Imveliso yobungcali ASME BS1873 cast intsimbi yeglobhu iivalvu zokumisa ivalve China umboneleli wefektri
Yintoni i-BS1873 ivalve yeglowubhu?
Ivalve yeglowubhu ye-BS1873
lolona yilo ludumileyo lweevalvu zeglowubhu, ze-US kunye ne-API system.the ngaphakathi ubukhulu, izixhobo, ubuso ngobuso, ubukhulu bodonga, ubushushu boxinzelelo, zichazwa yi-ASME B16.34.
iIvalve yeglowubhu ye-BS1873ingasetyenziselwa iinjongo zokugobhoza ngokunjalo.Iibhodi ezininzi zevalvu ehleli enye zisebenzisa ikheji okanye ulwakhiwo lwesigcini sokugcina ukugcina isangqa, ukubonelela ngesikhokhelo seplagi yevalvu, kunye nokubonelela ngeendlela zokuseka iimpawu zokuqukuqela kwevalve ethile.Isenokuguqulwa ngokulula ngotshintsho lweziqendu zetrim ukutshintsha uphawu lokuhamba okanye ukunika umthamo oncitshisiweyoukuhamba, ukunciphisa ingxolo, okanye ukunciphisa okanye ukupheliswa kwe-cavitation.
Iipateni zoMzimba we-ASME Globe, kukho iipateni ezintathu eziphambili zomzimba okanye uyilo lweevalvu zeGlobe, ezizezi:
- 1).Ipateni eMiselweyo (ekwabizwa ngokuba yiPateni yeTee okanye iT – Ipateni okanye uZ – Ipateni)
- 2).Ipateni ye-engile
- 3).Ipateni ye-Oblique (ekwaziwa ngokuba yi-Wye Pattern okanye i-Y-Pateni)
Umgaqo wokuSebenza weIvalve yeglowubhu ye-BS1873
Ivalve yeglowubhu yenziwe ngediski eshukumayo kunye nesitulo seringi esimileyo kumzimba ongqukuva.Isihlalo sevalve yeglowubhu siphakathi kwaye sihambelana nombhobho, kwaye ukuvulwa kwesitulo kuvaliwe ngediski.xa i-handwheel ijikelezwa ngesandla okanye nge-actuator, i-disc movement ilawulwa (iyancipha okanye iphakanyiswe) ngokusebenzisa i-valve stem.Xa idiskhi yeglowubhu yeglowubhu ihleli phezu kweringi yesitulo, ukuhamba kuyekiswa ngokupheleleyo.
Eyona nto iphambili ye-BS1873 ivalve yeglowubhu
- 1).Izakhono zokutywina ezilungileyo
- 2) Umgama omfutshane wokuhamba wediski (stroke) phakathi kweendawo ezivulekileyo nezivaliweyo,Iivalvu zeglowubhu ze-ASMEzifanelekile ukuba ivalve kufuneka ivulwe kwaye ivalwe rhoqo;
- 3).Ivalve yeglowubhu ye-ASME ingasetyenziswa njengevalve yokumisa ngokuguqula uyilo kancinane.
- 4).Tnalu uluhlu olubanzi lwezakhono njengoko lufumaneka kwitee, iWye, kunye nezimbo zomzimba ze-engile.
