Resolving Improper Closure in Industrial Check Valves
Apr 15, 2024
In the course of industrial operations, machinery often encounters various challenges over time. One such issue is the improper closure of check valves, which plays a critical role in ensuring the smooth operation and safety of industrial processes. This article delves into the common causes of improper check valve closure and presents effective solutions to mitigate these issues.
Factors for Improper Closure in Check Valves
Improper closure in check valves, crucial for blocking backflow in pipelines, can result from various factors. Dive into the details, and you'll find these common problems.
1. Corrosion of External Thread on Valve Seat
Over time, the external threads on valve seats may corrode or oxidize, resulting in increased friction that hinders the smooth rotation of the valve. This corrosion adversely affects the proper functioning of the check valve.
2. Poor Connection between Valve Seat and Piston Valve
Inadequate connection between the valve seat and piston valve can cause misalignment, preventing them from securely contacting each other. As a consequence, the sealing performance of the check valve is compromised.
3. Damage to Valve Seat Sealing Surface
The sealing surface of the valve seat is crucial for preventing media leakage. Any damage to this surface, whether due to improper operation or external factors, can lead to leakage and compromise operational safety.
4. Accumulation of Residues
Residues and debris accumulation between the check valve base and the valve disc may occur due to impurities present in the media or insufficient cleaning over time. These residues impede the proper closure of the valve, potentially resulting in leakage.

Proposed Solutions
To address the issue of improper closure in industrial check valves, the following measures can be implemented.
Regular Maintenance
Implementing routine maintenance practices such as cleaning the valve surfaces and applying appropriate rust inhibitors can effectively prevent corrosion of external threads on valve seats, thereby prolonging the valve's lifespan.
Improved Connection Methods
Enhancing the connection between the valve seat and piston valve or utilizing more reliable connectors ensures a secure and stable connection, minimizing misalignment issues that affect sealing performance.
Timely Replacement of Damaged Components
Prompt replacement of damaged valve seat sealing surfaces is essential to maintain proper sealing performance and prevent media leakage. Additionally, regular inspection and replacement of worn sealing components are necessary to prevent leaks.
Enhanced Cleaning Procedures
Implementing stricter media filtration measures and conducting periodic cleaning of accumulated residues between the check valve base and valve disc help maintain valve functionality and prevent improper closure due to debris buildup.
