An inclined plane is arranged on the inner side of the end of the clamping ring, and a plurality of protruding strips are arranged on the connecting pipe. The connecting structure is safe in connection and rapid in installation, the cost of pipes can be reduced, the operation is convenient, and a high practical value is provided.
Description
Technical field
The utility model belongs to the pipeline connection technology field, particularly a kind of linkage structure of temperature flexible pipe.
Background technique
In pipelines such as heating and supplying water, custom is used galvanized iron conduit or PPR pipe at present.Defectives such as galvanized pipe exists the installation and maintenance complicacy, is prone to get rusty, fouling are eliminated at present.The PPR tubing that replaces exists lower temperature resistance poor, hygienic issues be connected problems such as molten stifled.The America and Europe, PEX, PE_RT, PB, PAP etc. are to use wider flexible pipe.The domestic Placement that mostly still adopts thread cap to press collar, there are problems in this mode, as can not secretly burying; Screw thread is given up the throne under water impact; Pipe fitting is heavy, and cost is high; Problems such as installation efficiency is low.
The model utility content
The purpose of the utility model is to the problems referred to above, and a kind of linkage structure of structure improved flexible pipe is provided, and makes it have simple in structure, attachment security, characteristics such as easy to operate.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
The linkage structure of the sliding tight pipe fitting of this flexible pipe; Comprise a flexible pipe and the adapter that is connected with flexible pipe, the connecting end of flexible pipe is socketed in the adapter, and the external diameter of described adapter is not less than the internal diameter of flexible pipe; There is a collar in the outside of flexible pipe connecting end; Collar becomes cylindrical shape, and its internal diameter is not less than the external diameter of flexible pipe, collar and plastics with connecting end be that drive fit is connected.
The technological scheme that the utility model can also adopt:
The inboard, end of described collar is provided with an inclined-plane.
Adapter is provided with two above raised lines.
All there is the inclined-plane inboard, two ends of described collar.
Described adapter is a copper material.
Described collar is a plastic material.
The utility model is the plastic behavior that makes full use of flexible pipe, realize flexible pipe and take between be connected.Particularly, at first because the external diameter of taking over is not less than the internal diameter of flexible pipe, modes such as employing machine tool are opened the end of flexible pipe slightly, could the end of flexible pipe be socketed in the adapter; On flexible pipe, put collar then, and shift to the connecting end of flexible pipe.Because the internal diameter of collar just is not less than the external diameter of flexible pipe, when collar to flexible pipe connecting end, can be stopped.At last, adopt some machine tool compress collar, utilize the plasticity of flexible pipe, just the collar drive fit is placed on the flexible pipe.Flexible pipe firmly has been connected with adapter.In this structure, adapter can be played a supporting role.
Preferably an inclined-plane is set in the inboard, end of above-mentioned circle.Utilize this inclined-plane, make progressively banding flexible pipe of collar, to make things convenient for practical operation.
Usually, on taking over, be provided with 3-6 bar raised line,, prevent that flexible pipe breaks away from adapter in order to increase frictional force.
In the linkage structure of above-mentioned flexible pipe, described adapter in fact be on pipe joint or the valve with the attachment portion of flexible pipe.Obviously, the linkage structure of this flexible pipe can be used for being connected of flexible pipe and various metal joints or metal valve.
Compared with prior art, the advantage of the utility model is:
1. owing to adopting this structure that flexible pipe is not all changed with the internal diameter and the outside dimension that are connected the front and back collar of adapter; But rely on self plasticity of flexible pipe material; The flexible pipe end is deformed realize the drive fit that flexible pipe is taken over, so it connects very firmly.
2. in this linkage structure, except flexible pipe and adapter place, collar of an external application so structure is very simple, and has reduced the cost of pipeline.
3. when connecting, utilize the progressively mode of banding of collar, its tightening force size can be controlled, and is difficult for causing flexible pipe or adapter or adapter to damage or fracture phenomena; Simultaneously, operate quick and conveniently, have higher utility.
Description of drawings
Fig. 1 is the sectional drawing of the linkage structure of the flexible pipe that provides of the utility model.
The structural representation of linkage structure before connection of the flexible pipe that Fig. 2 provides for the utility model.
Among the figure, 1, take over; 11, raised line; 2, collar; 21, inclined-plane; 3, flexible pipe.
Embodiment
As shown in Figure 1, the linkage structure adapter 1 and the collar 2 of the flexible pipe that the utility model provides.Adapter 1 can be the adapter on the pipe joint, also can be an adapter on the valve.That is to say that this linkage structure both can be used for also can be applicable on the valve on the pipe joint.
Generally speaking, take over 1 external diameter be not less than the internal diameter of the flexible pipe 3 that will connect.Therefore, when connecting, the connecting end of flexible pipe 3 is opened, it is socketed on take on 1, adapter 1 is copper material with collar 2 in the present embodiment, and pipeline join strength, wholesomeness and high and low temperature resistance can be provided.
As shown in Figure 2, the internal diameter of collar 2 is the external diameters that are not less than flexible pipe 3.But took over for 1 last time when flexible pipe 3 connecting ends are socketed on, the external diameter of its end will be not less than the internal diameter of collar 2.
In the present embodiment, collar 2 all adopts metallic material to process with adapter 1, and metallic material can be copper, stainless steel etc., and collar 2 can be a plastic materials, like resistant to elevated temperatures PPSU, PSU or PEX material.After flexible pipe 3 ends are socketed on adapter 1, just can use machine tool compress collar 2, just collar 2 moves to the connecting end of flexible pipe 3.In this process, collar 2 can not deform.But through compress collar 2, just the end of flexible pipe 3 deforms.Like this, collar 2 with regard to banding flexible pipe 3, flexible pipe 3 firmly is connected with adapter 1.
In fact, behind collar 2 complete banding flexible pipes 3,, flexible pipe 3 is separated with adapter 1, only if part is wherein destroyed owing to be connected firmly.The inboard inclined-plane 21 that is provided with, collar 2 ends helps the extruding of collar 2.In the present embodiment, all there is inclined-plane 21 inboard, two ends of collar 2, makes no matter directivity of collar 2.As shown in Figure 1, be provided with some raised lines 11 on the surface of taking over 1.When flexible pipe 3 fully with after adapter 1 is connected, the inboard of flexible pipe 3 connecting ends also can embed in the gap between the raised line 11 slightly.Prevent that effectively flexible pipe 3 breaks away from adapter 1.
