Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.
Referring to Fig. 1 and Fig. 2, the drawing and pulling type drawer is processed in tool box 2, the drawer both sides are provided with guide rail, are convenient to pull.Main frame 1 is installed in the top in tool box 2, connects with box fastener, is convenient to dismounting.The height of main frame 1 is just in time meeting the human body operating position like this, need not couchant work, helps testing.When the needs tool using, can pull out the drawer in tool box, easily look for and getting, referring to Fig. 2.
Referring to being provided with unsteady flow metered valve assembly 4 in Fig. 3, the nitrogen flow regulating system, when operating according to electronic mode, nitrogen flows according to the solid arrow direction among Fig. 3.During use, open ball valve 5 earlier, just can adopt electronic nitrogen unsteady flow amount pattern.
When electronic mode breaks down, can adopt manual mode, i.e. dotted line route among Fig. 3.
Fig. 4-1 and Fig. 4-2, and said unsteady flow metered valve assembly comprises control module, displacement transducer 4-5, reducing motor 4-2 and valve part.Said valve part comprises valve body 4-1, valve rod 4-12, gland 4-10, seal 4-9 and valve pocket 4-8, and the front end of said valve rod 4-11 is the needle-valve head 4-7 of sealing valve port, can regulate nitrogen flow through needle-valve head 4-7 advance and retreat.
Has internal thread on the said valve pocket 4-8; Valve rod 4-12 has external thread; Valve pocket 4-8 and said valve rod 4-12 are through being threaded, and the rear end of said valve rod 4-12 is contained in the shift fork 4-3, and said shift fork 4-3 is fixed on the axle of said reducing motor 4-2; Rotation direction bar 4-11 is installed on the said valve rod 4-12, and the 4-6 of bar portion of said rotation direction bar 4-11 is resisted against on the said displacement transducer 4-5.Guide pole 4-4 in valve body 4-1 has the hole on the rod body part 4-6 of said rotation direction bar 4-11, and said guide pole 4-4 passes this hole, and is not shown.Rotation direction bar 4-11 can not rotate like this, can only follow valve rod 4-12 and move.
When needs adopt electronic mode that nitrogen flow is provided; Said control module receives the displacement signal of said displacement transducer 4-5 transmission; Control module according to displacement signal send control signal control said reducing motor 4-2 just/counter-rotating the number of turns; And then before controlling the valve rod 4-12 in the said valve part/the distance that moves the back, to regulate nitrogen flow.
For example, when reducing motor 4-2 clockwise rotated, shift fork 4-3 drove valve rod 4-12 rotation, and valve rod 4-12 moves forward through being threaded in rotation; Rotation direction bar 4-11 one end is fixed on the valve rod 4-12 through back-up ring 4-13, and the rod body part 4-6 of rotation direction bar 4-11 is inserted by guide pole 4-4, thereby rotation direction bar 4-11 can not rotate, and can only move.Thereby make displacement transducer 4-5 send various signals according to different displacement; The number of turns that the unlike signal control reducing motor 4-3 that sends through displacement transducer 4-4 rotates; And then control the distance that valve rod 4-12 moves forward, and then dwindle valve port, reduce nitrogen flow.4-2 is rotated counterclockwise when reducing motor, and valve rod 4-12 outwards moves and increases valve port, has increased nitrogen flow.
Referring to Fig. 5-1 and Fig. 5-3, all disposed skeleton oil sealing 9-1 in the oil gun adapter 9 up and down, like this when oil gun inserts; Utilize the lip seal of twice oil sealing, oil sealing and oil gun junction can tighten, and it seals good stability; Can do not uncovered easily, can not leaked gas.
Referring to Fig. 5-2, O type rubber seal is adopted in top sealing, and following oil sealing adopts skeleton oil sealing, and such array configuration also can reach the better seal effect.
Referring to Fig. 6, have the pole of 3 different-diameters on leak detection rod 10, promptly leak detection rod 10 is the pole that 3 sections ladder constitutes.1# among Fig. 6 excellent 10-1,2# excellent 10-2 and the 3# excellent 10-3 that hunts leak that hunts leak that hunts leak.As can be seen from Figure 6, hunt leak excellent 10-1 diameter of 1# is minimum, and 2# hunts leak excellent 10-2 diameter greater than the 1# excellent 10-1 that hunts leak, and 3# test bar 10-3 diameter is maximum.During use, can select the leak detection rod of suitable types according to the oil gun adapter of different-diameter.Such leak detection rod can be suitable for 3 kinds of oil gun adapters, need not to discern the relation of the test bar of oil gun adapter during use, has brought convenience to operation.Model on certain test bar can be not limited to 3 kinds.
Above disclosedly be merely a kind of preferred embodiment of the utility model, can not limit the interest field of the utility model certainly with this, the equivalent variations of therefore being done according to the utility model claim still belongs to the scope that the utility model is contained.
