ASCO比列调节电磁阀宜水平安装。水平安装时，阀盖宜向上。消防给水系统的减压阀阀后应有排水设施。自动喷水灭火系统的需减压时，减压阀应设置在报警阀前（沿水流方向），与单个报警阀配套设置的减压阀，可不设备用减压阀；与多个报警阀配套设置的减压阀，应设备厂用减压阀。用于热水供应工程的减压阀，应采用热水型减压阀。
采用干管干管循环方式（半循环方式）的热水供应工程，减压阀设置要求应与冷水工程相同；采用立管循环方式（全循环方式）的热水供应工程，减压阀设置应防止热水循环的破坏，各分区回水管在汇合点压力应平衡。
电动遥控阀就是水压控制的阀门，水力控制阀由一个主阀及其附设的导管﹑导阀﹑针阀﹑球阀和压力表等组成。根据使用目的﹑功能及场所的不同可演变成遥控浮球阀﹑减压阀﹑缓闭止回阀﹑流量控制阀﹑泄压阀﹑水力电动控制阀、水泵控制阀等。
SYSTEM PRESSURISATION AND DEPRESSURISATION CURVES
• WITH A SOLENOID/AIR CONTROLLED SOFT-START DEVICE
These times correspond to a supply
pressure (Pa) of 6.3 bar, a downstream
system capacity of 10 and 20litres and
a pressure of 90% Pa.
Unlike the automatic soft-start version, this version only authorises full fl ow on receiving a permanent electrical signal.
The adjustment range for the pressurisation time lies between curves (1) and (2).
Filling and venting times (in seconds):
T1 (with screw loosened by 10 turns) 9,5 15
T2 (with screw loosened by 1 turn) 44 68
