Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tube joint or tube support structure in which fluid is injected or filled into the cheep to maintain airtightness or liquidtightness.

This conventional Japanese cypress pipe joint or pipe support structure (hereinafter simply referred to as the pipe support structure) is used when connecting two completely fixed pipes or when applying force in the axial direction of the connected pipes. However, it is suitable when a large axial force is applied to the pipes to be connected, when the frictional resistance force on the tube surface is small, or when a force in the withdrawal direction is applied due to deformation movement. For this, do 7 lunges between the tubes.

They are connected using rigid bodies such as screws, and airtightness and liquid tightness are maintained using rubber plates, O-rings, mechanical seals, etc. However, the construction has the disadvantage that the machining of the connection work, such as welding the seven flange, threading, and fastening a large number of bolts and nuts, is extremely troublesome.Especially when flanges are used, it is difficult to transport and store the pipe. There is a drawback that not only is it bulky, but it is also heavier. In addition, since the pipes to be connected are completely fixed to each other, it is not possible to adapt to physical forces such as temperature changes, ground pressure, water pressure, wave motion, etc. that are applied depending on the piping location, and these can lead to damage.

Since the seal for filling the fluid is extremely simple, the present invention makes use of its characteristics and can maintain reliable connection and airtightness and liquidtightness by resisting and adapting to seal strength and physical force. The aim is to provide pipe support structures in India or pipe support structures.

The gist of the present invention is as shown in the figure.

A sealing gap 3K formed by inserting the inner tube 1 to be connected or supported into the socket tube 2, a reinforced Q-pro with an elongated circular cross section and an inlet 4 for fluid filling, and an axial direction. An elastic tube 6 which suppresses the elongation of the elastic tube 6 is superposed to form a compound tube shape, and one elastic tube 6 KII [stop ring 6 for imparting a wedge action via a connecting or mechanism elastic member 7 is formed. 1 is a pipe intrusion or pipe support structure characterized in that it is attached to a pipe.

! Figure 8'1 shows the elastic tube 6 parts II! The fixing ring 9 is configured to be in contact with the stop ring 8, and the stop ring 8 is in a trumpet shape, and the fixing ring 9 is in contact with the inner surface of the trumpet-shaped stop ring 8 and is screwed to the outer peripheral surface of the internal tube 1. This prevents the tube from coming off the inner intubation tube 1.

Reinforced Cheve! j#'i1 Reinforcement by using a rubber material with high strength or by incorporating or incorporating a canvas sheet (

h. Either use a material that suppresses the elongation in the axial direction, in other words, use a material that is difficult to elongate in the axial direction, or use a material that does not elongate in the axial direction.
A large number of these may be arranged parallel to the axis and along the circumference so that they do not extend in the axial direction. It goes without saying that in this case, instead of the thin metal plate 18, a metal wire, a hard glass plate, a plastic wire, etc. can be used. ! l! Figures 3 to 111!5 show O as the elastic member 7 between the elastic tube 5 and the stop ring 8.
This is a configuration with a ring interposed. Particularly, Fig. 3 shows a configuration in which an O-ring is interposed between the stop ring 8 and the fixing ring 9, and a campus sheet 17 is interposed between the reinforced chapel and the surface of the internal tube 1, and Fig. 4 shows the structure in which the stop This is a configuration in which the O-ring wire diameter between the ring 8 and the elastic cylinder 6 is small. In FIG. 5, the stop ring 8 is shaped like a horn with a throat, and the O-ring wire diameter as the elastic member 7 is made small so that it comes into contact with the inclined outer surface of the horn.

The above @1 figures to @5 figures all show the embodiment A group in which the stop ring 8 is in contact with one end of the elastic tube 6 directly or through an elastic member, and the fluid filling inlet 4 is in the socket tube 2. Let it emerge from the cut size 11 formed at the end of the tube.

Next, Example B group is shown in Fig. 6, in which stop rings 8 are provided at both ends of the elastic tube 6, and the fluid filling inlet 4 is made to emerge from the elongated hole 12 bored in the end surface of the socket tube 2. ~! This will be explained in FIG.

11!6 and 7 show a stop screw 13 in which an elastic member 7 is integrally formed at one end of an elastic cylinder 6, and a pack stop ring 8' is attached to a socket pipe 2 at the other end of the elastic cylinder 6.
It is configured to prevent the elastic cylinder 6 from retreating,
@7 Figure 17 is the campus sheet.

Figures 11 and 8 show a structure in which the elastic cylinder 60 is configured to embrace the reinforcing cheep 5 at both ends, and the stop ring 8 and the pack stop ring 8' are in contact with each other.

In FIG. 9, the stop ring 8 is used as a mere pressing plate, and the pack stop ring 8' acts as a wedge, and an O-ring as an elastic member is brought into contact with the end of the reinforcing chip 5.

The Q IJ song pack stop ring 8' is configured to be pushed between the inner inclined surface of the stop ring 8' and the outer surface of the internal cannulation tube 1.

Fig. 10 shows a configuration in which the pack stop ring 8' is formed of three rings and can change in the radial direction, and the inner intubation tube 1 is bent relative to the socket tube 2 despite the intervention of the pack stop ring 8'. It is now possible to do so. 41st
The figure is a front view of the pack stop ring 8' of FIG. 10.

In FIG. 12, unlike the embodiments A and B groups, the reinforcing chain 5 is in contact with the inner surface of the socket tube 2, and the elastic tube 6 is in contact with the inner tube 1.
The double cylinder shape is in contact with the outer peripheral surface of the
In this case, the elastic member 7 of the elastic tube 6 in contact with the inner tube 1 is
The pack stop ring 8' is wedge-shaped and pushed into the tapered inner surface of the pack stop ring 8' whose movement is prevented by the stop screw 13.

FIG. 13 shows an example in which a discharge tube corresponding to the internal tube 1 is connected to the discharge side of the jet pump.

This is convenient when replacing with a discharge pipe of a different diameter, or when replacement is required due to wear and tear. This jet pump guides the air flowing in from the air inlet 15 to the vicinity of the injection port of the high-pressure fluid injection nozzle 14 to eliminate the cavities that occur around the jet shoulder. The fluid sucked up from the 16 cylinders is lifted up or sent through the discharge pipe.

FIG. 14 shows a case where two internal intubation tubes 1 are inserted into a fixedly held socket tube 2 and connected to each other.

FIGS. 15 to 17 show the case where the double cylinder shape is integrally molded or bonded together with the canvas sheet 17. Particularly, FIG. A configuration in which the stop ring 8 and the pack stop ring 8' are sandwiched between two types of elastic cylinders 6 and 6' is shown, and Figure 17 shows an example in which the stop ring 8 and the pack stop ring 8' have a V-shaped cross section.

Although various embodiments have been illustrated and described above, it goes without saying that the invention is not limited to these and that many more embodiments can be created by partially combining each of them. In some drawings, the campus sheet is omitted, but whether or not the campus sheet is used in contact with the surface of the intubation tube is a matter of choice.

As described above, an elastic tube made of a material that does not stretch in the axial direction or a core material that does not stretch, and a reinforcing tube that is equipped with a fluid filling inlet and has an oval cross section are combined into a double barrel shape. Since the combination and the stop ring for imparting a wedge action to one or both ends of the elastic cylinder are attached directly or via an elastic member, a reliable connection can be achieved. In this state, pressurized air is sealed into the reinforcing tube from the fluid filling inlet, and the sealed pressure fixes the reinforcing tube and the elastic tube on the outer surface of the inner tube and the inner surface of the socket tube.

Internal pressure or external force in the direction of escape into the inner canal presses the elastic end or the interposed elastic member, which acts as a wedge to prevent it from coming off, and at the same time increases the internal pressure of the reinforcing tube due to compression, which pushes the inner tube toward the tube surface. It acts to increase the pressing force of. Therefore, it is flexible to some extent with respect to the axial force, and when a larger force is applied, Vc#-1 strongly resists. In addition, reinforced china is used for radial force.
The shape of the cross section of the tube or elastic cylinder is flexible. In this way, by simply processing the inner tube and socket tube to provide a hole or notch for exposing the fluid filling inlet, welding of 7 langes, threading, etc., can be performed on large diameter and long tubes. Processing for pipes has been eliminated and the number of piping parts has been reduced to 7.
We can provide the best piping seals in India for areas that are easily affected by transportation, heat retention, earth pressure, water pressure, waves, etc. without being stretched due to lunges, etc.
