Abstract
The utility model discloses a rubber bag for plugging large-caliber pipelines, particularly an inflatable rubber bag for sealing the pipelines, which is used for construction process of large-caliber petroleum pipelines, large-caliber gas pipelines and the like. The rubber bag comprises a bag body (1) and a bag nozzle (2); at least one layer of high-strength nylon framework cloth (3) is arranged in a barrel wall forming the bag body (1); the bag body (1) and the bag nozzle (2) adopt an integral structure; a multi-layer disc (5) is arranged on the bag nozzle (2); and the bag nozzle (2) is connected with the bag body (1) through the multi-layer disc (5). The rubber bag can bear larger pressure in the pipelines and has good sealing effect.
Description
Technical field
The invention belongs to the pipe fitting field, relate to a kind of large diameter pipeline work progresss such as oil, rock gas that are used for and be used for the aerated capsule of closed conduit.
Background technique
China Intellectual Property Office discloses the utility model patent (notification number be CN 2711504) of a kind of pipeline with air bag on July 20th, 2005.This air bag is used for to the construction of, drainage pipe, adopt by bottom, utricule, top and the valve cock that is installed in the top that the mould vulcanized rubber is Integratively formed to be inflatable utricule, valve inside and tightening nut have been connected on the valve cock, utricule outer wall circumference is provided with several burr, and its utricule is up and down the slightly round long tubular of the conical surface.
The utricule of above-mentioned air bag is mainly rubber structure, is suitable for to, the less pipeline of draining equal pressure, if when being used for the bigger pipeline of oil, rock gas equal pressure, the utricule of rubber bears pressure difference, promptly can break, and does not have the effect of sealing.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of large diameter pipeline sealing capsule, and this capsule can bear pressure bigger in the pipeline, good sealing effect.
For overcoming the above problems, concrete technological scheme of the present invention is as follows: a kind of large diameter pipeline shutoff capsule, form by utricule and Nang Zui, and at least one floor height intensity polyamide skeleton cloth is arranged, utricule and Nang Zui are structure as a whole.
Nang Zui is provided with the multilayer disk, and Nang Zui links together by disk and utricule.
Constituting in the bucket wall of utricule has at least one floor height intensity polyamide skeleton cloth, makes when this capsule is used for bigbore pipeline such as the bigger oil of pressure, rock gas, and good seal performance, compression resistance are strong; The outer circumference portion that Nang Zui contacts with utricule is arranged with the multilayer disk, makes the area of contact of the rubber of sulfuration and Nang Zui bigger, and Nang Zui combines more firm with utricule.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is the structural representation of large diameter pipeline shutoff capsule.
Embodiment
A kind of large diameter pipeline shutoff capsule, form by utricule 1 and capsule mouth 2, in the bucket wall of formation utricule 1 at least one floor height intensity polyamide skeleton cloth 3 is arranged, utricule 1 is barrel-like structure with capsule mouth 2 by mould disposable integral sulfidization molding, and this barrel-like structure can be for having the barrel-like structure of sphere or ellipsoid end socket.
Capsule mouth 2 is provided with multilayer disk 5, and capsule mouth 2 links together by disk 5 and utricule 1.The longitudinal section of this disk 5 is rectangle, the big shape of surface of contact such as trapezoidal, dish-like, all falls into the scope of this claim protection.
Embodiment:
As shown in Figure 1, large diameter pipeline shutoff capsule is made up of utricule 1 and capsule mouth 2, in the bucket wall of formation utricule 1 two-layer high-strength nylon skeleton cloth 3 is arranged, between the two-layer high-strength nylon skeleton cloth 3 is rubber layer 4, and utricule 1 is barrel-like structure with capsule mouth 2 by mould disposable integral sulfidization molding.
Claims (2)
1. a large diameter pipeline shutoff capsule is made up of utricule (1) and Nang Zui (2), it is characterized in that: in the bucket wall of formation utricule (1) at least one floor height intensity polyamide skeleton cloth (3) is arranged, utricule (1) is structure as a whole with Nang Zui (2).
2. capsule as claimed in claim 1 is characterized in that: Nang Zui (2) is provided with multilayer disk (5), and Nang Zui (2) links together by disk (5) and utricule (1).
