Kodi valavu ya mpira wa DBB trunnion ndi chiyani?
DBB trunnion mpira Valvendi valavu yapadera yopangidwa ndi mpira.
ponena za Double block and bleed valve system, pali matanthauzo awiri a API6D ndi OSHA.
OSHA imatanthauzira aDBB trunnion mpira valveDongosolo ngati "kutseka kwa mzere, njira, kapena chitoliro potseka ndi kutseka kapena kuyika ma valve awiri olowera mkati ndi kutsegula ndi kutseka kapena kuyika chizindikiro cha kukhetsa kapena kutulutsa mpweya pakati pa ma valve awiri otsekedwa".
ndiNORTECH DBB trunnion mpira valvezopangidwapophatikiza ma valve awiri kukhala thupi limodzi, mapangidwe a valve amapasa amachepetsa kulemera ndi njira zomwe zingathe kutuluka pamene akukumana ndi zofunikira za OSHA pawiri block ndi magazi.
API 6D imatanthawuza DBB trunnion ball valve System ngati "valavu imodzi yokhala ndi malo awiri okhalamo omwe, pamalo otsekedwa, amapereka chisindikizo motsutsana ndi kupanikizika kuchokera kumalekezero onse a valve ndi njira yogulitsira / kukhetsa magazi pakati pa malo okhala. ”
Zinthu zazikulu za DBB trunnion mpira valve
Single UnitDBB trunnion mpira valve amapereka chipika iwiri ndi magazi mu valavu imodzi.Kalembedwe kameneka kamatha kusiyanitsa mipope mbali zonse ziwiri za valavu kuti itulutse / kutulutsa magazi pakati pa mipando.
Kugwiritsa ntchito kagawo kakang'ono kawiri ndi ma valve otulutsa magazi motsutsana ndi ma valve atatu osiyana kumapulumutsa nthawi yoyika, kulemera kwa mapaipi, ndi malo.Mapangidwe awa alinso ndi maubwino ogwiritsira ntchito,
- Pali njira zochepera zotayikira mkati mwa midadada iwiri komanso gawo lotulutsa magazi la mapaipi.
- Zigawo zonse za valve zimayikidwa mu unit imodzi, malo ofunikira kuti akhazikitsidwe amachepetsedwa kwambiri motero amamasula malo a zida zina zofunika.
- Nthawi yocheperako ndiyofunikira.
DBB trunnion mpira valve Kuphatikizika kwa valavu imodzi kapena zingapo zodzipatula, nthawi zambiri mavavu a mpira, ndi mavavu amodzi kapena angapo otulutsa magazi, nthawi zambiri mavavu a mpira kapena singano.Cholinga cha block and bleed valve system ndikudzipatula kapena kutsekereza kutuluka kwa madzi mu dongosolo kuti madzi otuluka kumtunda asafikire zigawo zina za dongosolo lomwe lili pansi.Izi zimathandiza mainjiniya kukhetsa magazi kapena kutulutsa kapena kukhetsa madzi otsala kuchokera kumadzi otsalira kunsi kwa mtsinje kuti agwire ntchito yamtundu wina (kukonza / kukonza / kusintha), sampuli, kusokoneza madzi, kubayidwa mankhwala, kuwunika kukhulupirika kwa kutayikira etc. .
