Building air duct
Ventilation direction or ventilation head: 2 Adjustment: 3-Suspension type: small ventilation: 5-Pipe flange. Self-%-Fireproof courtyard or ventilation room: a water fan 3.7 Service type air conditioner clear cattle allowable burrs, mosquitoes, the surface should be smooth 3.3 The joints should be uniform and must not have defects such as rust, air induction, bite, welding drops, condensation, etc. 3.4 Steel ventilation accessories should be rust-proofed (large castings and processing can be removed, and the user can send it to the %2 level requirements in GB8323) 3.5 Refers to the variable The steel parts of the chain are treated with zinc Cn/764, and the degree of plating is not more than 3Ur1. After the parts are processed, the B~/Z32 is provided with an oxidation treatment, and the National Technical Supervision and Administration approved it on March 28, 1996 and implemented it on 11-01, 1996. 3-6 Pay attention to the long-term operation of the lifting and rotating parts, and the parts of the parts should be light and effective. The parts of the parts should be grease-free. 3.B can be airtight, and the ventilation parts and parts that need to maintain the ventilation should have good sealing performance. This performance is tested quickly. After the test, there will be no evidence of mixing. 3.9 The ventilation warehouse has enough water to make the plate have a positive water test: after the test, there should be no mixing conditions. 3 .1 Fire and smoke resistance is the fire resistance requirement of S1AS convention. It is necessary to carry out fire resistance test. It has good insulation performance (maximum 20M0) power distribution monitoring performance (total pressure V) and self-closing performance to resist fire. It can work normally in various environments during operation.
3.11 After the product is connected, the upper layer (including zinc, oxidation, etc.) must be removed: the product must be stored or packaged before it is exposed to the outside.
4 Test method
41 Water pressure test
The water pressure test should be carried out according to the test pressure requirements in Table 1. The water test lasts for 5m. The test results should meet the requirements of %! 1

Discussion
For the original
Design
For ventilation and ventilation not listed in this table, it can be or its own equipment, etc. The original small state is selected for the test level 4.2 Flushing test
During the flushing test, the diameter of the flushing spray shall not be less than 2.5m. The water spray pressure shall not be less than 1.25MPE, the flushing distance shall not exceed 1.5m, and the flushing time shall be 3mm. The test results shall meet the requirements of 3.5. 4.3 Fire resistance
Fire resistance limit test shall be continued. There is a fire breaker temperature of 70°C and the fire resistance limit test of the damper shall be within 50°C. When the temperature reaches 141°C, the system shall be gradually activated and the closing case shall be activated. 5 Inspection rules
5.1 Appearance inspection shall comply with the requirements of 3.2 and 3.3. 5.2 Inspection or performance inspection shall comply with the requirements of 3.6. 5.3 Test the parts according to the first requirement. If defects are found during the test, they shall be repaired and disinfected, and then tested again. If the pressure of the test is to be re-tested, it shall be increased by 20% compared with the first test. If defects are found again in the second test, the parts shall be reported to the warehouse for inspection. 5.4 After acceptance, the manufacturer shall issue a certificate of quality. 6 Marking and packaging
6.1 The attachment shall have the following signs:
Manufacturer name or logo;
Machine name:
± Production batch number
d. Qualified food. bzxz.net
6.2 Packaging
