Abstract
The utility model provides a pipeline-joining device, which comprises a press cover (1), a non-metal sealing member (2), a joining outer sleeve (3), etc. The press cover and the sealing member of the pipeline-joining device are respectively provided with an inosculating inclined plane, and under the function of the press cover, the inclined plane generates wedge-shaped force to join and seal the pipelines. The pipeline-joining device can be directly used, without the need of screw threads being processed on the pipelines on the spot, which facilitates operation, saves time and labor, and increases efficiency over one and a half times. The pipeline-joining device is suitable for joining pipelines such as running water pipes, gas pipes, petroleum pipes, plastic pipes, metal pipes, etc., which provides convenience to users.
Description
The utility model is about the pipeline coupling arrangement.
Up to now, to connect the requirement to pipe fitting be sealing and fixing for general pipeline.When it is installed and used, pipe fitting is processed the garden taper pipe thread, then be wrapped with sealing strip, again two pipe fittings is tightened with the screw thread operated implement.And must use the screw thread operated implement during on-the-spot the installation.Time-consuming when the shortcoming of this pipeline connecting mode is machining screw, effort.Particularly user's use can bring great inconvenience.
Shortcoming at above-mentioned pipeline connects the object of the present invention is to provide a kind of pipeline coupling arrangement.During use, do not need the on-the-spot machining screw of pipe fitting, directly use the connection pipe arrangement, sealing and fixed effect are splendid.
Pipeline coupling arrangement of the present invention is made up of gland (1), nonmetal Sealing (2), connection overcoat (3) etc.Fig. 1 is the structural drawing of pipeline coupling arrangement of the present invention, also is embodiments of the invention.
Among Fig. 1, the inclined-plane is processed on gland (1) top, the external diameter machining screw, its effect is that the gland with two ends screws, and squeeze sealing member (2), the inclined-plane that also be processed on the top of Sealing (2) and gland (1) matches, gland (1) produces wedge shape power on the inclined-plane when screwing, under the effect of wedge shape power, compress pipe fitting after making nonmetal Sealing (2) produce deformation, play seal action.And wedge shape power produces can bear certain axial force after axial rub connects pipe fitting.And two ends gland endoporus and pipe fitting are Spielpassung, make pipe fitting produce radial constraint moment, play fixation.The pipeline that the pipeline coupling arrangement can be used to connect the garden pipe of metal tube, plastic tube and various materials connects.As the connection on running water pipe, gas pipe, petroleum pipeline and acid, alkali, oil and road, can select different metallic material and sealing material for use according to different purposes.Can select malleable cast iron for use as gland, overcoat, acid-and base-resisting stainless steel etc., Sealing can be selected teflon for use, asbestos rubber etc.
The mounting type of pipeline coupling arrangement of the present invention is as follows: Sealing (2) packed in the skewed slot of overcoat (3), and in the endoporus of again pipe fitting at two ends is packed into gland (1) and Sealing (2), the last threaded gland of rotating band.As 3/4 inch common pipe fitting is installed, and Sealing (2) can adopt polyethylene from high pressure process, and its tension limiting value is 1428kgf, and tensile strength is 375.94kgf/cm.
Pipe line joint device of the present invention and traditional pipeline connecting mode relatively have obvious advantage: 1, save time, laborsaving, pipe fitting does not need on-the-spot machining screw, therefore can raise the efficiency over half. 2, this device is easy and simple to handle reliable, brings great convenience to the user.
Claims (3)
1, a kind of tap water pipe line, gaspipe line, petroleum pipeline, acid, alkali, oil pipe line coupling arrangement of being used for, it is characterized in that the pipeline coupling arrangement is made up of gland (1), Sealing (2), connection overcoat (3), gland of pipeline coupling arrangement (1) and Sealing (2) have an inclined-plane that matches, under the effect of gland, the inclined-plane produces wedge shape power and plays pipeline connection seal action.
2,, it is characterized in that it is Spielpassung that the gland endoporus connects with pipe fitting according to the described pipeline coupling arrangement of claim 1.
3, according to the described pipeline coupling arrangement of claim 1, it is characterized in that gland (1), connection overcoat (3) can adopt malleable cast iron, acid-and base-resisting stainless steel and composite etc., Sealing (2) can be selected teflon for use, materials such as asbestos rubber, polyethylene from high pressure process.
