API 6D/API 608 High Pressure Casting/Forging Bw Floating/Trunnion Dbb Manual/Electrical/Pneumatic Cryogenic Eccentric Semi-Ball Valve
Yintoni ivalve yebhola yetrunnion yeDBB?
DBB trunnion ibhola Valveyivalve yebhola eyenzelwe ngokukhethekileyo.
Ngokuphathelele i-Double block kunye nenkqubo yevalve yokopha, kukho iinkcazo ezimbini nge-API6D kunye ne-OSHA.
I-OSHA ichaza i-aIvalve yebhola yetrunnion yeDBBInkqubo "njengokuvalwa komgca, umbhobho, okanye umbhobho ngokuvala kunye nokutshixa okanye ukumaka iivalve ezimbini ezingaphakathi kunye nokuvula kunye nokutshixa okanye ukumaka i-drain okanye i-valve ye-vent kumgca phakathi kweevalve ezimbini ezivaliweyo".
iNORTECH DBB trunnion ibhola valveyenzelwengokudibanisa iivalve ezimbini zibe ngumzimba omnye, uyilo lwe-twin-valve lunciphisa ubunzima kunye neendlela ezinokuvuza ezinokuvuza ngelixa uhlangabezana neemfuno ze-OSHA zebhloko ephindwe kabini kunye negazi.
I-API 6D ichaza iSistim yevalve yebhola yetrunnion yeDBB “njengevalve enye eneendawo zokuhlala ezimbini ezithi, kwindawo evaliweyo, inike isitywina ngokuchasene noxinzelelo oluvela kwiziphelo zombini zevalve ngendlela yokuthengisa/yokopha umngxuma phakathi kwendawo yokuhlala. ”
Iimpawu eziphambili ze-DBB trunnion ball valve
Iyunithi enyeIvalve yebhola yetrunnion yeDBB inikeza ibhloko ephindwe kabini kunye negazi kwivalve enye.Esi simbo sinokubeka imibhobho yodwa kumacala omabini evalvu ukuze kuphume/ ukophe umngxuma wevalve phakathi kwezihlalo.
Ukusebenzisa iyunithi enye ibhloko ephindwe kabini kunye nenkqubo yevalve yokuphuma kwegazi ngokuchasene neevalvu ezi-3 ezahlukileyo konga ixesha lofakelo, ubunzima kwinkqubo yokubhobhoza, kunye nendawo.Olu luyilo lukwanazo iingenelo zokusebenza,
- Kukho iindlela ezimbalwa zokuvuza ezinokubakho ngaphakathi kwebhloko ephindwe kabini kunye necandelo lokopha lombhobho.
- Zonke iinxalenye zevalve zigcinwe kwiyunithi enye, indawo efunekayo yofakelo iyancitshiswa kakhulu ngaloo ndlela ikhulula indawo yezinye iziqwenga zezixhobo ezibalulekileyo.
- Amaxesha amafutshane okukhupha amanzi ayafuneka.
Ivalve yebhola yetrunnion yeDBB yindibaniselwano yebloko enye okanye ngaphezulu / iivalvu zokwahlula, ngokuqhelekileyo iivalvu zebhola, kunye nenye okanye ngaphezulu kweevalvu zokopha/i-vent, ngokuqhelekileyo iivalvu zebhola okanye iinaliti.Injongo yenkqubo yevalve yebloko kunye neyokopha kukwahlula okanye ukuthintela ukuhamba kolwelo kwisixokelelwano ukuze ulwelo olusuka phezulu lungafikeleli kwamanye amacandelo enkqubo esezantsi komlambo.Oku kuvumela iinjineli ukuba zikhuphe igazi okanye zikhuphe okanye zikhuphe ulwelo oluseleyo kwinkqubo kwicala elisezantsi ukuze zenze uhlobo oluthile lomsebenzi (ulungiso / ukulungiswa / ukutshintshwa), isampulu, ukuphambukiswa kokuqukuqela, ukutofwa kwemichiza, ukukhangela imfezeko yokuvuza njl.njl. .
Ukucaciswa kobugcisa bevalve yebhola yetrunnion yeDBB
uMboniso weMveliso:Ivalve yebhola ye-DBB yetrunnion
Ukusetyenziswa kwevalve yebhola yetrunnion yeDBB
Iivalvu zebhola zetrunnion zeDBBzisetyenziswa kakhulu kwishishini leoli kunye negesi, kodwa zinokuba luncedo kwamanye amashishini amaninzi.Ngokuqhelekileyo isetyenziswa apho ukopha i-valve cavity kufuneka, apho imibhobho ifuna ukwahlulwa ukuze ilungiswe, okanye kuyo nayiphi na enye yezi meko:
- Thintela ukungcoliseka kwemveliso.
- Susa izixhobo kwinkonzo yokucoca okanye ukulungiswa.
- Ukulinganisa imitha.
- Isixhobo sodwa esifana nezalathisi zoxinzelelo kunye neegeji ze-lever.
- Inkqubo yokuqala umphunga.
- Vala kwaye ukhuphe izixhobo zokulinganisa uxinzelelo.
