I-valve yebhola edadayo ekumgangatho ophezulu yoMzi-mveliso oPhezulu Umthengisi wefektri waseTshayina Umvelisi
Yintoni ivalvu yebhola edadayo ngesandla?
Ivalvu yebhola edadayo esebenzisa isandla isebenzisa ibhola ejikelezayo kunye nesiqu esibonelela ngolawulo lokuhamba komoya ngaphakathi nangaphandle.
IIvalvu yebhola edadayo ngesandlasebenzisa uxinzelelo lwendalo lomgca ukucinezela nokuvala ibhola kwisihlalo esisezantsi komlambo. Uxinzelelo lomgca luvezwa kwindawo engaphezulu - ubuso bonke obuphezulu bebhola, obuyindawo elingana nobukhulu bombhobho wokwenyani.
AIvalvu yebhola edadayo ngesandlaIvalvu enebhola yayo edadayo (engalungiswanga yi-trunnion) ngaphakathi komzimba wevalvu, iyahamba iye kwicala elisezantsi kwaye ityhale ngamandla kwisihlalo phantsi koxinzelelo oluphakathi ukuqinisekisa ukuthembeka kokutywina. Ivalvu yebhola edadayo inesakhiwo esilula, ukusebenza kakuhle kokutywina kodwa izixhobo zesihlalo ziyafuneka ukuze zimelane nomthwalo womsebenzi kuba uxinzelelo lokutywina luvezwe yiringi yesihlalo.
Xa ivalvu ibekwe apho imbobo ilungelelaniswe khona kwicala elifanayo nombhobho, ikwindawo evulekileyo, kwaye ulwelo lunokudlula ngezantsi. NORTECHIvalvu yebhola edadayo ngesandla yimveliso entsha eyenziwe ngokuguqula ivalvu eqhelekileyo kunye nokwamkelwa komgangatho wamazwe ngamazwe ohlaziyiweyo.
Iimpawu eziphambili ze-NORTECHManual floating ball valve?
1. Uyilo lweSitulo esiKhethekileyo
Sisebenzisa uyilo lwesakhiwo seringi yesitywina esiguquguqukayo sevalvu yebhola edadayo. Xa uxinzelelo oluphakathi luphantsi, indawo yoqhagamshelwano lweringi yesitywina kunye nebhola incinci. Iya kunciphisa ukungqubana kunye ne-torque yokusebenza kwaye iqinisekise ukuqina ngexesha elinye. Xa uxinzelelo oluphakathi lunyusiwe, indawo yoqhagamshelwano lweringi yesitywina kunye nebhola iba nkulu kunye nokuguquguquka kwe-elastic kweringi yesitywina, ukuze iringi yesitywina ikwazi ukumelana nempembelelo ephezulu ephakathi ngaphandle kokonakala.
2. Uyilo lweSakhiwo esingatshiyo
Kwimeko yomlilo ngexesha lokusetyenziswa kwevalvu, iringi yesihlalo eyenziwe nge-PTFE okanye ezinye izinto ezingezizo ezesinyithi iya kubola okanye yonakale phantsi kobushushu obuphezulu kwaye oko kuya kubangela ukuvuza okukhulu kolwelo, kuyingozi kakhulu kwindawo etshayo okanye eqhumayo. Iringi yesitywina engatshiyo ibekwe phakathi kwebhola nesihlalo ukuze emva kokuba isihlalo sevalvu sitshisiwe, le ndawo iya kuyityhala ibhola ngokukhawuleza iye kwiringi yesitywina yesinyithi esezantsi ukuze yenze isakhiwo sokuvala isinyithi ukuya kwisinyithi esinokulawula ngokufanelekileyo ukuvuza kwevalvu. Ukongeza, i-gasket yesitywina seflange ephakathi, enokuqinisekisa ukutywinwa nokuba kuphantsi kobushushu obuphezulu. Uyilo lwesakhiwo esingatshiyo sevalvu yebhola edadayo luhambelana neemfuno ze-APl607, APl6FA, BS 6755 kunye neminye imigangatho.

3. Ulwakhiwo oluchasene nokungashukumi
Ivalvu yebhola yenzelwe isakhiwo esichasene nokunganyakazi kunye nesixhobo sokukhupha umbane ongashukumiyo ukuze senze ngokuthe ngqo umjelo ongashukumiyo phakathi kwebhola nomzimba ngesiqu ukuze kukhutshwe umbane ongashukumiyo oveliswa kukungqubana kwebhola nesihlalo, kuthintelwe umlilo okanye ukuqhuma okunokubangelwa kukukhazimla okungashukumiyo kunye nokuqinisekisa ukhuseleko lwenkqubo.

5. Ukuthintela ukutshixa kunye nokusetyenziswa gwenxa
Ivalvu yebhola yesandla ingatshixwa ngesitshixo kwindawo evulekileyo okanye evaliwe ngokupheleleyo. Isixhobo sokubeka esivulekileyo nesivaliweyo esingu-90° esinomngxuma wokutshixa senzelwe ukuthintela ukungasebenzi kakuhle kwevalvu okubangelwa zii-opreators ezingagunyaziswanga, kwaye sinokuthintela ukuvulwa okanye ukuvalwa kwevalvu, okanye ezinye iingozi ezibangelwa kukungcangcazela kwepayipi okanye izinto ezingalindelekanga. Isebenza kakhulu ngakumbi kwi-oyile evuthayo neqhumayo, iikhemikhali kunye nemibhobho yokusebenza yezonyango okanye ityhubhu yasentsimini. Inxalenye esentloko yesiqu efakwe nesiphatho isebenzisa uyilo oluthe tyaba. Apho ivalvu ivuliwe, isiphatho sihambelana nombhobho, kwaye izibonakaliso zokuvala zevalvu ziqinisekisiwe ukuba zichanekile.
