Iivalve zesango kunyeiivalve butterflykumbhobho zisetyenziselwa ukudlala indima yokutshintsha, ukulawula ukuhamba. Ewe kunjalo, kusekho indlela ekukhetheni iivalve zebhabhathane kunye neevalvu zesango.
Iimpawu ezifanayo zexabiso levalve yesango liphezulu kunexabiso levalve yebhabhathane. Kodwa ukususela ekusebenziseni iminyaka elishumi edlulileyo, ukusilela kwevalve yebhabhathane kune-valve yesango ephezulu, ngoko ke kwiimeko zemvume, ukwandisa ukusetyenziswa kwevalve yesango kufanelekile ukuhoywa.
Ivalve yebhabhathane ekusebenziseni umahluko wevalvu yesango:
Ngokuhambelana nendima yevalve yesango kunye nokusetyenziswa kwevalve, ivalve yesango yokumelana nokuhamba kuncinci, ukusebenza kakuhle kokutywina, kuba ipleyiti yevalve yesango kunye nokuhamba kwemidiya yi-engile ethe nkqo, ukuba ivalve yesango. kwivalve iswitshi ayikho endaweni, eendaba kwipleyiti ivelufa scouring ukuze ipleyiti ivelufa ukungcangcazela, kulula kakhulu ukuba kukhanye kumonakalo ivalve yesango itywina.
Ipleyiti yebhabhathane eqhutywa sisikhondo sevalve, ukuba iguqulwe ngama-90 °, iya kukwazi ukugqiba ukuvulwa nokuvala. Guqula i-angle yokuphambuka yepleyiti yebhabhathane, unokulawula ukuhamba kwemidiya.
Ukusetyenziswa kweemeko kunye neendaba: ivalve yebhabhathane ifanelekile kwiziko, igesi, igesi yendalo, igesi yepetroleum engamanzi, igesi yesixeko, umoya oshushu nobandayo, ukunyibilikiswa kweekhemikhali kunye nokuveliswa kombane kunye nokhuseleko lokusingqongileyo, unikezelo lwamanzi kunye nokuhanjiswa kwamanzi kunye nezinye iinkqubo zobunjineli zokuthutha. iintlobo ngeentlobo zolwelo lwemithombo yeendaba ezidlayo, ezingadlekiyo kumbhobho, ezisetyenziselwa ukulawula kunye nokunqumla ukuhamba kwemithombo yeendaba.
Ivalve yesangolilungu lokuvula kunye nokuvala isango, indlela yokuhamba yesango i-perpendicular ukuya kwicala le-fluid, i-valve yesango ingasetyenziselwa kuphela ukuvuleka ngokupheleleyo kunye nokuvala ngokupheleleyo, akusebenzi kwiiparameters zomnyango kwaye ezahlukeneyo. Ukuphucula ubugcisa bayo, wenze i-angle yendawo yokutywina ekuqhubeni ukutenxa, eli sango libizwa ngokuba yi-elastic gate.
Xa ivalve yesango ivaliwe, umphezulu wokutywina unokuthembela kuphela kuxinzelelo oluphakathi ukutywinwa, oko kukuthi, ukuthembela kuphela kuxinzelelo oluphakathi kuya kuba yindawo yokutywina yesango ukuya kwelinye icala lesihlalo ukuqinisekisa ukuba indawo yokutywina. komhlaba wokutywina, onokuzitywina. Uninzi lwevalve yesango isetyenziselwa ukunyanzela ukutywinwa, oko kukuthi, xa ivalve ivaliwe, ukuxhomekeka kumandla angaphandle ukunyanzela isango kwisitulo sevalve ukuqinisekisa ukuba indawo yokutywina yokutywinwa.
Intshukumo: Isango levalve yesango elinesiqu sevalve yentshukumo yomgama, ekwaziwa njengeivalve yesango lesiqu esinyukayo. Ivalve yesango isiqu se nut kwisango, ukujikeleziswa kwevili lesandla kuqhuba ukujikeleza kwesiqu sevalve, ukuze isango linyuswe, le valve ibizwa ngokubaivalve yesango ye-nrs.
