Solenoid valve not only can be used in pneumatic systems

Solenoid valve not only can be used in pneumatic systems, hydraulic systems, water pressure system can be the same or similar applications, such as low-power oil small electromagnetic valve, seals do not need to oil discharge the gas does not pollute the environment, can be used for food, medicine, electronics and other industries. As technology continues to progress, the solenoid valve and control technology, computer technology, electronic technology, the combination has been able to carry out a variety of complex control. Such as solenoid valve can be in the field of intelligent control applications in wireless control technology. The solenoid valve is precisely because the electromagnetic control, so it can be a variety of electronic systems to interface, and this is it one of the main reasons of the wide range of applications.


The solenoid valve has been widely applied in various fields of production, with the electromagnetic control technology and manufacturing processes improve, the solenoid valve to achieve a more sophisticated control, pneumatic system, hydraulic system to play its role.


Two three-way solenoid valve is normally associated with single acting pneumatic actuator institutions supporting two controllable two locations: on - off, the three links, there is a three-channel ventilation, a channel with the gas source connection under normal circumstances, the other two channel 1 with the implementing agencies of the air inlet connection, one with the implementing agencies, the exhaust port, specific works can refer to a single acting pneumatic actuator schematic.


Two five-way solenoid valve is usually double-acting pneumatic actuator institutions supporting two controllable two locations: on - off, five have five channel ventilation, in which a connection with the gas source, the two pairs the role of the external air chamber cylinder out of the air inlet connection, one after another out of the air intake of the two internal chamber, specific works can refer to a double acting pneumatic actuator works.


On the gas (or liquid Road), two three-way solenoid valve with an air intake (tap into the gas source) and a vent (air) to the target device, and a vent (usually installed a muffler, not afraid of noise, can not install). Two five-way solenoid valve with an air intake (tap into gas source), a movement out of the air vents and a reactionary to make the pores (respectively a positive and negative actions gas source to the target device), a positive action vent and an anti-action vent (to install the muffler).


For small automatic control equipment, the trachea is generally used in the 8 ~ 12mm industrial glue trachea. In electrical terms, the two three-way solenoid valve generally as a single electronic control (single coil), two five-way solenoid valve is generally double solenoid (coil). Coil voltage levels are generally DC24V, AC220V.


Two three-way solenoid valve is divided into a normally closed and two normally open, normally closed means the coil is not powered gas line is broken, the normally open type refers to the gas path is through the coil not energized. Normally closed two way solenoid valve operation principle: the coil is energized, the gas line connected to the coil power, gas line will be disconnected, which is equivalent to "jog". Often open type two-three links, a single electronically controlled solenoid valve action principle: the coil is energized, the gas line is disconnected, once the coil power outages, gas line will be connected, which is the "jog".


Double electric control, in two five-way solenoid valve action principle: the coil is energized to positive action, positive action gas line connected to the (positive action to vent gas), even if the coil power failure to the positive action and positive action gas is still connected will be maintained until to until the anti-action coil is energized. To the anti-action coil power, gas line connected to the anti-action (to make reactionary stomatal gas), even to the anti-action coil power, the anti-action gas still is connected, will be maintained until the coil is energized to positive action so far .


This is equivalent to "self-locking". Two five-way dual electronically controlled solenoid valve this feature in the design of mechanical and electrical control circuit or the preparation of the PLC program when the solenoid valve coil action 1 ~ 2 seconds, so you can protect the solenoid valve coil is not easily damaged .
