Description

Gas pipeline leakage experimental study device
Technical field
Natural gas testing device is the utility model is related to, specially a kind of natural gas line leakage experimental study device.
Background technology
At present, during natural gas tube is defeated, due to a variety of causes, pipeline leakage accident occurs often, when accident occurs When, it is a very important task accurately to determine leakage point and leak condition, currently, on gas pipeline leakage point with And the theoretical research of leak condition is very more, but there is the situation that precision is inadequate in practical application, therefore establish simulation Leak scene carries out experimental study, is a kind of important method.
The content of the invention
The purpose of this utility model is to provide a kind of natural gas line leakage experimental study device, completes natural gas line and exists Under high-pressure delivery state in the case of diverse location, different size, different medium leak condition experimental study.
The utility model adopts the following technical scheme that realization:
A kind of gas pipeline leakage experimental study device, including steel pipe, steel pipe one end connection breather pipe, other end connection Escape pipe, the breather pipe connect booster pump, controlled valve are mounted on the breather pipe and escape pipe;The steel pipe is not The different test leak holes in aperture are distributed with position, control valve, the test leak holes are installed in the test leak holes External flowmeter and installation pressure sensor.
During experiment, using high-pressure pump, day hot gas or other gases are injected in the natural gas line steel pipe of simulation, by It is cumulative to be depressed into stabilization, under pressure plateau, open the control valve for testing leak holes mounted in advance, simulation on steel pipe Natural gas leaking state, by flowmeter and pressure sensor, the gas flow and leakage point pressure under different pore size are determined, Different test leak holes are opened in pass, repeat to test, and study the leakage dotted state under diverse location.
The beneficial effects of the utility model are can to measure natural gas line diverse location, no under high-pressure delivery state Leak condition parameter in the case of same size, different medium.
Brief description of the drawings
Fig. 1 represents structural representation of the present utility model.
In figure, 1- steel pipes, 2- booster pumps, 3- breather pipes, 4- escape pipes, 5- test leak holes, 6- pressure sensors.
Embodiment
Specific embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.
A kind of gas pipeline leakage experimental study device, it is simulation natural gas line different positions under high-pressure delivery state Put, in the case of different size, different medium leak condition research device.As shown in figure 1, including steel pipe 1, as simulation day Right feed channel, the one end of steel pipe 1 connection breather pipe 3, other end connection escape pipe 4, the breather pipe 3 connects booster pump 2, described logical Controlled valve is mounted on tracheae 3 and escape pipe 4;The different test leakage in aperture is distributed with the different parts of the steel pipe 1 Hole 5, the interior installation control valve of test leak holes 5, the test 5 external flowmeter of leak holes(Flow is not drawn into Fig. 1 Meter)And installation pressure sensor 6.
During experiment, using high-pressure pump, day hot gas or other gases are injected in the natural gas line steel pipe of simulation, by It is cumulative to be depressed into stabilization, under pressure plateau, open the control valve for testing leak holes mounted in advance, simulation on steel pipe Natural gas leaking state, by flowmeter and pressure sensor, determine the gas flow and leakage point pressure under different pore size. The pore size of leak holes can be controlled by control valve, such as in the range of 1-5mm, or other scopes.Guan Kai Different test leak holes, repeat to test, and study the leakage dotted state under diverse location.
It should be noted last that above example is only unrestricted to illustrate the technical solution of the utility model, to the greatest extent Pipe is described in detail with reference to the utility model embodiment, it will be understood by those within the art that, it is new to this practicality The technical scheme of type is modified or equivalent substitution, without departure from the spirit and scope of the technical solution of the utility model, its It all should cover in claims.
