Description
Technical field
Originally it is new to be related to petrochemical industry, relate more specifically to a kind of oil and gas pipeline leakage detection instrument.
Background technology
Gas oil pipe leakage accident can cause huge economic loss, the wasting of resources and environmental pollution, even jeopardize sometimes
Life security.The safe and reliable operation in long oil pipeline road is just paid close attention to by more and more from engineering, environment and society.Due to
Corrosive pipeline perforation causes the small-scale leakage of continuation, the discovery early of this leakage caused by pipeline aging or working environment
Be accurately positioned be current oil and gas long distance pipeline leak detection technology problem.At present both at home and abroad for the inspection of long distance pipeline leakage
Survey method mainly has ray method, negative pressure wave method, guided wave technology, remote-controlled robot, active sonar, passive sonar etc..But these sides
The limitation of method all its own applications, ray method can only be detected in the range of localized region, to long range detection speed very
Slowly, take longer;Ultrasound detection climbs machine, Magnetic Flux Leakage Inspecting climbs machine, although ROV detection methods Technical comparing is ripe, its operating efficiency
It is low, it is necessary to detect point by point, or can only discontinuity detected, and be only applicable to no excessive elbow and the pipeline of junction.Cause
This, real time leak detection can be carried out to oil-gas pipeline by being badly in need of a kind of detecting instrument of development.
Utility model content
New content
It is the defects of for prior art, originally new to provide a kind of oil and gas pipeline leakage detection instrument.
A kind of oil and gas pipeline leakage detection instrument, leak detection pipe 6 is fixed with petroleum pipeline 5, is offered on petroleum pipeline 5
One hole, for first hole position in the leak detection pipe 6, leakage detector 8 has a housing 13, is installed in the bottom of housing 13
There is a connecting tube 15, connecting tube 15 is connected with leak detection pipe 6 by screw thread 9, and one end of connecting tube 15 is stretched into housing 13,
An elastic bellows 16 are provided with the inner space 11 of housing 13, one end of elastic bellows 16 is fixed in connecting tube 15,
And connected with connecting tube 15, the other end of elastic bellows 16 is shut, and is provided with an indicating arm 12 thereon, is covered on indicating arm 12
Provided with spring 17, spring 17 is sheathed on indicating arm 12 and between elastic bellows 16 and the top cover 14 of housing 13, is being pushed up
The second hole 14a is offered on lid 14, indicating arm 12 passes from the 14a of second hole.
Optionally, petroleum pipeline 5 is made up of interior corrosion-resistant coating 1, metal level 2 and outer corrosion-resistant coating 3, and metal level 2 is positioned at interior anti-
Between corrosion layer 1 and outer corrosion-resistant coating 3.
Originally new beneficial effect is:This new leakage detector, detected by the change of petroleum pipeline internal pressure
Whether leaked, the generation of leakage can be detected in real time, and more elbows and the pipeline of junction, apparatus structure can be detected
Simply, testing cost is low.
Brief description of the drawings
Fig. 1 is detector first state structural representation;
Fig. 2 is detector the second status architecture schematic diagram.
Embodiment
It is new to this below in conjunction with the accompanying drawings to enable this new above-mentioned purpose, feature and advantage more obvious understandable
Embodiment be described in detail, this new above and other purpose, feature and advantage will be become apparent from.Complete
Identical reference instruction identical part in portion's accompanying drawing.Not deliberately accompanying drawing drawn to scale, it is preferred that emphasis is show that this is new
The purport of type.
As shown in figure 1, this new tubing leak detector is used to detect whether petroleum pipeline 5 leaks, detector peace
Loaded on petroleum pipeline 5, a part for petroleum pipeline 5 is exposed on ground 4, and another part can be embedded under ground 4.Petroleum pipeline 5
Typically a kind of multiple tube, it is made up of interior corrosion-resistant coating 1, metal level 2 and outer corrosion-resistant coating 3, and metal level 2 is located at interior anticorrosion
Between layer 1 and outer corrosion-resistant coating 3, interior corrosion-resistant coating 1 and outer corrosion-resistant coating 3 can be such as rubber layers.It is fixed with petroleum pipeline 5
Leak detection pipe 6, leak detection pipe 6 can be welded on petroleum pipeline 5, and the first hole is offered on petroleum pipeline 5, and first hole position is in institute
State in leak detection pipe 6, leakage detector 8 has a housing 13, and a connecting tube 15, connecting tube are provided with the bottom of housing 13
15 are connected with leak detection pipe 6 by screw thread 9, i.e., when mounted, connecting tube 15 is screwed into leak detection pipe 6 by screw thread 9,
One end of connecting tube 15 is stretched into housing 13, and an elastic bellows 16, elastic wave are provided with the inner space 11 of housing 13
One end of line pipe 16 is fixed in connecting tube 15, and is connected with connecting tube 15, and the other end of elastic bellows 16 is shut, and is pacified thereon
Equipped with an indicating arm 12, spring 17 is arranged with indicating arm 12, spring 17 is located in housing 13, i.e., spring 17 is sheathed on instruction
On bar 12 and between elastic bellows 16 and the top cover 14 of housing 13, the second hole 14a, indicating arm are offered on top cover 14
12 pass from the 14a of second hole.
This Novel work principle is described further with reference to Fig. 1 and Fig. 2.When petroleum pipeline 5 does not leak, its
Internal pressure is larger, and the oil gas in petroleum pipeline enters elastic bellows by the first hole and by leak detection pipe 6, connecting tube 15
In 16, due to not leaking, the pressure in petroleum pipeline 5 is more than the elastic force of spring 17, and spring 17 is compressed, elastic bellows 16
Stretching, extension, indicating arm 12 is ejected from the second hole 14a, as shown in figure 1, when indicating arm 12 is in ejection position, then illustrated defeated
Oil pipe 5 does not leak.When leaking, the internal pressure of petroleum pipeline 5 reduces, and the pressure of spring 17 is more than inside petroleum pipeline 5
Pressure, in the presence of spring 17, elastic bellows 16 are compressed, while in the retraction housing 13 of indicating arm 12, as shown in Fig. 2
After finding that indicating arm 12 is retracted, then illustrate that petroleum pipeline 5 is leaked.This new leakage detector, by petroleum pipeline
The change of portion's pressure detects whether to be leaked, and can detect the generation of leakage in real time, and can detect more elbows and company
The pipeline at place is connect, apparatus structure is simple, and testing cost is low.
It is new in order to fully understand to elaborate many details in the above description.But above description is only
This new preferred embodiment, this it is new can be much different from other manner described here to implement, therefore this
It is new not limited by specific implementation disclosed above.Any those skilled in the art are not departing from this new technique simultaneously
