Three-way two-plate type harmful gas blocking and protecting integrated device

The utility model relates to the technical field of harmful gas protection, and discloses a three-way two-plate type harmful gas blocking and protecting integrated device which comprises a multi-way pipeline which is integrally machined and formed by pipes and is provided with at least one group of gas inlet end, gas outlet end and gas outlet end; the pipeline cutting-off components are arranged at the gas inlet end and the gas outlet end and electrically connected with the controller, and the controller receives a signal command of a process system and controls the pipeline cutting-off components to cut off the pipeline according to the signal command. A control signal is sent to control synchronous or independent opening or closing of the pipeline cut-off components at the gas inlet end and the gas outlet end; the device has the beneficial effects that the arranged controller can independently, synchronously or differently control each pipeline cut-off component, so that a harmful gas source is cut off quic
