Specific embodiment
The technical solution of the utility model is further described with reference to the accompanying drawings and embodiments:
In the description of the present invention, it should be noted that the orientation of the instructions such as term " on ", "lower", "front", "rear"
Or positional relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description the utility model and simplification is retouched
It states, rather than the device or element of indication or suggestion meaning must have a particular orientation, be constructed and operated in a specific orientation,
Therefore it should not be understood as limiting the present invention.In the present invention, handwheel 3 is rear, and thimble 4 is preceding.
Such as a kind of attached drawing 1 to attached pressure maintaining valve exhaust detection instrument shown in Fig. 3, including tool body 1, it is provided with tool sheet
Exhaust passage 2 on body 1, the front end of exhaust passage 2 from tool body 1 extend to rear end.Tool body 1 includes handwheel 3, connection
Thimble 4 on handwheel 3.Thimble 4 can press thimble at pressure retaining valve bleed outlet, and the gas in steel cylinder is released
Come, then gas is flowed out through exhaust passage 2.
Exhaust passage 2 includes the first exhaust by-path 21 being provided on thimble 4, the second exhaust branch being provided on handwheel 3
Road 22, first exhaust by-path 21 are connected with second exhaust by-path 22.Gas in steel cylinder is through first exhaust by-path 21 and second
By-path 22 is vented to flow out.
First exhaust by-path 21 has air inlet 211 and gas outlet 212, and air inlet 211 is provided with the side of thimble 4, out
Port 212 is provided with the rear end of thimble 4, and gas outlet 212 is connected with second exhaust by-path 22.In the present embodiment, air inlet
