Abstract
The utility model relates to a pipe connecting and sealing device, comprising seal tapes inside two semicircular pipe threads whose both sides are provided with the connecting device that connects two pipe threads. The utility model is characterized in that a convex rib is arranged inside the pipe threads. The utility model has the advantages that the utility model not only prevents shift between pipes, but also can make seal better between pipes and pipe threads. The utility model has the advantage of swift and reliable connection which can be proceeded without good execution condition or under the atrocious weather condition.
Description
Technical field
The utility model relates to a kind of connection seal arrangement of pipeline.
Background technique
The interconnection technique of pipeline mainly contains following several at present: 1, metal solder is applicable to that the metal material pipeline connects; 2, electric heating fusion welding is applicable to the connection of PE feedwater piping; 3, the connection of Electric thermal smelting belt, shrink belt is applicable to the connection of PE class drainage pipe.Above-mentioned several Placements all need some special equipment when construction, and some need use electro-heat installation, are not suitable for field construction, and when construction is to the environmental requirement harshness of construction, the environment that needs dry cleansing, these all bring very big difficulty to construction.
And another kind of enlarging socket joint ways of connecting need adopt glue special bonding or adopt the seal ring resiliently deformable to seal, this mode is constructed does not need special equipment, and less demanding to construction environment, so be widely adopted, but its processing needs special equipment, and strict to enlarging technology, to guarantee the good fit of socket joint, as adopting the tubing that creep strain material (as PE) takes place easily for some, because radial contraction takes place in the two ends of its tubing easily, make the socket joint matching gap diminish, socket joint is difficulty relatively.Therefore, need the seal arrangement that a kind of pipeline connects, make between the pipeline and can fix well and seal.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming in the above-mentioned technology, a kind of sealing for tubing joints device of new mechanical formula is proposed, make pipeline not having carrying out rapid and reliable connection under good execution conditions and rugged environment or the weather, and be applicable to various tubing.
The purpose of this utility model is to be realized by following technological scheme:
This sealing for tubing joints device is made up of two Semicircular pipe threads, in be provided with sealing strip, the pipe thread both sides are provided with the connection set that connects two pipe threads, are characterized in that the inboard of pipe thread is provided with the rib of protrusion.
When there was ripple on the surface of pipeline, the parallel corrugation of above-mentioned rib and pipe surface may be stuck in the interval between ripple, prevents to be shifted between the pipeline; If pipe surface does not have lines or smooth, above-mentioned rib can be embraced the outer wall of pipeline, increases the friction between pipeline and the pipe thread, reaches to prevent the effect that is shifted between the pipeline.
Above-mentioned sealing strip is between two ribs in the middle of the pipe thread.
Above-mentioned sealing strip is to be made by flexible materials such as rubber, is used for fixing and seals the seam of two tubing.
The connection set of above-mentioned pipe thread is that a side is an articulated mounting, opposite side is that bolt device or both sides all are bolt devices, by fastening bolt pipe thread is pressed on the sealing strip, makes sealing strip that resiliently deformable take place between pipeline and pipe thread and connect and seal.
The edge of above-mentioned pipe thread is installed with pull-rod, and pull-rod is provided with bolt hole, makes that by bolton two pipe threads are sealed on pull-rod, and its effect is to make manufacturing process simpler.
Compared with prior art, advantage of the present utility model is:
(1) inboard of pipe thread is provided with the rib of protrusion, prevents to be shifted between the pipeline;
(2) be provided with sealing strip in the button, pipeline and pipe thread are sealed better;
(3) put with the connection set of pipe thread both sides pipeline can be carried out rapid and reliable the connection under good execution conditions and rugged environment or the weather not having.

Embodiment
Embodiment 1:
Sealing for tubing joints device of the present utility model is made up of two Semicircular pipe threads 2 shown in Fig. 1 and 2, in be provided with caulking gum band 3, one side of pipe thread 2 is provided with articulated mounting 7, be used to connect two pipe threads, opposite side is provided with bolt device, is used to make fastening, the sealing of pipeline.Shown in Fig. 3 and 4, the inboard of pipe thread 2 was provided with the rib 4 of 4 protrusions when the utility model was used for connecting tube, and rib 4 is parallel with the ripple 5 of pipe surface, can be embedded in the interval of 5 of ripples.
Sealing for tubing joints device of the present utility model the time is to reach like this to be connected and fixed and the purpose of sealed against leakage in construction: at first with two pipeline 1 horizontal alignments, the position of then caulking gum band 3 being aimed at two pipelines connection combination sets up, then the inboard being had the pipe thread 2 that protrudes rib 4 opens and is enclosed within on the caulking gum band 3, caulking gum band 3 to be positioned between the pipe thread 2 inboard two middle projecting ribs 4, prevent 3 displacements of caulking gum band, as shown in Figure 6, with bolt 6 pipe thread 2 is evenly locked then.Because the protrusion rib 4 of pipe thread 2 inboard both sides is parallel with the ripple 5 on pipeline 1 surface, may be stuck in the interval of 5 of ripples, just can embrace the outer wall of pipeline 1, prevent that pipeline 1 interface from taking place significantly to scratch, and the fastening force of bolt 6 makes pipe thread 2 that sealing strip 3 is oppressed, and makes sealing strip 3 produce resiliently deformables and with seal for pipe joints.
Embodiment 2:
Sealing for tubing joints device of the present utility model is shown in Fig. 5 and 6, and its implementation methods is identical with embodiment 1, and difference is to be provided with pull-rod 8 between pipe thread 2 and bolt 6, and without the articulated mounting among the embodiment 1.Its effect is to make manufacturing process simpler.
