Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-4 is please referred to, the present invention provides a kind of technical solution: a kind of Portable valve leakage detection apparatus, including upper and lower two
The symmetrically arranged holding frame 1 in side is connected between the side wall of the holding frame 1 of two sides, the mutually view of the holding frame 1 of two sides by strut 2
Holding tank 3 is offered on side wall, the middle part of support 1 longitudinally offers through slot, and slide bar 4, the slide bar 4 of upside are plugged in through slot
For hollow slide bar, the slide bar 4 of upper and lower two sides is mutually bolted with pressing plate 5 depending on end, is bonded on the outer wall of pressing plate 5 by bonding agent
Gasket 6 is socketed with support rod 7 on the outer wall of slide bar 4, and support rod 7 is fixedly connected by screw with the outer wall of slide bar 4, clamping
Locating rack 8 is fixedly connected with by screw on the lateral wall of frame 1, check valve 9, slide bar 4 are installed on the pipeline of the slide bar 4 of upside
Outer wall on air pressure detection table 10 is installed, air pressure detection table 10 is connected to the inner cavity of slide bar 4, the top company of the slide bar 4 of upside
It is connected to suction nozzle 11.
Wherein, the two sides of holding tank 3 pass through pin shaft and are connected with idler wheel, and gasket 6 is rubber gasket, and support rod 7 wraps
Casing and the lateral pivoted arm on the right side of casing are included, is connected between casing and lateral pivoted arm by pin shaft, the upper table of lateral pivoted arm
