Embodiment
As depicted in figs. 1 and 2; The invention discloses a kind of automatic leakage tester of nozzle of TOP-TIP; It comprises a test board 1; Slidely connect a sliding seat 3 on said test board 1 length direction, be fixed with a holder 2 and one and eject cylinder 4, the said piston that ejects cylinder 4 is towards holder 2, said sliding seat 3, holder 2 and eject cylinder 4 should be on same axis; Said sliding seat 3 can move along the length direction of test board 1, carries out leak-testing with the nozzle that adapts to different length; Be fixed with an air inlet piece 5 on the said piston that ejects cylinder 4, said air inlet piece 5 is connected with a draft tube 6, and the other end of said draft tube 6 is connected with source of the gas 7, usually source of the gas 7 internal memory contain high pressure nitrogens; Be fixed with a sealed nozzle cover 8 on the said sliding seat 3, said sealed nozzle cover 8 is connected with one and detects tracheae 9, and an end of said detection tracheae 8 needs the intracavity inter-connection with sealed nozzle cover 8, and the other end of said detection tracheae 9 probes in the water tumbler 10.In water tumbler 10, inject a certain amount of water in advance, and probe into the port that detects tracheae 9 below the liquid level in the water tumbler 10.
As shown in Figure 3; Usually on a limit of sliding seat 3, a linear bearing 21 is set; On another limit of sliding seat 3, register pin 22 is set, on test board 1, be provided with simultaneously one with said sliding seat 3, holder 2 and the axis that ejects cylinder 4 places mutually equality lead rail axis 23 and one arrange equally distributed pilot hole 24 with lead rail axis 23 parallels, through cooperating of lead rail axis 23 and linear bearing 21; Can realize that sliding seat 3 moves along the length direction of test board 1; And after moving into place,, make sliding seat 3 location through cooperating of register pin 22 and pilot hole 24.
As shown in Figure 4; Said air inlet piece 5 has an air intake opening 31 and gas outlet 32 that is connected; Said air intake opening 31 is connected with draft tube 6; During concrete operations, be connected gas outlet 32 with the charging aperture 34 of nozzle 33, inject gases at high pressure from charging aperture 34 nozzle body 38 inner chambers of nozzle 33 through draft tube 6.
During concrete operations, at first regulate the position of sliding seat 3, the length of distance and nozzle 33 to be measured between sliding seat 3 and the holder 2 is complementary.Be placed on nozzle 33 between sliding seat 3 and the holder 2; And be placed on 34 ends of the charging aperture on the nozzle body 38 on the holder 2; Be placed on head of nozzle 35 ends of nozzle 33 in the sealed nozzle cover 8 on the sliding seat 3, and the inner chamber roof of discharging opening 36 and sealed nozzle cover 8 on the head of nozzle 35 is adjacent to, gases at high pressure can't be leaked from the discharging opening on the head of nozzle 35 36; For this reason, on the inner chamber roof of sealed nozzle cover 8, a rubber blanket 37 is set usually.Start and to eject cylinder 4, the gas outlet 32 on the air inlet piece 5 is adjacent to charging aperture 34 on the nozzle body 38 mutually.Open source of the gas 7 then; Gases at high pressure in the source of the gas 7 inject air inlet piece 5 successively through draft tube 6; And the charging aperture from the nozzle body 38 34 gets into the inner chamber of nozzle bodies 38; Because the discharging opening 33 on the head of nozzle 35 has been plugged, if head of nozzle 35 leaks with the connecting portion existence of nozzle body 38, the gas of leakage can be injected in the water tumbler 10 through the detection tracheae 9 that is connected with sealed nozzle cover 8; Operating personnel can have the bubble of denying to emerge through observing the detection tracheaes 9 in the water tumbler 10, can judge easily that the head of nozzle 35 and the connecting portion of nozzle body 38 have not existence to leak.After measuring the leakage situation of a nozzle 33, operation ejects cylinder 4, makes the piston retraction that ejects cylinder 4, drives air inlet piece 5 and retreats, and takes out the nozzle of having measured 33, can carry out the leak-testing of next nozzle 33.
For the ease of operation, the automatic leakage tester of the nozzle of TOP-TIP of the present invention can also comprise a control center 11, said draft tube 6, ejects cylinder 4 and control center's 11 control linkages.Operating personnel can eject and be retracted into line operate through what 11 pairs in control center ejected cylinder 4, the gas injection of inner chamber that also can be through 6 pairs of nozzle bodies 38 of 11 pairs of draft tube of control center with stop gas injection and operate.Except arranging switch, tensimeter 15 can also be set in the said control center 11, the pressure to draft tube 6 build-in test gases reads with the air pressure that ejects cylinder 4 respectively.Simultaneously, in the said control center 11 timetable 16 can also be set, respectively the delay time of supplying gas of test gas, supply gas dwell time and exhaust be read and monitored time delay.
For the automatic leakage tester of the nozzle that makes TOP-TIP of the present invention can all carry out leak-testing to the nozzle of different size; For this reason; As shown in Figure 5; Be removably connected with nozzle fixed block 12 respectively on the said holder 2 of the automatic leakage tester of nozzle of TOP-TIP of the present invention and the sliding seat 3, have nozzle pickup groove 13 on the said nozzle fixed block 12.Nozzle fixed block 12 can be detachably connected on respectively on holder 2 and the sliding seat 3 through modes such as bolt connections, and the size of nozzle pickup groove 13 is complementary with charging aperture 34 ends of the nozzle body 38 of corresponding nozzle to be measured 33 or the size of shower nozzle 35 ends.During concrete operations, only need that corresponding nozzle fixed block 12 is connected to holder 2 and get final product with sliding seat 3.
In order to prevent when carrying out nozzle 33 leak tested; Between the gas outlet 32 and the charging aperture 34 on the nozzle body 38 on the air inlet piece 5, occur leaking between shower nozzle 35 and the sealed nozzle cover 8, respectively has O-ring seal 14 on the said air inlet piece 5 of the nozzle leakage proving installation of TOP-TIP of the present invention and the sealed nozzle cover 8.Specifically, O-ring seal 14 is arranged on the contact position of gas outlet 32 and sealed nozzle cover 8 and shower nozzle 35 peripheries on the air inlet piece 5.
