Abstract

The invention provides a quick switching device for a valve, which comprises a multi-turn electric device, a cycloidal pin wheel speed reducer, an electromagnetic clutch, a ball screw assembly, a hollow push rod rack, a gear, a spring seat and a combined spring, wherein the hollow push rod rack is provided with a limit device in a matching way; the electromagnetic clutch, the ball screw assembly,the hollow push rod rack, the limit device and the gear are arranged in a gearbox body in a sealing way; the upper connector end of the gearbox body is fixedly connected with the cycloidal pin wheel speed reducer; a connecting hole is formed on the gearbox body; the spring seat and the combined spring are arranged in a spring drum; the spring drum is fixedly connected with the lower connector endof the gearbox body; the centers of the two connector ends of the gearbox body are on the same line; and the symmetrical center of the connecting hole on the gearbox body and the center of the gear are on the same line. The quick switching device avoids the damage and oil leakage of pressure pipe fittings, reduces the investment and maintenance cost and is more reliable and safer to use.

Description

technical field [0001] The invention relates to a valve quick switching device, in particular to a device for gas pipelines in the metallurgical industry, which drives a partial rotation of a valve to realize quick opening or closing. Background technique [0002] At present, the bypass pipeline of the blast furnace gas residual pressure turbine power generation device is equipped with a hydraulic quick-opening butterfly valve. The gas flows through the bypass pipe to ensure the safe operation of the gas system. Since bypass quick-opening butterfly valves are mostly driven by hydraulic servo cylinders, it is easy to cause vibration damage to hydraulic pipelines and joints, damage to hydraulic components, and oil leakage accidents in the hydraulic system during use. Contents of the invention [0003] The purpose of the present invention is to provide a valve quick switching device, which overcomes the shortcomings of the traditional valve hydraulic drive device servo cylin...
