Anti-sticking support for airless sprayer check valves
**Application Number:** 8
**Title:** Anti-Sticking Support Device for Airless Spraying Machine Check Valve
**Publication (Chinese):** CN201006510
**Inventor:** Zheng Yimei

The invention belongs to the technical field of spray equipment manufacturing, particularly relating to a utility model that provides an improved anti-sticking support device for the check valve of an airless sprayer. The device is designed to prevent adhesion between the steel ball and the valve seat caused by the sprayed medium, ensuring smooth operation and maintaining good sealing performance of the one-way valve.
The anti-sticking support device consists of a support rod, a steel ball positioned above the support rod which interacts with the check valve, and a fixing nut located below the check valve. The support rod extends through the fixing nut and is connected to a support rod seat. A knob is also attached to the support rod seat, allowing the user to rotate the knob in order to move the support rod up and down. This mechanical adjustment helps to lift the steel ball away from the valve seat, preventing it from sticking due to residue or buildup during use.
The support rod is fixedly connected to the support rod seat, and as the support rod moves, it pushes the steel ball upward, allowing it to drop back into place when released. This mechanism ensures consistent and reliable operation of the check valve, reducing maintenance and improving the overall efficiency of the airless spraying system.
By incorporating this innovative support device, the invention enhances the durability and performance of the one-way valve, making it more suitable for continuous and high-demand applications in the painting and coating industry.
