Abstract
The utility model belongs to the technical field of pipeline sealing, in particular to a T-shaped sealing ring used for sealing pipes when polythene and polyvinyl chloride pipes are connected through a rapid joint. The T-shaped sealing ring is integrated by an axial sealing sleeve and an annular sealing tongue, wherein the annular sealing tongue is located in the axial sealing sleeve and forms a T-shaped sealing ring, thereby the sealing tongue of the utility model plays the sealing function to the end surface on the connection of the pipes, and simultaneously the axial sealing sleeve further plays the axial sealing function to the connection of the pipes. Therefore, the sealing ring has ideal dual-directional sealing effects, can fully satisfy the sealing of the pipes which are scratched, knocked and repeatedly used, guarantees good sealing property and safety property of pipeline engineering, saves an amount of cost for using units, and is suitable for large-scale transmitting engineering, such as oil chemical industry, mash gas, gas transmissions and the like.
Description
One, technical field
The utility model belongs to the seal for pipe joints technical field, what be specifically related to is a kind of T shape seal ring that polyethylene, polychloroethylene pipes are used for the tubing sealing when connecting by rapid pipe joint, is specially adapted to the sealing for tubing joints of large-scale transmission engineerings such as coal mine gas, combustion gas conveying, petrochemical industry.
Two, background technique
At present, large-scale transmission engineerings such as petrochemical industry, coal mine gas, combustion gas conveying generally use polyethylene, polychloroethylene pipes to finish the pipeline connection by rapid pipe joint (as zl200720010154.4), cooperate this kind pipeline Placement generally all to be to use existing ring-shaped rubber seal ring sealing, reveal to avoid ducted medium.But find that in actual applications general ring-shaped rubber seal ring when being used for the tubing connection sealing of big caliber, being difficult to centering, aligning in installation process at present, has increased mounting hardness, also influences sealing effect.In addition, owing to polyethylene, polychloroethylene pipes are easy to produce cut in transportation process, use existing O-ring seal meeting to influence sealing effect.And the sealing effect of reusable polyethylene, polychloroethylene pipes (produce cut when maintenance, dismounting, collide with) is not satisfied in O-ring seal at all, cause the reusability of its tubing poor (colliery highly gassy mine tubing repeat usage height), caused very big waste.
Three, summary of the invention
The purpose of this utility model provides a kind of T shape seal ring that cooperates polyethylene, polychloroethylene pipes to use, be particularly useful for the connection sealing of bassoon diameter pipes, good sealing effect, easy centering, centering during installation, not only improve working efficiency, also can guarantee the sealing effect of the tubing of cut and recycling simultaneously.
The purpose of this utility model is achieved in that T shape seal ring is to constitute integrative-structure by axial seal cover and ring packing tongue, and the ring packing tongue is positioned at the axial seal cover, its formation T shape sealing surface.The middle pit of the stomach on the ring packing tongue and polyethylene, polychloroethylene pipes internal diameter are complementary, and the internal diameter of axial seal cover and the external diameter of tubing are complementary.During use, the utility model is installed in the polyethylene that needs butt joint, the joint of polychloroethylene pipes, and reinforces, install very convenient with pipe clamp.The utility model adopts T shape sealing surface structure, under the effect of pipe clamp, not only its ring packing tongue has played seal action to the end face of tubing joint, and its axial seal cover has also played the effect of axial seal to the tubing joint simultaneously, so has obtained very desirable two way sealed effect.The sealing of the tubing that two way sealed form of the present utility model can satisfy cut fully, collide with, reuse, thus pipework excellent sealing performance and Safety performance guaranteed, for applying unit has been saved a large amount of costs.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
User mode figure of the present utility model when Fig. 2 connects for pipeline;
Fig. 3 to Fig. 5 adopts the structural representation of multi-form sealing surface for sealed tongue of the present utility model.
Five, embodiment
As shown in Figure 1, the utility model adopts rubber material to be pressed into integrative-structure by axial seal cover 1 and ring packing tongue 2, and ring packing tongue 2 is positioned at axial seal cover 1, has formed the seal ring of T-shaped section.The middle pit of the stomach d1 of the ring packing tongue 2 of sealing circle should be complementary with the internal diameter of polyethylene, polychloroethylene pipes, the inner diameter d 2 of axial seal cover should be complementary with the external diameter of tubing 4 joints, like this, when tubing connects, the utility model seal ring is installed in the tube connector place (see figure 2) of butt joint, and reinforces with pipe clamp 5 chuckings.The outside of the axial seal cover 1 of sealing circle also can be provided with outside projection circle 3; The sealing surface of its ring packing tongue 2 can be designed to the plane, also can be the rectangular waveform (see figure 3), zigzag fashion (see figure 4) or corrugated (see figure 5), tubing is in the process that connects like this, because the effect (the contract face effect of tube connector place and pipe clamp 5) of pipe clamp 5, make the axial seal cover 1 and the ring packing tongue 2 of the utility model seal ring be subjected to radial and axial pressure distortion respectively, played the effect of two way sealed, thereby reached better sealing effect, the utility model can be widely used in petrochemical industry, coal mine gas, large-scale transmission engineerings such as combustion gas conveying.
