Amavalvu we-butterfly asebenza njani?

Ivalvu ye-butterflymhlobo wevalvu esebenzisa i-disc yokuvula nokuvala ingcenye ukubuyela emuva ngama-90° ukuvula, ukuvala nofana ukulungisa izinga lokugeleza kwe-medium. Ivalvu ye-Butterfly ayinayo kwaphela isakhiwo esilula, ubukhulu obuncani, ubunzima obulula, ukusetjenziswa kwezinto ezincani, ubukhulu bokufaka obuncani, i-torque encani yokutjhayela, ukusebenza okulula nokurhabako, kodwana inomsebenzi omuhle wokulawula ukugeleza nokuvala ubujamo, begodu ingenye yemihlobo yevalvu ekhula msinyana eminyakeni elitjhumi edlulileko. Amavalvu we-butterfly asetjenziswa khulu. Ukuhlukahluka nobunengi bokusetjenziswa kwayo kuyaragela phambili nokwanda, begodu kuthuthuke ukuya emazingeni womtjhiso aphezulu, ukugandeleleka okukhulu, ububanzi obukhulu, ukuqina okuphezulu, ipilo ede, ubujamo obuhle khulu bokulawula, kanye nemisebenzi eminengi yevalvu yinye. Ukuthembeka kwayo nezinye iinkomba zokusebenza zifinyelele ezingeni eliphezulu.

Ngokusetjenziswa kwerabha yokwenziwa ejamelana namakhemikhaliamavalvu wevithamini, ukusebenza kweamavalvu wevithaminisele yenziwe ngcono. Ngombana irabha yokwenziwa ineemfanelo zokujamelana nokugqwala, ukujamelana nokuguguleka, ukuzinza kwemilinganiso, ukujamelana okuhle, ukwakheka lula, iindleko eziphasi, njll., irabha yokwenziwa eneempawu ezihlukileko ingakhethwa ngokuya ngeemfuneko ezihlukileko zokusetjenziswa ukuhlangabezana nobujamo bokusebenzaamavalvu wevithamini.

Ngombana i-polytetrafluoroethylene (PTFE) inokujamelana nokugqwala okuqinileko, ukusebenza okuzinzileko, akulula ukuguga, i-coefficient ephasi yokutjhayisana, kulula ukuyibumba, ukuzinza kwemilinganiso, begodu ingathuthukisa izakhiwo zayo ezipheleleko ngokuzalisa nokungezelela izinto ezifaneleko, izinto zokuvala i-valve ye-butterfly enamandla angcono kanye ne-coefficient ephasi yokutjhayisana, ingathola ukulinganiselwa nokulinganiselwa irabha yokwenziwa iyahlulwa, njeke into ye-polymer polymeric emelelwa yi-PTFE kanye nezinto zayo ezitjhugululiweko ezisetjenziswe khulu ku-butterfly valve, ukwenzela bona ukusebenza kwe-butterfly valve kuthuthukiswe khulu.Amavalvu we-butterflyngezinga elibanzi lamazinga womtjhiso kanye nokugandeleleka, ukusebenza okuthembekileko kokuvala kanye nokuphila isikhathi eside kwesevisi kwenziwe.

Ukuhlangabezana neemfuneko zokusetjenziswa kwebubulo ezifana namazinga womtjhiso aphezulu naphasi, ukuguguleka okunamandla, nokuphila isikhathi eside, amavalvu we-butterfly we-seal ensimbi athuthukiswe khulu. Ngokusetjenziswa kokujamelana nokutjhisa okuphezulu, ukujamelana nokutjhisa okuphasi, ukujamelana nokugqwala okunamandla, ukujamelana nokuguguleka okunamandla, kanye nezinto ezinamandla amakhulu we-alloy kumavalvu we-butterfly, ama-valve we-butterfly avaliweko wesimbi asetjenziswe khulu emasimini wamabubulo afana nokutjhisa okuphezulu nokuphasi, ukuguguleka okunamandla, nokuphila isikhathi eside, kanye namavalvu we-butterfly anobubanzi obukhulu (~750), umfutho ophakemeko (~750 MP). kanye namazinga womtjhiso abanzi (-196~606°C) avele, ukwenzela bona ithekhnoloji yamavalvu we-butterfly ifinyelele ezingeni elitjha.

Lokha ivalvu ye-butterfly nayivulwa ngokuzeleko, inokujamelana nokugeleza okuncani. Lokha ukuvuleka kuphakathi kwama-15°~70°, kungasetjenziselwa ukulawula ukugeleza okubucayi, ngalokho ukusetjenziswa kwevalvu ye-butterfly kuvame khulu emkhakheni wokulungisa ububanzi obukhulu.

Ngebanga lokunyakaza okususwako kwepuleti yevithamini ye-butterfly valve, inengi lama-butterfly valve lingasetjenziselwa imidiya enezinto eziqinileko ezilengisiweko. Ngokuya ngamandla wesivalo, singasetjenziselwa nemidiya enepuyere neye-granular.

Amavalvu we-butterfly alungele ukulawula ukugeleza. Ngombana ukulahlekelwa mfutho we-butterfly valve ngaphakathi kwepayipi kukhulu, okuphindwe kathathu kune-gate valve, lokha nakukhethwa i-butterfly valve, umthelela wokulahlekelwa mfutho wehlelo lephayiphi kufanele uqalwe ngokuzeleko, begodu namandla wepuleti le-butterfly ukuthwala umfutho wephayiphu lokha nayivaliweko kufanele kuqalwe. Ukungezelela, ukulinganiselwa kwamazinga womtjhiso wokusebenza lapho izinto zesihlalo se-elastomeric zingafakwa khona emazingeni womtjhiso aphezulu kufanele kuqalwe.

Ivalvu ye-butterfly inobude obuncani nobude obupheleleko, ukuvula nokuvala okurhabako, kanye neemfanelo ezihle zokulawula amanzi. Umthetho wokwakheka kwamavalvu we-butterfly ulungele ukwenza amavalvu amakhulu. Lokha nakutlhogeka bona kusetjenziswe i-valve ye-butterfly ukulawula izinga lokugeleza, kuqakathekile ukukhetha ubukhulu nohlobo olufaneleko lwe-butterfly valve ukwenzela bona isebenze kuhle begodu ngepumelelo.

Ngokuvamileko, ekuthomeni, ukulawula umthetho kanye nodaka, ubude besakhiwo bufitjhani, ijubane lokuvula nokuvala lirhaba, begodu ukusika kwengcindezi ephasi (umehluko omncani wengcindezi) kuyatlhogeka, begodu i-valve ye-butterfly iyaphakanyiswa. Amavalvu we-butterfly angasetjenziswa lokha nakunokulungiswa kweendawo ezimbili, umzila onciphileko, umsindo omncani, ukutjhwaba nokuvuza, ukuvuza okuncani emoyeni, kanye nemidiya yokuhlaba. Ngaphasi kweemeko ezikhethekileko zokusebenza, ukulungiswa kokugandeleleka, nofana ukuvala okuqinileko, ukuguga okukhulu, izinga lokutjhisa eliphasi (i-cryogenic) nezinye iimeko zokusebenza.
