Abstract

The utility model discloses a multi-layered wrapped pressure vessel. The multi-layered wrapped pressure vessel comprises end enclosures and a barrel, the barrel comprises an internal barrel and multiple layers of wrapping layer plates, each layer plate is provided with drain holes, the drain holes of the outmost layer of layer plate are connected with a drain duct, and the drain duct is connected with the drain holes through drain hole-connecting flanges. The whole multi-layered wrapped pressure vessel can receive thorough anticorrosive treatment, can be used under water, damp and corrosive environments after anticorrosive treatment, and is also suitable for use in the underground environment.

Description

A kind of multilayer binding pressurized container

Technical field

The utility model relates to a kind of pressurized container, especially a kind of pressurized container with multilayer binding structure.

Background technique

Pressurized container is the necessary key equipments of industry such as chemical industry, oil refining, light industry and the energy, is divided into two kinds of structure types of individual layer and multilayer usually.The cylindrical shell of multilayer binding pressurized container is made up of inner core and laminate, and cylindrical shell is to be formed by the plate of moderate thickness gang welding that quality is superior to slab, and the thickness of cylindrical shell does not receive the restriction of heavy plate rolling ability; And the weld seam that constitutes each laminate of cylindrical shell staggers mutually; Do not have A, the category-B weld seam that connects along wall thickness on the cylindrical shell, therefore, the multilayer binding pressurized container is compared with the individual layer pressurized container; Not only solved the problem that heavy wall is made; And have special advantage at aspects such as the reasonable utilization of material, Securities, thereby the multilayer binding pressurized container has been widely used in the industrial every field as a kind of structural type of pressurized container.The multilayer binding pressurized container is in manufacture process; Whenever all escape orifice will be set on the plate layer by layer, in case the escape orifice effect is that inner core receives corrosion and defective occurs and run through, pressure medium can flow out from escape orifice; Play the safety alarm effect, reach the failure mode of leakage prior to explosion.In addition, in the wrapping welding process, escape orifice can make the gas between laminate discharge, and avoids gases affect welding quality residual between laminate.

In order to prevent that source of corrosion from directly getting between laminate and inner tank theca through wrapping up the laminate escape orifice; Inner core or laminate are caused corrosion; Multilayer binding pressurized container in use escape orifice need keep unimpeded, therefore, water, humidity are arranged, under the environment that is corrosive; Be not suitable for the use of multilayer binding pressurized container, limited the use that multilayer bag pressure is pricked container.

The model utility content

The technical problem that model utility will solve: a kind of multilayer binding pressurized container is provided; This multilayer binding pressurized container can carry out thoroughly preservative treatment of integral body; Can water, humidity arranged, use under the environment that is corrosive through the multilayer binding pressurized container after the preservative treatment, and be applicable in the buried environment and use.

The technological scheme that the technical solution problem is taked: a kind of multilayer binding pressurized container, comprise end socket and cylindrical shell, said cylindrical shell is made up of inner core and multilayer binding laminate, on each laminate, is provided with escape orifice, on the escape orifice of outermost surface laminate, connects the conduit of releasing.

Improvement as the utility model: on the escape orifice of outermost surface laminate, be welded with escape orifice and connect edge, the conduit of releasing meets edge and escape orifice UNICOM through escape orifice.

Beneficial effect: the multilayer binding pressurized container of the utility model; Owing to adopted said multilayer binding pressurized container, comprise end socket and cylindrical shell, said cylindrical shell is made up of inner core and multilayer binding laminate; On each laminate, be provided with escape orifice; On the escape orifice of outermost surface laminate, connect the technological scheme of the conduit of releasing, escape orifice is drawn, make the multilayer binding pressurized container of the utility model to carry out thoroughly preservative treatment of integral body to outer wall easily through the conduit of releasing; Preservative treatment can not stopped up escape orifice; Can water, humidity arranged, use under the environment that is corrosive through the multilayer binding pressurized container after the preservative treatment, and be applicable in the buried environment and use, expand the using scope of multilayer binding pressurized container; Owing to adopted and on escape orifice, be welded with escape orifice and connect edge; The conduit of releasing connects the technical characteristics of edge and escape orifice UNICOM through escape orifice; Can the multilayer binding pressurized container be transported to the mounting point, connect the conduit of releasing again after fixing; Make things convenient for the transportation and the installation of multilayer binding pressurized container, and can be easily a plurality of escape orifices on the same multilayer binding pressurized container have been connect after the edge UNICOM again via logical drawing of the conduit of releasing, saved materials consumption.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.

Fig. 1 is the multilayer binding construction of pressure vessel schematic representation of the utility model.

Embodiment

As shown in Figure 1; The multilayer binding pressurized container of the utility model comprises end socket and cylindrical shell, and said cylindrical shell is made up of inner core 5 and multilayer binding laminate 4; On each laminate, be provided with escape orifice 3; On the escape orifice of outermost surface laminate, connect the conduit 1 of releasing, on the escape orifice of outermost surface laminate, be welded with escape orifice as improvement and connect edge 2, the conduit of releasing meets edge and escape orifice UNICOM through escape orifice.

Claims

1. a multilayer binding pressurized container comprises end socket and cylindrical shell, and said cylindrical shell is made up of inner core and multilayer binding laminate, on each laminate, is provided with escape orifice, it is characterized in that: on the escape orifice of outermost surface laminate, connect the conduit of releasing.

2. multilayer binding pressurized container according to claim 1 is characterized in that: on the escape orifice of outermost surface laminate, be welded with escape orifice and connect edge, the conduit of releasing meets edge and escape orifice UNICOM through escape orifice.
