Axis has slanted angle, and slanted angle is 45 °.
The above-mentioned device that accurate leakage detection is carried out to blast furnace tuyere small sleeve, it also has potassium permanganate reagent bottle, potassium permanganate examination
Agent bottle is placed in drain valve, and potassium permanganate powder is filled in potassium permanganate reagent bottle, is had on the body of potassium permanganate reagent bottle
Body opening.
A kind of leakage inspection method using above-mentioned tuyere small sleeve leak detection device, it is carried out using following steps：
A. the ball valve of inlet pipeline is closed, is unsnaped into water pipe clamping head, will connected after water inlet pipe clamping head front connector, water inlet pipe clamping head
Fitting respectively by it is preceding to silk, after to silk with water inlet pipe clamping head two ends be connected, drain valve is connected into before water pipe clamping head
Between connector, water inlet pipe clamping head rear connectors；
B. the drain valve cock plug of drain valve is opened；
C. load potassium permanganate reagent bottle in the mouth of pipe for opening drain valve cock plug, then drain valve cock plug is screwed on, close
Close drain valve；
D. inlet pipeline ball valve is opened, slowly be discharged into potassium permanganate in drain valve by the body opening of potassium permanganate reagent bottle
In inlet pipeline；
E. observation tuyere small sleeve, if the water for oozing out changes color, can be identified as adding permanganic acid with the middle gap for covering and contacting
The tuyere small sleeve leak of potassium.
The leakage inspection method of above-mentioned tuyere small sleeve leak detection device, it is found that after tuyere small sleeve has water leakage fault, observe and find
Tuyere small sleeve has oozing out a little for color water, and this oozes out the leakage point for being a little tuyere small sleeve.
The present invention is advantageous in that：
Tuyere small sleeve leak detection device of the invention is dissolved in the characteristic of water discoloration using potassium permanganate, can become from the color of water seepage
Change determine leak small set, leakage detection visual result and it is accurate.Tuyere small sleeve leak detection device simple structure of the invention, operation side
Just, rapid, testing result is detected accurately and reliably, while make easy, it is cheap.
Tuyere small sleeve leakage inspection method of the invention can enable blast furnace staff to the rapid leakage detection of blast furnace tuyere small sleeve
Take corresponding control measure.
The present invention is pioneering in blast furnace tuyere small sleeve Technology of Leak-checking by Gas, is not only solved with simple detection means and method
The long-term problem for judging whether leak for not obtaining effectively solving, also overcomes and be difficult in the prior art accurately to leakage set positioning
Problem, to production have very positive practical function, be worth popularization and application in industry.
