Ball valve fatigue detection equipment

Abstract

The utility model relates to the technical field of ball valves, and discloses a ball valve fatigue detection device, which comprises a supporting mechanism and a ball valve main body, the supporting mechanism comprises two opposite vertical frames, the upper top ends of the two vertical frames are fixedly connected with a top plate, and a driving mechanism is arranged to drive a limiting mechanism to work. The two limiting plates synchronously draw close to the direction of the ball valve body with the help of a first threaded lead screw, at the moment, a sealing air pipe is connected with an air inlet pipe on the outer wall of the ball valve body, and then starting or closing of the ball valve body is achieved with the help of a downward moving mechanism; due to the fact that the two sets of sealing air pipes and the two sets of air guide pipes are arranged, starting and closing of the ball valve body need to be controlled all the time in the detection process, and detection of the ball valve body can be rapidly achieved through cooperative work of the driving mechanism, the downward moving mechanism and the limiting mechanism.
