Abstract
An adjustable high-pressure generator liquid-level electrode device is characterized in that the upper part of a liquid-level probe (5) of the high-pressure generator liquid-level electrode is sleeved with a pipe-shaped sealing ring (1) which is externally provided with a positioning bolt (3); the upper part of the positioning bolt is connected with a clamp sealing bolt (2). The utility model has the advantages of simple structure, flexible adjustment, little material consumption and low cost.
Description
Technical field
The invention belongs in the lithium-bromide absorption-type refrigerating machine group, high pressure generator is the highest parts of temperature, particularly a kind of adjustable high-voltage generator level electrode device
Background technology
In the lithium-bromide absorption-type refrigerating machine group, high pressure generator is the highest parts of temperature, also is one of most important parts (reaching as high as 160 ℃).Its structure is: the interior high-temperature steam of copper pipe is as the outer lithium-bromide solution (steam type) of thermal source heating tube, or high-temperature flue gas heats the outer lithium-bromide solution (direct combustion type) of steel pipe as thermal source in the steel pipe.If the high pressure generator liquid level is crossed the low situation that pipe will occur dryouting, equipment is worked the mischief.And if liquid level is too high, then cause the generation effect bad, influence the refrigerating capacity of unit.So the high pressure generator liquid level is to need strict control
The liquid level control of high pressure generator realizes by variable frequency pump and level electrode.Its principle is: the current liquid level of level electrode induction high pressure generator also passes the signal to controller, sends instruction by controller, changes the frequency of variable frequency pump, realizes the control to the high pressure generator liquid level.So, the depth position of level electrode probe (being the length of probe) be directly connected to high pressure generator work normally whether.
Traditional level electrode is the version that adopts as shown in Figure 1, and selected brand is a quality Japan OMRON product preferably.Its version is: level electrode is fixed on the pipe collar of fluid level controller by the location plug screw, porcelain bushing comes crust (the being the zero line position) insulation of level probe and fluid level controller, owing to fix between level probe and the bolt,, liquid need pre-determine so being the length of probe.In the debug process of reality, this version can be brought a series of problems:
1. because the temperature of high pressure generator and pressure are constantly to change, normal liquid level is difficult to pre-
Decide earlier, the concrete condition that can only look field adjustable is fixed.So predetermined probe
It is just right that length is difficult to accomplish.
2. because the requirement of the vacuum tightness of lithium bromide refrigerator is very high, outside allowing anything but in principle
Boundary's air enters unit inside.And if gesture is adjusted at the scene to the length of probe
Must cause great destruction to the vacuum of unit, influence the life-span of unit.
Summary of the invention
Technical matters to be solved by this invention is: a kind of adjustable high-voltage generator level electrode device is provided
Technical scheme of the present invention is:
A kind of adjustable high-voltage generator level electrode device is characterized in that: level probe (5) top at the high pressure generator level electrode is with tubulose O-ring seal (1), and O-ring seal has bolt (3) bolt top to be connected with card envelope bolt (2) outward.
Effect of the present invention is:
This apparatus structure is simple, adjusts flexibly, and consumptive material is few, and cost is low.

Embodiment
This device is made up of five parts as shown in Figure 2, and its principle of work is such: O-ring seal (1) is made by polytetrafluoroethylmaterial material, can be high temperature resistant more than 200 ℃.By bolt (3) O-ring seal is positioned on the liquid level gauge seat (4) during installation, tights a bolt simultaneously, make the bolt bottom compress the fin of O-ring seal, realize sealing for the first time.Level probe (5) is inserted in the O-ring seal, to block envelope bolt (2) again tightens, because the material of O-ring seal is a teflon, certain elasticity is arranged, so in tightening card envelope bolt, O-ring seal tightly is squeezed on the level probe, has realized sealing for the second time, has also guaranteed the fixing of level probe depth position simultaneously.By twice sealing, just will completely cut off inside and outside the unit like this, effectively guaranteed the vacuum tightness of unit, realized the insulation between level probe and the fluid level controller crust simultaneously.
In actual debug process, when finding that level probe depth position is undesirable, only need unscrew card and seal bolt, can adjust the depth position of level probe, and needn't whole plug screw be extracted, thereby cause the sudden and violent sky of unit as accompanying drawing two.
This apparatus structure is simple, adjusts flexibly, and consumptive material is few, and cost is low, can realize processing in the factory.
