概述

HC42T/×静音止回阀主要由阀体、阀座、导流体、阀瓣、导向套和压缩弹簧等零件组成。内部流道采用流线型，压力损失小，阀瓣行程较短，停泵能快速关闭．防止水锤水击的发生，达到静音效果。

CVKR型大口径静音止回阀采用符合水利学的轮廓设计，取得较佳的流线型水路，内部附有导流体设计能保证最小压力损失。本系列阀阀门主要用于给排水、消防、暖通、化工、电厂、冶金石化等系统，一般安装在水泵的出口处，以防倒流及水锤对泵的损害。

Overview

HC42T/X noiseless check valves are mainly composed of body, seat, diffuser, disc, guide sleeve and compression

spring etc. Featured by streamline channel, little pressure loss, short disc stroke, quick close upon stopping pump,

they function to avoid the production of water hammer and sllamming for noiseless effect.

CVKR large-caliber noiseless check valve is designed to a profile in accordance with hydraulics, provided with excellent streamline waterway, and diffuser inside to ensure minimum pressure loss.This series of valves are mainly

used in the systems of water supply and drainage, fire control, ventilation, chemicals, power plant, metallurgy and petrochemicals etc., usually mounted at pump outlet to prevent pump from damage caused by backflow and water hammer.
