A pipe for introducing a fluid for introducing a fluid (water) into the header is connected to one end of the header in the axial direction.

Japanese Patent Laid-Open No. 9-144082

  However, conventionally, when connecting a pipe for introducing a fluid to a header, the direction of the pipe is matched with the axial direction of the header. Therefore, the direction (orientation) of the pipe for fluid introduction can be easily changed, such as when there is no space to bend the pipe around or around the header installation place, or when existing pipes must be reused for renovation, etc. If this is not possible, it may be difficult to connect the header and the pipe.

  In particular, when the pipe for introducing the fluid is a pipe made of vinyl chloride resin (hereinafter, referred to as “PVC pipe” as appropriate), it is difficult to bend the pipe. Adjusted. Therefore, the connection work between the header and the piping becomes very complicated, leading to an increase in the number of parts required for the construction.

  The present invention has been made in view of such a background, and provides a connecting member for a header and a header that can easily connect the fluid introduction member of the header and the pipe for fluid introduction with a simple configuration. It is what.

  The header connecting member according to the first aspect of the present invention is used in a header including a fluid introducing member that introduces fluid and a main body that discharges the fluid introduced from the fluid introducing member in a plurality of directions. A connecting member that connects the fluid introduction member and the main body, and is constituted by at least one connecting piece and is connected to the main body so as to be rotatable relative to the main body. A connecting flow path that changes the flow direction between the fluid introduction flow path formed inside the fluid introduction member and the main body flow path formed inside the main body is formed inside. It is characterized by.

  The connecting member for a header of the present invention is disposed between the fluid introduction member and the main body portion of the header. The connection flow path of the connection piece constituting the connection member changes the flow direction between the fluid introduction flow path of the fluid introduction member and the main body flow path of the main body portion. Further, the connecting member and the main body are configured to be relatively rotatable at the connecting portion between them.

  Therefore, the positional relationship between the fluid introduction member (fluid introduction flow path) and the main body portion (main body flow path) can be adjusted in various directions via the connection member configured by the connection piece. For example, the direction (orientation) of the fluid introduction member (fluid introduction flow path) can be easily changed with respect to the main body portion (main body flow path). Thereby, the direction (direction) of the fluid introduction member (fluid introduction flow path) can be easily adjusted in accordance with the direction (direction) of the fluid introduction pipe connected to the fluid introduction member. As a result, the connection between the fluid introduction member of the header and the pipe for fluid introduction becomes easy.

  In particular, when piping that is difficult to bend is used, if there is no space to bend the pipe around the header installation location or around it, or to place a member (for example, an elbow member) to change the direction of the pipe, remodeling, etc. In the case where the direction (orientation) of the pipe for introducing the fluid cannot be easily changed, such as when the existing pipe must be reused, the above-described effects can be effectively exhibited. Further, since there is no need to change the direction of the flow path in the fluid introduction member, the structure of the fluid introduction member itself can be simplified.

  The header according to the second aspect of the present invention is composed of a fluid introduction member for introducing a fluid, a main body portion constituted by at least one header piece, and at least one connection piece, and the fluid introduction A connecting member for connecting the member and the main body, a fluid introduction channel is formed in the fluid introduction member, and a main channel formed in a predetermined direction is formed in the header piece.

A connecting channel that changes the channel direction is formed between the fluid introducing channel of the fluid introducing member and the main body channel of the main body, and the connecting member and the main body can be rotated relative to each other. Connected And wherein the door.

  In the header of the present invention, a connecting member is disposed between the fluid introduction member and the main body. The connection flow path of the connection piece constituting the connection member changes the flow direction between the fluid introduction flow path of the fluid introduction member and the main body flow path of the main body portion. In addition, the connecting member and the main body are configured such that the connecting piece and the header piece can be rotated relative to each other at the connecting portion. By adopting such a configuration, the same operational effects as those of the header connecting member described above can be obtained.

  As described above, according to the present invention, it is possible to provide a header connecting member and a header that can easily connect the fluid introduction member of the header and the pipe for fluid introduction with a simple configuration.

  In the connecting member for the header and the header, the connection piece may be formed by bending the connection flow path in an L shape. In this case, it becomes easy to adjust the positional relationship between the fluid introduction member (fluid introduction flow path) and the main body portion (main body flow path) in various directions via the connection member constituted by the connection piece. . This facilitates connection between the fluid introduction member of the header and the fluid introduction pipe.

  Moreover, the said connection member is comprised by two said connection pieces, and these connection pieces may be connected so that relative rotation is possible. In this case, the fluid introduction member (fluid introduction passage) and the main body (main body passage) are connected via a connection member configured by connecting two connection pieces each having an L-shaped connection passage. The positional relationship can be adjusted in all directions, front and rear, left and right, and up and down. This further facilitates the connection between the header fluid introduction member and the fluid introduction pipe.

In this case, in the main body, the direction (direction) of the branch flow path of each header piece can be adjusted for each header piece. Thereby, for example, it becomes easy to adjust the direction (direction) of the branch flow path of each header piece according to the connection direction of the pipe for fluid discharge (fluid supply) connected to the main body.

  As shown in FIGS. 1 and 4, in the header 1 having the above-described configuration, the fluid introduction member 7 has a fluid introduction channel 71. The main body 21 has a main body channel 211 configured by connecting the main channels 311 of the four header pieces 3. The flow channel direction (Y direction) of the main body flow channel 211 is a direction orthogonal to the flow channel direction (X direction) of the fluid introduction flow channel 71. The L-shaped connection flow channel 41 of the connection piece 4 that connects the fluid introduction member 7 and the main body portion 21 is connected to the main body flow of the main body portion 21 from the flow direction (X direction) of the fluid introduction flow channel 71 of the fluid introduction member 7.

  In the header 1, the fluid introduction member 7 and the connection piece 4 of the connection member 20 are configured to be relatively rotatable with the central axis 700 of the fluid introduction member 7 (fluid introduction channel 71) as a base axis. Therefore, for example, by rotating the connecting member 20 (connecting piece 4) with respect to the fluid introducing member 7, the axial direction of the main body portion 21 (the flow direction of the main body flow channel 211) is changed to the axial direction of the fluid introducing member 7.

It is configured to be possible. Therefore, for example, by rotating the connecting member 20 (connecting piece 4) with respect to the main body 21, the axial direction of the fluid introduction member 7 (the flow direction of the fluid introduction flow path 71) is changed to the axial direction of the main body 21. It can be freely changed in a direction orthogonal to the (Y direction).

  In the main body 21, adjacent header pieces 3 are configured to be relatively rotatable with the central axis 210 of the main body 21 (main body channel 211) as a base axis. Therefore, by rotating the header piece 3, the direction of the branch flow path 321 of the header piece 3 can be freely changed in a direction orthogonal to the axial direction (Y direction) of the main body portion 21.

Next, the effect in the header 1 of this embodiment is demonstrated.
In the header 1 of the present embodiment, a connecting member 20 is disposed between the fluid introduction member 7 and the main body portion 21. The connection flow path 41 of the connection piece 4 constituting the connection member 20 changes the flow path direction between the fluid introduction flow path 71 of the fluid introduction member 7 and the main body flow path 211 of the main body portion 21. Moreover, the connection member 20 and the main-body part 21 are comprised so that the connection piece 4 and the header piece 3 can rotate relatively in the connection part of both.

  Therefore, the positional relationship between the fluid introduction member 7 (fluid introduction flow channel 71) and the main body portion 21 (main body flow channel 211) can be adjusted in various directions via the connection member 20 configured by the connection piece 4. It becomes possible. For example, the direction (direction) of the fluid introduction member 7 (fluid introduction passage 71) can be easily changed with respect to the main body portion 21 (main body passage 211). Thereby, the direction (direction) of the fluid introduction member 7 (fluid introduction channel 71) can be easily adjusted according to the direction (direction) of the fluid introduction pipe 11 connected to the fluid introduction member 7. As a result, the connection between the fluid introduction member 7 of the header 1 and the fluid introduction pipe 11 is facilitated.

  In particular, when piping that is difficult to bend is used, if there is no space to bend the piping around the installation location of the header 1 or to arrange a member for changing the direction of the piping (for example, an elbow member) In the case where the direction (orientation) of the fluid introduction pipe 11 cannot be easily changed, such as when the existing pipe must be reused, the above-described effects can be effectively exhibited.

  Moreover, since it is not necessary to change the direction of the flow path (fluid introduction flow path 71) in the fluid introduction member 7, the structure of the fluid introduction member 7 itself can be simplified. In this embodiment, the cylindrical fluid introduction member 7 is used, and the fluid introduction passage 71 formed in the fluid introduction member 7 is also linear.

  Moreover, in this embodiment, the connection piece 4 is formed by bending the connection channel 41 in an L shape. Therefore, the positional relationship between the fluid introduction member 7 (fluid introduction flow channel 71) and the main body portion 21 (main body flow channel 211) can be adjusted in various directions via the connection member 20 configured by the connection piece 4. It becomes easy. This facilitates the connection between the fluid introduction member 7 of the header 1 and the fluid introduction pipe 11.

  Moreover, the main-body part 21 is comprised by the some header piece 3, and the header pieces 3 are connected so that relative rotation is possible. Therefore, in the main body 21, the direction (direction) of the branch flow path 321 of each header piece 3 can be adjusted for each header piece 3. Thereby, for example, it becomes easy to adjust the direction (direction) of the branch flow path 321 of each header piece 3 according to the connection direction of the fluid discharge pipe 12 connected to the main body 21.

  As described above, according to the present embodiment, there is provided the header connecting member 20 and the header 1 which can be easily connected to the fluid introducing member 7 of the header 1 and the fluid introducing pipe 11 with a simple configuration. be able to.
