I-Butterfly Valves iyasebenza kanjani?

I-butterfly valveUhlobo lwe-valve olusebenzisa i-disc ukuvulwa nokuvala ingxenye yokuphindisela cishe ama-90 ° ukuvula, ukuvala noma ukulungisa izinga lokugeleza kwe-medium. I-Butterfly valve ayigcini nje ngesakhiwo esilula, isisindo esincane, isisindo esikhanyayo, ukusetshenziswa okuphansi okubonakalayo, usayizi omncane wokufaka, ukusebenza okulula kokuhamba, kepha kungenye yezimpawu zokulinganisa okusheshayo, futhi kungenye yezimpawu ezikhula ngokushesha kakhulu kule minyaka eyishumi edlule. Ama-butterfly valves asetshenziswa kabanzi. Izinhlobonhlobo kanye nobungako bokusetshenziswa kwalo kuqhubeka ukwandisa, futhi kuthuthukiswe ekushiseni okuphezulu, ingcindezi ephezulu, ububanzi obukhulu, ukuqina okuphezulu, izici ezihamba phambili, kanye nemisebenzi eminingi ye-valve eyodwa. Ukwethembeka kwalo nezinye izinkomba zokusebenza kufinyelele ezingeni eliphakeme.

Ngokusebenzisa irabha lokumelana ne-cemerant amelana namakhemikhali ukuzeama-butterfly valves, ukusebenza kweama-butterfly valveskwenziwe ngcono. Ngoba irabha yokwenziwa linezici zokumelana nokugqwala, ukumelana nokuguguleka, ukuqina okulula, ukuqina okuhle, irabha elenziwayo elinezidingo ezahlukahlukene zokusebenzisa izidingo ezihlukile zokuhlangabezana nezidingo zokusebenza zeama-butterfly valves.

Ngoba i-polytetrafluoroethylene (PTFE) inokumelana okuqinile kokugqwala, ukusebenza okuzinzile, akulula ukukhuphuka kwezingxabano, okulula ukukwenza, kanye nemikhawulo yensimbi yokwenziwa inqotshwa, ngakho-ke ukulinganiselwa kwe-polymeric yokwenziwa Izinto ezimelwe yi-PTFE kanye nokugcwaliswa kwayo okuguquliwe kusetshenziswe kabanzi ku-valve yakwaButterfly, ukuze ukusebenza kwe-valve yevemvane kuthuthukisiwe.Ama-butterfly valvesNgobubanzi obubanzi bokushisa kanye nezingcindezi, ukusebenza okuthembekile kokubekwa uphawu kanye nempilo yenkonzo ende yenziwe.

Ukuze uhlangabezane nezidingo zezicelo zezimboni ezinjengamazinga okushisa aphezulu futhi aphansi, ukuguguleka okuqinile, kanye nempilo ende, ama-valve we-butterfly wensimbi athuthukiswe kakhulu. Ngokusebenzisa ukumelana okushisa okuphezulu, ukumelana okushisa okuphansi, ukumelana okuqinile kokugqwala, ukumelana nokuguguleka okuqinile, kanye nezinto eziphakeme ze-alley ezisetshenziswayo, kanye nama-valves aphansi, kanye ne-valves ende, kanye ne-butterfly (-196 ~ 606 ° C) Uvele, ukuze ubuchwepheshe bama-valves butterfly bufinyelele ezingeni elisha.

Lapho kuvulwa i-butterfly valve ngokuphelele, inokuphikiswa okuncane. Lapho ukuvulwa kuphakathi kuka-15 ° ~ 70 ~ 70 ~ 70 ~ 70 ~ 70 ~ 70 °, ngakho-ke ukusetshenziswa kwe-Butterfly Valve kuvame kakhulu emkhakheni wokulungiswa kobubanzi obukhulu.

Ngenxa yokuhamba okusukayo kwepuleti levemvane levemvane, iningi lama-butterfly ama-valves angasetshenziselwa abezindaba ngama-solids amisiwe. Ngokuya ngamandla we-seal, kungasetshenziselwa nemidiya eyimpuphu ne-granular.

Ama-butterfly valves alungele umthetho wokugeleza. Ngoba ukulahleka kwengcindezi kwe-valve yale vevefly embhodlweni kukhulu, cishe isikhathi sikathathu leso se-valve yesango, ithonya lokuphelelwa kwengcindezi kohlelo lwepayipi kufanele lubhekwe ngokugcwele, futhi luvaliwe kufanele lubhekwe. Ngaphezu kwalokho, ukulinganiselwa kwezinga lokushisa elisebenzayo lapho izinto zokugcina ze-elastomeric zingabekwa khona emazingeni okushisa aphezulu kufanele futhi kubhekwe.

I-butterfly valve inobude obuncane bokwakha nokuphakama okuphelele, okusheshayo nokuvula nokuvala isivinini, kanye nezimpawu ezinhle zokulawula uketshezi. Isimiso sesakhiwo sama-valves we-butterfly silungele kakhulu ukwenza ama-valve amakhulu. Lapho kudingeka i-butterfly valve ukuthi isetshenziselwe ukulawula isilinganiso sokugeleza, kubalulekile ukukhetha usayizi ofanele nohlobo lwe-batterfly valve ukuze isebenze kahle nangendlela efanele.

Ngokuvamile, ekuphatheni okusheshayo, ukulawulwa komthethonqubo kanye nodaka, ubude besakhiwo bufushane, ijubane lokuvula nokuvala liyashesha, kanye nengcindezi ephansi yokugaya (umehluko omncane wengcindezelo) iyadingeka. Ama-butterfly ama-valves angasetshenziswa uma kunokulungiswa kwesikhundla ezimbili, isiteshi esincishisiwe, umsindo ophansi, i-cavitation kanye ne-vaporization, inani elincane lokuvuza emkhathini, kanye nabezindaba abanolaka. Ngaphansi kwezimo zokusebenza ezikhethekile, ukunciphisa ukulungiswa, noma ukubekwa uphawu okuqinile, ukugqoka okukhulu, izinga lokushisa eliphansi (i-crygenic) nezinye izimo zokusebenza.
