Description

Oil-gas pipeline protection device
Technical field
The present invention relates to a kind of pipe protection instrument, specifically a kind of oil-gas pipeline protection device.
Background technology
The rational mode of movement of the resources economies such as oil, natural gas and water is to use pipeline, with development of resources Accelerate, the speed of pipe-line construction is also developed rapidly, pipeline maintenance work is also more and more frequent.Pipeline is constructed or it in urban construction It is damaged generation leakage, corrosive pipeline during his fortuitous event to leak, one is to cause environmental pollution, one is resource by wave in vain Take, economic loss is also inestimable.
At present, occur leakage for pipeline to repair, the processing mode of use is the valve closed on pipeline, Yi Zhongshi Pipeline is directly changed, this mode wastes very big to pipeline, causes cost to increase in itself, and because pipeline is commonly located at more Remote area, the time for changing pipeline is general longer, loss can be brought to pipe downstream user, such as resident is cut off the water, stopped the supple of gas or steam, The production such as chemical plant, oil plant is stopped；Another is that the pipe cutting of leakage is fallen, then welds the preceding paragraph pipeline, this Mode can also bring loss to pipe downstream user, and such as resident is cut off the water, stopped the supple of gas or steam, and the production such as chemical plant, oil plant is stopped.Such as What reduces the waste that leakage pollution on the environment and resource occur for pipeline, while reducing pipeline owner and pipeline user Economic loss, is the technical barrier that those skilled in the art thirst for solving always and never solved.
The content of the invention
In view of the above-mentioned problems of the prior art, the present invention provides a kind of oil-gas pipeline protection device, can be quick Leakage point is contained, effect is contained good.
To achieve these goals, the technical solution adopted by the present invention is：A kind of oil-gas pipeline protection device, including preceding pressure Tight end sub-assembly and rear compression end sub-assembly, described preceding compression end sub-assembly and rear compression end sub-assembly are connected with some mutual The compressing unit of connection, described compressing unit includes the compression seat mechanism being symmetrically installed, symmetrical two compress seat mechanism it Between there is connector, have in the middle of described connector through hole and by connecting shaft be arranged on symmetrical two compress seat mechanisms it Between,
Described preceding compression end sub-assembly includes cylinder connector, and the two ends of cylinder connector have two compressions respectively There is spacing, spacing is the width of single compressing member, and the top at the two ends of cylinder connector is solid respectively between part, two compressing members Surely there is a connection rack,
Described rear compression end sub-assembly includes back segment connecting shaft, and the two ends of back segment connecting shaft are provided with rack tube, rack Set is used cooperatively with being connected rack, and the side at the two ends of back segment connecting shaft is further fixed on projection, and projection has hinge hole；
Described preceding compression end sub-assembly, rear compression end sub-assembly and compressing unit bottom is mounted on sealing strip, sealing The width of bar is 1-4 centimetres, and described sealing strip is quality of rubber materials.
The present invention is formed by preceding compression end sub-assembly and rear compression end sub-assembly and the compressing unit of some interconnections One complete attachment means, is closed by rack tube with being connected the closure formation one that rack is used cooperatively to complete whole device Crack progress of the protective of conjunction to pipeline is interim to be contained, and compressing unit each other is to be hinged, and passes through varying number Compressing unit change the length of whole protection device, to adapt to the pipeline of different-diameter, accommodation is bigger.
