Description
Technical field
The present invention relates to industrial pipeline installing area, specifically a kind of plug for pipeline pressure test.
Background technique
Under normal circumstances, it needs to carry out it pressure testing inspection, traditional pressure test process one after the prefabricated installation of industrial pipeline
As using production plug or the blank flange that matches, and welded with the inlet and outlet of pressure testing pipeline, then connect pressure testing dress
Carry out pressure testing is set, also needs to carry out cutting polishing to the plug or blank flange that connect with pipeline after the completion of pressure testing, process is opposite
Cumbersome, interchangeability is inadequate, and traditional pressure test process not only needs pressure testing personnel also to put into welder and wlding, and entire pressure testing period
Also relatively long.
Summary of the invention
It is an object of the invention to overcome drawbacks described above, provides and a kind of for pipeline pressure test and be able to achieve the stifled of fast assembling-disassembling
Head.
In order to achieve the above object, the present invention is implemented as follows:
A kind of plug for pipeline pressure test, including outer end cap, elastic inner supporting circle, pawl assembly, sealing ring, connection bolt, embrace
Hoop and wirerope, wherein outer end cap is set on elastic inner supporting circle, and pawl assembly is arranged in elastic inner supporting circle, and sealing ring is arranged
On elastic inner support ring outer wall；The outside of outer end cap is arranged in connection bolt, and the elastic inner supporting circle with sealing ring is filled in pipe
In road port, support internal pawl component gradually greatly, to make sealing ring and pipeline elastic inner supporting circle by rotating outer end cap
Inner wall is bonded and realizes sealing, and anchor ear is set in the port of pipeline, will connect bolt by wirerope and connect with anchor ear.
The plug for pipeline pressure test, further includes quick coupling, and the quick coupling is arranged on outer end cap simultaneously
And its outlet end is stretched out from elastic inner supporting circle.
The application method of the plug, including
Step 1 prepares plug according to the pipe diameter of required pressure testing；
Plug is arranged in step 2 at pipeline open port；And be engaged by the pawl of plug with inner wall of the pipe compression, it blocks up simultaneously
Sealing ring and tube wall on plug device, which fit closely, prevents leak；
Step 3 installs a dismountable quick coupling and valve in the joint of blocking,
Quick coupling and valve and hydraulic test pump are attached by step 4 by hose, form complete a set of pipeline pressure test pipe
Road.
This plug makes elastic inner supporting circle be adapted to the similar pipeline of caliber by pawl assembly, in this way, comparing tradition
Test can save a large amount of preparation of construction time for needing to prepare a variety of different size plugs or blank flange in the process, and
And the purpose of fast quick-detach is also able to achieve after the completion of test, to accelerate the test efficiency of pressure test.
Detailed description of the invention
Fig. 1 is the cross-sectional view of this plug.
Specific embodiment
The present invention is further illustrated below by way of specific embodiment.
As shown in Figure 1, a kind of plug for pipeline pressure test, including it is outer end cap 1, elastic inner supporting circle 2, pawl assembly, close
Seal 3, connection bolt 4, anchor ear and wirerope, wherein outer end cap 1 is set on elastic inner supporting circle 2, and pawl assembly is arranged in elasticity
In inner supporting circle, sealing ring 3 is set on elastic 2 outer wall of inner supporting circle；The outside of outer end cap 1 is arranged in connection bolt 4, will have close
The elastic inner supporting circle 2 of seal 3 is filled in pipe end, makes internal pawl component gradually by elastic inner support by rotating outer end cap 1
2 support of circle is big, to make sealing ring 3 be bonded with inner wall of the pipe and realize sealing, anchor ear is set in the port of pipeline, passes through wirerope
Connection bolt is connected with anchor ear.
The plug for pipeline pressure test, further includes quick coupling, and the quick coupling is arranged on outer end cap simultaneously
And its outlet end is stretched out from elastic inner supporting circle.
The application method of the plug, including
Step 1 prepares plug according to the pipe diameter of required pressure testing；
Plug is arranged in step 2 at pipeline open port；And be engaged by the pawl of plug with inner wall of the pipe compression, it blocks up simultaneously
Sealing ring and tube wall on plug device, which fit closely, prevents leak；
Step 3 installs a dismountable quick coupling and valve in the joint of blocking,
Quick coupling and valve and hydraulic test pump are attached by step 4 by hose, form complete a set of pipeline pressure test pipe
Road.
This plug makes elastic inner supporting circle be adapted to the similar pipeline of caliber by pawl assembly, in this way, comparing tradition
Test can save a large amount of preparation of construction time for needing to prepare a variety of different size plugs or blank flange in the process, and
And the purpose of fast quick-detach is also able to achieve after the completion of test, to accelerate the test efficiency of pressure test.
