Embodiment
Embodiment 1:
Technical scheme of the present invention is achieved in that it comprises the housing 17 that has chamber, housing is provided with liquid outlet and inlet respectively in two ends about in the of 17, in chamber, be provided with and open or to close inlet, the mechanism of liquid outlet, the upper end of housing 17 is provided with upper end cover 13, it is fixed on the housing 17 by attachment bolt 14, the central authorities of upper end cover 13 are provided with liquid outlet, the interface 15 of sensor etc. is set on the upper end cover 13, the opening and closing inlet, the mechanism of liquid outlet comprises up and down two sealing blocks 4 and 9, elastic component, marmem 5 and 10, cylindrical seal piece 2, two sealing blocks up and down can embed into, liquid outlet, elastic component by axial stretching between the sealing block connects, be provided with on the sealing block, liquid outlet channel, shape memory alloy spring is connected the end of elastic component, and this shape memory alloy spring embeds in the link slot of sealing block; Cylindrical seal body 2 is arranged on housing 17 bottoms and corresponding with lower seal piece 4 and housing 17 ends respectively, and the bottom of cylindrical seal body 2 extends to form inlet downwards; High pressure vessel interface 12 is set on the end cap 13, advancing on the sealing block, liquid outlet channel and inlet, liquid outlet is not on same axis, two sealing blocks lay respectively at the both sides of axial stretching spare, the sealing surface of sealing block is set to can embed into, the conical surface of liquid outlet, the external diameter of cylindrical seal body 2 matches with the internal diameter of housing 17 chambers, the internal diameter on its top matches with the external diameter of conical surface seal piece, the part that this cylindrical seal body 2 extends housing 17 is fixed on housing 17 bottoms by nut 1, the elastic component of axial stretching is common spring, the one end is supported and fixed in housing 17 chambers by spring suppport 7, in the outside of sampling thief heat insulation and heating equipment 18 is set.
As shown in Figure 1, before hydrothermal solution automatic sampler sampling of the present invention, be full of the normal temperature pure water in its inner cavity chamber, the shape memory alloy spring 5,10 of sealing block 4,9 is in contraction state, common spring 6,8 is in contraction state, the inlet of sampling thief and liquid outlet also are in the state of opening, and the liquid in-out passage of sealing block 4,9 also is in open mode like this.When sampling thief is put into the hydrothermal solution that needs sampling, because hydrothermal solution is in upwards spray regime, hydrothermal solution will enter sampling thief from the inlet of its underpart, then through sealing block 4,9 liquid in-out passage, enter into the inner chamber of sampling thief, at this moment shape memory alloy spring 5,10 are heated, to recover its memorized shape, it is elongation state elasticity enhancing simultaneously, thereby promote sealing block 4,9 move to the two ends of sampling thief, sealing block 4,9 the conical surface just in time snaps into inlet and the liquid outlet place on the sampling thief, and Qu Yang hydrothermal solution just is sealed in the inner chamber of sampling thief (as shown in Figure 2) like this.In the time need discharging the hydrothermal solution in the sampling thief inner chamber, will seal release screw 14 and turn on, hydrothermal solution can be discharged to the place that needs from the inner chamber of sampling thief.After the liquid of sampling is discharged from the inner chamber of sampling thief, temperature in its inner chamber is also just along with the discharge of hydrothermal solution has reduced, shape memory alloy spring 5,10 is also along with the reduction deliquescing of temperature, simultaneously common spring 6,8 shrinks, like this, sampling thief is got back to state shown in Figure 1 again, and sampling thief can be sampled again, has realized the repeated use of sampling thief.Wherein sealing ring 3,11 seals. Common spring 6,9 and spring suppport 7 play axial stretching and support, and support is fixed on the inner walls.When sampling thief is sampled, because the outside of sampling thief is provided with heat insulation and heating equipment 18, start heating arrangement, to keep the temperature of sampling thief inner chamber hydrothermal solution.
Embodiment 2:
The difference of present embodiment and embodiment 1 is that the hold-down nut 1 of the cylindrical seal body of sampling thief bottom is turned on.
When the needs gastight sampling, as shown in Figure 3, the seal nut 1 of sampling thief bottom is turned on, at this moment, cylindrical seal body 2 in the sampling thief inner chamber just slides in the chamber within it, sampling thief is proposed from the liquid of sampling at once, demonstration according to the pressure transducer that connects on the pressure sensor interface 15, configure the value of pressure chamber, then high pressure vessel interface 12 is received and configured force value, have on the pressure chamber of overflow mechanism, at this moment, give 2 one external force of cylindrical seal body, liquid in the sampling thief chamber will flow in the pressure chamber, and cylindrical seal body 2 also slides along the inside surface of housing 17, and the liquid volume in the sampling thief reduces, simultaneously pressure chamber is can overflow constant to keep-up pressure, can keep the pressure in the sampling thief constant like this, most of liquid is discharged in the pressure chamber in sampling thief, thereby has realized the gastight sampling of sample liquid.
Hydrothermal solution automatic sampler of the present invention compared with prior art has the following advantages:
1, hydrothermal solution automatic sampler of the present invention is provided with inlet and liquid outlet, this sampling thief is when gathering hydrothermal solution, hydrothermal solution can enter sampling thief inside by the sampling thief lower openings, flow out by the sampling thief upper opening, because hot-fluid effect, hydrothermal solution is gone out the inner original liquid of sampling thief, thereby guarantees that sampling thief inside does not retain primary liquid.
2, sealing block of the present invention adopts marmem as spring, after hydrothermal solution enters sampling thief, spring is heated, spring will recover institute's memorized shape, rely on the memory alloy spring restoring force, driving is positioned at the sealing block of upper and lower opening inside, and hydrothermal solution is sealed in the inner chamber of sampling thief, has realized the automatic sampling function of sampling thief.
3, the present invention is provided with end cap in the upper end of housing, after hydrothermal solution is discharged from the inner chamber of sampling thief, can open end cap, cleans inner chamber, changes spring, and sampling thief can reuse, thereby has solved the repeated use problem of sampling thief.
4, the present invention is arranged on the cylindrical seal body of bottom a seal hold-down nut, when not needing gastight sampling, this cylindrical seal body hold-down nut plays the effect of holding cylindrical seal, when the needs gastight sampling, the seal hold-down nut is taken off, the cylindrical seal body can slide in the inner cavity chamber of shell, also be provided with the high pressure vessel interface on the shell of the present invention, interface can be directly connected to other high pressure vessel, can slide relying on external force to promote the cylindrical seal body like this, the direct pressurize of hydrothermal solution sample is transported in the high pressure vessel that is connected with the high pressure vessel interface.Solved the gastight sampling problem after sampling thief is gathered the hydrothermal solution sample.
5, hydrothermal solution automatic sampler of the present invention can be provided with heat insulation and heating equipment as required outside, heat insulation and heating equipment can be set in sample time when long, can keep the temperature-resistant of liquid in the sampling thief, has realized the insulation sampled functions of sampling thief; If when take out hydrothermal solution the sampling back, heat insulation and heating equipment can be set at once.
The parts of the above sampling thief all are to adopt material high temperature resistant, the acid resistance corrosion to form, and hydrothermal solution automatic sampler of the present invention can be widely used in the sampling field of high temperature high pressure liquid under the hyperbaric environment or fluid.
