A modification method of fire water monitor valve circuit to prevent the influence of induced current

Abstract

The invention discloses a method for modifying a valve line of a fire-fighting water monitor for preventing the influence of an induced current, comprising a fire-fighting water monitor, an electric valve, an electric actuator, a controller and cables, and the method for modifying a circuit for a valve of a fire-fighting water monitor for preventing the influence of an induced current It includes the following steps: Step 1: Replace the original fire water monitor valve with an electric valve; Step 2: Go deep into the site, master the electrical control system of the original fire monitor valve, and draw the circuit diagram after many times of improving the circuit diagram; Step 3: Electrically connect the electric valve to the controller through the electric actuator; step 4: perform repeated disassembly, wiring, and test, and debug the valve; step 5: debug the working state of the motor and check the working fault of the motor. The fire water monitor valve circuit modification method for preventing the influence of the induced current avoids the influence of the induced voltage on the control circuit, ensures the safety of the valve motor, and is convenient for safe production.

Description

technical field [0001] The invention relates to the related technical field of fire-fighting water monitors, in particular to a method for modifying valve circuits of fire-fighting water monitors to prevent the influence of induced currents. Background technique [0002] At present, the fire water monitor is composed of a fire monitor body and an on-site controller. It combines micro-control technology, infrared sensor detection technology, mechanical rotation control technology, and image transmission technology to automatically find the fire point, accurately locate it, and effectively and quickly extinguish the fire source. Automatic direct-current columnar or spray-spray water jets from far and near, effectively extinguishing fires while protecting personal and property safety, with on-site manual operation control and image display functions, can be forced to start to detect fire sources according to the linkage signals of other fire alarm systems, using infrared The du...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for modifying the circuit of the fire-fighting water monitor valve to prevent the influence of the induced current, so as to solve the problem that the general fire-fighting water monitor valve proposed in the above-mentioned background technology is caused by the induced voltage in the control circuit, which causes multiple valves of the fire-fighting monitor to work for a long time. The control failure can only be operated manually on site, which affects production safety. After replacing the new electric actuator, it faces the problem of how to be compatible with the control system of the fire water monitor valve
