Description
Technical field
The present invention relates to a kind of safety door, more particularly to a kind of air channel safety door.
Background technology
It is well known that there is negative pressure inside the smoke duct of thermal power plant always, when negative pressure value is in design negative pressure value scope
When interior, airduct can be adjusted voluntarily；But when negative pressure value exceedes design pressure value, air channel needs to carry out automatic ventilation blood pressure lowering,
It is no and will affect whole system safety.The complex environment being additionally, since in smoke duct, high temperature, high pressure, various chemical elements
Deng, general electronic induction valve is difficult to be worked in such environment, therefore in order to long-time is used under complex environment,
Preferably being driven using mechanization completely for safety door, even if taking reaction according to physical change, reduces internal medium to equipment unit
The impact of device, extends the service life of safety door.
The content of the invention
The present invention is directed to deficiency of the prior art, there is provided a kind of boiler energy-saving new type of safe self-con-tained unit, can pass through

Slide on described spacing slideway and be provided with positioning rotating shaft, described positioning slide is connected with described positioning rotating shaft, described
Positioning slide bottom is provided with balancing weight, and several negative pressure valves are provided with described sealing frame, and described negative pressure valve exists
Automatically turn on during negative pressure in wind passage mouth.
In above-mentioned technical proposal, it is preferred that under restriction of the positioning rotating shaft in the skidding distance of the spacing slideway
The resupinate angle of described safety door is between 0 degree to 45 degree.
In above-mentioned technical proposal, it is preferred that described safety door is connected with trip shaft.
In above-mentioned technical proposal, it is preferred that described sealing inframe is provided with placing trough, described negative pressure valve is arranged on
In described placing trough, described negative pressure valve includes runner pipe, and check ring is provided with described runner pipe, and described puts
Put and be provided with groove spacing back-up ring, between described check ring and described spacing back-up ring spring, described negative pressure are provided with
Valve one end is in described wind passage mouth and this end is provided with gas outlet, and the other end is outer in described wind passage mouth and this end is provided with
Air intake, in normal state described gas outlet seal be hidden in described placing trough, when in described wind passage mouth in negative
The gas outlet is protruded in described wind passage mouth during pressure.
In above-mentioned technical proposal, it is preferred that the one end of described negative pressure valve in described wind passage mouth is provided with and institute
State the closure that sealing frame is engaged.
In above-mentioned technical proposal, it is preferred that seal convexity is provided with the safety door, is provided with described sealing frame
The sealed groove being engaged with the seal convexity.
The present invention is a kind of safety auto-controlled device of safety door for boiler exhaust gas, and this device does not have any electronics unit device
Part, safety door is realized by frame for movement automatically turns on closing and the regulation of the negative pressure in wind passage mouth.Under original state, peace
Air cock compression seal frame, intercepts the circulation inside and outside wind passage mouth, if now the negative pressure in wind passage mouth exceeds preset value, in air channel
Negative pressure valve starts in the presence of negative pressure in mouthful, allows wind passage mouth inner air and outer air to circulate and causes the pressure recovery in wind passage mouth normal,
Negative pressure valve can be automatically switched off after pressure is normal in wind passage mouth.When using in wind passage mouth, the flue gas in wind passage mouth can jack-up
Safety door is normally discharged, and safety door is maximum in the presence of positioning slide only to open up into 45 degree so that flue gas presses certain stream
Amount is discharged, it is to avoid the excessive loss caused to other equipment of flue gas flow, the drained rear safety door of flue gas also can be in positioning slide
The lower reply of effect reseals sealing frame.Whole process directly relies on wind passage mouth negative pressure and cigarette without the need for the access of electronic component
The pressure of gas carries out the running of various machineries.
Compared with prior art, the invention has the beneficial effects as follows：Open and close valve plate can be opened by gravity principle, not had
The electronic systems such as electronic induction, signal transmission, safe and reliable, easy maintenance, it is lossless, need not manually operate, greatly save
Maintenance cost improves safety operation performance simultaneously.Suitable for complex environments such as the high oil smoke of High Temperature High Pressure in smoke duct.
