During running of heating system and HVAC system
,£¬the releasable gas (like hydrogen ,oxygen) will bring
much blights damage system and reducer the low-heating effect
when the water is heating , if the gas can't discharge will cause
much blights. Such as :oxidize lead to rusty ; gaseous will be
formed in radiator ; hot-water circulation will be block and imbalance,
make radiator some parts not hot; make noise when pipeline running
with gas£»£»the vortex air phenomenon
of recycle pump. This shows the important function use automatic
exhaust steam valves.
The design of new type automatic exhaust steam valve consider
all known adverse factors,(like impurity, oil, suspended matter
in the water ;liquid in valve cause upheaval when exhausting ;vibration
of pipeline and equipment connected exhaust valve.) Have excellent
function: whether start running with water in system(the large
gas will discharge when system start running) or moderately drain
and pressure relief when the system hypertension, all can reliability
service.
1),Feature:
1£®Dependable performance . The exhaust mechanism of
exhaust valves very reliable, every valve all pass the exhaust
experiment and pressure sealing experiment before leave factory.
Single component cast with high precision, thus get to prefect
assemble.
2£®Convenient maintenance. Automatic exhaust steam valve
have blockade valve, block valve allow unload exhaust valve conveniently
from system to maintain, and the water in system can't flow, so
needn't evacuate system.
3£®Only exhaust, not drain. Gas, water division design
adopt to special structure, guarantee not drain when exhaust.
4£®If only the system have pressure
, exhaust valve will continuous exhaust .
2),main application:
Automatic exhaust steam valve use: stand alone heating system;
district heating system ; floor radiant heating system; solar
heating system; heat pump system;£»central air conditioner£»heating
boiler etc.
3),operating principle of automatic exhaust steam valve
When system have air, gas gather at top of exhaust valve, internal
bubble accumulate make float ball with water levels fall, so open
the exhaust piston, after gas exhaustion; water level up, float
ball also up with water ,close the exhaust piton. If screw down
lateral bonnet of valve, exhaust valve stop exhaust, in general
,bonnet should being on-state.
