According to the requirements of mandatory fire protection product certification, what are the requirements for the inspection of general valve (valve inspection) products? CCCF online certification takes you to understand!
Fire damper is a general term, mainly including: butterfly valve, gate valve, check valve, etc. It belongs to a part of sprinkler irrigation equipment, sprinkler products (sprinkler head. water mist sprinkler head. household sprinkler head. ESFR sprinkler head for early suppression and fast response. sprinkler head to expand coverage. household sprinkler head. water curtain sprinkler head. wet alarm valve. dry alarm valve. Pressure switch. Fire general valve) and so on.
Therefore, for the inspection of fire general valve products, the following inspection items are generally required for each component of the general valve:
1) In the fire gate valve identification unit, the model with the largest nominal diameter and the highest rated working pressure should be used as the main inspection model, according to 6.1.1.6.1.5 of GB5135.6-2018 "Automatic Sprinkler System Part 6: General Valves". 6.1.8.6.2 Project testing as the main detection mode.
2) In the fire ball valve identification unit, the model with the largest nominal diameter and the highest rated working pressure shall be used as the main inspection model, and the implementation of 6.1.1.6.1.5.6.1.8.6.3 "Sprinkler System Part 6: General Valves" project testing.
3) In the fire solenoid valve certification unit, the model with the largest nominal diameter and the highest rated working pressure should be used as the main inspection model, according to 6.1.1.6.1.5 of GB5135.6-2018 "Automatic Sprinkler System Part 6: General Valves". 6.1.8.6.4 Test for each item.
4) The entrusting unit of fire butterfly valve certification selects the model with the highest nominal diameter and the highest rated working pressure as the main inspection model, GB5135.6-2018 "Sprinkler System Part 6: General Valve" 6.1.1.6.1.5. 6.1.8.6.5 Project testing.
5) In the fire shut-off valve certification unit, the model with the largest nominal diameter and the highest rated working pressure shall be used as the main inspection model, and the item test of 6.1.1.6.1.5.6.1.8.6.6 shall be performed: Automatic sprinkler system Part 6: Universal valve.
6) In the fire signal gate valve certification unit, the model with the largest nominal diameter and the highest rated working pressure should be used as the main inspection (valve inspection) model, and the implementation of GB5135.6-2018 "Automatic Sprinkler System" Part 6: General Valves, 6.1. 1.6.1.5.6.1.8.6.7.1.1.6.7.2~6.7.6 test.
7) In the fire signal ball valve certification unit, the model with the largest nominal diameter and the highest rated working pressure should be used as the main inspection model. 6-6.7.6-6.7.6-6.7-6.7.6 test.
8) In the fire signal butterfly valve certification unit, the model with the largest nominal diameter and the highest rated working pressure should be used as the main inspection model, GB5135.6-2018 "Automatic Sprinkler System" Part 6: General Valves, 6.1.1.6.1.5.6.1 .8.6.7.1.3.6.7.2~6.7.6 inspection.
