Abstract

The invention provides a petroleum and petrochemical valve with a locking structure, and relates to the technical field of valves. The petroleum and petrochemical valve comprises a valve shell, a valve plate, a locking piece, a clamping piece, a locking piece slide and a locking adjusting mechanism. The beneficial technical effect is that rapid opening and closing of the valve can be realized, andopening and closing states can be automatically locked. The valve plate is slidably connected in the valve shell; the locking piece is arranged at the upper end of the valve plate; the clamping pieceis connected with the locking piece in a matched way; the clamping piece is movably connected to the locking piece slide; the locking piece slide is arranged on the locking adjusting mechanism; the locking adjusting mechanism is connected with the locking piece slide in a matched way; and the locking adjusting mechanism is arranged on the valve shell.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a petroleum and petrochemical valve with a locking structure. Background technique [0002] The patent number is CN201920377719.5 for a valve with a locking device. This utility model relates to the technical field of valves and discloses a valve with a locking device, including a valve body whose top is fixedly connected with a fixed pipe. The top of the fixed pipe is fixedly connected with a fixed nut, the top of the fixed nut is threadedly connected with a screw rod, the top of the screw rod is fixedly connected with a valve stem, and the bottom of the screw rod is fixedly connected with a fixed rod. For the valve with locking device, fixed blocks are fixed on both sides of the fixed pipe, and a compression spring is connected inside the fixed block. When the position rod is moved down, the valve stem can be rotated to control the opening and closing of the valve, the connecti...
