How Should Different Types of Gate Valves be Maintained Daily?
Gate valves are essential shut-off devices in industrial piping systems. Their reliability and lifespan are directly related to the safety and stability of the entire system. They can be categorized into various types based on their structure (such as gate disc design and stem movement), and their daily maintenance priorities vary. WEIZIDOM, based on years of industry experience, has summarized the following key maintenance points for different types of gate valves. Different Gate Valves Parallel gate valves have two parallel plates, which rely on medium pressure to achieve a seal. During routine maintenance, focus on checking for gate sticking and wear on the sealing surfaces. Regular cleaning of the gate disc groove is recommended to prevent impurity accumulation that may affect the sealing effect. For double-disc gate valves, check for failure of the intermediate spring. Wedge-type gate valves achieve sealing through the wedge-shaped action between the gate disc and the valve seat. During maintenance, pay special attention to wear on the sealing surfaces and regularly check for changes in the wedge angle. Single-disc wedge valves require attention to potential seizures caused by thermal deformation; double-disc gate valves require checking the flexibility of the hinge mechanism. ...
