ASCO比列調(diào)節(jié)電磁閥宜水平安裝。水平安裝時(shí)，閥蓋宜向上。消防給水系統(tǒng)的減壓閥閥后應(yīng)有排水設(shè)施。自動(dòng)噴水滅火系統(tǒng)的需減壓時(shí)，減壓閥應(yīng)設(shè)置在報(bào)警閥前（沿水流方向），與單個(gè)報(bào)警閥配套設(shè)置的減壓閥，可不設(shè)備用減壓閥；與多個(gè)報(bào)警閥配套設(shè)置的減壓閥，應(yīng)設(shè)備廠用減壓閥。用于熱水供應(yīng)工程的減壓閥，應(yīng)采用熱水型減壓閥。
采用干管干管循環(huán)方式（半循環(huán)方式）的熱水供應(yīng)工程，減壓閥設(shè)置要求應(yīng)與冷水工程相同；采用立管循環(huán)方式（全循環(huán)方式）的熱水供應(yīng)工程，減壓閥設(shè)置應(yīng)防止熱水循環(huán)的破壞，各分區(qū)回水管在匯合點(diǎn)壓力應(yīng)平衡。
電動(dòng)遙控閥就是水壓控制的閥門，水力控制閥由一個(gè)主閥及其附設(shè)的導(dǎo)管﹑導(dǎo)閥﹑針閥﹑球閥和壓力表等組成。根據(jù)使用目的﹑功能及場所的不同可演變成遙控浮球閥﹑減壓閥﹑緩閉止回閥﹑流量控制閥﹑泄壓閥﹑水力電動(dòng)控制閥、水泵控制閥等。
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
