Iivalvu zebhabhathane ezinobungakanani obukhulu zidla ngokubhekisa kwiivalvu zebhabhathane ezinobubanzi obungaphezulu kwe-DN500, ezidla ngokudityaniswa ngeeflange, iiwafers.Kukho iindidi ezimbini zeevalvu zebhabhathane ezinobubanzi obukhulu: ivalve yebhabhathane ephakathi kunye nevalve yebhabhathane eccentric.
Unokukhetha njani ivalve yebhabhathane enkulu?
1. Xa ubukhulu bevalve buncinci kune-DN1000, uxinzelelo lokusebenza lungaphantsi kwe-PN16, kwaye ubushushu bokusebenza bungaphantsi kwe-80 ℃, ngokuqhelekileyo sincoma i-valve ye-butterfly yomgca we-concentric njengoko iya kuba noqoqosho kakhulu.
2. Ngokuqhelekileyo, xa ububanzi bukhulu kune-1000, sincoma ukusebenzisa i-valve ye-butterfly eccentric, ukwenzela ukuba i-torque yevalve inokunciphisa ngokufanelekileyo ngenxa ye-angle eccentric yevalve, ehambelana nokuvulwa nokuvalwa kwevalve. ivalve.Ukongeza, i-valve ye-butterfly eccentric inokunciphisa okanye isuse ingxabano phakathi kwepleyiti yevalve kunye nesihlalo sevalve ngenxa ye-angle eccentric, kunye nokuphucula ubomi benkonzo yevalve.
3. Ngelo xesha, ukungeniswa kwezihlalo zetsimbi kuphucula ubushushu kunye nokunyanzeliswa koxinzelelo lweevalve zebhabhathane kunye nokwandisa uluhlu lwezicelo zeevalve.Ke ivalve yebhabhathane enobubanzi obuphakathi idla ngokusetyenziswa kuphela kwiimeko ezinoxinzelelo oluphantsi njengamanzi, ngelixa ivalve yebhabhathane eccentric ingasetyenziswa kwindawo ezineemeko zokusebenza ezinzima.
