Electromagnetic reversing pneumatic valve performance is introduced

electromagnetic reversing pneumatic valve is electromagnet of thrust to move the pneumatic valve core movement to transform the direction of fluid flow control of pneumatic valves, solenoid pneumatic valve for short.

electromagnetic reversing pneumatic valve has a sliding pneumatic valve and ball valve two kinds of structures, commonly referred to as electromagnetic reversing pneumatic valve for pneumatic valve structure, called globular or cone electromagnetic reversing pneumatic valve pneumatic valve core for pneumatic valves, solenoid directional also called electromagnetic pneumatic valve ball.

the main performance requirements of the electromagnetic reversing pneumatic valve:

the commutation performance

in the regulation of working conditions, the electric pneumatic valve can reliably when reversing, can reliably when the power is reset. Pressure loss,



electromagnetic reversing pneumatic valve pressure loss of fluid flow through the pneumatic valve solenoid directional pneumatic valve mouth when the flow loss and throttling loss. , within the

leak amount

in electromagnetic reversing pneumatic valve of leak amount refers to the regulation of working conditions, work in different position, from the high pressure cavity to the low pressure cavity of the leak amount.

, reversing and reset time

from the electromagnet electricity to the pneumatic valve core is reversing the time required to terminate, reset time refers to the pneumatic valve core from electromagnetic power to the time required to reply to the initial position.

and the reversing frequency

in unit time allowed by the largest number of commutator

life

use pneumatic valve to the main parts is damaged, cannot be normal commutation and reset action, or to use its main performance index is significantly worse than the index number of commutation rules.

variety of electromagnetic reversing pneumatic valve, according to its working position number and access number of how many can be divided into two three links, two cross, three cross, etc. ; According to the reset and positioning forms can be divided into spring return type, ball position type, no reset spring type; According to the pneumatic valve body and the connection form of electromagnet can be divided into flange connection and threaded connection; According to the distribution of magnet structure can be divided into dry type and wet type, each category has ac, dc, and the whole form, and the required power supply voltage and have a good variety of, so there is much difference in its structure.
