It is defined, then it need not be further discussed in subsequent accompanying drawing in individual accompanying drawing.
Fig. 1 is the front view of one embodiment of appendix of the present invention.As shown in figure 1, the appendix of the embodiment of the present invention
Including：Bending tube section 100, bending tube section 100 have first port 110, second port 120 and positioned at first ports 110 and the
Turning 130 between Two-port netwerk 120, bending tube section 100 prolong in the first direction in first port 110 between turning 130
Stretch, bent at turning 130 from first direction to the second direction vertical with first direction, wherein, the outer arc of bending tube section 100
Face S1 is parallel with first direction between first port 110 arrives turning 130, and bending tube section 100 is from first port 110 to turning
The height H of the gas channel at place 130 in a second direction is gradually reduced, as shown in figure 1, first direction is, for example, the X side in Fig. 1
To second direction is, for example, the Y-direction in Fig. 1.
The appendix that the present embodiment provides, the port 110 of one end of the bending tube section 100 by making appendix and appendix
Bending tube section 100 turning 130 between extrados S1 it is parallel with the bearing of trend of pipe, make the bending tube section of appendix
The 100 intrados S2 between port 110 and turning 130 is gradually close to extrados S1, utilizes the bending for changing appendix
Height H of gas channel of the pipeline section 100 from port 110 to turning 130 on the bending direction at turning 130, realize from
The gradual transition at the turning 130 of the bending tube section 100 of appendix is arrived in the port 110 of one end of the bending tube section 100 of appendix,
So as to avoid the suddenly change of gas gas flow direction in pipe when by the bending tube section 100 of appendix, and then reduce
The flow losses of gas and pressure drop in pipe.
Fig. 2 is the top view of another embodiment of appendix of the present invention.Wherein, in Fig. 2 appendix embodiment and Fig. 1
The difference of the embodiment of middle appendix is：Appendix bending tube section 100 from first port 110 to turning 130
Gas channel height H in a second direction while be gradually reduced, make the bending tube section 100 of appendix from first port
The width W of 110 to the gas channel at turning 130 gradually increases to both sides.The appendix that the present embodiment provides, by gas transmission
Height H of gas channel of the bending tube section 100 of pipe from port 110 to turning 130 on bending direction is gradually reduced same
When, the width W of gas channel of the bending tube section 100 of appendix from port 110 to turning 130 is gradually increased, can make
The flow area of the bending tube section 100 of appendix does not change a lot from first port 110 to turning 130, so as to protect
The steady of the flow and flow rate of the gas of the bending tube section 100 by appendix is demonstrate,proved.
In one embodiment, the gas channel of the bending tube section 100 of appendix at turning 130 close to first port
The height of 110 that one end be bending tube section 100 gas channel first port 110 height 1/4 to 2/3, swan-neck
The gas channel of section 100 leads in the air-flow that width of the turning 130 close to that one end of first port 110 is bending tube section 100
1 to 4 times of width in first port 110 of road.
It should be noted that in the present embodiment, the gas channel of the bending tube section 100 of appendix leans at turning 130
The height of that one end of nearly first port 110 and the gas channel of bending tube section 100 the height of first port 110 relation,
And width and bending tube section of the gas channel of bending tube section 100 at turning 130 close to that one end of first port 110
100 gas channel is not limited to relation of plane in the relation of the width of first port 110.Those skilled in the art should
Understand, the gas channel of the bending tube section 100 of the appendix for meeting the present embodiment requirement is at turning 130 close to first end
Mouthfuls 110 height of that one end and the gas channel of bending tube section 100 are in the height of first port 110, and bending tube section 100
Gas channel at turning 130 close to the width of that one end of first port 110 and the gas channel of bending tube section 100 the
Other relations that the width of Single port 110 meets are both contained in the present embodiment.
In the present embodiment, the chi of the size of the second port 120 of the bending tube section 100 of appendix and first port 110
It is very little identical, and bending tube section 100 from turning 130 close to that one end of first port 110 to 120 round and smooth mistake of second port
Cross.Further, the bending tube section 100 of appendix is from first port 110 to the rounding off of second port 120.The present invention is implemented
The appendix that example provides, by making bending tube section 100 streamlined from first port 101 to the rounding off of second port 102, use
Structure, bending tube section 100 of the gas smoothly by appendix can be made, in bending tube section 100 of the gas by appendix
It will not be avoided due to this local resistance and caused flow losses, further reduce by any local resistance
The flow losses of gas and pressure drop in pipe.
It should be noted that in an embodiment of the present invention, the bending tube section 100 of appendix is from second port 120 to turning
The length of crook 130 is less than the bending tube section 100 of appendix from first port 110 to the length at turning 130, but of the invention
Embodiment be specifically limited not to this, in other embodiments of the invention, the bending tube section 100 of appendix is from second port
120 length to turning 130 can be equal to the bending tube section 100 of appendix from first port 110 to the length at turning 130
Degree, or the bending tube section 100 of appendix can also be more than the curved of appendix from second port 120 to the length at turning 130
Curved tube section 100 is from first port 110 to the length at turning 130.As long as it will be understood by those skilled in the art that meet gas transmission
The port of the extrados of the bending tube section of pipe at one end to parallel with the bearing of trend of pipe between turning, and bending tube section from
The appendix that the height of the gas channel on the bending direction at turning at the port at the end to turning is gradually reduced includes
In embodiments of the invention.
Further, the first port 110 of the bending tube section 100 of appendix and second port 120 are circle.The present invention
The appendix that embodiment provides, it is circle by making first port 110 and the second port 120 of bending tube section 100, Ke Yifang
