32, sealing ring 31 can be arranged in sealing ring framework 32.Sealing ring framework 32 can circumferentially surround downtake pipe 1 with
The intersection of second exhaust pipe 2, sealing ring framework 32 can limit the accommodating chamber of annular, and sealing ring 31 can be by sealing ring bone
Frame 32 is contained in accommodating chamber, in order to strengthen sealing of the sealing ring 31 to downtake pipe 1 and the intersection of second exhaust pipe 2
Performance.
Specifically, sealing ring 31 can be carbon seal ring, because the gas in the blast pipe 100 in blast pipe 100 is
Vehicle motor burning after produce, therefore vehicle traveling in blast pipe 100 temperature it is higher, and carbon seal ring have it is good
Heat-resisting quantity, so that sealing ring 31 can still ensure the boundary to downtake pipe 1 and second exhaust pipe 2 at relatively high temperatures
The sealing at place, prevents gas in blast pipe 100 from downtake pipe 1 and the gap leakage of the intersection of second exhaust pipe 2.
Specifically, as shown in figure 1, sealing ring framework 32 can coat the outer surface of sealing ring 31, that is, ring framework 32 is sealed
Can be fitted tightly over outside sealing ring 31, so as to sealing ring 31 is fixedly secured in downtake pipe 1 and second exhaust pipe 2
Intersection, enhancing sealing ring 31 is to downtake pipe 1 and the sealing property of the intersection of second exhaust pipe 2.
In some specific embodiments, as shown in figure 1, end flanges can be provided with the end face of the second inserted terminal 21
211, end flanges 211 can peripherally and outwardly be protruded along the end face of the second inserted terminal 21, and sealing ring 31 can be set in first row
On the outer peripheral face of tracheae 1 and only to end flanges 211, more specifically, sealing ring 31 can only be against the side of end flanges 211
Wall, and end flanges 211 and sealing ring 31 can be contained in the sealing accommodating chamber that limits out of ring framework 32, so as to strengthen close
Seal 31 is to downtake pipe 1 and the sealing property of the intersection of second exhaust pipe 2.
In some more specific embodiments, as shown in figure 1, sealing ring framework 32 can include pressing plate portion 321 and grand
Play portion 322, protrusion 322 can in the pressing plate portion 321 all protruding upward of downtake pipe 1 and the intersection of second exhaust pipe 2,
The accommodating chamber of annular can be limited in protrusion 322.
As shown in figure 1, sealing ring 31 can include body 311 and lug boss 312, body 311 can be set in the
On the outer peripheral face of one blast pipe 1, body 311 can be pressed on downtake pipe 1 by pressing plate portion 321 in the outside of body 311
Outer peripheral face on, lug boss 312 can be in the body all protruding upward of downtake pipe 1 and the intersection of second exhaust pipe 2
311, i.e. lug boss 312 can be more than body 311 in downtake pipe 1 and the thickness radially of second exhaust pipe 2.
As shown in figure 1, lug boss 312 can only support end flanges 211, lug boss 312 and end flanges 211 can be received
It is contained in the accommodating chamber of protrusion 322, lug boss 312 can strengthen sealing of the sealing ring 31 at end flanges 211.
Specifically, as shown in figure 1, downtake pipe 1 may be located at the upper of second exhaust pipe 2 on the flow direction of exhaust
Trip side, in other words, during the gas in blast pipe 100 can flow to second exhaust pipe 2, i.e. blast pipe 100 from downtake pipe 1
Gas flow direction can along Fig. 1 direction shown in arrow.Thus, it is possible to prevent the gas in blast pipe 100 along the first grafting
Gap leakage of the periphery wall at end 11 between the first inserted terminal 11 and the second inserted terminal 21.
