Description

{Blocking Device of Pipe Leak}

The present invention relates to an apparatus and a method for temporarily blocking fluid leakage in a pipe.

BACKGROUND OF THE INVENTION [0002] The art of the present invention is a method for preventing leakage of a pipe in a state where leakage is occurring. Normally, the leakage part is wrapped and tightly tightened to stop the fluid leaking out.

As a background of the present invention, Korean Patent Registration No. 10-0453450 (Oct. 10, 2004) entitled " Systematic Seal Sealing Device Leaked in Pipes " discloses a system for sealing a leakage portion of a pipe, allowing a leakage fluid to flow through a pipe temporarily installed, A device for locking the valve to prevent leakage is provided. Korean Patent Registration No. 10-0692102 (Mar. 3, 2007) "Gas Leakage Cutoff Device for Gas Pipeline" discloses a method and apparatus for preventing gas leakage through a flange.

Korea Patent Registration No. 10-0453450 (Oct. 10, 2004) "Systematic Sealing System Leaked from Pipes" has a device for temporarily blocking the leakage of the pipe by flowing the leaked fluid through the piping which temporarily surrounds the leaked portion of the pipe, The technique of installing the valve packing is applied to the pipe. In the actual situation, when the high pressure fluid flows out, the surface of the pipe is not as smooth as the stem of the valve, resulting in secondary leakage through the pipe surface. This results in an impossibility of blocking the leakage. In order to prevent this, it is necessary to use a long packing, and the device becomes very troublesome.

The present invention is to prevent such secondary leakage, and when it is difficult to seal the leakage fluid through the packing, the secondary leakage fluid flowing through the secondary leakage fluid is collected by a separate pipe to manage the leakage of the pipe temporarily .

If it is difficult to completely seal the leakage generated in the pipe flowing the high-pressure fluid through the present invention, it is possible to manage the leakage fluid in the pipe system without releasing the leakage fluid to the atmosphere, thereby reducing the risk of leakage of the piping system And improved stability.

As shown in FIG. 1, the present invention includes a leakage fluid regulating device that surrounds a leakage portion of a pipe having a leakage portion in a pipe and provides a separate small pipe to stop the leakage through the valve while guiding the leaked fluid, The fluid regulating device is divided into a gap fluid regulating device which again surrounds the vapor leaking between the leakage fluid regulator and the pipe and installs a separate small pipe to stop the leakage through the valve while guiding the leaked fluid. The present invention relates to a device and a method for temporarily blocking fluid leakage in a piping that encloses a fluid and a pipe and ultimately blocks the leakage of the pipe or minimizes the amount of leakage fluid and guides the same to a certain pipe will be.

Therefore, the present invention consists of one leakage fluid regulating device and two gap fluid regulating devices which surround the pipe including the leakage part. The leakage fluid regulating device is composed of a fluid leakage chamber and a leakage fluid guide pipe. The fluid leakage chamber is a space between the upper and lower lids having the upper and lower inner plates, that is, a space between the upper and lower bodies and the upper and lower inner plates. The gap fluid regulating device is composed of a gap interrupting device in a small space formed between the pipe and the upper and lower body of the fluid leakage chamber at the upper and lower inner plates, a gap fluid delivery device, a gap leakage chamber, and a gap fluid guide pipe. The gap sealing device is composed of a packing and a packing pusher. The gap fluid delivery device is composed of a leakage derivative and upper and lower packing guides. The gap leakage chamber is a space of both ends of the upper and lower bodies and upper and lower packing guides. Make a hole by connecting the pipe and the valve. In the present invention, the term " upper and lower portions " refers to a state in which upper and lower members are assembled to form a complete donut shape, and the upper and lower inner plates refer to a state in which the upper inner plate and the lower inner plate are assembled. The upper and lower portions to be described later are all used in this manner.

To this end, the present invention relates to a pipe leakage preventing device characterized by comprising a leakage fluid regulating device and a clearance fluid device as shown in FIG. The leakage fluid regulator is a device for preventing the leakage of fluid by blocking the valve installed in the temporary pipe so that the fluid leaking out of the pipe flows into the atmosphere or flows out of the pipe to the temporary pipe, The regulator is a device that prevents the fluid leaking to the outside of the pipe temporarily installed in the leakage fluid regulator by controlling the flow direction of the fluid by installing a temporary pipe to prevent the fluid leaking out to the atmosphere .

As shown in FIG. 2, the leakage fluid regulating device includes a fluid leakage chamber 110 that surrounds the leakage portion of the pipe 10 having the leakage portion 20 formed therein, a leakage fluid guide pipe (130) for enclosing a fluid leaking from a gap between the pipe and the leakage chamber, a gap fluid guide pipe (140) connecting the pipe and the valve to the gap leakage chamber A clearance blocking device 150 for blocking a gap between the pipe and the leakage chamber, and a clearance fluid delivery device 160 for guiding clearance fluid leaking through the clearance blocking device.

The pipe 10 is also referred to as a tube or a hose as a high-pressure or vacuum pipe used in a process used for industrial purposes. Pipes and piping are generally referred to as pipelines, which are the same in the present invention, and pipes that are leaked in the present invention. The leakage part 20 is a place where a fluid is leaked due to a defect such as a pin hole or a crack in the pressurized pipe, or the fluid is sucked in because the inside is evacuated. The fluid leakage chamber 110 surrounding the leakage portion of the pipe 10 is wrapped around the leakage portion of the pipe in order to collect or manage the leaked fluid in one place without being ejected into the atmosphere It is the room that I put. A leaked fluid guide pipe (120) connecting a pipe to a valve in the fluid leakage chamber forms a nozzle in a normal pressure vessel to allow the pipe to branch off from the pressure vessel. A valve is attached to the pipe to leak the fluid It is a pipe that guides the flow path of the fluid to collect. Here, the pressure vessel becomes a fluid leakage chamber. The leakage fluid regulating device corresponds to the gap fluid regulating device in which the fluid leaked from the device according to the present invention leaks back to a part of the device according to the present invention in the sense of directly regulating the leaked fluid. The fluid leaking from the gap between the pipe and the leakage chamber will be described in detail as follows. If the fluid leakage chamber is wrapped around the leakage of the original pipe, all the leaked fluid must be collected in this fluid leakage chamber. However, it is difficult to completely cover the high-pressure fluid through the O-ring or the seal by mechanically sealing the pipe leakage portion unless the casing materials constituting the fluid leakage chamber are joined to the pipe by welding or the like. This is because the outer surface of the pipe is uneven and the industrial pipe itself is not a source. Therefore, it is difficult to completely seal the gap between the pipe and the fluid leakage chamber through mechanical assembly in the apparatus of the present invention, which is installed urgently in order to prevent the leaked steam of the leakage portion formed in the pipe in the case of high-pressure fluid, We want to control the leaked fluid to collect the fluid back into the process system without releasing it to the atmosphere. Therefore, the clearance leakage chamber 130, which surrounds the fluid leaking from the gap between the pipe and the fluid leakage chamber, is designed to once again surround the fluid leaking from the fluid leakage chamber toward the pipe. The clearance fluid guide pipe 140 connecting the pipe and the valve to the clearance leakage chamber has the same structure as the above-described leaky fluid guide pipe but is different in that the nozzle is connected to the clearance leakage chamber 130. Since the leakage fluid guide pipe must have an inner diameter to allow the entire amount of the leakage fluid to flow, the diameter of the gap fluid guide pipe must be made smaller than that of the leakage fluid guide pipe because a fluid leaking into the gap needs to be flowed Economical and desirable. The gap separator 150 for blocking the gap between the pipe and the leakage chamber sees the pipe as a stem of the valve and seals the fluid leakage chamber in the casing of the valve to prevent leakage through the handle of the valve. And the same structure as that of the stem sealing packing of Fig. This can be done with the same structure as the packing provided between the shaft of the pump and the casing. However, in the present invention, in using a plurality of packings, a leakage derivative is provided between the packings to force the leakage fluid to the atmosphere in the middle. The clearance fluid delivery device 160 for guiding the gap fluid leaked through the clearance blocking device includes the upper inner plate 42 and the lower inner plate 32 and the outer surface of the pipe 10 and the upper packing guide 43 The fluid leaking through the packing in the space surrounded by the lower packing guide 33 and the outer shell 70, that is, the space between the pipe and the upper and lower bodies, passes through the packing guide, passes through the packing hose It is the Euro to flow. If the space between the packing guide and the pipe is filled with only the packing 50 without the leakage derivative 60, it can be used as a bonnet, a stem, a packing, a gland flange ) Or gland ring, and a member that presses a packing called a gland cover. However, according to the present invention, a leaky fluid 60 is provided between a plurality of packings, and a flow path is formed in the upper packing guide 43 and the lower packing guide 33 at positions where the leaky derivatives are present, Which can flow between the upper inner plate and the outer sheath, is different from the packing and structure of the conventional valve. The leakage derivative 60 has a structure similar in shape and size to a packing, a structure in which a fluid can flow through the member by using a material such as a plurality of holes formed in a mesh or a cylinder.

As shown in FIG. 1, the leakage fluid regulating device is constructed so that a pipe is formed so as to surround a pipe including a leaked leakage portion, and a pipe and a valve are connected to the pipe so that a leaked fluid flows through the pipe It is a device that adjusts the direction of a fluid flow. As shown in Fig. 7, the upper and lower lids are divided into upper and lower lids, respectively, so that the upper lid can be covered on the pipe in the field, and a leakage hose is connected to the upper lid. Therefore, the leakage fluid regulating device includes a lower cover 30 having a lower inner plate 32, an upper lid 40 having an upper inner plate 42, a leakage hose 80 And can be implemented by anyone referring to the embodiment illustrated in FIG.

3, 4, and 5, the lower cover 30 is provided below the leakage portion, and has a connecting means provided at an edge of the pipe dividing the pipe larger than the outer diameter of the pipe. In the radial direction of the leakage portion, . The lower inner plate 32 is a part of the lower cover 30 and constitutes a wall blocking the axial direction of the leakage portion. The upper lid 40 is disposed on the upper portion of the leakage portion, and has a connecting means at its edge by a barrel larger than the outer diameter of the pipe, and constitutes an outer wall body in a radial direction of the leakage portion. The upper inner plate 42 is in the upper lid 40 and constitutes a wall blocking the axial direction of the leakage portion. The leakage hose (80) opens a hole at an intermediate position of the upper cover to connect the pipe.

The lower cover 30 is composed of a lower body 31 and a lower inner plate 32 as shown in FIG. The lower body 31 is a tube surrounding the pipe, and the plate that covers the space between the through pipes at both ends of the pipe is a lower inner plate. Since the tube must be wrapped around the pipe at the leak site, it should be cut in half, so it is the lower body that is placed under the half of the cut, and the upper body is the one that is placed on the upper body. When the lower body is formed into a cylindrical shape, the lower body can be made by cutting the cross section of the cylinder in half. As shown in FIG. 3, the lower lid 30 is a device for wrapping the leaked portion of the pipe and flowing the leaked fluid to a separate pipe. The lower lid 30 is disposed below the leakage portion as viewed in the cross-sectional direction of the pipe, And an outer wall body in the radial direction of the leakage portion. Providing the connection means at the edge means integrating all the parts where the lower body and the upper body meet to form a closed structure. When this connection is made, the upper body and the lower body become one complete cylinder, and the lower inner plate and the upper inner plate connected to the body are also integrated so that the upper cover and the lower cover constitute one cylinder. Since the lower body should be any tubular structural member, it must be integrated with the upper body to be integrated with the structure of the airtight cylinder, so that there is no leakage of fluid through the fastening device to be fastened to the upper body, Equipment. Generally, the fastening device can be a flange, a bolt, and a nut, and a gasket or an O ring can be used as an airtight device. Fig. 5 shows a lower flange 34 having a flange shape by perforating a conventional flat plate as an edge connecting means. As the fastening device, a lower connection hole (35) having a hole in the plate was adopted. When the bolts and nuts are fastened to the lower connector through the upper connector, a fluid leakage chamber 110 is provided. At this time, it is common knowledge of a mechanical engineer that it is not necessary to insert a gasket or an O-ring between the upper flange and the lower flange and use a fastening device. In addition to the embodiment of FIG. 5 of the present invention, the upper body and the lower body can be variously integrated by a method of fastening the upper body and the lower body to each other by using bands, or by using quick coupling means.

The lower inner plate 32 is a donut-shaped plate whose inner diameter is larger than the outer diameter of the pipe and whose outer diameter coincides with the inner diameter of the lower body and the cylinder formed by the upper body. Since the donut-shaped plate is to be assembled so as to surround the pipe, one of the C-shaped plates cut in the middle is the lower inner plate and the other is the upper inner plate. Therefore, the lower inner plate constitutes a wall which is in the lower cover 30 and blocks the axial direction of the leakage portion. 3, the lower inner plate constitutes a wall enclosing the space between the lower body and the pipe in the axial direction of the pipe in the leakage portion, while being in the lower body 31, as illustrated in Fig. As a result of this wall, the leaked steam moves only in the direction of the leakage hose, and does not flow in the pipe axis direction. Although Fig. 6 shows one embodiment of the outer sheathing 70, the lower inner sheath or the upper inner sheath is similar in appearance to that of the outer sheath 70, except that they are of different sizes and different fastening devices. The outer circumference of the circle which makes the lower inner plate and the upper inner plate become the donuts is integrated by a method such as welding with the inner circumference of the lower body.

The upper lid 40 is constituted by an upper body 41 and an upper inner plate 42 as illustrated in Figs. As shown in Fig. 3, the upper lid is connected to a leakage hose 80 for flowing a leakage fluid, while being connected to a pipe for enclosing the pipe. The upper lid 40 is disposed at an upper portion of the leakage portion, and has a connecting means at its edge by a barrel larger than the outer diameter of the pipe, and forms an outer wall body in the radial direction of the leakage portion. The upper inner plate 42 is in the upper lid 40 and constitutes a wall blocking the axial direction of the leakage portion. The leakage hose (80) opens a hole at an intermediate position of the upper cover to connect the pipe. The entire structure of the upper cover is the same as the lower cover 30. Fig. 5 is an embodiment of the lower lid, except that the upper lid has the same structure and has a further leakage hose in the middle. Therefore, the structure of the upper cover can be determined by changing all the numbers shown in FIG. 5 from 30 to 40, and changing the designation from "lower" to "upper". In other words, as shown in FIG. 7, the bottom of the barrel is placed on top of the top cover, and the half of the barrel is placed under the bottom cover, except that there is only a leakage hose. Therefore, in the embodiment of the present invention, the constituent members of the upper lid are enumerated one by one and the description thereof is omitted.

As described above, the gap fluid regulating device is configured such that the fluid through the primary leakage leaking through the leakage portion of the pipe other than the pipe temporarily installed in the leakage fluid regulating device is discharged to the atmosphere through the gap between the fluid leakage chamber and the pipe A temporary flow path is formed so as not to cause leakage so as to control the flow direction of the fluid through the secondary leakage and ultimately to block the flow of the secondary fluid. Here, in order to prevent the secondary leakage fluid leaking to the outside of the pipe temporarily installed in the leakage fluid regulator from being discharged to the atmosphere, a small space is formed between the pipe and the lower body body, And the upper and lower inner plates are occupied by the packing so that the packing blocks the fluid leaking through the gap between the pipe and the upper and lower inner plates so that the fluid leaking out of the pipe ultimately flows through the gap between the pipe and the fluid leakage chamber This is to prevent the leakage of the fluid to the atmosphere, that is, the secondary leakage. Normally at low pressures this packing will be sufficient to prevent this secondary leakage, but if the pressure is high, this leakage can not be prevented. In the present invention, the fluid through the secondary leakage is called a gap fluid, and a device for forming a flow path by a pipe in which the gap fluid is temporarily installed is called a gap fluid regulator.

Therefore, a small space formed between the pipe and the upper and lower body cylinders serves as a space for storing the slit stopper 150, and can be explained with reference to the drawings formed on both ends of the pipe in Figs. 3 and 4. The small space formed between the pipe illustrated in Figs. 3 and 4 and the cylinder of the lower body is a space formed by the outer peripheral surface of the pipe, the outer plate surface of the upper and lower inner plates, the pipe direction surface of the upper and lower packing guides, and the upper and lower inner plate surfaces of the outer plate. This is the same configuration as the leakage preventing mechanism in the handle direction of the valve when the pipe is referred to as the stem of the valve. However, the leakage derivatives and upper and lower packing guides are different. Therefore, the gap fluid regulating device according to the present invention is characterized in that a gap and a leakage derivative are closely packed between a small space formed between a pipe and a lower body and a space between the pipe and the small space, and a fluid leaking through the packing, When the fluid is present, it is a device that does not discharge it to the atmosphere but forms a flow path so that it can go to a separate auxiliary hose.

The gap fluid regulating device consists of packing, leakage derivative, upper and lower packing guide, shell, packing pusher and auxiliary hose. The packing 50 uses ordinary packing to block the fluid leaking between the pipe and the upper inner plate 42 and the lower inner plate 32. The leakage inductors 60 are positioned between the packings to form a flow path through which the leaked fluid meets the atmosphere. The leakage derivative 60 has a structure such that the fluid can flow through the member using a material similar to the shape and size of the packing as described above, or a plurality of holes formed in a net or a cylinder. The upper and lower packing guides are composed of an upper packing guide 43 and a lower packing guide 33 mechanically guiding the packing and the leakage derivative. The outer plate 70 is formed by dividing the donut-shaped plate to form the outer plate body 71 and the outer plate fastening holes 73 (see FIG. 6) which are fastened to the outer plate fastening holes 37 of the upper and lower bodies, ), And they are combined with a normal fastening mechanism. The outer plate fastening port is threaded, the outer plate fastening hole is only a hole, and the central axes of the two holes are aligned with each other so that the outer plate can be easily connected to the upper and lower bodies by fastening them with bolts. At this time, when the upper and lower shell bodies are attached to each other to form a donut shape, the surfaces to be adhered to each other should be such as a sealing device, a gasket or an O-ring. In this way, when the shell plate is coupled to the upper and lower bodies, the packing and the upper packing guide 43 and the lower packing guide 33 are enclosed. The upper and lower packing guides 33 and 43 are formed by forming a plurality of holes in a pipe having an inner diameter larger than that of the pipe and having a smaller outer diameter than the upper and lower bodies to form a flow path through which fluid can flow, As shown in FIG. 5, the upper and lower packing guides are fastened to the packing guide tightening members provided on the upper and lower inner plates so that the upper and lower packing guides are integrated with the upper and lower inner plates. A plurality of apertures drilled therein serves as the gap fluid delivery device 160. This is because the fluid leaked through the packing passes through the space of the leakage inductor 60 and passes through a large number of holes in the upper and lower packing guides, which passes through the gap leakage chamber and exits the auxiliary hose. The upper and lower packing guides can be used to tighten the packing by using a plurality of perforated bands or by screwing the bolts perpendicularly to the upper and lower bodies so that the bolts reach the upper and lower packing guides. The upper and lower packing guides and the upper and lower inner plates may be manufactured by welding. Alternatively, the upper and lower packing guides may be manufactured by turning, such as a lathe, a milling, or the like. In another embodiment, the outer plate and the upper and lower packing guides may be fastened from the outer plate to the packing guide tightening hole by using long bolts by taking out a hole that coincides with the center of the packing guide tightening hole of the upper and lower inner plates. The packing pusher 52 presses the packing and the leaked derivative in a small space formed between the pipe and the lower body body, thereby joining the plate to the outer plate with the size of the pipe entering the space between the upper and lower packing guides, When the outer plate fastener is fastened, the packing and the leakage conductor may be pressed to seal the packing, or the external plate may be provided with a separate press-fitting device to press the packing and the leakage conductor. The packing pusher may be used as a packing pusher by using a bolt fitted to the outer plate, such as a large star point, which is not a small point of the outside sheath shown in Fig. Fig. 6 (1) is a front view of the outer sheath, and Fig. 6 (2) is a sheath diagram of the outer sheath. The auxiliary hose 90 can be used by attaching a pipe to the pipe by making a hole in the upper lid that is outside the packing and the upper inner plate, and attaching a valve to the pipe. The fluid leaking between the pipe and the upper inner plate 42 and the lower inner plate 32 is the above-mentioned secondary leakage fluid or gap fluid. The packing uses packing which prevents the leakage of the stem of the normal valve or packing which prevents leakage between the axis of the pump and the casing. The packing can be prevented from leaking by arranging the packing in a zigzag direction so that the cut portions of the packing do not meet the upper and lower joints, which is the same as the procedure for installing the valve packing.
