Accompanying drawing explanation
Fig. 1 is a kind of portable pressure water sampler structural representation of the present utility model.
Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
See Fig. 1, a kind of portable pressure water sampler, comprises holding rod 1, bolt 2, depression bar 3, cavity 4, piston 5, air valve 6, tracheae 7, water tank 8, water valve 9, filter screen 10, water hole 11 and water pipe 12.Holding rod 1 is fixedly connected with by bolt 2 with depression bar 3, and the bottom of depression bar 3 connects piston 5 and connects, and piston 5 is built in cavity 4.Be provided with air valve 6 bottom cavity 4, and air valve 6 is communicated with water tank 8 by tracheae 7.The bottom of water tank 8 is provided with water valve 9, and the valve port of water valve 9 is provided with this filter screen 10.Water pipe 12 is communicated with water tank 8 by water hole 11, and water pipe 12 is for being communicated with sampling bottle.
Optimize, air valve 6 and water valve 9 are retaining valve, and when holding rod 1 drives this depression bar 3 to move downward, air valve 6 is opened, injecting gas in water tank 8, and water valve 9 cuts out, and adds large water tank internal gas pressure.When holding rod 1 drives depression bar 3 to move upward, air valve 6 is closed, and prevents gas and water sample from flowing backward in cavity 4.
