Embodiment Construction

[0058] Such as figure 1 As shown, the sampler of the present invention includes a steady flow buffer pipe 9, a pump pipe connection mechanism, a diverter pressure regulating valve, a pressure gauge 7, a sampling hose 1, and a concentric flow regulator.

[0059] The steady flow buffer tube 9 is a cylindrical tube body made of 304 stainless steel with openings at both ends. Its upper port is provided with a convex edge and a pump tube connection mechanism to realize the fixation with the polluted water sample output pump tube. connect. A streamlined water outlet 8 is opened on the pipe wall of the steady flow buffer pipe 9 , and the sampling hose 1 is fixedly connected to the outer port of the streamlined water outlet 8 . The lower port of the steady-flow buffer pipe 9 is provided with a diverter pressure-regulating valve for adjusting the opening of the port of the steady-flow buffer pipe 9 to adjust the water flow pressure of the polluted water sample in the pipe body.

Abstract

The invention relates to a tube orifice diameter variable spliced sampling instrument which structurally comprises a steady flow buffer tube for receiving a pumped polluted water sample and performing steady flow conveying on the polluted water sample, a pump tube connection mechanism connected with a polluted water sample output pump tube, a diversion pressure regulating valve for regulating water flow pressure of the polluted water sample, a pressure gauge for detecting the water flow pressure, a sampling hose leading the polluted water sample under a laminar condition out of the steady flow buffer tube via a streamline water outlet for water sampling, and a concentric flow regulator for regulating a flow rate of the collected water sample. The instrument changes the composition, the structure and the operating principle of the original organic polluted water sampling device, has the characteristics of small size, light weight, wide application scope, convenience in carrying and mounting, simplicity in operation, safety in use, prevention of a pollution link in a collection process of the sample and the like, improves the fidelity of the collected sample, lowers the collecting cost of the sample, and ensures the safety of personnel and equipment, and the universality of the sampling instrument is improved.

Description

technical field [0001] The invention relates to a collection device for water samples containing volatile and semi-volatile substances, in particular to a plug-in sampler with a variable diameter nozzle. Background technique [0002] Due to the particularity of volatile and semi-volatile substances contained in water samples polluted by organic matter, the collection of samples is different from other water samples. [0003] At present, the commonly used method of collecting water samples contaminated by organic matter is to fasten the fire hose with a hose clamp at the mouth of the pump pipe where the contaminated water sample is drawn, and then collect the sample through a four-way diversion method. 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 , disc...
