Ama-valve ebholaesetshenziswa kumapayipi egesi yemvelo yizici ezibalulekile zokuqinisekisa ukuthuthwa kwegesi yemvelo ngokuphephile nangempumelelo. Phakathi kwezinhlobo ezahlukene zama-valve ebhola, ama-valve ebhola e-trunnion yiwona asetshenziswa kakhulu ezinhlelweni ezinjalo. Ukuqonda izimiso zokuklama kwamavalvu ebhola legesi yemvelo, ikakhulukazi amavalvu ebhola e-trunnion, kubalulekile konjiniyela nabasebenza embonini yamandla.
Isakhiwo kanye nomsebenzi
I-valve ye-axis yebhola egxilile iqukethe inyindilingai-valve disc (noma ibhola)ezungeza i-eksisi engaguquki ukuze ilawule ukugeleza kwegesi yemvelo. I-valve iklanyelwe ukuvumela noma ukuvimbela ukugeleza kwegesi kuye ngokuthi ibhola likuphi. Uma imbobo yebhola ihambisana nepayipi, igesi ingageleza ngokukhululeka; lapho ibhola lijikeleziswa ngamadigri angu-90, ukugeleza kwegesi kuvinjiwe. Le ndlela elula kodwa ephumelelayo inikeza indlela ethembekile yokulawula ukuhamba kwegesi yamapayipi.
I-Valve Seat Design
Isihlalo se-valve siyingxenye ebalulekile ye-valve yebhola njengoba inikeza indawo yokuvala ukuvimbela ukuvuza lapho i-valve ivaliwe. Ekusetshenzisweni kwegesi yemvelo, ngokuvamile kunemiklamo emibili eyinhloko yezihlalo zamavalvu: izihlalo eziqinile nezihlalo zensimbi.
1. Izihlalo eziqinile: Lezi zihlalo zenziwe ngezinto eziguquguqukayo njengerabha noma ama-polymer. Bahlinzeka ngezakhiwo ezinhle kakhulu zokuvala, ikakhulukazi izicelo zokucindezela okuphansi. I-elasticity yento eyivumela ukuthi ihambisane nobuso bebhola, yenze uphawu oluqinile olunciphisa ingozi yokuvuza kwegesi. Kodwa-ke, izihlalo eziqinile zingase zingasebenzi kahle emazingeni okushisa aphezulu noma ezindaweni zamakhemikhali ezinokhahlo, futhi ukusebenza kwazo kungase kwehle ngokuhamba kwesikhathi.
2. Izihlalo Zensimbi: Izihlalo zensimbi zenziwe ngezinsimbi eziqinile, njengensimbi engagqwali noma amanye ama-alloys. Lezi zihlalo zilungele izinhlelo zokusebenza ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu ngoba zingakwazi ukumelana nezimo ezibucayi ngaphandle kokuphazamisa ubuqotho bazo. Amavalvu ebhola ahlezi ngensimbi akulula ukuguga futhi afanele ukusetshenziswa isikhathi eside kumapayipi egesi yemvelo. Kodwa-ke, kungenzeka banganikezeli ngokusebenza kokuvala okufanayo njengezihlalo eziqinile, ikakhulukazi ezingcindezini eziphansi.
Ukucatshangelwa kokuklama
Lapho uklama i-valve yebhola yegesi yemvelo, izici eziningi kufanele zicatshangelwe ukuze kuqinisekiswe ukusebenza kahle. Lezi zici zihlanganisa ingcindezi yokusebenza kanye nezinga lokushisa, uhlobo lwegesi yemvelo ethuthwayo, kanye nezidingo ezithile zohlelo lwamapayipi. Onjiniyela kufanele futhi bacabangele amandla okugqwala nokuguguleka, okungaba nomthelela empilweni nokuthembeka kwevalvu.
Ngaphezu kwalokho, ukukhetha kwe-elastomer noma ukwakhiwa kwesihlalo sensimbi kuncike kuhlelo lokusebenza oluthile. Isibonelo, uma ipayipi lisebenza ngaphansi kwezingcindezi namazinga okushisa aguquguqukayo, i-valve yesihlalo sensimbi ingase ifaneleke kakhulu. Ngokuphambene, izinhlelo zokusebenza lapho ukuqina kubaluleke kakhulu futhi izimo zokusebenza zizinzile, isihlalo se-elastomer singase sibe ukukhetha okungcono.
Izimiso zokuklama zemveloama-valve ebhola legesi, ikakhulukazi ama-valve amabhola e-trunnion, abalulekile ekulethweni kwegesi yemvelo ephephile futhi ephumelelayo. Njengoba kunezinhlobo ezimbili eziyinhloko zemiklamo yesihlalo se-valve: eqinile nensimbi, onjiniyela kufanele bahlole ngokucophelela izidingo ezithile zesicelo sabo ukuze bakhethe isisombululo esifanele kakhulu. Ngokuqonda imisebenzi nokucatshangelwa komklamo walawa ma-valve, abaqhubi bangaqinisekisa ubuqotho bamapayipi egesi yemvelo futhi babe negalelo ekuphepheni kukonke kwemboni yamandla.
