Application of vibration aging technology in different types of normally open solenoid valves

Vibration aging technology is a very common technology in the solenoid valve series, in many places play an important role in different solenoid valve is a different performance, which is also explained in this issue for you.

1, the working principle of the normally open vibration direct-acting solenoid valve

In the billet processing and cutting process, the internal residual stress of the workpiece will appear, which leads to instability of the workpiece, thus affecting the mechanical properties and dimensional stability of the parts. Vibrating high temperature ball valve is a method to eliminate the residual stress inside the metal parts by tapping. Under the action of cyclic external force, three five usually open solenoid valve workpiece produced a co-vibration, co-vibration in the cross-transformation stress and the residual stress accumulated inside the workpiece, with the passage of time, the local deformation of the workpiece, so that the grain boundaries and grain boundaries move, atoms from the high stability of the potential energy transfer to a lower potential energy. Through this process, the macroscopic residual stresses of the workpiece can be migrated, reduced and homogenized, so that the residual stresses inside the workpiece can be reduced or eliminated.

2、The working principle of high temperature vibration normally open solenoid valve device

High-temperature piston type normally open solenoid valve vibration analysis device consists of exciter, control host, acceleration sensor, support rubber and other components. Its main role is to control the exciter in a specific excitation, the exciter in a specific frequency (speed) range to operate with higher stability frequency accuracy. Especially when the resonance peak before and after the load characteristics change more significantly, recorded, identified and derived the curve and parameters about the direct gas solenoid valve.

3, the development of high temperature normally open solenoid valve

The effect of the use of vibrating high-temperature solenoid valve is related to its chosen process. It is a kind of forging with strong rigidity, rough surface, uneven thickness, high residual stress and complex structure. From 2005, a company introduced vibrating purple copper normally closed solenoid valve, has made great progress so far. According to years of production practice, it is pointed out that: the manufacturing process of vibrating type is more complex, it needs to be vibration pretreatment, and improve its vibration performance through reasonable vibration parameters.
