The head body is formed by welding a cylindrical middle frame to the lower end opening surface of a bowl-shaped cap, and at least one side surface of the head body has a circular hole and a peripheral edge of the circular article. An annular flange piece that projects outward is provided, and a mouth metal fitting is connected to the opening end surface of the flange piece.

Further, as a method for manufacturing the main body of the fire extinguishing and water sampling port, stainless steel or the same as the stainless steel or the same is formed on the opening end surface of the cap which is obtained by drawing a punching plate made of stainless steel or a material having the same effect. By forming a head body by welding the upper end opening surface of the cylindrical middle frame made of the effect material, by forming a circular hole at at least one position on the side surface, and performing burring on the circular hole, An annular flange piece that projects outward along the peripheral edge of the circular hole is integrally provided, and then a mouth metal fitting is connected to the opening end surface of the flange piece, and stainless steel or stainless steel is attached to the lower end opening surface of the head body. This is characterized in that the upper end opening surface of a cylindrical support made of the same material is connected, and when the mounting portion is formed separately, the mounting member is connected to the lower end opening of the support. . The single-mouthed type has a single mouth on the side of the head, and the double-mouthed type has two mouths on the upper and lower sides of the head or on the left and right sides of a 120 ° angle. It is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present application will be described in detail below with reference to the drawings. FIGS. 1 to 3 show a main body for feeding and collecting water of a single mouth type, which main body is of a bowl-shaped cap 1. A head body 3 formed by welding the upper end opening surface of the cylindrical middle frame 2 to the lower end opening surface, a long pillar 4 welded to the lower end opening surface, and a long pillar 4 welded to the lower end opening portion. The head member 3 has a circular hole 6 and an annular ring projecting outward along the peripheral edge of the circular hole 6 on the side surface of the head body 3. The flange portion 7 is provided, and the mouth metal fitting 8 for connecting the water discharge pipe is welded to the end face of the collar portion. No. 8 is made of weldable stainless steel with strong corrosion resistance.

Specifically, the cap 1 is formed by drawing a disk-shaped punching plate into a bowl shape as shown in FIG. 4A, and has a cylindrical middle frame 2 at the lower end opening surface thereof.
4B is integrally joined to the opening surface of the upper end of the head body 3 to form a head body 3 whose upper surface is curved in an arc shape and which is open at the lower end, as shown in FIG. 4B. Then on its side, as shown in FIG. 4C,
As shown in FIG. 4D, a circular hole 6 is provided, and a flange portion 7 protruding outward by burring is provided on the circular hole 6, and the end surface of the flange portion 7 is provided with a separate hole as shown in FIG. 4E. The mouth metal fitting 8 formed on the body is joined by welding P. In this way, the upper end opening surface of the long column 4 formed in a cylindrical shape is welded to the lower end opening surface of the head body 3 having a single mouth, and then the lower portion is thinned on the inner surface of the lower end portion of the column 4. Formed into a diameter,
The upper portion of a mounting member 5 made of a short tube having a screw 9 attached to the outer periphery thereof is fitted, and the fitting portion is fixed by welding P. Further, at a position below the collar portion 7, the mouth metal fitting 6 is provided.
A mounting screw portion 11 for supporting the chain provided on the lid piece 10 for sealing the is attached.

FIGS. 5 and 6 show the upper and lower twin mouth type feeding and water collecting body, and the difference from the single feeding type water feeding and collecting body is that the length of the middle frame 2 is extended. A vertically long head body 13 is formed, and a circular hole 6 and a collar portion 7 formed by burring are provided at upper and lower positions of a side surface thereof, and a mouth metal fitting 8 is welded to each end surface of each collar portion 7 by welding P. And
The mounting screw portion 11 is provided corresponding to each circular hole 6, and the other configurations are the same.

FIGS. 7 and 8 show a left and right double mouth type feed and water intake body, which differs from the single mouth type water feed and water intake body in that the radius of curvature of the cap 1 is increased. , The upper body 2a of the middle frame 2 is curved in a bowl shape in accordance with the opening surface of the lower end thereof, and the head body 14 is configured by joining these by welding P, and the head body 14 is formed at a left and right angle of about 120 °. A circular hole 6 and a flange portion 7 formed by burring are provided at two locations, and the end fittings 8 are joined to the end faces of the flange portions 7 by welding P, and the left and right circular holes 6 are formed.
Since the mounting screw portion 11 is provided at the intermediate position of, the other configurations are the same. In the above, the welding trace is removed by the surface polishing of the welded portion P.

In each of the above embodiments, the heads 3 and 13 are used.
Although the case where the outer diameters of the column and the column 4 are made equal is shown, as in the conventional configuration, when the column 9 is provided with the screw 9 at the lower end and the mounting portion 15 is directly provided, the column is provided on the installation surface. A column 16 having a small diameter that matches the diameter of the water supply port is used, and the lower portions of the head bodies 3 and 13 are configured to have a small diameter in accordance with the outer diameter dimension thereof. That is, FIG. 9 shows a single-port type feeding and sampling port main body,
When the lower portion 3a of the head body 3 joined to the support column 14 is formed to have a small diameter so as to be equal to the outer diameter of the support column 16, FIG.
No. 0 is the upper and lower twin-necked type of feeding and sampling port main body
4 shows the case where the lower portion 13a of the head body 13 joined to 4 is formed to have a small diameter so as to be equal to the outer diameter of the pillar 16, and although such a configuration is not shown, a left and right double-mouthed feed, It is also applied to the body of the water intake.

In the above-mentioned embodiment, as the most preferable embodiment, the heads 3, 13, 14 and the struts 4, 16, the mounting member 5 and the mouth metal fitting 8 are welded respectively. It goes without saying that the components may be screw-connected to each other as in the conventional case, and in this case as well, a product having excellent corrosion resistance can be provided.

[0012]

As described above, according to the present invention, since it is manufactured from a weldable metal material having strong corrosion resistance, its aesthetic appearance can be maintained for a long period of time and it is extremely economical. Moreover, it is easy to manufacture regardless of whether it is a single-ended type or a double-ended type.
Further, according to the configuration of claim 9, there is an advantage that the screwing work and the screw connection work can be omitted.
