Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 1 and 2, the gas pipe for the natural gas engine comprises a gas pipe body 3, and the gas pipe body 3 sequentially comprises a first rubber layer 31, a second steel wire layer 32 and a second rubber layer 33 from inside to outside. Two ends of the gas pipe body 3 are respectively connected with a gas pipe joint, namely a gas pipe joint I21 and a gas pipe joint II 22. The inner end of the gas pipe connector I21 is connected to the gas pipe body 3, and the outer end of the gas pipe connector I21 is provided with a movable screw cap I11. The inner end of the gas pipe joint II 22 is connected to the gas pipe body 3, and the outer end of the gas pipe joint II 22 is provided with a movable nut II 12.
Due to the limitation of the internal space of the natural gas engine, in order to facilitate the connection between the gas pipe and other parts of the engine, the connection relationship between the gas pipe and other parts of the engine is more flexible, and the first gas pipe connector 21 is preferably an elbow connector.
The outer circumferential surface of the gas pipe body 3 is coated with a high-temperature-resistant fireproof layer 4. The fire-proof layer 4 is formed by weaving glass fiber yarns, the fire-proof layer 4 is formed by weaving the glass fiber yarns, and the fire-proof layer has high flexibility, so that the peripheral surface of the gas pipe connector I21 can be coated to protect the gas pipe connector I even if the gas pipe connector I is of a bent pipe structure.
Compared with organic fiber, the glass fiber has high temperature resistance, no combustion, good corrosion resistance, heat insulation and sound insulation, high tensile strength and good electrical insulation. But the performance is brittle and the wear resistance is poor. The glass fiber used as a reinforcing material for manufacturing reinforced plastics or reinforced rubber has the following characteristics: high tensile strength and small elongation (3%); the elasticity coefficient is high, and the rigidity is good; the elongation within the elastic limit is large and the tensile strength is high, so that the impact energy absorption is large; the glass fiber is inorganic fiber, and has incombustibility and excellent chemical resistance; the water absorption is low; the dimension stability and the heat resistance are good; has good processability, and can be made into products with different shapes such as strands, bundles, felts, woven fabrics and the like. The glass fiber has better elasticity, fire resistance and temperature resistance, so the glass fiber can be used for weaving a fireproof layer.
When the gas pipe outside catches fire, high temperature resistant flame retardant coating 4 just can effectively protect the gas pipe, and then guarantees the reliability of natural gas engine work.
The technical features (such as the first gas pipe joint, the second gas pipe joint, the first movable nut, the second movable nut, etc.) referred to in this specification are only for distinguishing the technical features, and do not represent the positional relationship, the installation sequence, the working sequence, etc. among the technical features.
