Abstract
An inner blockage device for cleaning a low-ignition-point material pipeline belongs to the technical field of material pipelines. The inner blockage device mainly solves the technical problems that when a low-ignition-point material pipeline is partially reconfigured, the reconfiguration engineering of the existing low-ignition point material pipeline to be cleaned is very difficult, and a large quantity of waste low-ignition-point materials is generated. The inner blockage device comprises a piston capable of matching with the inner wall of the low-ignition-point material pipeline and a piston pull rod with one end connected with the piston, wherein a sealing ring is arranged on the circumferential direction of the piston. When the low-ignition-point material pipeline needs to be partially configured, the inner blockage device is used to block low-ignition-point materials in a part of pipeline needing not to be configured, so that when the low-ignition-point material pipeline is partially configured, only the isolated part of the pipeline needs to be cleaned, therefor, the engineering difficulty is reduced when the material pipeline is configured, and the waste low-ignition-point materials generated in the reconfiguration of the material pipeline are reduced.
Description
Technical field
The utility model relates to the material pipe technical field, specifically a kind of interior block apparatus that is used to clean low flame point material pipe.
Background technique
At present, when low flame point material pipe is carried out reconfiguration, at first want the low flame point material in the emptying whole pipe, again whole pipe is cleaned, just can cut off and dock operation when confirming not have in the pipeline low flame point material at last, promptly carry out the operation of pipeline reconfiguration pipeline.Yet, because the length of low flame point material pipe is generally longer, described material pipe reconfiguration method will be cleaned whole pipe, and low flame point material content in the detection whole pipe, so not only exist pipeline reconfiguration engineering difficulty bigger, long shortcoming consuming time is cleaned a large amount of low reluctant drawback of flame point waste material that produces after the whole pipe but also exist.
Summary of the invention
The purpose of this utility model is to provide a kind of interior block apparatus that is used to clean low flame point material pipe at above-mentioned deficiency, in pipeline reconfiguration method, use the engineering difficulty when block apparatus has reduced the material pipe reconfiguration in this, reduced the low flame point waste material that produces in the material pipe reconfiguration process.
The utility model is achieved in that it comprises the piston that can match with low flame point material pipe inwall, the piston pulling rod that an end is connected with piston, and wherein, piston is circumferentially with seal ring.
Block apparatus also comprises the blind lid of flange that is provided with piston pulling rod through hole and flexible pipe through hole in described.
The other end of said piston pulling rod is provided with the piston pulling rod handle.
Advantage of the present utility model is: use this device when low flame point material pipe needs reconfiguration, can block the low flame point material that does not need in the reconfiguration section of tubing, make when hanging down flame point material pipe reconfiguration, only need segregate local pipeline is carried out cleaning, engineering difficulty when having reduced the material pipe reconfiguration has reduced the low flame point waste material that the material pipe reconfiguration produces.

Embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Embodiment: comprise the piston 1 that can match with low flame point material pipe 8 inwalls, the blind lid 4 of piston pulling rod 2, flange that an end is connected with piston 1, wherein, the other end of piston pulling rod 2 is provided with piston pulling rod handle 7, piston 1 is circumferentially with seal ring 3, the blind lid 4 of flange is provided with piston pulling rod through hole 5 and flexible pipe through hole 6, promptly becomes model utility.
The low flame point material pipe that mixes with polyatomic alcohol polybasic alcohol and ring second pentane is that example illustrates using method of the present utility model below, and it comprises the steps:
Low flame point material in the low flame point material pipe 8 of step 1) backflow (be about to ducted low flame point material and flow out, make the low flame point material of nothing in the pipe);
Step 2) cuts off the plan docking site of pipeline, form the new mouth of pipe;
Step 3) is pressed into the piston 1 of band seal ring 3 from the mouth of pipe in pipeline, and the position that piston 1 is moved to meet welding operation safety requirement distance in pipeline (be the piston 1 shown in Figure 1 L that cut off face to low flame point material pipe 8 apart from);
The step 4) water cleans a segment pipe of 1 position from the mouth of pipe to piston, removes the low flame point material residue in this segment pipe;
Step 4.1) is blown into nitrogen in the segment pipe that Xiang Jingshui cleaned, remaining low flame point material residue is blown out;
Step 4.2) the low flame point material content in the segment pipe of detection 1 position from the mouth of pipe to piston.
Step 5) is wrapped up wet towel on low flame point material pipe 8, after needing the end face mounting flange of reconfiguration, low flame point material pipe 8 detects the low flame point material content in the segment pipe from the mouth of pipe to the piston position once more, when the content of low flame point material is lower than the specified value of welding operation safety in production, flange is welded on the mouth of pipe of pipeline.
Step 5.1) the blind lid 4 of flange that has flexible pipe through hole 6 is installed in sealing on flange, by flexible pipe through hole 6 nitrogen injection in pipeline, detects the sealing condition of the welding portion between flange and the pipeline;
Step 5.2) after the welding portion between detection flange and the pipeline does not have gap leakage, pulls down the blind lid 4 of flange.
Step 5.3) the reconfiguration mouth of pipe of another pipeline of correspondence is installed and welded flange, and detected the sealing condition of the welding portion between flange and the pipeline, guarantee that the welding portion between flange and the pipeline does not have gap leakage.
Step 6) is extracted piston 1 out by piston pulling rod 2 and piston rod handle 7, and low flame point material pipe 8 docks the low flame point material pipe of another root by flange, finishes the reconfiguration of low flame point material pipe.
For the above-mentioned L distance of mentioning, transmission of heat when promptly low flame point material pipe welds is converted into the distance of normal temperature, this apart from guarantee follow-up on low flame point material pipe the welded flange and the low flame point material that can not ignite when docking pipeline and be isolated by piston 1, diameter according to low flame point material pipe, the thermal conductivity of the material of low flame point material pipe, the kind of low flame point material, can calculate the distance of solder joint (being the mouth of pipe) to piston, diameter as low flame point material pipe is 70mm, the material of low flame point material pipe is steel, when low flame point material was pentane, above-mentioned L distance was 0.5m.
