The outer guard shield 29 that is equipped with of this device.
The live axle 2 of reciprocating motor 1 drives plunger 4 by joiner 3 and pumps.When plunger 4 was descending, poppet valve 15 was opened, and the liquid sample that flows in the pipeline center hole 9 of the radial hole 17 by plunger bushing 20 bottoms, poppet valve 16 plungers 4 and radial hole 8 thereof successively is full of annular space 5 between plunger 4 and the plunger bushing 20.
When plunger 4 was up, poppet valve 15 cut out the inlet opening of lifting valve base 16, and the liquid sample of 5 li of annular spaces is pumped into sample tube 25 by joint 24, stop valve 28, differential pressure type automatic switch valve 27 and flexible pipe 26 successively.
Because the pressure in the pipeline is higher than the pressure in the sample tube all the time, liquid in the pipeline does not flow into the sample tube when plunger is descending in order to make, and the theory that its sampling amount is no more than plunger when plunger is up promotes volume, and specialized designs the differential pressure type automatic switch valve, as shown in Figure 2, the radial hole 37 of valve body 31 makes the interior pressure of pipeline act on the left end of piston 35 all the time by flexible pipe 22 and stop valve 21 and 19 interior connections of pipeline.Because of the bearing area at piston 35 two ends equates, under the spring force effect, piston 35 can valve body fluid radial hole 34 when sampling plunger 4 is descending, make the liquid sample in the pipeline not enter sample tube 25 by this valve, and when sampling plunger 4 is up, because the pressure of this valve inlet liquid is enhanced, the active force that piston 35 is produced to left movement, when this active force during greater than spring force, piston 35 moves to left, and open fluid radial hole 34, the liquid sample is entered in the sample tube 25 by the feed liquor radial hole 33 on the valve body, fluid radial hole 34 and flexible pipe 26.
For making the depth selection in pipeline adjustable, designed the structure that plunger bushing 20 can upper and lower adjustings, promptly connecting cylinder 7 is tightened fixingly by screw thread and stuffing box gland 10, reaches the purpose of plunger bushing 20 liftings adjusting by rotation and lifting nut 6.
By rotation and lifting nut 6, plunger bushing 20 is upwards risen, compress, seal until the sealing valve face 18 of plunger bushing 20 bottoms and the valve port 19 of stuffing box gland 10 bottoms.
Can be by the reciprocating frequency of regulating motor the frequency of its sampling of regulated at will.
