Yintoni ivalvu yebhola edadayo yombane?
A Ivalve yeBhola edadayoisebenzisa ibhola ejikelezayo kunye nesiqu esibonelela ngolawulo lokuhamba komoya ngaphakathi nangaphandle.
IUmbane ivalvu yebhola edadayosebenzisa uxinzelelo lwendalo lomgca ukucinezela nokuvala ibhola kwisihlalo esisezantsi komlambo. Uxinzelelo lomgca luvezwa kwindawo engaphezulu - ubuso bonke obuphezulu bebhola, obuyindawo elingana nobukhulu bombhobho wokwenyani.
Xa ivalvu ibekwe apho imbobo ilungelelaniswe khona kwicala elifanayo nombhobho, ikwindawo evulekileyo, kwaye ulwelo lunokudlula ngezantsi. NORTECHIvalvu yebhola edadayoyimveliso entsha eyenziwe ngokuguqula ivalvu eqhelekileyo kunye nokwamkelwa komgangatho wamazwe ngamazwe ohlaziyiweyo.
A Umbane ivalvu yebhola edadayoIvalvu 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 ukumelana nomsebenzi womthwalo kuba uxinzelelo lokutywina luvezwe yiringi yesihlalo. Ngenxa yokungafumaneki kwezinto zesihlalo ezisebenza kakuhle, ivalvu yebhola edadayo isetyenziswa kakhulu xa kusetyenziswa uxinzelelo oluphakathi okanye oluphantsi.
Iimpawu eziphambili ze-NORTECH Electric 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 kwisixhobo esivuthayo okanye esiqhumayo. Iringi yesitywina esingatshiyo ibekwe phakathi kwebhola nesihlalo ukuze emva kokuba isihlalo sevalvu sitshisiwe, isixhobo siya kuyityhala ibhola ngokukhawuleza siye kwiringi yesitywina yesinyithi esezantsi ukuze senze isakhiwo sokuvala isinyithi ukuya kwisinyithi esinokulawula ngokufanelekileyo ukuvuza kwevalvu. Ukongeza, i-gasket yesitywina yeflange ephakathi, enokuqinisekisa ukutywinwa nokuba kuphantsi kobushushu obuphezulu.
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.

4. Ukutywinwa okuthembekileyo kweValve Stem
Isiqu senziwe ngegxalaba ezantsi ukuze lingaphumi yi-medium nokuba imeko imbi kakhulu njengokunyuka koxinzelelo ngaphakathi kwevalvu, ukungaphumeleli kweplate ye-gland njl. Ukongeza, ukuze kuthintelwe ukuvuza emva kokuba i-stem packing itshile xa kutsha, i-thrust bearing ibekwa kwindawo apho i-stem shoulder kunye nomzimba zidibana khona ukuze zenze isihlalo sokutywina esingasemva. Amandla okutywina e-reverse seal aya kwanda ngokwenyuka koxinzelelo oluphakathi, ukuqinisekisa ukutywina okuthembekileyo kwe-stem phantsi koxinzelelo olwahlukeneyo, ukuthintela ukuvuza kunye nokuthintela ukusasazeka kwengozi.
