Description
Technical field
The utility model relates to a kind of seal arrangement, particularly relates to a kind of gas pipe line on-line rinsing seal arrangement, is applied in the online dynamically flushing process of blast furnace gas, coke-stove gas, coal gas of converter and other energy medium pipeline.
Background technique
Wuhan Iron and Steel Plant Fuel Gas Plant blast furnace, converter, coke-stove gas pipe network and facility spread all over Wuhan Iron and Steel Plant plant area.Because of in coal gas containing various impurity, dust stratification in gas pipe line facility, long-pending burnt and how stifled phenomenon is general, cause line clogging, flow resistance increase, considerable influence is produced to system process situation and equipment security of operation.In recent years, under not with the condition of coal gas high-pressure wash cleaning by high pressure water jet technology because having, cleaning gas facility is effective, sweeping efficiency is high and be used widely.For keeping gas pipe line facility normally run and use safely, under all needing the condition of on-line operation every year, carry out a large amount of high pressure water cleaning works.In cleaning process, clean pipe because of high pressure water and clean shower nozzle and need not stop mobile position in pipeline, gas in pipelines leaks unavoidable.Therefore, current high pressure water cleaning cleaning mode all adopts stops the supple of gas or steam after replacement Treatment coal gas to gas facility, opens manhole or clean-out hatch carries out corresponding cleaning process to local or whole piece pipeline.
Local pipeline section generally in gaspipe network and primary valve are difficult to the chance of stopping coal gas maintenance, the result of long-time running is that some part interior incrustation are serious, abnormal increase is damaged in the resistance of section of tubing inside, but need the pipeline section of cleaning can not close step-down cannot block up blind plate or use the restriction of the production of each main body factory and service arrangement not possess the condition of stopping cleaning coal gas by coal gas due to valve, just must clean this fault pipeline section online.Therefore, conventional high-pressure sewer flushing vehicle cleaning way can not be satisfied the demand.
For realizing not stopping coal gas, safety successfully carries out high pressure water cleaning to pipeline, effectively cuts off the water of coal gas, the seal arrangement of gas is the key that on-line rinsing designs.Because seal arrangement will realize gas in pipelines medium and outside reliably to cut off, the personal safety of operating personnel in online cleaning work process could be ensured.And in whole operation process, seal arrangement elongates or shortens, to adapt to the cleaning of different length pipeline according to actual dynamic adjustment pipeline.
Model utility content
The purpose of this utility model is to provide a kind of gas pipe line on-line rinsing seal arrangement, and sealing device can make gas pipe line and washing unit be tightly connected, and has ensured the personal safety of on-line cleaning operating personnel.
The utility model is achieved in that
A kind of gas pipe line on-line rinsing seal arrangement, it comprises auxiliary flushing pipe or valve body, high pressure water washing pipe and stuffing box; High pressure water washing pipe and auxiliary flushing pipe connect together by described stuffing box, or high pressure water washing pipe and valve body connect together by described stuffing box;
Described stuffing box comprises packing, Gland, the stuffing box support be placed in outside high pressure water washing pipe, described stuffing box supports and be provided with packing groove between high pressure water washing pipe, compress with Gland after packing being placed in packing groove, described Gland supports with stuffing box and is fixedly connected with;
The flange of described auxiliary flushing pipe or valve body and stuffing box support and are tightly connected;
Described stuffing box supports and be provided with seal ring between high pressure water washing pipe.
In the utility model, described high pressure water washing pipe can move axially, and realize elongating or shortening in gas pipe line, this structure goes for the cleaning of different gas pipe line.
The beneficial effects of the utility model are: 1, can not only realize cleaning gas pipe line online, solve the difficult problem that can not clean online; And different length, the gas pipe line of caliber and the cleaning of valve can be adapted to, applied widely.2, stuffing box supports, sealing between Gland and high pressure water washing pipe adopts O RunddichtringO to seal, realize the object that gas impurity is intercepted, adopt the completely sealing of packing, Gland realization to coal gas, blocking-up coal gas leaks, good sealing effect, can ensure the personal safety of online cleaning work personnel.3, high pressure water washing pipe needs protract mobile by operating personnel or retreat mobile according to cleaning when rinsing operation, with support stuffing box generation relative movement, can realize different length, the gas pipe line of caliber and the cleaning of valve.4, structure simple, be convenient to install.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the present utility model.
In figure: 1, stuffing box supports, 2, auxiliary flushing pipe, 3, flange, 4, Gland, 5, O RunddichtringO, 6, packing, 7, bolt, 8, bolt, 9, bolt, 10 bolts, 11, high pressure water washing pipe.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1, a kind of gas pipe line on-line rinsing seal arrangement, it comprises auxiliary flushing pipe 2, high pressure water washing pipe 11, and by stuffing box that auxiliary flushing pipe 1 and high pressure water washing pipe 11 connect together;
Described stuffing box comprises Gland 4, packing 6 and the stuffing box be placed in outside high pressure water washing pipe 11 supports 1, and described stuffing box supports between 1 and high pressure water washing pipe 11 and is provided with packing groove, is placed in packing groove by packing 6; Described Gland 4 entirety, in L-type, is supported 1 with stuffing box after packing 6 compresses by described Gland 4 and is fixedly connected with by bolt 9, bolt 10;
Flange 3 and the stuffing box of described auxiliary flushing pipe 2 are supported 1 and are fixedly connected with by bolt 7, bolt 8, and with washer sealing;
