Background technique
Traditional pipe connecting method has screwed connection, welding (comprising that the hot melt connection connects with gluing), flange to be connected three kinds of connecting means, all be to bear two kinds " functions " by one " structure ", as " screw thread " in the screwed connection method, it is promptly born " connection " function and bears " sealing " function again; " weld seam " in the welding method also is promptly to bear " connection " function to bear " sealing " function again; " flange plate " in the flange connecting means also is to bear two functions simultaneously, and the structure of this " uniting two into one " can produce the consequence of " attending to one thing and lose sight of another " naturally, so pipeline junction often leaks.At present, disclosed " locking of flexible sealing socket joint " pipe connecting method is that theoretical change of pipeline connection that will " unite two into one " becomes " being divided into two ", two functional separations in the pipeline connection are born respectively by two members: " sealing " function is born by one " flexible sealing ring ", " connection " function is born by " socket joint locking " structure, so just accomplished " division of labor is clear and definite ", solved the leakage difficult problem that pipeline connects.
" articulated Fast-mounting tube fitting " usefulness of China Patent No. ZL01241612.6 be " nut check connecting means ", the uropore cover of locking nut is pressed on the tapered slope of cone locking ring (profile is coniform, the interior columniform ring body that is), to cone locking circulating application plus-pressure, the cone locking ring has been embraced pipe with regard to hoop tightly, locking nut locks by the cone locking ring and connects pipe, realized being connected between pipe and the pipe.The cone locking ring is a taper garden ring by the longitudinal opening disconnection, can adapt to the tolerance variation of various different size tube outer diameter sizes, but but influence the integrity of locking ring, has reduced the coupling mechanism force of locking ring.Simultaneously in order to prevent to advance before the cone locking hoop, the flexible rubber seal ring that joins with it expands out from the opening distortion of locking ring, just must between cone locking ring and seal ring, add a pad, not only processing trouble, and strengthened the pipe link cost.
The patent of invention of China Patent No. ZL200510045875.4 discloses a kind of " connecting means of wedged cone shaped tooth block combination locking pipe ", and use therein is " flange locking connecting means ".In this connecting means, the taper inner hole sleeve of locking flange is pressed in the oblique back of taper of wedged cone shaped tooth block, wedged cone shaped tooth block is exerted pressure, the teeth of wedged cone shaped tooth block inboard are tightly the pipe of having nibbled just, the locking flange comes to this to lock by wedged cone shaped tooth block and connects pipe, realizes being connected between pipe and the pipe.Several wedged cone shaped tooth blocks are to be inlaid on the taper block teeth support, the hard teeth of the wedged cone shaped tooth block inboard sub-crust 20-50 of the inlet pipe micron of nibbling is dark,, the locking connection power of pipeline destroyed the corrosion protective covering of pipe appearance though having strengthened, the working life of having reduced pipeline; Many in addition individual block teeth supports have also increased link cost and trouble have been installed.
Summary of the invention
The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, to provide a kind of processing simple, quick and easy for installation, can reduce the pipeline link cost, satisfy the cone locking ring of the shirt rim Tapes gap of corrosion protection requirement.
Technical solution of the present invention is: a kind of steel ball cone locking ring, by the inboard made from rubber or plastics is that cylindrical, the outside is one section cylindrical and one section annular solid that taper shape combines, several steel balls that are uniformly distributed along the circumference are inlayed at place, the middle part of the side one section of the taper shape of described annular solid, clear spacing between the described steel ball is 5 ~ 30mm, and described steel ball will be higher than 10 ~ 50 microns of the outer surfaces at the place, one section middle part of the side of taper shape of annular solid.
Annular solid of the present invention is to make with elasticity such as rubber or plastics and the bigger material of friction factor, the several steel balls of embedding that are uniformly distributed along the circumference at the place, one section middle part of the side of taper of annular solid, the tolerance variation that both can adapt to different size tube outer diameter size, can increase again and pipe between frictional force (coupling mechanism force), can satisfy simultaneously requirement of strength again to annular solid, the steel ball of being inlayed can at first support " locking nut " or " locking flange ", transmit " locking nut " or " locking flange " locking pressure, realized firm locking linkage function pipe to pipe.Disconnected the cone locking ring in ZL01242612.6 " articulated Fast-mounting tube fitting " individual opening has been arranged, so just need between cone locking ring and seal ring, not add a packing ring again; The pipe of also nibbling the wedged cone shaped tooth block in ZL200510045875.4 " connecting means of wedged cone shaped tooth block combination locking pipe " destroys the corrosion protective covering of pipe appearance and reduces pipeline working life.
It is simple, quick and easy for installation that the present invention has processing, can reduce the pipeline link cost, satisfies the corrosion protection requirement, prolong advantages such as pipeline working life.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.As shown in Figure 1, in the pipe connecting method of nut check or flange locking, the inboard of selecting rubber or the plastics suitable substantially with rubber elasticity to make according to the function of use of want connecting tube is that cylindrical, the outside is one section cylindrical and one section annular solid 1 that taper shape combines, and different is on the same section at the place, the middle part of the side of one section of the taper shape of described annular solid 1 uniform inlays several steel balls 2 with prior art.During processing and fabricating, earlier steel ball 2 is arranged in uniformly the position, place, the mould annulus middle part of the side of taper section with the clear spacing of 5 ~ 30mm, between mould, squeeze the hot melt shaping raw material that (pressure) annotates rubber or plastics again, steel ball 2 just is embedded in the place, the middle part of the side of one section of annular solid 1 taper shape, steel ball 2 outer rims and annular solid 1 cylindrical inner wall surfaces are tangent, and steel ball 2 outer rims exceed the conical middle part of the side of annular solid 1 and locate 10 ~ 50 microns of outer surfaces.
The same prior art of installation method can be at the pipe fitting of various flexible sealing socket joints locking: supporting use in the link of pipes such as straight-through, elbow, threeway, four-way, reducing, spigot, socket, flanged joint, plug.
Because rubber or the plastics suitable substantially with rubber elasticity have scalability, the tolerance dimension that can adapt to various different size tube outer diameter changes; Annular solid 1 inwall and steel ball all join with tube outer wall, the friction factor of rubber or the plastic material suitable substantially with rubber elasticity is greater than existing metal tube and hard plastic pipe, and the steel ball surface is slick and sly, though friction factor and existing metal tube surface are quite, but be stuck in tube surface in the next meeting of pressure, promptly increase frictional force and can not destroy the pipe epidermis again, realized the firm locking of pipe is connected.
