The vacuum fixed-depth sampler is accurate and reliable in sampling, liquids cannot be mixed, and a water sample can be taken out at a required depth.
Description
Technical field
The invention belongs to hydrographic water resource surveying instrument technical field, relate in particular to a kind ofly in the observation process of water resource, sometimes need the water of certain depth to take out, deliver to that laboratory chemically examines
depth sampler.
Background technology
Along with developing rapidly of economy, more and more higher to the management expectancy of water resource.Due to a variety of causes, need to be to water body, comprise that underground water and surface water monitor.For different requirements, need to carry out chromatographic analysis to the different layer of water body.Because water is fluid, former sampling method, as the sampling equipment such as sampling jar, sample bucket, easily makes the water blending of different layers.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of not blending stratified sampling of realizing
vacuum type depth sampler.Realizing the technical scheme that object of the present invention takes is: this vacuum type depth sampler is provided with a cylinder, the upper end of cylinder is provided with top cover labyrinth, top cover labyrinth is provided with pipe adapter, pipe adapter is provided with air inlet and exhaust piper, air inlet and exhaust piper is provided with scale, the end of air inlet and exhaust piper be provided with fill, air release.On said top cover labyrinth and cylinder, be respectively equipped with screw thread, top cover labyrinth with cylinder for being threaded.The lower end of cylinder is provided with lower sealing cover, has axis hole and inlet opening in lower sealing cover, is provided with bearing pin with shaft hole matching, and the upper end of bearing pin is provided with water intaking valve, and the lower end of bearing pin is provided with counterweight stop nut, and bearing pin can drive the upper and lower motion of water intaking valve.On said lower sealing cover and cylinder, be respectively equipped with lower screw thread, lower sealing cover with cylinder for being threaded.In cylinder, be provided with elastic capsule, the mouth down spiral-lock of elastic capsule is on water intaking valve.The present invention utilizes the vacuum that elastic capsule forms that target water sample suction elastic capsule is obtained to desired water sample.Elastic capsule can be compressed under pressure-acting flat outside, gets rid of all gas in capsule.Remove external force, the elastic capsule reinstatement of can upspringing produces certain vacuum tightness (negative pressure) in the time recovering, and under the effect of negative pressure, water is sucked to elastic capsule by inlet opening.Top is connected with mark and establishes the pipe of length, and the pipe other end has air inlet and exhaust valve.Cylinder lower end is provided with water intaking valve, and inlet opening is connected with capsule.
The present invention sucks principle according to vacuum, simple in structure, in use not fragile, sample accurately and reliably, and not blending of liquid, result of use is good, utilizes it in the large volume water body of inspection well, in the degree of depth requiring, water sample to be taken out.
