The air supply pipe in the air supply component is connected to the communicating hole on the stator plate. The air supply component fills the communicating hole with gas through the air supply pipe, and a pressure gauge and flow meter are used to monitor the pressure and flow of the injected gas in real time. The adjuster rotates the adjustment lever to adjust the force applied by the adjustment lever to the adjustment column, thereby adjusting the opening of the regulating valve located in the communicating hole so that the gas flow in the communicating hole meets the requirements. Thus, when using the present invention's stator plate flow adjustment fixture to adjust the flow rate of the communicating hole on the stator plate, only the adjustment lever needs to be rotated, making the adjustment simple, convenient, and quick.

Further preferably, a limiting member is provided on the support plate, and the limiting member includes a limiting column and a limiting pressure plate, the limiting column is fixed on the support plate, and the limiting pressure plate is located at the free end of the limiting column and above the positioning groove. In this way, during the adjustment process, the limiting pressure plate on the limiting member can be used to press the static disc, so that the static disc is fixed in the positioning groove, thereby preventing the static disc from shifting during the adjustment process and affecting the adjustment efficiency and adjustment effect.
[0008] Preferably, the static disk flow adjustment tool includes an air supply bracket, which includes a support column and a support frame. The support column is located on the side of the bracket, and the support frame is installed on the support column and is located above the bracket.

[0012] Next, combine Figures 1 to 3 , the static disc flow adjustment tooling of the utility model is described in detail.
[0013] like Figure 1-3As shown, the static disc flow adjustment tool of the present invention includes a support, an adjustment member, and an air supply member. The support includes a bracket 11 and a positioning seat 12. The positioning seat 12 is located at the top of the bracket 11 and is provided with a positioning groove 121 and an adjustment through-hole 122. The adjustment member includes an adjustment column 21 and an adjustment pressure rod 22. The adjustment column 21 is inserted into the adjustment through-hole 122. The positioning end of the adjustment pressure rod 22 is mounted on the bottom of the positioning seat 12 via a connecting pin 23, and the middle of the adjustment pressure rod 22 is located below the adjustment column 21. The air supply member includes an air supply pipe (not shown in the figure), and the air supply pipe is provided with a pressure gauge 31 and a flow meter 32. Preferably, the positioning seat 12 includes a support plate 123, which is mounted and fixed on the top of the bracket 11. This can improve the stability of the positioning seat 12 on the bracket 11 and prevent the positioning seat 12 from being misplaced on the bracket 11, thereby affecting the adjustment efficiency and effect. Preferably, a receiving groove 1231 is provided at the bottom of the support plate 123, and the connecting pin 23 is installed on the side walls of the receiving groove 1231. The adjusting pressure rod 22 is located in the receiving groove 1231. This makes it convenient to install the adjusting pressure rod 22 and to position the adjusting pressure rod 22 when assembling the static disc flow adjustment tooling of the present invention. Preferably, a limiting member 124 is provided on the support plate 123. The limiting member 124 includes a limiting column 1241 and a limiting pressure plate 1242. The limiting column 1241 is fixed to the support plate 123, and the limiting pressure plate 1242 is located at the free end of the limiting column 1241 and above the positioning groove 121. In this way, during the adjustment process, the limiting pressure plate 1242 on the limiting member 124 can be used to press the static disc 4, so that the static disc 4 is fixed in the positioning groove 121, thereby preventing the static disc 4 from shifting during the adjustment process and affecting the adjustment efficiency and adjustment effect.
[0014] like Figure 1-3As shown, the adjustment member also includes an adjustment link 24 and an adjustment disk 25. The positioning end of the adjustment link 24 is mounted on the positioning seat 12, and the free end of the adjustment link 24 passes through an adjustment slide hole 221 on the adjustment pressure rod 22. The adjustment disk 25 is mounted on the free end of the adjustment link 24 and is threadedly connected to the adjustment link 24. This allows the adjuster to adjust the flow rate in the communicating hole 41 of the stator plate 4 by simply turning the adjustment disk 25 to move the adjustment pressure rod 22 along the adjustment link 24 toward or away from the positioning seat 12, making operation simple and convenient. Preferably, the adjustment slide hole 221 is located near the free end of the adjustment pressure rod 22. This allows the adjustment slide hole 221 to be farther from the connecting pin 23, reducing the effort required during adjustment and the workload of the adjuster. Preferably, a rotating handle (not shown) is provided on the adjustment disk 25. This allows the adjuster to adjust the flow rate by simply turning the rotating handle, further reducing the workload of the adjuster. Preferably, a rotating handle hole 251 for inserting a rotating handle rod is provided on the side of the adjustment disk 25. In this way, when adjusting, the adjuster can insert the rotating handle rod into the appropriate rotating handle hole 251 according to the adjustment needs, which can reduce the weight of the turntable 25 and facilitate the adjustment of the adjuster.
[0015] like Figure 1-3 As shown, the stator flow adjustment tool of the present invention also includes an air supply bracket, which includes a support column 51 and a support frame 52. The support column 51 is located on the side of the bracket 11, and the support frame 52 is installed on the support column 51 and is located above the bracket 11. In this way, the air supply bracket can be used to support the air supply components and the pressure gauge 31 and flow meter 32 for real-time monitoring, so that the adjustment personnel can read the air pressure and flow data of the gas filled in the connecting hole 41 on the stator 4 in a timely manner during the adjustment process, thereby improving the adjustment accuracy of the stator flow. Preferably, the support frame 52 includes a support gripper 521, and the support gripper 521 is provided with a clamping groove 5211 for clamping the air supply component. In this way, using the support gripper 521 with the clamping groove 5211 to clamp the air supply component is convenient for assembly and convenient for users to replace the air supply component according to adjustment needs, which is convenient to use.
[0016] When using the stator plate flow adjustment tool of the present invention to adjust the flow rate of the communication hole on the stator plate, the stator plate 4 is installed in the positioning groove 121 on the positioning seat 12. The air supply pipe in the air supply component is connected to the communication hole 41 on the stator plate 4. The air supply component fills the communication hole 41 with gas through the air supply pipe, and the pressure and flow rate of the injected gas are monitored in real time using a pressure gauge 31 and a flow meter 32. When the flow rate is low, the adjuster rotates the adjusting pressure rod 22 so that the free end of the adjusting pressure rod 22 rotates away from the positioning seat 12, thereby reducing the force applied by the adjusting pressure rod 22 to the plug 421 in the regulating valve (not shown) located in the communication hole 41 and increasing the opening of the regulating valve. When the flow rate is low, the adjuster rotates the adjusting pressure rod 22 so that the free end of the adjusting pressure rod 22 rotates toward the positioning seat 12, thereby increasing the force applied by the adjusting pressure rod 22 to the plug 421 in the regulating valve and decreasing the opening of the regulating valve. It can be seen that when the flow rate of the communicating hole 41 on the stator plate 4 is adjusted by using the stator plate flow rate adjustment tool of the present invention, it is only necessary to rotate the adjustment lever 22 , and the adjustment is simple, convenient and quick.
