Excess pressure controller capable of automatically stopping alarm function

Abstract

The invention discloses an excess pressure controller capable of automatically stopping the alarm function. The excess pressure controller capable of automatically stopping the alarm function comprises a staircase, vestibules, a signal data acquisition unit, a signal data analysis and processing control unit, a system management unit, a dual-power switch and electric switches, wherein the outer side of differential pressure measurement and control instruments are connected with a signal line, and the other end of the signal line is connected with an air valve control box. The air valve controlbox is connected with a bypass pressure release valve through a power line, a bypass pipe is fixedly installed on the outer side of the bypass pressure release valve, a pressurizing air supply channel is fixedly connected to the outer side of the bypass pressure release valve, a pressurizing air feeder is installed at the upper end of the pressurizing air supply channel, and a pressurizing air supply opening is formed in the outer side of the pressurizing air supply channel. According to the excess pressure controller capable of automatically stopping the alarm function, a SKYK excess pressure controller and an alarm device are monitored through a SKDY intelligent excess pressure monitoring host in the system management unit, the normal working state of the alarm device can be effectivelyguaranteed, and therefore automatic stopping of the alarm function can be normally completed.

Description

technical field [0001] The invention relates to the technical field of an air pressure regulating device of a positive pressure air supply system for fire fighting, in particular to a residual pressure controller with an automatic shutdown alarm function. Background technique [0002] When a fire breaks out in a high-rise building, the smoke-proof stairwell is the only vertical evacuation channel for people inside the high-rise building. For smoke-proof stairwells, fire elevator antechambers or shared antechambers that do not have natural smoke exhaust conditions, it is necessary to properly set up a mechanical pressurized air supply system to prevent the smoke from spreading to the stairwells and antechambers and ensure the smooth evacuation of people in the building. Indispensable smoke prevention measures. But area overpressure in a pressurized air system can be very dangerous. The pressure in the front room or stairwell is too high, and it is difficult or impossible to...

Problems solved by technology

[0006] The purpose of the present invention is to provide a residual pressure controller with an automatic shutdown alarm function to solve the problem that the residual pressure control devices in some current residual pressure monitoring systems proposed by the above background technology cannot effectively perform automatic monitoring during the working process. control, which will lead to the failure of its alarm function to be effectively controlled, which will lead to the problem that the use of the residual pressure control device will have a bad impact on the external
