DN1200 PN10 metala noho ductile hao Puka puka, (BS5150 Me bypass & Bevel Gear)

ʻO DN1200 PN10 metala noho ductile iron Gate valve, (BS5150 With bypass & Bevel Gear) By pass valve he mea pale ia no ka pahu nui e pale ai i ka nui o ka pale ʻana ma muli o ka ʻokoʻa o ka puʻe ma waena o ka mua a me ke kua o ka pahu. ʻaʻole maʻalahi ka wehe ʻana o ka valve, ʻoi aku ka nui o ke anawaena o ke awa nui a i ʻole ka paipu kiʻekiʻe.Ma mua o ka weheʻiaʻana o ka pipeline kiʻekiʻe, ua hoʻomahaʻia ke kaomi ma o ka valve bypass e pale i ka hoʻokomo kokeʻana o ke kiʻekiʻe kiʻekiʻe a me ka hopena i ka pipeline ma lalo o ka valve.A i ʻole ʻoi aku ka nui o ka ʻokoʻa o ke kaomi ma waena o ka valve a nui loa ka torque.No ka pale ʻana i ka pōʻino o ka valve ma ka torque, e wehe i ka valve bypass e hoʻomaha i ke kaomi mua, a laila wehe i ka valve nui.

Hoʻohana ʻia e like me ka pipeline backup, ʻo ka pōmaikaʻi nui loa i ka wā i pau ʻole ai ka valve nui a pono e mālama ʻia, hiki ke wehe ʻia e ka bypass valve circulation, a ʻaʻole pili i ka hana maʻamau.
