Pulsed solenoid valve solenoid valve body coil input wire to the positive pulse signal generated by the coil flux, moving core pull, open the valve. When the positive pulse signal input is stopped, the moving core release, moving core back to the initial state under the action of spring force, and close the valve 
 Addition, there are able to maintain self-holding type, stop the importation of a positive pulse or power failure, you need to input a negative pulse signal can be reset; the main principle of the pulsed solenoid valve is like a kind of automatic water-saving taps, you click The water will come out after a while, the water will automatically shut down, pulsed solenoid valve is connect you, the valve will open, open, you can adjust their own, and then when the time comes, to turn itself off. 
 Pulsed solenoid valve works is the use of electrical pulses into mechanical pulse of the powerful energy of the pulsating gas into the release of momentum in a short time a huge momentum with the accumulation of dust in the filter surface, dust collector efficiency and resistance are corresponding increase in the media on both sides of the pressure difference is large, will some have been attached on the filter small particles squeeze past precipitator efficiency decreased. In addition, the resistance is too high dust precipitator system air volume decreased significantly. Therefore, the the precipitator resistance reaches a certain value to cleaning. Cleaning can not be destroyed early layer, in order to avoid reduced efficiency. 
 Pulsed solenoid valve installed Cautions 

 A solenoid valve installation is perpendicular to the horizontal pipe, coil up. Conditions do not permit, allow ± 30 ° tilt. Otherwise, we can not guarantee normal use. 

 2, the solenoid valve on the nameplate parameters should be consistent with the actual requirements. 

 3, the arrow on the solenoid valve body is the medium flow. 

 4, in order to ensure the normal use of solenoid valves, solenoid valve before the installation of oil-water separator. 

 5, in a hazardous environment in order to prevent the occurrence of the spark may lead to explosions and other accidents should be explosion-proof solenoid valves. 

 6, prior to installation, please thoroughly purge the air bag and piping in order to avoid foreign body injury in the diaphragm caused by the solenoid valve failure. 

 7, when the solenoid valve failure, the device isolation and ease of maintenance, the recommended installation of bypass (bypass). 

 Temporarily install the solenoid valve can be stored at 0 ~ 40 ° C, relative humidity ≤ 80%, but non-corrosive gases indoors, if possible, avoid open storage. 

 Select all imports of high-quality brands: electromagnetic pulse valve but the heart of the dust removal equipment, the total price is about 5% of the overall price of the pulse jet dust collector; 1% cost of the air box pulse dust collector, the choice of the highest quality import pulse valve, the total equipment cost than the use of domestic valve has only increased by 1 to 2 percent. Pulse valve to save the cost of equipment and bear the risk of failure of the whole dust removal system is the most worthwhile. 
 Valve manufacturer with a long history: the valve manufacturer must have more than 10 years of production history and operation of successful cases, so as to ensure pulsed solenoid valve products have perfect quality assurance system, the real injection 10 million The annual exemption. 
 Choose the five-year free warranty period: the number of experimental pulse valve action sufficient to show the quality level of the valve, the diaphragm must go through years of natural aging factor test. Valve suppliers must provide free warranty period of the diaphragm and the solenoid coil, generally for five years. 
 Not just connected to the interface size of the aperture size: the pulse valve injection gas pulse valve, often can not determine the cleaning function. Some pulse valve design uses a small diameter of the diaphragm, but only to increase the interface. For example: the application of the valve diaphragm installed in the valve body of the 21/2 interface. So make the injection gas valve caused by inadequate cleaning system is poor.
