Ibhlokhi ephindwe kabini kunye neValve yeBhola eyophayo
Yintoni i-Double block kunye nevalve yebhola eyophayo?
Ibhlokhi ephindwe kabini kunye neValve yeBhola eyophayoyivalve yebhola eyenzelwe ngokukhethekileyo.
Ngokuphathelele i-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 zebhloko ephindwe kabini kunye nevalve yebhola eyophayo
Ibhlokhi ephindwe kabini kunye neValve yeBhola eyophayoyindibaniselwano 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. .
Iyunithi enyeIbhlokhi ephindwe kabini kunye neValve yokuBophainikeza 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.
- Iivalvu zigcwele kunye ne-orifice ehambayo engaphazamisekiyo baye bafumana ukuhla koxinzelelo olungenamsebenzi kwiyunithi.
- Imibhobho apho ezi zivalo zifakwe khona nazo zinokufakwa iihagu ngaphandle kweengxaki.
- Zonke iinxalenye zevalve zigcinwe kwiyunithi enye, indawo efunekayo yofakelo iyancitshiswa kakhulu ngaloo ndlela ikhulula indawo yezinye iziqwenga zezixhobo ezibalulekileyo.
- Amaxesha amafutshane okukhupha amanzi ayafuneka.
Ubuchwephesha obucacileyo bebloko ephindwe kabini kunye nevalve yebhola eyophayo
uMboniso weMveliso:
Ukusetyenziswa kwebloko ephindwe kabini kunye neevalvu zebhola ezophayo
Ibloko ephindwe kabini kunye neevalvu zebhola ezophayozisetyenziswa 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.
- Inkonzo yolwelo kufutshane nemijelo yamanzi okanye koomasipala.
- Ugqithiso kunye nokugcinwa.
- Isitofu samachiza kunye nesampulu.
- Isixhobo sodwa esifana nezalathisi zoxinzelelo kunye neegeji ze-lever.
- Inkqubo yokuqala umphunga.
- Vala kwaye ukhuphe izixhobo zokulinganisa uxinzelelo.
