1）改变节流件形状，消除共振法
因电动阀的所谓振源发生在高速流动、压力急剧变化的节流口，改变节流件的形状即可改变振源频率，在共振不强烈时比较容易解决。
2）避开振源波击法
外来振源波击引起阀振动，这显然是电动阀正常工作时所应避开的，如果产生这种振动，应当采取相应的措施 。
3）增大导向尺寸，减小配合间隙法
轴塞形阀一般导向尺寸都较小，所有阀配合间隙一般都较大，有0.4～lmm，这对产生机械振动是有帮助。因此，在发生轻微的机械振动时，可通过增大导向尺寸，减小配合间隙来削弱振动。
4）增加刚度法
对振荡和轻微振动，可增大刚度来消除或减弱，如选用大刚度的弹簧，改用活塞执行机构等办法都是可行的。
5）减小汽蚀振动法
对因空化汽泡破裂而产生的汽蚀振动，自然应在减小空化上想办法。①让气泡破裂产生的冲击能量不作用在固体表面上，特别是阀芯上，而是让液体吸收。套筒阀就具有这个特点，因此可以将轴塞型阀芯改成套筒型。②采取减小空化的一切办法，如增加节流阻力，增大缩流口压力，分级或串联减压等。
6）增加阻尼法
增加阻尼即增加对振动的摩擦，如套筒阀的阀塞可采用“O”形圈密封，采用具有较大摩擦力的石墨填料等，这对消除或减弱轻微的振动还是有一定作用的。
There are several solutions to vibration faults in self operated electric valves:
1) Change the shape of the throttling element and eliminate resonance method
Because the so-called vibration source of electric valves occurs at the throttle port with high-speed flow and rapid pressure changes, changing the shape of the throttle component can change the frequency of the vibration source, which is easier to solve when the resonance is not strong.
2) Avoiding vibration source wave strike method
The vibration of the valve caused by external vibration sources is clearly something that electric valves should avoid during normal operation. If this vibration occurs, corresponding measures should be taken.
3) Increase guide size and reduce fit gap method
The guide size of axial plug valves is generally small, and the clearance between all valves is generally large, ranging from 0.4 to 1mm, which is helpful for generating mechanical vibration. Therefore, when slight mechanical vibration occurs, the vibration can be weakened by increasing the guide size and reducing the fit gap.
4) Increasing stiffness method
For oscillations and slight vibrations, increasing stiffness can be used to eliminate or weaken them, such as selecting springs with high stiffness or switching to piston actuators.
5) Reducing cavitation vibration method
For the cavitation vibration caused by the rupture of cavitation bubbles, it is natural to find ways to reduce cavitation The impact energy generated by bursting bubbles does not act on the solid surface, especially on the valve core, but is absorbed by the liquid. Sleeve valves have this characteristic, so the plug type valve core can be changed to a sleeve type Take all measures to reduce cavitation, such as increasing throttling resistance, increasing the pressure at the constriction port, grading or series pressure reduction, etc.
6) Increase damping method
Increasing damping means increasing friction against vibration. For example, the valve plug of a sleeve valve can be sealed with an "O" ring, and graphite packing with high friction can be used. This can still have a certain effect on eliminating or weakening slight vibrations.
