给水栓是半固定式喷灌工程和低压管道输水灌溉工程地埋管网与地面灌溉设施连接的关键部件 ,常由上下阀体两部分组成 ,下阀体常年固定在出地三通管上 ,上阀体只能与一种管径连接 ,功能比较单一、价格也比较高 ,尤其下阀体易遭人为破坏 ,不便管理。针对上述问题 ,我们对给水栓装 Water supply is a semi-fixed sprinkler irrigation projects and low-pressure pipe water irrigation works buried pipe network and ground irrigation facilities connected to the key components, often by the upper and lower valve body composed of two parts, the valve body perennial fixed on the tee, On the valve body can only be connected with a diameter, the function is relatively simple, the price is relatively high, especially the lower body is vulnerable to man-made damage, inconvenient management. In response to the above problems, we tapped the water
