[0028] This application provides a low-flow-resistance intelligent pneumatic large-diameter check valve, which solves the problem that in externally installed intelligent pneumatic large-diameter check valves, the intelligent control components and pneumatic drive components are exposed to the elements, and rainwater will fall on them on rainy days, which will greatly reduce the service life of the intelligent control components and pneumatic drive components and increase their maintenance costs over time. The solution is to install a first protective cover 3 and a second protective cover 5 on the check valve body 1, which can effectively protect the pneumatic components 2 and control unit 21 on the check valve body 1, extend their service life, and reduce maintenance costs.

[0052] When it is necessary to test the pneumatic component 2 or the control unit 21, the combination of the first protective cover 3, the second protective cover 5 and the sliding cover 4 needs to be opened. First, the sliding slider 62 drives the locking block 63 to compress the spring body 61. Then, the locking block 63 and the locking groove 411 are released.
