The classification of the electromagnetic pulse pneumatic valve and technical requirements

electromagnetic pulse pneumatic valve refers to the given moment when electrical signals through the pneumatic valve of air, like pulse phenomena have the change of the short fluctuation, therefore calls the pulse pneumatic valve. Industry standard definition of electromagnetic pulse pneumatic valve for pneumatic valve and pulse pneumatic electromagnetic pilot valve together, pneumatic diaphragm valve controlled by electrical signals. The classification of the electromagnetic pulse pneumatic valve

pulse pneumatic valve is pulse blowing dust device of actuators and key components, mainly divided into rectangular type, submerged type, straight through three categories, each category has several specifications, through to mouth from mm - Mm, there is a large size. Domestic pulse pneumatic valve working pressure Angle of pneumatic valve and pneumatic valve is. - 。 MPa and flooded pneumatic valve is. - 。 MPa。 Now there are a lot of domestic well-known brands of electromagnetic pulse pneumatic valve manufacturers, significant of nine years recommended CCTV brand list are lit brand electromagnetic pulse pneumatic valve, belonging to hebei nine is lit dust removal equipment co. , LTD. , research and development production.

the technical requirements for electromagnetic pulse pneumatic valve nine is lit brand electromagnetic pulse pneumatic valve on the technical requirements of the products is very strict, its technical requirements and conform to the requirements of the industry standard. Under the following conditions, electromagnetic pulse pneumatic valve should be able to work properly:
( The environment temperature for - - ℃, no corrosive medium in the ambient air.
( Appearance: the surface embalmed, no paint layer peeling, crack, burr, sign clear text.
( Air condition: air pressure is zero. - 。 MPa。 As the temperature - air medium ℃, after oil removal, in addition to water treatment, filtration precision for level 3 of the clean gas pressure can be adjusted.
( Protection grade conform to IP.
( Open voltage in on-line working air pressure state, no more than % of the nominal voltage value.
( Close air supply ability. In the condition of air pressure is off work, electrical signal disappears, electromagnetic pulse pneumatic valve shall be normally closed immediately.
( Open the response time. In the condition of maximum working air pressure, electrical signal voltage values as the standard, the width is not more than. S is pneumatic valve should be able to normally open.
( Compression performance. Should bear. MPa pressure without leakage.
( Insulation: electromagnetic pulse pneumatic valve coil insulation resistance should not be less than M Ω of enclosure. The electromagnetic coil of casing pressure.
( Electromagnetic loop performance: without air condition, the input not greater than % of the nominal voltage value, armature shall promptly absorb diaphragm, signal disappears, armature should be immediately released.
( Vibration resistance: can bear for Hz frequency, the amplitude of mm, the seismic behavior of the last min.
( The service life of the diaphragm: under prescribed conditions, cumulative injection is not less than ten thousand times.
