CJ/T 30-1991Thermocouple electromagnetic protector of extinguishment for gas appliance (English PDF)

Foreword

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

This standard replaces CJ 30-1999 "thermoelectric burner flameout protection device", compared with the CJ 30-1999, the main technical changes are as follows.

--- Increased use of auxiliary energy thermoelectric burner flameout protection device (see Chapter 1, Appendix E);

--- Increased torsion and bending, rated flow, operating characteristics and air tightness requirements (see 6.3,6.4,6.6.1,6.6.5);

--- Modify the thermoelectric gas flameout protection device classification (see Chapter 4, 1999 edition of Chapter 4);

--- Modify the valve opening time, valve closing time requirements (see 6.6.4, 1999 version 5.2.3);

--- Deleted the establishment of models (see 1999 version 4.4);

--- Removed the open valve current requirements (1999 version 5.2.2).

This standard uses redrafted Law Amendment adopts BSEN125.:2010 "gas appliance flame control device thermoelectric flame monitoring device." this standard and BSEN125.:2010 compared to more structural adjustment, Appendix A lists the standard and BSEN125.:2010 chapter Article number control list.

This standard compared with BSEN125.:2010 there are technical differences, the provisions of these differences have been passed in the outer margin of the page margin Set the vertical single line (-) marked, Appendix B shows the corresponding technical differences and their causes list.

This standard is consistent with GB 16914-2012 "gas burning appliances safety conditions," Appendix H gives the standard branch GB 16914-2012 with the basic requirements of the provisions of the corresponding table.

This standard made the following editorial changes.

--- Modify the standard name as "thermoelectric burner flameout protection device";

--- Removed BSEN125.:2010 cover, directory, preface and description;

--- Removed BSEN125.:2010 Appendix A (informative) "countries commonly used gas connection";

--- Removed BSEN125.:2010 Annex C (informative) "Gas tightness test --- pressure loss method";

--- Removed BSEN125.:2010 Appendix D (normative) "pressure loss method converted into leakage";

--- Removed the BSEN125.:2010 Appendix F (normative) "EU quality 97/23/EC in the safety Annex and pressure Additional requirements for attachments ";

--- Removed BSEN125.:2010 Appendix G (normative) "pressure parts material";

--- Removed BSEN125.:2010 Appendix H (informative) "compression parts additional materials";

--- Removed BSEN125.:2010 Appendix ZA (Informative) "on gas fuels EU standards and EC directives 2009/142/EC correspondence between;

--- Added Appendix C (informative) "flameout protection device type and composition";

--- Added Appendix D (informative) "flame sensing thermocouple installation requirements";

--- Added Appendix E (normative) "use auxiliary energy flameout protection device special requirements";

--- Added Appendix F (informative) "Solenoid single test method." this standard proposed by the Ministry of Housing and Urban Standard and Design Institute.

This standard by the Ministry of Housing and Urban Gas Standardization Technical Committee centralized.
