Say prinsipyo na pantratrabaho tan say pangipaalagey tan pangipaalagey na rubber seated butterfly valve

Saygoma ya akayurong ya balbula na kulibangbanget sakey a klase na balbula ya manguusar na pabilog a butterfly plate bilang panlukas tan pansara na parte tan manpapalikdo ed balbula pian nalukasan, nasara tan na-adjust so fluid channel. Say plato na kulibangbang nagoma ya akayurong ya balbula na kulibangbanget akapuesto ed direksion na diametro na tubo. Diad silindrikon kanal nagoma ya akayurong ya balbula na kulibangbanglaman, say singa disc ya butterfly plate et onliliber ed axis, tan say rotation angle et walad baetan na 0° anggad 90°. No onliber itan ed 90°, say balbula et sigpot ya lukas.

Saray pasen a pangipaalagey tan pangipaalagey

1. Say posisyon na pangipuesto, katagey, tan direksion na pangiloob tan pangipaway et nepeg ya makatunongan ed saray kakaukolanen ed desinyo, tan say koneksion et nepeg ya malet tan malet.

2. Parad amin a klase na manual a balbula ya akapuesto ed thermal insulation pipeline, say panangawit to et nepeg ya ag-onleksab.

3. Kaukolan ya gawaen so visual inspection antis ya i-install so balbula, tan say nameplate na balbula et nepeg ya makatunongan ed saray kakaukolanen na kaplesan ya estandarte na bansa ya “General Valve Mark” GB12220. Parad balbula ya say working pressure to et mas atagey nen say 1.0MPa tan walay papel to ed panagputot na manunan tubo, say biskeg tan malet ya performance test et nepeg ya gawaen antis ya i-install, tan nayarin usaren itan kayari na pakapasa ed test. Legan na strength test, say test pressure et 1.5 beses nen say nominal pressure, tan say karukey to et ag onkulang ed 5 minuto. Say kawalaan na balbula tan say pangikarga to et nepeg ya kualipikado ya anggapoy onlelesa. Diad tightness test, say test pressure et 1.1 beses nen say nominal pressure; say test pressure et nepeg ya makaabot ed saray kakaukolanen na GB50243 standard legan na test duration, tan say valve disc sealing surface et kualipikado no anggapoy leakage.

Saray punto na panagpili na produkto

1. Say manunan control parameters nagoma ya akayurong ya balbula na kulibangbangsaray detalye tan sukat.

2. Nayarin paandaren itan na mano-mano, de-koryente odino panamegley na zipper, tan nayarin i-fix ed antokaman ya anggulo ya walad loob na 90°.

3. Lapud saksakey so shaft tan saksakey so plato na balbula, limitado so kapasidad na panag-awit, tan antikey so bilay na balbula diad silong na baleg a pandumaan na presyon tan baleg ya flow rate.
