Uhlolojikelele lwe-Rising Stem Fire Elastic Seat Seal Gate Valves
I-Rising stem fire elastic sealing gate valve iyi-valve esetshenziswa ezinhlelweni zokuvikela umlilo, esebenza kahle kakhulu nezici. Okulandelayo kuzokwethula uhlolojikelele, amapharamitha wobuchwepheshe, kanye nezilinganiso zokuxhuma zangaphandle eziyinhloko zevalvu.
1. Uhlolojikelele
I-valve yesango lokuvala isihlalo esinwebekayo se-Minggan Fire Protection ikhiqizwa yi-Shanghai Shenhong Valve Co., Ltd. Le valve isetshenziswa kakhulu ezinhlelweni zokuvikela umlilo, ekwazi ukumelana nokucindezela okukhulu kwamanzi nokuqinisekisa ukuvala okuthembekile uma kwenzeka umlilo. Yenziwe ngezinto ezisezingeni eliphezulu futhi inokumelana nokugqwala okuhle kakhulu namandla emishini.
2. Imingcele yezobuchwepheshe
