1. Structural Features and Benefits
The pressure balanced plug valve offers a range of structural features and benefits that make it an exceptional choice for fluid control applications. Let's explore some key features and their corresponding benefits:
- Rational Design and Reliable Sealing: The pressure balanced plug valve not only boasts an appealing exterior but also features a rational structure and dependable sealing mechanism. Its pressure balancing design facilitates smooth valve operations while enhancing sealing efficacy.
- Oil Groove Lubrication Design: Introducing oil grooves between the valve body and sealing surface enables the injection of sealing grease into the valve seat through a designated oil nozzle. This augmentation further bolsters sealing performance, ensuring sustained stable valve operation.
- Flexible Configuration: Tailoring component materials and flange dimensions to actual operating conditions or user preferences allows for flexible configuration, meeting a spectrum of engineering requirements. This enhances product adaptability and versatility.
2. Distinctive Advantages of Pressure Balanced Plug Valve
The pressure balanced plug valve stands out due to its distinctive advantages, making it a preferred choice in fluid control applications. Let's explore the unique benefits that set the pressure balanced plug valve apart:
A. Inverted Installation with Pressure Balancing Structure: Employing an inverted installation method with an upper check valve, the valve capitalizes on the differential cross-sectional area of the plug. During valve closure, high-pressure sealing oil prompts upward lifting force on the plug, significantly enhancing sealing effectiveness.
B. Torque Reduction and Seal Preservation: Upon valve opening, the high-pressure sealing oil in the upper chamber exerts downward pressure on the plug, creating a minute gap between the plug and valve body sealing surface. This minimizes rotational torque requirements and safeguards sealing components, thereby prolonging their service life.
C. Adaptation to High-Temperature Environments: In high-temperature conditions, the plug's thermal expansion is accommodated through vertical movement, preventing sealing component jamming and ensuring uninterrupted valve operation.
