The utility model beneficial effect:
Compared with prior art, the utility model fits together taper mineral electrodes, sealed insulation tapered sleeve, insulation cone pad, lead-in wire and pedestal, form taper self-energized seal technology, during use along with the increase of autoclave internal pressure, sealed insulating material distortion is larger, the better effects if of sealing, the electro-chemical test work that can be applicable to the hydrothermal system under normal temperature ~ 500 ℃ and normal pressure ~ 100MPa condition, can effectively solve prior art and can not under the above condition of supercritical water (374 ℃ and 22 MPa), carry out the problem of electro-chemical test; Insulation cone pad and sealed insulation tapered sleeve adopt mica or pyrophyllite or boron nitride to make, and High Temperature High Pressure lower seal insulating property are better; Lead-in wire exposed part has insulating ceramics pipe outward, plays the effect of insulation protection; Pedestal adopts titanium material processing and fabricating, and high temperature resistance high pressure corrosive nature is good.
accompanying drawing explanation:
Fig. 1 is the structure cut-open view of the utility model mineral working electrode.
embodiment:
Embodiment 1: as Fig. 1, mineral working electrode for water under high pressure hot system electro-chemical test, lead-in wire 6 is connected with mineral electrodes 1 through the through hole on insulation cone pad 3, insulation cone pad 3 is arranged on the bottom of sealed insulation tapered sleeve 2, mineral electrodes 1 is arranged on the top of sealed insulation tapered sleeve 2, and sealed insulation tapered sleeve 2 packs in the taper hole of pedestal 4.
Mineral electrodes 1 adopts chalcopyrite to make.
Insulation cone pad 3 and sealed insulation tapered sleeve 2 adopt micas or pyrophyllite or boron nitride to make, and High Temperature High Pressure lower seal insulating property are better, and the aperture that insulation cone pad 3 centers are processed with 0.5mm is convenient to go between and 6 is passed.
Lead-in wire 6 adopts the spun gold of 0.5mm, conducts electricity very well.
There is insulating ceramics pipe 5 the 6 exposed parts outsides that go between, play insulation protection effect.
Pedestal 4 adopts titanium material processing and fabricating, and high temperature resistance high pressure corrosive nature is good, and pedestal 4 can be still plug or the still wall of autoclave.
During use, sealed insulation tapered sleeve 2 is packed in the taper hole of pedestal 4, again lead-in wire 6 is padded to the through hole at 3 centers through insulation cone, and expose lead-in wire 6 joints, then integral body packs in sealed insulation tapered sleeve 2, then mineral electrodes 1 is packed in sealed insulation tapered sleeve 2, and is pressed on lead-in wire 6 joints, at lead-in wire 6 exposed parts, insulating ceramics pipe 5 is housed outward, by unit clamp, mineral electrodes 1 and sealed insulation tapered sleeve 2 compressions is reached to initial sealing.After mineral working electrode has been assembled, measure mineral electrodes 1, go between 6 and pedestal 4 between resistance, to prevent from opening circuit or the generation of short circuit.
In use, along with the increase of high-temperature high-pressure reaction kettle internal pressure, the power that acts on mineral electrodes 1, insulation cone pad 3 and sealed insulation tapered sleeve 2 is larger, and due to self-tightening sealing effect, the effect of sealing can be better.
