Abstract

The invention discloses a double taper pipe joint, and belongs to the machinery. When a plastic hose A and a plastic hose B are butted, a thread bushing (1) and a taper sleeve (4) are respectively covered on the plastic hose A, a taper sleeve (3) is covered on the plastic hose B; the plastic hose A and the plastic hose B are respectively covered on both ends of a double taper pipe (2) to be wedged and expanded into a taper mouth (5) and a taper mouth (6), the taper sleeve (3) and the taper sleeve (4) are moved to close up to ensure the thread bushing (1) and the taper sleeve (3) are screwed, the taper sleeve (3) and the taper sleeve (4) are driven to close up when the thread bushing (1) and the taper sleeve (3) are unceasingly screwed, the tapers of the taper sleeve (3) and the taper sleeve (4) closely wedge the taper mouth (5) and the taper mouth (6) and are extruded and sealed with the lined double taper pipe (2). In a similar way, the invention can be used for a welded steel pipe the diameter of which is more than 1m, the welded steel pipe is rolled by a rolling machine, has a length less than 2m, is welded into a fixed size by connecting six steel pipes, is welded with a big flange connected by bolts. If the invention is used: a fixed size pipe A is covered with the thread bushing (1) and the taper sleeve (4), and one end of the pipe A is welded with the preprocessed taper mouth (5); a pipe B is covered with the taper sleeve (3), the taper mouth (6) is welded just like the pipe A; the pipes are simply arranged by covering the double taper pipe (2) and screwing the thread bushing (1). The double taper pipe joint is suitable for hoses, thin-wall metal pipes, large welded pipes, and also for glass and hard plastic pipes.

Description

Bipyramid pipe joint

The present invention is a mechanical field, a kind of bipyramid pipe joint.

The delivery hose of solar water heater, when one, two layers the user in the end is guided on six tylophora florlbundas tops, because of hydraulic pressure higher, often there is breaking property to leak, repairs the people lower semisection is renewed, with roughening splicing, time-consuming, and, leak once more soon because of being weakened by roughening place tube wall strength.This makes the people associate this kind of a hose coupling.In addition, my application utilizes the aspect more to need the hose coupling and the big pipe joint of thin-wall metal of convenient application about solar energy.

Dig button as figure thread bush 1 left end, fasten the flange of tapered sleeve 4 movingly, the other end cooperates with tapered sleeve 3 with screw thread; In the middle of the double taper pipe 2 is the tool withdrawal groove that adds man-hour, and there is the tapering of same size at two ends.If hose A and B, earlier thread bush 1 and tapered sleeve 4 strings are enclosed within the outside of A, again tapered sleeve 3 strings are enclosed within the outside of B, then the two ends of the mouthpiece cover of A, B, dilated

formation cone ports

5 and 6 by double taper pipe 2 wedgings in double taper pipe 2; At last

tapered sleeve

3 and 4 opposite directions are shifted near,

tangible cone ports

5 and 6 male cone (strobilus masculinus)s are locked, turn thread bush 1 meshes with the outside thread of tapered sleeve 3, when continuing to screw thread bush 1 again, just it is approaching mutually to drive

tapered sleeve

3 and 4, make their tapering

wedging cone ports

5 and 6, and push close joints with the double taper pipe 2 of liner; If the present invention is when being used for the high-pressure metal big pipe, and double taper pipe 2 also is subjected to very big interior hydraulic pressure, dilates trend, makes to paste closelyr with

cone ports

5 and 6.

I once witnessed the big steel pipe that the reservoir of managing Φ＞1m is guided to water utility, be rolled into the long pipeline section of not enough 2m by plate bending rolls, again with 6 sections welding spreadings, the big flange (dish) that two ends are burn-on thick again, the turning end face screws with tens of high strength king-bolts on every secondary flange during installation.Replace flange, liner if use the present invention instead, installing in trench can be convenient a lot: the people can stand on the trench springboard suitable with external diameter and the hole among the figure 10 of a brachymemma pipe G (not having figure), come the tight thread bush 1 of plate, dynamometer demonstration on the spanner handle that the weldering of pipe G upper end is lived reaches design load at once, this is than installing in the trench, all must dig a hollow place at each secondary flange place, go below being drilled in tens of king-bolts being wrenched one by one on every secondary flange much better for the people.If use bipyramid pipe joint instead: put tapered sleeve 4 and thread bush 1 welding the big steel pipe A guest performer of spreading earlier to scale (very little); The big steel pipe B string long at scale puts tapered sleeve 3, burn-ons the finished

product cone ports

5 and 6 that rolls in advance just at A pipe pipe end and B pipe pipe end again.Be inserted in double taper pipe 2 during installation, screw just completion of thread bush 1.

Illustrate: 1, hole 10 is uniform through holes on the cylndrical surface of thread bush 1, can make driving hole double as sight hole; 2, thread bush 1 and the screw thread that tapered sleeve 3 cooperates are used for unessential tubule joint available standards screw thread; Be used for the high pipe joint of big, the interior pressure of caliber, should use buttress thread, it screws frictional force (compared with other tooth forms) minimum when stressed, can bear the shearing force maximum; 3

tapered sleeves

3 and 4 small end profile are just the same, as C-C view (only drawing half), can do the spanner depressed place because with

cone ports

5 and 6 wedge real before just in case rotate, available spanner is pulled; 4, the stress surface movingly of thread bush 1 and tapered sleeve 4, and with the screw thread of tapered sleeve 3 on should be coated with spot lubrication fat.

In the drinking-water pipe lining sheath is often arranged now, if external galvanized layer in the double taper pipe of bipyramid pipe joint 2, or the food grade plastic layer, utilize these aspect hardness low, cooperate close joint self adaptive more reliable.

The experiment, chemical industry some need use glass tube, the glass tube local heating is done plug with double taper pipe 2, is moulded

cone ports

5 and 6; During A and B pipe dock, except double taper pipe 2 should be used neutral Pyrex, other all available engineering plastics of part of remainder, or stainless steel or copper material etc.

Positive effect: 1, use glass tube, hard plastic pipe, without welding, attaching and dismounting can be used repeatedly; 2, the heavy caliber steel plate Weldable Steel (liquid pipe or gas tube) of welding spreading can significantly improve installation efficiency, preferably applies self adaptive good knitting layer outside the double taper pipe 2, can be more reliable; 3, solar energy utilizes in the Development Engineering, all uses thin metallic tubd, difficult system screw thread, and the elastic seal ring engaging force is too little, is not suitable for the temperature of the bigger thin metallic tubd of caliber and 300-400 ℃, so be fit to use bipyramid pipe joint.

Description of drawings:

Only use a width of cloth figure: bipyramid pipe joint profile and partial sectional view; In broken section, shown entire infrastructure.The C-C on right side shows more that to the cross section this place's profile slightly is the hexagonal shape.
