[0008] (Findings that formed the basis of this disclosure) At the time the inventors arrived at the idea of ​​the present disclosure, there was a technology in which shutoff valves, such as solenoid valves and motor-operated valves, installed in shutoff valve kits each had a coil that drove the valve element. Because these coils have a set service life, coil replacement is required as needed after a certain period of time has elapsed. However, with the conventional technology, the shutoff valve kit is fixed to the ceiling of the room where it is installed, for example, with a hanging bolt. Therefore, when replacing the coil, it is necessary to do so in the narrow space between the ceiling of the room and the shutoff valve kit, making the coil replacement difficult. Therefore, the present disclosure provides a shutoff valve kit that allows for easy replacement of a coil provided in a shutoff valve such as a solenoid valve or an electric valve.

[0009] Hereinafter, embodiments will be described in detail with reference to the drawings. However, in some cases, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or redundant explanation of substantially the same configuration may be omitted. The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0010] In the explanation, unless otherwise specified, directions such as front, back, left, right, and up and down are based on the shutoff valve kit 1 in Figure 1. Note that the symbol UP indicates upward, the symbol FR indicates forward, and the symbol R indicates right. Although not shown, the opposite direction of the symbol UP indicates downward, the opposite direction of the symbol FR indicates backward, and the opposite direction of the symbol R indicates left.

[0011] (Embodiment 1) [1-1.Configuration] FIG. 1 is a perspective view of a shutoff valve kit 1. FIG. The shutoff valve kit 1 is a box having a substantially rectangular parallelepiped appearance. The shutoff valve kit 1 includes a housing 10 that houses a solenoid valve 17 (an example of a first shutoff valve) and an electric valve 18 (an example of a second shutoff valve) described below, an electrical box 11 in which a circuit board 29 and a supercapacitor 28 described below are disposed, a top plate 12 that covers the top of the housing 10 and the electrical box 11, and a front plate 13 that covers the top and front of the electrical box 11.

[0012] Approximately L-shaped hanging fittings 14 are attached to both the left and right side surfaces of the housing 10. Hanging bolts (not shown) are fixed to the hanging fittings 14. In this way, the shutoff valve kit 1 is hung and supported on the ceiling surface of the room where it is installed. In the housing 10, a first pipe 15 and a second pipe 16 are arranged so as to penetrate both the left and right side surfaces of the housing 10 while being covered with a heat insulating material 35. In this embodiment, the first pipe 15 is a liquid pipe, and the second pipe 16 is a gas pipe.

[0013] Fig. 2 is an exploded perspective view of the housing 10. Fig. 3 is a cross-sectional view of the shutoff valve kit 1, taken along line III-III in Fig. 1. The housing 10 is divided into two parts, front and rear, by a front member 10a and a rear member 10b.

[0014] The front member 10a is an integral part formed by a front portion 41 that forms the lower part of the front surface of the housing 10, a left front portion 43 that forms the front portion of the left side of the housing 10, and a right front portion 45 that forms the front portion of the right side of the housing 10. The front portion 41, the left front portion 43, and the right front portion 45 are formed by bending the front member 10a. The front portion 41 has bending portions that bend approximately vertically from the left and right sides to the rear. The left front portion 43 is fixed to the bending portion on the left side with a screw. The right front portion 45 is fixed to the bending portion on the right side with a screw.

[0015] The rear member 10b is an integral part formed by a rear portion 47 that forms the rear surface of the housing 10, a left rear portion 48 that forms the rear portion of the left side of the housing 10, and a right rear portion 49 that forms the rear portion of the right side of the housing 10. The rear portion 47, the left rear portion 48, and the right rear portion 49 are formed by bending the rear member 10b. The rear portion 47 has bending portions that bend substantially vertically from the left and right sides to the front. The left rear portion 48 is fixed to the bending portion on the left side with a screw. The right rear portion 49 is fixed to the bending portion on the right side with a screw.

[0016] The left side surface 10g of the housing 10 is formed by fixing the left front portion 43 to the left rear portion 48 with screws. The right side surface 10h of the housing 10 is formed by fixing the right front portion 45 to the right rear portion 49 with screws.

[0017] Semicircular cutouts 10c are provided in each of the left front portion 43, the left rear portion 48, the right front portion 45, and the right rear portion 49. The cutouts 10c become round holes 10d through which the first pipe 15 and the second pipe 16 pass when the front member 10a and the rear member 10b are joined together.

[0018] The housing 10 has an open top and a lower front surface than the other sides, that is, the housing 10 has a box shape with an open top and upper front surface.

[0019] The first pipe 15 is disposed in the upper rear portion of the housing 10. A solenoid valve 17 is disposed in the first pipe 15 (see FIG. 4). The solenoid valve 17 is disposed so as to extend forward from the first pipe 15. A portion of the solenoid valve 17 is disposed so as to be exposed to the outside of the housing 10 from above the front surface of the housing 10. The second pipe 16 is disposed in the front lower portion of the housing 10. A motor-operated valve 18 is disposed in the second pipe 16 (see FIG. 5). The motor-operated valve 18 is disposed at a position that does not overlap with the solenoid valve 17 in a top view, and is disposed so as to extend upward from the second pipe 16. By arranging them in this manner, the first pipe 15, the second pipe 16, the solenoid valve 17, and the motor-operated valve 18 can be accommodated compactly within the housing 10 without interfering with each other.

[0020] The first piping 15 and the solenoid valve 17 are held within the housing 10 by a first mounting stay 19 and a second mounting stay 20. The first mounting stay 19 is attached to the rear surface portion 47, and supports the first piping 15 from below with a surface that extends from the lower portion of the first mounting stay 19 toward the inside of the housing 10. A receiving portion 19a for fixing the second mounting stay 20 extends from the upper end of the first mounting stay 19 toward the inside of the housing 10.

[0021] As shown in Fig. 6, the second mounting stay 20 has an upper surface portion 20a that is approximately parallel to the top plate 12, and a coil support portion 20b that bends approximately vertically downward from the front end of the upper surface portion 20a. The second mounting stay 20 has one end, the coil support portion 20b, fixed to the upper end of the front surface portion 41, and the other end, the upper surface portion 20a, fixed to a receiving portion 19a of the first mounting stay 19. The receiving portion 19a is provided at a position higher than the upper end of the front surface portion 41, and the first mounting stay 19 and the second mounting stay 20 form a hollow, approximately rectangular space. The solenoid valve 17 is disposed in this space.

[0022] The coil support portion 20b has a hole 20c through which the first coil portion 17b of the solenoid valve 17 passes to support the first coil portion 17b. By attaching the first mounting stay 19 and the second mounting stay 20 in this manner, the first piping 15 and the solenoid valve 17 are fixed, and at the same time, the strength of the housing 10 can be improved.

[0023] 4 is a diagram showing the first pipe 15 and the solenoid valve 17. In FIG. 4, the solenoid valve molded heat insulating material 21 is partially omitted so that the solenoid valve 17 can be seen. Inside the housing 10, the solenoid valve 17 and the first pipe 15 are arranged sideways, substantially parallel to a horizontal plane. The solenoid valve 17 includes a solenoid valve body 17a that is attached to the first pipe 15 and opens and closes the interior of the first pipe 15, and a first coil portion 17b (an example of a coil of a first shutoff valve) that is attached to the solenoid valve body 17a and drives the solenoid valve body 17a in response to the supply of power. In this embodiment, the solenoid valve 17 is a pilot-type solenoid valve.

[0024] The solenoid valve main body 17a and the first piping 15 around the solenoid valve 17 are covered with a solenoid valve molded insulation material 21 made of molded polyethylene foam as a heat insulating material. For example, expanded polystyrene may be used as the solenoid valve molded insulation material 21. In this embodiment, the first coil portion 17b is not covered with the solenoid valve molded insulation material 21. This makes it easy to replace the coil.

[0025] Fig. 5 is a diagram showing the second pipe 16 and the motor-operated valve 18. In Fig. 5, part of the motor-operated valve molding insulation material 23 and the motor-operated valve coil insulation material 24 are omitted so that the motor-operated valve 18 can be seen. The motor-operated valve 18 includes a motor-operated valve body 18a that is attached to the second pipe 16 and opens and closes the interior of the second pipe 16, a gear portion 18b that is attached to the motor-operated valve body 18a and drives the motor-operated valve body 18a, and a second coil portion 18c (an example of a coil of a second shutoff valve) that is attached to the gear portion 18b and drives the gear portion 18b in response to the supply of electric power. In this embodiment, the motor-operated valve 18 is an electric ball valve.

[0026] The motor-operated valve body 18a, gear portion 18b, and second piping 16 around the motor-operated valve 18 are covered with motor-operated valve molded insulation material 23 made of molded polyethylene foam. Expanded polystyrene, for example, may be used for the motor-operated valve molded insulation material 23. The second coil portion 18c is covered with motor-operated valve coil insulation material 24 (see FIG. 2).

[0027] 2, 3, and 6, the left front portion 43 and the right front portion 45 are provided with first engagement portions 10e for holding the electrical box 11. The first engagement portions 10e are ribs formed by bending the left front portion 43 and the right front portion 45 toward the inside of the housing 10. The first engagement portions 10e are provided at positions where a predetermined space S1 is created between the top panel 12 and the upper end of the first engagement portions 10e. The predetermined space S1 may be large enough to allow insertion of claw members 11b of the electrical box 11, which will be described later.

[0028] The housing 10 also has a second engagement portion 10f below the first engagement portion 10e. The second engagement portion 10f is the upper end of the front surface portion 41. A space S2 is provided on the front surface of the housing 10 above the front surface portion 41. The predetermined space S2 may be large enough to allow insertion of a claw member 11b of the electrical box 11, which will be described later.

[0029] As shown in FIGS. 3 and 6, the electrical box 11 is box-shaped with an open front and top, and has a notch 11a formed on the rear surface to avoid interference with the first coil portion 17b exposed from the housing 10. Hook-shaped claw members 11b are formed on the left and right sides of the upper end of the rear surface of the electrical box 11. The claw members 11b of the electrical box 11 engage with the first engagement portions 10e, thereby holding the electrical box 11 in the housing 10. In this embodiment, the state in which the first engagement portions 10e engage with the claw members 11b, holding the electrical box 11 in the housing 10, is used as a normal state.

[0030] Top plate 12 is fixed to housing 10 and covers the top surfaces of housing 10 and electrical box 11. In the normal configuration, even with top plate 12 attached, electrical box 11 can be lifted up by the space S1, allowing claw members 11b to disengage from first engagement portions 10e. In other words, space S1 is formed to be large enough to allow electrical box 11 to be removed.

[0031] FIG. 6 is a diagram of the shutoff valve kit 1 with the front plate 13 and the top plate 12 removed and the claw members 11b engaged with the second engagement portions 10f. The shutoff valve kit 1 can hold the electrical box 11 by shifting it downward from the housing 10 by fitting the claw member 11b into the second engagement portion 10f. In the present embodiment, this state is used as the coil replacement mode. In the coil replacement mode, the second engagement portion 10f is provided below the first engagement portion 10e, so the electrical box 11 can be held lower than the position of the electrical box 11 in the normal mode. This creates a space above the electrical box 11, and at the same time, the first coil portion 17b can be exposed from the shutoff valve kit 1.

[0032] Fig. 7 is a top view of the shutoff valve kit 1. Fig. 8 is a top view of the electrical box 11. Fig. 9 is a front view of the electrical box 11.

[0033] A partition plate 25 is provided in the electrical box 11. The partition plate 25 divides the space inside the electrical box 11 into two, a front and a back section. That is, the electrical box 11 is divided by the partition plate 25 into a first space 26 on the rear side and a second space 27 on the front side. A supercapacitor 28 is arranged in the first space 26. A circuit board 29 is arranged on the surface of the partition plate 25 facing the second space 27. The top plate 12 covers the upper part of the first space 26 in addition to the housing 10. The front plate 13 has a front plate front surface portion 13a and a front plate upper surface portion 13b. The front plate front surface portion 13a covers the front of the electrical box 11. The front plate upper surface portion 13b covers the upper part of the second space 27.

[0034] A louver 30 is provided on the top plate 12. As shown in Figs. 3 and 5, the louver 30 is arranged so as to overlap the first coil portion 17b of the solenoid valve 17 in a top view. In other words, the louver 30 is provided from the housing 10 to the first space 26 of the electrical box 11 in a top view. This makes it possible to suppress a temperature rise in the first coil portion 17b.

[0035] Since first coil portion 17b is exposed from housing 10 to electrical box 11, a space for accommodating first coil portion 17b is required on the electrical box 11 side. However, if first coil portion 17b and circuit board 29 are placed together, there is a risk that dust, insects, etc. may enter through louver 30 provided to suppress a temperature rise in first coil portion 17b, which is undesirable.

[0036] In this embodiment, as described above, the partition plate 25 divides the electrical box 11 into a first space 26 in which the first coil portion 17b is accommodated and a second space 27 in which the circuit board 29 is disposed. In addition, a sealer member 13c that fills the gap between the partition plate 25 and the top plate 12 is provided across the entire left-right direction at the rear end of the front plate upper surface portion 13b. The sealer member 13c is disposed so as to seal the gap above the partition plate 25. This prevents insects, dust, and the like that enter the electrical box 11 through the louver 30 provided above the first coil portion 17b from entering the second space 27 in which the circuit board 29 is disposed. In other words, contact between the circuit board 29 and dust and insects can be prevented.

[0037] A metal plate 11c that covers the supercapacitor 28 is arranged in the first space 26. The metal plate 11c has a generally rectangular shape that covers the top surface and the left and right side surfaces of the supercapacitor 28. The front surface of the supercapacitor 28 is covered by the partition plate 25, and the rear surface is covered by the rear surface of the electrical box 11. In other words, the supercapacitor 28 is covered by the partition plate 25, the electrical box 11, and the metal plate 11c, and is arranged in such a way that it is surrounded on all four sides. This also prevents insects from entering the inside of the supercapacitor 28.

[0038] The supercapacitor 28 is disposed in the first space 26 behind the partition plate 25. This allows the frequently accessed board 29 to be disposed in a position that is easily accessible by removing the front plate 13. This improves the maintainability of the electrical box 11.

[0039] 2, the second pipe 16 is arranged in the lower part of the housing 10, and the motor-operated valve 18 is arranged to extend upward. By arranging them in this manner, the space above the shutoff valve kit 1 can be made smaller when replacing the second coil portion 18c compared to when the second pipe 16 is arranged in the upper part of the housing 10.

[0040] Normally, solenoid valves require a constant current to open or close a piping route, but motor-operated valves can maintain an open state even when no current is applied once they are operated. Because solenoid valves require a long current application time, they are likely to be replaced more frequently. Therefore, solenoid valves are preferably located in a location that is easier for workers to access during maintenance than motor-operated valves.

[0041] In this embodiment, solenoid valve 17, which is a solenoid valve, is arranged in a position where it can be replaced without having to remove top plate 12 by being exposed from housing 10 on the electrical box 11 side, and motor-operated valve 18, which is a motor-operated valve, is arranged in a position where it can be replaced from above by removing top plate 12 from housing 10. In other words, since the solenoid valve is arranged in a position where it is easier to access than the motor-operated valve during maintenance, the coil can be replaced efficiently.

[0042] [1-2. Effect]

[0043] The coil replacement for the shutoff valve kit 1 will be explained. Coils have a set service life and must be replaced as necessary after a certain period of time or due to deterioration over time.

[0044] In this embodiment, as described above, in the normal configuration, a space S1 is provided between the housing 10 and the electrical box 11, and therefore the engagement portion of the claw member 11b of the electrical box 11 is changed from the first engagement portion 10e to the second engagement portion 10f, thereby shifting to the coil replacement configuration, without removing the top panel 12. This creates a space around the first coil portion 17b, allowing an operator to access the first coil portion 17b from the electrical box 11 side, thereby facilitating coil replacement.

[0045] [1-3. Effects, etc.] As described above, the shut-off valve kit 1 of this embodiment is a shut-off valve kit 1 in which the solenoid valve 17 connected to the first pipe 15 is housed within the housing 10, and the electrical box 11 is connected to the side of the housing 10 in a manner that allows it to be easily removed. The solenoid valve 17 is disposed within the housing 10 with the side of the housing 10 penetrated so that the first coil portion 17b of the solenoid valve 17 is exposed on the electrical box 11 side, and the electrical box 11 can be removed and accessed from the electrical box 11 side to replace the first coil portion 17b of the solenoid valve 17. This allows the electrical box 11 to be removed and the first coil portion 17b of the solenoid valve to be accessed from the side of the electrical box 11 connected to the side of the housing 10, so that the first coil portion 17b of the solenoid valve can be easily replaced without removing the top surface of the housing 10, eliminating the need for service space above the housing 10 for replacing the coil of the solenoid valve 17.

[0046] The electrical box 11 is supported on the side surface of the housing 10 so as to be freely movable in the vertical direction, and when the electrical box 11 is lowered, the first coil part 17b of the solenoid valve 17 can be accessed from the electrical box 11 side and replaced. This allows access to the first coil portion 17b of the solenoid valve 17 without completely removing the electrical box 11 from the housing 10, so that the first coil portion 17b of the solenoid valve 17 can be easily replaced even in a small space.

[0047] The electrical box 11 is provided with a claw member that engages with a first engagement portion 10e on the side of the housing 10 when the electrical box 11 is permanently fixed to the housing 10, and the claw member 11b is engaged with a second engagement portion 10f located below the first engagement portion 10e, so that with the electrical box 11 temporarily fixed, the first coil portion 17b of the solenoid valve 17 can be replaced by accessing it from the electrical box 11 side. This allows the electrical box 11 to be temporarily fixed by lowering the engagement position of the claw member 11b from the first engagement portion 10e to the second engagement portion 10f located below the first engagement portion 10e, making it easy to access the first coil portion 17b of the solenoid valve 17 without completely removing the electrical box 11 from the housing 10.

[0048] The device is provided with a top plate 12 that serves as both the top surface of the housing 10 and the top surface of the electrical box 11, and the first coil portion 17b of the solenoid valve 17 is positioned so as to straddle the housing 10 and the electrical box 11, and the top plate 12 is provided with a louver 30 at a position that overlaps with the first coil portion 17b of the solenoid valve 17 in a plan view. With this, the first coil portion 17b of the solenoid valve 17 is positioned so as to straddle the housing 10 and the electrical box 11, thereby making the shut-off valve kit 1 compact, and by using the top plate 12, which also serves as the top surface of the housing 10 and the top surface of the electrical box 11, and providing a grille 30 at a position on the top plate 12 that overlaps in a planar view with the first coil portion 17b of the solenoid valve, whose temperature rises, the temperature rise of the first coil portion 17b of the solenoid valve 17 can be suppressed with a single component.

[0049] The electrical box 11 has a first space 26 adjacent to the housing 10 and a second space 27 separated from the first space 26 by a partition plate extending from the bottom of the electrical box 11 to near the top plate 12, and the partition plate 25 is positioned so that the louver 30 does not overlap with the second space 27 in a plan view, and a circuit board 29 is placed in the second space 27. According to this, the louver 30 can suppress a rise in temperature of the first coil portion 17b of the solenoid valve 17, while also suppressing dust and the like from entering the substrate 29 through the louver 30.

[0050] A supercapacitor 28 is disposed in the first space 26 of the electrical box 11 . This prevents dust and the like from entering the circuit board 29 through the louver 30, and by arranging the supercapacitor 28 in the first space 26, the space in the electrical box 11 can be used effectively.

[0051] The electric valve 18 is provided with an electric valve 18 connected to a second pipe 16 separate from the first pipe 15, the electric valve 18 having a longer service life than the solenoid valve 17, the housing 10 is provided with a top plate 12, the second pipe 16 is positioned below the first pipe 15, the solenoid valve 17 is fixed in a state where it protrudes laterally from the first pipe 15, and the electric valve 18 is fixed in a state where it protrudes upward from the second pipe 16 in a position where it does not overlap with the solenoid valve in a plan view, and the electric valve 18 can be accessed from above the housing 10 by removing the top plate 12 and replacing the second coil portion 18c of the electric valve 18. According to this, it is expected that the motor-operated valve 18, which has a longer service life than the solenoid valve 17, will normally need to be replaced less frequently than the solenoid valve 17. With the above configuration, the space above for replacing the motor-operated valve of the second pipe 16, which is located below the first pipe 15, can be reduced, and the shutoff valve kit 1 can be made smaller.

[0052] (Other embodiments) As described above, the above-mentioned first embodiment has been described as an example disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. Furthermore, it is also possible to combine the components described in the above-mentioned first embodiment to create new embodiments. Therefore, other embodiments will be exemplified below.

[0053] The above-mentioned solenoid valve 17 and motor-operated valve 18 have been described with respect to their arrangement, taking the example of their service life based on the time they are energized. However, service life is not determined solely by the time they are energized. For example, it is determined taking into consideration factors such as consumables, the operating environment, mechanical life, and electrical life. In other words, the arrangement of the solenoid valve 17 and motor-operated valve 18 may take into consideration the service life based on a single factor, or may take into consideration the service life based on multiple factors. In the above-described embodiment, an example has been described in which the service life of the solenoid valve is longer than the service life of the motor-operated valve. Therefore, if the service life of the motor-operated valve is longer than the service life of the solenoid valve, the first shutoff valve may be an electric valve and the second shutoff valve may be an solenoid valve.

[0054] It should be noted that the above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, etc. may be made within the scope of the claims or their equivalents.

[0055] (Addendum) The above description of the embodiments discloses the following techniques.

[0056] (Technology 1) A shut-off valve kit in which a first shut-off valve connected to a pipe is housed in a housing, and an electrical box is connected to the side of the housing in a manner that allows it to be easily removed, wherein the first shut-off valve is disposed in the housing with the side of the housing penetrated to expose the coil of the first shut-off valve on the electrical box side, and the electrical box can be removed and accessed from the electrical box side to replace the coil of the first shut-off valve. This allows the electrical box to be removed and the coil of the first shut-off valve to be accessed from the electrical box side connected to the side of the housing, so the coil of the first shut-off valve can be easily replaced without removing the top surface of the housing, eliminating the need for service space above the housing for replacing the coil of the first shut-off valve.

[0057] (Technology 2) The electrical box is supported on the side surface of the housing so as to be freely movable in the vertical direction, and when the electrical box is lowered, the coil of the first shut-off valve can be replaced by accessing it from the electrical box side. This is a shut-off valve kit as described in Technology 1. This allows access to the coil of the first shutoff valve without completely removing the electrical box from the housing, making it possible to easily replace the coil of the first shutoff valve even in a small space.

[0058] (Technology 3) The electrical box is provided with a claw member that engages with a first engagement portion on the side surface of the housing when the electrical box is permanently fixed to the housing, and the claw member is engaged with a second engagement portion that is positioned lower than the first engagement portion, so that with the electrical box temporarily fixed, the coil of the first shut-off valve can be replaced by accessing it from the electrical box side. This is a shut-off valve kit as described in Technology 1 or 2. This allows the electrical box to be temporarily fixed by lowering the engagement position of the claw member from the first engagement portion to the second engagement portion located below the first engagement portion, making it easy to access the coil of the first shut-off valve without completely removing the electrical box from the housing.

[0059] (Technology 4) A shutoff valve kit according to any one of Technologies 1 to 3, comprising a top plate that serves as both the top surface of the housing and the top surface of the electrical box, the coil of the first shutoff valve being positioned across the housing and the electrical box, and the top plate comprising a louver in a position that overlaps with the coil of the first shutoff valve in a plan view. With this, the coil of the first shut-off valve is positioned so as to straddle the housing and the electrical box, thereby making the shut-off valve kit compact, and by using a top plate that serves as both the top surface of the housing and the top surface of the electrical box and providing a grill at a position on the top plate that overlaps in plan view with the coil of the first shut-off valve, whose temperature rises, the temperature rise of the coil of the first shut-off valve can be suppressed with a single component.

[0060] (Technology 5) The electrical box includes a first space adjacent to the housing and a second space separated from the first space by a partition plate extending from the bottom of the electrical box to the vicinity of the top plate, the partition plate being positioned so that the louver does not overlap with the second space in a plan view, and a circuit board is placed in the second space, in a shut-off valve kit according to Technology 4. According to this, the louver can suppress a rise in temperature of the coil of the first shutoff valve, and can also suppress dust and the like from entering the board through the louver.

[0061] (Technology 6) The shut-off valve kit according to Technology 5, wherein a supercapacitor is disposed in the first space. This prevents dust and other particles from entering the circuit board through the louver, while arranging the supercapacitor in the first space allows for effective use of the space in the electrical box.

[0062] (Technology 7) A shut-off valve kit according to any one of technologies 1 to 6, comprising a second shut-off valve connected to a second pipe separate from the first pipe, the second shut-off valve having a longer service life than the first shut-off valve, the housing having a top plate, the second pipe being located below the first pipe, the first shut-off valve being fixed in a state where it protrudes laterally from the first pipe, and the second shut-off valve being fixed in a state where it protrudes upward from the second pipe at a position where it does not overlap with the first shut-off valve in a plan view, and the second shut-off valve is accessible from above the housing by removing the top plate, allowing the coil of the second shut-off valve to be replaced. According to this, it is expected that the second shutoff valve, which has a longer service life than the first shutoff valve, will normally need to be replaced less frequently than the first shutoff valve. With the above configuration, it is possible to reduce the space above for replacing the motor-operated valve of the second pipe located below the first pipe, and to make the shutoff valve kit more compact. [Industrial Applicability]

[0063] As described above, the shutoff valve kit according to the present invention can be used in the indoor unit of an air conditioner, etc. [Explanation of symbols]
