The protective component 2 includes a protective bottom frame 202, and clamping mounting rings 201 are provided on both sides of the protective bottom frame 202. The clamping mounting rings 201 are installed on the outside of the electric butterfly valve body 1. One side of the protective bottom frame 202 is hinged to the protective top frame 204 through a connecting hinge 203. A closing block 206 is provided on the other side of the protective bottom frame 202 and the protective top frame 204. A closing bolt 207 is threaded inside the closing block 206. A rubber sealing plate 205 is fixedly connected to one side of the closing surface of the protective top frame 204.

[0020] In this embodiment, as Figure 3 and Figure 4As shown, the protective component 2 also includes a fitting groove 208, which opens and closes inside the clamping mounting ring 201. The fitting groove 208 is adapted to the rubber sealing plate 205. The fitting groove 208 is designed to fit tightly with the rubber sealing plate 205. When the protective top frame 204 and the protective bottom frame 202 are closed, the rubber sealing plate 205 will be embedded in the fitting groove 208, effectively preventing external dust, moisture and other impurities from entering the interior of the electric butterfly valve body 1. The clamping mounting ring 201 is used to fix and support the protective component 2.

[0021] In this embodiment, as Figure 2 , Figure 3 and Figure 5 As shown, the cleaning component 3 includes an exhaust frame 301, which is fixedly connected to the inside of the protective top frame 204. The cleaning component 3 also includes an exhaust duct 303, which is fixedly connected to the top of the exhaust frame 301. A drop pipe 304 is fixedly connected to the side surface of the exhaust duct 303. An exhaust fan 305 is installed inside the exhaust duct 303, and a filter screen is installed inside the exhaust duct 303, located near the exhaust fan 305 at the connection port of the drop pipe 304. The protective bottom frame 202... The protective component 2 is equipped with a side-opening air inlet for gas entry, and a dust filter is installed inside the air inlet (to prevent external gas impurities from entering the interior of the protective component 2). When the protective component 2 is closed, the cleaning component 3 is activated, drawing air from the interior of the protective component 2 through the exhaust pipe 303, while simultaneously filtering impurities from the internal gas through the filter. When the exhaust fan 305 is not working, the filter can also prevent external gas impurities from entering the interior of the protective component 2 through the exhaust pipe 303. The operation of the exhaust fan 305 accelerates the internal gas flow and improves the heat dissipation effect.

Then, the protective top frame 204 is hinged to the protective bottom frame 202 using the connecting hinge 203. In this way, the electric butterfly valve body 1 inside can be protected after the two frames are closed. The design of the rubber sealing plate 205 and the fitting groove 208 makes the two frames more airtight after they are closed. Moreover, with this structure, the electric butterfly valve body 1 inside can be manually operated or inspected simply by flipping open the protective top frame 204. Then, by installing the cleaning component 3, the valve body can be cleaned by... The air frame 301 is installed inside the protective top frame 204, and the other end of the exhaust duct 303 is equipped with an exhaust fan 305. When it is turned on, it can draw the internal air out of the exhaust duct 303 and remove impurities in the internal air. After the exhaust fan 305 stops, the impurities will enter the falling duct 304 under their own gravity and be collected in the storage box 11. The impurities inside the storage box 11 can be cleaned periodically by disassembling the storage chamber 10. When the exhaust fan 305 is turned on, it can also accelerate the air flow inside the protective component 2, thereby improving the heat dissipation efficiency of the electric butterfly valve body 1.
