YFB-6A valve test bench

​  

Horizontal claw clamping 6A test bench


Technical performance and feature

● It is suitable to have a test for flange end 6A valves;
● No external force affects the testing valve since the clamping is completed via holding the flange by claws:
● Valve can be turned to 90° to have a test, test media is water (water is recyclable);
● 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, when working, system return to normal status to effectively reduce oil temperature, elongate life of the test bench and save energy;
● Hydraulic clamping has safety interlock with water pressure discharge;
● Customer can choose the functions as followed: Safety door; Touch screen computer monitoring system.



Vertical 6A test bench

Vertical test bench can be designed as screw pressing or hydraulic pressing type.


Technical performance and feature
 
● It is suitable to have a test for flanged end or welded groove 6A valves;
● Hydraulic vertical type: the upper part equips top press oil cylinder, the lower part equips claw holding oil cylinder;
● Screw vertical type: the upper part equips top pressure screw;
● Test media is water (water can be recycling), equipped LP water filling, HP water filling and pressure-keeping & timing auto-control system;
Hydraulic vertical type: equipped with automatic oil pressure discharge system, when being ready state, system discharge automatically when working, system return to normal status to effectively reduce oil temperature, elongate life of the test bench and save energy;
Top screw type: suitable to test inner tunnel sealing valves, if a customer selects plane or welded groove sealing valves, customer need to choose bootstrap tank system1;
● Hydraulic clamping (or screw tightening) has safety interlock with water pressure discharge;
●  Customer can choose the functions as followed:  Safety door; Touch screen computer monitoring system.

Note 1:Top press screw valve test bench is suitable for inner tunnel sealing type valves, if you need to test plane flanged sealing valves and welded groove valves,you need to choose“bootstrap tank system".“Bootstrap tank”systems made up of terraced stepped cylinder and piston, blind flange is equipped at the end of piston. When testing valve, pre-top press “bootstrap tank" (blind flange) at the end of valve, fill test medium in the body of valve,"bootstrap tank" will generate thrust to push blind flange at the end of valve to achieve sealing effect according to a certain magnification and test medium pressure. Since the thrust of "bootstrap tank" system varies with test medium pressure, when testing net extrusion pressure·the valve is the difference between thrust of 'bootstrap tank" system and valve test medium force, the difference ls very small.almost no force affects testing valve.
