电磁阀原理及2位3通5通（Solenoid valve principle and 2 bit, 3 pass, 5 pass） In the gas (or liquid) to say, two position three way solenoid valve has 1 air inlet (inlet gas) and 1 outlet (giving the target device source), 1 exhaust holes (usually install a silencer, if not afraid of noise you can not install @_@). Two position five way solenoid valve has 1 air inlet (inlet gas), 1 and 1 are moving to make holes to make holes reactionary (which gives a target device against the action of air supply), 1 positive and 1 anti action vent vent (muffler) action. For small automatic control equipment, the trachea is usually made of 8~12mm industrial rubber tube. Solenoid valve generally used in Japan SMC (high point, but a small Japanese products), Taiwan Yadeke (affordable, good quality) or other domestic brands and so on. In electrical terms, two - bit three - way solenoid valve is generally single electric control (that is, single coil), two - bit, five - way solenoid valve is generally double - control (that is, double coil). Coil voltage levels generally use DC24V, AC220V and so on. Two position three way solenoid valve is normally closed and normally open type two, normally closed type refers to the coil is not energized when the road is broken, the normally open type refers to the coil is not energized when the road is. Normally closed type two bit three way solenoid valve action principle: to the coil energized, gas line through, once the coil is switched off, the gas path will be disconnected, which is equivalent to inching.. Normally open type two bit, three way single electronically controlled solenoid valve action principle: to the coil energized, gas path off, once the coil is switched off, the gas path will be connected, and this is inching.. Two position five way double solenoid valve action principle: to action coils are connected (action gas path was made, the porosity gas) even if the action is the coil power action is the gas path is still connected, and will be main
