The mass of corresponding weight is set, when the air pressure in automatic exhaust pipe reaches preset value, baffle could be jacked up, avoid baffle
Frequent keying.
Further, the automatic exhaust pipe is equipped with elastic balloon.Elastic balloon plays the role of elastic buffer.When
When air pressure in automatic exhaust pipe is not up to the Opening pressure of baffle, a part of gas is stored in elastic balloon；With automatic
Gas in exhaust pipe is on the increase, and gradually expansion becomes larger elastic balloon, and since elastic balloon is there are elastic-restoring force, to certainly
Gas in dynamic exhaust pipe is carried out at the same time a degree of compressing；When the air pressure in automatic exhaust pipe reaches preset value, baffle
Being jacked up, the gas in automatic exhaust pipe is discharged through blow vent, meanwhile, under the elastic-restoring force effect of elastic balloon, elasticity
The gas of inside air bag storage is also constantly discharged, and elastic balloon is gradually restored to the original state.
Further, the Manual air exhausting mechanism includes the manual exhaust pipe being arranged on total air escape pipe and is arranged on
Manual air-release valves on manual exhaust pipe.When needing manual exhaust, Manual air-release valves can be opened, the gas in device is whole
Discharge.
After the utility model is in practical application, air and indirect steam in boiler feed pump pass through millipore filter,
Automatic exhaust pipe, manual exhaust pipe are respectively enterd through total air escape pipe；It is on the increase with the yield of gas, the air pressure in device
Constantly increase, when reaching the Opening pressure of baffle, the gas in device is discharged through blow vent；If desired manual exhaust, can beat
Manual air-release valves are opened, the gas in device is all discharged.
Compared with prior art, the utility model has the characteristics that：
