The utility model discloses a
gate valve opening and closing tool which comprises a T-shaped body. The bottom of the T-shaped body is connected with a clamping piece through a
ratchet. During operation, for a buried pipeline, firstly, one end of the transverse rod of the T-shaped main body is inserted into an opening hole of an inspection well cover, the far end of the vertical rod is held by a hand, the inspection well cover can be opened according to the lever principle, then a tool is turned, the clamping piece is inserted into a hand wheel of a
gate valve, the transverse rod serves as a
handle at the moment, and the hand wheel of the
gate valve can be easily rotated due to the fact that the transverse rod has enough length and is combined with a
ratchet wheel. Corresponding to an elevated pipeline, an operator stands on the ground, lifts the tool to enable the clamping piece to be inserted into the gate valve hand wheel, and then rotates the T-shaped main body, so that the gate valve can be opened. Due to the
ratchet wheel, the two hands do not need to be exchanged, and the tool cannot fall off. And the safety is high. Due to the fact that the vertical rod of the T-shaped body is long, even if the valve element of the gate valve pops up under the pressure of a pipeline, the operator has enough time to avoid the valve element.
