Dbb Ball Valve Ibhlokhi kabini kunye neBleed Ball Valve China Manufacture
Yintoni ivalve yebhola ye-DBB?
Ibhlokhi ephindwe kabini kunye neValve yeBhola eyophayoyivalve yebhola eyenzelwe ngokukhethekileyo.
Ngokubhekiselele kwi-Double block kunye nenkqubo yevalve yokopha, kukho iinkcazo ezimbini nge-API6D kunye ne-OSHA.
I-API 6D ichaza aIbhlokhi ephindwe kabini kunye neValve yokuBophaInkqubo "njengevalve enye eneendawo zokuhlala ezimbini ezithi, kwindawo evaliweyo, inike itywina ngokuchasene noxinzelelo oluvela kwiziphelo zozibini zesivalo ngendlela yokuthengisa/yokopha umngxuma phakathi kwendawo yokuhlala."
I-OSHA ichaza i-aIbhlokhi ephindwe kabini kunye neValve yokuBophaInkqubo "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".
iIbloko ephindwe kabini ye-NORTECH kunye nevalve yebhola eyophayoyenzelwengokudibanisa 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.
Iimpawu eziphambili zevalve yebhola yeDBB
Iyunithi enyeDBB Ball Valveinikeza ibhloko ephindwe kabini kunye negazi kwivalve enye.Esi simbo sinokwahlula imibhobho kumacala omabini evalvu ukuze kuphume/ ukophe umngxuma wevalve phakathi kwezihlalo.
DBB Ball Valveludibaniso lwebloko okanye iivalve zokuzahlula, ngokuqhelekileyo iivalvu zebhola, kunye nenye okanye ngaphezulu kweevalvu zokopha/zokuphuma, 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. .
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.
- Iivalvu zigcwele kunye ne-orifice ehambayo engaphazamisekiyo baye bafumana ukuhla koxinzelelo olungenamsebenzi kwiyunithi.
- Imibhobho apho ezi zivalo zifakwe khona nazo zinokufakwa iihagu ngaphandle kweengxaki.
Ukucaciswa kobugcisa bevalve yebhola ye-DBB
uMboniso weMveliso:Ivalve yebhola yeDBB
Ukusetyenziswa kwevalve yebhola yeDBB
Ivalve yebhola yeDBBzisetyenziswa 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 imeko:
- Thintela ukungcoliseka kwemveliso.
- Susa izixhobo kwinkonzo yokucoca okanye ukulungiswa.
- Ukulinganisa imitha.
- Isixhobo sodwa esifana nezalathisi zoxinzelelo kunye ne-lever gauges.
- Inkqubo yokuqala umphunga.
- Vala kwaye ukhuphe izixhobo zokulinganisa uxinzelelo.
