Abstract
The utility model provides a novel T-shaped flexible pipe block of gas pipelines. The pipe block is composed of a pipe core, a trapezoid-shaped rubber ring which is sheathed on the pipe core, a flat washer and a screwing nut. When the utility model blocks pipe holes, as long as the screwing nut presses the trapezoid-shaped rubber ring which is positioned in a concave groove at the bottom of the pipe core through a flange ring at the other side of the flat washer near to the nut. The trapezoid-shaped rubber ring is deformed, and fully fills the pipe holes. Therefore, the utility model reaches the purpose of blocking pipe holes.
Description
The utility model provides a kind of novel gas pipeline T-shape flexible pipe plug.
At present, in the construction operation of gas pipeline, often need on pipe wall, hole and the tapping operation, so that special-purpose construction apparatus enters pipe interior.And after finishing whole construction operations of pipeline, take out corresponding special-purpose construction apparatus through boring, with the screw thread pipe close tube wall is holed again and carry out shutoff, recover the normal air delivery function of gas pipeline, the way that this kind holed with the shutoff of screw thread pipe close, on existing cast iron gas pipeline, generally adopted, this is because the tube wall of cast-iron pipe is thicker, more by tapping tooth number, adapted white paint and flax silk are as the thread pitch packing again, so the tightness of screw thread pipe close shutoff is good, satisfies the requirement of produced on-site construction fully.But, along with gas pipeline is used ductile cast iron material instead and is manufactured its pipe thickness of back and obviously change thin, the tooth number of tube wall boring back institute tapping is reduced, continue to use the screw thread pipe close not only not reach shutoff pore purpose, cause gas leakage, and the reduction of the pipeline mechanical strength behind the shutoff pore, be easy to generate pipeline accident hidden danger.
The purpose of this utility model provides the flexible pipe plug of a kind of novel gas pipeline T-shape, both has been applicable to the cast iron gas pipeline that tube wall is thicker, is applicable to the shutoff pore construction operation of the tube wall of ductile cast iron material manufacturing than thin gas pipeline again.
The utility model is achieved in that when screwing gland nut the inside and outside bead ring of another side of being close to the plain washer of nut pushes the trapezoidal rubber ring that places on the die bottom groove, makes the rubber ring distortion, fills and fills up pore, thus the shutoff pore.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Complete section plan view when figure-1 implements the shutoff pore for the utility model.
A cuts open to view in office when figure-2 implements the shutoff pore for the utility model.
Referring to Fig. 1, Fig. 2, inverse-T-shaped tube core (1), its side of being processed into, top tenon, interior tapping, middle external threading, the rounded groove in bottom also has stiffening rib (6), to increase mechanical strength.(2) for screwing nut, (3) are the plain washer that there is inside and outside bead ring a side.(4) be the trapezoidal sealing rubber ring of engage sleeves on tube core (1), peripheral size of bottom surface is limited in outer bead ring of plain washer (3) and the tube core of falling the T-shape (1) bottom groove on it.(5) for needing the gas pipeline tube wall of shutoff pore.When enforcement T-shape flexible pipe blocks the plugging hole, prepare an elongate handle in advance, after inverse-T-shaped tube core (1) top internal thread is connected, put in the pore that needs shutoff inverse-T-shaped tube core (1) is oblique, be inserted in trapezoidal sealing rubber ring (4) then, plain washer (3) (making the one side that has inside and outside bead ring press close to trapezoidal sealing rubber ring (4)) screws in nut (2) again.Like this, screw nut (2), the inside and outside bead ring of plain washer (3) pushes trapezoidal rubber ring (4), and under the spacing and co-extrusion effect of inverse-T-shaped tube core (1) bottom groove, trapezoidal rubber ring (4) distortion is filled and filled up the pore that needs shutoff.
According to the size of gas pipeline tube wall boring, match the flexible pipe plug of T-shape of corresponding size, just can reach the purpose of shutoff pore anti-leak.And self intensity of the flexible pipe plug of T-shape, be enough to guarantee the mechanical strength of pipeline body behind the shutoff pore make construction operation safe and reliable.
The utility model adopts trapezoidal rubber ring to carry out flexible shutoff pore, thereby it is irrelevant with the wall thickness of gas pipeline, whether having attacked screw thread and aperture with boring, to lose circle irrelevant, need not other during shutoff simultaneously and fill auxiliary material, thereby the flexible pipe plug of novel gas pipeline T-shape not only can substitute original screw thread pipe close, and surpassed original screw thread pipe close on tightness, the mechanical strength safety reliability in application area and ease of use, anti-letting out.The every test in laboratory has all confirmed above-mentioned conclusion.
Claims (3)
1. one by inverse-T-shaped tube core (1), tightening nut (2), and there are the plain washer (3) of inside and outside bead ring and the flexible pipe plug of gas pipeline T-shape that trapezoidal sealing rubber ring (4) is formed in one of them side, it is characterized in that:
A. the side of being processed into, inverse-T-shaped tube core (1) top tenon, interior tapping,
B. attacked outside thread in the middle of the inverse-T-shaped tube core (1),
C. the rounded groove in inverse-T-shaped tube core (1) bottom, and stiffening rib (6) is arranged.
2. the flexible pipe plug of T-shape according to claim 1 is characterized in that there is inside and outside bead ring a side of plain washer (3).
3. the flexible pipe plug of T-shape according to claim 1 is characterized in that the peripheral size of the last bottom surface of trapezoidal sealing rubber ring is limited in outer bead ring of plain washer (3) and inverse-T-shaped tube core (1) bottom groove.
