The beneficial effects of the present invention are:
The present invention provides a kind of inner flow passage detecting tool of turborotor, and structure is simple, novel, passes through entirety
Structure design, the sustainable stable negotiability to turborotor inner flow passage detect.Pass through institute on water inlet pipe
If pressure stabilizing cavity, can make water flow in water inlet pipe that there is a more stable pressure, and can by external water flow test lead,
It learns water flow data at this time, if it is unstable data occur, needs to detect whether there is the case where leakage, and excluded,
If there is not leak case, and multiple drainage hole water outlet status on detected turborotor are bad, then illustrate quilt
The negotiability of the turborotor inner flow passage of detection is unqualified, is unable to meet demand；Inside pressure stabilizing link block
The caliber of water stream channel is less than the caliber of the water inlet pipe, therefore can be by pressure stabilizing link block, so that inside pressure stabilizing link block
Water stream channel leads to the water of turborotor inner flow passage not there is a situation where cutout and throttles, and reduces to the effect for influencing experiment
Fruit reduces influence factor；By the clamping mode of the first U-shaped folder, the second U-shaped folder, reduces and the sight of tested part is blocked,
Facilitate observation and judgement, and convenient for mounting and clamping.

Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
As shown in Figures 1 to 3, the present invention provides a kind of inner flow passage detecting tool of turborotor, including water inlet pipe
1, one end of pressure stabilizing link block 2, curved surface sealing plate 3, pressing plate 4, the water inlet pipe 1 is equipped with pressure stabilizing cavity 5, and the end passes through locking nut
The nozzle of water stream channel inside the 6 connections pressure stabilizing link block 2, the pressure stabilizing link block 2 recline described in curved surface sealing plate 3
Back side, the curved surface sealing plate 3 is equipped with through its back side and inboard circulation groove 7, the circulation groove 7 and pressure stabilizing link block 2
Internal water stream channel communicates, and the pressing plate 4 is positioned close to the inboard side of curved surface sealing plate 3, the pressing plate 4 and curved surface sealing plate
Detected turborotor 8, a wherein end-plate at detected 8 both ends of turborotor are installed between 3 inboards
Be bonded with the curved surface sealing plate 3, and between the two be equipped with gasket 9, the side seal board of detected turborotor 8 with
Between curved surface sealing plate 3 and pressure stabilizing link block 2 by the first U-shaped folder 10 clamp locking, detected turborotor 8 it is another
End-plate is bonded with the pressing plate 4, and also is provided with gasket 9 between the two, and clamps locking using the second U-shaped folder 11, described
Detected 8 inner flow passage of turborotor is with the cooperation of circulation groove 7 on curved surface sealing plate 3 and inside communicates.
It is connect with the hose 12 communicated inside it with external water flow test lead on the pressure stabilizing cavity 5 by connection.
It is equipped with locking in first U-shaped folder 10, the second U-shaped folder 11 and adjusts bolt 13.
Multiple drainage holes 14 are equipped on the detected turborotor 8.
The caliber of water stream channel inside the pressure stabilizing link block 2 is less than the caliber of the water inlet pipe 1, and pressure stabilizing may make to connect
It connects the water stream channel inside block 2 to lead to the water of 8 inner flow passage of turborotor not there is a situation where cutout and throttle, reduction pair
The effect of experiment is influenced, influence factor is reduced.
Comprehensive technical solution of the present invention, structure is simple, novel, by overall construction design, sustainable stable pair
The negotiability of 8 inner flow passage of turborotor is detected.By pressure stabilizing cavity 5 set on water inlet pipe 1, water inlet pipe can be made
Water flow in 1 has a more stable pressure, and can learn water flow number at this time by external water flow test lead
According to, if it is unstable data occur, need to detect whether there is the case where leakage, and excluded, if there is not leak case,
And 14 water outlet status of multiple drainage holes on detected turborotor 8 is bad, then illustrates detected turbine directing vane
The negotiability of 8 inner flow passage of piece is unqualified, is unable to meet demand；Due to the caliber of the water stream channel inside pressure stabilizing link block 2
Less than the caliber of the water inlet pipe 1, therefore can be by pressure stabilizing link block 2, so that the water stream channel inside pressure stabilizing link block 2 leads to
The water of 8 inner flow passage of turborotor is reduced to the effect for influencing experiment, reducing influences not there is a situation where cutout and throttling
Factor；By the clamping mode of the first U-shaped folder 10, the second U-shaped folder 11, reduce and the sight of tested part is blocked, facilitates sight
It examines and judges, and is convenient for mounting and clamping.
