Present inventor is the study found that it is all in most cases because of Jie for passing through valve body that vibration, which occurs, for valve body
The uniformity of matter is poor or medium when passing through valve body, there are apparent internal differential pressures, in addition, medium generates whirlpool in valve body
Stream can also cause irregular oscillation to a certain extent.
After medium, which has just left flow control section 100, enters rectification section 200, the flowing of medium is more chaotic.Setting is mutually flat
Capable the first rectification channel 210 and third rectification channel 230 can provide enough buffer channels for medium, make the flowing of medium
Become more gentle, stablize.
Medium enters after the first rectification channel 210, and due to shutting off by flow control section 100, media interior pressure reduces, and is situated between
Matter is easier to be rectified.But the flowing for just having entered the medium in the first rectification channel 210 is also more chaotic, is easy to produce unrest

Gentleization with Balancing relization medium flow field is offset, can make medium flow field in rectification section 200 by the second rectification of setting channel 220
It realizes and turns to, by turning to, the certain sinuous flow layers being located in the middle part of medium flow field can be made in rectification projection 225 and transition protrusion 226
Under the action of upset again, and again with the laminated stream of the steady flow of surrounding, realize the thorough rectification to medium flow field.Medium flows through
After crossing the rectification of rectification projection 225 and transition protrusion 226 that outer arc wall at two is arranged in, internal sinuous flow can effectively be subtracted
Weak or elimination, to keep the smoothness of entire medium flow field higher.
It should be noted that since the second rectification channel 220 is by the first segmental arc 221, the second segmental arc 222, third arc
Shape section 223 and the 4th segmental arc 224 are constituted, and entire vias inner walls are smooth gentle, medium flow field can smoothly, smoothly through no
It will cause new sinuous flow to generate.
It is handled by the above rectification means, the medium flow field for eventually entering into non-return section 300 can be made to become very steady, make to be situated between
The fluidized bed of mass flow is stable, mitigates, and effectively reduces irregular impact of the medium flow field to non-return section 300, while reducing medium
Stream makes new-type vibrationproof movable valve 1000 generate a possibility that vibrating and substantially reduces a possibility that non-return section 300 generates sinuous flow.
