The residual pressure monitoring system manufacturers tell you what is the residual pressure controller

The residual pressure controller is an electrical control unit and the central nerve of the entire residual pressure monitoring system . The residual pressure controller plays an important role in the residual pressure control of the entire positive pressure air supply system, and is an indispensable and important part of the residual pressure monitoring system . The residual pressure controller is mainly used to receive the residual pressure detector signal, and to control the bypass valve (electric multi-page split regulating valve) to open and close by controlling the electric pressure relief actuator . It has an information upload function, which can upload the overpressure pressurization signal of the residual pressure detector and the opening and closing signal of the bypass valve to the residual pressure monitor (host) , and can be remotely controlled by the host installed in the fire control room.

The residual pressure controller is mainly divided into two types according to the installation environment and shape:

One is the control box, also known as the air valve control box, the size is 300*400*250 (mm). The appearance is similar to the distribution box, and it can be equipped with 24V or 220V control power according to the type of electric actuator. Independent installation, you can choose indoor/outdoor box according to indoor/outdoor environment. Its advantages are flexible installation, no space restrictions, and easy maintenance; its disadvantages are also obvious, heavy and inconvenient for transportation, and relatively complicated installation.

One is the control module. As the new residual pressure control unit, it is mounted on a guide rail with a size of 130*95*58 (mm) and is installed in the distribution box of the pressurized fan. Its advantage is that it is easy to transport, more convenient to install, save space, more functional than the control box, compatible with 24V and 22V electric actuators.

Shenzhen Lingxiang Equipment Co., Ltd. developed the evacuation channel residual pressure monitoring system strictly based on the national standards GB50016-2014 "Code for Fire Protection Design of Buildings" and GB51251-2017 "Technical Standards for Building Smoke Control and Exhaust Systems", and GB16806-2006 "Fire Control Linkage Control System" . At present, the application areas of Lingxiang's residual pressure monitoring system have covered airports, hotels, hospitals, real estate and other industries, and maintain in-depth cooperation with major real estate developers.
