Q61F valavu ya mpira wowotcherera wodzaza Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Valavu ya mpira wa weldsd yogwiritsira ntchito nthawi yayitali-tsrm reliabls opsration, palibe kukonza, yosavuta kukhazikitsa, makamaka DN300 imachepetsa kuyika kwa ma valves kumakhala kosavuta, sikungochepetsa mtengo wa zomangamanga, komanso kumapulumutsa nthawi.

Valavu yowotcherera bwino kwambiri imagwiritsidwa ntchito kwambiri mu gasi wamzindawu, kutentha kwamatawuni, petrochemical, zomangamanga, zitsulo, zowongolera pamitundu yonse ya zida zamapaipi, zida zamagetsi ndi zina.

Kuzindikira kuthamanga kwa thupi

ANSI B 16.34 Gawo 7.1
Kukula kwa vavu NPS	Kupanikizika kwa mayeso	Nthawi yoyesera
DN50≥	1:5 nthawi 100 ° CF	15mphindi
DN65-200	Mavoti a AN ST Class	60 masekondi
DN250≤	Max. kuthamanga kwa ntchito	180sekondi
Dziwani kupanikizika kuposa valavu yothamanga kwambiri yogwira ntchito 1.5 nthawi zapamwamba (100F)

1.Seal hydrostatic test: Kupanikizika kuyenera kukhala nthawi zambiri za 1.1 kuposa kugwira ntchito kwa pressare ndi chisindikizo cha hydrastatic test.
