I. Cause Analysis
The main causes of gate valve internal leakage include the following:
Sealing Material Damage: The sealing material of the gate valve is the primary sealing component, commonly including rubber, plastic, and metal. Over time, these materials experience wear, aging, or decomposition, leading to internal leakage.
Improper Operation: The gate valve requires significant force for opening and closing. Improper operation can cause distortion or deformation of sealing components, compromising sealing performance.
Unreasonable Structural Design: Some gate valves have poorly designed structures, such as excessive sealing surface gaps or improper elastic designs, which may result in internal leakage.
II. Treatment Methods
To address gate valve internal leakage, the following solutions can be adopted:
Replace Sealing Materials: When internal leakage occurs, inspect the gate valve for aging or damaged sealing materials. Replace them promptly to ensure sealing performance.
Adjust Operating Methods: Operate the gate valve correctly, avoiding excessive force during opening and closing. Adjust the lever length to reduce operational difficulty and prevent internal leakage.
Choose Reasonable Structural Designs: When selecting gate valves, opt for products with well-designed structures, such as small sealing surface gaps and proper elastic designs, to avoid internal leakage.
Enhance Maintenance Management: Regularly inspect the sealing performance of gate valves and replace or repair sealing materials as needed.
