The screw top pressure valve test bench adopts screw top pressure and valve channel sealing type for various tests of the valve. The test bench is composed of left and right memorial archway, middle memorial archway, pull rods, jacking screw nut pairs and driving devices, V-shaped support system, waterway system, electrical system, etc.
This experimental equipment has taken effective technical measures in heavy machinery design, valve testing, automatic control, and convenient operation.
The screw top pressure valve test represents a perfect combination of classic and practical valve testing equipment. It abandons complex control systems and reliably solves the problem of valve sealing testing with its most essential mechanical force. For users who do not require a high degree of automation but highly value equipment reliability, durability, and return on investment, the screw top pressure valve test bench is a timeless and wise choice.
◆Top cylinder valve test bench is suitable to have a test for various connection types of valves, we advise you equip”servo control system”
◆Top screw valve test bench is suitable to have a test for inner tunnel sealing valves, if a user selects plane orwelded groove sealing valves, you need to choose bootstrap tank system;
◆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 pressing device (top screw) has safety interlock with water pressure discharge;
◆Customer can choose the functions as followed: Touch screen computer monitoring system;Servo controlsystem; Bootstrap tank system.
