CAST?TRUNNION?BALL?VALVE
1.Blow-out?proof?stem
For?the?purpose?of?preventing?the?stem?from?flying?off??resulting?in?abnormal?rising?of?the?inner?
pressure?of?valve,shoulder?is?fixed?at?the?lower?part?of?the?stem.In?addition,in?order?to?prevent?
leakage?resulting?from?burnout?of?packing?set?of?the?stem?in?a?fire,thrust?bearing?is?set?at?the?
contact?position?of?the?shoulder?at?lower?part?of?the?stem?and?valve?body.Thus?an?inverse?seal?
seat?is?formed?which?will?prevent?leakage?and?avoid?accident.
?
2.Key?lock
Locks?can?be?used?to?lock?the?manual?valve?when??it?is?fully?open?or?closed?so?as?to?prevent?
non-working?personnel?from?pulling?the?handle?which?may?result?in?misoperation?of?valve.It?can?
also?avoid?opening?or?closing?of?valve?resulting?from?the?shock?from?pipelines?or?unpredictable?
factors?that?may?cause?an?accident.For?working?pipelines?such?as?combustible?and?explosive?oil,
gas?and?chemical?medium,or?for?field?piping?site,the?locking?mechanism?is?especially?useful.
?
3.Anti-fire?safe?design
When?the?trunnion?ball?valve?be?used?normally,its?sealed?by?seat?and?ball?surface,seat?retainer?
sealed?by?O-ring?and?body,this?is?soft?sealed?and?reliable?sealing.When?the?seat?and?O-ring?are?
burnt,the?seat?retainer?and?body?will?be?sealed?by?expanded?graphite.Thus?act?anti-fire?safe?purpose.
