The standard of automatic gas valve assembly for gas-fired heating water heater passed the examination and approval of experts - the standard reached the international advanced level

in the afternoon of January 6, 2020, Guangdong gas-fired heating water heater chamber of Commerce organized a meeting in Shunde, Foshan to examine and approve the standard of Guangdong high-quality group, automatic gas valve assembly for gas-fired heating water heater. Biont has obtained the capital injection from battel and the United Soybean Board. On the afternoon of January 6, 2020, the Guangdong Chamber of Commerce for gas heating water heaters organized a review meeting of the Guangdong quality group standard automatic gas valve assembly for gas heating water heaters in Shunde, Foshan

six experts from Guangdong Institute of standardization, China Electric Appliance Research Institute, oenergy, Ruima, ashdenton and Yingxue form an expert review panel. Huangjianping, chief researcher of Guangdong Institute of standardization, serves as the leader of the expert review panel

at the beginning of the meeting, Secretary General Lou Ying said that the standard of Guangdong high-quality automatic gas valve assembly for gas heating water heater responds to the construction plan of "Guangdong high quality" standard system, and is the accessory standard matching the complete machine standard - t/gdgcc domestic gas heating water heater. It aims to produce high-quality Guangdong products by implementing the standards of some manufacturers and industry standards that are stricter than the national standards, Build a strong province by building a brand

Pangzhiyong, the Secretary General of louying chamber of Commerce, the drafter of the standard and the general manager of Guangzhou JINGDING, made a preparation report, focusing on the technical difficulties and solutions of the standard and the verification test of main performance indicators

1. In the course of the experiment, pangzhiyong, general manager of JINGDING, reviewed the full text of the standard, reviewed it item by item, and unanimously passed the review of the automatic gas valve assembly for gas-fired heating water heater. It is believed that the standard should be formulated on the basis of the preparation team's full investigation of the technical status of the automatic gas valve for gas-fired heating water heater at home and abroad, the summary of practical experience, and the full verification test, The classification and grouping, structure and materials, requirements, test methods, inspection rules, signs, installation and operation instructions, packaging, transportation and storage of automatic gas valves for gas-fired heating water heaters are specified. The product specifications for automatic gas valves for high-quality gas-fired heating water heaters in Guangdong are put forward, which have strong pertinence, practicality and operability

in addition, the three indicators of rated flow, opening function and vibration resistance in the standard are better than the current ISO international standards and national standards; Added 9 technical requirements to ensure product performance, including overshoot, minimum output pressure, return difference, minimum/maximum output pressure ratio, and drop impact resistance; The four indexes of air tightness, valve noise, heat resistance and cold resistance are stricter than or meet the requirements of domestic gas heating water heaters (t/gdgcc). The standard has well handled the technical difficulties in the standard. The verification test of main performance indicators is scientific and reasonable. The overall standard level has reached the international advanced level. It is helpful to improve the product accuracy grade of gas valves for gas-fired heating water heaters in Guangdong Province: 0.01N, accuracy: better than ± 1% of the indicated value, measurement range: 2%~100%, measurement accuracy: better than ± 1% of the indicated value, resolution: 0.01mm, Speed: 1mm/min ~ 500mm/min stepless speed regulation quality and production technology level have positive significance
