The Important Functions of Steam Trap Valves
The Important Functions of Steam Trap Valves
2024-04-17

A steam trap valve is a device designed on devices that require steam, which can automatically discharge condensate, air, and non condensable gases from the steam system and prevent steam from being discharged. Important Functions (1) Able to quickly remove condensate generated; (2) Prevent steam leakage; (3) Remove air and other non condensable gases. The necessity of using steam equipment to remove condensate and air: (1) Prevent water hammer: If there is condensate in the steam pipeline, it will be strongly impacted by the high-speed flowing steam on the pipe wall, valves, and steam equipment, causing damage or damage to the pipeline bends, valves, and steam equipment. (2) To prevent a decrease in the efficiency of steam using equipment: Steam using equipment (especially indirect heating devices) is aimed at effectively utilizing the latent heat of steam. Excessive condensate trapped in these devices comes into contact with the heating surface, reducing the heating area and uneven heating up and down, resulting in a significant decrease in equipment efficiency. (3) Prevent corrosion of steam inside equipment: Oxygen in water and air coming into contact with the equipment can cause chemical reactions, leading to rust corrosion. (4) Prevent damage to steam using equipment: Due to the different temperatures of steam and water, the condensed water inside the equipment generates temperature differences locally, causing temperature difference stress and equipment damage. Specific requirements for steam trap valves: (1) No steam leakage during the discharge of condensate; (2) It can eliminate all condensed water from any part of the steam system; (3) Capable of simultaneously discharging air and condensate; (4) Suitable for a wide range of pressures; (5) Easy to repair and maintain: simple structure with few moving parts; (6) High practicality: small size, light weight, long lifespan, low price, and no loss of emission capacity due to air and steam.

How to Prevent Damage to the Sealing Surface of High-pressure Ball Valves?
How to Prevent Damage to the Sealing Surface of High-pressure Ball Valves?
2024-04-12

In industrial production, high-pressure ball valves play a crucial role, and damage to the sealing surface may lead to leakage and performance degradation. Therefore, measures must be taken to prevent and protect the sealing surface. 1. Proper Operation and Usage When operating high-pressure ball valves, it is essential to follow the correct operating procedures and technical requirements. Do not exceed the rated pressure and temperature range of the valve. Avoid over-tightening the valve to prevent damage to the sealing surface or premature wear. 2. Regular Inspection and Maintenance Regularly inspect the sealing surface of the ball valve, especially valves exposed to high-pressure and high-temperature environments. Remove any debris and dirt around the valve to ensure the sealing surface is in good working condition. 3. Select Appropriate Sealing Materials Choose suitable sealing materials according to the requirements of the working environment. For instance, in high-temperature or chemically corrosive environments, select sealing materials that are resistant to high temperatures and corrosion. Regularly inspect the wear and aging of sealing materials and promptly replace damaged seals. 4. Preventing Foreign Object Intrusion Install filters or screens to prevent foreign objects from entering the valve body and damaging the sealing surface. Avoid conducting messy operations around high-pressure ball valves to reduce the intrusion of external impurities. 5. Timely Repair and Replacement If damage or wear is found on the sealing surface, stop using it immediately and proceed with repairing or replacing the seals to prevent leaks from causing more serious issues. 6. Training and Education Provide training to operators to ensure they understand the working principles and proper operation methods of high-pressure ball valves, reducing the risk of seal surface damage due to operational errors. 7. Minimize Frequent Opening and Closing Reduce the frequency of opening and closing high-pressure ball valves because frequent operation increases wear and fatigue on the sealing surface, leading to premature failure. Where possible, take measures to minimize valve cycling, such as planning production schedules rationally or employing automated control systems. 8. Regular Cleaning and Maintenance Perform regular cleaning and maintenance on high-pressure ball valves to remove accumulated dirt and deposits inside the valve body, ensuring the valve operates smoothly and the sealing surface remains clean. Regular cleaning effectively reduces contamination and corrosion of the sealing surface, extending the lifespan of the seals. 9. Choose High-Quality Ball Valves Select high-quality high-pressure ball valve products to ensure that the design and manufacturing quality of the valves meet standard requirements and possess excellent performance and reliable sealing capabilities. Valves from DERVOS typically offer longer lifespan and better sealing effects, effectively...
