Embodiment 1

[0042] Such as figure 1 Shown, the water sample collection system of the present invention comprises the wellhead connection sampling device 1 that is arranged on the wellhead of the pressurized well, the output port of the wellhead connection sampling device 1 is connected to the input port of the self-priming pump 2 through a flexible pipe, and the self-priming pump 2 The output port is connected to the tee 5 through a pipeline, and the upper port of the tee 5 is connected to two series-connected expansion tube filters 7 through a pipeline, and the upper port of the upper expansion tube filter 7 is connected to the mass stabilizer 3 through a pipeline. The input port is connected to the bypass port of the tee 5 with the diversion control valve 4, and the output port at the upper end of the mass stabilizer 3 is connected to the split combined sampling bottle 6 through a pipeline.

[0043] The expansion tube filter 7 is an optional part in the water sample collection system, a...

Embodiment 2

[0053] A water sample collection method for sampling from a pressurized well, comprising the following steps:

[0054] 1. The construction of the water sample collection system: first use a glass bottle to take a small amount of water from the pressurized well to be sampled and observe the water quality of the water. , the diversion control valve 4 and the mass stabilizer 3 are assembled and connected to form the main body of the water sample collection system; The device 3 and two expansion tube filters 7 are assembled and connected to form the main body of the water sample collection system. The mass stabilizer 3 should be adjusted to be vertically arranged above the output port of the self-priming pump 2, and the expansion tube filter 7 is connected below the mass stabilizer 3 and is on a vertical line with the mass stabilizer 3.

[0055] 2. Take off the pressure handle and the water lifting mechanism on the wellhead 8 of the pressure water well to be sampled, install and ...

Abstract

The invention relates to a water sample collection system and a water sample collection method for sampling from a pressurized well. The water sample collection system is provided with a wellhead connection sampling device on the wellhead of the pressurized well, and the output port of the wellhead connection sampling device is passed The hose is connected to the input port of the self-priming pump, the outlet port of the self-priming pump is connected to a tee, and the upper port of the tee is connected to the input port of the mass stabilizer through a pipeline. The bypass port is connected with the diversion control valve, and the output port at the upper end of the mass stabilizer is connected with a split combined sampling bottle through a pipeline. The invention can realize rapid installation and positioning of the well pipe of the pressurized well, and improves the convenience and convenience of the sampling operation; the water sample and the environmental sensitive substances contained in it pass through the water sample collection system in a state of relative dynamic balance, and are disturbed Small, less precipitation of volatile substances, improving the fidelity of the sample.

Description

technical field [0001] The invention relates to a water sample sampling device and a collection method for water quality research, in particular to a water sample collection system and a water sample collection method for sampling from a pressurized well. Background technique [0002] The commonly used method of collecting water samples contaminated by organic matter is to fasten the fire hose with a hose clamp at the pump nozzle where the contaminated water sample is drawn, and then collect samples by means of four-way diversion. The sampling components used mainly include sample collection four-way, four-way diverter, lined fire hose, hose clamps, large and small pipe joints, straight pipes, quick-connect snap rings, pressure gauges, socket-type connection towers, and pressure regulating valves , discharge valve, transparent pressure-resistant plastic hose, flattened flow regulator and stainless steel pipe, etc. When sampling, the assembly and on-site installation of the ...
