3 Ukuba uyazikhethela
3.1 Uhlobo
Ivalve yebhabhathane inezakhiwo ezahlukeneyo ezifana ne-eccentric enye, uhlobo lwepleyiti ethambekele, uhlobo lomgca osembindini, i-double eccentric kunye ne-triple eccentric.Uxinzelelo oluphakathi lusebenza kwi-valve shaft kunye nokuhamba ngepleyiti yebhabhathane.Ngoko ke, xa ukuchasana kokuhamba koxinzelelo oluphezulu kunye nobukhulu obuncinci bukhulu, ububanzi be-shaft kunye nobukhulu beplate yebhabhathane buya kwanda ngokufanelekileyo.Ukuba iivalve zesango, iivalve zebhola okanye iivalve zeglowubhu zisetyenzisiwe, ukusuka kwimiba yokutywinwa kunye nokumelana nokuhamba Uhlalutyo lufanelekile ngakumbi kune-butterfly valve.

Kwiminyaka yakutshanje, ukuvela kweevalve zesango ezithambileyo kwiinkqubo zamanzi kuye kwaphucula iintsilelo zeevalvu zesango ekulula ukuchithwa.Ukuchasana nokuhamba kwayo kuncinci, kwaye inokulungiswa kwi-intanethi.Ifaneleke kakhulu kwi-diameters encinci kunye nephakathi, ngoko isetyenziswe ngokuthe ngcembe.
3.2 Izibini zokutywina
Iinzuzo eziphambili zentsimbi yokutywina i-butterfly valve kukutywinwa okuthembekileyo, ubomi obude, ukumelana nobushushu obuphezulu, akukho lula ukonakalisa kunye nokukrazula, kunye noxinzelelo oluphezulu lokuthwala amandla.Ke ngoko, isetyenziswe ngokubanzi kwiminyaka yakutshanje, ngakumbi kwiindawo eziphambili zeenkqubo zobunjineli.Ukuba ivalve yebhabhathane yokutywina ethambileyo yerabha iyilwe kakuhle kwaye yenziwe, inokutywinwa kakuhle, kwaye idiameter enkulu inokutshintshwa ngokulula kwi-intanethi.Nangona kunjalo, i-rubber ineengxaki zokuguga kwaye ingasetyenziselwa kuphela kwiimeko zokusebenza apho iqondo lokushisa lingekho phezulu, ngoko lisetyenziswa ngokubanzi kumanzi ompompo kunye neenkqubo zokubonelela ngamanzi.

Iivalve zebhabhathane zokutywina zentsimbi zangaphandle zikwasetyenziswa kwizikhululo zokumpompa, iicondensers, iinkqubo zokutsalwa komphunga kunye neenkqubo zokutshintshiselana kobushushu kwizityalo zamandla ashushu.Izityalo zamandla enyukliya zikwasetyenziselwa ukwahlula iqokobhe loxinzelelo, iinkqubo zokutshiza kunye nebrine, njl. njl., ukwahlulwa kogcino lwe-oyile kunye nomphunga kwiinkqubo zokusulungekisa i-petroleum.Ivalve yokubonelela, inkqubo ye-desulfurization kunye nonyango lwegesi yomsila, ukuqhekeka kwe-thermal kunye neyunithi ye-catalytic.Kukho nezityalo ze-petrochemical, i-cryogenic, i-slurry kunye ne-papermaking systems.
Kubushushu obuphakathi kunye neemeko zoxinzelelo oluphakathi, kungcono ukusebenzisa iivalve zebhabhathane zokutywina ngentsimbi.Kwiindawo ezifuna ukuthembeka okuphezulu, ubomi obude, kunye nokutshintshwa kwexesha elide, i-valve butterfly etywiniweyo kufuneka isetyenziswe.
Kwivalve esetyenziselwa ubushushu obuqhelekileyo bamanzi, ukuba ayifuni kakhulu, ayiyi kutshintshwa ixesha elide okanye apho kungenakulungeleka ukutshintshwa, kuyacetyiswa ukuba uthabathe i-valve butterfly ene-soft seal structure.Ukuba umgangatho werabha unokuqinisekiswa, iivalvu zebhabhathane ezinobubanzi obukhulu zamanzi kufuneka zibe zizivalo zebhabhathane ezihlala irabha.
4 Isiphelo
Ukuvela okuqhubekayo kobuchwepheshe obutsha kunye nezinto ezintsha kuya kuphucula ukusebenza kwesakhiwo sevalve yebhabhathane, ukwandisa uluhlu lwesicelo sevalve yebhabhathane, kwaye ubeke phambili iimfuno ezihlaziyiweyo zoyilo kunye nokukhethwa kwevalve yebhabhathane.

I-Nortech ngomnye wabavelisi abakhokelayo bevalvu yeshishini e-China kunye nesiqinisekiso somgangatho we-ISO9001.
