Gas water heater with gas pressure sensors and control system for gas water heater

Abstract

The invention discloses a gas water heater with gas pressure sensors and a control system. The gas water heater comprises a gas water heater body, wherein the gas water heater body is provided with a gas inlet pipeline, a fan and a main controller; a fuel gas proportional valve, a stop valve and a sectional valve are further arranged on the gas inlet pipeline; a filter screen is arranged on the fuel gas proportional valve; and the gas water heater is characterized in that the oil-resistant fuel gas pressure sensors are arranged in the front of the filter screen of the gas proportional valve and the front of the sectional valve separately and serve as a primary gas pressure acquisition sensor and a secondary gas pressure acquisition sensor separately; and the pressure acquisition sensors, the gas proportional valve, the stop valve and the sectional valve are electrically connected to the main controller of the gas water heater, wherein the opening degree of the corresponding gas proportional valve is the proportional valve current value. The invention further discloses a multifunctional central gas water heater. According to the gas water heater and the control system, the gas pressure can be displayed in real time; and meanwhile, the accident or failure rate of the water heater can be reduced, and the parameters of the water heater can be automatically adjusted.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to the technical field of control of gas water heaters with gas pressure sensors. Background technique [0002] The gas proportional valve is one of the core components of the gas water heater. With the increase of the service life, the filter screen of the proportional valve inlet is clogged, gas impurities enter the proportional valve, and the proportional valve film is damaged, which may cause the performance of the water heater to decline, deflagration, leakage, etc. Gas or other safety accidents, these hidden dangers are not easy to be found in the early stage of use, only through manual investigation of faults or late accidents, similar faults cannot be strangled in the cradle; in addition, the maximum gas consumption, minimum gas consumption and The corresponding maximum air volume and minimum air volume are obtained based on laboratory test data or experience, so a...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a real-time monitoring of the primary air pressure and secondary air pressure of the gas water heater, which can prevent the deflagration of the water heater, air leakage, blockage of the air inlet, prompting of insufficient gas pressure, and other similar accidents or failures in real time. Cradle, and has an automatic adjustment mode to ensure the best combustion performance of the water heater, and can also be used as a gas water heater for automatic adjustment of water heater parameters in workshop production
