Description
Technical field
The utility model relates to a kind of sebific duct, relates in particular to a kind of fork truck air filter sebific duct.
Background technique
Fork truck air filter sebific duct is the pipeline of clevis car engine and air-strainer, because out exhaust gas temperature is high and contain a lot of corrosive impurity in the motor, larger to the corrosivity of rubber, existing fork truck air filter sebific duct generally adopts steel pipe firmly to connect.But because the vibrations of motor, this fork truck air filter sebific duct easily produces strenuous vibration thereupon, vibrations easily cause fork truck air filter sebific duct bayonet socket place loosening, thereby leak out the waste gas of crossing filtration without air-strainer, make engine operation cylinder knot dirt and reduce working life of motor, and the motor place is easily on fire, and the fork truck air filter sebific duct of use need to possess flame retarding to promote Security.
The model utility content
The purpose of this utility model is to provide a kind of fork truck air filter sebific duct, solved because the vibrations of motor, existing fork truck air filter sebific duct easily causes the loosening waste gas that spills in fork truck air filter sebific duct bayonet socket place because of vibrations, reduce the working life of motor, and fork truck air filter sebific duct need to possess the problem of flame retarding.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of fork truck air filter sebific duct, comprise tube wall, tube wall comprises braid, the aramid line layer, sprayed the anticorrosion enamelled coating that forms by chlorinated rubber anticorrosive paint, glued together inner rubber layer and the outer rubber layer that forms by natural rubber, braid is interwoven by the polyester line, the braid inner and outer surface is fixedly installed respectively inner rubber layer and outer rubber layer, the outer surface of outer rubber layer is fixedly installed the aramid line layer, the internal surface of inner rubber layer is fixedly installed anticorrosion enamelled coating, the aramid line layer is interwoven by warp thread and weft yarn, warp thread and weft yarn adopt aramid fibre, and the internal surface at tube wall two ends evenly is fixedly installed respectively the seal ring of multilayer.This fork truck air filter sebific duct arranges braid makes the intensity of sebific duct tube wall high, the outer surface of outer rubber layer is fixedly installed the aramid line layer, aramid line has high temperature resistant, fire protection flame retarding, lightweight, intensity is high, modulus is high, dimensionally stable, shrinkage is low, anti-puncturing, abrasion performance, heat resistance, resistance to chemical attack, good mechanical property, the advantages such as dielectricity is good, can prevent that outer rubber layer is exposed in the atmosphere, prevent rapidly aging and corrosion of outer rubber layer, and can promote the flame retarding of fork truck air filter sebific duct self, the internal surface of inner rubber layer is fixedly installed the anticorrosion enamelled coating that is formed by the chlorinated rubber anticorrosive paint spraying, can prevent that inner rubber layer from directly contacting with the different medium water source, prevent rapidly aging and corrosion of inner rubber layer, make this fork truck air filter sebific duct meet requirement as the pipeline of clevis car engine and air-strainer, and the internal surface at tube wall two ends evenly is fixedly installed respectively the seal ring of multilayer, has strengthened the sealing between fork truck air filter sebific duct forklift engine and air-strainer, and the soft connection that this tube wall employing quality of rubber materials is the master also can slow down the vibrations that forklift engine brings, prevent that waste gas from directly spilling without air-strainer, promote the working life of motor.
As preferably, described braid is interwoven by warp thread and weft yarn, and warp thread and weft yarn adopt the polyester line.By this structure braid is interweaved closely, the braid that the polyester line interweaves more is conducive to strengthen the intensity of fork truck air filter sebific duct.
As preferably, described seal ring is the elastic caoutchouc seal ring.Be convenient to lift-off seal ring sealing by the seal ring that elastic caoutchouc is made.
As preferably, the cross section of described seal ring is semicircle.Be convenient to seal ring by this structure and well finish seal operation.
The cross section of described seal ring can also be zigzag fashion.
The beneficial effects of the utility model are: (1), this fork truck air filter sebific duct have been strengthened the sealing between fork truck air filter sebific duct forklift engine and air-strainer, prevent that waste gas from directly spilling without air-strainer, promote the working life of motor; (2), be provided with the aramid line layer, can promote the flame retarding of fork truck air filter sebific duct self.
