Sewage in dirty pipe carries out analysis detection.Water loop module is housed, to will be in pressure piping 111 on the inlet pipeline 1
Sewage is led in the bypass microcirculation of pressure piping, to guarantee the sewage arranged in taken water sample and pressure piping 111
Synchronous homogeneity.The water loop module is made of the inlet valve 11 and circulating pump 12 being arranged on the inlet pipeline 1, in order to just
In maintenance, hand-operated valve 13 is additionally provided in the water loop module, the hand-operated valve 13 is mounted on the inlet valve 11 and circulation
The two sides of pump 12.In the present embodiment, the water loop module is arranged in parallel on inlet pipeline 1, to prevent water cyclic module all the way
When block fails, another way can be worked normally, and ensure equipment reliability of operation.Water flow sensing is additionally provided on the inlet pipeline 1
Device 14, to perceive the streamflow regime in pipeline.
One end of the inlet pipeline 1 is used to be connected with pressure piping 111, and the other end is connected to described by sampling valve 6
Circulation barrel 2 is connected with diversion pipe 71 on the sampling valve 6, and the diversion pipe 71 extends to the bottom of the circulation barrel 2, the row
Sewage in water lines 3 from the bottom injection circulation barrel 2 inside the circulation barrel 2, is followed via the diversion pipe 71 described
Circulation water sample to be collected is formed in ring bucket 2.The discharge pipe line 3, the row are connected at the upper port of the circulation barrel 2
Relief valve 31, sensor 32, outlet valve 33 and hand-operated valve 13, the circulation water sample in the circulation barrel 2 are successively arranged in water lines 3
Pressure piping 111 can be cycled back to by discharge pipe line 3.The relief valve 31 is three-way electric valve, and one end is for being connected to atmosphere.
The sensor 32 can configure as needed, be detected with the various data to water quality, by control system according to the data
Control the opening and closing of respective valves.The inlet pipeline 1, circulation barrel 2 and discharge pipe line 3 just constitute circulation line, to pressure piping
Sewage in 111, that is, blowoff line carries out real-time circulation.
Air pump 5 is also connected on the circulation barrel 2, the air pump 5 is connected to the circulation barrel by emptying pneumatic operated valve 51
2, for emptying the circulation water sample in the circulation barrel 2.When emptying circulation barrel, need to first pass through sampling valve 6 for inlet pipeline 1
Access between circulation barrel 2 is connected to, and opens inlet valve 11, is pressurizeed using the air pump 5, by the circulation water sample in circulation barrel 2
It is pushed back by diversion pipe 71 to the inlet pipeline 1, and is further pressed back into pressure piping 111, to empty the circulation barrel
2。
The sampling valve 6 is three-way electric valve, is further connected with sample lines 7 thereon, the end of the sample lines 7 is connected with
Sample mixing bucket 10, the sample mixing bucket 10 is for storing the water taken from the circulation barrel 2 by certain sample mode as needed
Sample.The sample lines 7, which are equipped with, to keep sample valve 8 and sampling pump 9, the sampling pump 9 be can positive and negative rotation peristaltic pump.It is described to keep sample
