Product DescriptionSliding Type Quick Action Line BlindThe new line blind for pipelines, developed by henan quanshun flow control science & technology co., ltd., features a unique clamping mechanism. Utilizing the principle of spiral transmission, it employs a single locking device instead of the traditional three-point locking system. This allows for the switching of the valve plate without the need to expand the pipeline, resulting in higher efficiency, reduced size, lighter weight, and smoother, more convenient, and quicker operation. it is suitable for use in industries such as petroleum, chemicals, steel, and can be applied to feed pipelines in equipment, transfer storage/pumping station pipelines, reactor feed pipelines, gas pipelines in metallurgical blast furnace systems, flare systems. And more, the line blind serves as a reliable cut-off device, playing a critical role in equipment maintenance, pipeline switching, media isolation, preventing media leakage, protecting personnel safety, and reducing environmental pollution. Additionally, it can be applied in various complex industrial and mining conditions involving water, gas (steam, air, natural gas, etc.), petroleum refining, oil products, metallurgical slag, slurry, granular media, dust media and multiphase flow.1. the line blind utilizes a unique and simple switching mechanism, allowing one person to easily, quickly, and safely stop or operate the pipeline without the need for any tools or lifting equipment.2. the valve plate can be switched open or closed without expanding the pipeline.3. when in the closed position, no liquid or gas medium can leak downward, ensuring 100% safety isolation with zero leakage.4. the line blind can be easily and safely operated by a single person without the need for special training.5. no special tools are required; simply turn the handwheel, then swing or slide the valve plate to achieve pipeline interception or cut-off, eliminating the need for heavy mechanical tools like cranes.6. using the line blind for isolation reduces worker labor intensity, requires fewer pipeline operators, and presents no danger.7. a safety locking device is added to the handwheel operation position to prevent operator errors that could lead to accidents, ensuring safety.8. the valve is compact, lightweight, with a simple and reliable structure, making maintenance easy.9. the flow channel is designed with a full-bore structure, allowing for zero flow resistance.Technical SpecificationsValve Size2''~36''Valve PressureClass 150-900Valve Body MaterialStainless Steel 304/316 WCBSeal RingFKM/FFKMWorking temperature-40~327oCOther TypesSwing typeNon spill typeCompact typeIt take within 2 minutes for one operator to blank a line, operating the handwheel and rotating the bind intoplace, without line spreading. Again, all inline movement isinternal, elminating the potential for pipe-joint stress.Non spill type of Line Blind has good advantages in Oilterminal & offshore applications where is limited in stallation space and marine pollution is strictly prohibited.The three sides covered body & compact design prevents ground pollution and it allows to installat parallel pipe lines.The Compact type is designed for replacement of existing valves, limited F-F dimension or large diameter pipeline applications or limited space for installation.lt is designed with a short face to face, and has tapped bolt holes for easy installation between flanges.The compact design also reduces weight and requirement for extra pipe support.Drawings & DimensionsOur engineering team can provide tailored designs to meet specific project requirements.Company ProfileFAQQ: Why choose our quick action line blind?A: Quanshun Quick Line Blinds Offer a combination of two essential criteria--Zero Leakage and Safe & Easy blinding by untrained one operator.Q: Advantages compared with traditional line blind valve?A: 1.No line spread: The unique & simple Gear-set mechanism makes a gap to switch blind plate without line spreading2.Auto positioning of blind plate: Blind plate is set on correct position by positioner3.Hand wheel torque indicator: Torque indicator provides correct positioning of tightening untightening operation4.Safety locking: Locking devices with Pad Lock with key secure safety from incorrect operation by unauthorized operator5.Self stick free mechanism: Unique gear set mechanism shall free the blind plate from sticking problem6.Gasket protection cover: Blind cover protects blind plate from external damages7.Double Sealing (optional): Depend on media and operating conditions, seal ring can be placed in double for safety8.Open/Close position sensor(optional): Sensors can be installed to indicate blind plate positionQ: What causes leakage at the valve and pipe connection?A: First, the sealing surface is damaged or contaminated by dirt; Second, gasket failure; Third, the pipe flange pressure is uneven or not pressed.Q: Can the valve actuator adjust itself?A: The valve actuator has been debutted before leaving the factory, and non-professional personnel are forbidden to adjust.
