Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a connection structure for piping of a ship which provides a connection mediation function so that the piping installed at the boundary between the assembly block structures can be connected to each other when the assembly block structures independently manufactured in the course of drying the ship are connected to each other A connection structure of a new structure type in which both of the advantages of a socket type connection structure in which a step is formed and the advantages of a sleeve type connection structure in which a step is absent can be exerted. It is possible to solve both the difficulty in assembling the connection structure and the insufficient stability and robustness of the connection of the sleeve type connection structure.

Generally, several assembly block structures which are independently manufactured in the course of drying the ship are assembled for connection in a subsequent process. At this time, assembly connections are also established between the pipelines located at the boundary between the building block structures, and a piping connection structure (hereinafter referred to as a connection structure) of the ship is used as a connection medium for assembling and connecting the pipelines.

1 and 2, the connection structure 10 described above is divided into a socket-type connection structure 12 and a sleeve-type connection structure 14. As shown in FIG.

Since the socket-type connection structure 12 has the stepped portion 20 formed at the intermediate portion thereof with the inner diameter thereof narrowed, the inner diameter of the pipe 18 remains the same as that of the pipe 18, It is possible to insert and fasten the pipe 18 with an accurate length. Further, since the step 20 prevents the pipe 18 from being pushed in the direction in which the pipe 18 is inserted, safety and rigidity can be secured.

However, in the case where, for example, one side pipe 18 is to be further pushed into the socket-type connection structure 12 due to an assembly error between the assembly block structures, the socket- There is a disadvantage in that it is difficult to insert the pipe 20 beyond the step 20 due to the step 20, which is a disadvantage that it can not be used in response to an assembly error.

When the sleeve type connection structure 14 is used to solve the disadvantages of the socket type connection structure 12 as described above, the sleeve type connection structure 14 can be formed in a shape different from the socket type connection structure 12, It is possible to insert the pipe 18 in a state in which the pipe 18 is further pushed in because the pipe 20 is not formed so that the drawback of the socket type connection structure 12 can be solved, There is a disadvantage in that it is not structurally provided with a step function for preventing the insertion of the piping 20 beyond that, so that it is not possible to secure the fixing force for the coupling as well as the assembly position.

Accordingly, the present invention proposes a new structure type connection structure for ship piping to solve all the disadvantages of the socket connection structure 12 and the sleeve connection structure 14 described above.

The present invention relates to a new structure type connection structure capable of exerting both the advantages of a socket type connection structure in which a step is formed and the advantages of a sleeve type connection structure in which a step is not formed, The connection structure for piping of a ship which can solve both the difficulty in assembling the socket-type connection structure and the insufficient stability and the robustness of the connection of the sleeve-type connection structure by the connection structure thus presented The purpose is to provide.

A body formed to include a connection portion formed on both sides with a length so as to be coupled in a form in which the pipe is inserted, and an expansion portion having an inner diameter expanded between the connection portions; A pressing member which is received in the bending portion of the body and is formed in a hollow structure; A cut-out portion that is cut in the longitudinal direction of the pressing member so that the inner diameter of the pressing member can be variably adjusted; The present invention can achieve the object through the connection structure for piping of the ship including the water piping.

In addition, both ends of the pressing member on which the pipe is brought into contact can achieve the object through the connecting structure for piping of the ship, which is formed as an inclined surface so that the pressing member can spread in the radial direction.

In addition, an object of the present invention can be achieved through a connection structure for piping of a ship in which an inner diameter of a piercing member in which a cut-out portion is tightened so that the pipe can come into contact with an inclined surface of the piercing member is less than an inner diameter of the connection portion.

The object of the present invention can be attained through a connection structure for piping of a ship in which a pressure-tightening force due to the spreading of the pressing member and a sealing member for preventing foreign matter from being caught are filled between the pressing member and the pipe-

If the piping connection structure according to the present invention is used, both the advantages of the socket-type connection structure and the advantages of the sleeve-type connection structure without the step are exerted, and the difficulty in assembling the socket- It is possible to expect the effect of solving both the safety of the bonding of the structure and the insufficient stability.

In addition, when the connecting structure for piping of the ship according to the present invention is used, the socket type connecting structure and the sleeve type connecting structure are unified so that productivity as well as workability can be expected together.

Hereinafter, a preferred embodiment of a connecting structure for piping of a ship according to the present invention will be described in detail.

As shown in FIGS. 3 and 4B, the connecting structure for piping (hereinafter referred to as " connecting structure ") of the ship according to the present invention includes a body 32 formed of a hollow structure, And a hermetic holding member 36 provided in a form filled between the pressing member 34 and the body 32 to provide foreign matter prevention and resilient force.

Specifically, the body 32 includes a connecting portion 38 extending on both sides so that the pipe 18 can be inserted therein, and a connecting portion 38 formed between the connecting portion 38 and the connecting portion 38 And an expanding portion (40).

The piercing member 34 is formed in a hollow structure and the piercing member 34 is cut from one end to the other end of the piercing member 34. [ A cut portion 42 is formed. The cut portion 42 is preferably formed in a slanting line.

The inside diameter d1 of the pressing member 34 is set so that the inside diameter d1 of the pressing member 34 is in contact with the inclined surface 44 while the pipe 18 is in contact with the inclined surface 44 The inner diameter d2 of the connecting portion 38 is smaller than the inner diameter d2.

As described above, since the pressing force due to the spreading of the pressing member 34 is strengthened, the gap between the pressing member 34 and the bending portion 40 is reduced, The airtightness maintaining member 36 is filled in order to prevent deformation of the airtightness. The airtightness maintaining member 36 is provided so as to entirely surround the outer periphery of the pressure sensing member 34.

FIG. 3 is a cross-sectional view illustrating a connection structure for piping of a ship according to the present invention, in which a pipe is coupled to a socket-type pipe.

The pipe 18 is inserted into the connection portion 38 of the body 32 when the pipe 18 is installed and connected. At this time, the pipe 18 inserted into the connection portion 38 is tightly engaged with the inclined surface 44 of the binding member 34. That is, since the inner diameter d1 of the pressing member 34 is formed to be smaller than the inner diameter d2 of the connecting portion 38 as described above, the advantages of the socket type connecting structure described in the background art can be provided do.

On the other hand, for example, when the piping 18 disposed on both sides is fixed in position and the piping 18 is further pushed in due to the occurrence of an error, as shown in FIGS. 3 to 5, When the connecting structure 30 is moved in the direction in which the pipe 18 is further inserted in a state in which the pressing member 18 is in close contact with the inclined surface 44 of the pressing member 34, As shown in FIG.

At this time, the inclined surface 44 is formed so that the pressing member 34 is pushed in the radial direction, so that the pipe 18 enters the inside of the pressing member 34 while riding the inclined surface 44. The cut portion 42 opened at the same time is opened so that the inner diameter d1 of the pressing member 32 becomes large.

As a result, as shown in FIG. 5, the pipe 18 is further inserted and inserted into the inside of the binding member 34, so that the insertion length of the pipe 18 can be variably adjusted.

Further, when the cut portion 42 of the crimper member 34 is opened, the cut portion 42 of the crimper member 34 is relatively compressed when it is opened to prevent the frictional coupling force with the pipe 18 from being somewhat weakened The urging force of the airtightness maintaining member 36 strongly pressurizes the cut portion 42 in the direction in which the inner diameter d1 of the presser member 34 is reduced so that the pipe 18 and the presser member 34 It is possible to secure the safety and the bonding force in accordance with the connection between the assemblies, thereby preventing the deterioration of the assembly quality.

Therefore, when the piping connecting structure according to the present invention is used, even if the piping disposed on both sides is fixed, the inner diameter can be changed while the cut portion of the piercing member is opened. Therefore, And a stepped structure in which the piping is brought into contact with each other when the cut portion is pinched. Therefore, it is possible to combine the socket type connection structure and the sleeve type and the socket type connection type.

Further, when the connecting structure for piping of the ship according to the present invention is used, The advantages of the sleeve type and the socket type coupling type as described above can be exerted, and the disadvantages of the sleeve type and the socket type coupling type can be solved.
