| Three - way machine two solenoid valve action principle
Three way solenoid valve action principle: to the coil is energized, the gas circuit is connected, once the coil power, the gas circuit will be disconnected, this is equivalent to the "point".Normally open two three-way single electrically controlled solenoid valve action principle: to the coil, the gas circuit is disconnected, once the coil power, the gas circuit will be connected, this is also the "point".Two five-way double electrically controlled solenoid valve action principle: to the positive action coil is energized, then the positive action gas path is connected (the positive action air outlet hole has gas), even if the positive action coil power is still connected to the positive action gas path, will always be maintained to resist the coil energized stop.If the resistance coil is energized, the resistance gas circuit is connected (the resistance gas hole is energized). Even after the resistance coil is energized, the resistance gas circuit is still connected and will remain energized until the positive action coil is energized and stopped.This amounts to "self-locking".Two three - way solenoid valves are usually one - in - two - out series.There is also a saying that often open often closed.Solenoid valve three ports are A\B\C three ports, usually A to B or A to C port, there are B to C port.Normally closed type is the solenoid valve power off in the future, the valve is closed, normally closed.In other words, it cannot exit port A.
Two three-way solenoid valve is divided into normally closed and normally open two types, normally closed refers to the coil is not energized when the gas road is broken, normally open refers to the coil is not energized when the gas road is through
Tee machine is how to produce tee pipe fittings: tee machine technology is leading the straight tube with water crowded into three links, reduce lead, lead blank, drilling, retreat lead process, save cost and production time, in order to guarantee the stability of water pressure, we use transformer to stability of equilibrium in copper pipe extrusion tee water pressure, make the copper tube in the extrusion process maintain a constant pressure;Both sides of the cylinder to adjust the synchronization performance, we also use the synchronizer to synchronize the two sides of the cylinder, so as to achieve a higher rate of finished products (can process the diameter of more than 7 mm copper pipe, pass rate of more than 98%, molding cycle of about 10 seconds/time).Tee machine mainly produces carbon steel, stainless steel, alloy steel and other materials of the three-way pipe fittings.Can manufacture 90 degree and 135 degree tee fittings.The above is how the three - way machine regular production of three - way pipe fittings.Tee machine can produce diameter of 21mm-630mm, wall thickness of 3mm-20mm we can produce.
