I-valve yeglobe ye-ASME B16.34 yoMzi-mveliso oPhezulu waseTshayina
Yintoni ivalvu yeglobhu ye-ASME B16.34?
Ivalvu yeglobhu ye-ASME B16.34yenye yezona ndlela zidumileyo zoyilo lweevalvu zeglobe, zenkqubo ye-US kunye ne-API. Ububanzi bangaphakathi, izixhobo, ubuso ngobuso, ubukhulu bodonga, ubushushu boxinzelelo, zichazwa yi-ASME B16.34.
Ukongeza, kuxhomekeke kuyilo lwesihlalo kunye nediski, umthwalo wezihlaloIvalvu yeglobhu ye-ASME B16.34inokulawulwa kakuhle ngesiqu esikrufulwe ngezikrufu.
iIvalvu yeglobhu ye-ASME B16.34ingasetyenziselwa neenjongo zokuqhobosha. Iivalvu ezininzi ezihlala umntu omnye zisebenzisa ulwakhiwo lwekheji okanye uhlobo lwe-retainer ukugcina iringi yesihlalo, ukubonelela ngesikhokelo seplagi yevalvu, kunye nokubonelela ngeendlela zokuseka iimpawu ezithile zokuhamba kwevalvu. Ingatshintshwa ngokulula ngokutshintsha iindawo zokusika ukutshintsha uphawu lokuhamba okanye ukubonelela ngomthamo ophantsi.ukuhamba, ukunciphisa ingxolo, okanye ukunciphisa okanye ukuphelisa i-cavitation.
Iipateni zomzimba ze-ASME Globe Valve, kukho iipateni ezintathu eziphambili zomzimba okanye uyilo lweevalvu zeGlobe, ezizezi:
- 1). Ipateni eQhelekileyo (ekwaziwa ngokuba yiTee Pattern okanye iT – Pattern okanye iZ – Pattern)
- 2) .Iphethini ye-Angle
Umgaqo wokusebenza oIvalvu yeglobhu ye-ASME B16.34
Ivalvu yeglobe yenziwe yidiski eshukumayo kunye nesihlalo sendandatho esimileyo emzimbeni ongqukuva. Isihlalo sevalvu yeglobe siphakathi kwaye sihambelana nombhobho, kwaye umngxuma osesihlalweni uvalwa ngediski. Xa ivili lesandla lijikeleziswa ngesandla okanye yi-actuator, intshukumo yediski ilawulwa (yehliswa okanye iphakanyisiwe) ngesiqu sevalvu. Xa idiski yevalvu yeglobe ihleli phezu kwendandatho yesihlalo, ukuhamba kwamanzi kuyeka ngokupheleleyo.
Eyona nto iphambili kwivalvu yeglobhu ye-ASME B16.34
- 1) .Izakhono ezilungileyo zokutywina
- 2). Umgama omfutshane wokuhamba kwediski (stroke) phakathi kweendawo ezivulekileyo nezivaliweyo,Iivalvu zeglobhu ze-ASMEzilungele ukuba ivalvu kufuneka ivulwe kwaye ivalwe rhoqo;
- 3).Ivalvu yeglobhu ye-ASME ingasetyenziswa njengevalvu yokujonga ukumisa ngokutshintsha uyilo kancinci.
- 4).TNazi iindlela ezahlukeneyo zobuchule ezifumanekayo kwiindlela ze-tee, Wye, kunye ne-angle body.
- 5).Ukuyilungisa nokuyifaka kwakhona izihlalo ngokulula, ngeenjongo ezahlukeneyo.
