[0037] The working principle and usage process of this utility model are as follows: When not operating the control valve 2, the protective cover 42 is securely mounted on the support plate 41 through the locking action of the locking plate 46 and the positioning box 43, providing comprehensive protection for the control valve 2 and preventing damage from external factors. When maintenance of the control valve 2 is required, the user presses the pressing plate 44 inside the positioning box 43. The pressing plate 44 drives the transmission plate 45 downwards, which in turn drives the locking plate 46 downwards, disengaging the locking plate 46 from the positioning box 43. At this time, the return spring 47 is compressed. The user can easily remove the protective cover 42 to operate the control valve 2. After operation, the user places the protective cover 42 back on the support plate 41 and releases the pressing plate 44. Under the elastic force of the return spring 47, the clamping plate 46 moves upward and re-engages with the positioning box 43, the protective cover 42 is securely installed, and continues to protect the control valve 2. The observation mirror 52 in the observation assembly 5 is set inside the observation port 51 of the protective cover 42. The user can directly observe the working status of the control valve 2 inside the protective cover 42 through the observation mirror 52 without opening the protective cover 42, which is convenient and quick.
[0038] In summary, this valve protection device, by adding functionality that facilitates the installation and disassembly of the protective cover, enables it to provide efficient protection for control valves, preventing the cumbersome, time-consuming, and labor-intensive installation and disassembly of the protective cover, and thus solving the problem of cumbersome, time-consuming, and labor-intensive installation and disassembly of the protective cover.
