Yintoni ivalvu yebhola edadayo?

A Ivalve yeBhola edadayoisebenzisa ibhola ejikelezayo kunye nesiqu esibonelela ngolawulo lokuhamba komoya ngaphakathi nangaphandle.

Iivalvu yebhola edadayosebenzisa uxinzelelo lwendalo lomgca ukucinezela nokuvala ibhola kwisihlalo esisezantsi. Uxinzelelo lomgca luvezwa kwindawo engaphezulu - ubuso bonke obuphezulu bebhola, obuyindawo elingana nobukhulu bombhobho wokwenyani.

A 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.

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.

Iimpawu eziphambili zevalvu yebhola edadayo ye-NORTECH?

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.

4. Ukutywinwa okuthembekileyo kweValve Stem

Isiqu senziwe ngegxalaba ezantsi ukuze lingaphumi yi-medium nokuba phantsi kwemeko enzima efana nokunyuka koxinzelelo olungaqhelekanga ngaphakathi kwevalvu, ukungaphumeleli kweplate ye-gland njl. Ukongeza, ukuze kuthintelwe ukuvuza emva kokuba i-stem packing itshisiwe 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. Isakhiwo sokutywina se-V type packing senzelwe isiqu, i-V type packing inokutshintsha ngokufanelekileyo amandla okucinezela kunye namandla aphakathi e-gland ibe ngamandla okutywina esiqu. Ngokweemfuno zabasebenzisi, indlela yokucinezela i-disc spring packing elayishwe yi-disk spring ingasetyenziswa ukwenza ukutywina kwe-stem packing kuthembeke ngakumbi.

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.
