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, need sometimes the water of certain depth is taken out, deliver to that the laboratory chemically examines
The depthkeeping sampler.
Background technology
Along with rapid economic development, more and more higher to the management expectancy of water resource.Because a variety of causes, need be to water body, comprise that underground water and surface water monitor.For different requirements, need carry out chromatographic analysis to the different layer of water body.Because water is fluid, former sampling method such as sampling equipments such as sampling jar, sample bucket make the water blending of different layers easily.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of not blending stratified sampling of realizing
Vacuum type depthkeeping samplerRealize that the technical scheme that purpose of the present invention is taked is: this vacuum type depthkeeping sampler is provided with a cylinder, the upper end of cylinder is provided with Mi Feng Cover, Shang Mi Feng Cover 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.Be respectively equipped with screw thread on said Shang Mi Feng Cover and the cylinder, Shang Mi Feng Cover and cylinder are for being threaded.The lower end of cylinder is provided with Xia Mi Feng Cover, has axis hole and inlet opening on Xia Mi Feng Cover, cooperates with axis hole to be provided with bearing pin, and the upper end of bearing pin is provided with water intaking valve, and the lower end of bearing pin is provided with the counterweight stop nut, and bearing pin can drive the upper and lower motion of water intaking valve.Be respectively equipped with down screw thread on said Xia Mi Feng Cover and the cylinder, Xia Mi Feng Cover and cylinder are for being threaded.Be provided with elastic capsule in the cylinder, the mouth down spiral-lock of elastic capsule is on water intaking valve.The present invention is that the vacuum of utilizing elastic capsule to form obtains desired water sample with target water sample suction elastic capsule.Elastic capsule can be compressed into flat under the external pressure effect, gets rid of all gas in the capsule.Remove external force, the elastic capsule reinstatement of can upspringing produces certain vacuum tightness (negative pressure) when recovering, under the effect of negative pressure water is sucked elastic capsule by the inlet opening.The top is connected with mark and establishes the pipe of length, and the pipe other end has air inlet and exhaust valve.The cylinder lower end is provided with water intaking valve, and the inlet opening is connected with capsule.
The present invention sucks principle according to vacuum, and is simple in structure, in use not fragile, take a sample accurately and reliably, and not blending of liquid, result of use is good, utilizes it in the degree of depth that requires water sample to be taken out in the large volume water body of inspection well.
