Abstract
The utility model discloses a double-layer pressure sealing drainer of special-shaped pipe, which is composed of the following components: a pipe line, a linear pipe, sealing material, a housing and a flange. The linear pipe is equipped at the periphery of a central line of a leakage point of the special-shaped pipe and is fixedly connected with the point of the special-shaped pipe. The periphery of the linear pipe is filled with sealing material. The periphery of the sealing material is provided with a housing pipe. One end of the housing pipe is welded with the special-shaped pipe, and the other end is connected with the flange. According to the utility model, the leakage point of the special-shaped pressure (intermediate pressure, low pressure non-flammable non-explosive medium) pipe is sealed. Compared with the using effect of prior-art pressure leakage stoppage through injecting rubber into the fixture, the double-layer pressure sealing drainer has the following advantages: time saving, force saving, low cost, better effect, wide application range, and suitability for the special-shaped pipe, the device or other straight pipe segments with a diameter phi larger than or equal with 57mm.
Description
Technical field
The utility model relates to the band means of press seals of special-shaped pipeline in oil refining, the chemical plant installations.
Background technique
In oil refining, chemical process, band presses the special-shaped pipeline (as: saddle interface, eccentric reducer, reducing tee, isometrical, reducing cross, E shape pipeline etc.) of (middle pressure, the non-inflammable and explosive medium of low pressure) to move continuously through long period on the main equipment, because burn into washes away and causes that special-shaped pipeline often leaks.In order to control the leakage of special-shaped pipeline, the existing leak stopping mode that adopts has two kinds:
1, " individual layer drainage technology "
Adopt " individual layer drainage technology ", medium generally all along tube wall to around wash away (as Fig. 1～2a), rather than become straight line to external leakage, the diameter of individual layer drainage device again must not be greater than the minimum diameter of former pipeline, can not dose sealing material again, so use the individual layer drainage device to carry out special-shaped pipeline when sealing once more, the butt weld of drainage device and former pipeline always has medium outwards to reveal, stoping the transition of Welding Molten Drop greatly to weld seam, it can not be welded, especially press special-shaped pipeline in, use " individual layer drainage technology " can't carry out welding operation especially.
2, " jig injecting glue pressure sealing "
Special pipe has saddle interface, eccentric reducer, reducing tee, isometrical, reducing cross, E shape pipeline, main equipment etc., thus bring very big difficulty for the manufacturing of jig, and the cost height, minimum more than 1500 yuan; Human input is bigger, and minimum 4 talents can complete operation; Operating time is long, needs at least more than 4 hours; Sealing effect is relatively poor.Owing to be that special pipe is sealed, when jig was installed, very difficult assurance was combined closely.Especially middle pressure pipe road more is difficult to reach the effect of sealing fully.
In view of the special pipe out-of-shape, using " individual layer drainage technology " can't be controlled, even manage to adopt " jig injecting glue pressure sealing " to control, also will drop into a lot of human and material resources and financial resources, and can not get optimum efficiency.
Summary of the invention
In order to overcome " individual layer drainage technology " and " leak stopping of jig injecting glue " use defective on band pressure special-shaped pipeline, improve the control efficiency of similar leak source, according to on-site actual situations, the utility model designs a kind of special-shaped pipeline bilayer zone means of press seals drainage device.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of special-shaped pipeline bilayer zone means of press seals drainage device is made up of special pipe and bilayer zone means of press seals drainage device.Special-shaped pipeline comprises pipeline 1, pipeline 2, and bilayer zone means of press seals drainage device comprises bile duct, sealing material, shell, flange.Press leak source during 2 of pipeline 1 and pipelines have, press around the leak source center line during bile duct is installed on, and be solidly connected with pipeline 1 and 2 of pipelines, sealing material is dosed in the periphery of bile duct, the periphery of sealing material is equipped with shell, shell one end and pipeline 1 and pipeline 2 welding, and the other end is connected with flange.
Above-mentioned sealing material is the mineral fibre packing.
The beneficial effect of advantage of the present utility model and generation is:
The utility model carries out selection, reconditioning manufacturing according to the shape of special pipe local irregularities, and volume is little, and sealing surface is littler, less than the sealing surface of " jig ", be easy to process and install.Cost is very low, and is the highest less than 1500 yuan; Human input is few, and 2 people just can finish the operation of small-sized leak source; Operating time is short, and small-sized leak source has 1 hour just can be finished; Big leak source also only needed just can finish in 4-6 hour.Good sealing effect, comparing courage layer, sealing layer with " individual layer drainage technology " can temporary sealing fully, makes one side welding with back formation obtain quality assurance.
The utility model adopts " double-deck drainage technology ", can reach permanent sealing fully through welding.Using effect at special-shaped pipeline is compared with existing " jig injecting glue pressure sealing ", save time, laborsaving, cost is low, effect is excellent, and is applied widely, can be used on diameter and equals 57mm special-shaped pipeline, equipment and other straight length greatly.

Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described again:
Shown in Fig. 2 b, a kind of special-shaped pipeline bilayer zone means of press seals drainage device is made up of special pipe (E shape pipe) and bilayer zone means of press seals drainage device.Special-shaped pipeline comprises pipeline 1, pipeline 2; Bilayer zone means of press seals drainage device comprises bile duct 4, sealing material 5, shell 6, flange 7.Pipeline 1 and pipeline 2 are respectively DN400 and DN100,, bile duct 4 is seamless steel pipe DN50, housing 6 is seamless steel pipe DN80; During having, 2 of pipeline 1 and pipelines press leak source 3, bile duct 4 is installed on around middle pressure leak source 3 center lines of 2 of pipeline 1 and pipelines, and be solidly connected with pipeline 1 and 2 of pipelines, sealing material 5 one mineral fibre packings have been dosed in the periphery of bile duct 4, the periphery of mineral fibre packing is equipped with shell 6, shell 6 one ends and pipeline 1 and pipeline 2 welding, the other end of shell 6 is connected with flange 7, and bile duct 4 and mineral fibre packing place shell 6.
Courage layer 4 play the limited flow rate effect, change the trend of medium, reduce the rate-of flow in the weld gap, for the mineral fibre packing provides a strong support.Sealing layer mainly is to be used for temporary sealing fully.Shell 6 is fixing mineral fibre packings, lays the first stone by being welded as final sealing fully.Flange 7 is used for installing blind plate or mounted valve.
