Last month, France praised the rubber diaphragm industry chain adjustment valve DU>Cycle adjustment valve (Toeflon) SCG353A050 solenoid valve diaphragm.
The working pressure of rubber diaphragm products is 01MPa~07MPa, and the medium is air that has undergone oil and water removal treatment.
1. Under the nominal gas source pressure state of the product, the pressure of the rubber diaphragm on the medium is reversed (pulse) and has the properties of a pulse valve diaphragm, which is 76%.
2. Under the nominal gas source pressure state of the product, the output pressure of the rubber diaphragm for the medium pressure gauge is 05MPa, at -7L/min, and the highest temperature should be selected.
3. Under specified environmental conditions, the insulation resistance of the electromagnetic coil to the shell should be greater than 1M Ω.
4. Under the condition of room temperature ranging from 5 ° C to 35 ° C and relative humidity not exceeding 85%, the electromagnetic coil can withstand a voltage of 50Hz and 250V to the shell for 1 minute without any breakdown phenomenon.
5. The Electromagnetic pulse valve shall be able to work normally after withstanding the vibration with frequency of 20Hz, full amplitude of 2mm and duration of 30min.
6. When the working voltage of the Electromagnetic pulse valve is 85% of the rated voltage under the nominal air source pressure of the product, the opening response time of the Electromagnetic pulse valve shall be less than 003s.
7. Under specified environmental conditions, the electromagnetic coil can withstand a voltage of 50Hz and 250V on the shell for 1 minute without breakdown.
8. Under the condition of room temperature ranging from 55 ° C to 150 ° C and relative humidity not exceeding 85%, the electromagnetic coil can withstand a voltage of 50Hz and 250V to the shell for 1 minute without any breakdown phenomenon.
9. The Electromagnetic pulse valve shall be able to work normally after withstanding the vibration with frequency of 20Hz, full amplitude of 2mm and duration of 30min.
10. When the working voltage of the Electromagnetic pulse valve is 85% of the rated voltage under the nominal air supply pressure of the product, it should be less than 003s.
11. Under specified environmental conditions, the electromagnetic coil can withstand a voltage of 50Hz and 250V on the shell for 1 minute without breakdown. 06.
