Chinese Pneumatic Knife Gate Valve (Model: PZ673PU) for Sewage and Sand Treatment - Polyurethane Material, Wear-resistant and Zero-leakage Valve
1. Basic Parameters and Core Configurations
Model Specification: Standard model PZ673PU, adopts pneumatic drive method, compatible with common pipe diameters in industrial pipelines (can be customized according to requirements), meeting the control requirements for transporting harsh media such as sewage and sediment.
Material Characteristics: The key sealing components of the valve body are made of high-quality polyurethane material, which has excellent wear resistance and elasticity, effectively resisting the erosion and abrasion caused by sediment particles, and achieving a tight seal; The valve plate and flow channel are designed to be compatible with high-impurity media, reducing the risk of blockage and extending the service life of the valve.
Structural Design: Adopting the classic structure of a knife gate valve (plug valve), the valve plate moves vertically to achieve control of opening and closing, with a smooth flow channel without obstructions, low resistance in medium flow, and particularly suitable for sewage transportation systems containing a large amount of sediment and suspended matter.
2. Core Advantages and Performance Highlights
Durable and Resistant to Damage: The high wear resistance of polyurethane material is optimized for scenarios of solid particle erosion and grinding in sewage and sediment. Compared to ordinary rubber or metal sealing components, the service life is increased by 3-5 times, reducing the frequency of replacement costs.
Zero Leakage Sealing: The valve plate is closely attached to the sealing surface, and the elastic compensation ability of polyurethane can counteract minor wear or installation deviations, ensuring no medium leakage during the opening and closing process, avoiding environmental pollution and medium waste, and meeting industrial environmental protection and safety standards.
Pneumatic Efficient Drive: Equipped with a stable pneumatic actuator, with a response speed of ≤ 3 seconds, it can achieve remote automated control, suitable for industrial automated production lines, centralized control systems of sewage treatment plants, etc., reducing the intensity of manual operation and improving operation efficiency.
Anti-blockage and Easy Maintenance: The direct-through flow channel design + the non-sticking characteristic of polyurethane material can reduce sediment accumulation and blockage in the valve body; The valve structure is simple, and disassembly and maintenance are convenient, daily maintenance only requires simple cleaning of the sealing surface, reducing the difficulty of operation.
3. Application Scenarios and Industry Compatibility
Core Application Scenarios: Specifically designed for sewage sediment treatment, widely applicable in sewage treatment plants (settling tanks, sludge dewatering systems), river dredging projects, mine tailings transportation, construction pile foundation treatment, municipal sewage pipelines, etc., transportation systems containing high-impurity and high-wear media.
Compatible Scenarios: It can also be used in industries such as chemical and food processing, for liquid transportation control with a small amount of solid particles (requires confirmation of compatibility with the polyurethane medium), achieving precise diversion and control.
4. Quality Assurance and Usage Suggestions
The product complies with national industrial valve manufacturing standards. The pneumatic actuator selects high-quality cylinders and control components to ensure long-term stable operation; It undergoes pressure testing, sealing performance testing, and wear resistance simulation testing before leaving the factory, and can only be released for sale after passing the tests.
Usage Suggestions: Select the appropriate diameter and pressure grade based on the actual particle size of the medium and pressure parameters; Regularly check the pressure of the pneumatic system and the wear condition of the polyurethane sealing components, and promptly maintain if there are abnormalities, which can further extend the service life of the valve.
