[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0032] Example 1

[0033] like Figures 1-4 As shown, a special tool for disassembling the valve cover 5 of a horizontal desuperheating and pressure reducing device includes a connecting plate 1, a connecting piece 2, and a driving device 3. The connecting plate 1 is fixedly connected to the top of the desuperheating and pressure reducing device by fixing bolts. There is a space between the connecting plate 1 and the desuperheating and pressure reducing device. The connecting plate 1 has multiple through holes 12. One end of the connecting piece 2 passes through the through hole 12 and is fixedly connected to the valve cover 5 of the desuperheating and pressure reducing device. There are multiple connecting pieces 2, which are evenly distributed and connected to the top of the valve cover 5. The other end of the connecting piece 2 is higher than the upper surface of the connecting plate 1 and is locked to the connecting plate 1 by a locking piece 4. The output end of the driving device 3 is connected to the outer end face of the locking piece 4.

[0034] Specifically, one end of the connector 2 is passed through the through hole 12, and the connector 2 is fixedly connected to the valve cover 5. Then, the locking member 4 is sleeved on the top of the connector 2, and the locking member 4 is rotated, causing it to move downwards on the connector 2 until it locks the connector 2 onto the connecting plate 1. This simultaneously locks multiple connectors 2 together. Then, multiple driving devices 3 are installed on the locking member 4, and all driving devices 3 are activated simultaneously, acting on the locking member 4 to rotate downwards on the connectors 2. This causes the lower ends of the multiple connectors 2 to move the valve cover 5 upwards, removing it from the top of the de-icing and pressure-reducing device. In this embodiment, the connecting plate 1 is a 10mm thick round steel plate.

[0035] like Figures 1-4 As shown, the surface of connector 2 has external threads.

[0036] Specifically, an external thread is formed on the surface of the connector 2, forming a threaded connection between the connector 2 and the valve cover 5, the connecting plate 1, and the locking member 4, and the connector 2 moves in thread engagement with the locking member 4. When the connector 2 moves upward, it drives the valve cover 5 upward as well, moving the valve cover 5 out from the top of the de-icing and pressure-reducing device. In this embodiment, the connector 2 can be a screw or a lead screw; alternatively, the connector 2 can be other components with the same function. In this embodiment, the connector 2 uses an M20 fully threaded lead screw with L = 1000 mm.

[0037] As shown in Figures 1-4 The locking member 4 has an internal thread, and the locking member 4 is threadedly connected with the connecting member 2.

[0038] Specifically, the locking member 4 is threadedly connected with the connecting member 2, and the locking member 4 can rotate up and down along the height direction. When the connecting member 2 moves upward, the valve cover 5 is driven to move upward together, and the valve cover 5 is moved out from the top of the temperature and pressure reducing device. In this embodiment, the locking member 4 is a polygonal nut with an internal thread.

[0039] As shown in Figures 1-4 The connecting member 2 is threadedly connected to the top end of the valve cover 5.

[0040] Specifically, the connecting member 2 is threadedly connected to the top end of the valve cover 5, and the connecting member 2 and the valve cover 5 are fixedly connected together.

[0041] As shown in Figures 1-4 The driving device 3 is a driving motor, and the output end of the driving device 3 is further provided with a rotating member 31, and the rotating member 31 is fixedly connected to the output end of the driving device 3.

[0042] Specifically, the rotating member 31 is fixedly connected to the output end of the driving device 3, so that when the output end of the driving device 3 rotates, the rotating member 31 can also rotate. Then the rotating member 31 drives the locking member 4 to rotate. In this embodiment, the driving device 3 is a driving motor. Alternatively, the driving device 3 can also be other components with rotating structure.

[0043] As shown in Figures 1-4 The bottom of the rotating member 31 is provided with a connecting hole 32, one end of the connecting member 2 higher than the connecting plate 1 is inserted into the connecting hole 32, and the connecting hole 32 is adaptively connected with the outer end face of the locking member 4.

[0044] Specifically, one end of the connecting member 2 higher than the connecting plate 1 is inserted into the connecting hole 32, which facilitates the adaptive connection between the connecting hole 32 and the outer end face of the locking member 4, so that when the rotating member 31 rotates, the locking member 4 can also rotate together. Thus, the locking member 4 and the connecting member 2 form a threaded rotation. When the locking member 4 rotates to the bottom end of the connecting member 2, the connecting member 2 drives the valve cover 5 to move upward, so that the valve cover 5 is moved out from the top of the temperature and pressure reducing device. When the locking member 4 rotates to the top end of the connecting member 2, the connecting member 2 drives the valve cover 5 to move downward, so that the valve cover 5 is moved to the top of the temperature and pressure reducing device, and the valve cover 5 is completely covered on the top of the temperature and pressure reducing device.

[0045] As shown in Figures 1-4 The driving device 3 has a plurality of driving devices 3, and the plurality of driving devices 3 are respectively connected to the plurality of locking members 4.

[0046] Specifically, the plurality of driving devices 3 are evenly connected to the plurality of locking members 4, and the plurality of driving devices 3 drive the plurality of locking members 4 to rotate in the same direction or in the opposite direction synchronously, so as to move the valve cover 5 away from the top of the temperature and pressure reducing device or move the valve cover 5 to the top of the temperature and pressure reducing device. Meanwhile, the power driving is adopted, which not only ensures that the valve cover 5 is not skewed when being moved away, but also saves time and labor.

[0047] As shown in Figures 1-4 , the plurality of driving devices 3 drive the plurality of locking members 4 to rotate in the same direction or in the opposite direction synchronously.

[0048] Specifically, the plurality of driving devices 3 drive the plurality of locking members 4 to rotate in the same direction or in the opposite direction synchronously. So as to move the valve cover 5 away from the top of the temperature and pressure reducing device or move the valve cover 5 to the top of the temperature and pressure reducing device. Meanwhile, the power driving is adopted, which not only ensures that the valve cover 5 is not skewed when being moved away, but also saves time and labor.

[0049] The beneficial effects of the embodiment are: the connecting plate 1 and the valve cover 5 are connected together through the connecting member 2, the driving device 3 is started, the locking member 4 is driven by the driving device 3 to rotate downward along the height direction of the connecting member 2, so that the connecting member 2 moves upward. Meanwhile, the plurality of driving devices 3 are started, so that the plurality of connecting members 2 move upward at the same time, so that the valve cover 5 moves upward together with the plurality of connecting members 2, and the valve cover 5 is moved away from the top of the temperature and pressure reducing device. The power driving is adopted, which ensures that the valve cover 5 is not skewed when being moved away, saves time and labor.

[0050] The working process of the embodiment is: one end of the connecting member 2 is inserted through the through hole 12, and the connecting member 2 is fixedly connected with the valve cover 5, then the locking member 4 is sleeved on the top end of the connecting member 2, and the locking member 4 is rotated to move downward on the connecting member 2 until the locking member 4 locks the connecting member 2 on the connecting plate 1. Meanwhile, the plurality of connecting members 2 are locked together. Then, the plurality of driving devices 3 are installed on the locking member 4, and the plurality of driving devices 3 are started to act on the locking member 4 at the same time, so that the plurality of locking members 4 rotate toward the lower end of the connecting member 2 at the same time, so that the lower end of the plurality of connecting members 2 drives the valve cover 5 to move upward together, and the valve cover 5 is moved away from the top of the temperature and pressure reducing device. When the locking member 4 rotates toward the top end of the connecting member 2, the connecting member 2 drives the valve cover 5 to move downward, so as to move the valve cover 5 to the top of the temperature and pressure reducing device, until the valve cover 5 is completely covered on the top of the temperature and pressure reducing device.

Thus, the valve cover 5 is moved out from the top of the temperature and pressure reducing device, or the valve cover 5 is moved to the top of the temperature and pressure reducing device. At the same time, electric power is used for driving, which ensures that the valve cover 5 does not deviate when moving out, saves time and effort.
