6 Qualification inspection and testing
The production should be carried out according to the approved drawings and technical documents during the production period. The quality system should ensure that the quality of each batch of products meets the requirements of the test section.
6. 1 Inspection classification
6.1.1 Type inspection
6.1.1.1 For each type and specification of pipeline network, before the product is put into production, a comprehensive inspection of various performance factors must be carried out. If the following conditions are found, the type inspection shall be reported to the industry for review: a) Qualitative appraisal of new product development:
b) After formal production, if the structure, material, craftsmanship, etc. are relatively large, it may affect the overall performance of the product; if a larger quality accident occurs:
The product is produced for more than one year, the production should be resumed: e) During normal production, a type inspection shall be carried out once a year: The supervisory agency shall carry out a special inspection according to the requirements
6.1.1.2 Product type inspection shall be carried out in accordance with the provisions of this part and the items shall be inspected monthly. 6.1.2 Factory inspection
Products shall be inspected and checked by the relevant department and scheduled at 5.1.5,7,F,! 6.2 Batch test: The same materials and accessories are used for assembly or production of the same bow and the same specifications. 6.3 Sampling: The machine force method is used, and the number of samples is not less than 12 units. 6.4 Inspection procedures: The rain alarm debugging process is carried out according to Figure 4. 7. 1-Appearance test: 5, 2-Workmanship: Deterioration test seat: 3-Aging test: 54, aging ...

6.5 Inspection result judgment
Part II.1--.13 Enterprise Standard. This batch of products was judged as qualified products, TA5135.5-2003
This department will.74. There is a non-conforming item: The batch of products is classified as non-conforming products. The rest of the items are not in compliance with the fast time, and the sample is allowed to be tested separately. There is still one phenomenon that is unqualified. This product is not in compliance with the situation, and the label and instruction section
7.1 Label
The marking of the rain alarm valve shall comply with the provisions of 4.1.2. 7.2 Instructions for use
The rain alarm valve shall have an instruction manual on the front of its packaging. The instruction manual shall at least include the product name, specification and model, operating environment, storage conditions, production date, production data standards, necessary usage, installation instructions and installation instructions, quality assurance, manufacturer's name, location and contact information, etc. 8 Packaging, transportation, storage
8.1 Packaging
8.1.1 The rain alarm valve shall be fixed in the box. 8.1.2 The product packaging shall be accompanied by instructions for use and a certificate of conformity. 1.3 The packaging shall indicate modifications, emergency conditions, safety restrictions, and storage protection conditions, etc. 8.2 Transportation
During transportation, keep the amount of waste water down and limit the amount of waste water during loading and unloading. 8.3 Storage
The waste water should be stored in a ventilated workroom. It should not be stored together with biomass. The storage temperature should be -10. GB 5135.5:2003 (Normative Record) Hydraulic resistance test method 4.1 Make sure the test object flows through a calibrated standard nozzle at a flow rate of 4.5m/s. The pressure gauge is installed on the water supply side of the test valve. The pressure loss of the two nozzles should not be lower than the test pressure. 4.2 Adjust the spray pressure to make the test pipe drop velocity remain at 1.5m/s. The total pressure loss of the test pipe between the two positive ports of the proposed valve is directly measured by the flow meter. 4.3 Use a straight pipe section with the same nominal diameter to replace the test valve: use a positive pressure gauge to measure the positive pressure loss of the test pipe between the two pressure ports under corresponding flow reverses.
A, 4 From the total force of the test tube between the two ports of the raindrop, the three forces of the test tube head are reduced by the three forces of the test tube head between the inner and outer ports. The water and moment of the previous reading can be obtained. Appendix B

B.1 In the fully open position, the clearance between the valve head and the throat of the body should not be less than 19mm for iron. For metal or stainless steel, it should not be less than
B.2 In the closed position, there is at least 3mm of semi-final clearance between the valve head and the inner edge of the foot. H.3 The annular clearance between the shaft and the shaft can be no less than 3mm. H.4 The diameter of the shaft can be no less than 1.12=mmB.5 The axial clearance between the valve head and the bearing surface of the valve head should not be less than 1.125mm1. .6 For the moving parts of the valve body, the minimum radial distance between the moving parts should not be less than 3 mm, the minimum radial distance between the moving parts and the fixed parts should not be less than 1.2 mm, and the distance between the shaft pin, bearing and other parts should not be less than 3.11 mm.
