One end of described micro-water test pipe joint is fixedly connected with crossover sub nut, the other end is connected with micro-water testing instrument pipeline matching thread, micro-water test pipe joint is cylindrical structure, the outer wall of micro-water test pipe joint is provided with outside thread, micro-water test pipe joint is coaxially arranged with crossover sub nut, and micro-water test pipe joint is inner offers the through hole with crossover sub nut with coaxality.
Described crossover sub nut is hexagon nut.
The joint of described crossover sub nut and loading line jointing is provided with seal ring.
The end that described micro-water test pipe joint and micro-water testing instrument pipeline are connected is segment shape, and the spherical crown outer surface of this segment is smooth surface.
By above-mentioned design proposal, the utility model can bring following beneficial effect: utilize all loading line afterbodys in prior art to be all connected mutually with secondary decompression valve, shape is unified, a kind of general crossover sub for connecting micro-water testing instrument of the present utility model, loading line jointing matches with loading line and is threaded, the joint of crossover sub nut and loading line jointing is provided with seal ring simultaneously, and seal ring and crossover sub nut screw connection are pressed tighter and tighter, not easily leak gas; Because micro-water testing instrument pipeline adopts plastic material usually, the end that micro-water test pipe joint of the present utility model and micro-water testing instrument pipeline are connected is segment shape, and the spherical crown outer surface of this segment is smooth surface, micro-water test pipe joint and micro-water testing instrument pipeline can reduce friction when being connected, extend the working life of micro-water testing instrument pipeline, simultaneously better tightness.A kind of general crossover sub for connecting micro-water testing instrument of the present utility model, make simple, good airproof performance, anti-gas-leak, feasibility are strong, and fabrication cycle is short, can be directly applied for whole operation field after completing.
