Abstract
The utility model discloses a loop type flange short section, which is used for connecting gas and liquid conveying pipelines and saves time and labor. The loop type flange short section comprises a pipeline short section, wherein a fixed flange disk is mounted at one end of the pipeline short section; a moveable flange disk is mounted at the other end of the pipeline short section; and a sealing ring is mounted between the pipeline short section and the moveable flange disk. The sealing ring can prevent the moveable flange disk from falling off from the pipeline short section and can prevent leakage of materials in the pipeline. When the loop type flange short section is applied to pipeline connection, fire and electric welding are avoided during connection, so the potential safety hazard is eliminated, the construction safety is guaranteed and the construction efficiency is improved.
Description
Technical field
The utility model relates to the connected element of gas, liquid transfer line, a kind of loose flange type pipe nipple particularly, and it is movable and fixed that the flange plate at these flange spool two ends is respectively.
Background technique
Flange spool is the accessory of gas, liquid conveyance conduit or pipeline, be exactly one section two ends with pipeline or the pipeline of flange plate, in service in actual production, the connection of pipeline or pipeline often can be used flange spool.The flange spool that uses at present, an end is fixed flange plate, because the connecting bolt hole of the connecting bolt hole on the flange plate and pipeline upper flange plate aligns the reason of inconvenience, the other end is not established flange plate, the flange plate of the other end will weld in the connection construction scene.During the mounting flange pipe nipple, first the fixed flange on the flange spool is fixed on the flange plate of connecting line, the flange plate of the flange spool the other end is fixed on first on the corresponding pipeline flange plate, again by electric welding with the welding of the flange plate on flange spool and the corresponding pipeline, reach the purpose that pipeline connects.The pipeline of production run generally all can be connected on the pressurized container, and when carrying out the pipeline pipeline purging, differs and thoroughly remove surely the interior internal memory material of pipeline, when flange spool connects the electric welding construction, causes easily security incident.
Summary of the invention
The utility model provides a kind of loose flange type pipe nipple in order to overcome above-mentioned technical problem, avoids electric welding field, utilizes moving flange plate to dock with the pipeline flange plate, makes things convenient for the installation of connecting bolt, guarantees construction safety.
The utility model is achieved in that a kind of loose flange type pipe nipple comprises the pipeline pipe nipple, and an end of pipeline pipe nipple is fixed flange, and the other end of pipeline pipe nipple is installed moving flange plate, between pipeline pipe nipple and moving flange plate seal ring is housed.Seal ring can prevent that moving flange plate from coming off from the pipeline pipe nipple, also can avoid the seepage of material in the pipeline.
The beneficial effects of the utility model are:
1, the utility model arranges respectively fixed flange and moving flange plate by the two ends at the pipeline pipe nipple, effectively utilize flange spool and realize the connection of pipeline, and when flange spool connects, need not get angry, need not electric welding, eliminate potential safety hazard, guarantee construction safety.
2, by between moving flange plate and pipeline pipe nipple, seal ring being set, avoided coming off and seepage after pipeline is connected of moving flange plate.
3, utilize the utility model to carry out pipeline and connect, time saving and energy saving, improved efficiency of construction, have obvious economic benefit and social benefit.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.As shown in drawings, a kind of loose flange type pipe nipple comprises pipeline pipe nipple 1, and an end of pipeline pipe nipple 1 is fixed flange 2, and the other end of pipeline pipe nipple 1 is installed moving flange plate 3, between pipeline pipe nipple 1 and moving flange plate 3 seal ring 4 is housed.Moving flange plate 3 is the cirque body that are provided with connecting bolt hole 5, and its inner circle cooperates with the cylindrical of pipeline pipe nipple 1.
In the process of using, at first fixed flange 2 is connected with flange plate on the pipeline, and locks by connecting bolt hole 5; Then by rotating moving flange plate 3, the connecting bolt hole 5 on the moving flange plate 3 is aimed at the flange plate connecting bolt hole on the pipeline to be connected; At last, moving flange plate 3 lockings are got final product.In the installation process of this flange pipe nipple, need not fire operation, the hidden danger of having avoided fire operation to bring; And whole installation process, high working efficiency not only, and also time saving and energy saving; And can effectively prevent the seepage of connecting line.
Claims (2)
