Abstract
The utility model discloses an automatic quick-opening air door, which comprises an air door frame, an air door plate and an electromagnetic reversing valve. The air door plate is connected with the air door frame in a sealed manner; an air pressure rod is arranged at the center of one side of the air door plate that is not adjacent to the air door frame; both ends of the air door plate are welded with lining boards; the air door frame is provided with a guide rail; the tail end of the guide rail is provided with a connecting frame; the tail end of the air pressure rod is connected with a pneumatic cylinder arranged on the connecting frame; the lining boards are provided with idler wheels and arranged on the guide rail of the air door frame; and the pneumatic cylinder is connected with the electromagnetic reversing valve. The automatic quick-opening air door has the advantages of reliable quality, large air supply area and strong seal performance, and is easy to open.
Description
Technical field
The utility model relates to a kind of air door that is used for controlling the air quantity size, relates in particular to a kind of door that blows in soon automatically that has hydraulic actuator.
Background technology
The door that blows in soon is mainly used on the air channel of oil plant heating furnace, and it mainly acts on is to break down at the heating furnace air blast, in time opens when burning can not be provided with wind, relies on combustion chamber draft to suck air naturally to keep heating furnace burning wind.Be when guaranteeing blower fault, the capital equipment of heating furnace burning air feed; And an existing limitation owing to mechanism design of blowing in soon, it is little to exist open area, can not provide sufficient burning to use wind, poorly sealed, and dwang is yielding, after the distortion, the stubborn drawback of air door.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of reliable in quality is provided, and air supply areas is big, and sealing is strong, easily the door of opening that blows in soon automatically.
Automatically the door that blows in soon of the present utility model comprises: air door and air door plate and solenoid directional control valve.Be the sealing shape between air door plate and air door and be connected, its not adjacent with air door one side centre position is provided with atmospheric pressure pole, and two ends are welded with liner plate.Described air door is provided with guide rail, and the end of guide rail is provided with link.
The aforesaid door that blows in soon automatically is characterized in that: the end of described atmospheric pressure pole is connected with pneumatic cylinder on being installed in link.
The aforesaid door that blows in soon automatically, it is characterized in that: described liner plate is provided with roller, and places on the guide rail of air door.
The aforesaid door that blows in soon automatically, it is characterized in that: described pneumatic cylinder is connected with solenoid directional control valve.
The advantage good effect:
1, become the drawer type opening ways from original gate-type opening ways, the incoming air area identical at aperture area increases by 1 times, and can be by opening the length adjustment wind supply quantity;
2, the gate-type rubber seal is adopted on four limits, does not leak out substantially after the closure;
3, adopt guide tracked pulley structure, do not have dwang, no jam phenomenon in the switching process guarantees practical safe and reliable.
Description of drawings
Fig. 1 is design principle figure of the present utility model
Fig. 2 is a structural representation of the present utility model
The specific embodiment
, be further described the utility model below in conjunction with description of drawings.
Fig. 1～Fig. 2 is a preferred version of the present utility model: shown: air door 1 and air door plate 2 and solenoid directional control valve 3.Air door plate 2 is the sealing shape with 1 of air door and is connected, and its not adjacent with air door one side centre position is provided with atmospheric pressure pole 4, and two ends are welded with liner plate 5.Described air door 1 is provided with guide rail 6, and the end of guide rail 6 is provided with link 7.
The aforesaid door that blows in soon automatically is characterized in that: the end of described atmospheric pressure pole 4 is connected with pneumatic cylinder 8 on being installed in link 7.
The aforesaid door that blows in soon automatically, it is characterized in that: described liner plate 5 is provided with roller 9, and places on the guide rail 6 of air door 1.
The aforesaid door that blows in soon automatically, it is characterized in that: described pneumatic cylinder 8 is connected with solenoid directional control valve 3.
Operation principle:
When solenoid directional control valve 3 outages, reset under solenoid directional control valve 3 effect of portion's spring within it, compressed air arrives pneumatic cylinder 8 epicoeles through solenoid directional control valve 3 commutations, promote cylinder piston and drive atmospheric pressure pole 4 to move downward, drive air door plate 2 air door is opened, because the two ends of air door plate 2 are welded with liner plate 5, it is provided with roller 9, roller 9 slides along guide rail 6 in the whole process, and resistance is very little, so easily open fast.Otherwise be that air door plate 2 closes closed procedure.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, but every technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
