  • Self operated opening and closing anti blocking and unblocking spray nozzle

A device specifically designed for dredging, assisting in pile extraction, and pile insertion on offshore drilling platforms - the anti blocking and anti blocking spray valve, which is arranged on each surface of each pile shoe and forms a complete spray system inside the pile legs and pile shoes. Inject high-pressure seawater into the flushing system through a high-pressure water pump, and the seawater is sprayed out through an anti blocking and anti blocking flushing valve to achieve the purpose of dredging and eliminating pile shoe resistance;
 
Structural features:
1. The valve is equipped with a spring telescopic anti blocking mechanism to prevent the failure of the spray valve caused by the blockage of seabed mud and sand during the insertion and extraction of pile shoes;
2. The valve has a reliable unblocking function for settling mud and sand in the pipeline of the spraying system, ensuring the normal operation of the spraying system;
3. When the valve is working, it can achieve automatic spraying of multi angle and multi line jets, eliminating the adsorption and shear forces of the pile shoes;
4. The valve has a synchronous self sealing function for stopping spraying, with a short sealing time and zero blockage, which increases the safety and reliability of the spraying system;
