Embodiment Construction

[0048] Such as figure 1 As shown, the sampler of the present invention includes a steady flow buffer tube, a pump tube connection mechanism, a diverter pressure regulating valve, a pressure gauge, an arc-shaped sampling core tube, a mass stabilizer, a flow regulator, and a sampling hose.

[0049] The steady-flow buffer tube 9 is a cylindrical tube body made of 304 stainless steel with openings at both ends. The upper port of the tube body is provided with a convex edge and a pump tube connection mechanism to realize the output of the pump tube with the polluted water sample. The lower end of the steady flow buffer pipe 9 is provided with a downwardly extending bottleneck, and a shunt pressure regulating valve is arranged in the bottleneck to adjust the water flow pressure of the polluted water sample in the pipe body by adjusting the opening. A pressure gauge 7 is installed on the pipe wall of the steady-flow buffer pipe 9 for detecting the water flow pressure of the polluted ...

Abstract

The invention relates to a negative pressure sampler for collecting a water sample containing organic pollutants. The negative pressure sampler comprises a flow stabilizing buffer tube, a pump tube connection mechanism, a flow dividing and pressure regulating valve, an arc-shaped sampling core pipe, a quality stabilizer, a flow regulator, a sampling hose and the like. The negative pressure sampler provided by the invention has the advantages of light weight, convenience in carrying and mounting, simple operation and use safety. Particularly, the collected water sample has a slow change in flow direction and a stable flow line due to the use of the quality stabilizer, thereby obviating generation of air holes, realizing good redissolution effect, improving fidelity of the collected sample, lowering the sample collection cost, ensuring the safety of personnel and equipment and improving the universality of the sampler.

Description

technical field [0001] The invention relates to a collection device for water samples containing volatile and semi-volatile substances, in particular to a negative pressure sampler for water samples polluted by organic matter. Background technique [0002] Water samples polluted by organic matter, because they contain volatile and semi-volatile substances, are different from ordinary water samples when collecting samples. 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-...
