進口冷水減壓閥
一、進口冷水減壓閥
品牌：美國歐可OKE
進口冷水減壓閥，Cold water pressure reducing valve，是指用于冷水、污水、混合水等介質，將冷水流體的閥前壓力減到并穩定在需要的冷水的介質流體壓力值。屬于直接作用式薄膜彈簧減壓閥。主要由調節彈簧、膜片、活塞、閥座、閥瓣等零件組成。利用膜片直接傳感下游壓力驅動閥瓣，控制閥瓣開度完成減壓穩壓功能。
進口冷水減壓閥在城市建筑、高層建筑的冷熱供水系統中，可取代常規分區水管，節省設備。也可在通常的冷冷水管網中，起減壓穩壓作用。
本產品調壓、穩壓動作平穩，適用于水和非腐蝕性液體介質的管路。

Imported cold water pressure reducing valve
First, the imported cold water pressure reducing valve
Brand: US Ouke OKE
Cold water pressure reducing valve refers to the medium fluid pressure value used for cold water, sewage, mixed water and other medium to reduce the pre-valve pressure of the cold water fluid and stabilize it in the required cold water. It is a direct acting membrane 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 cold 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 cold and cold water 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.
