■Structure and purpose
This factory production GFDHH 44 H/ 47 X micro resistance slow close check valve is mainly used for industrial, urban water supply and drainage and pipeline high-rise residential, senior hotel, pressurized water pump outlet. On the design fully consider the requirements of the use of the environment, using inclined plate structure, no vibration, no noise, smooth operation, ensure that the hotel quiet, residential environment, and has the effect of the link chain. Slow closing of way that local back in discharge water to the system, thus greatly reduces the stopped flow back water pump pressure impulse and eliminates the destructive water hammer peak, intercepting seal USES NBR, sealed performance is good, shock absorption, abrasion resistance, long service life, convenient maintenance, etc.
GFDHH 44 H / 47 X butterfly check valve buffer is mainly used in industrial water supply and drainage, sewage treatment plant of the water pump outlet, prevent the network medium counter-current, automatic eliminate the destructive water hammer, so as to ensure the pump and pipeline from being damaged. This valve is mainly composed of body, disc, buffering device and trace of regulating valve. The product has the advantages of novel structure, small volume, small fluid resistance, smooth operation, reliable sealing, scouring resistance, wear resistance, buffering performance is good wait for a characteristic, is the best product for industrial water and urban sewage.
