1、当采用0.05-0.2MPa水压时,灌溉水通过灌溉水进口(连接体圆管形凸台的中心孔)进入灌水器时,由于压力低,差动压力小于弹簧6压紧力,无法推动阀芯5,阀芯5上段51顶部的锥面51a与该连接体阶梯孔小孔段411与连接体阶梯孔中孔段412连接处的锥面41a紧配合,封住连接体与喷头部分相连接的出口,从连接体进水口进入的灌溉水只能通过阀芯5中间段的节流楔槽521节流到锥接头8和插杆9组成的滴灌芯管滴到植物根部;此时起滴灌作用。1. When the water pressure of 0.05-0.2MPa is used, when the irrigation water enters the emitter through the irrigation water inlet (the central hole of the circular tube-shaped boss of the connecting body), due to the low pressure, the differential pressure is less than the pressing force of the spring 6, and cannot Push the spool 5, and the conical surface 51a on the top of the upper section 51 of the spool 5 tightly fits with the conical surface 41a at the junction of the small hole section 411 of the connecting body stepped hole and the middle hole section 412 of the connecting body stepped hole, sealing the connecting body and the nozzle part Connected outlets, the irrigation water entering from the water inlet of the connecting body can only be throttled through the throttling wedge groove 521 in the middle section of the valve core 5 to the drip irrigation core pipe composed of the cone joint 8 and the insertion rod 9 to drip to the root of the plant; It plays the role of drip irrigation.

2、采用0.3-0.4MPa水压时,灌溉水通过灌溉水进口(连接体圆管形凸台的中心孔)进入灌水器时,由于压力高,差动压力大于弹簧6压紧力,压力灌溉水推动阀芯5向下运动,阀芯中间段52与阀芯小轴径段53之间的锥面52b封堵螺套7内孔而封堵滴灌出水流道,阀芯5上段51顶部的锥面51a离开连接体阶梯孔中孔段412连接处的锥面41a,并打开连接体与喷头部分相连接的出口,带有较大压力的灌溉水经过以下途径:连接体阶梯孔的中段412→连接体阶梯孔的小孔段411→支撑套中心孔31→扇形斜槽上的喷水口211→扇形斜弯槽21喷出,压力水持续冲击转动体2一边喷洒一边高速旋转,水射程可达3.5米,雾化程度也较好;此时起微喷灌作用。2. When the water pressure of 0.3-0.4MPa is used, when the irrigation water enters the emitter through the irrigation water inlet (the central hole of the circular tube-shaped boss of the connecting body), due to the high pressure, the differential pressure is greater than the pressing force of the spring 6, and the pressure irrigation The water pushes the spool 5 to move downward, and the taper surface 52b between the middle section 52 of the spool and the small shaft diameter section 53 of the spool blocks the inner hole of the screw sleeve 7 to block the drip irrigation flow channel.

额定工作压力(MPa):0.05-0.2(滴灌)/0.3-0.4(喷灌);Rated working pressure (MPa): 0.05-0.2 (drip irrigation)/0.3-0.4 (spray irrigation);

射程:3.5米(喷灌)流量(L/h):5(滴灌)/35(喷灌)。Range: 3.5 meters (spray irrigation) Flow rate (L/h): 5 (drip irrigation)/35 (spray irrigation).
