Constant temperature electrical heating urea liquid inlet pipe

Abstract

The invention discloses a constant temperature electrical heating urea liquid inlet pipe. The constant temperature electrical heating urea liquid inlet pipe comprises a urea pipe body; first heat shrink pipes are disposed on the two sides of the urea pipe body, a wire harness end ferrule is disposed on the first heat shrink pipe at one end, and a straight end ferrule is disposed on the first heat shrink pipe at the other end; a first urea pipe quick coupling and a second urea pipe quick coupling are installed at the two ends of the urea pipe body respectively; the urea pipe body is sleeved with a first nylon corrugated pipe jacket; the wire harness end ferrule is connected with a second nylon corrugated pipe jacket; the second nylon corrugated pipe jacket is connected with a plug-in part ferrule; a second heat shrink pipe is mounted on the plug-in part ferrule, and the plug-in part ferrule is connected with a two-wire plug-in part; a heating guide wire and a connected ventilation pipe are installed in the second nylon corrugated pipe jacket. The constant temperature electrical heating urea liquid inlet pipe is simple in structure and convenient to manufacture and mount and has the advantages of automatic temperature control, abrasion resistance, high temperature resistance and good point insulativity and fire resistance.

Description

technical field [0001] The invention relates to a constant temperature electric heating urea liquid inlet pipe. Background technique [0002] The traditional electric heating urea tube is an electric heater made of high-resistance metal alloy wire. The heating function will not change with the ambient temperature. It is a constant power heater. The temperature control of this heater must be limited by external equipment. And there are potential hidden dangers such as overheating and fire. Contents of the invention [0003] The purpose of the present invention is to provide a constant temperature electric heating urea liquid inlet pipe, which has a simple structure, convenient manufacture and installation, and has the characteristics of automatic temperature control, wear resistance, high temperature resistance, good point insulation and flame retardancy. [0004] In order to achieve the above object, technical scheme of the present invention is: [0005] A constant-tempe...
