Abstract
The invention relates to a sealing device, in particular to an air door sealing device. The air door sealing device comprises an air door and a shaft, wherein the shaft is inserted into the air door, a quick connector is arranged on an outer wall of the shaft at one side of the air door, a seal washer is arranged between the quick connector and the shaft, and a glass reinforced plastics cladding layer is arranged at a connection part between the quick connector and the air door. The air door sealing device has simple structure and good airtight effect, thus achieving the purpose of avoiding air leakage.
Description
Technical field
The present invention relates to a kind of seal arrangement, relate in particular to the seal arrangement of air door.
Background technique
Utilizing air door to regulate pipeline air quantity open and close pipeline on exhaust duct, is a very general technology.At present, more commonly drive axle and rotate, thereby make the blade deflection on the axle realize the opening and closing air door by rotating handles.But axle often has certain slit when passing the air door body, so just has the phenomenon of gas leakage, and the air-tightness of air door is not ideal enough.Waste gas can be leaked to the outside by the slit, befouling environment simultaneously.
Summary of the invention
The object of the invention provides a kind of simple in structure, and airtight effect is good, avoids the air door seal arrangement of gas leak phenomenon.
A kind of air door seal arrangement comprises air door, axle, and axle is set on the air door, and the outer wall that is positioned at the axle of air door one side is provided with rapid pipe joint, between rapid pipe joint and the axle seal washer is set.
The joint of rapid pipe joint of the present invention and air door is provided with the glass fibre reinforced plastics clad.
The present invention adopts technique scheme, compared with prior art have following advantage: the present invention utilizes the elastic packing packing ring in the rapid pipe joint to fit tightly the sealing that realizes air door with axle, this apparatus structure is simple, flexible and convenient to use, not only can significantly improve the sealability of air door, prevent gas leakage, befouling environment and make the axle rotary course more stable.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is a user mode schematic representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing technological scheme of the present invention is elaborated:
As shown in Figure 1 and Figure 2, a kind of air door seal arrangement comprises air door 1, axle 5, and axle 5 is set on the air door 1, and the outer wall that is positioned at the axle 5 of air door 1 one sides is provided with rapid pipe joint 2, between rapid pipe joint 2 and the axle 5 seal washer 3 is set.
The present invention includes the rapid pipe joint 2 that is located at axle 5 and passes air door 1 body place, be positioned at a rapid pipe joint 2 and 5 seal washer that fit tightly 3; Rapid pipe joint 2 coats face 4 with air door 1 joint by glass fibre reinforced plastics and fixes.During rotating handles 6, the axle 5 of fitting with seal washer 3 rotates, thereby is installed in the blade deflection opening and closing air door 1 on the axle 5.
The present invention utilizes the elastic packing packing ring 3 in the rapid pipe joint 2 to fit tightly the sealing that realizes air door with axle 5, this apparatus structure is simple, and is flexible and convenient to use, not only can significantly improve the sealability of air door, prevent gas leakage, and make the rotary course of axle more stable.
Claims (2)
