Description

[0001] The present invention relates to a leakage prevention apparatus of a pipe,

The present invention relates to an apparatus for preventing leakage of a piping connection part, and more particularly to a piping connection part leakage prevention device installed to prevent leakage of two piping connection parts for connection.

Generally, a pipe used as a passage of a fluid is connected to a plurality of pipes so as to secure a sufficiently long pipe length. In the case of onshore plants, piping can be fixedly connected in the same way as welding. However, on ships, structural deformation such as hogging and sagging due to external waves occur repeatedly, and there is a risk that the pipe will be destroyed if the deformation exceeds a certain size. Therefore, the connection of two pipes is not fixed in the form of welding so that the piping is not damaged by structural damage even if a certain size is deformed. At this time, a connection is formed to surround the connection of the two pipes, and a packing is inserted between the connection and the two pipes inside.

However, there is a problem that the fluid leaks from the pipe connection portion where the connection is installed. It is presumed that when the cause can not be precisely determined, the packing is worn by repetitive thermal expansion, or the packing of the connection is damaged due to repetitive hogging and sagging, resulting in fluid leakage. Therefore, it is urgently required to develop a technique for preventing leakage of fluid from the piping connection portion.

In order to prevent the leakage of fluid between the fixed pipe and the piping, the fixed pipe is provided with a fixing pipe which is fixed to the inside of the pipe to prevent the fluid from leaking between the pipe and the pipe. A supporting ring having an inner inclined surface formed on one side thereof and a fixing ring for fixing the end of the supporting ring to the inner side of the inclined surface of the supporting ring, And a pressing member which is mounted on the inner circumferential surface of the body of the tube and firmly presses the outer circumferential surface of the tubular member coupled to the inside of the cylindrical body, And a fastening member for forcibly fixing the fastening hole of the pressure member to the fastening hole of the pressure member, It improves the productivity by increasing the productivity by shortening the joining process and the working time due to the simplification of the auxiliary structure and improving the economical efficiency by reducing the manufacturing cost and firmly joining the both ends of the piping material inside the fixed pipes. A synthetic resin piping material connecting device capable of using semiconductors in a stable manner while improving the reliability of a product has been proposed (refer to Patent Document 1).

The present invention also provides a method of manufacturing a female pipe having a female pipe having an expanded portion having an inner diameter expanded at an end thereof, a water pipe inserted and connected to the expanded portion of the female pipe, And the watertightness between the water pipe and the water pipe is maintained, so that the both pipes can be mutually connected by male and female structures and the watertightness of the water pipe can be maintained. As a result, There has been proposed a piping connection structure and a connection method which can simplify piping connection work and provide an excellent watertightness maintenance function (refer to Patent Document 2).

In order to meet the above-mentioned need, the present invention is directed to a method for sealing a piping connection portion which can effectively prevent fluid leakage in a piping connection portion by strongly urging a sealing member against a piping connection portion by using a fluid flow in a region where a conventional piping connector is located The present invention has been made to solve the above problems.

According to an aspect of the present invention, there is provided an apparatus for preventing leakage of a piping connection portion, the apparatus comprising: A receiving portion provided so as to be able to be moved; A leg portion connected to the receiving portion; And an internal resistor connected to a distal end of the leg portion and having a body portion in which a resistance is generated by the flow of the fluid.

Here, the receiving portion may be realized by providing a plurality of cantilevered supports.

Further, the receiving portion, the leg portion, and the internal resistor may be hinged to each other.

In addition, a plurality of the leg portions may be provided along the receiving portion.

Further, the internal resistor may be cylindrical.

Also, the internal resistor may have a propeller on the outside.

According to the present invention, the sealing member is strongly adhered to the piping connection portion by using the fluid flow inside the piping, thereby effectively preventing the fluid leakage from the piping connection portion.

1 is a conceptual view of an apparatus for preventing leakage of a piping connection portion according to the present invention.
2 is a conceptual view of an internal resistor according to the present invention.
3 is a view showing a state of use of the piping connection portion leakage preventing device according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 1 is a conceptual view of an apparatus for preventing leakage of a pipe connection according to the present invention, FIG. 2 is a conceptual view of an internal resistor according to the present invention, and FIG. 3 is a state of use of the apparatus for preventing leakage of a pipe connection.

According to the present invention, there is provided an apparatus for preventing leakage of a piping connection part, wherein the sealing member is strongly adhered to a piping connection part by using a fluid flow in a section where a conventional piping connector is located, thereby effectively preventing fluid leakage from the piping connection part. .

As shown in the drawing, the piping connection portion leakage preventing device 100 according to the present invention is installed in a connecting portion of two pipes 10 and 20 for connection to prevent leakage, and includes a receiving portion 110, A leg 120, and an internal resistor 130.

The receiving portion 110 is installed inside the end portion of the pipe 10 or 20 so that the sealing member P can be received along the circumferential direction.

At this time, the receiving portion 110 is not particularly limited, but a plurality of cantilever-type supports may be provided. The cantilever-type support base serves as a fixing step for preventing the sealing member P from escaping to the outside.

The leg portion 120 is connected to the receiving portion 110 in a direction of flow, and has a predetermined length. At this time, a plurality of the leg portions 120 may be installed along the receiving portion 110 at regular intervals.

The internal resistor 130 is connected to the tip of the leg 120, and has a body to generate resistance by the flow of the fluid. At this time, it is preferable that the internal resistor 130 is cylindrical in consideration of the internal flow.

In addition, the internal resistor 130 may further include a propeller 132 on the outside in case the fluid does not flow. Accordingly, when the fluid does not flow, the propeller 132 is forcibly rotated to generate the propeller thrust so that the leg portion 120 can be pushed out.

Meanwhile, the receiving portion 110, the leg portion 120, and the internal resistor 130 may be hinged so that they can freely move between each other.

Hereinafter, the operation of the piping connection portion leakage preventing device 100 according to the present invention will be described.

First, when there is a fluid flow, a resistance is generated and the internal resistor 130 is pushed out.

Then, the leg 120 is pushed toward the receptacle 110 by the internal resistor 130, and the leg 120 pushes the receptacle 110.

Lastly, the receptacle 110 is pushed so that the sealing member P is firmly brought into close contact with the connecting portion of the pipes 10 and 20, thereby effectively preventing the leakage of the fluid from the connecting portions of the pipes 10 and 20. [

For reference, the piping connector leakage preventing device according to the present invention can be used in parallel with a conventional connector, but can be used alone if necessary.
