一、进口冷水减压阀概述

进口冷水减压阀（威盾VTON），Cold water pressure reducing valve，是指用于冷水、污水、混合水等介质，将冷水流体的阀前压力减到并稳定在需要的冷水的介质流体压力值。属于直接作用式薄膜弹簧减压阀。主要由调节弹簧、膜片、活塞、阀座、阀瓣等零件组成。利用膜片直接传感下游压力驱动阀瓣，控制阀瓣开度完成减压稳压功能。
进口冷水减压阀在城市建筑、高层建筑的冷热供水系统中，可取代常规分区水管，节省设备。也可在通常的冷冷水管网中，起减压稳压作用。
本产品调压、稳压动作平稳，适用于水和非腐蚀性液体介质的管路。

Cold water pressure reducing valve (VTON) refers to a valve used for cold water, sewage, mixed water and other media to reduce and stabilize the pre valve pressure of the cold water fluid to the required fluid pressure value. Belongs to a direct acting diaphragm spring pressure reducing valve. Mainly composed of adjusting springs, diaphragms, pistons, valve seats, valve discs, and other components. Using a diaphragm to directly sense downstream pressure and drive the valve disc, controlling the valve disc opening to achieve pressure reduction and stabilization functions.

Cold water pressure reducing valves can replace conventional partition water pipes in the cold and hot water supply systems of urban and high-rise buildings, saving equipment. It can also play a role in reducing pressure and stabilizing pressure in typical cold and cold water pipe networks.

This product has stable pressure regulation and stabilization actions and is suitable for pipelines with water and non corrosive liquid media.
