Hydraulic control valve for drip hoses

US-7455071-B2

用于稳定滴灌软管水压的液压控制阀。

专利摘要

本发明的目的是提供一种用于滴灌软管的液压控制阀,其根据水压控制水流,从而保持供给滴灌软管的水压恒定。该液压控制阀包括:软管连接器(110),其两端夹紧在分支软管(H/S)和滴灌软管(H/N)上;供水路径,具有较大直径路径(120a)和较小直径路径(120b);U形柔性杯(200);以及支撑环(300)。较大直径路径包括具有凸起(141)和凹陷(142)的阶梯座(142)。较小直径路径包括向内突出的台阶(150)。杯的一端放置为靠近向内突出的台阶,并包括凸缘(210)。支撑环(300)装配到较大直径路径中以防止杯脱出。

Original abstractThe object of this invention is to provide a hydraulic control valve for drip hoses, which controls a flow of water according to a water pressure, thus keeping a pressure of Water fed to a drip hose constant. The hydraulic control valve includes a hose connector ( 110 ) clamped at opposite ends thereof to a branch hose (H/S) and a drip hose (H/N), a water supply path having a larger-diameter path ( 120 a ) and a smaller-diameter path ( 120 b ), a U-shaped flexible cup ( 200 ), and a support ring ( 300 ). The Larger-diameter path includes a stepped seat ( 142 ) having projections ( 141 ) and depressions ( 142 ). The smaller-diameter path includes an inward projecting step ( 150 ). The cup is placed at an end thereof to be near to the inward projecting step, and includes a flange ( 210 ). The support ring ( 300 ) is fitted into the larger-diameter path to prevent a removal of the cup.
