The present invention relates to the material and properties of the sealing member 100. Since the sealing member 100 used in the present invention is inserted into the supply pipe to close the supply pipe 10, it is formed larger than the inner diameter of the supply pipe so as to be elastic. to close the inside of the supply pipe. Therefore, the sealing member 100 of the present invention uses a polyurethane or rubber or cork material having excellent elasticity.

The polyurethane is excellent in elasticity, abrasion resistance, processability, shock absorption, etc., and is used in various industries such as electrical insulators, structural materials, foam insulation materials, foam cushions, and elastic fibers, consumer goods, and parts. Therefore, it is important to select a product suitable for the application.

The polyurethane is broadly classified into thermoplastic polyurethane (T.P.U.) and thermosetting polyurethane (Thermoset Poly Urethane). Since the thermoplastic polyurethane is manufactured by melting with heat, extrusion, vacuum forming, thermal bonding, and high-frequency processing are possible, , By extrusion or injection method, there are no additional additives, and when heat is applied later, it can be melted and recycled. It has excellent elasticity with 650% elastic restoring force, and can be used in a wide temperature range of -40 degrees Celsius to 90 degrees Celsius. Oil resistance, It has excellent abrasion resistance and has the advantage of being a non-toxic and eco-friendly material. Both hard and soft foam materials are used as high foam materials, soft materials are used as elastic materials, and hard materials are used as insulation materials. Molding can mold various moldings at high speed by a molding method such as RIM (reaction injection molding). A porous product made of the polyurethane is polyurethane foam.

Therefore, since the sealing member 100 in the present invention is mainly inserted into the underground supply pipe and maintained for a long period of time, it is preferable to use thermoplastic polyurethane having excellent elasticity, non-toxicity, and capable of being maintained in a wide temperature range. do.

In addition, the sealing member 100 of the present invention includes one made of a rubber material.

In the present invention, the rubber material used as the sealing member 100 is preferably N.B.R (Nitrile-butadiene rubber; nitrile rubber). Nitrile rubber is a synthetic rubber made by copolymerization of acrylonitrile (ACN) and butadiene. Nitrile rubber or nitrile butadiene rubber (NBR) is a synthetic rubber made by synthetic polymerization of 2-propenenitrile and other butadiene monomers, and is a family of unsaturated polymers. It has high resistance to other chemicals, has a very high temperature resistance of -40 to 108 °C, can maintain elasticity, has excellent buffering and restoring power, and has excellent oil resistance, so it is used for fuel hoses, shoe soles, and automobile parts.

In addition, in the present invention, in order to smoothly insert the sealing member 100 into the supply pipe 10, the density of the front end 110 of the sealing member 100 is lower than the density of the distal end 120. . The density of the distal end 110 of the sealing member 100 is preferably made in the range of 60% to 95% of the density of the distal end 120 .

(Example 2-6) The present invention relates to a device for closing a fluid supply pipe. In Example 2-1, the sealing member 100 is formed in a cylindrical shape, and the outer diameter of the sealing member 100 is the supply pipe ( 10) to form a larger inner diameter; includes.

(Embodiment 2-8) The present invention relates to a device for closing a fluid supply pipe, and in Embodiment 2-1, the front end 110 of the sealing member 100 is protruded.

(Embodiment 2-9) The present invention relates to a fluid supply pipe closing device, and in Embodiments 2-8, the front end 110 of the sealing member 100 protrudes in a conical or trapezoidal shape; include

(Example 2-10) The present invention relates to a device for closing a fluid supply pipe. In Examples 2-6, the ratio of the outer diameter of the sealing member 100 to the inner diameter of the supply pipe 10 is 1.10 to 2.5; includes

The present invention relates to the shape of the sealing member 100, and specifically, the sealing member 100 is inserted into a certain position inside the supply pipe to block the movement of fluid. 2 shows the external shape of the sealing member 100 of the present invention. In general, since the inside of the supply pipe is made of a circle, the sealing member 100 of the present invention is also inserted into a certain position inside the supply pipe 10 to block the transfer of fluid, so the shape of the sealing member 100 is the supply pipe 10 ), it is formed in the shape of a cylinder filled with the inside, the same as the internal shape of To this end, the longitudinal direction of the sealing member 100 may be formed in a straight line to improve the blocking effect of fluid movement. In addition, in order to reduce friction, the longitudinal direction of the sealing member 100 is formed in a waveform to reduce the frictional area, so that the insertion of the sealing member 100 can be smoothly inserted.

When the shape in the longitudinal direction of the sealing member 100 is formed in a wave form, when the length (pitch) of the wave, the depth of the wave, and the bending radius of the wave are large, the sealing member 100 is bent at the part where the supply pipe such as the elbow pipe is bent. Since insertion is difficult and there is a concern that the sealing effect in the longitudinal direction of the sealing member 100 may deteriorate, the ratio of the length (pitch) of the wave to the outer diameter of the sealing member 100 is within 0.1, the depth of the wave is within 0.05, The bending radius of the waves should be formed within 0.03. On the other hand, as a result of conducting an experiment on a member having an outer diameter and length of 100 mm of the sealing member 100, the length of the wave is within 10 mm, the depth of the wave is within 5 mm, and the bending resistance of the wave is formed within 3 mm. It was confirmed that (100) was smoothly inserted into the desired position and had no effect on the sealing effect.

In addition, the present invention forms the front end 110 of the sealing member 100 to protrude in a conical shape, etc., so that the sealing member 100 can be smoothly guided in the flow direction of the supply pipe 10 in the process of being inserted into the supply pipe 10. let it be

Since the sealing member 100 of the present invention has elasticity, the outer diameter of the sealing member 100 is formed larger than the inner diameter of the supply pipe 10. Therefore, in the present invention, the outer diameter of the sealing member 100 is configured to be 1.05 to 3.0, preferably 1.08 to 2.7, and more preferably 1.10 to 2.5 compared to the inner diameter of the supply pipe 10. This is because when the outer diameter of the sealing member 100 is smaller than the inner diameter of the supply pipe 10, the supply pipe 10 is not sealed, making it difficult to block fluid transfer. Because it has to be pushed in with high pressure, there are cases where it is inserted further out of the inserted position. Therefore, the outer diameter of the sealing member 100 of the present invention is formed within the range of 1.10 to 2.5 than the inner diameter of the supply pipe 10 to be inserted.

In addition, since the external shape of the sealing member 100 in the longitudinal direction is inserted in contact with the inner diameter of the supply pipe 10, friction occurs during insertion, so a friction-reducing material capable of reducing friction in the longitudinal direction can be used. Since the friction-reducing material must be directly applied before the sealing member 100 is seated at the work site and inserted before it dries, when applied in the longitudinal direction of the sealing member 100 using a liquid coating agent, the supply pipe 10 is sealed with the inner diameter surface. Friction on the surface of the member 100 in the longitudinal direction can be reduced. To this end, lubricating oil or grease is applied to the longitudinal direction of the sealing member 100 . In the present invention, considering the ratio of the inner diameter of the supply pipe 10 to be inserted and the longitudinal direction of the sealing member 100, the viscosity of the lubricating oil is considered and used. If there is a large difference, the vertical force applied to the friction surface acts a lot, so a lubricant with high viscosity should be used. Therefore, the viscosity of the lubricating oil used in the present invention is 2.0 cSt or less.

The present invention relates to the external shape and length of the sealing member 100. Since the sealing member 100 in the present invention is installed to block the movement of fluid, the sealing member 100 has a front end 110 and a distal end. It is preferable to form the outer diameter of (120) the same. This is because the pressure of the fluid can be dispersed in the longitudinal direction of the sealing member 100 in the sealing effect. In addition, in order for the sealing member 100 to be inserted into a desired position, the outer diameter of the front end portion 100 of the sealing member 100 of the present invention is formed smaller than the outer diameter of the distal end portion 120 so that the sealing member 100 is inserted smoothly it is desirable At this time, when the outer diameter of the front end 110 of the sealing member 100 is rapidly reduced compared to the outer diameter of the distal end 120, the pressure of the fluid and the sealing effect are reduced, so the front end 110 of the sealing member 100 The outer diameter angle of is formed to be inclined in the range of 2 degrees to 15 degrees in consideration of the length of the sealing member (100).

Considering that the length (L) of the sealing member 100 of the present invention is formed in proportion to the total length (TL) of the supply pipe 10, the length (L) of the sealing member 100 of the present invention is the supply pipe 10 ) shall be formed with 1/10 to 1/20 of the total length (TL).

In addition, the length (L) of the sealing member 100 is formed larger than the outer diameter (D) of the sealing member 100 to increase the pressure and sealing effect of the fluid. At this time, the ratio of the length (L) to the outer diameter (D) of the sealing member 100 is formed to be 1.1 to 3.0. If the length (L) compared to the diameter (D) is too long, it is difficult to insert the sealing member 100, and if it is designed too short, there is a problem in that the fluid blocking effect is reduced.

Then, after combining the lower part of the sealing material input device 300 with the upper part of the granular tube 200 (S300), the sealing member 100 is seated on the seating part 310 formed on the inner lower part of the sealing material input device 300. let it do The sealing member seating step (S300) may include applying a friction-sensitive material to the outer diameter of the sealing member 100 in the longitudinal direction (S310). This is to reduce friction between the outer diameter of the sealing member 100 and the inner diameters of the granular pipe 20 and the supply pipe 10 so that the sealing member 100 is smoothly inserted.

In addition, when the sealing member 100 is seated in the sealing member input device 300, a fixing part coupling step (S320) of coupling the fixing part 210 of the distance adjusting member 200 to the sealing member 100 may be included. .

And it may include a ring part connection step (S330) to fix the ring part 230 of the distance adjusting member 200 to the ring support part 330 formed on the top of the sealing member inserting device 300.

After the sealing member 100 is stably seated in the sealing member input device 300, the connection port 440 of the compressed fluid supply device 400 is connected and installed on the top of the sealing member input device 300 to insert the sealing member. The device 300 and the pressure fluid supply device 400 are connected and coupled (S400).

In the present invention, when the compressed fluid supply device 400 is coupled to the sealing member input device 300, the installation of the fluid supply pipe closing device is completed.

In the next step, the riser valve installed on the upper part of the riser tube 20 is opened so that the sealing member 100 can be inserted into the riser tube 20 and the supply tube 10. Then, the pressure vessel opening/closing valve 440 of the pressure fluid supply device 400 is opened to supply the pressure fluid so that the sealing member 100 passes through the granular pipe 20 and reaches the supply pipe 10 .

At this time, due to the sealing member 100 seated at the bottom of the sealing member input device 300, when pressure is applied through the compressed fluid supply device 400 in a state in which the upper portion of the granular pipe 20 remains sealed, the sealing member (100) passes through the granular pipe 20 and is inserted into the underground supply pipe 10 (S600). At this time, the appropriate pressure of the compressed fluid supplied from the compressed fluid supply device 400 is supplied within the range of 1.5 to 7 kg/cm2 as described above, but it is preferable to supply the appropriate pressure at 2.5 to 4.0 kg/cm2. .

In the present invention, after the supply pipe insertion step (S600) of the sealing member 100, the compressed fluid supply device 400 is removed to check whether the sealing member 100 is inserted into the desired position of the supply pipe 20 (S700) It may include a sealing member insertion position confirmation step (S710) of confirming the insertion position of the sealing member by doing.

At this time, when the sealing member 100 is inserted more than the normal position, the distance adjusting unit 220 is adjusted to move the sealing member 100 to the normal position, or if the sealing member 100 is inserted less than the normal position, After reinstalling the compressed fluid supply device 400, it may include a sealing member insertion position adjusting step (S720) to additionally insert the sealing member 100 by receiving additional pressure from the compressed fluid supply device 400.

At this time, if the sealing member 100 is inserted less than the original position and additional pressure is required, it causes inconvenience that additional work procedures such as reinstallation of the device must be performed. This problem can be solved by supplying from 20% to 20%.

And when the sealing member 100 is inserted more than the normal position, pull the distance adjusting unit 220 and adjust it so that it can come to the correct position.

In addition, the present invention may include a step of sealing the cap of the granular pipe (S810) by sealing the upper end portion of the granular pipe with a cap to prevent rainwater and foreign matter from entering after removing the sealing member inserting device 300 (S800).

After the sealing member 100 is inserted into the supply pipe 10 at a normal position through the fluid supply pipe closing device of the present invention, the fluid supply pipe is closed, so the work is completed and the equipment is withdrawn (S900).

Therefore, the method of closing the supply pipe using the fluid supply pipe closing device of the present invention can significantly shorten the construction period by effectively blocking the fluid transfer through simple equipment without underground excavation of the supply pipe buried in the basement outside of the building or house. It also has the effect of reducing construction costs.
