Moreover, the method has the advantages of good sealing performance, reliable quality, no leakage, convenient and rapid installation, no need of any installing devices, saving of device cost, increase of work efficiency for 3 to 5 times, shortening of construction period, saving of labor cost and reduction of engineering cost.
Description
Technical field
The present invention relates to a kind of pipe connecting method, particularly relate to the connecting means of a kind of pipeline elasticity.
Background technique
Pipeline has become the lifeline of modern civilization society, and it has occupied the first place of the world's five big defeated thing carriers; The defeated thing amount that surpasses railway transport, highway transport, water route transportation, air transportation because the defeated object space of pipeline just, safety, cheapness, freight ton-km is minimum.So Future Society pipeline industry will obtain great development, and the continuous defeated thing scope that enlarges pipeline of meeting, will develop into from delivering liquid, gaseous state goods and materials and carry congee shape, powdery, particulate material.But all rigid conduits connect the problem that all has a distortion on the whole world: as temperature deformation, and pipeline elongation when temperature is high, pipeline will shrink when temperature was low; Being embedded in underground pipeline is usually broken by drawing crack because of following subsoil settlement; Pipeline was damaged by any torsional deformation of powerful seismic force when earthquake took place, and impaired fuel gas pipeline leakage can cause fire or set off an explosion.In order to solve the distortion of pipeline, what adopt the earliest is to establish the bend pipe expansive force that a stewing there emerged a " several " font on the certain distance of pipeline extensions, flexible with the distortion that solves pipeline, pipe diameter is thick more, this crankle big more, the construction trouble, the space that accounts for is big, especially being provided with this large deformation at indoor pipeline turns round and just is difficult to see, " sleeve expansive force " appearred again in succession, the sleeve pipe sleeve of the comparison precision of i.e. two processing gets up, but it can only be flexible in rectilinear direction, is that traditional flange plate method is connected between the pipe of this " sleeve expansive force " and both sides, owing to the structure reason, this " sleeve " formula expansion bend often leaks, and because it does not possess the performance of bearing pipeline inclination corner, so it still can be turned round and sticks up and damage when the sedimentation of pipeline inequality occurring.
This shows that there are many defectives really in above-mentioned more existing pipe connecting methods, can not satisfy any distortion of pipeline, suddenly wait to be improved.
Can satisfy the pipeline requirement of distortion arbitrarily in order to solve pipe joint, a lot of experts and scholars there's no one who doesn't or isn't seek solution painstakingly with relevant manufacturer, but do not see for a long time has suitable deisgn product to be finished by development always, and also not seeing has the similar techniques paper to be delivered.And existing product can not satisfy usage requirement, and this obviously is the problem that the anxious desire of relevant dealer solves.
In view of the ubiquitous defective of above-mentioned existing pipe connecting method, the inventor is summing up on the basis of being engaged in pipeline connection technology research and practice for many years, through research innovation repeatedly for many years, design repeatedly and pilot sample, repeatedly model engineering test and test, finally successful invention has gone out the connecting means of pipeline elasticity, it can adapt to the pipeline that is attached thereto and be out of shape arbitrarily: stretching, compression, any direction curve distortion at any angle, it can not damage, and good seal performance, reliable in quality, no seepage and no leakage.Quick and easy for installation in the construction, reduce cost of labour, without any need for erection unit, save installation cost, improve 3～5 times of work efficiency, shorten installation period, reduce engineering cost.
