Specific embodiment
The present invention is further explained in the light of specific embodiments, but the scope of protection of the present invention is not limited thereto.
Embodiment comparative diagram 1 ~ 4:
A kind of non-return fresh air pipe fitting, including the first fresh air pipeline 1 and the second fresh air pipeline 3, the first fresh air pipeline 1 and second
Fresh air non-return component 2 is provided between fresh air pipeline 3.
Fresh air non-return component 2 include accept tube body 23, positioned at it is described undertaking tube body 23 in inserts circle 22 and with it is described embedding
The non-return baffle 21 that part circle 22 is hingedly arranged, 21 upper end of non-return baffle and 22 top of inserts circle are rotatablely connected in the present embodiment,
It can be using hinge (hinge) the formula connection type (such as Fig. 4) of similar Pivot for door or window connection.In order to reduce fresh air non-return component 2
Overall weight accepts the material selection plastics of tube body 23, and in order to increase the durability of fresh air non-return component 2, non-return baffle 21
With the material selection metal of inserts circle 22, metal is bigger than plastic density and more durable, and there are certain quality, non-return gears for metal
Plate 21 has better non-return effect, such as when closing fresh air pipeline, will not because of small wind-force (air of indoor or outdoors from
So flowing) and lead to waving for non-return baffle 21, cause noise to impact indoor life；Metal is relatively sanitary compared with plastics,
It is not easy the advantages that breeding bacterium, helping to improve the quality of air.
It accepts tube body 23 and uses plastic material, 23 both ends of undertaking tube body are new with the first fresh air pipeline 1 and second respectively
Air piping 3 is fixed with sealing, connection type may is that it is described accept tube body 23 both ends respectively with the first fresh air pipeline 1 and
The corresponding end of second fresh air pipeline 3 is sealedly and fixedly connected by socket joint or is fixedly connected by hot-melting sealed.
It accepts tube body 23 and is equipped with annular groove along inner wall, what the outer edge of inserts circle 22 matched is mounted on the annular groove
It is interior, since there are interfaces with plastics for metal, it will appear crackle using the connection of plastics after a long time, here in inserts circle 22 along outside
Edge is uniformly arranged tooth form convex block, and when inserts circle 22 is installed in plastic pipe main body 23, the tooth form convex block snaps into described
In annular groove, tooth-shape structure is set in 22 outer edge of inserts circle, inserts circle 22 and plastic pipe main body can further be turned up
Degree of fitting closely between 23 prevents under the action of the wind, and metal slides, and causes to grind to 23 inner wall of plastic pipe main body
Damage, cracks.
The inserts circle 22 is equipped with the ventilation hole 220 to divulge information, and the non-return baffle 21 is to cover the ventilation
Hole 220；Ventilation state, the non-return baffle 21 tilt, and first fresh air pipeline 1 and second fresh air pipeline 3 are by leading to
Air holes 220 penetrates through；Non-return state, the covering of non-return baffle 21 are closed to the ventilation hole, first fresh air pipeline 1 and institute
It is mutually isolated to state the second fresh air pipeline 3.In order to have better non-return and ventilation effect, the shape and non-return of the ventilation hole 220
The shape of baffle 21 is adapted, and the area of ventilation hole 220 is slightly less than the area of the non-return baffle 21, in this way in quiet wind or wind
Under power very little, non-return baffle 21 blocks the ventilation hole 220 on inserts circle 22, and pipeline is not easy to leak out, and generates noise.When what is be passed through
When air quantity is larger, so that ventilation hole 220 is kept biggish area as far as possible, (i.e. the area of ventilation hole 220 is slightly less than the non-return baffle
21 area is the maximum area that ventilation hole 220 can be taken in the case where realizing non-return effect), can have biggish logical
Air quantity, 21 lower end of non-return baffle and inserts circle 22 are detached from vacantly, and can be freely swung under the action of the wind, and wind is from ventilation hole
220 pass through.
It is circular pipe due to accepting tube body 23, after non-return baffle 21 swings certain angle under the action of the wind, non-return
Baffle 21 will be stopped by 1 inner wall of fresh air plastic conduit, and the shape of non-return baffle 21 is to its swing angle in circular pipe
Have a great impact.In order to have preferably ventilation and non-return effect, 21 outer periphery of non-return baffle includes arc-shaped edges 21a, heterotype edge
21b and hinge side 21c, the arc-shaped edges 21a are located at the lower part of the non-return baffle 21, and the hinge side 21c is located at described stop
The top for returning baffle 21 is docked between the arc-shaped edges 21a and the hinge side 21c by the heterotype edge 21b.Such as Fig. 4, only
Arc-shaped edges 21a is arranged in the lower part for returning baffle 21, and the width of arc-shaped edges 21a is greater than the width of heterotype edge 21b and hinge side 21c, this
The center of gravity of non-return baffle 21 is set to be located at its lower end, so that non-return baffle 21 is easy to move down close to inserts circle 22, in same weight
Under, there is better windproof effect.Secondly when ventilation quantity it is larger so that non-return baffle 21 tilt when, the circular arc of 21 lower part of non-return baffle
The side both ends 21a are adjacent to circular pipe inner wall, will not be stuck in circular pipe since the end arc-shaped edges 21a is arc-shaped, and will not
Abrasion is generated to the circular pipe of plastics.Comparative diagram 4 can be seen that the shape of ventilation hole 220 is mutually fitted with the shape of non-return baffle 21
Match, and the size of ventilation hole 220 is slightly larger than the size of non-return baffle 21.
The design method of the non-return fresh air pipe fitting non-return baffle, comprising the following steps:
Step S1: according to the ventilation internal diameter D of fresh air pipeline and non-return baffle maximum tilt angle α (in comparative diagram 2
Maximum tilt angle α), determine that the preliminary structure of non-return baffle, the preliminary structure of the non-return baffle include at least non-return baffle
21 maximum outside diameter dimension D ' (in comparative diagram 4, D ' is the maximum distance of the hinge side 21c and arc-shaped edges 21a of non-return baffle 21)
With the arc length L(comparative diagram 3 for the arc-shaped edges 21a for being located at 21 bottom of non-return baffle), wherein D ' is slightly less than D, α/360 L=π D '.
Step S2: when non-return baffle 21 is in maximum opening, the both ends arc-shaped edges 21a position is in and fresh wind tube
Road inner wall is bonded to each other, and determines the heterotype edge 21b structure of non-return baffle 21, the heterotype edge 21b is according to fresh air pipeline inner wall knot
Structure is adjusted, and is bonded the heterotype edge 21b more with the fresh air pipeline inner wall；
Step S3: the hinge side of the non-return baffle 21 is designed according to length needed for 21 hinge point of non-return baffle
Length needed for 21c, the hinge side 21c are greater than 21 hinge point of non-return baffle.
Design by the above method to 21 structure of non-return baffle comprehensively considers the maximum tilt angle α of non-return baffle 21
And maximum area, and a reasonable range is designed, realize maximum ventilation effect.
Content described in this specification is only to enumerate to inventive concept way of realization, and protection scope of the present invention is not answered
When the concrete form for being seen as limited by embodiment and being stated.
