Description
Technical field
The utility model 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:
Motor vehicle enter inflammable and explosive when regional, need to flame trap be installed at outlet pipe in order to prevent fire.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 is fixed on flameproof enclosure on the outlet pipe of different tube diameters by the adjusting bolt clamp.This mode has solved and can not adapt to the problem of different tube diameters, but exists the interface blow-by, may have Mars and emerge from jointing, still has potential safety hazard.In addition, because the automobile exhaust cylinder is positioned at vehicle body below, particularly lorry, install at the bottom of needing installation personnel to pierce car during installation, very inconvenient, and also installation personnel easily is deflated cylinder and scalds.
Summary of the invention:
Motor vehicle flame arrester described in the utility model overcomes existing flame trap sealing joint but is unadjustable, maybe can regulate but packing less defective, has reached flame trap not only salable but also can regulate, simultaneously convenient effect of installing.
A kind of motor vehicle flame arrester, comprise the 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 clamp device on the motor vehicle exhaust, it is characterized in that: also comprise a ring set and the long strip elastic sealing strip more than 12; Described ring set can be inserted on the 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 the described ring set, and the other end be the oblique free end of sensing axle, and free end is close on the motor vehicle exhaust by self spring energy.Like this, the outlet pipe of the flame trap of same interface access different tube diameters also can obtain the preferably effect of back-fire relief.
In order to strengthen the elasticity of elastic sealing strip, strengthen sealing reliability, the elastic sealing strip outside is provided with annular extension spring.
The quantity that increases elastic sealing strip can improve sealing effect such as 24 or 36 etc.
The clamp device that flame trap is fixed to motor vehicle exhaust funnel comprises the clamp that is arranged symmetrically with, guide rod and with the round mouth folder of handle; The hinges fixing of described round mouth folder fixes on the described back-fire relief body connecting cylinder, Yi Bian round mouth tong handle end is provided with bolt, the another side correspondence has the hole; Described guide rod one end is connected to radially 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, different according to the motor vehicle exhaust mounting point, 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 tong handle length also should be 0.5～1.5m mutually.Like this, can get into the face installation and removal of car inside story for the part lorry.
