产品介绍

一、进口微阻缓闭止回阀产品概述

进口微阻缓闭止回阀，Micro resistance slow closing check valve，由阀体、阀盖、阀瓣、阀轴及调节阀等组成，安装在水泵出口处用来防止介质逆流和消除破坏性水锤的止回阀，能有效地减少阀门关闭的水锤压力，可保障管网安全运行。

美国威盾VTON微阻缓闭止回阀主要用于工业、城市给排水管道和高层住宅、高级宾馆、加压输水泵的出口处。在设计上充分考虑了使用环境的要求，采用斜板式结构，达到无震动、无嘈声、运行平稳，确保宾馆、住宅环境安静，并具有节能的效果。用延缓关闭的方式使局部倒流水向系统内泄流，从而大大降低了停泵倒流的水压冲力，消除了破坏性水锤峰值的产生，截流密封采用丁腈橡胶，密封性能好、减震耐磨、使用寿命长、维修方便等特点。

Micro resistance slow closing check valve, Micro resistance slow closing check valve， A check valve composed of valve body, valve cover, valve disc, valve shaft, and regulating valve, installed at the outlet of the water pump to prevent medium backflow and eliminate destructive water hammer, can effectively reduce the water hammer pressure when the valve is closed, and ensure the safe operation of the pipeline network.

The Weidun VTON micro resistance slow closing check valve is mainly used at the outlet of industrial and urban water supply and drainage pipelines, as well as high-rise residential buildings, high-end hotels, and pressurized water pumps. The design fully considers the requirements of the usage environment and adopts a slanted plate structure to achieve no vibration, no noise, s operation, ensuring a quiet environment for hotels and residential areas, and having energy-saving effects. By delaying the shutdown, the local backflow water is released the system, greatly reducing the water pressure impulse caused by pump shutdown backflow and eliminating the generation of destructive water hammer peaks. The closure seal adopts nitrile rubber, which has good sealing performance, shock absorption and wear resistance, long service life, and convenient maintenance.
