Abstract
The utility model relates to a device for clogging construction pipelines in the process of the change of pipe segments. The utility model is composed of an expansion hand wheel (1), a tightening bolt (2), a draw rod (3), a feed hand wheel (4), a sleeve-shaped nut (5), a leading screw (6), a machine body (7), a seal guiding assembly (8), an optical shaft (9), a connecting box (10), a barrel type blockage (13), a pressure testing valve assembly (18), and a bracket guard rail (9). With the use the utility model, the uninterrupted pressure clogging operation can be carried out in pipelines made of various pipe materials for conveying medium, and the pipelines have a large pressure conveying range (0 to 6.4MPa); moreover, the blockage has the advantages that the construction process is simple, the openings and the consumed materials are few, the construction cost is low, etc.
Description
The utility model relates to and a kind ofly is used for industrial pipeline workflow reengineerings such as oil, chemical industry, plumbing, changes the equipment that the pipeline section process is carried out the shutoff operation to the construction pipeline.
Various industrial pipelines such as the oil of industrial and mining enterprise, gas, water, vapour often need carry out the pipe plugging operation because of reasons such as corrosion and damage, equipment reorganization and expansion, workflow reengineering or processing accidents.At present, though the various pipe plugging machineries and the technology that adopt can be finished stopping transportation pressure perforate shutoff operation, all exist certain not enough drawn game sex-limited both at home and abroad.For example, the disc type shutoff that the U.S. adopts is applicable to the discharge pressure that 2MPa is above, the sealing leakproofness reduces during hypotony, the bag-type blockage that Canada adopts then can only bear the following pressure of 0.4MPa, discharge pressure can not be too high, and the shortcoming of the liquefied ammonia freeze plugging that Ukraine adopts is to bring adverse effect to tubing.In addition, existing pipe plugging construction exist all that perforate quantity is many, shortcomings such as consumption pipe fitting, valve, obstruction are many, complex process, construction cost height.
Task of the present utility model is to provide a kind of pipeline stopping transportation pressure cartridge type blocking machine, this blocking machine can adapt to various discharge pressures, be applicable to various tubing and fed sheet of a media, utilize it can simplify pipe plugging greatly, construction process, reduce workload and materials consumption, reduce construction cost, overcome the shortcoming and defect of prior art.
The utility model be achieved in that it by hypertonic handwheel (1), turnbuckle (2), pull bar (3), feeding handwheel (4), shell-like nut (5), leading screw (6), body (7), sealing guidance set (8), optical axis (9), connect case (10), cartridge type plugging device (13), pressure testing valve group (18) and support guardrail (19) and form.Its structure and assembling feature are as follows: shell-like nut (5) is equipped with in body (7) upper end, shell-like nut (5) is gone up by the key connection feeding handwheel (4) is housed, sealing guidance set (8) is equipped with in the body lower end, and with connect case (10) and link to each other, body one side device has support guardrail (19), connects case one side and is provided with pressure testing valve group (18); Leading screw (6) is housed in the body (7), and leading screw (6) lower end links to each other with optical axis (9) by flange, and both match with shell-like nut (5) and sealing guidance set (8) respectively, and optical axis (9) lower end links to each other with cartridge type plugging device (13) by flange; Pull bar (3) is applied in leading screw (6) and the optical axis (9), and turnbuckle (2) and hypertonic handwheel (1) are equipped with in its upper end, and the lower end links to each other with cartridge type plugging device (13) by internal thread.This blocking machine is realized the shutoff operation in the following manner: after perforator is finished the perforate operation and removed from the construction pipeline, the sandwich valve (11) that 2 blocking machines is installed in special four-way threeway (12) top, shutoff construction pipeline section two ends is respectively gone up (four-way threeway and sandwich valve are welded on pipeline) before carrying out the perforate operation, and bypass line is linked to each other with the bypass mouth of pipe that 2 blocking machines connect on the case (10) respectively; Open sandwich valve conducting bypass flow process; The handwheel (4) that is rotatably installed in the blocking machine of pipeline upstream shutoff mouth makes leading screw (6) push optical axis (9) and cartridge type plugging device (13) decline; After treating that plugging device (13) is placed into the shutoff position, unclamp and remove turnbuckle (2), rotate handwheel (1) and go up the quadratic crank mechanism action that lifting rod (3) makes cartridge type plugging device (13), strut the shutoff tube, the rubber sealant that is attached on the shutoff drum outer wall is being pressed on the pipe plugging face, thereby realize the sealing of pipeline upstream cutting mouth.Be installed in another blocking machine blocking pipe downstream shutoff mouth of pipe downstream shutoff mouth according to the said process operation.After the improvement project construction of whole shutoff pipeline section finishes, by 2 blocking machines being removed from pipeline with aforementioned opposite program.
The utility model modern design, simple in structure, applied widely, utilize it can in the pipeline of various tubing and fed sheet of a media, big discharge pressure scope (0-6.4MPa), realize stopping transportation pressure shutoff operation.This blocking machine has also that construction process is easy, perforate quantity and consume few, the low cost and other advantages of material, and using effect and economic benefit obviously are better than prior art, are suitable for and apply.
Fig. 1 is a general structure schematic representation of the present utility model.
Fig. 2 is the utility model shutoff construction schematic representation.Among the figure, label 11 is a sandwich valve, and 12 is the four-way threeway, and 14 is bypass line, and 15 is bellows, and 16 is equilibrated valve, and 17 are the excision pipeline section, and 20 is pressure-equalizing pipe.
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
In the utility model, optical axis (9) is a hollow shaft, and its upper and lower end has respectively to connect uses flange; Connect case (10) and be cylindric, end face central authorities have through hole, and the side has for connecting the circular hole that bypass line and pressure testing valve group pipeline are used, and the bottom surface is uncovered; Cartridge type plugging device (13) is the cylinder of side longitudinal opening one by one, its end face central authorities are provided with the flange that is connected with end flange under the optical axis (9), be provided with center-pole in the cylindrical shell, center-pole upper end band external screw thread is so that link to each other with pull bar (3) lower end, bar is provided with two groups of (4 pairs every group) connecting rods up and down, each connecting rod the other end is fixed on the barrel by " U " shape seat, constitutes quadratic crank mechanism, and cylinder body outer wall is pasted with one deck rubber sealant.
