Description
Technical field
The utility model belongs to underground coal mine Ventilation Control technical field, and in particular to a kind of mining cambered surface pneumatic air door.
Background technology
Existing currently used mine pneumatic air door, such as balances non-pressure damper, biparting OBD.Balance is without pressure wind
Although door need not set reverse throttle, and manufacturing cost is low, economic and practical, and it typically uses flat board door leaf and for built-in edge
Be embedded in the structure in doorframe, once meet with ore deposit compressive strain, air door can not smoothly open and close, cause the recovery of air door function very
It is difficult.Non-pressure damper such as underground blast and the larger situation of air door area, flat board door leaf non-deformability are poor, yielding, lead
Cause can not be closed and cause to leak out.Common OBD, generally only positive air door can realize pneumatic control, reverse throttle hand
It is dynamic normally opened to be difficult to realize pneumatic control.Although part design is employed on top case plus top case structure can realize positive air door with
Reverse throttle Synchronization Control, but its air door structure has a strong impact on lane height road latus rectum size, also has cylinder being placed on door leaf
On, its Synchronization Control can be also realized, but because the physical dimension difference of positive air door and reverse throttle can not be realized greatly very much mutually
Change, can not change supply in time once meeting with air door and damaging, easily cause ventilating system can not in time recover and have a strong impact on logical
Airduct is managed, if the normally closed controlled state of air flow in laneway can not be realized, will bury potential safety hazard to mine ventilation.
This air door not only strengthens air door Wind-Pressure Resistance deformability, door leaf is plug-in effectively to be prevented compared with ordinary flat structure
Only ore deposit compressive strain air door is failed, and air door is hardly damaged and then improves service life, and also repeatable dismounting is used.Ordinary flat
Flat-open type door opening, such as otherwise influence tunnel latus rectum size, door leaf opening angle is just achievable commonly greater than 90 degree, and our
Case opening angle can be met less than 70 degree, and such cylinder enabling stroke reduces cylinder and the position of door leaf pin joint can be as far as possible
Away from the doorframe corresponding to door leaf, the push-pull effort needed for reduction opening and closing door leaf increases the position of opening point and door hinge, just makes door
Fan open and close becomes dexterous laborsaving.Positive air door is identical with reverse throttle physical dimension simultaneously, and symmetrical member can be exchanged temporarily, and
Same specification door leaf and its accessory are generally applicable to be exchanged.The special construction of other this programme, employs Special seal, is sealed in
Concora crush between door leaf and doorframe, in the presence of the blast of tunnel, positive air door is pressed tighter and tighter with doorframe, and air door sealing effectiveness is more
It is good, energy consumption reduction by more than 20%.
