Abstract
The utility model belongs to the technical field of hydrostatic test devices and discloses a cooling-wall hydrostatic test tool. The cooling-wall hydrostatic test tool is technically characterized by comprising a screw provided with a through hole in the center. An outer wall of the screw is provided with a lower locking nut, rubber seal sleeves and an upper locking nut, wherein a lower steel cushion is arranged between the lower locking nut and the rubber seal sleeves, an upper steel cushion and a thrust bearing are arranged between the rubber seal sleeves and the upper locking nut, the number of the rubber sealing sleeves is one, two or more than two. The cooling-wall hydrostatic test tool has low requirements for water pipe end faces and the water pipe end faces just need to meet requirements of drawing allowance. The cooling-wall hydrostatic test tool has the advantages of being simple in structure, reliable in sealing, free of repeated regulation, convenient to mount and dismount, high in working efficiency, and time-saving and labor-saving.
Description
Technical field
The utility model belongs to the water test unit technical field, relates in particular to a kind of cooling wall hydraulic pressure test fixture.
Background technology
One of Key Quality Indicator of blast furnace cooling stave is that interior casting cooling water pipe is non-leakage under the pressure of design.Every blast furnace cold is wall but, and port needs the hundreds of piece, and big stove needs thousands of, and big blast furnace cooling stave cooling water pipe design mostly for bassoon advance to have more steel pipe more, the work pressure test amount is very big.Current cooling wall hydraulic pressure test fixture with rubbery flat gasket shutoff steel pipe port, compresses the mouth of pipe thereby move downward generation pipe axial force by screw thread.This cooling wall hydraulic pressure test fixture requires cooling wall cooling water pipe cross dimensions precision high, otherwise rubber cushion is poorly sealed, causes seepage, needs repeated multiple times adjustment, and complex structure, and loading and unloading are wasted time and energy, inefficiency.
The utility model content
The technical matters that the utility model will solve just provide a kind of to the water pipe end face require low, simple in structure, sealing is reliable, need not to adjust repeatedly, easy to loading and unloading, high efficiency, time saving and energy saving cooling wall hydraulic pressure test fixture.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: comprise that the center is the screw rod of through hole, the outer wall of said screw rod is provided with down locknut, rubber sealing boot and last locknut.
Its additional technical feature is: described locknut down and rubber seal inner room are provided with down the steel pad, are provided with steel pad and thrust bearing between rubber sealing boot and last locknut; Described rubber sealing boot is one, two or more a plurality of.
When the cooling wall hydraulic pressure test fixture that the utility model provided uses; With the center is the screw rod insertion cooling wall cooling water pipe of through hole, and spiro rod rear end is connected with device for detecting water pressure, turns locknut then; Make locknut push rubber sealing boot downwards; The rubber sealing boot good springiness that natural rubber constitutes, under locknut down and last locknut effect, expanding closely contacts with cooling wall cooling water pipe inwall, reaches sealing effectiveness.After treating the rubber sealing boot good seal cooling wall cooling water pipe mouth of pipe, the water filling and detect hydraulic pressure and sealing in the cooling wall cooling water pipe of the central through hole of device for detecting water pressure through screw rod.The cooling wall hydraulic pressure test fixture that the utility model provided requires low to the water pipe end face, as long as meet the drawing tolerance, it is simple in structure, sealing is reliable, need not to adjust repeatedly, easy to loading and unloading, high efficiency, time saving and energy saving.And steel pad, last two steel pads of steel pad are set down, and both played the fixedly effect of rubber sealing boot, bear down the last downforce of locknut and last locknut again, make rubber sealing boot stressed evenly, expansion effect is good.Thrust bearing is set, can reduces the friction force on rubber sealing boot top, prolong the serviceable life of rubber sealing boot.As required, rubber sealing boot can be one, two or more a plurality of, a plurality of rubber sealing boot assemblings, and which rubber sealing boot has been broken, and can change at any time, reduces use cost.
Description of drawings
Fig. 1 is the structural representation of the utility model cooling wall hydraulic pressure test fixture.
Embodiment
Explain further details below in conjunction with the concrete structure and the use principle of accompanying drawing to the cooling wall hydraulic pressure test fixture that the utility model provided.
As shown in Figure 1; The cooling wall hydraulic pressure test fixture that the utility model provided comprises screw rod 1; Screw rod 1 center is a through hole 2, and the outer wall of screw rod 1 is provided with down locknut 3, following steel pad 4, rubber sealing boot 5, goes up steel pad 6, thrust bearing 7, goes up locknut 8, and rubber sealing boot 5 can be a plurality of like what scheme.
When the cooling wall hydraulic pressure test fixture that the utility model provided uses; With the center is the screw rod 1 insertion cooling wall cooling water pipe 9 of through hole 2, and screw rod 1 rear end is connected with device for detecting water pressure, turns locknut 8 then; Make locknut 8 extruding rubber sealing boot 5 downwards; Rubber sealing boot 5 good springiness that natural rubber constitutes, under descending locknut 3 and last locknut 8 acts on, expanding closely contacts with cooling wall cooling water pipe 9 inwalls, reaches sealing effectiveness.After treating rubber sealing boot 5 good seal cooling wall cooling water pipes 9 mouths of pipe, the water filling and detect hydraulic pressure and sealing in cooling wall cooling water pipe 9 of the central through hole 2 of device for detecting water pressure through screw rod 1.And steel pad 4, last 6 two steel pads of steel pad are set down, and both played the fixedly effect of rubber sealing boot 5, bear down the last downforce of locknut 3 and last locknut 8 again, make rubber sealing boot 5 stressed even, expansion effect is good.Thrust bearing 7 is set, can reduces the friction force on rubber sealing boot 5 tops, prolong the serviceable life of rubber sealing boot 5.As required, rubber sealing boot 5 can be one, two or more a plurality of, a plurality of rubber sealing boot 5 assemblings, and which rubber sealing boot 5 is bad, can change at any time, reduces use cost.
Claims (3)
