一、进口不锈钢水用减压阀概述

进口不锈钢水用减压阀（威盾VTON），stainless steel water water pressure reducing valve，是指阀体采用不锈钢304或者316材质，具有耐酸碱，耐腐蚀，耐生锈的功能，强度好，韧性强，能有效高精度的减压稳压的阀门。

进口不锈钢水用减压阀主要用于各种建筑给水系统、消防系统、中央空调系统、采暖系统等。它用于支管减压，可使供水压力分配更加均衡，避免部分供水超压，优化高层建筑给水分区。进口不锈钢水用减压阀可代替分区调频变速水泵，在消防给水系统上可代替分区水泵，用于家用给水系统，可保护所有的水龙头和其它水器具。

Stainless steel water pressure reducing valve (VTON) refers to a valve body made of stainless steel 304 or 316 material, which has the functions of acid and alkali resistance, corrosion resistance, rust resistance, good strength, strong toughness, and can effectively and accurately reduce pressure and stabilize pressure.

Stainless steel water pressure reducing valves are mainly used in various building water supply systems, fire protection systems, central air conditioning systems, heating systems, etc. It is used for reducing pressure in branch pipes, which can make the distribution of water supply pressure more balanced, avoid partial water supply overpressure, and optimize the water supply zoning of high-rise buildings. The imported stainless steel water pressure reducing valve can replace the partition frequency modulation variable speed water pump, and can replace the partition water pump in the fire water supply system. It is used in household water supply systems and can protect all faucets and other water appliances.

三、进口不锈钢水用减压阀工作原理

出口压力作用在隔膜底面和阀瓣底面，当它超过弹簧设定值时，压缩弹簧，使阀瓣关闭。只要下游无水流动，出口压力将基本保持在设定值（其变化量仅为入口压力变化量的8%）；当下游用水时，出口压力下降，弹簧推开隔膜，打开减压阀。水流连续流通一阵后，减压阀的开启产生自阻尼效应，使启闭动作趋于平稳。

采用直接作用隔膜式结构，内部结构非常简单，无卡阻，性能可靠，经久耐用。耐脏防水垢,不需过滤器,不需旁通管,配管极其简单,能节省大量空间和配管成本。 出口压力精密可调，在一般场合下，可以认为出口压力不受进口压力的影响（出口压力的变化量是△P1的8%）。 极佳的水力特性，压力损失小，减压比可达成10：1以上。 可满足多种减压要求，特别适用于支管减压系统。
