Electrically-controlled Check Valve for pipelines

The invention discloses an electrically-controlled check valve for pipelines, comprising a body, wherein, a valve body is arranged at the lower end of the body, a supporting column is fixed at the 5 lower end of the valve body on both sides, and a supporting base is clamped at the lower end of the supporting column, a filter screen structure is in threaded connection on one side in the valve body, and filter screens are arranged at the upper and lower ends of the filter screen structure, clips are fixed at one end of the filter screen structure on both sides, and a handle is in movable connection with the clips, an activated carbon screen is clamped on the side in the valve body away from the 10 filter screen structure. The invention has the following beneficial effects: The body is easily supported by the supporting column and supporting base in an adjustable way, so that the body and the pipeline are connected much more stably, the filter screen structure can realizing filtering for the pipeline to prevent large particle impurities included from entering the valve body and causing clogging of the valve body, the activated carbon screen can effectively absorb oil and prevent the 15 inside of the valve body from being damaged by oil corrosion.
