Antifreezing thermal-insulated hose

Abstract

The invention discloses an antifreezing thermal-insulated hose which comprises a hose body, a first connector, a second connector, a heating cylinder, a third connector, a hose, carbon fiber cloth, apolyurethane thermal insulation layer, an asbestos filling layer, a protection tube, a stainless steel cylinder, a heating bar and a shield. The heating cylinder mainly comprises the stainless steel cylinder and the heating bar; when a diesel engine is started in winter, a switch can be controlled to enable the heating bar to work; and under the action of the heating bar, when diesel passes through the stainless steel cylinder, the temperature of the stainless steel cylinder rises, the heating to the diesel when the diesel engine is started in winter is facilitated, and the condition that thediesel engine is difficultly started in winter is beneficially reduced. The thermal insulation performance and the antifreezing performance are higher, the condition that when the diesel flows throughthe hose, the temperature of the diesel is reduced due to external low temperature is greatly reduced, the combustion rate of the diesel in winter is beneficially ensured, and the energy efficiency of the diesel engine is ensured.

Description

technical field [0001] The invention relates to an antifreeze and heat preservation hose, in particular to an antifreeze and heat preservation hose, which belongs to the technical field of diesel hose applications. Background technique [0002] A diesel engine is an engine that burns diesel to obtain energy release. The advantages of a diesel engine are large torque and good economic performance. The working process of a diesel engine has many similarities with a gasoline engine. Each working cycle also undergoes intake, compression, and work. , Exhaust four strokes, diesel hose is an indispensable device to connect the oil circuit of the diesel engine. [0003] However, most of the existing diesel hoses cannot heat the flowing diesel oil. In winter, due to the decrease of the external temperature, the diesel oil becomes viscous, its flow performance deteriorates, and the diesel oil cannot be well atomized, which will cause temporary difficulty in starting. , which is not c...

Problems solved by technology

[0003] However, most of the existing diesel hoses cannot heat the flowing diesel oil. In winter, due to the decrease of the external temperature, the diesel oil becomes viscous, its flow performance deteriorates, and the diesel oil cannot be well atomized, which will cause temporary difficulty in starting. , which is not conducive to the start of the diesel engine in winter, and the existing diesel hose has poor thermal insulation and antifreeze capabilities. To ensure the energy efficiency of the engine in winter, there are certain deficiencies
