Abstract
The utility model discloses polyethylene double-pipe for chemical industry fluid transportation, and belongs to the technical field of transporting pipelines. The polyethylene double-pipe for chemical industry fluid transportation comprises an inner polyethylene pipe and an outer polyethylene pipe. Polyethylene sealing rings are placed on two ends of the inner polyethylene pipe and on two ends of the outer polyethylene pipe, and the two ends of the inner polyethylene pipe and the two ends of the outer polyethylene pipe are sealed through the polyethylene sealing rings; the inner polyethylene pipe is fixedly placed in the outer polyethylene pipe through a polyethylene supporting ring; and a leakage detection device is placed on the outer polyethylene pipe. Due to the adoption of the technical scheme mentioned above, the outer pipe has certain external pressure resistance and protection functions, and the inner pipe is used for transporting of chemical industry fluid and pressure bearing of the chemical industry fluid. When leaking, the fluid only flows in the outer pipe, and is prevented from leaking to the environment. The detection device on the outer pipe can timely detect liquidation leakage conditions, and eliminate leaked liquid. The inner pipe is matched with the requirements of the chemical industry fluid, the outer pipe is matched with the environment; the supporting ring and the sealing rings are matched with the size of the outer pipe to achieve the requirements for environment protection; the inner pipe and the outer pipe respectively satisfy the requirements of solid wall polyethylene pipes at present, are strong in economy and good in application expanding.

Technical field
The utility model belongs to the conveyance conduit technical field, is specifically related to a kind of good chemical industry fluid conveying of Safety performance two sleeve pipes of polyethylene that leak of liquid detects that can be used for.
Background technique
At present, single sleeve pipe etc. are widely used in the conveying of fluid, as in some specific chemical industry fluids are carried, and the main also still application of single sleeve pipe.The conveying of fluid is paid attention in the design of general single sleeve pipe, and does not do further protection design at the situation that leaks of fluid, tends to cause the pollution of environment.Along with the raising of environmental requirement, the insulation blocking of some chemical industry fluids is needed to strengthen, these fluids are carried should be corrosion-resistant for the requirement of pipeline, again pressure-bearing.And pipeline was carried after operation a period of time, had all multifactor impacts the working life of pipeline, and pipeline often can not be found timely after losing efficacy, and influenced the delivery safety of fluid.
The model utility content
At the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of good chemical industry fluid conveying of Safety performance two sleeve pipes of polyethylene that leak of liquid detects that can be used for.
Described a kind of chemical industry fluid is carried with the two sleeve pipes of polyethylene, comprise pipe and polyethylene outer tube in the polyethylene, it is characterized in that pipe is arranged in the polyethylene outer tube by the polyethylene support ring in the described polyethylene, the termination, two ends of pipe and polyethylene outer tube arranges the polyethylene seal ring in the polyethylene, by the polyethylene seal ring seal, on the described polyethylene outer tube leak detection apparatus is set.
Described a kind of chemical industry fluid is carried with the two sleeve pipes of polyethylene, it is characterized in that arranging at interval on the described polyethylene support ring one group of projection, the round external diameter at the peak place of described projection equals the internal diameter of polyethylene outer tube, and the internal diameter of polyethylene support ring equals the external diameter of pipe in the polyethylene.
Described a kind of chemical industry fluid is carried with the two sleeve pipes of polyethylene, it is characterized in that having mounting hole on the described polyethylene outer tube, and the leak detection apparatus sealing is arranged on the mounting hole.
Described a kind of chemical industry fluid is carried with the two sleeve pipes of polyethylene, it is characterized in that described leak detection apparatus is valve, connects the delivery pipe for delivery of the chemical industry fluid on the valve.
Above-mentioned a kind of chemical industry fluid is carried with the two sleeve pipes of polyethylene, comprise pipe and polyethylene outer tube in the polyethylene, it is characterized in that pipe is fixedly installed in the polyethylene outer tube by the polyethylene support ring in the described polyethylene, the termination, two ends of pipe and polyethylene outer tube arranges the polyethylene seal ring in the polyethylene, by the polyethylene seal ring seal, on the described polyethylene outer tube leak detection apparatus is set.The two sleeve pipes of polyethylene of the present utility model; its outer tube has certain critical external compressive resistance and protective action; interior pipe is used for conveying and the pressure-bearing of chemical industry fluid; when fluid is revealed; only flow on the outer tube, avoid fluid to be leaked in the environment and go, and be furnished with detection device on the outer tube; in time detect the liquefaction leakage situation; and the liquid that leaks can be discharged, pipe cooperates the demand of chemical industry fluid in it, and outer tube cooperates the demand of environment; support ring and seal ring cooperate the size of inner and outer pipes; can satisfy the conveying requirement of fluid, can reach the protection requirement of environment again, inner and outer pipes meets the requirement of present polyethylene solid wall pipe respectively; Economy is strong, expands and uses better.
