Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the redrafting method to amend and adopt ISO 23551-6.2014 "Safety and Control Devices for Gas Burners and Burning Appliances"

Special requirements Part 6.Thermoelectric flameout protection device".

Compared with ISO 23551-6.2014, this standard has many structural adjustments. Appendix A lists this standard and ISO 23551-6.

The.2014 chapter number comparison list.

Compared with ISO 23551-6.2014, this standard has technical differences, and the clauses related to these differences have been passed on the outer side of the page.

The vertical single line (|) of the position is marked, and a list of the corresponding technical differences and their reasons is given in Appendix B.

This standard is consistent with GB 16914-2012 "Safety Technical Conditions for Gas Burning Appliances". The support of this standard is given in Appendix C.

3 Terms and definitions

The following terms and definitions defined in GB/T 30597 apply to this document. For ease of use, the following is repeated

Certain terms and definitions in GB/T 30597.

3.1

Thermoelectric flameout protection device thermoelectricflamesupervisioncontrols

The valve body, solenoid valve, and thermocouple can respond to the thermoelectric potential generated by the thermocouple, and make it lead to the main burner or the main burner and ignition

The gas passage of the burner is opened, and after the monitored flame is extinguished, the device can automatically cut off the gas passage.

Note. See Appendix D for the form and composition diagram of the flameout protection device.

3.2

Solenoid valve solenoidvalve

A type of thermoelectric potential generated by a thermocouple installed in the valve body to maintain the open state of the gas path, and can be used after the monitored flame is extinguished

The part that closes the gas passage.

3.3

Thermocouple

The flame sensing element responds to the temperature of the monitored flame to generate thermoelectric potential.

3.4

Ignition interlock

As long as the passage to the main burner is opened, the component that can prevent the igniter from operating.
