Abstract
The utility model discloses an ultralong rubber lining pipeline which comprises a steel pipe and flanges, wherein a rubber plate is arranged in the steel pipe; a tractor traction head is arranged in the rubber plate and is connected with a rubber stopper through a bolt. According to the ultralong rubber lining pipeline provided by the utility model, the number of leakage points is reduced, the environment pollution is alleviated, and the use cost is reduced. The ultralong rubber lining pipeline provided by the utility model is used for conveying liquid materials such as acid, alkaline and salt.
Description
Technical field
The utility model relates to the liquid material pipelines such as transport acid, alkali, salt, relates in particular to a kind of super long type rubber lining pipeline.
Background technology
Requirement and the regulation of the industry standard HG21501-93 " rubber lined steel pipe and pipe fitting " that the standard that current domestic rubber lined pipe production is followed is the distribution of former Ministry of Chemical Industry and the related Sections of HG/T20677-1990 " rubber lining chemical industry equipment " the 4.3rd, the processing technology of taking has two kinds basically, a kind of for ironing and press or roll by hand, with flatiron or pressure roller manual by the offset plate compacting in steel pipe, another kind is the air sac pressing method, be about to the air bag of inflation with passing through in pipe, make offset plate and steel pipe bonding, but the latter is because pressure is inadequate, easily cause the layering between offset plate and steel pipe, application seldom, although the former guarantees to some extent quality, but the restriction due to the staff brachium, the single-piece length of pipeline is all shorter, the pipeline that the bore of take is DN100 is example, can only accomplish the length of 2500mm, like this for the user, in the pipeline of equal length, flange, the large usage quantity of gasket seal and securing member, and leakage point is also a lot, use cost is higher.
Practical content
The purpose of this utility model is to provide and a kind ofly can reduces leakage point, and environmental contamination reduction reduces the super long type rubber lining pipeline of use cost.
The utility model is achieved in that a kind of super long type rubber lining pipeline, comprises steel pipe, flange, it is characterized in that: be provided with rubber slab in steel pipe, be provided with the hauling machine drawing head in rubber slab, the hauling machine drawing head has been bolted rubber bolt.
Rubber bolt described in the utility model is taper, and the major part place is more bigger than internal diameter of the pipeline, and the microcephaly place is less than internal diameter of the pipeline.
The material that rubber bolt described in the utility model adopts is to have flexible flexible material.
The utility model has reduced leakage point, has reduced environmental pollution, has reduced use cost.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
In figure: 1, rubber bolt; 2, bolt; 3, steel pipe; 4, flange; 5, rubber slab; 6, hauling machine drawing head.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing, a kind of super long type rubber lining pipeline, comprise steel pipe 3, flange 4, it is characterized in that: be provided with in steel pipe 3 in rubber slab 5, rubber slab 5 and be provided with hauling machine drawing head 6, hauling machine drawing head 6 is connected with rubber bolt 1 by bolt 2.Described rubber bolt 1 is taper, and the major part place is more bigger than internal diameter of the pipeline, and the microcephaly place is less than internal diameter of the pipeline; The material that described rubber bolt 1 adopts is to have flexible flexible material.During concrete enforcement, the utility model is used a kind of external diameter have flexible flexible material more bigger than internal diameter of the pipeline to make a conical objects, utilize tractive force to make it pass through rubber tube inner wall, the reaction force that utilizes its extruding to produce by the rubber slab compacting in steel pipe, realize bonding reliably, make rubber lined pipe length reach maximization.Concrete steps are as follows: first with cloth, wrap sebific duct, carefully sebific duct drawn in pipeline, after the sebific duct after confirming to draw in good condition, cloth is pulled out, squeeze into air sebific duct is heaved, and local and bonding by the bushing pipe road.Then at the inner lubricant that is coated with of sebific duct, use rubber bolt by the sebific duct compacting successively be lining into, should note can not staying bubble under offset plate in work progress simultaneously, again flange face has been handled well just after the offset plate compacting in guaranteeing pipeline.Because the utility model has been improved Lining Technology
,the length of single-piece rubber lined pipe can be done longlyer compared with similar products, has surmounted the relevant regulations in the national sector standard far away.Take nominal diameter DN100 equally as example, and maximum length can reach 6000mm, working pressure :-0.098MPa ~ 4.0MPa; The corrosion of the multiple strong acid and strong base of ability, as sulfuric acid, hydrochloric acid, alkali lye etc., in the chemical acid alkali medium, maximum operation (service) temperature can reach 120 ℃; Under normal service condition, design service life can reach 20 years.The utility model has not only reduced use cost and has also reduced leakage point, has reduced environmental pollution, the positive impact that the security civilization production management of enterprise is brought.
