezi zinto zokwenziwa zinobuhlakani obuhle nokuphikiswa kokugqwala, futhi bangagcina ukuqina okuhle kanye nesimo sokubopha uphawu ngesikhathi sokuvula nokuvala isikhathi eside.

Okwenziwe ngensimbiama-ama-ama-butterfly valves, izinto zensimbi ezinamandla aphezulu njengensimbi engenasici kanye ne-carbide efakwe ngocingo ziyadingeka. Lezi zinto zokwenziwa azigcini nje ngokumelana nokushisa okuphezulu nengcindezi, kepha futhi zinokuvimbela okuqinile. Ikakhulu uma udlulisela imithombo yezindaba eqinile kakhulu noma izinhlayiya eziqinile, izakhiwo zensimbi zensimbi zikwazi ukwedlula izimo ezinzima zokusebenza.

Kuyaqapheleka ukuthi ukukhethwa kwezinto zokubopha uphawu kufanele kuhambisane nezimo ezithile zokusebenza. Ukumelana nezinga lokushisa, ukumelana nokuguga, ukumelana nokugqwala, njll. Kwezinto ezibonakalayo kudingeka zihlolwe ngokuphelele futhi azikwazi ukujwayela.

I-3. Ubuchwepheshe bokucubungula buthinta ukunemba okufanele kwendawo yokubopha uphawu

Noma ukwakheka kunengqondo futhi izinto zokwakha zisezingeni eliphakeme, ukusebenza kahle kokubekwa uphawu akunakutholwa uma ukunemba okusebenzayo kungabi kuzinga. Indawo yokubopha uphawu le-valve yevemvane idinga ukucubungulwa ngokunembile futhi inhlabathi ukuze kuqinisekiswe ukushelela kwayo nokucabangela kwayo. Ekukhiqizweni kwangempela, imihuzuko emincane, ama-burrs noma ukuphambuka ebusweni bokubekwa uphawu kungaba yingozi efihlekile yokuvuza.

Ikakhulu ama-vetterfly ama-batterfly ama-butterfly avaliwe, izidingo zobuchwepheshe zokucubungula ziqinile. Indandatho yokubopha uphawu kanye nesihlalo se-valve kumele kufaniswe nokunemba okuphezulu ukuze kuqinisekiswe uphawu oluqinile noluqinile. Ngaphezu kwalokho, ukulungiswa kwamaqembu ngesikhathi senqubo yomhlangano nakho kubalulekile kakhulu ukuqinisekisa ukuthi i-valve disc ihlala isesimweni esifanele lapho kuvulwa khona ukubekwa uphawu lapho kuvulwa khona.

I-4. Ukufakwa okulungile kuqinisekisa ukuthi isakhiwo se-BATION

Ukusebenza kokubekwa uphawu kwe-valve yevemvane akuveli kuphela kumkhiqizo uqobo, kepha futhi kuhlobene kakhulu nekhwalithi yokufaka esizeni. Ngesikhathi senqubo yokufaka, kuyadingeka ukuqinisekisa ukuthi ama-flanges epayipi kanye ne-valve ayisicaba futhi ama-bolts acindezelwe ngokulinganayo. Uma ukufakwa kungasendaweni, indandatho yokubopha uphawu ingahle icindezelwe ngokungalingani noma ngokwengxenye, ngaleyo ndlela ichithe isakhiwo sokuqala sokubekwa uphawu.

Lapho ufaka i-valve evikelekile ethambile, opharetha kufanele anake ngokukhethekile ukuthi isikhundla sendandatho yokubopha sifakwe ngokuphelele emzimbeni we-valve kanye ne-valve disc. Lapho ufaka i-valve ye-wetal-livalwe ngensimbi, kufanele kuqinisekiswe ukuthi alikho igebe noma ukuphambuka ku-valve lapho kuvaliwe. Ukuhlolwa kwengcindezi ngemuva kokufakwa kuyindlela ebalulekile yokuqinisekisa ukusebenza kokubekwa uphawu.

I-5. Isondlo ejwayelekile ukuvikela ukuguga nokugqoka

Akunandaba ukuthi muhle kanjaniI-I-butterfly valve, idinga ukulungiswa njalo kanye nokuhlolwa. Njengoba isikhathi sihamba kanye nezindawo eziphakathi, izinto ezithambile zokubopha zingase zikhule, ziqhekeze, njll., Ukuthinta umphumela wokufaka uphawu. Ngalesi sikhathi, indandatho yokubopha uphawu kufanele ithathelwe indawo ngesikhathi sokugwema ukuvuza kohlelo noma ukwehluleka okubangelwa izinkinga ezincane.

Yize i-valve yensimbi enamakamelo ihlala isikhathi eside, ingahle futhi igqoke ngemuva kokuhlinzwa isikhathi eside. Ikakhulu ngaphansi kokuvula okuvame kakhulu nokuvalwa noma izinhlayiya eziqinile eziphakathi nendawo, indawo ebekelwe uphawu ithambekele ekulimaleni okuncane. Ngokuhlola njalo ukuphela kwendawo yokubopha uphawu futhi ukugaya kahle, impilo yenkonzo yeVitterfly valve inganwetshwa futhi ukusebenza kokubekwa uphawu kungagcinwa.

Ukusebenza kokubekwa uphawu kweI-I-butterfly valveIsiqinisekiso esiyinhloko sokusebenza kwaso ezinzile ngaphansi kwezimo ezinzima zokusebenza. Ukusuka ekuklameni okuhlelekile, ukukhetha kwemishini, ukucaciswa kwemishini, ukufakwa, ukuthumela kanye nokulungiswa kwakamuva, zonke izixhumanisi zinomthelela oqondile emphumeleni wokubekwa uphawu. Lapho uthenga futhi usebenzisa imikhiqizo ye-Butterfly valve, amabhizinisi akufanele anake kuphela ikhwalithi yomkhiqizo uqobo, kepha futhi anake ukuphathwa okujwayelekile kanye nokunakekelwa ngesikhathi sokusetshenziswa.

Ngokukhethwa kwesayensi, ukusebenza okujwayelekile kanye nokuphathwa okuqhubekayo, ama-butterfly ama-valves awakwazi ukufezekisa kuphela ukulawulwa koketshezi, kepha futhi ahlinzeke neziqinisekiso eziqinile zokusebenza okuphephile nokuzinzile kwalo lonke uhlelo. Lokhu kuyisihluthulelo sokuphishekela ikhwalithi nokwethenjwa kuyo yonke iphrojekthi yobunjiniyela.
