Description
Technical field
The present invention relates to a kind of motor vehicle flame arrester, particularly a kind of flame trap that can adapt to different outlet pipe calibers.
Background technique:
When motor vehicle enter inflammable and explosive region, in order to prevent that fire from need to install flame trap on outlet pipe.Common way is to select the flame trap of different model according to different motor vehicle exhaust caliber size.Require to be equipped with like this flame trap of various interface caliber, very uneconomical, management, operation are also inconvenient.Chinese patent ZL200920066667.6 discloses a kind of adjustable automobile fireproof shade.This adjustable automobile fireproof shade, by adjusting bolt clamp, is fixed on flameproof enclosure on the outlet pipe of different tube diameters.This mode, has solved and can not adapt to the problem of different tube diameters, but exists interface blow-by, may have Mars and emerge from jointing, still has potential safety hazard.In addition, because automobile exhaust cylinder is positioned at vehicle body below, particularly lorry, installs at the bottom of needing installation personnel to pierce car when installation, very inconvenient, and installation personnel is easily deflated cylinder and scalds.
Summary of the invention:
Motor vehicle flame arrester of the present invention overcomes existing flame trap sealing joint but is unadjustable, or adjustable but packing less defect, has reached flame trap not only salable but also adjustable, simultaneously convenient effect of installing.
A kind of motor vehicle flame arrester, comprise back-fire relief body, with the affixed back-fire relief body connecting cylinder of back-fire relief body entrance, back-fire relief body connecting cylinder is fixed to the clamp device on motor vehicle exhaust, it is characterized in that: also comprise a ring set and 12 above long strip elastic sealing strips; Described ring set can be inserted on motor vehicle exhaust, and ring set and back-fire relief body connecting cylinder are threaded connection; Described elastic sealing strip overlaps successively and uniform ring is distributed in the inner ring of described ring set, and elastic sealing strip one end is fixed on described ring set, and the other end is the free end that tiltedly points to axle, and free end is close on motor vehicle exhaust by self spring energy.Like this, the flame trap of same interface accesses the outlet pipe of different tube diameters, also can obtain the effect of good back-fire relief.
In order to strengthen the elasticity of elastic sealing strip, strengthen sealing reliability, elastic sealing strip outside is provided with annular extension spring.
Increase the quantity of elastic sealing strip as 24 or 36 etc., can improve sealing effect.
The clamp device that flame trap is fixed to motor vehicle exhaust funnel comprises the clamp, guide rod and the folder of the round mouth with handle that are arranged symmetrically with; The hinges fixing of described round mouth folder fixes on described back-fire relief body connecting cylinder, and round mouth folder handle end is provided with bolt on one side, another side correspondence has hole; Described guide rod one end is radially connected to that round mouth folder is upper and the other end passes freely through back-fire relief body connecting cylinder and be fixed with described clamp.
For ease of installing, dismantling, according to motor vehicle exhaust mounting point difference, back-fire relief body connecting cylinder is made U-shaped shape, and wherein U-shaped intermediate section length is 0.5～1.5m, and round mouth folder decreased food also should be 0.5～1.5m mutually.Like this, can get into the face installation and removal of car inside story for part lorry.

Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1: a kind of motor vehicle flame arrester, comprise back-fire relief body 8, with the affixed back-fire relief body connecting cylinder 7 of back-fire relief body 8 entrances, the clamp device that back-fire relief body connecting cylinder 7 is fixed on motor vehicle exhaust 1.It is characterized in that: also comprise 2 and 12 above long strip elastic sealing strips 3 of a ring set; Described ring set 2 can be inserted on motor vehicle exhaust 1, and ring set 2 is threaded connection with back-fire relief body connecting cylinder 7; Described elastic sealing strip 3 overlaps successively and uniform ring is distributed in the inner ring of described ring set 2, and elastic sealing strip 3 one end are fixed on described ring set 2, and the other end is the free end that tiltedly points to axle.Free end is close on motor vehicle exhaust 1 by self elastic force.
When installation, flame trap of the present invention is directly inserted in to motor vehicle exhaust 1 certain length.In the time accessing the outlet pipe 1 of different tube diameters, move clamp 6 by adjusting screw rod 5, flame trap is clamped on outlet pipe 1.The free end of elastic sealing strip is adjacent on outlet pipe 1 outer surface, prevents that the Mars that motor is discharged from flying out from jointing.
In order to strengthen the elasticity of elastic sealing strip, strengthen sealing reliability, be provided with annular extension spring 4(as Fig. 2 in elastic sealing strip 3 outsides).
As shown in Figure 3, described clamp device comprises: two clamps that are arranged symmetrically with 6 and guide rod 12, and round mouth folder 11 with handle.The hinge 10 of round mouth folder 11 is fixed on back-fire relief body connecting cylinder 7, and round mouth tong handle 13 ends are provided with bolt 15 on one side, another side correspondence has hole 14.Described guide rod 12 one end are radially connected on round mouth folder 11 and the other end passes freely through back-fire relief body connecting cylinder 7 fixing described clamp 6.When use, open round mouth tong handle, the appropriate location that ring set 2 and back-fire relief body connecting cylinder 7 are inserted in to the outlet pipe 1 of Motor Vehicle, the handle 13 that closes, bolt 15 is through hole 14, tightens up with nut, flame trap can be fixed on Motor Vehicle.
