2. **Hollow Bulb Design**:   - The hollow bulb structure is the core of the seal, designed to compress under pressure to create a tight, watertight seal. The hollow section allows the seal to flex and adapt to the gate’s surface, accommodating any irregularities and ensuring effective sealing.   - This design is especially useful in gates that experience movement or need to adjust to varying pressure levels, as the bulb can deform as needed while maintaining the integrity of the seal.
3. **Material Composition**:   - The main body of the seal is typically made from durable elastomeric materials such as rubber or EPDM, which provide the necessary flexibility and resilience.   - The Teflon cladding is applied to the surface of the seal, providing the benefits of PTFE without compromising the flexibility and compressibility of the underlying material.
4. **Applications**:   - Teflon-cladded hollow bulb seals are ideal for use in dam gates where high durability and low maintenance are required. These seals are particularly beneficial in situations where the gates must open and close frequently, or where there is a high risk of exposure to chemicals or other corrosive elements.   - They are commonly used in spillway gates, radial gates, and other hydraulic structures where water-tight integrity is critical.
5. **Performance**:   - The combination of Teflon cladding with the hollow bulb design ensures that the seal can provide consistent, reliable sealing under various conditions. The low friction of Teflon reduces the force required to operate the gate, leading to smoother operation and less wear on mechanical components.   - The chemical resistance of Teflon ensures that the seal remains effective even in harsh environments, while its durability helps prevent degradation over time.
6. **Installation and Maintenance**:   - Proper installation is essential to ensure that the Teflon cladding does not get damaged and that the seal is correctly positioned to compress fully when the gate is closed.   - While the Teflon cladding reduces the need for frequent maintenance, regular inspections are still important to check for any signs of wear or damage. Over time, if the seal or the Teflon cladding shows signs of wear, it may need to be replaced to maintain effective sealing.
