1.JLT-valve test bench(Valve testing equipment) Technical performance and feature
● It's suitable for the pressure performance test of the flange type, welding type, internal and external thread type valves
., fully meet the GB/T 13927-2008, JB/T 9092-99, the API 598 requirements.
● It has the grip pressure hold and top press clamp type operation. The upper square horizontal frame can push to
turn rear 90° function, with the simple operation and use.
● The system equips with the high and low pressure water pump device to be used for the test medium circulation storage.
● The pressure trial medium is water, air and kerosene that can be selected freely by users.
● During the course of presseure protection of water or air test, any button can not work under the condition of which
the tested valve cavity has high pressure, it can work nornmally until leaking the pressure to
nopressure (make sure safety while working).
● The test bench is equipped with an automatic oil pressure discharge system. As it is used, a high pressure condition
and pressure discharge condition can be changed over to effectively reduce the oil temperature, elongate life
of the test bench and save energy.
● It sets the pressure trial safe protective device.
● It can match with computer detection data management system.
