Description
Technical field
The present invention relates to sealing tool technical field in the water pressure test, the hydraulic pressure plugging device of a kind of pipe joint.
Background technology
During boiler product manufactures, pressurized assembly is required for greatly carrying out the test of sealing property after completing, and mostly is note
Water pressurizes, to being required at module outlet block.Method pipe joint being blocked to general employing has: swollen plug closure,
Place the closure of process allowance sealing plate, outer hoop is swollen plug closure etc..Pipe joint diameter be there are certain requirements, according to hydraulic pressure by swollen plug closure
Test pressure size, typically can not be the biggest；For placing the closure of process allowance welding equipment shrouding, need after hydraulic pressure completes
Except the operation such as surplus bevel, if the location comparison that pipe joint is on assembly is special or bevel shape is more special,
Subsequent handling compare difficulty.Special, as shown in Figure 1 and Figure 2 compared with big and position or groove type for pipe joint caliber
, existing do not have reasonable method for blocking and device.
Summary of the invention
In order to solve the problems referred to above, the invention provides the hydraulic pressure plugging device of a kind of pipe joint, it is capable of bigger
Caliber and position or the special pipe joint closure of groove type, applied widely and simple and reliable, low cost, sealing effectiveness is high.
Its technical scheme is such that the hydraulic pressure plugging device of a kind of pipe joint, it is characterised in that it include sealing plate and
Pressing plate, described platen support is in pipe joint outside opening, and described sealing plate is arranged at described pipe joint inside opening, described pressing plate
It is connected by pull bar with described sealing plate, after the tension of described pull bar, makes described sealing plate block described pipe joint inside opening and make
Described pressing plate compresses and is supported in described pipe joint outside opening.
It is further characterized by, and is provided with seal washer between described sealing plate and described pipe joint inside opening；
Described seal washer is metal washer, and described metal washer excircle dimension is identical with described pipe joint external diameter, described metal
Packing ring inner circle is smaller in size than described internal diameter of pipe joint；
Outer, described sealing plate side has the packing ring step coordinated with described seal washer, and described sealing plate opposite side is provided with
Chamfering；
Described pressing plate is Y shape plate, and three feet of described Y shape plate are supported in described pipe joint outside opening end face；
Described pull bar threaded one end connects the blind hole on described sealing plate, and the described pull bar other end is through the screw thread on described pressing plate
Through hole and pass through nut check；
It is provided with lifting bolt on described pressing plate and described sealing plate.
After using the structure of the present invention, owing to have employed pressing plate and sealing plate so that for pipe diameter size and position or
Groove not requirement, after being connected by pull bar and strained, sealing plate can be effectively realized the closure of pipe joint, platen support in
It is reliable that pipe joint external interface realizes Stability Analysis of Structures, and overall structure is simple, and low cost is applied widely；It is provided with seal washer
After packing ring step, may further ensure that sealing effectiveness, after pressing plate uses Y shape plate so that while its simple in construction, support
Compress reliable for effect.
Accompanying drawing explanation
Fig. 1 is product structure front view；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is present configuration schematic diagram；
Fig. 4 is pressure plate structure top view.
Detailed description of the invention
Seeing Fig. 3, shown in Fig. 4, the hydraulic pressure plugging device of a kind of pipe joint, it includes sealing plate 1 and pressing plate 2, and pressing plate 2 supports
In pipe joint 3 outside opening, sealing plate 1 is arranged at pipe joint 3 inside opening, and pressing plate 2 is connected by pull bar 4 with sealing plate 1, draws
Make sealing plate 1 plugging pipe joint 3 inside opening after bar 4 tension and make pressing plate 2 compression be supported in pipe joint 3 outside opening.
Being provided with seal washer 5 between sealing plate 1 and pipe joint 3 inside opening, seal washer 5 uses metal washer, can
To extend its service life, metal washer excircle dimension is identical with pipe joint 3 external diameter, and metal washer inner circle is smaller in size than pipe joint
3 internal diameters；Outer, sealing plate 1 side has the packing ring step coordinated with seal washer 4, and sealing plate 1 opposite side is provided with chamfering；Pressure
Plate 2 is Y shape plate, and three feet of Y shape plate are supported in pipe joint 3 outside opening end face；Pull bar 104 threaded one end connects sealing plate 1
On blind hole, pull bar 4 other end is locked through the tapped through hole on pressing plate 2 and by nut 6 and pad 7；Pressing plate 2 and sealing plate
Lifting bolt 8 it is provided with on 1.
Installation process is as described below: sealing plate 1, seal washer 5, pull bar 4 and lifting bolt 8 are filled at drum manhole 9
Enter below drum 10 inner tube joint 3, check that pipe joint 3 lower flat has impulse-free robustness etc. affect the factor of sealing property and disappear
Remove, seal washer 5 be placed in the packing ring step of sealing plate 1 after spinning pull bar 4 make pull bar 4 screw thread seam face be adjacent to sealing plate 1,
Lifting bolt 8 assembling put in place, from pipe joint 3 endoporus lift sealing plate 1, the outer rear flank of pull bar 3 protruded tube joint 3 assemble pressing plate 2 and
Lifting bolt 7 is also fixed with pad 7, nut 6, checks sealing plate 1 and pipe joint 3 lower flat and cylindrical laminating in screwing operations
Situation, seal washer 5 circumference is the most uniformly compressed.
