The utility model has the advantages that the requirement for the condition of a pipeline to be repaired is low, the adaptability is strong, the plugging performance is good, the durability is high, the damage is not easy, a bypass does not need to be additionally arranged on the pipeline, the man hour can be shortend, and the materials can be saved. The utility model is used for repairing and plugging operation without stopping transfer for delivery pipelines of gas, natural gas, oilfield, tap water, chemical liquid raw materials, etc.

Description

Pipeline online plugging device
The utility model relates to a kind of blocking device of pipeline maintenance usefulness, particularly a kind of pipeline online plugging device.
In the past, when pipeline breaks down, just the conveying that will stop the pipeline medium is keeped in repair, this mode, influence is seriously produced and life, in the last few years, for avoiding this drawback, developed and a kind ofly can in pipeline maintenance, not stop maintenance tool that pipeline carrying i.e. not stopping transportation perforate and blocking device, its blocking device mainly by leather cup formula plugging device, connect case, sandwich valve, base and constitute, it has realized the not maintenance of stopping transportation of pipeline.Along with its use, the place of some shortcomings has also appearred.1, its adaptability is relatively poor, and it only can execute reality (be not distortion of tube wall, tube wall does not have attachment) under the good situation of pipe condition, otherwise its shutoff sealing greatly reduces.2, the shutoff leather cup is more fragile in operation, and making it can not shutoff.3, on pipeline, be required to be its construction and set up an inicdental bypath in addition.
It is strong, durable and do not need to set up in addition the pipeline online plugging device of inicdental bypath outside this device that the purpose of this utility model is to propose a kind of adaptability.
Can realize the purpose of this utility model by following technical proposals, a kind of pipeline online plugging device, it comprises even case, sandwich valve, base, it is characterized in that the sidewall that connects case is provided with a by-pass port, base is a split type four-way pipe fitting about in the of, the internal diameter of this four-way pipe fitting and the external diameter of pipeline are equal to, plugging device top is for advancing transmission part, it connects main shaft and transmission shaft, main shaft is hollow, and transmission shaft is provided with in it, and the main shaft lower end has a nut, connect with last expansion wedge upper end spiral, the transmission shaft lower end is that interior side is enclosed within side's section of center bolt, and last expansion wedge is spun on respectively on the center bolt with following expansion wedge, and the screw thread of center bolt top and bottom is reverse, the elastic expansion jacket casing that effect by the expansion wedge can enlarge or dwindle is last, on the following expansion wedge, the outer surface of this expansion cylinder is one deck rubber.
The elastic expansion tube by inc elastic cylinder be fixed on this cylinder inboard wall and constitute to the panel of inner axes radiation more than two, panel and the surface of contact of upper and lower expansion wedge are that the outer inclined-plane of oblique and upper and lower expansion wedge coincide and leans on mutually, panel two ends up and down respectively is provided with the back plate, on the interior inclined-plane of the front end of back plate near upper and lower expansion wedge.
Technique scheme makes and the utlity model has following technique effect: 1, adaptability is strong, to the tube wall thickness differ, tube wall deformation and the appendiculate situation of tube wall all be suitable for, and has good shutoff sealing.2, the shutoff expansion cylinder is the elastic metallic cylindrical shell, and outer wall posts one deck rubber, and is durable in use, moreover the expansion cylinder of plugging device is upper and lower running, need not change curvedly, the clashing and breaking phenomenon can not take place.3, do not need to be provided with separately in addition bypass, connect a pipeline at this device even by-pass port of case and promptly form bypass, thereby shorten the man-hour of constructing, save material, efficiency of construction is improved.
Below in conjunction with accompanying drawing the utility model is further set forth:
Accompanying drawing 1 is schematic representation of the present utility model (broken section);
Accompanying drawing 2 is the enlarged diagram (in the frame of broken lines) of block head 4 in the accompanying drawing 1;
Accompanying drawing 3 is the plan view of block head 4 in the accompanying drawing 2.
With reference to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3: plugging device is by advancing transmission part 1, main shaft 2, transmission shaft 3, block head 4 to form.Advance transmission part 1 to can be manual, electronic or the hydraulic pressure form, its function is that main shaft 2, transmission shaft 3 upper and lower liftings and transmission shaft 3 are horizontally rotated.Plugging device is fixed on company's case 5 by the flange of lower end equipment.The sidewall that connects case 5 is provided with by-pass port 6, connects case 5 lower ends and is fixed on the sandwich valve 7, and sandwich valve 7 is fixed on the upper and lower split type four-way pipe fitting 8 of base.The external diameter of the internal diameter of four-way pipe fitting 8 and pipeline 9 is equal to, and it is fixed by welding on the outer wall of pipeline 9.Advance transmission part 1 to connect with the upper end portion of main shaft 2, transmission shaft 3.Main shaft 2 is a hollow-core construction, and transmission shaft 3 is located in it.Main shaft 2 underparts have nut and connect with last expansion wedge 10 spirals, are located by locating stud.Transmission shaft 3 lower ends are interior side's cover, and it is enclosed within side's section of center bolt 11.Last expansion wedge 10 and following expansion wedge 12 are spun on the upper and lower part of center bolt 11 respectively.The screw thread of center bolt 11 upper and lower parts is reverse.Expansion cylinder by the not closed cylindrical shell of elasticity 13 be fixed on cylindrical shell 13 inwalls and constitute to the panel 14 of inner axes radiation and the rubber layer 15 that is attached to cylindrical shell 13 outer wall more than two.Expansion cylinder is enclosed within on the upper and lower expansion wedge 10,12.Panel 14 is oblique with the surface of contact of upper and lower expansion wedge 10,12, coincide with the outer inclined-plane of upper and lower expansion wedge 10,12 and leans on mutually.After the upper/lower terminal of panel 14 respectively is provided with, pull 16, after pull 16 front end and lean against on the interior inclined-plane of upper and lower expansion wedge 10,12.When transmission shaft 3 drove center bolt 11 up times or rotates counterclockwise, upper and lower expansion wedge 10,12 relatively or reverse motions enlarged cylindrical shell 13 or dwindles by the effect with panel 14, after pull 16 and work to dwindle cylindrical shell 13.Block 17 is fixed on the expansion wedge, blocks panel 14 and does not allow its rotation.
The running of this device is: to the pipeline of need maintenance, first usefulness not stopping transportation boring device is respectively left a hole that is same as outer diameter tube at the two ends that it keeped in repair, then, load onto blocking device, and even connect bypass duct between the case at two, its block head drops to the shutoff position, the not closed place (or opening) of expansion cylinder cylindrical shell is towards the pipeline medium throughput direction, rotating drive shaft makes the relative movement of expansion wedge then, thus make the expansion cylinder distending and with the plugging hole driving fit.
This device is widely used in the not stopping transportation maintenance shutoff operation of delivery line of coal gas, rock gas, tap water, chemical industry liquid material etc.
