 *Computercontrolled valve constant pressure test machine

Technical Features
(1)It is used pneumatic or hydraulic to clamp device, the clamping force is adjustable, and with a pressure gauge shows the corresponding clamping force, provide pressure and clamping force table, easy to check the pressure relief valve and path for the operator to choice suitable clamping force.
(2) Gas test: 0.*0.8MPa air is used to test after pressurizing by gas booster, air pressure of output is adjusted by adjusting the air pressure
（3）Testing procedure is the automatic control system, it fill high pressure gas in the valve measured, when it reaches the set  pressure and relief valve  open, and then relief valve passed judgment, otherwise unqualified;
(4) the measured pressure relief valve be set to manual operation, manual adjust and open the valve measured pressure;  
(5)be used by computercontrolled system ,that can be set in The specified range;  
(6)It is used by the U.S. NI company Labveiw, it can dynamic display and automatic record time pressure curve of relief valve, and can print calibration reports and calibration curves directly;
(7) booster is our company independent production, its internal seals are imported;
(8) valves, pipe fittings and joints be used are all madeby stainless steel;
(9) with a test fixture according for customer requirements testing.
(*0)It can automatically stop and alarm buzzer if leakage or pressure is too high during the test;
(*1)A panic on the testbed can stop the test immediately if unexpected events happen.
 

Intelligent calibration and control system
1、It is intelligent controlled in the check process, and automation controlled on the setting pressure;
2、 It can be mounted with the marking machine, scanners, bar code and qr code with the corresponding matching check valve, for followup work;
3、Automatic printing relief valve check orders, the safety valve calibration report, check bills, such as layout format  which can be customized according to customer's requestï¼›
4、It can realize remote audit, issue, check, etc., relevant personnel can get related test realtime testing data in ; calibration process
