Abstract

A medium-pressure fuel gas pipe straight-through ball valve comprises a valve body, a ball valve element and a valve rod, wherein the valve rod and the ball valve element are rotationally installed inthe valve body; the bottom of the valve rod is fixedly connected with the ball valve element; a guide block, a drive unit, a reset unit, a linkage unit and an electric control detection unit are installed on the top of the valve body; the bottom of the linkage unit is connected with the valve rod, the top of the linkage unit is in sliding connection with the guide block, and the middle of the linkage unit is in gear engaged connection with the drive unit and the reset unit; and the electric control detection unit is electrically connected with the drive unit and the guide block. The drive unit can provide opening power for the straight-through ball valve, the reset unit provides closing power for the straight-through ball valve, the straight-through ball valve is opened and closed through rotating and lifting actions of the linkage unit, the electric control detection unit is controlled by an IC flow controller, and thus remote monitoring of the straight-through ball valve is achieved.

Description

technical field [0001] The invention belongs to the technical field of gas control valves, in particular to a medium-pressure gas pipeline straight-through ball valve. Background technique [0002] In the prior art, the straight-through ball valve on the medium-pressure gas pipeline is often powered by a motor or manually, so as to realize the opening and closing control of the straight-through ball valve. Closing, although the motor or manual in the prior art can meet the opening and closing control of the ball valve, it cannot do the emergency response when a dangerous situation occurs in the gas pipeline, resulting in the slow response of the closing control of the straight-through ball valve, which is prone to danger. [0003] In addition, IC card flow controllers are currently used to control the opening and closing of the gas pipeline control valve at the user end, thereby realizing the opening and closing control of the gas pipeline. Among them, the IC card flow contr...
