对于初次购买洒水车的朋友，对于洒水车的操作都不太了解，尤其是四位三通球阀的操作，该部件控制着洒水车的进出水操作,正确操作才能保证洒水车的正常作业。而四位三通球阀结构是很简单的，操作也不复杂，但是却很容易搞错，下面通过图文并茂的方式，来详细讲解一下！首先来看一下洒水车的四位三通球阀的整体外观：

    For the first time purchase sprinkler friend, for sprinkler operation not quite understand, especially the four three ball valve operation, the control unit with sprinkler water operation, correct operation in order to ensure the normal operation of sprinkler. While the four position three way valve structure is simple, the operation is not complex, but very easy to make a mistake, here by the illustrated way, to explain in detail! First look at the sprinkler four three ball valve 's overall appearance:

    通过以上图片可以看出，四位三通球阀的结构一眼就可以看清，但当安装到洒水车上时，通过开关不同的通道，就能实现进水和出水的操作。从图示可以看到，球阀上方有个操作杆，操作杆上有个红点，转动手柄，红点所在的方向，则该方向通道是关闭的，反之则是畅通的。在一般配置的洒水车上，右边的通道还有一个开关球阀，通过开启此开关，然后打开四位三通球阀的右侧开关，就能实现放水功能。反之，关闭四位三通球阀右侧开关，以及右侧另一个开关也关上，打开四位三通球阀另一侧开关，则能实现进水功能。

    Through the above picture can see, four position three way valve structure can see at a glance, but when mounted to the truck when the switch, through different channels, can achieve the influent and effluent of operation. Can be seen from the above, the ball valve operating rod, an operating rod has a red dot, red dot rotating handle, the direction, the direction of the channel is closed, and is in fluid. In the general configuration of the sprinkler, the right of the channel and a switch ball valve, by opening the switch, and then open the four position three way ball valve on the right side of the switch, can realize water drainage function. Conversely, off four three ball valve on the right side and the right side switch, another switch is closed, opening the four position three way ball valve side switch, can realize water function.

    洒水车上还有很多开关用的球阀，通过各种球阀的组合，还可实现泵进泵出的水泵效果，还配有消防接头，关键时刻也可用于消防灭火。小编在这建议，刚入手洒水车的朋友，购完洒水车后，一定要求洒水车厂家人员，把洒水车相关的操作方法讲解清楚。正确的操作方法事关洒水车的使用寿命，请大家一定不要小看！

    Sprinkler to still have a lot of switch valve, through a variety of ball valve combination, but also can realize the pump pump pump effect, also equipped with fire joints, critical moment can also be used for fire extinguishing. In this small series suggest, just start watering car friend, buys the sprinkler, sprinkler manufacturer personnel requirements, the sprinkler related operating method to explain clearly. The correct method of operation involves sprinkler service life, please do not look down upon!
