After the spray system is turned off, the nozzle continues to drip, which is a very common phenomenon. In some industries (such as spray cleaning, spray cooling, etc.), the nozzle drip has almost no effect on the spray system, so we do not Leave it alone. But in some specific fields (such as product precision spraying, chemical spraying, quantitative spraying, etc.), dripping from the nozzle will have a huge impact on the spray system. For this reason, we have designed two anti-drip solutions for your choice.

The first solution is to install a pressure spring inside the nozzle, and install a sealing ball at the other end of the spring. When the pressure in the pipeline is less than the spring pressure, when the spring is against the sealing ball, the nozzle is closed. It will drip from the nozzle. When the pipeline pressure is greater than the spring pressure, the sealing ball is pushed open, the nozzle channel opens immediately, and the nozzle starts to spray. The advantages of this solution are low cost, high flexibility, and good anti-drip effect. The disadvantage is that it is only suitable for occasions with a large pressure range.

Because the first solution requires higher system pressure, we designed another solution to prevent dripping. This solution uses solenoid valves or pneumatic valve devices to quickly close the pipeline when the controller issues a command to make the pipeline pressure It is lost from the water pump, and the nozzle is in a state of internal and external pressure balance instantly, which prevents excess liquid from dripping at the nozzle. This solution has a wide range of uses. It can be modified in the original spray system, or you can order ours Pneumatic or electromagnetic nozzle, the nozzle is integrated with the valve.
