The opening force of big valve.The bell top of cap assembly 3 is provided with exhaust hole, can eliminate air gas and block up and steam vapour lock.
Operation principle of the present utility model is such：When Movable-fulcrum lever bucket-type low-pressure steam trap is arranged on
After on pipeline, when low-temperature condensate is by working media water inlet 25, into screen pack 23, now bell cap assembly 3 is in down
The bottom of valve body 1, valve seat 5 are in open position, and low-temperature condensate discharges rapidly, at the same time discharges air.Temperature raises in valve
Afterwards, but in cavity still it is filled with water, valve element 16 is in original state, and condensed water in high temperature continues to discharge.When condensed water in high temperature is fast
When draining, steam is full of the bell inner chamber of cap assembly 3, and filling vapour when the bell inner chamber top of cap assembly 3 highly exceedes needed for dynamic balance state
After filling vapour height, the buoyancy suffered by bell cap assembly 3 is more than gravity, and bell cap assembly 3 accelerates, and drives control cage part 4
Driving valve element 16 moves upwards, valve element 16 the effect of inertia and condensed water in high temperature that are moved upwards at a high speed the absorption affinity of outflow and
In lower valve body 1 in the presence of pressure medium, it can be made above and below hook 6-2 using two circular hole 4-1 of control cage part 4, left and right
Activity, up and down amount is 0~4.8mm, left and right activity is 0~1.5mm.Valve element 16 self-centering, self-closing valve seat
Hole, valve are in closed mode.As the bell inner chamber steam of cap assembly 3 is reduced, condensed water in high temperature increases, and buoyancy is reduced and sunk,
Valve element 16 sinks under the driving of control cage part 4, opens valve seat 5, valve is in huge discharge state, into new circulation work.
