Embodiment 1
[0025] Example 1, see figure 2 , a high and low double sampling barrel structure provided by the present invention, comprising a first barrel 1 and a second barrel 2, the first barrel is located above the second barrel; the first barrel is provided with a first sampling port 101. The first water outlet 100 and the first overflow port 103, the first sampling port and the first overflow port are located at the top of the first bucket, and the first water outlet is located at the bottom of the first bucket end; the second barrel is provided with a second sampling port 201, a second drain port 200, a second overflow port 205, a sample supply port 202 and a sample return port 203, the second sampling port, the second overflow port The mouth and the sample return port are located at the top of the second bucket, the second water outlet is located at the bottom of the second bucket, and the sample supply port is located at the bottom of the second bucket; the first water outlet It ...
Embodiment 2
[0027] Example 2, see image 3 , the structure of embodiment 2 is substantially the same as that of embodiment 1, the difference is that a communicating pipe is provided between the first drain port and the second sampling port, the drain valve is installed on the communicating pipe, The communication pipe is also provided with a bypass pipe; one end of the bypass pipe is connected to the communication pipe, the connection position is located above the water valve, and the other end of the bypass pipe is connected to the communication pipe , the connection position is located below the bypass pipe, and an electric control valve 206 is installed on the bypass pipe; a detection device for detecting whether the liquid in the first barrel reaches a threshold value is arranged in the first barrel, Wherein, the detection device in this embodiment is a liquid level sensor, and the liquid level sensor is installed at the position of the first overflow port. When in use, the liquid le...
Embodiment 3
[0028] Example 3, see Figure 4 , the structure of embodiment 3 is substantially the same as that of embodiment 1, the difference is that the first overflow port is not communicated with the drain pipe, but communicated with the inside of the second bucket, generally in the second bucket A communication port is arranged at the top, and the communication port and the first overflow port are connected through pipelines. With this structure, when the water valve fails, the water sample in the first bucket cannot flow into the second bucket normally. After the water level rises to the position of the overflow port, the water sample in the first bucket flows into the second bucket through the overflow port, which can ensure sampling The continuity of the system prevents the normal operation of the water quality testing process from being affected when the water valve fails. Of course, a liquid level sensor can also be set at the position of the overflow port to detect the liquid l...
