Description
Technical field
The utility model is related to blast furnace ironmaking field, belongs to the servicing unit of blast furnace cooling stave, particularly a kind of blast furnace cold
But the pressure testing device of wall.
Background technology
Blast furnace cooling stave is the important cooling device of blast furnace lining, installed in the shaft of blast furnace, furnace bosh, bosh, cupola well etc.
Position, not only bears high temperature, the erosion of abrasion, slag and washing away for Gas Flow also subject to furnace charge, it is necessary to possess good heat
The combination properties such as intensity, heat shock resistance, anti-rapid heat cycle.Cooling wall can effectively prevent that furnace shell is heated and burns red, in blast furnace
Cooling wall is protected mainly by slag crust in itself, and maintain the safety in production of blast furnace after lining brick is ablated.Therefore, cooling wall is in a pre-installation
Quality testing be just particularly important, especially the seal tightness test of inner water tube more seems of crucial importance.
Utility model content
The purpose of this utility model is to provide a kind of pressure testing device of blast furnace cooling stave, and its is rational in infrastructure, can be cold
But wall detects the mass defect of cooling wall before installing, and judges the sealing of the water pipe of cooling wall, can improve the peace of cooling wall
Packing quality, improves stove inspection speed.
What the purpose of this utility model was realized in：A kind of pressure testing device of blast furnace cooling stave, in the suitable for reading of support tube
Upper affixed circular support lid, covers in support and sets centre bore and periphery screw, periphery screw away from the support lid center of circle away from
It is equal from the central diameter of cooling wall water pipe tube wall, coordinate on the tube wall of support tube in radial equipartition screw and support tube spiral shell is installed
Bolt；Cooling wall water pipe it is suitable for reading on coordinate to be installed with and be inlaid with the female cap of sealing gasket, water inlet pipe is set on female cap,
Support ligament to coordinate to be arranged on cooling wall water pipe, the centre bore of water inlet pipe from support lid stretches out, in the uniform screw of support tube
The support tube bolt of installation holds out against the water pipe of cooling wall, and the support bonnet bolt installed in the screw of support lid periphery withstands spill
Lid, passes through sealing gasket and cooling wall water pipe ferrule.
The utility model is mainly made up of water pipe gland and cylinder support frame.
Water pipe gland is assemblied by female cap, sealing gasket, water inlet pipe.
Cylinder support frame is main to be made up of support tube and support lid.Uniform 4 in radial circumference direction, the middle part of support tube
Hole, each hole side welding inner thread device nut, the diameter in each hole is slightly larger than the internal diameter of nut, it is ensured that bolt can coordinate with nut
Smoothly penetrated afterwards by each hole, to withstand cooling wall water pipe.Support lid is made by the enough steel plates of intensity, circular, circumference soldering
In support tube top, circle center drilling, central point is overlapped with cooling wall centre of conduit, and aperture is slightly larger than the external diameter of water inlet pipe, really
Protect water inlet pipe upper and lower displacement in aperture.Bolt is covered with the Distance positioning support at the tube wall center of cooling wall water pipe to its center of circle
The distance for entering tube wall center to its center of circle of the center in hole, i.e. cooling wall water pipe enters the distance phase in hole with support lid center and bolt
Deng.Bolt enters hole uniform 3 according to radial circumference direction.Each hole upper weld inner thread device nut, the diameter in each hole is bigger
In the internal diameter of nut, it is ensured that bolt is smoothly penetrated after can coordinating with nut by each hole, to hold out against female cap.
Sealing gasket is inlaid into female cap, and the inlets even of seal and cooling wall water pipe is sealed and coordinated.
The circle center drilling of cylinder support frame, by the insertion of water inlet pipe, water inlet pipe upper and lower displacement in aperture, central point with
Cooling wall centre of conduit overlaps.Screw thread dress is welded on uniform 4 holes in radial circumference direction in the middle part of cylinder support frame support tube
Precession bolt in nut is put, cooling wall water pipe is withstood, and to hold out against.Support lid upper bolt is worn after can coordinating with nut by each hole
Enter, hold out against female cap, female cap compresses seal simultaneously, and the import of seal and but wall water pipe is acted on by thrust, closely
Sealing, reaches the effect of No leakage.
Using the utility model to cooling wall hammering after, improve cooling wall installation quality, accelerate blast furnace maintenance speed, carry
High pressure testing efficiency, it is ensured that repair quality, it is ensured that prolonging campaign.
The utility model is rational in infrastructure, and the mass defect of cooling wall is detected before cooling wall installation, cooling wall is judged
The sealing of water pipe, improves the installation quality of cooling wall, improves stove inspection speed.
