The principle of solenoid valve operation , Taiwan Ming company presents to you

On the gas line (or fluid line), the two-position three-way solenoid valve has one inlet port (connected to the inlet gas source), one outlet port (provided to the target device gas source), and one vent hole ( A muffler is generally installed. If it is not afraid of noise, it can be installed without @_@).

The 5/2-way solenoid valve has 1 air inlet (intake air source), 1 positive air outlet and 1 counter-action air outlet (one source for each positive and negative air supply to the target device), 1 Positive air vents and 1 reverse air vent (installed muffler).

Taiwan Ming electromagnetic valve For small automatic control equipment, the general selection of 8 ~ 12mm industrial plastic pipe. Electrically speaking, two-position three-way solenoid valves are generally single-electrically controlled (ie, single-coil), and two-position five-way solenoid valves are generally dual-controlled (ie, two-coil). The coil voltage level generally uses DC24V, AC220V and so on. Two-way three-way solenoid valve is divided into normally closed type and normally open type. When the normally closed type finger coil is not energized, the gas line is broken. When the normally open type coil is not energized, the gas line is open.

Normally closed two-position three-way solenoid valve operating principle: power to the coil, gas circuit, once the coil is powered off, the gas will be disconnected, which is equivalent to "jog." Normal open two-position three-way single solenoid valve action principle: power to the coil, the gas circuit is disconnected, once the coil is powered off, the gas circuit will be connected, this is also the "jog" Taiming two five-pass double Control solenoid valve operating principle: When the positive solenoid is energized, the positive actuator air circuit is connected (the positive actuator air outlet is gas), even if the positive actuator air circuit is still connected after the positive operational coil is de-energized, it will be maintained. Until the anti-action coil is energized. When the anti-action coil is energized, the reverse working air circuit is turned on (the reverse operation air outlet has gas). Even if the anti-action air circuit is still turned on after the anti-operation coil is de-energized, it will be maintained until the positive operation coil is energized. . This is equivalent to "self-locking."

Based on this feature of the two-position five-way double solenoid valve, when the electromechanical control loop is programmed or the PLC program is programmed, the solenoid valve coil can be operated for 1~2 seconds, which can protect the solenoid valve coil from damage. .
