leak test equipment
for water valves
|
Water valves with diameters of 20-100mm can
be leak tested both internally and externally using the:
'differential pressure with water'
technique.The features of the machine include
easily removable tools for the variable diameters of valves and torque control for
closing the valve, and rotation control at opening and closing of the valve. The control
panel is accessible, with a keyboard for the setting of parameters, such as programmes,
times, alarm points and pressures. The display indicates the test process, pressures and a
test result in pascals. A separate pump stand allows access for maintenance.The
measurement pneumatic equipment is contained within a separate enclosure. |

| There is a pressure tank and return water
tank with requisite filters and valves included, and a sugevac vaccum pump for vaccum
pumping of the valve before filling with water, which provides a high filling rate and
eliminates the fill time before pressure stabilisation. the maximum external test pressure
is 25 bar. A drip tray is placed under the fixture to collect waste water and at the
lowest point, there is a pump for the evacuation of waste water. Safety
Upon activation of the start button, the valve is
automatically loaded and the protective guard descends, and automatically locks. The guard
may be opened after the test pressure has been reached to allow for visual leak location.
The machine is equipped with clear protective guards and safety switches on three sides to
allow for valve maintenance and filter exchange. |
