Electronic heating control device of natural gas reducing valve for natural gas automobile

Abstract

The invention relates to an electronic heating control device of a natural gas reducing valve for a natural gas automobile, which comprises a ceramic heater arranged outside a high-pressure chamber and a heat-preserving shell which is arranged outside the ceramic heater and is made of a heat-insulating material, wherein the heat-preserving shell is arranged in a metal shell and is a hollow shell; and a preheating water inlet and a preheating water outlet which are communicated to the inner cavity of the heat-preserving shell respectively are formed on the heat-preserving shell, and a high-pressure air inlet and a high-pressure air outlet which are communicated with the inside of the high-pressure chamber are formed on the heat-preserving shell. The electronic heating control device has a simple structure, reasonable design and low cost, and is easy and convenient to use, operate and maintain; and before the automobile is started, the high-pressure chamber is preheated by adopted the ceramic heater, so the problem of frosting in the high-pressure chamber when the natural gas automobile starts in cold winter is solved effectively.

Description

technical field [0001] The invention relates to an electronic heating control device, in particular to an electronic heating control device for a natural gas decompression valve for a natural gas vehicle. Background technique [0002] At present, the pressure reducers used in natural gas vehicles for public transportation are basically preheated with hot water. Frosting occurs in the high-pressure chamber, which blocks the high-pressure natural gas of the car, thereby causing the car to fail to work normally. Every year, when the public transportation in big cities leaves in the morning, one or several faulty vehicles are often parked in a section of the road. Once the high-voltage chamber is frosted and a fault occurs, it is difficult to eliminate it, and it usually takes 1-2 hours to solve it. Especially in the cold winter, the lower the temperature, the higher the failure rate of frosting in the high-voltage chamber of public transport vehicles, which seriously affects t...
