減壓穩壓型室內消火栓產品符合 GB3445-2018( 室內消火栓）規定的全部性能要求，保持了普通室內消火栓的外貌和外形尺寸標準的接口形式，以及傳統的安裝、操作方式，在此基礎上增加了自動減壓穩壓功能，不論進口壓力高低不同，管網內壓力產生波動和變化，其出口壓力均可減壓穩壓在理想的使用壓力值上，因而在工程設計中無需進行計算，安裝時利于調試。

Indoor fire hydrant decompression regulator products meet the requirements of GB3445-2018 (indoor fire hydrant) all performance requirements, maintain the appearance and shape dimension of common indoor fire hydrant interface form of standards, as well as the traditional way of installation, operation, on the basis of this increase the function of automatic decompression regulator, regardless of high and low different inlet pressure, the pressure in the pipe network to fluctuate and change, the outlet pressure can be reduced pressure regulator on the use of the ideal pressure value, and need for calculation in the engineering design, installation debugging.
