Three - way machine classification introduction

Three - way machine classification introduction

Three - way machine is the production of three - way machine, three - way refers to the metal three - way, whether carbon steel, alloy steel, stainless steel, and titanium alloy of the company's production of three - way machine can be produced.There are generally three kinds of three-way machine, hot drawing three-way machine, hot pressing three-way machine, cold extrusion three-way machine.

Hot drawing tee machine is characterized by low cost, but the pull out outlet is not high enough, and a section of steel pipe needs to be welded.

The hot press tee machine this process is first in order to produce a tee with a larger wall thickness than CSH80.

Cold extrusion tee machine, is also the most commonly used tee production method, now the production scale is 1/2(21mm)-24(630mm), thickness is SCH80, it is characterized by high efficiency, low defect rate, reasonable price, generally a molding.

Three - way machine solenoid valve introduction

Three - way machine is mainly divided into two three - way solenoid valve is normally closed type one is normally open type two.Normally closed type refers to the coil is not energized when the gas circuit is broken, normally open type refers to the coil is not energized when the gas circuit is through.Normally closed two 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, which is equivalent to the point of action.Normally open two three single electrically controlled solenoid valve action principle: to the coil power, 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 road is connected (the positive action air outlet is gas), even if the positive action coil power is still connected to the positive action gas road, will always be maintained to resist the coil electric stop.When the resistance coil is energized, the resistance gas circuit is connected (the resistance gas hole has air). Even after the resistance coil is energized, the resistance gas circuit is still connected and will remain until the positive action coil is stopped.This is tantamount to self-locking.Two three - way solenoid valves are usually one - in - two - out series.There is also the saying of normally open and closed.Solenoid valve three ports are A-B-C port, there are also B to C port.Normally closed type is the solenoid valve power, the valve is closed, normally closed type.In other words, it cannot exit port A
