The vertical oil cylinder valve test bench is a valve performance testing equipment that adopts a vertical layout and uses hydraulic oil cylinders as the core power source. It uses vertically installed oil cylinders to apply pressure from top to bottom, achieving rapid clamping and sealing of valves, and conducting shell strength tests and sealing performance tests. This structure is particularly suitable for rapid and batch testing of flange connected valves, and is widely used in valve manufacturing, testing, and maintenance due to its small footprint, ergonomic operation, and high degree of automation.
Using high-quality square steel or steel plate welding, the structure is compact and stable, with strong load-bearing capacity and high vertical guidance accuracy, ensuring no unbalanced load when the oil cylinder is pressed down. One of the most significant advantages of vertical structures is their small footprint.
◆It is specially suitable for have a test for small sized flanged end valves, welded end or threaded valves;The upper pressing device has hydraulic driving and screw driving type;
◆An control system controls 1-6 valve test stations(on customer request);
◆It is equipped a claw press device and claw hold device and has wide suitability;
◆A top beam can be turned over 90°and the work table is fully open so that it is easy to operate;
◆Test medium is water or air(6 bar gas source supplied by customer,test medium water can be recycling), can bechanged over by pipeline control valve;
◆Equipped LP water filling、 HP water filling and pressure-keeping & timing auto-control system;
◆Equipped automatic oil pressure discharge system, when being ready state, system discharge automatically, whenworking, system return to normal status to effectively reduce oil temperature, elongate life of the test bench andsave energy;
◆Hydraulic or screw clamping、 pressing device has safety interlock with water pressure discharge;
◆Customer can choose the functions as followed:Touch screen computer monitoring system;Safety door;Multi-station.
