Description

[Detailed Description of the Invention] The present invention is a header unit for pipe branching provided in a pipe of a heating facility or the like in which hot water boiled in a boiler or the like is circulated through a pipe to a heating device such as a fan coil or a floor heater. Regarding improvements to the device.

With the spread of central heating that circulates hot water, a means for heating by circulating hot water boiled by a water heater such as a boiler to a heating device such as a fan coil or floor heater installed in each room of a house through piping. Has been used.

In this heating means, the hot water circulated in each heating device is usually used in order to simplify the entire construction of the heating facility.
Attach a header (branch pipe) to the source of the pipe that connects to a water heater such as a boiler that becomes a heat source machine, and install each branch at each of the branch-shaped branch connection ports provided in this header. A branching method (header method) is adopted in which each pipe for circulating hot water to the heating equipment arranged in is connected.

By the way, the header used in this way is usually formed in a pipe shape to be connected to a main pipe of a pipe connected to a water heater such as a boiler, as shown in FIGS. 1 and 2. The header main body 1 is provided with a plurality of branch-shaped branch connection ports 10 ... With an axial direction X-X thereof orthogonal to the axial direction Y-Y of the header main body 1 in the axial direction Y- of the header main body 1. It is configured by arranging them in parallel along the Y and mounting them integrally (or integrally).

This header is, of course, a header a on the outward path for connecting the header body 1 to the hot water outlet side pipe of a water heater such as a boiler, and a header body for the hot water return port of the water heater. There is a header b on the return path to which 1 is connected. Usually, the header b on the return path is provided with the base body 1 of each branch connection port 10 provided in parallel with the header body 1 of the return path.
Since the valve mechanism v for controlling the flow rate of the hot water circulated in each heating device is incorporated in 0a (the valve mechanism v for flow rate control may be provided in the header a on the outward path,
In order to make the description easier to understand, the header provided with the valve mechanism v will be described below as the header b on the return path side. ) Finally, a header b shown in the upper side in FIGS. 1 and 2 in a form in which the valve mechanism v is incorporated in the base end portion 10a of the branch connection port 10, and FIG. 1 and FIG. 2), a header a in which the valve mechanism v is not incorporated in the base end portion 10a of the branch connection port 10 and a header a in which the valve mechanism v is not incorporated.

The headers a and b of these two forms are usually made to be difficult because the assembling of them is troublesome if they are separately produced when they are produced and combined when they are used. As shown in FIG. 2 and FIG. 2, those header bodies 1 and 1 are made into a header unit A which is integrally and continuously combined by a connecting member B, and the connecting member B is connected to a building by a set screw C. By assembling and supporting the supporting member D provided in the above, the assembling is performed at a predetermined position so that the assembling can be performed rationally.

However, the header unit A configured in this way is
Depending on the configuration of the pipe, the axial direction X-X of the branch connection port 10 of the header a on the outward path without the valve mechanism v is set to the axial direction X-X of the branch connection port 10 of the header b on the return path that incorporates the valve mechanism v. -X may be desired to be in a state parallel to that, and for that reason, the branch connection port 10 of the header a on the outward path 10
, As shown by the chain line in FIG. 2, there is a problem in that it is necessary to make a structure in which the header b on the return path is projected in the horizontal direction in parallel with the branch connection port 10. There is a problem that the assembly of the header unit A by the set screw C to the member D becomes unstable because the set screw C in only one direction is used.

The present invention has been made in order to solve these problems occurring in the conventional means, and the header unit A is projected in the direction perpendicular to the branch connection port 10 provided in the header a on the outward path of the header unit A. (EN) A new header unit device is provided, which is capable of firmly assembling and supporting the header unit A with respect to the support member D while being capable of switching between two states, that is, a state in which the header unit A projects and a state in which the header unit A projects in the horizontal direction. The purpose is to

As a result, in the header a on the outward path, the first locking piece 2a of the header a projects toward the front side,
The locking piece 2b of the above is projected upward, and the branch connection port 10 is projected rearward.

Next, from this state, the header a on the outward path is turned 180 degrees around the axis line in the vertical direction orthogonal to the axis line of the header body 1 so that the left and right sides of the header a are interchanged. Then,
As shown in FIG. 8, the header a on the outward path has a second
The locking piece 2b of the first locking piece 2b projects upward and the first locking piece 2a projects rearward.

Next, in this state, the second locking piece 2b is connected to the connecting piece 3 of the header b on the return path side by the connecting screw 40 to assemble into the header unit A, which is assembled with the set screw C to attach the supporting member D. If it is assembled to the assembly seat 52 of the portion 51 and set, the first engaging piece 2a, which has become idle, becomes
As shown in the figure, the state is along the lower surface of the horizontal wall 51 of the assembling portion 51 of the supporting member D. Therefore, as in the case described above, another set screw C ′ is inserted into the screw hole 31 of the first locking piece 2a which has become the play, and the second mounting seat 53 provided on the horizontal wall 51b is inserted. If screwed and fixed, the header unit A is firmly supported by the horizontal set screw C and the vertical set screw C'as shown in FIG. It can be attached to the member D.
