Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation and energy storage technology, specifically a novel high-precision vacuum regulating servo butterfly valve. Background Technology

[0002] A photovoltaic inverter is a power regulation device composed of semiconductor devices, mainly used to convert DC power into AC power. It generally consists of a boost circuit and an inverter bridge circuit. The boost circuit boosts the DC voltage of the solar cells to the DC voltage required for the inverter output control, while the inverter bridge circuit converts the boosted DC voltage into an equivalent AC voltage of the commonly used frequency.

[0003] For example, the authorized announcement number "CN216112224U" describes a small-diameter vacuum regulating butterfly valve that effectively avoids the accelerated wear of the sealing ring by dust, thus greatly extending the product's service life. It is particularly suitable for vacuum regulating environments with high dust levels. The valve body adopts a variable diameter design, and the valve plate can be easily disassembled and maintained, making installation and use convenient. However, existing vacuum regulating butterfly valves use a flange structure at the lower end to connect with the pipeline. Since the butterfly valve needs to seal the internal cavity of the valve body through a horizontally rotating valve plate, but the valve plate is only connected to the valve body through a straight rotating part in the middle, the upper and lower ends of the valve plate will bear all the pipeline pressure. When the valve is suddenly closed, a water hammer effect will occur due to the pressure change. This will cause the valve plate to bear a sudden and large impact force, making it prone to deformation and bending, which seriously affects the sealing effect of the vacuum regulating butterfly valve.

[0004] The use of stepper motors as the driving device in existing technologies is mainly due to the fact that current stepper motors have a fixed step angle and cannot stop at any position. Therefore, the vacuum regulation accuracy of vacuum regulating butterfly valves is relatively low in practice. Utility Model Content

[0005] The purpose of this invention is to solve the problems of weak sealing effect and low adjustment accuracy of vacuum regulating butterfly valves, and to propose a new type of high-precision vacuum regulating servo butterfly valve.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel high-precision vacuum regulating servo butterfly valve is designed, comprising a servo butterfly valve body, a valve body, and a connecting seat. The connecting seat is fixedly installed at the lower end of the servo butterfly valve body, and the valve body is fixedly connected to the lower end of the connecting seat. The valve body has a valve plate reinforcement structure on its inner side, and the top of the servo butterfly valve body has a control button anti-accidental touch structure.

[0008] Preferably, the valve plate reinforced pressure-resistant structure includes a valve plate and a sealing cavity. The sealing cavity is fixedly opened inside the valve body. The valve plate is rotatably installed on the inner side of the sealing cavity. Multiple reinforcing ribs are fixedly installed on the outer wall of the valve plate. Pressure-resistant mesh is fixedly connected between the inner walls of the multiple reinforcing ribs. Reinforcing rings are fixedly connected to the ends of the multiple reinforcing ribs. Fitting rings are fixedly installed on the inner outer wall of the sealing cavity.

[0009] Preferably, the lower end of the servo butterfly valve body is fixedly connected to the top of the valve plate via a valve stem, and multiple mating holes are fixedly opened on the outer side of the valve body.

[0010] Preferably, the anti-accidental touch structure of the control button includes a cover plate and a locking groove. The two locking grooves are fixedly installed on both sides of the outer wall of the servo butterfly valve body. The cover plate is movably connected to the top of the servo butterfly valve body. Extension blocks are fixedly connected to both sides of the outer wall of the cover plate. Rotating shafts are rotatably connected to one side of the two extension blocks. Threaded columns are fixedly connected to the lower ends of the outer walls of the two rotating shafts. Nuts are threadedly connected to the lower ends of the two threaded columns.

[0011] Preferably, the tops of the two nuts are movably connected to the lower part of the locking groove, and the two threaded posts are movably connected to the inner side of the locking groove.

[0012] Preferably, a control button is fixedly installed at the top of the servo butterfly valve body, and the lower end of the control button is electrically connected to the servo butterfly valve body.

[0013] This utility model proposes a novel high-precision vacuum regulating servo butterfly valve, which has the following advantages: the inner diameter of the sealing cavity can match the diameter of the valve plate, thereby achieving the valve sealing effect; the reinforcing ribs are supported by three high-strength carbon steel supports, and the three reinforcing ribs are overlapped and welded to the side wall of the valve plate; the pressure-resistant mesh is a mesh woven from stainless steel wire and welded to multiple reinforcing ribs. In this way, the reinforcing ribs and the pressure-resistant mesh can form a good reinforcement for the valve plate as a whole; the reinforcing ring is used to fix the overall shape of the valve plate so that it is not easily deformed; by using multiple methods to reinforce the valve plate with high pressure, the sealing effect of the novel high-precision vacuum regulating servo butterfly valve is improved.

[0014] By employing a servo motor, which differs from a stepper motor (which has a fixed step angle and cannot stop at any position), the servo motor can stop at any position and achieve high-precision control of vacuum regulation. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] Example 1:

[0024] Please see Figure 1-6 In this embodiment, a novel high-precision vacuum regulating servo butterfly valve includes a servo butterfly valve body 1, a valve body 2, and a connecting seat 3. A valve stem is rotatably mounted inside the connecting seat 3. When the servo butterfly valve body 1 is connected to a power source, it can drive the lower valve stem to rotate and control the valve plate 51, thereby achieving the sealing of the valve plate 51 inside the valve body 2. The connecting seat 3 is fixedly installed at the lower end of the servo butterfly valve body 1. The servo butterfly valve body 1 is a publicly disclosed prior art, composed of a drive board, servo motor, button switch, display screen, connector, cooling fan, and other structures. The servo motor can achieve stop and lock at any position and has stepless adjustment capability. The lower end of the connecting seat 3 is fixedly connected to the valve body 2. The valve body 2 can be installed by docking with pipes through docking holes 4 on both sides. The inner side of the valve body 2 is provided with a valve plate reinforcement and pressure resistance structure 5. The top of the servo butterfly valve body 1 is provided with a control button anti-accidental touch structure 7.

[0025] By employing a servo motor, which differs from a stepper motor (which has a fixed step angle and cannot stop at any position), the servo motor can stop at any position and achieve high-precision control of vacuum regulation.

[0026] The valve plate reinforced pressure-resistant structure 5 includes a valve plate 51 and a sealing cavity 56. The sealing cavity 56 is fixedly located inside the valve body 2. The inner diameter of the sealing cavity 56 matches the diameter of the valve plate 51, thereby achieving the valve sealing effect. The valve plate 51 is rotatably mounted on the inner side of the sealing cavity 56. Multiple reinforcing ribs 52 are fixedly mounted on the outer wall of the valve plate 51. Each reinforcing rib 52 has three high-strength carbon steel supports. The three reinforcing ribs 52 are overlapped and welded to the side wall of the valve plate 51. Pressure-resistant mesh 53 is fixedly connected between the inner walls of the multiple reinforcing ribs 52. The pressure-resistant mesh 53 is woven from stainless steel wire. The mesh is welded to multiple reinforcing ribs 52. In this way, the reinforcing ribs 52, together with the pressure-resistant mesh 53, can form a good reinforcement for the valve plate 51. The ends of the multiple reinforcing ribs 52 are fixedly connected to reinforcing rings 54. The reinforcing rings 54 are made of stainless steel rings that surround the outer wall of the valve plate 51. The reinforcing rings 54 are used to fix the overall shape of the valve plate 51 so that it is not easily deformed. The inner outer wall of the sealing cavity 56 is fixedly installed with a fitting ring 55. The fitting ring 55 is made of rubber material. In this way, the fitting ring 55 will fit tightly between the outer wall of the valve plate 51 and the sealing cavity 56. The elasticity of the rubber material can reduce leakage.

[0027] The inner diameter of the sealing cavity 56 matches the diameter of the valve plate 51, thus achieving the valve sealing effect. The reinforcing rib 52 is supported by three high-strength carbon steel supports, which are welded to the side wall of the valve plate 51. The pressure-resistant mesh 53 is a mesh woven from stainless steel wire and welded to multiple reinforcing ribs 52. In this way, the reinforcing ribs 52 and the pressure-resistant mesh 53 can effectively reinforce the valve plate 51. The reinforcing ring 54 is used to fix the overall shape of the valve plate 51 so that it is not easily deformed. By using multiple methods to reinforce the valve plate with high pressure, the sealing effect of the new high-precision vacuum regulating servo butterfly valve is improved.

[0028] The lower end of the servo butterfly valve body 1 is fixedly connected to the top of the valve plate 51 via the valve stem, and multiple mating holes 4 are fixedly opened on the outer side of the valve body 2.

[0029] The control button anti-accidental touch structure 7 includes a cover plate 71 and locking grooves 75. Two locking grooves 75 are fixedly installed on both sides of the outer wall of the servo butterfly valve body 1. The cover plate 71 is movably connected to the top of the servo butterfly valve body 1. The cover plate 71 is made of a stainless steel metal shell with the same size and specifications as the top of the servo butterfly valve body 1. Extension blocks 72 are fixedly connected to both sides of the outer wall of the cover plate 71. The two extension blocks 72 are welded to both sides of the cover plate 71. A rotating shaft 73 is rotatably connected to one side of each extension block 72. The rotating shaft 73 can control the threaded post 74 to rotate along the end of the extension block 72. Threaded posts 74 are fixedly connected to the lower end of the outer wall of the two rotating shafts 73. The lower ends of the two threaded posts 74 are threaded... The cover plate 71 is connected with nuts 76. When fixing the cover plate 71, the cover plate 71 is placed above the servo butterfly valve body 1. The cover plate 71 can protect the inner control button 6 from being accidentally touched. In this way, the threaded posts 74 on both sides rotate along the rotating shaft 73 to reach a vertical state. The vertical threaded posts 74 can be inserted into the locking grooves 75 on both sides. Then, the threaded posts 74 can be fixed by rotating the nuts 76. The cover plate 71 cannot be removed from the servo butterfly valve body 1. On the contrary, the cover plate 71 can be lifted by removing the nuts 76 and the threaded posts 74 to operate the control button. The tops of the two nuts 76 are movably connected to the bottom of the locking groove 75, and the two threaded posts 74 are movably connected to the inside of the locking groove 75.

[0030] Working principle:

[0031] The new high-precision vacuum regulating servo butterfly valve is equipped with an independently operating electronic control system. It adopts low-pressure control, which enables the device to operate in low-pressure environments, improving safety and efficiency. It also uses a servo motor driven by a driver to achieve stepless adjustment of the valve body and has the ability to stop at any position. By using a servo motor, unlike a stepper motor, the servo motor can achieve stopping at any position and complete high-precision control of vacuum regulation.

[0032] The connecting seat 3 has a valve stem that rotates inside. When the servo butterfly valve body 1 is connected to the power supply, it can drive the valve stem below to rotate and control the valve plate 51, thereby achieving the sealing of the valve body 2 by the valve plate 51. The connecting seat 3 is fixedly installed at the lower end of the servo butterfly valve body 1. The servo butterfly valve body 1 is a publicly available technology and is composed of a drive board, servo motor, push button switch, display screen, connector, cooling fan and other structures. The servo motor can achieve stop and lock at any position and has stepless adjustment capability.

[0033] The valve plate reinforcement structure of the new high-precision vacuum regulating servo butterfly valve:

[0034] The inner diameter of the sealing cavity 56 matches the diameter of the valve plate 51, thus achieving the valve sealing effect. The reinforcing rib 52 is supported by three high-strength carbon steel supports. The three reinforcing ribs 52 are overlapped and welded to the side wall of the valve plate 51. The pressure-resistant mesh 53 is a mesh woven from stainless steel wire and welded to multiple reinforcing ribs 52. In this way, the reinforcing ribs 52 and the pressure-resistant mesh 53 can form a good reinforcement for the overall valve plate 51. The reinforcing ring 54 is used to fix the overall shape of the valve plate 51 so that it is not easily deformed. The inner and outer walls of the sealing cavity 56 are fixedly installed with a fitting ring 55. The fitting ring 55 is made of rubber material. In this way, the fitting ring 55 will be tightly fitted between the outer wall of the valve plate 51 and the sealing cavity 56.

[0035] The new high-precision vacuum regulating servo butterfly valve has an anti-accidental touch function:

[0036] When fixing the cover plate 71, the cover plate 71 is placed above the servo butterfly valve body 1. The cover plate 71 can protect the inner control button 6 from being accidentally touched. In this way, the threaded posts 74 on both sides rotate along the rotating shaft 73 to reach a vertical state. The vertical threaded posts 74 can be inserted into the locking grooves 75 on both sides. Then, the threaded posts 74 can be fixed by rotating the nut 76. The cover plate 71 cannot be removed from the servo butterfly valve body 1. On the contrary, the cover plate 71 can be lifted by removing the nut 76 and the threaded posts 74 to operate the control button. This avoids the control button being exposed when not in use.

[0037] Example 2:

[0038] Please see Figure 1-6 In this embodiment, a novel high-precision vacuum regulating servo butterfly valve also includes a control button 6 fixedly installed on the top of the servo butterfly valve body 1. The lower end of the control button 6 is electrically connected to the servo butterfly valve body 1. The control button 6 is a prior art technology that can open / close the power supply of the electric valve. The button switch includes: rocker switch, push button switch, and membrane switch.

[0039] Working principle:

[0040] Control button 6, through circuitry, in conjunction with a control drive board, servo motor, display screen, connectors, cooling fan, and other components, can achieve stop locking of the valve at any position and has stepless adjustment capability.
