Abstract
The utility model aims to provide a pipe telescopic joint for adjusting lengths of two pipes through stretching out and drawing back, and belongs to the field of building pipes. According to the pipe telescopic joint, a telescopic pipe is inserted into a telescopic casing pipe, one end of the telescopic casing pipe serves as a packing chamber with internal threads, and the other end of the telescopic casing pipe serves as a short joint with the inner diameter less than the inner diameter of the telescopic casing pipe; the other end of the telescopic pipe is provided with a telescopic pipe flange, and the end of the short joint is provided with a short joint flange; the inner portion of the packing chamber is filled with soft sealing packing, the telescopic pipe is sleeved with a compression screw, and the lower end of the compression screw is inserted into the inner portion of the packing chamber and provided with external threads matched with the internal threads of the packing chamber; a screwed hole is formed in the outer wall of the compression screw. The pipe telescopic joint is simple in structure and convenient to install and use, due to the adoption of the telescopic function of the telescopic pipe and the telescopic casing pipe, the required length can be set according to actual requirements, then sealing is performed through the packing, and the pipe telescopic joint can achieve the length telescopic adjustment function and also achieve the perfect sealing function.
Description
Technical field
The utility model belongs to building pipe field.
Background technique
Various place that is applied in of pipeline is used, for the ease of transportation, the length of general pipe can be not oversize, the existence that so just needs pipe to connect, and be commonly used always, yet pipe connects with the sealing problem that is connected of pipe and generally connects and the linking screw thread place of pipe adds the sealing materials such as fiber crops at pipe sometimes, yet due to hydraulic pressure, the factor such as artificial, may cause certain link poorly sealed.Or if pipe installation is longer, some position needs short tube to be connected, and now, just in case mistake in computation or modification will be destroyed this short tube and again be cut enough short tubes, will cause waste.
Summary of the invention
The purpose of this utility model is to provide a kind of by two short pipeline expansion joints of pipe range of telescopic adjustment.
It is inner that telescopic pipe of the present utility model inserts telescopic tube, and telescopic tube one end is for being with female packing cavity, and the other end is the pipe nipple that internal diameter is less than telescopic tube internal diameter; The telescopic pipe the other end has telescopic pipe flange, and there is pipe nipple flange pipe nipple end; The inner filled soft stuffing box packing of packing cavity, has at telescopic pipe overcoat the spiral of pressing, and presses spiral lower end and is inserted in packing cavity inside, and press the outside thread that spiral lower end has the internal thread with packing cavity to match; Pressing the hole that spins on the outer wall of spiral.
The utility model is simple in structure, easy to install, due to the telescopic pipe adopting and the Telescopic of telescopic tube, just can situation according to actual needs set Len req, then by filler, seal, reached the telescopic adjustment function of length, can reach perfect sealing function again.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
During use, first telescopic pipe is inserted to telescopic tube inside through pressing spiral, then by pressing spiral, to the telescopic pipe flange direction of telescopic pipe, stir as far as possible, packing cavity is abdicated completely, then to packing cavity inside, dose filler, fill up as far as possible, then packing cavity is inserted in the lower end of pressing spiral, and spiral is pressed in rotation, under the effect of screw thread, press the inner propelling of screw packing cavity, make filler compacted simultaneously, after cannot turn pressing spiral, stop, now filler is not only by the clearance seal between telescopic pipe and telescopic tube, side is firmly controlled telescopic pipe and telescopic tube simultaneously, both played seal action, play again fastening effect.
