概述

HC42T/×止回閥主要由閥體、閥座、導(dǎo)流體、閥瓣、導(dǎo)向套和壓縮彈簧等零件組成。內(nèi)部流道采用流線型，壓力損失小，閥瓣行程較短，停泵能快速關(guān)閉．防止水錘水擊的發(fā)生，達(dá)到效果。

CVKR型大口徑止回閥采用符合水利學(xué)的輪廓設(shè)計，取得較佳的流線型水路，內(nèi)部附有導(dǎo)流體設(shè)計能保證最小壓力損失。本系列閥閥門主要用于給排水、消防、暖通、化工、電廠、冶金石化等系統(tǒng)，一般安裝在水泵的出口處，以防倒流及水錘對泵的損害。

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.
