What reliability tests are conducted for the electronic drain valve?

1. Pressure resistance test: Maintain 1.5 times the rated working pressure (1.65 MPa) for 5 minutes. The valve body should not deform, rupture or leak.

2. Durability test: Under rated voltage and 0.8 MPa air pressure, perform 100,000 switching cycle tests. After the test, the sealing performance and operation performance should not be degraded.

3. Protection level test: Conduct IP68 protection test in accordance with GB/T 4208-2017. The dust protection test lasts for 8 hours without any dust entering, and the immersion test is conducted at a depth of 1 meter for 24 hours, with the function remaining normal.

4. Vibration test: Perform sweep frequency vibration test in accordance with GB/T 2423.10. The frequency range is 10 to 500 Hz, with an acceleration of 10g. Each direction lasts for 8 hours. After the test, there should be no loosening, no damage, and the function remains normal.

5. Temperature shock test: Perform temperature cycling from -40℃ to 80℃. The conversion time is ≤ 1 minute, the holding time is 2 hours, and the cycle is 100 times. After the test, there should be no cracking, no leakage, and the function remains normal.

What are the packaging specifications for the timed electric auto drain valve?

1. Inner packaging: Each product is wrapped with a thick bubble bag for protection during transportation to prevent scratches and bumps. 2 pcs are placed in a small double-recessed paper box, with the box size being 90×55×80mm.

2. Outer packaging: It uses AB-shaped double-recessed paper boxes, with a burst strength of ≥1500kPa and a side pressure strength of ≥7000N/m. The outer box size is 455×310×270mm.

3. Packaging quantity: Each box contains 69 small boxes, totaling 138 products, arranged in 3 layers with 23 boxes per layer, neatly arranged.

4. Box sealing identification: It uses transparent tape to seal the box in a cross pattern, and the product identification is pasted on the side of the outer box, indicating the model, quantity, batch number, and production date.

5. Single-box parameters: The weight of each product is 0.14kg, and the total weight of each box is approximately 19.97kg, making it convenient for manual handling.

3. Quality traceability: Each product has a unique batch number, which can be traced back to the production date, production line, inspector, and raw material batch, achieving full life cycle quality traceability.

Q: What is the working current of the condensate drain valve? How large of an fuse should be used?

A: The working current during drainage is approximately 0.26 to 0.4A (DC 24V), and during heating it is approximately 0.27A. The maximum total current is about 0.7A. It is recommended to use a 5A fuse for each drainage valve. When multiple drainage valves share one fuse, the current capacity should be calculated as the total number multiplied by 1.5 times. The power supply line is recommended to use an automotive wire of 0.5mm² or above, and the line voltage drop should not exceed 1V.

Q: What is the tightening torque for the installation of condensate auto drain? Is it necessary to apply thread sealant?

A: The recommended tightening torque is 35 to 40 N·m, with a maximum of no more than 45 N·m. Insufficient torque will result in poor sealing and air leakage, while excessive torque will cause the valve body to deform or the threads to slip. During installation, a copper composite gasket or nitrile rubber composite gasket must be used, relying on end face sealing. Thread sealant is not required; instead, it may lead to sealing failure or make future disassembly difficult.
