Embodiment 1

[0031] Such as Figure 1-3 As shown, the anti-vibration pressure equalizing pipe of the water turbine includes an expansion joint 5, a pipe body 7 and a radial anti-vibration connector for connecting with the lining flange 4, the expansion joint 5 is fixedly connected with the pipe body 7, and the The radial anti-vibration connector is arranged on the expansion joint 5 .

[0032] When the water turbine unit is running, the water turbine unit vibrates, and the pipe body 7 also vibrates and moves axially and radially. Since the expansion joint 5 provided on the pipe body 7 has the function of expanding and contracting along the length direction of the pipe body 7, the expansion joint 5 One end of the expansion joint 5 is fixed on the pipe body 7 and expands and contracts back and forth correspondingly with the vibration. The other end of the expansion joint 5 is provided with a radial anti-vibration connector, and the end of the expansion joint 5 arranged in the radial anti-vibr...

Embodiment 2

[0034] Such as Figure 1-3 As shown, the anti-vibration pressure equalizing pipe of the water turbine includes an expansion joint 5, a pipe body 7 and a radial anti-vibration connector for connecting with the lining flange 4, the expansion joint 5 is fixedly connected with the pipe body 7, and the The radial anti-vibration connector is arranged on the expansion joint 5 .

[0035] The radial anti-vibration connector includes a connection flange and a support ring 3, the support ring 3 is fixed on the expansion joint 5, the support ring 3 is assembled on the connection flange, and the radial anti-vibration connector passes through The connecting flange is connected with the lining flange 4.

[0036] The connecting flange includes a supporting flange 1 and a supporting ring matching flange one 2, the supporting flange 1 and supporting ring matching flange one 2 are connected together, and a groove 8 is provided, and the supporting ring 3 is assembled In the groove 8 , there is ...

Embodiment 3

[0041] Such as Figure 1-3 As shown, the anti-vibration pressure equalizing pipe of the water turbine includes an expansion joint 5, a pipe body 7 and a radial anti-vibration connector for connecting with the lining flange 4, the expansion joint 5 is fixedly connected with the pipe body 7, and the The radial anti-vibration connector is arranged on the expansion joint 5 .

[0042] The radial anti-vibration connector includes a connection flange and a support ring 3, the support ring 3 is fixed on the expansion joint 5, the support ring 3 is assembled on the connection flange, and the radial anti-vibration connector passes through The connecting flange is connected with the lining flange 4.

[0043] The connecting flange includes a supporting flange 1 and a supporting ring matching flange one 2, the supporting flange 1 and supporting ring matching flange one 2 are connected together, and a groove 8 is provided, and the supporting ring 3 is assembled In the groove 8 , there is ...

Abstract

The invention relates to a vibration-preventing equalizer pipe of a water turbine. The vibration-preventing equalizer pipe comprises an expansion joint, a pipe body and a radial vibration-preventing connecting piece used for being connected with a lining flange. The expansion joint is fixedly connected with the pipe body, and the radial vibration-preventing connecting piece is arranged on the expansion joint. According to the vibration-preventing equalizer pipe, the expansion joint is arranged on the pipe body and the radial vibration-preventing connecting piece is arranged on the expansion joint, so that the expansion joint connected with the pipe body has the functions that the expansion joint extends and retracts in the length direction of the pipe body and swings in the section direction of a pipe opening of the pipe body during vibration, direct hard connection between the pipe body and equipment is avoided, and centralized stress generated on the pipe body is scattered; and accordingly, the situation that water leaks due to the fact that the pipe body is broken by vibration is prevented, accidents are avoided, and the safety coefficient is increased.
