Description
Technical field
The utility model belongs to hydrographic water resource surveying instrument technical field, relates in particular to a kind ofly in the observation process of water resource, need the water of certain depth be taken out sometimes, delivers to
depthkeeping ST of chemically examining in the laboratory.
Background technology
Along with rapid economic development, increasingly high 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.From different requirement, 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
To the problems referred to above, the purpose of the utility model provides a kind of not blending stratified sampling of realizing
Vacuum type depthkeeping STThe purpose of the present utility model technical solutions adopted are: the vacuum has a fixed depth sampler cylindrical body, on the upper end of the cylindrical body closures, sealing cap on a pipe joints, pipe joints located on There are intake and exhaust pipes, intake and exhaust pipe has a scale, the intake and exhaust pipe ends with charge and discharge valve.Said sealing cap and the cylindrical body are respectively provided on the threaded closure cap on the cylindrical body is threaded connections.The lower end of the cylindrical body has a lower closures, closures on the opening under the shaft hole and water holes, and the shaft hole with a pin, the pin with the upper end of the inlet valve, the lower end of a pin with weight limit nuts, inlet valve pin can drive up and down movement.Said lower closure cap, respectively, the cylindrical body provided with a lower thread, the closure cap and the cylindrical body is threaded connections.Be provided with elastic capsule in the cylinder, the mouth down spiral-lock of elastic capsule is on water intaking valve.The utility model 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 action of negative pressure, water is sucked elastic capsule by the inlet opening.The top is connected with mark and establishes length of tubing, 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 utility model 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 big water by volume body of inspection well, in the degree of depth that requires water sample to be taken out.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of lower sealing cover in the utility model.
Figure 1, the cylindrical body 2, the upper sealing cover, 3, fittings, 4, into the exhaust pipe 5, the scale, 6, charge and discharge valve 7, the thread 8, the sealing cap 9, the shaft hole 10, inlets, 11, pin 12, the inlet valve, 13, counterweight limit nut 14, the next thread, 15, elastic capsules.
Specific embodiments
Referring to the drawings, the vacuum has a fixed depth sampler cylindrical body 1, the upper end of the cylindrical body has an upper Grommet 2, the sealing cover 2 is provided with fittings 3, 3 is provided with inlet pipe joints, exhaust pipe 4, the intake and exhaust pipe 4 with scale 5, intake and exhaust pipe 4 ends with charge and discharge valve 6.Said upper sealing cap 2 and the cylindrical body 1, respectively, with the thread 7, the sealing cap 2 and the cylindrical body 1 is a screw connection.The lower end of the cylindrical body 1 is provided with a lower closure cap 8, the sealing cover 8 is formed with a shaft hole 9 and the inlet hole 10, and the shaft hole 9 with a pin 11, the pin 11 of the upper end of the inlet valve 12, the pin 11 has a weight limit of the lower end of the nut 13, the pin 11 can drive the inlet valve 12, the next movement.Said lower sealing cover 8 and the cylindrical body 1 are respectively provided with a lower thread 14, the sealing cover 8 and the cylindrical body 1 is a screw connection.Be provided with elastic capsule 15 in the cylinder 1, the mouth down spiral-lock of elastic capsule 15 is on water intaking valve 12.Elastic capsule 15 is compressed air compression in cylindrical shell 1, remove the reinstatement of upspringing behind the pressure gas, forms certain vacuum tightness.
Concrete use: according to accompanying drawing with device assembles good after; At first use charger through fill, air release 6, air inlet and exhaust piper 4, and pipe adapter 3 in ST cylinder 1, inflate; Under certain pressure; Elastic capsule 15 is squeezed, and elastic capsule 15 cavity volume diminish, and the air in the elastic capsule 15 is discharged through inlet opening 10.Keep this state, utilize the air inlet and exhaust piper 4 that indicates length scale 5 the ST staving to be put into the degree of depth that requires in the water body.Leave standstill a period of time.Open into then fill, air release 6, elastic capsule 15 resiles under the elastic force effect of self, forms certain vacuum tightness, water through inlet opening 10, back down in the water intaking valve 12 inspiration elastic capsules 15.Water enters in the elastic capsule, fills elastic capsule, and water intaking valve 12 falls, and water is stayed in the elastic capsule 15.Counterweight and stop nut 13 restriction water intaking valves 12 are inhaled in the elastic capsule under vacuum action.Propose ST to ground, with pushing away on the water intaking valve 12, water flows out under action of gravity, and sampling process finishes.
