O le a le BS1873 globe valve?
BS1873 kelope valve
o se tasi o mamanu sili ona lauiloa o valves kelope, mo le US ma le API system.o totonu lautele, mea, o le faafesagaʻi, puipui mafiafia, vevela vevela, o loʻo faʻamatalaina e le ASME B16.34.
o leBS1873 kelope valvee mafai ona faʻaaogaina mo faʻalavelave faʻalavelave faʻapea foʻi. E tele tino faʻapipiʻi nofofua e faʻaogaina le fale puipui poʻo le faʻapipiʻiina o le fausaga e taofi ai le nofoa-mama, tuʻuina atu le faʻaogaina o le valve faʻapipiʻi, ma tuʻuina atu se auala mo le faʻavaeina o uiga faʻafefe faʻapitoa.e mafai foi ona faigofie ona suia e ala i le suia o vaega tipi e sui le uiga tafe po o le tuuina atu faaitiitia-gafatiatafe, faʻaitiitia le pisa, poʻo le faʻaitiitia poʻo le faʻaumatiaina o le cavitation.
ASME Globe Valve Body Patterns, e tolu fa'asologa o le tino po'o mamanu mo valve Globe, e ta'ua:
- .
- 2).Mamanu Angle
- 3). Oblique Pattern (fa'aigoa o Wye Pattern po'o Y – Pattern)
Fa'avae Galuega aBS1873 kelope valve
O le valve globe e aofia ai se tisiketi feavea'i ma se nofoa mama tumau i totonu o se tino lapotopoto.O le nofoa o le valve globe o loʻo i le ogatotonu ma tutusa ma le paipa, ma o le avanoa i le nofoa e tapunia ma le disk.pe a vili lima le uili lima po'o se fa'agaoioiga, e fa'atonutonuina le fa'agaoioiga o le tisiketi (fa'alalo pe si'i a'e) e ala i le a'a o le valve.Pe a nofo le tisiketi valve kelope i luga o le mama nofoa, e taofi atoa le tafe.
Vaega autu ole BS1873 globe valve
- 1) lelei fa'amaufa'ailoga
- 2). Puupuu malaga mamao o le tisiketi (stroke) i le va o avanoa tatala ma tapunia,ASME globe valvee lelei pe afai e tatau ona tatala ma tapuni soo le valve;
- 3).Ole ASME globe valve e mafai ona fa'aoga e fai ma fa'agata-siaki alavai e ala i le suia o le mamanu teisi.
- 4).To lo'o i ai le tele o mea e mafai ona maua i tee, Wye, ma sitaili o le tino.
