Technical requirements for electromagnetic pulse valves

Technical requirements for electromagnetic pulse valves:

1. The working pressure of the product is 0.1 MPa~0.7 MPa, and the medium is air that has been degreased and dehydrated.

2. Under the nominal gas source pressure of the product, when the working voltage of the solenoid valve is 85% of the rated voltage, the opening response time of the electromagnetic pulse valve should be less than 0.03 s.

3. When the working gas source pressure is 0.1 MPa, the pulse valve can be closed.

4. The product should be able to withstand a gas source pressure of 0.8 MPa.

5. Under the specified environmental conditions, the insulation resistance of the electromagnetic coil to the shell should be greater than 1 MΩ.

6. Under the condition of a room temperature of 5 degrees to 35 degrees and relative humidity not exceeding 85%, the electromagnetic coil can withstand a voltage of 50 Hz and 250 V to the shell, and there is no breakdown phenomenon for 1 min.

7. The electromagnetic pulse valve should be able to work normally after being subjected to vibration with a frequency of 20 Hz, a full amplitude of 2 mm, and a duration of 30 min.

8. Under normal use conditions, the cumulative service life of the diaphragm should be greater than 800,000 times.

9. The valve surface has no obvious coating peeling, scratches, burrs, or other damage.

10. The air supply pressure of the large-caliber ultra-low pressure electromagnetic pulse valve for rotary injection is less than 0.1 MPa. It uses compressed air and is not affected by the simultaneous use of air in the pipeline network. The operation is stable and reliable. (0.05~0.1 MPa)
