Abstract
The utility model provides a kind of pipe joint structure for pressure test, it is related to pipeline engineering technical field, including upper press ring, gland and lower pressure ring, the upper press ring is fastened at pipe joint with the pushing ring and both ends are bolted, gland is equipped in the upper press ring, the gland is set to the top of Saddle on pipeline.The utility model is highly-safe, the test period is short, saves material and funds, the pipe joint suitable for different size.
Description
Technical field
The utility model belongs to pipeline engineering technical field, and in particular to a kind of pipe joint structure for pressure test.
Background technique
Transport pipeline route is long, and library of standing is more, is completely connected closely, the monitoring on the spot of not only need to stand library and route, but also needs
The telemetry and telecommand of all fronts.The main task of pipe monitoring is: collecting, the operating status of processing, display and record pipe-line system
And technological parameter；By transportation program, dynamic operation condition analysis as a result, selection optimized operation scheme；Assist dispatcher rapidly and accurately
Ground controlled valve and start and stop equipment, to realize selected conveying process flow；Adjust the operating parameters such as flow, pressure and temperature；
Prediction, analysis and processing accident；Carry out oil, gas handover and the account clearing etc. of inception point, terminus and point defeated station.
Each connector of sealing pipeline after pipeline is laid with, tries the Saddle and branch pipe that connect on pipeline, pipeline
Pressure.Part instrument is connected and sealed with instrument with Saddle by welding, since the pressure of pressure testing is apparently higher than just
Normal operating pressure then needs to realize sealing otherwise in the position of instrument in pressure testing to protect test instrumentation.Branch pipe
Platform sealing is generally welded pipe cap using flange seal or on branch pipe and is sealed, and removes after pressure testing.But there are following for this method
Disadvantage:
1, since pressure test pressure is higher, the defect of existing seal-weld will lead to some potential safety problems.
It 2,, cannot be using welding pipe cap due to having strict demand to its face size for part instrument Saddle
Mode seals, and construction site condition is severe, is unable to reach size requirement.
Therefore be badly in need of providing it is a kind of it is highly-safe, the test period is short, saves material and funds, the pipe suitable for different size
The pressure testing sealing frock of road connector.
Utility model content
The purpose of this utility model is the deficiency for existing pipe joint structure for pressure test, provides a kind of highly-safe, examination
Test the period is short, save material and funds, suitable for different size pipe joint pressure testing sealing frock.
The utility model provides the following technical solution:
A kind of pipe joint structure for pressure test, including upper press ring, gland and lower pressure ring, the upper press ring and the pushing latch closure
It closes at pipe joint and both ends is bolted, gland is equipped in the upper press ring, the gland is set to branch pipe on pipeline
The top of platform.
Preferably, the inside of the upper press ring is equipped with notch, and the shape of the notch cross section is rectangle, and the notch is opened
Mouth is at the pipe joint.
Preferably, the notch top is equipped with the gland, the shape of the gland cross section and the notch cross section
Shape it is consistent and be close to notch upper wall.
Preferably, the material of the gland be PTFE, the gland be compacted with the Saddle when being bonded can be formed it is soft
Sealing.
Preferably, the both ends of the upper press ring are equipped with the boss for placing the bolt.
Preferably, the boss is equipped with the threaded hole matched with the bolt with the both ends of the lower pressure ring, passes through rotation
The tight bolt reduces the distance between the upper press ring and the lower pressure ring, so that the gland is compacted with the Saddle
Fitting, and formed and sealed with pipe joint end face.
The beneficial effects of the utility model are:
(1) upper press ring of tooling and lower pressure ring do not need welding end socket by being bolted before pressure testing, try in pressure
It does not need to cut away end socket and again bevel after testing, the test period can be shortened, save expense.
(2) screwing bolts reduce the upper press ring of tooling at a distance from lower pressure ring, sealing pipeline connector end face, gland bottom
It is bonded to form soft seal with the Saddle of pipeline compression, which is suitable for the pipe joint of different size, saves material, is not necessarily to
Weld seam reduces security risk.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention and illustrates.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of the utility model；
Fig. 3 is the enlarged structure schematic diagram of gland in Fig. 2.
In the figure, it is marked as 1, pipeline；2, upper press ring；3, lower pressure ring；4, gland；5, bolt；6, Saddle；7, boss.
Specific embodiment
As shown in Figure 1 to Figure 3, a kind of pipe joint structure for pressure test, including upper press ring 2, gland 4 and lower pressure ring 3, upper press ring
2 are fastened on 1 joint of pipeline with lower pressure ring 3 and both ends are fixed by bolt 5, gland 4 are equipped in upper press ring 2, gland 4, which is set to, manages
The top of Saddle 6 on road 1.
The inside of upper press ring 2 is equipped with notch, and the shape of notch cross section is rectangle, and gap opened is in 1 joint of pipeline.It lacks
Mouth top is equipped with gland 4, and the shape of 4 cross section of gland is consistent with the shape of notch cross section and is close to notch upper wall.Gland 4
Material is PTFE.The both ends of upper press ring 2 are equipped with the boss 7 for placing bolt 5.The both ends of boss 7 and lower pressure ring 3 are equipped with and bolt 5
The threaded hole matched reduces the distance between upper press ring 2 and lower pressure ring 3 by screwing bolts 5, so that gland 4 and Saddle 6
It is compacted fitting, and is formed and is sealed with 1 connector end face of pipeline.
The usage mode of the utility model are as follows: when installation, the upper press ring 2 of tooling is fastened on to the top of pipeline 1, so that on
Gland 4 in pressure ring 2 is located at the top of Saddle 6, and lower pressure ring 3 is fastened on to the lower end of pipeline 1, so that upper press ring 2 and pushing
The threaded hole at 3 both ends of ring is corresponding, fixed by bolt 5.When carrying out pressure testing, makes upper press ring 2 by screwing bolts 5 and push
The distance of ring 3 reduces, and 1 connector of sealing pipeline, gland 4 is compacted with Saddle to be bonded to form soft seal, fluid be full of pipeline 1 and
The Saddle 6 of connection, No leakage in pressure maintaining period.After removal pressure, bolt 5 is unscrewed, loosens and remove upper press ring 2 and lower pressure ring
3.
