The first, exhaust performance when mensuration air inlet and exhaust valve aqueous vapor is alternate, is arranged on tested air inlet and exhaust valve on left test board.
Closedown decompression constant pressure valve, vacuum breaker, air intake control valve, left aqueous vapor share control valve, right aqueous vapor share control valve and water inlet control valve.
1. by water inlet pipe to water filling in gas storage water tank, water injection rate is about tank body 1/4 volume.
2. inflate in gas storage water tank by inlet pipe again, make air pressure in tank reach 0.4 ~ 0.5MPa.
3. adjustment decompression constant pressure valve top hole pressure is 0.05 ~ 0.10MPa.
4. open vacuum breaker successively, air intake control valve, left aqueous vapor share control valve, the inflation of the tested valve on test board to the left, check whether the big venting port of tested valve is vented.
5. while opening water inlet control valve, then close air intake control valve gradually, opening-closing valve action is wanted stable and continuous, is mutually coordinated, ensure that tested valve inlet pressure gauge indicates within the scope of 0.03 ~ 0.05MPa, like this to water-filling in tested valve, check whether the big venting port of tested valve closes.
6. again opening air intake control valve, close water inlet control valve simultaneously, and open draining control valve gradually, opening-closing valve action is wanted stable and continuous, is mutually coordinated, and ensures that tested valve intake pressure tabular value is within the scope of 0.03 ~ 0.05MPa.
Now, in tested valve, the water surface declines gradually, and gas is full of valve body gradually, and the big venting port of tested valve can open exhaust automatically, can think this tested valve have aqueous vapor alternate time a large amount of degassing function automatically.
Tested valve intake pressure tabular value is within the scope of 0.03 ~ 0.05MPa, and the water surface can drop to the left liquidometer top below tested valve or can see the water surface from left liquidometer.
If big venting port can not open exhaust automatically, then can judge that this air inlet and exhaust valve does not have a large amount of degassing function when aqueous vapor is alternate.
(note: when the alternate a large amount of exhaust of aqueous vapor, owing to gas velocity is very fast, be the sub-light velocity, it is possible to water droplet in general, the air inlet and exhaust valve with slow closure function also may water outlet on a small quantity, but the water outlet time should more than 1 minute).
(left liquidometer is in the process as auxiliary observation equipment).
7., 4. ~ process 6. carry out altogether three times, according to three test results judge tested valve whether have aqueous vapor alternate time a large amount of degassing function automatically.
2nd, measure the balling-up pressure of air inlet and exhaust valve when a large amount of exhaust, now air inlet and exhaust valve is arranged on right test board.
1. water in emptying gas storage water tank.
2. open air intake control valve, inflate in gas storage water tank with air compressor, make tank body atmospheric pressure reach 0.4 ~ 0.5MPa.
3. decompression constant pressure valve top hole pressure of adjusting is respectively 0.02MPa, 0.06MPa, 0.12MPa, 0.4MPa.
4. keep left aqueous vapor to share control valve to close, open right aqueous vapor fast and share control valve, check the tested valve ball float on right test board reads tested valve inlet pressure gauge numerical value while whether being blown afloat, tentatively determine balling-up pressure from 0.02MPa, 0.06MPa, 0.12MPa, 0.4MPa.
5. repeat 2. ~ 4. process twice again with the balling-up pressure tentatively determined in 4., observe and determine whether the ball float of tested valve can be repeated to blow afloat on this pressure stage and can be defined as corresponding balling-up pressure.
3rd, air inlet and exhaust valve measures with or without air suction function, and now tested valve is arranged on left test board.
1. water in emptying gas storage water tank.
2. close air intake control valve, water inlet control valve, draining control valve, open left and right aqueous vapor and share control valve.
3. bleed with vacuum pump, make to open rapidly water inlet control valve when producing certain negative pressure value (-0.035 ~-0.030MPa) in gas storage water tank, now observe whether tested valve can open air-breathing.
Its advantage is:
Can measure air inlet and exhaust valve aqueous vapor alternate time exhaust performance, balling-up pressure when a large amount of exhaust, with or without performance tests such as air suction functions, structure simple operations is convenient, have and wide apply future.
