Abstract
An open type seal door applies a concave and convex clutched door and doorframe seal structure, concave spring plates made of thin steel boards are designed at the edge of the doorframe, convex seal blocks set at the corresponding places at the door edge and a fireproof coating is coated inside of the door, when the door is closed, a convex seal block and concave seal spring plate are clutched tightly so realizing the seal with simple structure, convenient close and opan and elimianting gap between the door and doorframe effectively, reducing loss of heat energy of boiler smoke exhaust to increase boiler thermal efficiency.
Description
Technical field:
The present invention relates to a kind of open-type metal hermatic door, is a kind of metal hermatic door that is arranged on boiler body or its cigarette air channel, belongs to the boiler Thermal Power Engineering Field.
Background technology:
In order to satisfy the needs of the normal operation of boiler safety, people are standing on boiler body and cigarette air channel thereof to put various open-type metal aperture of doors, as peephole, peep hole, manhole, beat Jiao Kong etc., is convenient to operation, control and the maintenance of boiler operatiopn.When existing boiler aperture of door is closed, only depend on the non-plane contact closely of a periphery and doorframe, have the gap, lack good sealing, cause the boiler exhaust gas loss to increase.Because sky (cigarette) draught head in the outside has tens to hundreds of Pa in the boiler wall, sky (cigarette) draught head in the outside has tens to several thousand Pa in the cigarette wind path wall, therefore, unsealed open-type metallic door is set on boiler body and cigarette air channel thereof, door is difficult to avoid becoming the source of leaking out with the interplanar slit of doorframe, heat energy loss in the boiler is increased on foot, not only waste valuable natural resources, and seriously reduced boiler thermal output.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, a kind of open-type metal hermatic door of new structure is provided, it is convenient that it is opened, and good airproof performance can effectively reduce heat energy loss, improves boiler thermal output.
For realizing such purpose, in the technical scheme of the present invention, adopted concavo-convex door and the doorframe hermetically-sealed construction that interlocks, the periphery of doorframe is provided with the dented spring leaf made from sheet metal, the peripheral correspondence position of door is provided with the male seal piece, spring leaf has certain intensity and elasticity, can closely contact with sealing block, and be convenient to the opening and closing of door.Because the inboard of door must be in the face of furnace high-temperature, therefore the inner surface at door lays the fireproof coating layer.
When door was closed, the male seal piece of door and concavo-convex the interlocking of dented spring leaf of doorframe tightly sealed whole aperture of door, eliminated the gap, effectively stoped boiler to leak out.The inner surface of door lays the fireproof coating layer, can tolerate furnace high-temperature, and can protect Packing spring sheet, sealing block indeformable, makes it can normal for a long time steady operation, reduces the leakage loss of heat energy in the boiler.
The present invention is simple in structure, can effectively eliminate the door and the gap of doorframe when closing, and opens and closes all easily, helps the boiler safety operation and moves, and can effectively reduce the heat-energy losses of boiler exhaust gas, energy savings, raising boiler thermal output.
Description of drawings:
Fig. 1 is the structural representation of open-type metal hermatic door of the present invention.
As shown in Figure 1, hermatic door of the present invention comprises door 1, Packing spring sheet 2, doorframe 3, sealing block 4, the inboard fireproof coating layer 5 of door.
The specific embodiment:
Below in conjunction with accompanying drawing technical scheme of the present invention is further described.
As shown in Figure 1, the present invention has adopted door and the concavo-convex hermetically-sealed construction that interlocks of doorframe, and door 1 can be conventional hinge with doorframe 3 and is connected, and the periphery of doorframe 3 is provided with the spill Packing spring sheet made from sheet metal 2, the periphery of door 1 is provided with male seal piece 4, and the inner surface of door 1 lays fireproof coating layer 5.
When door 1 is closed, the spill Packing spring sheet 2 that the male seal piece 4 and doorframe 3 peripheries of the periphery setting of door are provided with, concavo-convex interlocking, closely pressing reaches sealing effectiveness.The inner surface of door 1 applies and puts fireproof coating layer 5, can tolerate furnace high-temperature.
Claims (1)
1, a kind of open-type metal hermatic door, comprise door (1) and doorframe (3), door (1) and the concavo-convex hermetically-sealed construction that interlocks of doorframe (3) have been it is characterized in that adopting, the periphery of doorframe (3) is provided with spill Packing spring sheet (2), the peripheral correspondence of door (1) is provided with male seal piece (4), and the inner surface of door (1) lays fireproof coating layer (5).
