Iivalvu zebhabhathane ezinkulu zihlala zibhekisa kwiivalvu zebhabhathane ezinobubanzi obungaphezulu kwe-DN500, ezihlala ziqhagamshelwe ziiflanges, iiwafers. Kukho iintlobo ezimbini zeevalvu zebhabhathane ezinkulu: ivalvu yebhabhathane engqindilili kunye neevalvu zebhabhathane ezingaqhelekanga.
Ungayikhetha njani ivalvu yebhabhathane enkulu?
1. Xa ubungakanani bevalvu buncinci kune-DN1000, uxinzelelo olusebenzayo lungaphantsi kwe-PN16, kwaye ubushushu bokusebenza bungaphantsi kwe-80℃, sihlala sicebisa ivalvu yebhabhathane yomgca oqinileyo kuba iya kuba yeyonga kakhulu.
2. Ngokwesiqhelo, xa ububanzi bungaphezulu kwe-1000, sicebisa ukusebenzisa ivalvu yebhabhathane engaqhelekanga, ukuze i-torque yevalvu incitshiswe ngempumelelo ngenxa ye-engile engaqhelekanga yevalvu, evumela ukuvulwa nokuvalwa kwevalvu. Ukongeza, ivalvu yebhabhathane engaqhelekanga inokunciphisa okanye isuse ukungqubana phakathi kwepleyiti yevalvu kunye nesihlalo sevalvu ngenxa ye-engile engaqhelekanga, kwaye iphucule ubomi benkonzo yevalvu.
3. Kwangaxeshanye, ukungeniswa kwezihlalo zesinyithi kuphucula ubushushu kunye nokumelana noxinzelelo lweevalvu zebhabhathane kwaye kwandisa uluhlu lokusetyenziswa kweevalvu. Ngoko ke umgca ophakathiivalvu yebhabhathane enobubanzi obukhuluNgokwesiqhelo ingasetyenziswa kuphela kwiimeko eziphantsi koxinzelelo olufana namanzi, ngelixa ivalvu yebhabhathane engaqhelekanga ingasetyenziswa kwiindawo ezineemeko zokusebenza ezinzima ngakumbi.
