Umgaqo oPhakathi kunye nokusetyenziswa kwePalve yesango

Kwiziko lemizi-mveliso yexesha lezomzi-mveliso,I-valves yesango, njengohlobo oluqhelekileyo lwevalve, lusetyenziswa ngokubanzi kwimimandla emininzi enjengeoyile, igesi yendalo, unyango lwamanzi, kunye nombane. Yinxalenye engenakuphikwa kwenkqubo yombhobho ngenxa yolwakhiwo olulula, ukusebenza okuthembekileyo, kunye nobuchule bokulawula obunelisayo. Eli nqaku liza kwazisa imigaqo-siseko yokusebenzela ye-valve yesango, kunye neenzuzo kunye nezilumkiso ezikwizicelo ezisebenzayo.

1. Isakhiwo esisisiseko kunye nomgaqo wokuSebenza wePoove yesango

I-valve yesango yivali elawula ukuhamba kwe-fluid ngokunyuka kweplate ye valve. Isifundo sayo esingumsebenzi: Xa ipleyiti ye-valve ikwindawo ephakanyisiweyo ephakanyisiweyo, ulwelo lombhobho lunokuhamba kakuhle; Xa iplate ye-valve ihla kwisikhundla sokutywina, ukuhamba kwamanzi kunqunyulwe ngokupheleleyo. Umphezulu wokutywina phakathi kweplate ye-valve kunye nesihlalo sevali uqinisekisa ukuba ulwelo aluyi kuvuza xa ivaliwe.

Ngokukodwa, i-valve yesango iqulathe ibhulukhwe yevali, isihlalo sevali, ipleyiti ye-valve, i-valve, isaphetha kunye nezinye izinto. Isandla okanye isixhobo sombane siqhuba ipleyiti ye-valve ukuba inyukele phezulu kwaye ijikeleze i-valve stem, ke iyakuqonda ukulawulwa kokuguqula. Ngexesha lokusebenza, ipleyiti ye-valve igqitha kwisikhululo sokuhamba kombhobho kwaye ihlala ivulekile okanye ivaliwe ngokupheleleyo, ngoko ke ivalve ifanelekile ukuba ivulekelwe ngokupheleleyo okanye ivaliwe ngokupheleleyo.

2. Inkqubo yokusebenza ye-valve yesango

Xa umsebenzisi ejikeleza i-handheel ye-valve, isiqu se-valve siqala ukujikeleza, kwaye ipleyiti ye-valve inyukela phezulu. Xa iplate ye-valu iphakama, ijelo lokuhamba ngaphakathi kombhobho livulekile ngokupheleleyo kwaye ulwelo lunokuhamba ngokukhululekileyo; Xa i-vateve ihla, inxibelelana ngokusondeleyo nesihlalo sevali ukwenza itywina elipheleleyo ukuthintela ukudlula kwe-fluid.

Kufuneka ichaze ukuba ukuvulwa nokuvulwa kwe-valve yesango kufuna i-torque enkulu, ngakumbi kwimibhobho eneedayamitha ezinkulu okanye uxinzelelo oluphezulu. Ukwenzela ukunciphisa amandla okusebenza, i-valve yesango idla ngokuxhotyiswa ngesixhobo sokuhambisa, njenge-drive yombane okanye ibhokisi yegiya.

3. IINGXAKI ZAMANQAKU AQHELEKILEYO

Ngenxa yoyilo lwayo olukhethekileyo, iI-Palve yesangoUnezibonelelo ezininzi ezingenazo ezinye iivavavu. Okokuqala, i-valve yesango inomnqweno wokuvula okukhawulezayo kunye nokuvula kunye nokuvala okuncinci, kwaye ixhathise kancinci kwiindlela zokuhamba kwamanzi xa kuvulwa, nto leyo eyenza ilungele iinkqubo zokuhamba kwemibhobho. Okwesibini, i-valve yesango idla ngokusebenzisa imigangatho yokutywinwa yensimbi, enokunxiba inqaba kunye nokunganyangeki kobushushu obuphezulu, ukuze sihlale sisenza inkonzo ende yenkonzo.

Ukongeza, i-valve yesango isebenza kakuhle kakhulu, enokuthintela ngokufanelekileyo ukuvuza kwamanzi kwaye iqinisekise ukusebenza okukhuselekileyo nokuzinzileyo kwale nkqubo. Xa ivulekile ngokupheleleyo, i-valve yesango iphantse yabakho krwada kulwelo, ukunciphisa ukulahleka kwamandla kwinkqubo.

4. Imeko yesicelo samasango

I-vilves yesango isetyenziswa ngokubanzi kumzi mveliso, ngakumbi kwiimeko apho ukuhamba okukhulu, kuvulwa ngokupheleleyo okanye ukuvalwa kokuhamba kwe-fluid kuyafuneka. Umzekelo, kwiindlela ze-oyile kunye nendalo yegesi, iinkqubo zegesi, iinkqubo zesango zihlala zisetyenziselwa ukucima i-pipeling yodluliselo ukuqinisekisa ukuthutha ngokukhuselekileyo kolwelo; Kumzi-mveliso wamandla, i-vilve yesango isetyenziselwa ukulawula imibhobho yeSteam ukunceda ukulawula ukuhanjiswa kwamandla; Kwicandelo lonyango lwamanzi, i-valve yesango isetyenziselwa ukulawula ukuhamba nokuvuza imibhobho yamanzi eyahlukeneyo.

Ngenxa yokuba ubume be-valve yesango bulula, ulondolozo kunye nokusebenza kunye nokusebenza nako kuya kube lula. Kwiimeko ezininzi, i-valve yesango kufuneka ijonge rhoqo ukunxiba iplate ye-valve, indawo yokutywina kunye ne-valve stem ukuqinisekisa ukusebenza kwayo ngokutyeqweni kwaye kukuphepha ukunxiba neengxaki zomsebenzi wexesha elide.

I-5. Izilumkiso xa usebenzisa isango lesango

Nangona i-valve yesango isebenza kakuhle, kusekho iinkalo ezininzi ekufuneka ziqwalaselwe xa bezisebenzisa. Kuqala, i-valves yesango ayifanelekanga kumgaqo wokuhambahamba ngenxa yokuba uyilo lwe-valve ye-valve ayikufaneli kwi-veli yokuhamba kwaye iqhele ukunxiba iplate ye-valve xa ivuliwe. Okwesibini, i-valve yesango ivuliwe kancinci kunye nesantya sokuvala, kwaye ukusebenza ngokukhawuleza kunokubangela ukonakala kwivali, ke ivili le-valve okanye i-valve lijikelezwe kancinci kwaye lijikelezwe rhoqo ngexesha lokusebenza.

Ukongeza, umphezulu wokutywina kwe-valve yesango ithethwe kukungasebenzi okanye ukunxiba, ke iipropathi zolwelo kunye neemfuno zomsebenzi wokusebenza kufuneka ziqwalaselwe xa ukhetha izixhobo. Umzekelo, kubushushu obuphezulu okanye iindawo ezinobushushu obuphezulu, ezifanelekileyo kubushushu obuphezulu okanye izinto ezinganyangekiyo kufuneka zikhethwe ukwandisa ubomi benkonzo ye-valve yesango.

I-valves yesangoDlala indima ebalulekileyo kwishishini lanamhlanje kunye nomgaqo wazo wokusebenza olula nefanelekileyo. Inzuzo yayo ephambili kukuba ibonelela ngolawulo oluthembekileyo oluvulekileyo okanye oluvaliweyo kwaye lilungele iinkqubo zemibhobho kunye noxinzelelo olukhulu. Ukuqonda umgaqo-nkqubo oPhakathi kunye nokhuseleko lwamasango awancedi nje ukuphucula ukusebenza kwezixhobo, kodwa kukuqinisekisa uzinzo noKhuseleko lweNkqubo kwizicelo ezisebenzayo. Ngonyulo olusebenzayo kunye nolondolozo lwenzululwazi, i-valve yesango inokubonelela ngenkxaso yexesha elide kunye nokukhusela iinkqubo zemibhobho kumashishini ahlukeneyo.

Ukuba unezidingo okanye imibuzo malunga ne-valde yesango, nceda ukhululeke ukuqhagamshelana neqela lethu lobugcisa, siya kukubonelela ngezisombululo kunye nenkxaso.
