[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-5240 Summary of the Invention [Problem to be solved by the invention]

[0006] Conventionally, when installing automatic valve devices in tunnels, the work of storing them in storage boxes has been carried out on-site. This has resulted in the problem of taking a long time to install the automatic valve devices, which has led to a long construction period. In particular, when installing automatic valve devices in tunnels that are already open and in operation, traffic restrictions such as road closures are required, which means the impact of long construction periods is significant.

[0007] SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide an automatic valve device that can shorten the installation work period. [Means for solving the problem]

[0008] The present invention provides an automatic valve device in which an automatic valve body is stored in a storage box and installed on a building, The automatic valve includes the automatic valve body and the storage box, a primary side connecting pipe connected to a lower part of the automatic valve body, a base fixed to a lower part of the storage box, and a support member provided on the primary side connecting pipe, and the storage box is fixed to the base, The support member is fixed to the base, In a state where the automatic valve body is stored in the storage box and the support member supports the primary side connecting pipe to support the automatic valve body, The automatic valve device is characterized by having a fixed structure in which the automatic valve body, the primary side connecting pipe, the storage box, and the frame are integrated.

[0009] In the present invention, the support member is provided between the automatic valve body and the primary side connection The base may have a strength sufficient to support the load of the pipe. The base may have a strength sufficient to support the load of the automatic valve main body, the primary side piping, and the storage box. The storage box may be provided with a support portion to which a drainage receiving portion for receiving drainage from the drainage means connected to the automatic valve main body is fixed. A temporary base may be provided on the lower part of the base when assembling the device. The temporary base may have a height sufficient to raise the entire device so that the lower end of the primary side connecting pipe protruding below the base is suspended in the air. The lower part of the base may be provided with fixing members, instead of the temporary base, that are fixed to the lower part of the base and to the installation surface of the device during installation. [Effects of the Invention]

[0010] In this invention, the automatic valve body, primary side connecting pipe, storage box, and stand can be assembled as a unit in advance at a factory or the like before installation at the site. Therefore, the work that was conventionally performed on site can be eliminated or reduced, and the work time at the site can be shortened.

[0011] Therefore, according to the present invention, an automatic valve device can be obtained that can shorten the installation construction period. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] An embodiment of the automatic valve device of the present invention will be described with reference to Figures 1 to 6, taking as an example a case where the automatic valve device is applied to a water spray facility for a tunnel. Note that the present invention can also be applied to automatic valve devices other than those installed in tunnels, as long as the automatic valve device is stored in a storage box and installed in a structure.

[0014] [Water spray equipment] The water spray equipment is equipped with a water spray head that is installed at a high location, such as above the ceiling or side walls of the tunnel, and an automatic valve device that is installed in the middle of the vertical piping that supplies water to the water spray head.In the event of a fire, the valve of the automatic valve body opens and water is sprayed from the water spray head, preventing the fire from spreading and protecting structures (ceilings, walls, etc.).

[0015] [Automatic valve device] In the water spray equipment, the automatic valve device is connected to the vertical primary pipe located below (the base end leads to the water supply source) and the vertical secondary pipe located above (the end end leads to the water spray head), and the automatic valve body is stored in a storage box and installed along the side wall of the tunnel. The automatic valve device of this invention can be used as the automatic valve device equipped in such water spray equipment.

[0016] Figures 1 to 6 show an example of an embodiment of the automatic valve device of this invention, where Figure 1 shows the automatic valve device assembled as a unit, with a temporary stand installed under the stand during assembly, Figure 2 shows the automatic valve device in Figure 1 with a fixing member installed under the stand during installation instead of the temporary stand, Figure 3 shows the primary side connecting pipe alone, Figure 4 shows the stand alone, Figure 5 shows the temporary stand alone, and Figure 6 shows the fixing member.

[0017] ·Entire device The automatic valve device 1 comprises a storage box 2, a stand 3 fixed to the bottom of the storage box 2, an automatic valve body 4 stored within the storage box 2, a primary side connecting pipe 5 connected to the bottom of the automatic valve body 4, and a secondary side connecting pipe 6 connected to the top of the automatic valve body 4 (see Figures 1 and 2). When installed in a tunnel, although not shown, the primary side connecting pipe 5 is connected to a vertical primary side pipe located below (the base end leads to the water supply source; not shown), and the secondary side connecting pipe 6 is connected to a vertical secondary side pipe located above (the end end leads to the water spray head; not shown).

[0018] The secondary side connecting pipe 6 can be omitted. In other words, the secondary side external piping may be connected directly to the secondary side connecting portion of the automatic valve body 4 without providing the secondary side connecting pipe 6.

[0019] ·Integrated structure A support member 7 is fixed to the primary side connecting pipe 5 (see Figures 1 to 3). The support member 7 is fixed to a base 3 which is fixed to the bottom of the storage box 2 (see Figures 1 and 2). In other words, the automatic valve device 1 has a fixed structure in which the automatic valve main body 4, primary side connecting pipe 5, secondary side connecting pipe 6, storage box 2, and base 3 are integrated.

[0020] This allows the storage box 2, stand 3, automatic valve body 4, primary side connecting pipe 5, and secondary side connecting pipe 6 to be assembled as a unit in a factory or the like before installation on site. This eliminates or reduces the need to perform work that was previously done on site. In other words, the time spent on site can be shortened, and the installation construction period can be shortened.

[0021] Furthermore, even if the storage box 2, stand 3, automatic valve body 4, primary side connecting pipe 5 and secondary side connecting pipe 6 are assembled as a unit as described above, the load of heavy objects such as the automatic valve body 4, primary side connecting pipe 5 and secondary side connecting pipe 6 can be prevented from being applied to the storage box 2, and deformation such as distortion of the storage box 2 due to the load of these heavy objects can be prevented.

[0022] -Specific examples of each component Accessories Here, the automatic valve device 1 further includes various accessories, such as a pilot valve 15 (electric valve), a pressure switch 16, and a drain valve 17, which are provided in the automatic valve main body 4, and a panel heater (not shown), a terminal box 18, and a drain receiver 19, which are provided in the storage box 2 (see Figures 1 and 2).

[0023] The installation of these accessories and the connection of the wiring (wiring for electrical components such as the pilot valve 15, pressure switch 16, and panel heater) to the terminal box 18 can also be carried out in advance at a factory, etc. In other words, these accessories can be unitized together with the storage box 2, stand 3, automatic valve body 4, primary side connecting pipe 5, and secondary side connecting pipe 6.

[0024] Storage box The storage box 2 has a box-like shape with an openable front side (see Figures 1 and 2). The automatic valve body 4 is stored in the storage box 2 with a primary side connecting pipe 5 and a secondary side connecting pipe 6 connected to them, with the two pipes standing upright (see Figures 1 and 2).

[0025] A notch 2d is provided in the center of the bottom plate 2a of the storage box 2, through which the primary side connecting pipe 5 passes (see the phantom line in Fig. 4(b)). Furthermore, the bottom plate 2a is also provided with notches 2e on the inside of both left and right ends (slightly inside the left and right ends) that serve as access points when fixing the base 3 to a temporary base 10 or fixing brackets 11 (described later) (see the phantom line in Fig. 4(b)).

[0026] The bottom plate 2a of the storage box 2 has fixing portions at both left and right ends for fixing to the stand 3, and bolt insertion holes 2aa are provided in these fixing portions (see the imaginary line portion in Figure 4(c)). Furthermore, the bottom plate 2a has a support portion 20 for supporting the drainage receiving portion 19 (see Figures 1 and 2).

[0027] The back plate 2c of the storage box 2 is provided on the inner surface with the heater (not shown) and terminal box 18 (see FIGS. 1 and 2).

[0028] Automatic valve body The automatic valve body 4 has a connection part at the bottom for connecting to the primary side connecting pipe 5 and a connection part at the top for connecting to the secondary side connecting pipe 6. In the example shown, the primary side connecting pipe 5 is connected to the bottom connecting part by a housing joint 8, and the secondary side connecting pipe 6 is connected to the top connecting part by a flange joint 9 (see Figures 1 and 2).

[0029] Primary side connecting pipe The primary side connecting pipe 5 has a length that, when assembled, penetrates the bottom plate 2a of the storage box 2 and the lower end 5a protrudes downward beyond the frame 3 (see FIGS. 1 and 2).

[0030] Support member The support members 7 are provided in a pair on the left and right sides of the primary side connecting pipe 5, and each has a fixing plate 7a where a fixed portion with the pedestal 3 is provided, and a reinforcing plate 7b that reinforces the fixing plate 7a (see FIGS. 1 to 3). The fixing plate 7a is fixed to the side of the primary side connecting pipe 5 in a substantially horizontal orientation, and has vertical bolt insertion holes 7aa in the part where it is fixed to the pedestal 3, and the reinforcing plate 7b is fixed to the side of the primary side connecting pipe 5 and the upper part of the fixing plate 7b in a substantially vertical orientation (see FIGS. 1 to 3).

[0031] The support member 7 is fixed to the frame 3 and supports the primary side connecting pipe 5, and also supports the automatic valve body 4 and the secondary side connecting pipe 6, etc. Therefore, in addition to the fixing plate 7a, a reinforcing plate 7b is provided, and each fixing portion (the fixing portions of the fixing plate 7a and the reinforcing plate 7b to each other and to the side portion of the primary side connecting pipe 5) is firmly fixed by welding or the like.

[0032] The support members 7 may be provided on only one of the left and right sides of the primary side connecting pipe 5, but providing them on both the left and right sides will make the support structure more stable. Also, instead of a pair on the left and right, a pair on the front and back may be provided, or a pair on each of the front, back, left and right, i.e., four directions.

[0033] Mounting The storage box 2 and the support member 7 are fixed to the upper part of the frame 3, and the loads of the storage box 2, the automatic valve body 4, the primary side connecting pipe 5, the secondary side connecting pipe, etc. act on the frame 3 during assembly in a factory, etc. Therefore, the frame 3 is provided with a strength capable of supporting these loads.

[0034] In the illustrated example, the stand 3 is provided as a frame-like structure having such strength, and is composed of an outer frame portion 3a having a rectangular shape when viewed from above that corresponds to the shape of the storage box 2, an upper bridge portion 3b installed in the front-to-rear direction above the central portion of the outer frame portion 3a, and a lower bridge portion 3c installed in the front-to-rear direction below the inner portions on both left and right ends of the outer frame portion 3a (portions slightly inside the left and right sides). The upper bridge portion 3b and the lower bridge portion 3c are made of a single channel material.

[0035] As the structural material for forming the frame-like structure of the frame 3, steel materials such as angle members and channel members can be used.

[0036] The upper left and right end portions (both left and right side portions) of the outer frame portion 3a are provided with fixing portions for connection to the storage box 2, and vertical bolt insertion holes 3aa are provided in these fixing portions. The upper bridge portion 3b is provided with fixing portions for connection to the support member 7, and vertical bolt insertion holes 3ba are provided in these fixing portions (see Figure 4(b)).

[0037] When fixing the storage box 2 to the mount 3, a bolt (not shown) is inserted from above through the bolt insertion hole 2aa of the storage box 2 and the bolt insertion hole 3aa of the mount 3, and is screwed onto a nut 3ab on the underside (back surface) of the bolt (not shown) (see FIG. 4(a)), and they are fastened together to fix the storage box 2 and the mount 3. Similarly, when fixing the support member 7 to the mount 3, a bolt (not shown) is inserted from above through the bolt insertion hole 7aa of the support member 7 and the bolt insertion hole 3ba of the mount 3, and is screwed onto a nut 3bb on the underside (back surface) of the bolt (not shown) (see FIG. 4(a)), and they are fastened together to fix the storage box 2 and the mount 3.

[0038] Here, it is preferable that the nuts 3ab, 3bb that screw into the bolt insertion holes 3aa, 3ba of the mount 3 on the underside are fixed to the underside in advance by welding or the like (see FIG. 4(a)). This makes it easy to screw in and tighten the bolts.

[0039] When assembling the frame 3 in a factory or the like, a temporary frame 10, which will be described later, is fixed to the bottom of the frame 3, and when installing the frame 3 on site, a fixing bracket 11, which will also be described later, is fixed instead of the temporary frame 10. The lower bridge portion 3c is provided with a fixing portion for the temporary frame 10 or the fixing bracket 11, and a vertical bolt insertion hole 3ca is provided in the fixing portion (see FIG. 4(b)).

[0040] Temporary stand During assembly in a factory or the like, a temporary pedestal 10 is fixed to the bottom of the pedestal 3 (see FIG. 1).

[0041] When the temporary stand 10 is assembled in a factory or the like, the loads of the storage box 2, stand 3, automatic valve body 4, primary side connecting pipe 5, secondary side connecting pipe 6, etc. act on the temporary stand 10. Therefore, the temporary stand 10 is provided with a strength capable of supporting these loads.

[0042] In the illustrated example, the temporary cradles 10 are provided as a pair fixed to the inside of both left and right ends of the lower part of the cradle 3 (see FIG. 1).

[0043] In the illustrated example, each has a rectangular frame-like structure when viewed from the side (see Figure 5(b)), and the upper member 10a has a fixed part for connection to the base 3, and a vertical bolt insertion hole 10aa is provided in this fixed part (see Figure 5(a)).

[0044] When fixing the temporary base 10 to the base 3, a bolt (not shown) is inserted from below through the bolt insertion hole 10aa of the temporary base 10 and the bolt insertion hole 3ca of the base 3, and then screwed onto a nut (not shown) on the top (surface) side, and the bolts are tightened together to fix them in place.

[0045] The temporary pedestal 10 has a height exceeding the protruding dimension of the lower end 5a of the primary side connecting pipe 5 protruding below the pedestal 3, and has a height that allows the entire device to be raised so that the lower end 5a is suspended in the air (see FIG. 1). This allows the assembly work to be performed in a factory or the like without the lower end 5a of the primary side connecting pipe 5 touching the ground. This state can also be maintained during storage, transportation, etc. after assembly.

[0046] The temporary gantry 10 may also be made of steel materials such as angle members and channel members.

[0047] Support part for drainage receiver As described above, the storage box 2 has a support section 20 on the bottom plate 2a for the drainage receiving section 19 that receives drainage from the drainage valve 17 connected to the automatic valve main body 2 (see Figures 1 and 2). The support section 20 is provided upright on the bottom plate 2a, and a pipe section 19b provided below the funnel section 19a of the drainage receiving section 19 is fixed by a fixing member such as a pipe clamp, thereby supporting and fixing the drainage receiving section 19 (see Figures 1 and 2).

[0048] When assembling in a factory, etc., if the drainage receiving part 19 is also fixed to the support part 20, the drainage receiving part 19 can be unitized together with the storage box 2, the stand 3, the automatic valve body 4, the primary side connecting pipe 5 and the secondary side connecting pipe 6.

[0049] In addition, the pipe portion 19b of the drainage receiving portion 19 also has a length that penetrates the bottom plate 2a of the storage box 2 and its lower end portion extends beyond the frame 3 and protrudes downward when assembled (see Figures 1 and 2), but the temporary frame 10 also has a height that exceeds the downward protrusion dimension of the lower end portion of the pipe 19b. In other words, the temporary frame 10 has a height that allows the entire device to be raised so that the lower end portion of the pipe 19b also floats in the air (see Figure 1).

[0050] Fixing bracket (an example of a fixing member) At the time of installation on site, a fixing bracket 11 (an example of a fixing member) is fixed to the lower part of the mount 3 instead of the temporary mount 10 fixed to the lower part of the mount 3 (see FIG. 2).

[0051] In the illustrated example, the fixing brackets 11 are provided as a pair on the left and right sides to be fixed to the bolt insertion holes 3ca on the inside of both the left and right ends of the lower part of the base 3 that was used to attach the temporary base 10 when the automatic valve device 1 was removed (see Figure 2).

[0052] In the illustrated example, each member has a triangular frame shape when viewed from the side (see FIG. 6(c)), and the upper member 11a is provided with a fixing portion for connection to the frame 3, with vertical bolt insertion holes 11aa provided in this fixing portion (see FIG. 6(a)). Also, the rear member 11b, which extends downward from the upper member 11a at a substantially right angle, is provided with a fixing portion for connection to the mounting surface of the automatic valve device 1 at the site, such as the wall of a tunnel, with longitudinal bolt insertion holes 11ba provided in this fixing portion (see FIG. 6(b)).

[0053] When fixing to the wall of a tunnel, etc., a bolt (not shown) embedded in the wall is inserted from the rear into the bolt insertion hole 11ba of the fixing bracket 11, and screwed onto a nut (not shown) on the inner surface, and then they are tightened together to fix it.

[0054] When fixing the fixing bracket 11 to the mounting base 3, as with the temporary mounting base 10, a bolt (not shown) is inserted from below through the bolt insertion hole 11aa of the fixing bracket 11 and the bolt insertion hole 3ca of the mounting base 3, and then screwed onto a nut (not shown) on the top (surface) side, and the bolts are tightened together to fix them in place.

[0055] The material for forming the fixture 11 may also be steel such as angle material or channel material.

[0056] ·Position adjustment function The bolt insertion hole 3ca of the mounting base 3 is a long hole in the front-to-rear direction (see Figure 4(c)), the bolt insertion hole 11aa provided in the upper member 11a of the fixing bracket 11 is a long hole in the left-to-right direction (see Figure 6(a)), and the bolt insertion hole 11ba provided in the rear member 11b of the fixing bracket 11 is a long hole in the up-down direction (see Figure 6(b)).

[0057] That is, the mount 3 is fixed to the fixture 11 so that its position can be adjusted in the front-to-back and left-to-right directions, and the fixture 11 is fixed to the wall surface of a tunnel or the like so that its position can be adjusted in the up-down direction.

[0058] As a result, even when the automatic valve device 1 is unitized as described above, when it is installed on site, its position can be adjusted in three directions - front to back, left to right, and up to down - between the base 3 and the fixing bracket 11, and the storage box 2 can be installed so that it is parallel to the inspection path or horizontal. [Configuration change example] Although an example of an embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and modifications to the configuration are possible within the scope of the gist of the invention.
