Amagqabantshintshi ngokunyuka kweStem Fire Elastic Seat Seal Iivalvu zeSango
I-Rising stem fire elastic seat yokutywina i-valve yesango yivalve esetyenziswa kwiinkqubo zokukhusela umlilo, esebenza kakuhle kunye neempawu. Oku kulandelayo kuya kwazisa umboniso, iiparamitha zobugcisa, kunye nemilinganiselo yokudibanisa yangaphandle yevalve.
1. Isishwankathelo
I-valve ye-elastic yesihlalo sokutywinwa kwesango lokuKhuselwa koMlilo iveliswa yi-Shanghai Shenhong Valve Co., Ltd. Le valve isetyenziswa kakhulu kwiinkqubo zokukhusela umlilo, ekwazi ukumelana noxinzelelo oluphezulu lwamanzi kunye nokuqinisekisa ukuvalwa okuthembekileyo kwimeko yomlilo. Yenziwe ngezinto ezikumgangatho ophezulu kwaye inokumelana ne-corrosion ebalaseleyo kunye namandla omatshini.
2, iiparamitha zobuGcisa
Iiparamitha zobuchwephesha zevalve yesango lokunyuka kwesiqu somlilo esilastiki simi ngolu hlobo lulandelayo:
Idayamitha yeNominal: DN50-600mm
Uxinzelelo lwegama: PN1.6 / 2.5MPa
Ubushushu bokusebenza: ≤ 200 ℃
Uxinzelelo lokutywina: 0.80 ℃
Isixhobo somzimba weValve: intsimbi etyhidiweyo
Imidiya esebenzayo: amanzi acocekileyo, ulwelo olungadlekiyo
3, Imilinganiselo yoqhagamshelwano lwangaphandle oluphambili
Imilinganiselo engundoqo yoqhagamshelo lwangaphandle lwevalve yesango yokunyuka kwesiqu somlilo ilastiki yokutywina ilandelayo:
