I-vally yebhabhathane ephezulu
✧ Inkcazo
Ivalve yokusebenza kakhulu yebhabhathane luhlobo lwendawo eyenzelwe ukuba kufuneke izicelo ezifuna ukutywina okuqinisekileyo, amandla oxinzelelo oluphezulu, kunye nokuvalwa okuqinileyo. Ezi valves zihlala zisetyenziswa kumashishini anjengeoyile kunye negesi, ukuqhubela kwemichiza, ukuvelisa amandla, kunye nonyango lwamanzi, phakathi kwezinye. Zibonakaliswa ngokwamandla abo okubonelela ngolawulo olufanelekileyo kulawulo olufanelekileyo kwaye inyamezele imeko yokusebenza. Iimpawu eziphambili ze-vally ezisebenzayo zibandakanya ukunciphisa ukuvuza nokunikezela ngexinzelelo oluphezulu okanye indawo yobushushu obuphezulu.Robist Stion: IiValty ezisebenza kakhulu zebhateli zihlala zakhiwe ngezixhobo eziqinileyo, ezifana ne-altional yentsimbi okanye izabelo ze-tiotive, zokusebenza nzima. Ukusebenza kweTorque, ukuvumela ukuba ulungelelwaniso olusebenzayo kunye nokuncitshiswa kwezakhiwo ze-valve.iyilo olukhuselekileyo: Ezinye izinto zokusebenza kakuhle: Ukubonelela nge-valves ekhuselekileyo yokhuseleko emfazweni. : Ezi valve zilungele izicelo ezifuna ukubanakho ukuphathwa kweendleko eziphezulu. Isixhobo esifanelekileyo kunye nokukhetha kubalulekile ukuqinisekisa ukuba iValve ihlangabezana neemfuno zomsebenzi wesicelo esicetywayo.
✧ Iimpawu ze-Butterfly Valvely Valve
I-valvesm yokusebenza ephezulu yebhabhathane ibonisa i-polymer izihlalo zobomi ezingenamda kunye nokuchasana okuphezulu kweekhemikhali- iikhemikhali ezimbalwa - ukwenza ukuba ezi mveliso zinomtsalane kwizicelo ze-valve ze-valves. I-upsples yayo esemgangathweni yerabha okanye enye i-fluorocarbon polymers malunga noxinzelelo, ubushushu kwaye inxibe ukunganyangeki.
Uloyilo luphi
Isiqu se-varvery yokusebenza esiphezulu se-butterfly ivaliwe kwiZiko leeSpani ezimbini. I-OSTST yokuqala ivela kumgca we-valve, kwaye i-overse yesibini ivela kumgca ombindi wombhobho. Oku kubangela ukuba i-disc ichithe ngokupheleleyo kwi-disc kwiidigri ezimbalwa ezisebenzayo ukusuka esihlalweni. Jonga umnikezeli apha ngezantsi:
Uyilo lwesihlalo
Ngokubhekisele kwisihlalo, njengoko kuchaziwe ngaphambili, ivalve yerabha ivaliwe ngokukhukula kwi-rabeve yerabha. Umsebenzi webhabhathi ophezulu webhabhathi ye-G g vali yoyilo. Eli nani lingezantsi lichaza ukuba ukuhlala khona kuchaphazeleka njani kwi-3 fiyarios:
Emva kwendibano: Xa ihlanganisene phantsi koxinzelelo
Xa uhlanganisene phantsi koxinzelelo, isitulo sixhaswa yiplate yebhabhathane. Oku kuvumela ukutywinwa kwe-bubble kwinqanaba lokuphumla kwi-valve ye-valve yoxinzelelo.
Ingcinezelo ye-Axial:
Iprofayili ye-G-Indawo idala itywina elinzima njengoko iplate ihamba. Uyilo lokufakelwa lunciphisa intshukumo yesitulo esikhulu.
Uxinzelelo kwisakhiwo sokufakelwa:
Ingcinezelo ijika isihlalo phambili, senza amandla okutywina. Ukufakwa kwindawo yokugoba yenzelwe ukuvumela ukujikeleza kwesihlalo. Le yindlela ekhethiweyo yokuphakama.
Isihlalo se-butterfly vatve valve sinomsebenzi wememori. Isihlalo sibuyela kwimilo yayo yoqobo emva kokulayisha. Ukukwazi kwesihlalo sokubuyisa kuchazwa yimilinganiselo yokusetyenziswa ngokusisigxina kwesihlalo esisisigxina. Isiphoso esisigxina sithetha ukuba izinto ezibonakalayo zinenkumbulo engcono - iphantsi kwengcaciso engapheliyo xa umthwalo usetyenziswa. Ngenxa yoko, imilinganiselo yengcaciso esisigxina ithetha ukuphuculwa kwesihlalo sokuvuselela kunye netywina elide lokuphila. Oku kuthetha ukuphuculwa kokutywinwa phantsi koxinzelelo kunye nokuhamba ngebhayisikile. Isiphoso siyachaphazeleka ngamaqondo obushushu.
Ukupakisha kunye nokutsala uyilo
Inqaku lokugqibela lokuthelekisa yitywina elithintela ukuvuza kwangaphandle ngendawo ye-STEM.
Njengoko ubona apha ngezantsi, i-valve efakwe i-valves inesithsaba esilula, esingahlengahlengiswanga. Uyilo lusebenzisa i-stem bush ukuya kwi-shaft kunye ne-2 yeendebe zokutywina kweyona ndawo ukuvuza ukuvuza.
Akukho luhlengahlengiso lwenziwe kwindawo evaliweyo, ethetha ukuba ukuvuza kwenzeka, ivalve kufuneka isuswe kumgca kwaye ilungiswe okanye itshintshwe. Indawo esezantsi yeshabi ayinayo inkxaso ye-stem, ke ukuba amasuntswana afudukele kwindawo ephezulu okanye esezantsi yeshabi, i-drique inyuka inyuka, ikhokelela ekusebenzeni nzima.
I-valves yomsebenzi ophezulu ebhabhathane eziboniswe ngezantsi zenziwa ngepakethi eguqulwe ngokupheleleyo (itywina leshaft) ukuqinisekisa ubomi benkonzo ende kwaye akukho kuvuza kwangaphandle. Ukuba ukuvuza kwenzeka ekuhambeni kwexesha, ivalve ine-pack eguqule ngokupheleleyo i-gland. Jika kuphela iringi ye-nati ngexesha de ivuleke iye kuye.
Izinto eziluncedo kwivalve ephezulu yokusebenza
Ngexesha lokuvula kunye nokuvala kwenkqubo yentsimbi yentsimbi, kuba ukungqubana phakathi kwe-disc kunye nomphezulu wokutywina we-valve incinci kunelo ye-valve yesango, iphazamisa.
Ukuvulwa okanye ukuvala ukuvala kwe-valve stem mfutshane, kwaye inomsebenzi osikiweyo osikelweyo, kwaye ngenxa yokuba utshintsho lwesitulo se-valve sihambelana ne-disve ye-id, ilungele uhlengahlengiso ireyithi yokuhamba. Ke ngoko, olu hlobo lwevalve lufanelekile ukusika okanye ukumiselwa kunye nokubetha.
