Description
Technical field
This utility model is related to sealing tool technical field in the water pressure test, the hydraulic pressure closure dress of specially a kind of pipe joint
Put.
Background technology
In boiler product manufacture, pressurized component is required for greatly the test for carrying out sealing property after completing, and mostly notes
Water pressurizes, to being required to block at module outlet.For the general method for adopting of the closure of pipe joint has：Swollen plug closure,
Place process allowance sealing plate closure, outer hoop is swollen plug closure etc..Swollen plug closure is there are certain requirements to pipe joint diameter, according to hydraulic pressure
Test pressure size, typically can not be too big；For the closure of process allowance welding equipment shrouding is placed, need after the completion of hydraulic pressure
Except operations such as surplus bevels, if location comparison of the pipe joint on component is special or bevel shape is more special,
Subsequent handling is compared difficulty.For pipe joint caliber is larger and position or groove type are special, as shown in Figure 1 and Figure 2
, existing without reasonable method for blocking and device.
Content of the invention
In order to solve the above problems, this utility model provides a kind of hydraulic pressure plugging device of pipe joint, and which can be realized
Compared with Large Diameter Pipeline and position or groove type special pipe joint closure, applied widely and simple and reliable, low cost, sealing effect
Fruit is high.
Its technical scheme is such：A kind of hydraulic pressure plugging device of pipe joint, it is characterised in that it include sealing plate and
Pressing plate, in pipe joint outside opening, the sealing plate is arranged at the pipe joint inside opening, the pressing plate to the platen support
It is connected by pull bar with the sealing plate, the pull bar makes the sealing plate block the pipe joint inside opening and make after tensing
The pressing plate is compressed and is supported in the pipe joint outside opening.
Which is further characterized by, and is provided with seal washer between the sealing plate and the pipe joint inside opening；
The seal washer is metal washer, and the metal washer excircle dimension is identical with the pipe joint external diameter, described
Metal washer inner circle is smaller in size than the internal diameter of pipe joint；
Sealing plate side outer is provided with the packing ring step coordinated with the seal washer, and the sealing plate opposite side sets
It is equipped with chamfering；
The pressing plate is Y shape plate, and three feet of the Y shape plate are supported in the pipe joint outside opening end face；
The pull bar threaded one end connects the blind hole on the sealing plate, and the pull bar other end is through on the pressing plate
Tapped through hole and pass through nut check；
Lifting bolt is provided with the pressing plate and the sealing plate.
After using structure of the present utility model, as a result of pressing plate and sealing plate so that for pipe diameter size and position
Put or groove is not required, after being connected and tensed by pull bar, sealing plate can be effectively realized the closure of pipe joint, pressing plate
Supportting and Stability Analysis of Structures reliability being realized in pipe joint external interface, overall structure is simple, and low cost is applied widely；It is provided with sealing
After packing ring and packing ring step, sealing effectiveness is may further ensure that, pressing plate is using after Y shape plate so that while its simple structure,
Support compression effect reliability.

Specific embodiment
See Fig. 3, shown in Fig. 4, a kind of hydraulic pressure plugging device of pipe joint, it include that sealing plate 1 and pressing plate 2, pressing plate 2 are supported
In 3 outside opening of pipe joint, sealing plate 1 is arranged at 3 inside opening of pipe joint, and pressing plate 2 is connected by pull bar 4 with sealing plate 1, draws
Bar 4 makes 1 plugging pipe joint of sealing plate, 3 inside opening after tensing and compresses pressing plate 2 to be supported in 3 outside opening of pipe joint.
Seal washer 5 is provided between 3 inside opening of sealing plate 1 and pipe joint, seal washer 5 adopts metal washer, can
To extend its service life, metal washer excircle dimension is identical with 3 external diameter of pipe joint, and metal washer inner circle is smaller in size than pipe joint
3 internal diameters；1 side outer of sealing plate is provided with the packing ring step coordinated with seal washer 4, and 1 opposite side of sealing plate is provided with chamfering；Pressure
Plate 2 is Y shape plate, and three feet of Y shape plate are supported in 3 outside opening end face of pipe joint；104 threaded one end of pull bar connects sealing plate 1
On blind hole, 4 other end of pull bar 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 is provided with 1.
Installation process is as described below：Sealing plate 1, seal washer 5, pull bar 4 and lifting bolt 8 are filled from drum manhole 9
Enter below 10 inside pipe joint 3 of drum, check that 3 lower flat of pipe joint has impulse- free robustness etc. to affect the factor of sealing property and disappear
Remove, seal washer 5 spinning pull bar 4 makes 4 screw thread seam face of pull bar be adjacent to 1 face of sealing plate after being placed in the packing ring step of sealing plate 1,
Lifting bolt 8 assemble in place, from 3 endoporus of pipe joint lift sealing plate 1, pull bar 3 stretch out on the outside of pipe joint 3 after assemble pressing plate 2 and
Lifting bolt 7 is simultaneously fixed with pad 7, nut 6, checks sealing plate 1 and 3 lower flat of pipe joint and cylindrical fit in screwing operations
Situation, whether seal washer 5 is circumferential is uniformly compressed.
