When installing flanged check valves, the following precautions should be taken to ensure their proper operation and long-term use: 1. Preparation before Installation Inspect the valve: Ensure that the valve has not been damaged during transportation and that there are no foreign objects inside the valve body. Clean the pipeline: Clean debris such as weld slag and rust from inside the pipeline to prevent them from entering the valve body. Verify parameters: Check the pressure, temperature, material, and other parameters on the valve's nameplate to ensure they meet the requirements of the working conditions. 2. Installation Position and Direction Flow direction marking: Ensure that the arrow marking on the valve is consistent with the flow direction of the medium in the pipeline. Vertical installation: Check valves are typically installed vertically, with the valve disc free to open and close. When installed horizontally, ensure that the valve disc can move freely. 3. Flange Connection Align flanges: Ensure that the flanges of the pipeline and valve are aligned to avoid offset or stress concentration. Flange gasket: Select the appropriate gasket material and place it correctly between the flanges to prevent leakage. Bolt tightening: Tighten the flange bolts uniformly in a diagonal sequence, gradually increasing the force to ensure uniform stress on the flange and prevent deformation. 4. Avoid Stress Pipeline support: Install appropriate supports before and after the valve to prevent the weight and stress of the pipeline from concentrating on the valve. Reduce vibration: In pipeline systems with significant vibration, take measures to reduce vibration transmission to the valve and extend its lifespan. 5. Testing and Commissioning Seal test: Conduct hydrostatic or pneumatic testing after installation to check the sealing performance of the flange connections and inside the valve. Function test: Confirm that the check valve can open and close normally during medium flow and stoppage. 6. Regular Maintenance Regular inspection: Regularly inspect the tightness and sealing performance of the flange connections to prevent loosening and leakage. Clean the valve body: Clean the inside of the valve body when necessary to prevent debris accumulation that could affect valve performance. Lubricate components: For check valves requiring lubrication, regularly inspect and add lubricant to ensure flexible valve disc movement. 7. Special Working Condition Considerations High temperature and pressure: In high-temperature and high-pressure conditions, select appropriate gasket and bolt materials to prevent leakage caused by thermal expansion and contraction or stress concentration. Corrosive media: For corrosive media, choose valves made of corrosion-resistant materials and implement corrosion prevention measures. 8. Environmental Requirements Protective measures: When installing in outdoor or corrosive environments, take protective measures for the valve, such as ap...

The Orbit Ball Valve, with its unique design and reliable performance, has been widely used in industrial fields such as oil, natural gas, and chemicals. 1. Structure of Orbit Ball Valve The structure design of the Orbit Ball Valve differs from that of a conventional ball valve. Its main components include: (1) Valve body: The body of the Orbit Ball Valve is typically made of forged or cast steel, offering high strength and corrosion resistance, and is capable of withstanding high-pressure and high-temperature environments. (2) Ball: The ball moves within the valve body through a specially designed track and is usually made of stainless steel or nickel-based alloys, providing excellent wear and corrosion resistance. (3) Seat: The seat is the part that comes into contact with the ball, typically made of metal to ensure sealing performance under high pressure and high temperature conditions. (4) Stem: The stem connects the ball to the actuator, responsible for transmitting operational torque to move the ball within the valve body. (5) Sealing System: This includes the seat seal and stem seal, ensuring no leakage of the medium. Seals are typically made of metal or high-performance polymer materials. (6) Actuator: This includes manual operation mechanisms or automated actuators used to control the opening and closing of the valve. 2. Working Principle of Orbit Ball Valve The working principle of an Orbit Ball Valve differs from that of a conventional ball valve, with its core function relying on the track movement and rotation of the ball within the valve body. The opening and closing process of an Orbit Ball Valve is as follows: Closed State: In the closed state, the sealing surface of the ball is tightly pressed against the valve seat, forming a reliable seal and preventing the flow of the medium. Opening Process: (1) Initial Eccentric Movement: When the actuator applies operational torque, the ball first moves eccentrically up or down along the track, gradually disengaging from the valve seat. This process reduces friction between the ball and the seat, preventing wear on the sealing surface. (2) Rotational Movement: After completing the eccentric movement, the ball continues to rotate 90 degrees, fully opening the passage and allowing the medium to flow smoothly through. As the ball's movement and rotation on the track occur in separate steps, the operation is smoother, and the required torque is lower. Closing Process: (1) Initial Rotational Movement: When the actuator operates in reverse, the ball first rotates 90 degrees to the closed position, thereby closing the passage. (2) Eccentric Movement: After the ball completes the rotation, it moves along the track back to the valve seat, forming a seal. This frictionless sealing process ensures high sealing performance and a long service life for the Orbit Ball Valve. 3. Advantages of Orbit Ball Valve (1) Frictionless Sealing: The eccentric and rotational movements of the Orbit Ball Valve are separ...

Y-type ball valves have gained popularity in industrial pipeline systems due to their unique Y-shaped structure and excellent fluid control performance. They are designed to reduce fluid resistance and improve flow efficiency, making them well-suited for specific applications. 1. Situations that require low flow resistance and high flow rates: ①High-flow pipeline systems: The Y-shaped design of the ball valve significantly reduces the resistance as fluid passes through the valve, making it suitable for pipelines that require high-flow control. This design ensures smooth and efficient fluid flow, reducing energy consumption. ②Applications with low pressure drop requirements: In systems sensitive to pressure drop, the low flow resistance characteristics of Y-type ball valves effectively reduce pressure losses in the system, ensuring overall pipeline efficiency. For example, in long-distance transportation pipelines and process flows that require specific pressure maintenance, Y-type ball valves are an ideal choice. 2. Handling high viscosity and media with particles: ①High-viscosity fluids: Y-type ball valves can handle high-viscosity fluids, avoiding excessive flow resistance within the valve. This makes them suitable for the transportation and control of high-viscosity media such as oils, syrups, and slurries. ②Media with particles: Due to their smooth and spacious flow passages, Y-type ball valves effectively prevent particle accumulation and blockages when handling fluids with particles. They are suitable for transporting media such as mud and wastewater. 3. Situations that require frequent operation and adjustment: ①High-frequency opening and closing operations: The design of Y-type ball valves allows them to perform well in frequent opening and closing operations, providing reliable sealing performance and long service life. In situations that require frequent operations, such as flow and direction control, Y-type ball valves are a reliable choice. ②Precise flow control: The flow passage design of Y-type ball valves enables precise flow control, making them suitable for process flows that require fine control of flow rates, such as chemical reactions and pharmaceutical production processes. 4. Installation environments with limited space: Y-type ball valves have a compact structure and occupy minimal space, making them suitable for installation in limited spaces. Whether it is inside equipment, dense pipeline areas, or systems that require high-density installation, Y-type ball valves can adapt flexibly. 5.
