Test module comprises the testing valve flange 17,18,19 and the vent valve 20 of a plurality of different sizes that can be connected with the tested safety valve of different size, and vent valve 20 links together with testing valve flange 17,18,19; Vent valve 20 is connected with control module with vapour-liquid supercharging module.
Vapour-liquid supercharging module comprises water storage box 9 and pneumatic reciprocating hydraulic pump 22; Water storage box 9 is connected with the medium inlet of pneumatic reciprocating hydraulic pump 22 with vapour-liquid supercharging module filter 11 by vapour-liquid supercharging module stop valve 10; The media outlet of pneumatic reciprocating hydraulic pump 22 is connected with control module by pressure transducer 14; The media outlet of pneumatic reciprocating hydraulic pump 22 is connected with control module by vapour-liquid supercharging module solenoid valve 15 and testing valve flange 17,18,19, vent valve 20; Between vapour-liquid supercharging module solenoid valve 15 and testing valve flange 17,18,19, bleeder valve 21 is installed.At the media outlet place of pneumatic reciprocating hydraulic pump 22 rearmounted tensimeter 12 and rearmounted safety valve 13 are installed.
The pressurized air supplying module comprises air compressor machine 8; Air compressor machine 8 is connected with the air in of pneumatic reciprocating hydraulic pump 22 with pressurized air supplying module solenoid valve 7 by preposition stop valve 1, pressurized air supplying module filter 2, rearmounted stop valve 5, flow speed control valve 6; Flow speed control valve 6 is connected with control module with pressurized air supplying module solenoid valve 7; Air compressor machine 8 is connected with control module.Preposition safety valve 4 and preposition tensimeter 3 are installed between pressurized air supplying module filter 2 and rearmounted stop valve 5.
Control module can be made up of main frame and operator's console.Display module can be made up of the main frame with signal processing function and display or printer, and display module can be connected with sensor 14, and its signal is handled.
The course of work of vessel safety valve testing device is as follows: tested safety valve is connected on testing valve flange 17,18 or 19, control module is sent signal and is opened vapour-liquid supercharging module solenoid valve 15, vent valve 20 and pressurized air supplying module solenoid valve 7, regulate flow speed control valve 6 according to the test needs, pressurized air is from air compressor machine 8, arrive pneumatic reciprocating hydraulic pump 22 through preposition stop valve 1, pressurized air supplying module filter 2, rearmounted stop valve 5, flow speed control valve 6 and pressurized air supplying module solenoid valve 7, promote pneumatic reciprocating hydraulic pump 22 work; At this moment, can see compressed-air actuated pressure from preposition tensimeter 3, if compressed air pressure causes air pressure too high for a certain reason, when going beyond the limit of, preposition safety valve 4 meeting take-off pressure releases, the safety of protection system.
When pneumatic reciprocating hydraulic pump 22 is worked, with test(ing) medium water from water tank 9, be pumped in the pneumatic reciprocating hydraulic pump 22 through vapour-liquid supercharging module stop valve 10 and vapour-liquid supercharging module filter 11, and the media outlet of the pneumatic reciprocating hydraulic pump 22 of process, get rid of by vapour-liquid supercharging module solenoid valve 15 and vent valve 20, thereby the air in the whole liquid system is discharged, and control module is sent signal at stop vent valve 20.
