Utility model content
In order to solve the problem, the utility model devises a kind of vacuum type electrode level measuring device, at utmost decrease that water temperature in cylindrical shell is affected by the external environment and the temperature that produces reduces, to make in cylindrical shell water temperature always close to water temperature in drum, measure accurate stable, solve the problem that level measuring deviation that existing electric contact point fluviograph causes far below water level in drum because of water temperature in measuring cylinder is large.
The technical solution of the utility model is:
A kind of vacuum type electrode level measuring device, comprise airtight inner barrel and outer cylinder body, separation layer is formed between described inner barrel and outer cylinder body, some inside and outside cylindrical shell spacing blocks are provided with in described separation layer, the end of described separation layer is connected with vacuum pump by vacuum adapter, by vacuum pump, separation layer is vacuumized, thus achieve and every thermal property, the effect of a heat-insulation and heat-preservation is played to the high-temperature water in inner core by vacuum layer, to make in inner core water temperature close to water temperature in drum, at utmost decrease that water temperature in cylindrical shell is affected by the external environment and the temperature that produces reduces, to make in cylindrical shell water temperature always close to water temperature in drum, measure accurate stable.
Further, the upper end of described inner barrel is provided with upper sealing ring, and lower end is provided with lower sealing ring, and described vacuum adapter is arranged on described upper sealing ring.
Further, the upper end of described outer cylinder body is provided with upper cover, and lower end is provided with low head, and bottom is provided with pollution discharge joint.

Embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment 1
As shown in Figure 1, a kind of vacuum type electrode level measuring device comprises endothecium structure part and layer structure part, by upper cover 1, outer cylinder body 2, low head 3, pollution discharge joint 4, water side joint pipe 5, vapour side joint pipe 6 constitutes vacuum type electrode level measuring device layer structure part, by special upper sealing ring 7, special vacuumizing joint 8, inner barrel 9, inside and outside cylindrical shell spacing block 10, special lower sealing ring 11, constitute vacuum type electrode level measuring device endothecium structure part, this part needs by designing requirement assembling and welding, the welding manner of various piece adopts argon arc welding.After endothecium structure completes by designing requirement and outer cylinder body 12 assembly welding to together with, now separation layer is formed, following vacuum pump is vacuumized to separation layer by special vacuumizing joint 8, vacuumize rear argon arc welding the soldering and sealing of special vacuumizing joint 8, leaked to prevent in use special vacuumizing joint 8.After having vacuumized just can by designing requirement upper cover 1, outer cylinder body 2, low head 3, pollution discharge joint 4, water side joint pipe 5, vapour side joint pipe 6 assembly welding to together, welding manner adopts argon arc welding equally.After vacuum type electrode level measuring device internal and external parts all completes, need to carry out the hydraulic testing, test pressure 32MPa pressurize 30 minutes, leak source and pressure release phenomenon in pressure maintaining period, can not be had.
Its intracellular signaling part is constituted by electrode tip holder, electrode gland, electrode.Separation layer 13 vacuum pump formed between inner/outer tube is vacuumized by special vacuumizing joint 8, vacuumizes rear special vacuumizing joint soldering and sealing.
Installation steps are as shown in Figure 2: be 1. welded on by electrode tip holder 22 on vacuum type electrode level measuring device 21; 2. install on electrode tip holder 22 by electrode gland 23 and electrode 24, electrode tip holder adopts with electrode gland and is threaded; 3. be welded on drum 25 by vacuum type electrode level measuring device, welding manner adopts argon arc welding.
The electrode that this vacuum type electrode level measuring device uses is new-type electrode, can not be general with old-fashioned electric contact point fluviograph electrode.
This vacuum type electrode level measuring measurement device is accurate, and in the judgement drum that operations staff can be allowed correct, water level height, reduces the potential safety hazard brought because drum level measurement is inaccurate, be conducive to the normal operation of boiler.
