5. urea tube according to claim 4, it is characterised in that：The prominent length of the 1st joint portion (130a) can be than the 2nd
The cup depth of joint portion (130b) is big, and the prominent length of the 4th joint portion (110b) can be than the depression of the 3rd joint portion (110a)
Depth is small, and so, four combinations portion mutually plugs together, to ensure that transfer tube (130) and ascending pipe (110) interfix.
6. urea tube according to claim 5, it is characterised in that：It is provided with extensible on flange body (171) upper surface
To internal multiple supports hole (171a) of flange body (171), it is provided with table below blind flange (173) and multiple support hole
(171a) corresponding multiple support pins (173a)；Connecting elements (175) is inserted into the 1st connection formed in flange body (171)
In the 2nd connection hole (H2) on hole (H1) and the blind flange (173) corresponding with the 1st connection hole (H1), make flange body (171)
Mutually it is adjacent to blind flange (173) and is connected.
7. urea tube according to claim 6, it is characterised in that：Gas guide part (190) one end and transfer tube (130)
Side connects, and the other end is connected with urea tracheae (500).
8. a kind of installation method of the urea tube as any one of claim 1-7, in the outside portion of transfer tube (130) and urine
Plain path transfers insertion magnetic (150) (S100) in the insertion section (131) set between stream (T) outside；Now, magnetic
(150) it is placed in supporting zone (131a), the open area of the upper end relative to insertion section (131) of magnetic (150)
(131b) is in the state exposed to outside, now, packing component (S) is placed in insertion section (131) (S200)；Packing component
(S) installed in the upside of magnetic (150), so that magnetic (150) is encapsulated, one end and the magnetic (150) of ascending pipe (110)
The open area of the transfer tube (130) of insertion is connected with each other (S300)；In order to ensure transfer tube (130) the 1st, the 2nd joint portion
3rd, the 4th joint portion (110a) of (130a), (130b) and ascending pipe (110), (110b) mutually correspondence connection, while making insertion
The magnetic (150) of insertion makes transfer stream (T) locking in portion (131), now makes ascending pipe (110) with transfer tube (130) phase
Mutual thermal (S400)；Finally, flange body (171) is combined (S500) with blind flange (173), specifically, configure in method
Support pin (173a) on orchid lid (173) is inserted in the support hole (171a) formed in flange body (171), so that flange sheet
Body (171) be combined with each other with blind flange (173), also, in order to ensure connecting elements (175) mutually correspondence insertion is located at flange sheet
1st connection hole (H1) of body (171) and the 2nd connection hole (H2) of blind flange (173), so that flange body (171) and flange
The bonding strength for covering (173) increases.
