Advantages of Petrogears' Patented Ceramic Float Valve (with Automatic Protection) for Oil Drilling:
1. A limit sleeve is installed below the mushroom-shaped valve core, ensuring smooth mud flow while protecting the spring from fatigue failure, thereby extending the product's service life.
2. The floating protective cylinder descends after the mud channel opens, forming a protective cavity to shield the rubber sealing ring from direct mud erosion. This design prolongs the lifespan of both the sealing ring and the tool.
3. When the rubber sealing ring is compressed to a preset level, the lower conical limiting surface of the valve seat and the upper conical surface of the mushroom-shaped valve core interlock. This mechanism prevents excessive pressure damage, enhancing the durability of the sealing ring and spring.
4. The design eliminates the long piston contact surfaces used in previous generations, improving adaptability to complex downhole mud systems and diverse operational conditions.
5. High-temperature resistance: Capable of continuous operation at 220°C.
6. Extended service life: Maintenance-free operation for over 600 hours with guaranteed effectiveness.
7. The low-pressure sealing ring (PTEE) exhibits exceptional performance, resisting all strong acids (except sodium hydroxide above 300°C), strong oxidizers, reducers, and organic solvents.
