Summary of the invention
The utility model is to provide a kind of metal heavy wall delivery pipe that breaks to repair pipe joint fast, and this pipe joint can be under the prerequisite that needn't cut out fluid delivery valve, realizes breaking or the quick reparation of the high-pressure liquid metal delivery pipe of seepage; It is convenient to repair on-the-spot installation, only needs 3-5 minute; Connecting tube adopts the resiliently deformable of three layers of Stainless Sheet Steel and the method for seal ring combination, realizes sealing, good leak-proof effect; The fastening dependence nut of connecting tube realizes that fitting operation easily and fast.
For achieving the above object, the technical solution of the utility model is: a kind of metal heavy wall delivery pipe that breaks is repaired pipe joint fast, comprise interior pipe, middle pipe, outer tube, pipe clamp, be characterized in: interior pipe, in pipe, outer tube is that the corrosion resistant plate of 0.5-1mm surrounds by thickness, it vertically leaves the vertical masonry joint that width is 0.5mm; In the pipe, middle pipe, outer tube embed the cooperation socket successively, and interior pipe, middle pipe, the vertical masonry joint on the outer tube be 120 ° uniform; Interior pipe, middle pipe and outer tube extrude the annular fixed groove of oriented pipe outer lug in two ends; Pipe clamp is pressed with outside annular groove by the opening circular ring that steel plate bending is shaped in the empty opening circular ring, and the opening both sides of hollow open circular ring respectively are provided with one and tighten up piece, and two are tightened up connecting bolt and nut are installed between the piece; A pipe clamp respectively is equipped with at the outer tube two ends, and the annular fixed groove of the projection of outer tube just in time embeds in the annular groove of pipe clamp; In the annular fixed groove in the interior pipe seal ring is housed, in the annular fixed groove in 2/3 of the line footpath of seal ring embeds in the pipe.
Interior pipe, middle pipe and outer tube form a folding circle at all outside flanging of the mouth of pipe at two ends; The thickness of pipe clamp is 2-3mm.
The utlity model has following beneficial effect:
(1) under the prerequisite of not closing fluid delivery valve, realizes the quick reparation of breaking or the metal of seepage is carried thick walled tube;
(2) repair on-the-spot installation conveniently, time saving and energy saving, only need 3-5 minute;
(3) connecting tube adopts the resiliently deformable of three layers of Stainless Sheet Steel and the method for seal ring combination, realizes sealing, good leak-proof effect.
(4) the fastening dependence nut of connecting tube is realized, fitting operation is convenient.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1 to Figure 3, the metal heavy wall of the present utility model delivery pipe that breaks is repaired pipe joint fast, pipe 1, middle pipe 2, outer tube 3, pipe clamp 4, seal ring 5, hex head bolt 6, hexagon nut 7 in comprising.
(1) pipe 1, middle pipe 2 and outer tube 3 surround by the corrosion resistant plate of thickness for (0.5-1) mm in, and leave vertical vertical masonry joint that width is 0.5mm.After the assembling, interior, in, the vertical masonry joint on outer three layers of pipe be 120 ° uniform.
(2) pipe 1, middle pipe 2 and outer tube 3 all extrude to the annular fixed groove 10 of managing outer lug in two ends in.During assembling, manage 2 during interior pipe 1 embeds, middle pipe 2 embeds outer tube 3, and the annular fixed groove 10 of the projection of outer tube 3 just in time embeds in the annular groove 9 of pipe clamp 4, and this has just prevented the changing of the relative positions between the tube and tube.
(3) in the fixed groove 10 of pipe 1 seal ring 5 is housed in, in 2/3 embedded groove in its line footpath, delivery pipe is understood the crush seal circle after being inserted in pipe joint, and forms interference fit with it, plays the effect of delivery pipe being carried out axially locating.
(4) pipe 1, middle pipe 2 and outer tube 3 form a folding circle at all outside flanging of the mouth of pipe at two ends in, make the internal diameter of the mouth of pipe that increase be arranged slightly, are convenient to delivery pipe two and are inserted in pipe joint fast.
(5) pipe clamp 4 is that thickness is the opening circular ring of the steel plate bending shaping of (2-3) mm, be pressed with outside annular groove 9 in the opening circular ring and (see Fig. 4,5), the opening both sides of opening circular ring respectively are provided with one and tighten up piece 8, two are tightened up to be equipped with between the piece and connect hex head bolt 6 and hexagon nut 7, compare with general pipe clamp, have the big and advantage of uniform of package power.
(6) when feeding high-pressure liquid in the pipe joint, the extruding that interior pipe 1 is subjected to fluid can produce resiliently deformable makes internal diameter that increase be arranged slightly, thereby centering pipe 2 produces extruding.In like manner, in pipe 2 extruding outer tubes 3,3 pairs of pipe clamps of outer tube 4 produce tension forces, tighten nut 7 on the pipe clamp 4 can make interior, in, outer three layers of pipe rely on resiliently deformables to pack tightly, can prevent effectively that high-pressure liquid from leaking, thereby reach the break purpose of pipe of quick reparation metal heavy wall.
Concrete Application Example:
To break in the delivery pipe or one section of the part of seepage excision, to repair the pipe joint two ends then and be inserted in the two ends of the pipe that breaks from cutting section respectively, (see figure 6) is tightened the nut on the left and right pipe clamp then fast, has promptly finished breaking in the delivery pipe or seepage quick reparation partly.
