The hydraulic pressure holding valve test bench is a specialized equipment for performance inspection and testing of flange valves, developed in accordance with the national standard GB/T 13927-2008 “Industrial Valve Pressure Test”, the mechanical industry standard JB/T 9092-99 “Valve Inspection and Testing”, and the American Petroleum Institute standard API 598 (9th edition 2009.9), relying on the Fluid Machinery Research Institute of Shanghai University of Technology.
The equipment mainly consists of hydraulic system, mechanical system, electrical system, and pipeline system. It can perform upper sealing test, shell test, and sealing test on valves within a large range of valve specifications and pressure without any additional external force.
This equipment integrates mechanical transmission, hydraulic transmission, and electrical automatic control, with complete functions, easy and flexible operation, stable and reliable performance, high degree of automation, greatly improving production efficiency and reducing labor intensity. It is an ideal preferred equipment for valve manufacturing, use, and maintenance enterprises.
◆It is suitable to have a shell test, closure test and back seal test for flanged end valves;
◆No external force affects a testing valve as clamp hold flange
◆Valve can be turned to 90°to have a test(2 turning tables on option) so that it is convenient to carry out air seal test;
◆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 clamping has safety interlock with water pressure discharge;
◆Customer can choose the functions as followed: Double turn over;Safety door; Touch screen monitoringsystem;One key automatic monitor system(touch screen computer+ PLC)
