Flameout protection device domestic gas safety

Common thermocouple type flame protection system on the market. This system is composed of two parts, a thermocouple and the magnet valve. Thermal electric potential difference when the thermocouple is heated, it enters the coil generates a magnetic field of the solenoid valve operation. Once the thermocouple detection of the flame is extinguished, the potential thermocouple produced quickly reduced to zero, the solenoid valve under the action of the spring off the gas valve. This system starts to warm-up for about 10 seconds, some customers feel inconvenient and habits. Its flame time control in about 40 seconds, there are still leak risks, but do not turn off the stove than securing device much safer.

Gas stove with a gas leak or smell causes

Gas stove with a gas leak or smell causes:
a, hose rupture or connected, replace the hose and fixed;
b, Gas cooker valve seal aging joints, replace the seals;
c, Gas burner valves prolonged failure, replace the valve;
d, stove unlit, troubleshooting, re-ignition;
e, from the fire or from the flame, remove from the fire (according to previous solutions);
f, joint leakage, repair or replace the joint.

Gas valve and air valve to achieve a reasonable linkage

Gas valve and air valve to achieve a reasonable linkage, that is, to ensure that the burner fuel ratio is equal to the design value. We need to find out the actual flow of gas cooker safety valve at different opening degrees to determine the required air flow rate by the gas flow rate and the actual design of air-fuel ratio value. Then based on the actual work flow characteristics of the air valve, determine the required air valve opening. Finally, the valve opening degree of the relationship between the corresponding linkage design. Ball is a large flow capacity, short trip switch, the noise is small. Therefore, commercial gas stove are used as a ball valve.

Commercial gas stove safety combustion system including

Commercial gas stove safety combustion system including: premix burners, gas valves, air valves, fans, piping, joint institutions. Wherein the opening of the gas valve linkage is the signal on the air valve opening degree control, mechanical transmission and electronic transmission in two ways. By establishing linkage between an accurate mathematical model of gas between the valve and the air valve, thus ensuring commercial gas stove premix fuel ratio accuracy.

Current commercial gas stove products

Current commercial gas stove products, there are many problems need to be solved and improved, these problems include: gas stove valve failure rate is high, low thermal efficiency. Commercial gas cooker product energy saving potential. It is estimated that, if the food and beverage industry are switching to energy-saving gas stove, only Beijing, annual savings of natural gas 5 000 × 104 m3, equivalent to the amount of natural gas using the city's commercial gas cooker month. Therefore, the use of new technologies gas burner valve to improve thermal efficiency and reduce carbon monoxide and nitrogen oxide emissions work is imminent.

Flameout protection device role

Gas Cooker valves flameout protection device role is: When the gas in the combustion process, the flame accidentally goes off automatically shut expire sources to ensure safe use. On some of the more high-end household domestic gas, generally used flameout protection device (embedded domestic gas must have a flame protection). gas cookers stoves in daily use, sometimes due to water, soup or overflow effluent and the flame extinguished. Unattended or without safety devices, the gas will continue to flow, a large gathering around the burner in case of fire easy to fire or explosion accident, endangering personal safety. If you have flameout protection device, once the flame is extinguished, it will feel the heat because the temperature of the element or the potential drop leaving the executive body quickly reset, shut off the gas to avoid gas leakage, so it plays a security role.
