Description
Technical field
Connect the present invention relates to a kind of pipeline and cut equipment of relocating, the gas pipeline plugging holes system of especially a kind of on-line production
System.
Background technology
In fuel gas transmission field, how to ensure the safe and efficient operation of fuel gas transmission pipeline is the important work of such enterprise
Make content.During the management service of fuel gas transmission pipeline, it is often necessary to pipeline connect and cuts operation of relocating.Traditional pipe
Road, which connects, to be cut diversion project and mainly uses manual work mode, and it is that the gaseous-pressure in pipeline is reduced to comparatively safe scope
It is interior, then pipeline connect using instruments such as gas cutting, electric welding by operating personnel and cuts the operational method relocated.Traditional operating type
The operating pressure of pipeline is depressured firstly the need of by the combustion gas in diffuse channel, then pipeline carried out by cutting torch again
Perforate, gas shutoff is carried out using bladders brick wall, connected using pipe nipple, and operation of relocating is cut to complete to connect by band fire welding.It is this
Operating type is primarily present some following problem, on the one hand since it is desired that decompression can have an impact to the just conventional gas of user, leads to
Often need to carry out in the just conventional gas gap of night or user, have particular/special requirement to the activity duration, particularly in urgent speedily carry out rescue work not
It can guarantee that the just conventional gas needs of user；On the other hand need to diffuse substantial amounts of combustion gas in decompression, not only waste of resource, and
Environment can be affected, meanwhile, this operating type can produce naked light when being welded using cutting torch, fire, for combustion gas
Both make to be depressured for this combustible material and higher danger still be present, operative skill and business element to operating personnel
Matter requires higher.
Fuel gas transportation pipeline to solve the problems, such as traditional, which connects, to be cut operating type of relocating and exists, those skilled in the art's research
Develop the gas pipeline holing and sealing machine and method of a set of on-line production, mainly including four-way pipe fitting, sandwich valve, tapping machine,
The appurtenances such as plugging device, cutting serrated knife, expansion cylinder and bypass pipe, the flat pipe of string.In connecing and cutting operation process of relocating, four first
Way pipe fitting, diffusion valve are respectively welded at the both ends for needing repairing or changing pipeline, and sandwich valve is separately mounted to by flange
On corresponding four-way pipe fitting；Then tapping machine is separately mounted on corresponding sandwich valve by flange and connects the flat pipe of string, and
Drive the cutting serrated knife in tapping machine to cut pipeline by hydraulic station, unload tapping machine from sandwich valve after the completion of cutting
Under；Then plugging device is separately mounted on corresponding sandwich valve and connects the flat pipe of string and bypass pipe, then driven by hydraulic station
Expansion cylinder blocks to pipeline in dynamic tapping machine, combustion gas is passed sequentially through the pipeline of side, four-way pipe fitting, sandwich valve, closure
Plugging device, sandwich valve, four-way pipe fitting, the pipeline that device bypass pipe reaches opposite side realize connection, now can be to the pipeline of centre
It is repaired or replaced；Complete maintenance or one change after, by plugging device from sandwich valve removal, and by means for placing plug by block pacify
It is attached in four-way pipe fitting with blocking pipe cutting mouth, whole operation is completed finally by blind plate is installed in four-way pipe fitting
Process.The keying of pipe cutting mouth is realized by sandwich valve in above-mentioned operation process.The gas pipeline of this on-line production is opened
Hole plugging device is for traditional operating type, it is not necessary to pipeline is depressured, the just conventional gas of user will not be produced
Influence, activity duration and mode are more flexible, it is not necessary to the instrument of naked light is produced using cutting torch, fire weldering etc., security is higher；Together
When only need to diffuse a small amount of combustion gas in whole operation process, the energy can be saved, have preferable economic effect and society imitate
Fruit.
But existing holing and sealing machine still has more problems of storing up, master is showing following several respects：First, it is existing to open
The position that machine its hydraulic pressure pipe connector in hole is set is higher, and installation connection is not easy in operation process, have impact on operating efficiency, especially
It is the tapping machine for big specification, it is necessary to operating personnel carry out the connection of climbing just achievable hydraulic tube, enhances operation difficulty
And danger；2nd, existing sandwich valve mainly uses manual manipulation mode, needs operating personnel to pass through crank in operation process
The unlatching of wherein seal disc is repeated and closes valve, operating efficiency is relatively low and the labor intensity of operating personnel is larger；3rd, it is existing
Pipe cutting serrated knife is provided only with 4 groups of 16 cutters tooth, and in every group 4 cutters tooth edge width it is equal and along the normal side of perisporium
To setting from inside to outside, its single cycle amount of feeding is smaller, and rotary speed unstabilization is determined, and can produce larger cutting noise, mainly
Because the camber line between adjacent cutter tooth circumferentially is in larger distance, cause the continuity of cutting poor, simultaneously as 4 knives in every group
The edge width of tooth is set from inside to outside along the normal direction of perisporium, is easy to make cutter tooth two during pipe cutting
The discontinuity equalization of side, the rate of wear of cutting serrated knife is accelerated, have impact on service life, and enhance cost accordingly.
The content of the invention
It is an object of the invention to provide a kind of on-line production gas pipeline plugging holes system, and it has easy to operate, operation
