Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model.
Specific embodiment is as follows:
As shown in Fig. 2, a kind of pipe vibration damper based on flow fieldoptimization include: orifice plate A4 and orifice plate B6, sleeve A3 and
Sleeve B5, gland 7, flange 1, sealing ring 8.
Orifice plate B6 and orifice plate A4 are fixedly mounted in pipeline 2, and orifice plate B6 and orifice plate A4 are both provided with falcon slot, are used for and sleeve
Cooperation, sleeve B5 along 2 inner wall of pipeline be mounted between orifice plate B6 and sleeve A3, the both ends of sleeve B5 respectively with orifice plate B6 and orifice plate
The falcon slot of A4 cooperates, and the falcon slot of the one end sleeve A3 and orifice plate A4 cooperate, and the other end is connect with gland 7, and gland 7 is by whole device pressure
Tightly.Sealing ring 8 is provided between gland 7 and sleeve A3, for managing interior sealing.Whole device is connected to 2 system of pipeline by flange 1
In.
The distance between orifice plate A4 and orifice plate B6 can be by the length adjustments of sleeve B5 and sleeve A3, while cooperating 7 He of gland
Sealing ring 8 realizes sealing in dismounting and pipe.
As shown in fig. 6, orifice plate A4 and orifice plate B6 is six hole of second level, hole is evenly distributed in center circumferential, in actual use,
Aperture, hole count, hole arrangement mode be varied according to the structural parameters and operating parameter of pipe-line system, specific aperture is opened
Hole mode is determined that common hole count n is advisable with 4~7 by Flow Field Calculation.
As shown in figure 4, the effect of gland 7 is to realize the axially position and compression of orifice plate and sleeve, while staying on sealing surface
There are 3 inverted triangle slots to reinforce sealing effect.
As shown in figure 5, sleeve is conveniently detachable, roll adjustment can be facilitated, the barrel dliameter of sleeve, length according to the caliber of pipeline 2 into
Row adjustment.
As shown in Fig. 2, flange is used for connecting pipe vibration absorber and pipe-line system, to reduce the resistance of ducting, a mouthful method of making even
It is blue.
The fluid of pipe vibration damper upstream is when flowing through orifice plate, and by the local resistance of resistance of ducting part, flow field is shunk,
Flow velocity increases, and static pressure reduces, and in pipe vibration damper downstream, flow field is restored, but because of the flow-disturbing of local resistance part, exists certain
Crushing, pressure reduction to design pressure.Due to the disturbance of pipeline local resistance part stream field, lead to pressure fluctuation, velocity fluctuation,
To generate big pipe vibration and noise.The utility model by the principle of step pressure reducing, reduce flow field pressure fluctuation,
Velocity fluctuation, to reduce pipe vibration.
Pressure drop size caused by pipe vibration damper is by the structural parameters such as flow velocity, aperture, hole arrangement mode, grade spacing and fortune
The influence of row parameter.
