Embodiment Construction

[0019] (1) Composition: This instrument is mainly composed of a high-pressure to low-voltage stabilized sampler (1), an inlet valve (2), a nitrogen valve (3), a measuring cylinder (4), an outlet valve (5), and a vacuum pressure gauge (6) and other main components.

[0020] (2) principle: vacuumize the air in the metering cylinder (4) with the vacuum pump (7), and send the water sample with the nitrogen pressure of the nitrogen cylinder (8) to output the sample, so as to achieve the purpose of the whole process of airtight sampling.

[0021] (3) Technical solutions:

[0022] The high-low pressure airtight sampling feeder converts the high-pressure water sample at the sampling place into low-pressure stable-pressure storage and output, including high-pressure to low-pressure stable sampler (1), inlet valve (2), nitrogen valve (3), metering cylinder ( 4), outlet valve (5), vacuum pressure gauge (6), on-site oxygen-sealed airtight sampling and storage of water samples for up to 2...

Abstract

The invention relates to a high-low pressure airtight feeding sampler. The high-low pressure airtight feeding sampler is used for converting a high pressure water sample at a sampling site into a low steady voltage sample for storage and output. The high-low pressure airtight feeding sampler is applicable to laboratories and test cabinets of oil fields, environment monitoring, chemical industry, medicine, application or analytical chemistry relating to liquid.

Description

[0001] Technical field: Widely used in ① water quality analysis posts of oil recovery research institutes in various oil fields. ② The laboratory water quality analysis post of the Exploration and Development Research Institute. ③Water quality analysis post in the central laboratory of each oil production plant. ④The laboratory of each joint station of the oil production plant. ⑤The laboratory of the water injection station of the oil production plant. ⑥ Laboratories of oil production engineering majors in development departments of various petroleum colleges and universities. ⑦ Laboratories and laboratories of environmental monitoring, chemical engineering, medicine, applied or analytical chemistry and other liquid-related majors in various institutions. Background technique: [0002] In many oil field institutes and chemical enterprise colleges, in some water quality testing tests, it is necessary to isolate airtight sampling and give samples to ensure that the water samp...
