Description

[Detailed description of the invention] [Field of industrial application] The present invention is designed to distribute hot water, gas, etc. using flexible pipes (hereinafter referred to as "flexible pipes"). It concerns a fluid distributor (hereinafter referred to as a header) that is attached to the original part.

[Prior art and its problems] As shown in Figs. 4 and 5, a conventional header has a structure in which a single header body 01 is provided with flexible pipe connection ports 02 in parallel, and a connection port 03 with a pipe 04 is connected to the header body 01. The inflowing fluid is sequentially branched within the header body 01 and flows toward the flexible pipes 05... side.

For this reason, conventional headers have the following drawbacks.

a The flexible pipe connection port 02 requires a space large enough to insert and rotate a tool when tightening the tightening nut 06, so it is necessary to secure a predetermined interval, which results in a long and large size in the horizontal direction.

b Each flexible pipe 05 connects to the flexible pipe connection port 02.
The connection work is time-consuming because it requires tightening the connection.

[Purpose of the present invention] The present invention has been proposed in view of the above-mentioned points, and the present invention is to reduce the size of a header for distributing hot water, gas, etc. and to reduce the trouble of connection by half. It is a purpose.

[Configuration of the present invention] The present invention proposes the following configuration as a means for achieving the above object.

A single installation port for the piping is provided at the rear, a plurality of flexible pipe connection ports are provided at the front, the installation port and the flexible pipe connection ports are communicated with each other inside, and a thread is cut on the outer peripheral surface of the front side. a header body consisting of a header body, a retainer split into two pieces that are respectively fitted into the flexible pipe connection ports with the flexible pipe in between, and a template formed with flexible pipe through holes corresponding to the flexible pipe connection ports of the header body, respectively; A fluid distributor comprising: a tightening nut having an internal thread on its inner surface that is screwed into the thread of the header body, an open front side, and a template engagement collar formed in the open part.

In the above header, connect the attachment port of the header body to the piping, then pass the flexible tubes into the through holes of the template, and then attach the retainer so that 2 to 3 threads of the flexible tubes come out from the ends of the passed flexible tubes. , fit this into the flexible pipe connection port, and screw the tightening nut into the screw of the header body.The tightening nut pushes the template, and the template tightens each retainer into the flexible pipe connection port. By doing this, two to three peaks at the tip of the flexible tube are crushed to maintain airtightness and watertightness, and a gasket is inserted into this part as necessary.

[Embodiments and their effects] Fig. 1 is an exploded perspective view showing a header for city gas distribution in which the above-mentioned present invention is implemented, and 1 is a circular header body. A single attachment port 2 is provided, and four flexible pipe connection ports 3 are formed in the center and around this on the smooth front surface, and the connection port 3 and the attachment port 2 are communicated through communication paths 4, respectively. It has a configuration in which a screw 5 is provided on the outer periphery of the front side.

6... is a gasket, and the flexible pipe connection port 3
inserted into the bottom of the

7 is a two-piece retainer with a ridge 7' formed on the inner surface corresponding to the ridge of the flexible tube.

8 is a template in which a through hole 9 is provided at a position corresponding to the flexible pipe connection port 3 of the header main body 1. The through hole 9 engages with the retainer 7, but has an inner diameter that allows the flexible tube to pass freely through it.

Reference numeral 10 denotes a tightening nut, and the nut 10 has an internal thread 10' cut on the rear inside thereof, and a collar 11 on the front side that engages around the template 8.
A hole 12 is formed therein.

Figure 2 shows gas piping 13 using the above header.
shows a state where the flexible pipe 14 for distribution is connected,
The header body 1 is connected to a gas pipe 13 using its attachment port 2.

Next, pass the flexible pipe 14 through the tightening nut 10,
Next, the flexible tubes 14 are passed through the through holes 9 of the template 8, and then the retainers 7 are inserted into the flexible tubes 14.
2 or 3 so that two or three peaks protrude from the tip side of the tube, and fit them into the flexible tube connection port 3, respectively. In addition,
The packing 6 is made to correspond to the flexible pipe connection port 3 of the header body 1 in advance.

After the flexible pipe 14 has been fitted into the flexible pipe connection port 3 in this manner, the tightening nut 10 is then tightened. As the tightening nut 10 is tightened, the collar 11 engages around the template 8, and the template 8 engages the tips of the retainers 7, pushing the retainers 7 into the flexible pipe connection port 3. go. When the retainer 7 is pushed in, two to three peaks of the flexible tube 14 that were exposed ahead are crushed. When the peak is crushed, the retainer 7 stops entering, and the tightening nut 10 is sufficiently tightened to complete the connection work.

Incidentally, if the tightening nut 10 is not connected to the flexible pipe 14 side and the flexible pipe 14 is short, the flexible pipe 14 may be passed through the hole 12 later and tightened.

[Effects of the present invention] As described above, the header according to the present invention has a plurality of flexible pipe connection ports on the front of the header body, so that the entire header can be tightened at the same time using one template and one tightening nut. This allows the flexible tubes to be brought as close together as possible, and is in a state where they are just bundled, so they are not elongated in the lateral direction as in the conventional case, and the overall size is reduced. In addition, since it is only necessary to tighten one tightening nut, there is no need to tighten each flexible pipe one by one as in the conventional method, and the effort required for connection work can be halved compared to the conventional method.
