[0008] (Findings that formed the basis of this disclosure) At the time the inventors came up with the idea for the present disclosure, there was a technology in which the solenoid valves and motor-operated valves provided in the shutoff valve kits each had a coil that drove the valve body. However, the inventors discovered that the conventional technology had a problem in that condensation occurred in the solenoid valves and motor-operated valves, and in order to solve this problem, they came up with the subject matter of the present disclosure. Therefore, the present disclosure provides a shutoff valve kit that can suppress condensation on solenoid valves and motor-operated valves.
[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 with a substantially rectangular parallelepiped appearance. The shutoff valve kit 1 includes a housing 10 that houses a solenoid valve 17 and an electric valve 18 (described later), an electrical box 11 in which a circuit board 29 and a supercapacitor 28 (described later) 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] 2, 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] Fig. 4 is a perspective view of the first pipe 15 and the solenoid valve covering molded product 21a, and is a diagram showing the first pipe 15 and the solenoid valve 17. In Fig. 4, the solenoid valve covering molded product 21a on one side is omitted so that the solenoid valve 17 can be seen. Fig. 5 is a perspective view of the first pipe 15 and the solenoid valve molded insulating material 21. 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 attached to the first pipe 15 to open and close the interior of the first pipe 15, and a first coil portion 17b attached to the solenoid valve body 17a to drive 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 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 for the solenoid valve molded insulation material 21. The solenoid valve molded insulation material 21 is composed of a pair of solenoid valve covering molded parts 21a.
[0025] In this embodiment, the first coil portion 17b is not covered with the electromagnetic valve molded heat insulating material 21. This allows for easy coil replacement.
[0026] Fig. 6 is a diagram showing the second piping 16 and the motor-operated valve covering molded part 23a. In Fig. 6, the motor-operated valve covering molded part 23a on one side and the motor-operated valve coil insulation material 24 are omitted so that the motor-operated valve 18 can be seen. Figs. 7 and 8 are perspective views of the second piping 16 and the motor-operated valve molded insulation material 23. Fig. 8 is a schematic diagram of the motor-operated valve with the motor-operated valve coil insulation material 24 removed. 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 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.
[0027] The motor-operated valve body 18a, gear portion 18b, and second piping 16 around the motor-operated valve 18 are covered with a motor-operated valve molded insulation material 23 made of molded polyethylene foam as a heat insulating material. For example, expanded polystyrene may be used for the motor-operated valve molded insulation material 23. The motor-operated valve molded insulation material 23 is composed of a pair of motor-operated valve covering molded parts 23a. The second coil portion 18c is covered with an electric valve coil heat insulating material 24 (see FIG. 2).
[0028] As shown in FIG. 4, the first pipe 15 includes a bottom pipe 15a connected to the bottom of the solenoid valve body 17a and a side pipe 15b perpendicular to the bottom pipe 15a and connected to the side of the solenoid valve body 17a. The bottom pipe 15a and the side pipe 15b are arranged perpendicular to each other on the same plane. The bottom pipe 15a and the side pipe 15b are also curved on the same plane and connected to the solenoid valve body 17a. One end of the bottom pipe 15a is connected to the bottom of the solenoid valve body 17a, and the other end extends outside the housing 10. One end of the side pipe 15b is connected to the right side of the solenoid valve body 17a, and the other end extends outside the housing 10. Arranging the pipes 15 on the same plane makes it easy to cover them with a pair of solenoid valve covering molded products 21a.
[0029] The solenoid valve body 17a and portions of the bottom pipe 15a and side pipe 15b are covered by a pair of solenoid valve covering molded parts 21a. The pair of solenoid valve covering molded parts 21a are formed by vacuum-forming a sheet of polyethylene foam insulation material to fit the shapes of the solenoid valve body 17a, bottom pipe 15a, and side pipe 15b. Specifically, the resin used as the molding material is heated and plasticized, then placed on a mold, and vacuum suction is applied from inside the mold to form and cool the material. The solidified resin is then demolded to obtain the solenoid valve covering molded parts 21a with the desired shape. This minimizes gaps between the solenoid valve body 17a, bottom pipe 15a, and side pipe 15b.
[0030] The pair of solenoid valve covering molded parts 21a each have adhesive tape 36 attached to the end of the mating surface. This allows the pair of solenoid valve covering molded parts 21a to adhere to each other. The solenoid valve covering molded parts 21a also have a plurality of round holes 38 formed inward from the adhesive tape 36 attached to the end. The round holes 38 are formed so that the holes 38 mate with each other when the pair of solenoid valve covering molded parts 21a are mated.
[0031] As shown in Fig. 5, a band 37 passes through round holes 38 formed in a tightly fitted state and fastens the pair of solenoid valve covering molded parts 21a. That is, the solenoid valve molded insulating material 21 is formed by fixing the pair of solenoid valve covering molded parts 21a with adhesive tape 36 and band 37. By fitting the pair of solenoid valve covering molded parts 21a with adhesive tape 36 and band 37 in this way, air is prevented from entering the solenoid valve molded insulating material 21, preventing condensation.
[0032] The first coil portion 17b may need to be replaced periodically, and since it generates heat when in operation, no insulation is provided for the first coil portion 17b. In such a case, a gap may form between the solenoid valve molded insulation material 21 and the first coil portion 17b, which may allow air to enter the solenoid valve molded insulation material 21. For this reason, a sealing member 22 is provided in the gap between the solenoid valve molded insulation material 21 and the first coil portion 17b to prevent air from entering the solenoid valve molded insulation material 21 from the first coil portion 17b side. This also prevents condensation from occurring in the first piping 15 and the solenoid valve 17. The sealing member 22 is flush with the solenoid valve and is larger than the bottom surface of the first coil portion 17b, and is sandwiched and tightly attached between the top surface of the solenoid valve molded insulator 21 and the bottom surface of the first coil portion 17b. Although the bottom surface of the first coil portion 17b is larger than the top surface of the solenoid valve molded insulator 21, the sealing member 22 allows it to be more stably fixed to the top surface of the solenoid valve molded insulator 21.
[0033] As shown in Figure 6, the second pipe 16 is connected to the motor-operated valve main body 18a. The second pipe 16 has a left pipe 16a and a right pipe 16b. The left pipe 16a, the right pipe 16b, and the motor-operated valve main body 18a are arranged in the same straight line. One end of the left pipe 16a is connected to the left side of the motor-operated valve main body 18a, and the other end extends outside the housing 10. One end of the right pipe 16b is connected to the right side of the motor-operated valve 18a, and the other end extends outside the housing 10. By forming the pipe in this way without any bends, it becomes easy to cover it with a pair of motor-operated valve covering molded products 23a.
[0034] The motor-operated valve body 18a, the gear portion 18b, and portions of the left and right pipes 16a and 16b are covered by a pair of motor-operated valve covering molded parts 23a. The motor-operated valve covering molded parts 23a are formed by vacuum-molding a sheet of polyethylene foam insulation material to fit the shapes of the solenoid valve body 17a, the gear portion 18b, the left and right pipes 16a and 16b. Specifically, the resin used as the molding material is heated and plasticized, then placed on a mold, and vacuum suction is applied from the inside of the mold to form and cool the material. The solidified resin is then demolded to obtain the solenoid valve covering molded part 21a, which fits the desired shape. This allows the solenoid valve body 17a, the left and right pipes 16a and 16b to be covered with minimal gaps.
[0035] The pair of motor-operated valve covering molded parts 23a are provided with adhesive tape 36 at the end of the mating surface, so that the pair of motor-operated valve covering molded parts 23a are in close contact with each other to form the motor-operated valve molded insulation material 23.
[0036] As shown in Fig. 7, the upper portions of the pair of motor-operated valve covering molded parts 23a are fastened together with a band 37. That is, the motor-operated valve molded insulation material 23 is formed by fixing the pair of motor-operated valve covering molded parts 23a with adhesive tape 36 and band 37. By joining the pair of motor-operated valve covering molded parts 23a together with adhesive tape 36 and band 37, air is prevented from entering the motor-operated valve molded insulation material 23, preventing condensation.
[0037] The upper surface of the motor-operated valve molded insulation 23 is in close contact with the motor-operated valve coil insulation 24. This prevents air from entering through gaps in the motor-operated valve molded insulation 23. This prevents condensation from forming in the second piping 16 and the motor-operated valve 18. Furthermore, because the motor-operated valve coil insulation 24 is formed separately from the motor-operated valve molded insulation 23, the second coil portion 18c can be efficiently replaced when performing maintenance on the shutoff valve kit 1.
[0038] 8, a sealing member 122 is provided between the motor-operated valve molded insulation 23 and the motor-operated valve coil insulation 24. The upper surface of the motor-operated valve molded insulation 23 is flush with the surface. The lower surface of the motor-operated valve coil insulation 24 is also flush with the surface. The sealing member 122 is provided between the upper surface of the motor-operated valve molded insulation 23 and the lower surface of the motor-operated valve coil insulation 24, and seals the entire upper surface of the motor-operated valve molded insulation 23 and the entire lower surface of the motor-operated valve coil insulation 24. The sealing member 122 is made of a material that is softer than the material used for the motor-operated valve molding insulation 23 and the motor-operated valve coil insulation 24. In this embodiment, the motor-operated valve molding insulation 23 and the motor-operated valve coil insulation 24 are made of polyethylene foam. The motor-operated valve coil insulation 24 may be made of, for example, expanded polystyrene. The sealing member 122 is made of open-cell polyethylene. For example, it is conceivable that the motor-operated valve molded insulation 23 and the motor-operated valve coil insulation 24, which are hard insulation materials, may interfere with the wiring extending from the second coil portion 18c, creating a gap. In this embodiment, by providing a sealing member 122 that is softer than the motor-operated valve molded insulation 23 and the motor-operated valve coil insulation 24 between the upper surface of the motor-operated valve molded insulation 23 and the lower surface of the motor-operated valve coil insulation 24, the sealing member 122 can deform to fit the shape of the wiring, thereby preventing a gap from forming between the motor-operated valve molded insulation 23 and the motor-operated valve coil insulation 24. This makes it possible to prevent condensation on the motor-operated valve molded insulation material 23 and the motor-operated valve coil insulation material 24 even when wiring is extended to the motor-operated valve molded insulation material 23 and the motor-operated valve coil insulation material 24.
[0039] [1-2. Effect]
[0040] Normally, condensation occurs in shutoff valve kits due to the temperature difference between the outside air and the piping. The solenoid valve body 17a and the first pipe 15 are covered with a solenoid valve molded insulation material 21, and the gap between the solenoid valve molded insulation material 21 and the first coil portion 17b is sealed with a sealing member 22. This prevents the solenoid valve body 17a and the first pipe 15 from coming into contact with the outside air, thereby preventing condensation inside the shutoff valve kit 1.
[0041] Furthermore, the motor-operated valve body 18a, gear portion 18b, and second piping 16 are covered with motor-operated valve molded insulation material 23, and the upper surface of the motor-operated valve molded insulation material 23 is sealed by being in close contact with the lower surface of the motor-operated valve coil insulation material 24 that covers the second coil portion 18c via a sealing member 122. This prevents the motor-operated valve 18 and second piping 16 from coming into contact with the outside air, thereby preventing condensation within the shutoff valve kit 1.
[0042] [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 at least one of the solenoid valve 17 and the electric valve 18 is housed within the housing 10, and the electrical box 11 is removably connected to the side of the housing 10, and within the housing 10, the solenoid valve main body 17a and the electric valve main body 18a are covered with the solenoid valve molded insulation material 21 or the electric valve molded insulation material 23, with the coils being replaceable. This effectively prevents condensation on the solenoid valve body 17a and the motor-operated valve body 18a, while allowing the coil to be easily replaced.
[0043] The solenoid valve 17 is a pilot-type solenoid valve, and the solenoid valve body 17a and the first piping 15 connected to the solenoid valve body 17a are covered with solenoid valve molded insulation material 21 with the first coil portion 17b exposed to the outside. This effectively prevents condensation on the solenoid valve body 17a and the first pipe 15 connected to the solenoid valve body 17a, and also stably fixes the solenoid valve body 17a, while allowing the coil to be easily replaced.
[0044] The solenoid valve molded insulation material 21 comprises a pair of solenoid valve covering molded parts 21a made of polyethylene foam, and the solenoid valve body 17a and the first pipe 15 are covered by the pair of solenoid valve covering molded parts 21a, sandwiching them from both sides, the mating surfaces of the pair of solenoid valve covering molded parts 21a are adhered together with adhesive tape 36, and the pair of solenoid valve covering molded parts 21a are bound together with a band 37. This effectively prevents condensation on the solenoid valve body 17a and the first pipe 15 connected to the solenoid valve body 17a, and also allows the solenoid valve body 17a to be stably fixed.
[0045] The electromagnetic valve molded heat insulator 21 includes a sealing member 22 that seals the exposed portion of the first coil portion 17b. As a result, since the first coil portion 17b becomes hot due to heat generation, even if it is not covered with the solenoid valve molded insulation material 21, it is possible to prevent air from entering the inside of the solenoid valve molded insulation material 21 from the mounting portion of the first coil portion 17b.
[0046] The piping comprises a bottom piping 15a connected to the bottom of the solenoid valve body 17a, and a side piping 15b perpendicular to the bottom piping 15a and connected to the side of the solenoid valve body 17a, and the bottom piping 15a and the side piping 15b are arranged in the same plane. According to this, by forming the shape with a small bend in the depth direction, the solenoid valve body 17a and the piping connected to the solenoid valve body 17a can be easily covered with the pair of solenoid valve covering molded parts 21a.
[0047] The electric valve 18 is an electric ball valve having a gear portion 18b that drives the electric valve main body 18a, and with the second coil portion 18c exposed to the outside, the electric valve main body 18a and the gear portion 18b of the electric valve 18 are covered by an electric valve molded insulation material 23, and the second coil portion 18c exposed to the outside of the electric valve molded insulation material 23 is covered by an electric valve coil insulation material 24, which serves as a sealing member that seals the top of the electric valve molded insulation material 23. This prevents air from entering the motor-operated valve molding insulation material 23 and the motor-operated valve coil insulation material 24, and prevents condensation on the motor-operated valve 18 and the piping connected to the motor-operated valve 18.
[0048] The electric valve molded insulation material 23 comprises a pair of electric valve covering molded parts 23a made of polyethylene foam, and the electric valve body 18a and the gear part 18b are covered by the pair of electric valve covering molded parts 23a, sandwiching them from both sides, and the mating surfaces of the pair of electric valve covering molded parts 23a are sealed with adhesive tape 36, and the pair of electric valve covering molded parts 23a are bound together with a band 37. This effectively prevents condensation on the motor-operated valve body 18a and the gear portion 18b, and also allows the motor-operated valve body 18a and the gear portion 18b to be stably fixed.
[0049] 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.
[0050] (Addendum) The above description of the embodiments discloses the following techniques.
[0051] (Technology 1) A shut-off valve kit in which at least one of a solenoid valve and an electric valve is housed in a housing, and an electrical equipment box is removably connected to the side of the housing, and within the housing, the solenoid valve body and the electric valve body are covered with molded insulation material in a state in which the coil is replaceable.
