Isiqu esinyukayo esithambileyo sokutywinwa kweGroove yeSango iValve eFakelwe umfanekiso

ISithi esinyukayo sokutywina iValve yeSango leGroove

inkcazelo emfutshane:

Ivalve yesango luhlobo lwesivalo apho ilungu elivalayo (isango) lihamba ngokuthe nkqo ecaleni kombindi wetshaneli.Ivalve yesango ingasetyenziselwa kuphela ukuvulwa ngokupheleleyo kunye nokuvala ngokupheleleyo kwipayipi, kwaye ayikwazi ukusetyenziselwa ukulungiswa kunye ne-throttling.

Iinkcukacha zeMveliso

Iithegi zeMveliso

I-valve yesango isetyenziselwa ngokubanzi izixhobo zokusika kunye nobubanzi be-DN ≥ 50mm, kwaye ngamanye amaxesha iivalve zesango nazo zisetyenziselwa ukusika izixhobo ezinobubanzi obuncinci.

Inxalenye yokuvula kunye nokuvala i-valve yesango yisango, kwaye ulwalathiso lokuhamba kwesango luyi-perpendicular ukuya kwicala le-fluid.Ivalve yesango inokuvulwa ngokupheleleyo kwaye ivalwe ngokupheleleyo, kwaye ayikwazi ukulungiswa okanye i-throttled.Isango linemigangatho emibini yokutywina.Imiphezulu emibini yokutywina kweyona ndlela ixhaphakileyo isetyenziswa ivelufa yesango yenze imilo ye wedge.I-engile ye-wedge iyahluka kunye neeparamitha zevalve, idla ngokuba yi-50, kunye ne-2 ° 52' xa ubushushu obuphakathi bungekho phezulu.Isango levalve yesango le-wedge linokwenziwa ngokupheleleyo, elibizwa ngokuba lisango eliqinileyo;ingenziwa kwakhona kwisango elinokuvelisa inani elincinci lokuguqulwa ukuze kuphuculwe ukwenziwa kwayo kwaye kuhlawulele ukuphambuka kwe-angle yokutywinwa komhlaba ngexesha lokucubungula.Ipleyiti ibizwa ngokuba lisango elastiki.Ivalve yesango sesona sixhobo sokulawula ukuhamba okanye ukuhambisa umthamo womgubo, izinto eziziinkozo, izinto eziziinkozo kunye nentwana encinci.Isetyenziswa ngokubanzi kwi-metallurgy, imigodi, izinto zokwakha, ukutya okuziinkozo, imboni yeekhemikhali kunye namanye amashishini ukulawula utshintsho lokuhamba okanye ukunqunyulwa ngokukhawuleza.

Iivalvu zesango zibhekisa ngokukodwa kwiindidi zeevalvu zesango lentsimbi etyhidiweyo, ezinokuthi zohlulwe zibe ziivalvu zesango elinomda, iivalvu zesango ezinxuseneyo, kunye neevalvu zesango le-wedge ngokobume bomphezulu wokutywina.Ivalve yesango inokwahlulwa ibe: uhlobo lwesango elilodwa, uhlobo lwesango eliphindwe kabini kunye nohlobo lwesango elilastiki;ivalve yesango elinxuseneyo linokwahlulwa libe luhlobo lwesango elinye kunye nodidi lwesango eliphindwe kabini.Ngokwendawo yokuma kwentambo yesikhondo sevalve, inokohlulwa ibe ziindidi ezimbini: ivalve yesango lesiqu esinyukayo kunye nevalve yesango yesiqu enganyukiyo.

Xa ivalve yesango ivaliwe, umphezulu wokutywina unokutywinwa kuphela ngoxinzelelo oluphakathi, oko kukuthi, ukuxhomekeka kuxinzelelo oluphakathi ukucinezela indawo yokutywina yeplate yesango ukuya kwisihlalo sevalve kwelinye icala ukuqinisekisa ukutywinwa kwe-valve. umphezulu wokutywina, onokuzitywina.Uninzi lwevalve yesango lunyanzeliswa ukutywinwa, oko kukuthi, xa i-valve ivaliwe, isango kufuneka licinezelwe kwisihlalo se-valve ngamandla angaphandle, ukwenzela ukuba kuqinisekiswe ukutywinwa kwendawo yokutywina.

Isango levalve yesango lihamba ngomgca othe tye onesikhondo sevalve, ebizwa ngokuba yivalve yesango yesikhondo sokuphakamisa (ekwabizwa ngokuba yivalve yesango yesikhondo esinyukayo).Ngokuqhelekileyo kukho intambo ye-trapezoidal kwi-lifter, kwaye ngokusebenzisa i-nut phezulu kwi-valve kunye ne-groove yesikhokelo kumzimba wevalve, intshukumo ejikelezayo iguqulwa ibe yintshukumo yomgca othe ngqo, oko kukuthi, i-torque yokusebenza iyatshintshwa. kwityholo lokusebenza.

Xa i-valve ivuliwe, xa ukuphakama kweplate yesango ilingana no-1: 1 amaxesha ububanzi be-valve, ukuhamba kwe-fluid kuvuliwe ngokupheleleyo, kodwa esi sikhundla asikwazi ukubeka iliso ngexesha lokusebenza.Ekusetyenzisweni okwenyani, i-apex yesikhondo sevalve isetyenziswa njengophawu, oko kukuthi, indawo apho isiqu sevalve singashukumi sithathwa njengendawo yaso evuleke ngokupheleleyo.Ukuze kuqwalaselwe isenzeko sokutshixa ngenxa yotshintsho lobushushu, ngokuqhelekileyo luvuleleke kwindawo ephezulu, kwaye emva koko ujike u-1/2-1 ujike, njengevalve evuleke ngokupheleleyo.Ngoko ke, indawo evulekile ngokupheleleyo ye-valve inqunywe yindawo yesango (oko kukuthi, ukubetha).

Kwezinye iivalve zesango, i-stem nut ibekwe kwipleyiti yesango, kwaye ukujikeleza kwevili lesandla kuqhuba isiqu sevalve ukuba sijikeleze, kwaye iplate yesango iphakanyisiwe.Olu hlobo lwevalve lubizwa ngokuba yivalve yesango ejikelezayo okanye ivalve yesango elimnyama.
