The utility model relates to a pressure reducing dripping type water pipe, which comprises a pipe body, a pressure reducing part and a water seepage structure.The pipe body encloses the water channel.The first side part of the pressure reducing part is connected with the pipe body.Seepage structure includes pressure reducing channel, inlet channel and outlet channel.The pressure reducing flow passage is arranged in the pressure reducing part and comprises a first winding section, a second winding section and a straight section, and the second winding section is connected between the first winding section and the straight section.The water inlet is arranged at the pressure reducing part and extends through the first side of the pressure reducing part to the pipe body and is connected between the water channel and the first winding section.The outlet channel is arranged at the pressure reducing part, communicated with the straight section, and penetrates the second side of the pressure reducing part.Thus, water enters the decompression channel from the water channel through the inlet channel and reduces the speed through the first and second winding sections, so as to slowly drip into the soil from the outlet channel at a lower water pressure and flow rate, thereby prolonging the irrigation time.一種減壓滴滲式水管，包括管體、減壓部及滲水結構。管體圍構水道。減壓部的第一側部與管體相接。滲水結構包含減壓流道、入水道及出水道。減壓流道設於減壓部且包含第一蜿蜒段、第二蜿蜒段及直線段，第二蜿蜒段連通於第一蜿蜒段與直線段之間。入水道設於減壓部且延伸穿過減壓部的第一側部至管體而連通於水道與第一蜿蜒段之間。出水道設於減壓部，與直線段相通，並且貫穿減壓部的第二側部。藉此，水從水道經由入水道進入減壓流道並藉由第一、第二蜿蜒段減壓降速，從而以較低的水壓和流速自出水道向外緩慢地滴滲至土壤中，藉以延長灌溉時間。
