Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of air conditioner outdoor units, and more specifically, to a shut-off valve fixing structure and a multi-split air conditioner outdoor unit. Background Technology
[0002] In modern building design and air conditioning system configuration, multi-split air conditioning units (also known as VRF systems) have become an important component of central air conditioning systems due to their advantages such as high efficiency, energy saving, flexible control, and high space utilization. VRF units connect multiple indoor units to a single outdoor unit, achieving unified control of the indoor environment and meeting individual needs. However, with the increasing compactness and diversity of building designs, the spatial constraints of air conditioning installation locations are becoming increasingly prominent, especially in high-rise buildings and small-sized residences, where the installation and maintenance of outdoor units face numerous challenges.
[0003] Currently, the design of multi-split air conditioner outdoor units generally adopts a layout where the shut-off valve connecting the indoor and outdoor units' air inlet and outlet is located on the right-side valve plate, protruding from the exterior of the machine. This design meets basic operation and maintenance needs under standard installation conditions. However, in practical applications, due to the often compact space planning of building designs for air conditioner installations, and the right side frequently being obstructed by railings, walls, or other structures, the operating space is limited. This makes it difficult for workers to access the shut-off valve, increasing the difficulty of operation and potentially leading to equipment damage or safety accidents due to improper operation. Furthermore, the narrow operating space restricts the use of maintenance tools, prolongs maintenance time, and reduces work efficiency. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology in that it is inconvenient to maintain the shut-off valve, and to provide a shut-off valve fixing structure and a multi-split air conditioner outdoor unit, which facilitates the maintenance of the shut-off valve.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A gate valve fixing structure is provided, including a first mounting plate, a connecting plate, and a first fixing plate, all of which are vertically arranged. The first mounting plate and the first fixing plate are respectively connected to the two ends of the connecting plate in the horizontal direction. The first mounting plate and the connecting plate have an included angle. The first mounting plate is provided with a plurality of mounting grooves in the vertical direction.
[0007] This utility model discloses a gate valve fixing structure. A first mounting plate has multiple mounting grooves along the vertical direction, allowing multiple gate valves to be installed vertically in different grooves. This facilitates maintenance of each gate valve. The first mounting plate and the connecting plate are angled together, and the first mounting plate and the first fixing plate are connected to the horizontal ends of the connecting plate, meaning they are not on the same plane. This provides ample space for the nuts on the gate valves, facilitating easy installation and removal of the nuts using tools and ensuring that the gate valve nuts can be easily loosened. By arranging multiple gate valves vertically and positioning the first mounting plate and the first fixing plate on different planes, it is easy to install and remove the nuts of multiple gate valves using tools, ensuring that all gate valve nuts can be easily loosened, thus facilitating gate valve maintenance and improving maintenance efficiency.
[0008] Furthermore, the first mounting plate is perpendicular to the connecting plate, and the first mounting plate is parallel to the first fixing plate. The parallel arrangement of the first mounting plate and the first fixing plate ensures that the distance between them is equal to the length of the connecting plate. By changing the length of the connecting plate, the distance between the first mounting plate and the first fixing plate can be adjusted according to actual needs, providing ample space for tool operation.
[0009] Furthermore, there are two of each of the first fixing plate and the connecting plate. Both connecting plates are connected to the first mounting plate, and the two first fixing plates are respectively connected to the two connecting plates. Multiple mounting slots are located between the two first fixing plates. This arrangement of the mounting slots and the first fixing plates avoids gaps, ensuring a stable connection between the shut-off valve fixing structure and the air conditioner outdoor unit while also providing ample space for tool operation.
[0010] Furthermore, the mounting groove is a C-shaped groove, with mounting holes on both sides. During installation, the shut-off valve is placed into the C-shaped groove, and then bolts are passed through the mounting holes to fix the shut-off valve to the shut-off valve fixing structure. This achieves a stable connection between the shut-off valve and the valve plate while facilitating quick assembly and disassembly.
[0011] Furthermore, a reinforcing bending plate is provided between each of the two adjacent C-shaped grooves. The reinforcing bending plate is disposed on the first mounting plate, and the reinforcing bending plate forms an angle with the first mounting plate. By providing the reinforcing bending plate, the strength of the C-shaped groove of the first mounting plate is enhanced, preventing deformation of the shut-off valve fixing structure after the shut-off valve is installed.
[0012] Furthermore, it also includes a horizontally arranged second fixing plate, which is disposed on the first mounting plate, and the second fixing plate and the connecting plate are respectively located on adjacent sides of the first mounting plate. By setting the second fixing plate, the shut-off valve fixing structure is further stably installed on the air conditioner outdoor unit.
[0013] Furthermore, it also includes a second mounting plate, which is disposed on the first mounting plate and forms an angle with the first mounting plate. The second mounting plate and the connecting plate are respectively located on opposite sides of the first mounting plate. By providing the second mounting plate, it is easier to adapt to the fixing requirements of the throttling electronic expansion valve.
[0014] This utility model also provides a multi-split air conditioner outdoor unit, including a housing, an inspection plate, and the aforementioned shut-off valve fixing structure. The housing has an inspection port, the inspection plate is detachably connected to the housing, the inspection plate is located at the inspection port, the shut-off valve fixing structure is located at the inspection port, and the first fixing plate is connected to the housing.
[0015] This utility model of a multi-split air conditioner outdoor unit has a shut-off valve fixed structure installed inside the housing, which not only maintains the overall aesthetics of the housing but also effectively avoids accidental damage to the shut-off valve during transportation. At the same time, an inspection port is opened on the housing, so when the shut-off valve needs to be repaired, the inspection plate can be removed to expose the inspection port, and the shut-off valve can be repaired from the inspection port.
[0016] Furthermore, the housing includes a bottom plate, a front panel, a first side panel, a rear panel, a second side panel, and a top cover. The front panel, first side panel, rear panel, and second side panel are connected sequentially. Both ends of the front panel, first side panel, rear panel, and second side panel are respectively located on the bottom plate and the top cover. The first fixing plate is connected to the first side panel. The inspection port is located on the front panel, and the inspection port is detachably connected to the front panel. Because the space planning of air conditioning units is often quite compact, the sides of the outdoor unit are often obstructed by railings, walls, or other structures, resulting in limited operating space and making it difficult for staff to access the shut-off valve. By placing the inspection port on the front panel, staff can directly repair the shut-off valve from the front of the outdoor unit. This not only significantly reduces the difficulty of installation and maintenance but also provides ample operating space for operators, effectively avoiding the inconvenience caused by space constraints in traditional operations. This significantly improves the efficiency and safety of multi-split air conditioner shut-off valve installation and maintenance.
[0017] Furthermore, the access panel is provided with knockout holes. By providing knockout holes, the refrigerant pipe path is avoided, preventing interference with the refrigerant pipe. At the same time, the access panel can be removed through the knockout holes when disassembling it.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. The present invention relates to a gate valve fixing structure and a multi-split air conditioner outdoor unit. By arranging multiple gate valves vertically and positioning the first mounting plate and the first fixing plate on different planes, it is convenient to use tools to install and remove the nuts of multiple gate valves, ensuring that the nuts of multiple gate valves can be easily loosened, facilitating the maintenance of the gate valves and improving maintenance efficiency.
[0020] 2. The present invention relates to a stop valve fixing structure and a multi-split air conditioner outdoor unit. By installing the stop valve fixing structure inside the housing, the overall aesthetics of the housing are maintained, and accidental damage to the stop valve during transportation is effectively avoided. At the same time, an inspection port is opened on the housing. When the stop valve needs to be repaired, the inspection plate is removed to expose the inspection port, and the stop valve can be repaired from the inspection port.
[0021] 3. The gate valve fixing structure and multi-split air conditioner outdoor unit of this utility model, by opening the inspection port on the front panel, makes it convenient for staff to directly repair the gate valve from the front side of the air conditioner outdoor unit. This not only greatly reduces the difficulty of operation during installation and maintenance, but also provides ample operating space for operators, effectively avoiding the inconvenience caused by space constraints in traditional operation, and significantly improving the work efficiency and safety of gate valve installation and maintenance in multi-split units.

[0029] Example 1
[0030] This embodiment is the first embodiment of the gate valve fixing structure, such as... Figure 1 and Figure 2 As shown, the device includes a first mounting plate 110, a connecting plate 120, and a first fixing plate 130, all of which are vertically arranged. The first mounting plate 110 and the first fixing plate 130 are respectively connected to the two ends of the connecting plate 120 in the horizontal direction. That is, the first mounting plate 110 and the first fixing plate 130 are respectively connected to the left and right ends of the connecting plate 120. The first mounting plate 110 and the connecting plate 120 have an included angle, that is, the first mounting plate 110 and the first fixing plate 130 are not on the same plane. The first mounting plate 110 is provided with a plurality of mounting grooves 111 in the vertical direction. The mounting grooves 111 are used to install the shut-off valve.
[0031] The first mounting plate 110 is perpendicular to the connecting plate 120, and the first mounting plate 110 is parallel to the first fixing plate 130. The parallel arrangement of the first mounting plate 110 and the first fixing plate 130 ensures that the distance between them is equal to the length of the connecting plate 120. By changing the length of the connecting plate 120, the distance between the first mounting plate 110 and the first fixing plate 130 can be adjusted according to actual needs, providing ample space for tool operation.
[0032] Two first fixing plates 130 and two connecting plates 120 are provided. Both connecting plates 120 are connected to the first mounting plate 110. The two first fixing plates 130 are respectively connected to the two connecting plates 120. Multiple mounting slots 111 are located between the two first fixing plates 130. Figure 1 As shown, the two first fixing plates 130 are located at the upper and lower ends of the first mounting plate 110, respectively. The mounting groove 111 is separated from the first fixing plate 130, which not only allows the shut-off valve fixing structure to be stably connected to the air conditioner outdoor unit, but also provides sufficient space for tool operation.
[0033] The mounting groove 111 is a C-shaped groove, with mounting holes 112 on both sides of the C-shaped groove. During installation, the gate valve is placed into the C-shaped groove, and then bolts are passed through the mounting holes 112 to fix the gate valve to the gate valve fixing structure. This achieves a stable connection between the gate valve and the valve plate, and also facilitates quick assembly and disassembly.
[0034] A reinforcing bending plate 113 is provided between each two adjacent C-shaped grooves. The reinforcing bending plate 113 is provided on the first mounting plate 110, and the reinforcing bending plate 113 and the first mounting plate 110 have an included angle. In this embodiment, the included angle is a right angle. By providing the reinforcing bending plate 113, the strength of the C-shaped groove of the first mounting plate 110 is strengthened, so as to avoid deformation of the gate valve fixing structure after the gate valve is installed.
[0035] In this embodiment, the shut-off valve fixing structure 100 is a single piece of sheet metal bent into shape.
[0036] The working principle of the shut-off valve fixing structure 100 in this embodiment is as follows:
[0037] The first mounting plate 110 has multiple mounting slots 111 along the vertical direction, allowing multiple gate valves to be installed vertically in different mounting slots 111. This facilitates maintenance of each gate valve. The first mounting plate 110 and the connecting plate 120 are at an angle. The first mounting plate 110 and the first fixing plate 130 are connected to the two ends of the connecting plate 120 in the horizontal direction, respectively. This means the first mounting plate 110 and the first fixing plate 130 are not on the same plane, providing ample space for the nuts on the gate valves. This facilitates the installation and removal of the nuts using tools, ensuring that the gate valve nuts can be easily loosened. By arranging multiple gate valves vertically and positioning the first mounting plate and the first fixing plate 130 on different planes, it is easy to install and remove the nuts of multiple gate valves using tools, ensuring that all gate valve nuts can be easily loosened, thus facilitating maintenance and improving maintenance efficiency.
[0038] Example 2
[0039] This embodiment is a second embodiment of a gate valve fixing structure. This embodiment is similar to the first embodiment, except that, as shown in the example... Figure 1 As shown, it also includes a horizontally arranged second fixing plate 140, which is disposed on the first mounting plate 110. The second fixing plate 140 and the connecting plate 120 are respectively located on adjacent sides of the first mounting plate 110. In this embodiment, as shown... Figure 1 As shown, the first fixing plate 130 is located on the right side of the first mounting plate 110, and the second fixing plate 140 is located at the bottom of the first mounting plate 110. Both the first fixing plate 130 and the second fixing plate 140 are provided with bolt holes for installation and fixing. By setting the second fixing plate 140, the shut-off valve fixing structure is further stably installed on the outdoor unit of the air conditioner.
[0040] It also includes a second mounting plate 150, which is disposed on the first mounting plate 110. The second mounting plate 150 and the first mounting plate 110 form an angle. The second mounting plate 150 and the connecting plate 120 are respectively located on both sides of the first mounting plate 110, such as... Figure 1 As shown, the connecting plate 120 is bent backward, and the second mounting plate 150 is bent forward. By setting the second mounting plate 150, it is easy to adapt to the fixing requirements of the throttling electronic expansion valve, so that the throttling electronic expansion valve can be installed in front of the shut-off valve, and it is also convenient to maintain the throttling electronic expansion valve.
[0041] Example 3
[0042] This embodiment is a first embodiment of a multi-split air conditioner outdoor unit, such as... Figure 3As shown, the device includes a housing 200, a maintenance plate 300, and a shut-off valve fixing structure 100 provided in Embodiment 1 or Embodiment 2. The housing 200 has a maintenance port 221. The maintenance plate 300 is detachably connected to the housing 200. In this embodiment, bolts are used for connection. The maintenance plate 300 is located at the maintenance port 221, and the shut-off valve fixing structure 100 is located at the maintenance port 221. The first fixing plate 130 is connected to the housing 200.
[0043] The working principle of a multi-split air conditioner outdoor unit in this embodiment is as follows:
[0044] When installing or repairing the shut-off valve, the operator loosens the bolts on the access plate 300, removes the access plate 300, then loosens the refrigerant connection nut on the shut-off valve, passes the connecting pipe connected to the indoor unit through the nut, connects it to the shut-off valve, and tightens the nut to complete the connection. After the operation is completed, the access plate is replaced and secured with screws. The shut-off valve fixing structure 100 is installed inside the housing 200, maintaining the overall aesthetics of the housing 200 and effectively preventing accidental damage to the shut-off valve during transportation. An access port 221 is provided on the housing 200; when the shut-off valve needs repair, the access plate 300 is removed to expose the access port 221, allowing for repairs.
[0045] Example 4
[0046] This embodiment is a second embodiment of a multi-split air conditioner outdoor unit. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 4 As shown, the housing 200 includes a bottom plate 210, a front panel 220, a first side panel 230, a rear panel 240, a second side panel 250, and a top cover 260. The front panel 220, the first side panel 230, the rear panel 240, and the second side panel 250 are connected sequentially. Both ends of the front panel 220, the first side panel 230, the rear panel 240, and the second side panel 250 are respectively mounted on the bottom plate 210 and the top cover 260. A first fixing plate 130 is fixedly connected to the first side panel 230, and a second fixing plate 140 is fixedly connected to the bottom plate 210. Figure 4 As shown, in this embodiment, the first side panel 230 is the right side panel, the second side panel 250 is the left side panel, and the inspection port 221 is located on the front panel 220. Figure 4 As shown, the access port 221 is located at the lower right of the front panel 220. Since the shut-off valve is generally installed on the right side of the outdoor unit of the air conditioner, adjusting the shut-off valve to the front right side does not significantly change the position of the shut-off valve. The access plate 300 is detachably connected to the front panel 220.
[0047] Because the space planning of air conditioner locations is often quite compact, the sides of the outdoor unit are often obstructed by guardrails, walls, or other structures, resulting in limited operating space and making it difficult for staff to access the shut-off valve. By opening the inspection port 221 on the front panel 220, staff can directly access the shut-off valve from the front of the outdoor unit. This not only significantly reduces the difficulty of installation and maintenance but also provides ample operating space for operators, effectively avoiding the inconvenience caused by limited space in traditional operations. This significantly improves the efficiency and safety of multi-split air conditioner shut-off valve installation and maintenance.
[0048] The inspection plate 300 is provided with knockout holes 310, such as Figure 3 As shown, the access panel 300 has a folded edge on the right side, and the knockout hole 310 is located at the folded edge on the right side of the access panel 300. By setting the knockout hole 310, the refrigerant pipe path is avoided, preventing interference with the refrigerant pipe. At the same time, when disassembling the access panel 300, it can be removed from the access panel 300 through the knockout hole 310.
[0049] like Figure 3 As shown, the inspection plate 300 adopts a double fixing method. The bottom is firmly connected to the base plate 210 by a screw, and the side is tightly fixed to the first side panel 230 by screws. This design not only enhances the stability of the overall structure, but also facilitates disassembly and maintenance in the later stage, significantly improving maintenance efficiency and achieving a perfect integration of structural design and functionality.
