  • Gain a Deeper Understanding of Buried Soft-seated Gate Valves
    Gain a Deeper Understanding of Buried Soft-seated Gate Valves
    2024-05-14

    Buried soft-seated gate valves are critical valves widely employed in pipeline systems, featuring unique designs and functionalities that render them extensively utilized across various industrial and domestic applications. Working principle The working principle of buried soft-seated gate valves is based on the sealing performance between the gate and the sealing surface. When the valve is in the closed position, the gate is pushed against the sealing surface by the actuating mechanism, typically a handwheel or electric actuator, achieving complete closure of the pipeline. When it is necessary to open the valve, the actuating mechanism pulls the gate away from the sealing surface, allowing the medium to flow freely in the pipeline. Structural characteristics 1. Subterranean Design: Buried soft-seated gate valves are typically installed underground within pipeline systems to shield the valves from external environmental impacts. Simultaneously, this design maximizes space conservation and ensures unobstructed pipeline flow. 2. Soft-Sealing Structure: Soft-sealing materials typically utilize rubber or polymers, offering excellent sealing performance and corrosion resistance. They can maintain a stable sealing effect across various media and temperatures. 3. High Pressure Endurance: The design structure of buried soft-seated gate valves is robust, capable of withstanding high pressure and impact forces, ensuring stable and reliable operation under various operating conditions. 4. Anti-corrosion Coating: Valves are typically coated with anti-corrosion coatings on their surfaces to enhance durability and lifespan, thereby reducing maintenance costs. 5. Complete Accessory Configuration: Buried soft-seated gate valves are typically equipped with accessories such as handwheels, electric actuators, limit switches, etc., to meet operational requirements under different conditions. Application area 1. Petroleum and Chemical Industry: Used for control and regulation of crude oil, natural gas, and chemical media. 2. Municipal Water Treatment Systems: Used for flow control and prevention of backflow in municipal water distribution networks. 3. Wastewater Treatment Plants: Used for drainage and regulation in wastewater treatment systems. 4. Thermal Power Plants: Used for flow control in boiler feedwater pipelines and cooling water systems. 5. Urban Heating Systems: Used for regulation and control of heat transfer media in centralized heating networks. Buried soft-seated gate valves play a crucial role as integral components in pipeline systems across industrial and civilian domains.

  • What is a Tilting Disc Check Valve?
    What is a Tilting Disc Check Valve?
    2024-05-08

    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.

This served as a compelling testament to the quality and popularity of our products. Additionally, we added a touch of cultural charm to the exhibition by offering two exquisite refrigerator magnets as special gifts for our valued clients. These magnets beautifully combined iconic symbols - one featuring the majestic Palace Museum paired with adorable panda, and the other portraying the splendid Saint Basil's Cathedral alongside the graceful Russian Bear. These unique and visually captivating magnets garnered immense attention at the exhibition. Here are the key features of these two products: Fully Welded Ball Valve: This product is celebrated for its excellent sealing and fully welded design. It finds applications across various industrial sectors, including petroleum, natural gas, chemical, and energy industries. Clients unanimously expressed that the exceptional performance and reliability of the Fully Welded Ball Valve make it their top choice. Line Blind Valve: DERVOS's Line Blind Valve also garnered significant attention at the exhibition. Renowned for its swift transition, economical solution and tool-less handling, this product is widely used in pipeline systems when there is a need for either complete closure or unimpeded flow transition without a significant drop in pressure. DERVOS remains committed to delivering high-quality valve products and excellent service to our clients. We extend our gratitude to every client who visited our booth during PCVExpo 2023 and look forward to building long-term partnerships with them.
