Što je an elektronički ekspanzija ventil
The electronic expansion valve is a a gas element that can adjust the flow of rashladno sredstvo enter the refrigeration device accord to a preset program.
Gdje je ekspanzija ventil korišteno?
Air conditioners, refrigerators (household and commercial), refrigerators, refrigerated trucks, refrigerated containers), automatic vending machines, environmental test tanks, CO2 water heaters, etc.
Sastav od ekspanzija ventil:
The electronic expansion valve uglavnom sastoji se od dva dijelova: te zavojnica dio i ventil tijelo dio.
Valve body part: The valve body is mainly composed of stainless steel shell, permanent magnet rotor, nut, screw shaft, needle valve, body and connecting pipe. Coil part: the coil is wound on the insulating tube by wires one by one, and the wires are insulated from each other; the winding of the coil part is a double-strand wire.
The control princip of the elektronički ekspanzija ventil:
The rotor the motor usvaja a permanent magnet, and the magnetic attraction or repulsion is generated between the magnetic poles induced by the rotor and the magnetic poles induced by the stator poles induced by the stator winding, so that the rotor rotates. The coil (pulse motor) is controlled by the wire control main board, the main board sends out control commands, applies pulse voltage to the stator winding of the motor, and drives the rotor to move. When the command signal sequence is reversed, the motor rotate in the reverse direction, so the pulse signal can control the forward and reverse rotation of the motor. Turn to make the regulating STEM Move Up Down, Change The Opening of The Valve Needle, i Real Flow Regulation. The maximum opening and minimum opening of The Valve Body are controlled by The Corresponding Limit Mechanism.
Permanent magneti za ekspanzija ventili:
PPS injection mouldding magnet, NdFeB materijal, metal insert mold overmolding, 24-pole magnetized permanent magnet, surface magnetic field strength 1700 Gauss. PPS has good resistance to to terma shocks, and The NdFeB material is otporan to to nisko temperaturno okruženja i will not demagnetize, which Is Why The Expansion Valve does not use ferrite permanent magnets.
