进口膜片式水用减压阀
进口膜片式水用减压阀概述
品牌：美国欧可OKE
进口膜片式水用减压阀，Diaphragm water pressure reducing valve，也叫弹簧膜片式减压阀，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。
进口膜片式水用减压阀在城市建筑、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。也可在通常的冷热水管网中，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。

Imported diaphragm type water pressure reducing valve
Overview of imported diaphragm type water pressure reducing valve
Brand: US Ouke OKE
Diaphragm water pressure reducing valve, also known as spring diaphragm pressure reducing valve, is a direct acting diaphragm spring pressure reducing valve. Mainly composed of adjusting spring, diaphragm, piston, valve seat, valve disc and other parts. The diaphragm directly senses the downstream pressure-driven valve flap, and controls the valve opening to complete the decompression and voltage stabilization function.
The imported diaphragm type water pressure reducing valve can replace the conventional partition water pipe in the urban building and high-rise building hot and cold water supply system, saving equipment. It can also be used in the normal hot and cold water pipe network to reduce the pressure.
This product has stable voltage regulation and stable voltage regulation, and is suitable for pipelines of water and non-corrosive liquid medium.
