Abstract
The utility model relates to a connection structure for a plastic pipe and a metal pipe. The connection structure comprises the plastic pipe and the metal pipe, wherein the metal pipe end is provided with a flange plate; the plastic pipe end is provided with an outward step; a movable flange plate is sleeved on the plastic pipe; the end face of the metal pipe is provided with an annular boss; and the movable flange plate is firmly connected with the flange plate through a bolt, so that the annular boss is pressed against the end face of the plastic pipe. Through the connection structure, the plastic pipe and the metal pipe are firmly connected and reliably sealed.
Description
Technical field
The utility model relates to the linkage structure between the pipeline, relates to the linkage structure of plastic tube and metal tube specifically.
Background technique
In the laying construction of municipal drainage, mine and chemical industry draining, irrigation and water conservancy irrigation, remote low-pressure water delivery, bonding or the electric smelting sealing-in of general employing between the plastic tube, then general welding or the flange of adopting connects between the metal tube, and, also do not have desirable method to solve at present for being connected between plastic tube and the metal tube.
Summary of the invention
The purpose of this utility model provides the linkage structure of a kind of plastic tube and metal tube, makes being connected firmly between plastic tube and the metal tube, and sealing is reliable.
The linkage structure of plastic tube described in the utility model and metal tube, comprise plastic tube and metal tube, pipe end is provided with flange plate, the plastics pipe end is provided with outside step, be set with moving flange plate on the plastic tube, the moving flange plate diameter of bore is provided with annular boss less than the stepped diameters of plastics pipe end at the metal tube end face, be connected by bolton between described moving flange plate and the flange plate, make annular boss be pressed on the plastic tube end face.
The cross section of described annular boss is triangular in shape.
The flange plate of pipe end is connected by bolton with moving flange plate on the plastic tube, because the moving flange plate diameter of bore is less than the stepped diameters of plastics pipe end, so moving flange plate will be pressed on the step end face of plastics pipe end, make the annular boss of metal tube end face embed the plastic tube end face, form a circle annular sealing strip.
Linkage structure described in the utility model is owing to be connected by bolton between moving flange plate and the flange plate, so make being connected firmly between plastic tube and the metal tube; Embed the plastic tube end face because the annular boss of metal tube end face compresses, form a circle annular sealing strip, so it is very reliable that being connected between plastic tube and the metal tube sealed.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the main pseudosection of the linkage structure of plastic tube described in the utility model and metal tube.
Embodiment
As shown in Figure 1, the linkage structure of this plastic tube and metal tube comprises plastic tube 1 and metal tube 7, metal tube 7 ends are provided with flange plate 5, plastic tube 1 end is provided with outside step 4, be set with moving flange plate 3 on the plastic tube 1, moving flange plate 3 diameter of bores are provided with cross section annular boss triangular in shape 6 less than step 4 diameters of plastic tube 1 end at metal tube 7 end faces, be fastenedly connected by bolt 2 between described moving flange plate 3 and the flange plate 5, make annular boss 6 be pressed on plastic tube 1 end face.
