The tilting disc check valve is a common type of valve used in pipeline systems to prevent reverse flow of the medium. It typically consists of components such as the valve body, disc, spring, and sealing gasket. The working principle of the tilting disc check valve is based on the design of the disc: the disc is positioned at an angle, allowing the medium to flow smoothly through the valve in the forward direction, while swiftly closing the valve in the event of reverse flow, thereby preventing backflow of the medium. One of the characteristics of the tilting disc check valve is its simple structure. Due to the fewer components and compact layout, manufacturing and maintenance are relatively easy. Additionally, the tilting disc check valve has the capability of quick closure. When there is a change in the flow direction of the medium, the disc promptly responds and closes the valve, effectively preventing backflow of the medium and maintaining the normal operation of the pipeline system. Another significant feature is its excellent sealing performance. The tilting disc check valve employs devices such as springs to assist in closing the disc, ensuring effective sealing of the valve in the closed position, thus preventing medium leakage and safeguarding the safe operation of the pipeline system. Furthermore, tilting disc check valves are typically manufactured using corrosion-resistant materials, enabling them to operate stably in corrosive media over the long term. Another notable feature of the tilting disc check valve is its wide range of applications. It is suitable for various media, including liquids, gases, and steam, and is widely used in industries such as water supply, drainage, chemical, and petroleum. Whether in low-pressure systems or high-pressure systems, tilting disc check valves can reliably prevent medium backflow, protecting the safety operation of pipelines and equipment. In summary, the tilting disc check valve plays a crucial role in pipeline systems due to its characteristics of simple structure, rapid closure, excellent sealing performance, corrosion resistance, and wide applicability. When designing and selecting valves, considering factors such as the working pressure of the pipeline system, characteristics of the medium, and operating environment, choosing the appropriate tilting disc check valve can effectively enhance the safety and stability of the pipeline system.

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.
