Abstract
The utility model discloses a novel unfurled type double-gate-segment gate valve which mainly solves the problem that an existing gate valve is large in abrasion on a sealing face in a valve body in opening and closing processes, and therefore airtightness of a mechanism is influenced. The novel unfurled type double-gate-segment gate valve is characterized in that a main gate segment is connected with a valve rod, a V-type sliding groove is formed in the main gate segment, a triangular protruding block matched with the sliding groove is arranged on an auxiliary gate segment, a stop block is arranged on the V-type sliding groove, the stop block is provided with a first position and a second position, the first position is contacted with the top end of the triangular protruding block, the second position is separated from the top end of the triangular protruding block, a first placing groove is formed in the main gate segment, a second placing groove is formed in the auxiliary gate segment, the first placing groove and the second placing groove can be jointed together to form a placing cavity, a placing control piece is arranged in the placing cavity, and the placing control piece is hinged to the first placing groove and the second placing groove. According to the novel unfurled type double-gate-segment gate valve, extrusion of the gate segments on the sealing face in the initial stage of opening of the valve and the later stage of closing of the valve is reduced, on the premise that the airtightness of the mechanism is ensured, abrasion on the sealing face is reduced, and the airtightness of the mechanism is improved.
