Description
Technical field
A kind of blast furnace cooling stave pressure testing device of the utility model, belongs to the pressure testing device technology neck of blast furnace cooling wall
Domain.
Background technology
Usually require to set cooling wall in the furnace wall of blast furnace, cooling wall is by rectangle fragment of brick and is cast into its internal bending
Cooling water pipe constitute.During cooling, realized by injecting cooling water into water pipe, so the Key Quality of blast furnace cooling stave refers to
One of mark is exactly that interior casting cooling water pipe is non-leakage under the pressure of design.
And a blast furnace cooling wall has hundreds of pieces, or even thousands of pieces, and big cooling water pipe of cooling wall of blast furnace design is big
Mostly to enter to have more, work pressure test amount is very big more.Current cooling wall hydraulic pressure structure for pressure test, is to block port of steel pipe with rubber ring,
Move downward generation pipe axial force to compress the mouth of pipe using screw thread.This cooling wall hydraulic pressure structure for pressure test requires that cooling wall is cold
But water pipe cross dimensions precision is high, and otherwise rubber cushion is poorly sealed, causes seepage, it is necessary to which repeated multiple times be adjusted, and structure is multiple
It is miscellaneous, load and unload bothersome laborious, inefficiency.
Utility model content
The utility model overcomes prior art presence not enough, and there is provided a kind of low to water pipe end face requirement, structure letter
List, sealed reliable, the blast furnace cooling stave water pressure test work high, time saving and energy saving without adjustment, easy to loading and unloading, operating efficiency repeatedly
Dress.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of blast furnace cooling stave pressure testing dress
Put, including screw rod, rubber sealing boot, locking cover and upper locknut, the lower end of the screw rod is fixedly installed flange, the screw rod band
Have in one end insertion cooling water pipe of flange, the rubber sealing boot is sleeved on screw rod, and with locking cover by rubber sealing boot
Be buckled in cooling water pipe, the locking cover is that bottom is provided with the groove-like structure of through hole, the through hole is used to interting screw rod, it is described on
Locknut is screwed on screw rod, and locking cover is fastened on cooling water pipe.
The outer wall dimension of the rubber sealing boot and the inner wall size of cooling water pipe are mutually matched adaptation.
The quantity of the rubber sealing boot is one, or is multiple.
The screw rod is hollow screw.
The utility model has an advantageous effect in that compared with prior art：Cooling wall hydraulic pressure provided by the utility model
Test tool to water pipe end face require it is low, its simple in construction, sealed reliable, without repeatedly adjustment, easy to loading and unloading, operating efficiency
Height, it is time saving and energy saving, it is easy to maintenance.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure：1 it is screw rod, 2 be rubber sealing boot, 3 be locking cover, 4 be upper locknut, 5 be flange, 6 is cooling water pipe.
Embodiment
As shown in figure 1, a kind of blast furnace cooling stave pressure testing device of the utility model, including screw rod 1, rubber sealing boot 2, locking
Cover 3 and upper locknut 4, the lower end of the screw rod 1 are fixedly installed flange 5, one end insertion cooling of the screw rod 1 with flange 5
In water pipe 6, the rubber sealing boot 2 is sleeved on screw rod 1, and rubber sealing boot 2 is buckled in cooling water pipe 6 with locking cover 3,
The locking cover 3 is the groove-like structure that bottom is provided with through hole, and the through hole is used to intert screw rod 1, and the upper locknut 4 is screwed in spiral shell
On bar 1, locking cover 3 is fastened on cooling water pipe 6.
The outer wall dimension of the rubber sealing boot 2 is mutually matched adaptation with the inner wall size of cooling water pipe 6.
The quantity of the rubber sealing boot 2 is one, or is multiple.
The screw rod 1 is hollow screw.
Operation principle of the present utility model：In hydraulic pressure test fixture in use, screw rod 1, rubber sealing boot 2 are inserted into cooling
In wall cooling water pipe 6, its frock free state is positioned on water pipe, then turn locknut 4, be pressed down against locknut 4
Rubber sealing boot 2, because the elasticity of rubber sealing boot 2 is good, in the case where upper locknut 4 is acted on bottom mounting flange 5, expansion is cold with cooling wall
But the inwall of water pipe 6 is in close contact, and reaches sealing effectiveness.Outside is fastened with bolt again, making will not be because of pressure in its process of the test
And come off or pressure release.
Cooling wall hydraulic pressure test fixture provided by the utility model requires low to water pipe end face, and simple in construction, sealing can
Lean on, without repeatedly adjustment, easy to loading and unloading, operating efficiency it is high, time saving and energy saving.And upper locknut 4 and bottom mounting flange under setting
5, fixed rubber sealing boot can be played a part of, the pressure of locknut 4 is born again, make the uniform force of rubber sealing boot 2, expanded
Effect is good.And rubber sealing boot 2 can be one, it is two or more multiple, that is broken, and can change at any time, drop
Low use cost.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited to
Embodiment is stated, in the knowledge that those of ordinary skill in the art possess, the utility model objective can also not departed from
On the premise of various changes can be made.
