Description
Technical field
The present invention relates to omnipotent installation magnetostrictive liquid level sensor on a kind of container.
Background technology
Magnetostrictive liquid level sensor, has the features such as high, the reliable and stable and long service life of precision, is widely used in normal pressure and pressure vessel liquid level and interface level measurement.
In prior art, magnetostrictive liquid level sensor, on container, install, by the threaded hole in vessel top or flange, the vertical liquid level of sensor measuring staff is fixed in container, flexible-cable formula measuring staff magnetostrictive liquid level sensor, in order to guarantee the vertical liquid level of measuring staff, also must load onto weight at flexible-cable measuring staff bottom head.
But, actual conditions are that having on pressure and non-pressure vessel top of having do not have mounting hole or flange, some containers are because of technique or structure needs, do not allow the upper perforate in top, what have only has porose in sidewall or container bottom or allows perforate, run into this situation, cannot install and use prior art magnetostrictive liquid level sensor at container at all.
In addition, some containers, because the technological processs such as inner structure and heating tube need, effective level gauging space in container, there is up and down or around barrier, or effectively near measurement space on tank skin without mounting hole, only having of having has flange hole or allows the operating modes such as perforate on container bottom and sidewall, prior art magnetostrictive liquid level sensor also cannot be installed and used running on above-mentioned these operating mode containers.
For building the container at the inflammable and explosive scenes such as petrochemical system in, as in vessel top without ready-made mounting hole or mounting flange, because scene does not allow to get angry and easily produces the spark powerful friction operation that sets off an explosion, the magnetostrictive liquid level sensor of prior art also cannot be installed and used.
The magneto strictive sensor of prior art, can only be by mounting hole or flange in vessel top, sensor measuring staff is vertically mounted in container and is used, in vessel top, without the container of mounting hole or flange or facing to space in the mounting hole in vessel top or flange container, there is barrier, all can not install and use.
Magnetostrictive liquid level sensor of the present invention, can be arranged on mounting hole or flange and carry out liquid-level interface measurement on any position of container, any profile, any inner structure container.
To building in the inflammable and explosive on-the-spot vessel top of the systems such as petrochemical industry the container without mounting hole or mounting flange in, because scene does not allow the perforate of getting angry, prevent that spark sets off an explosion, in installation process, do not allowed power friction yet, prior art magnetostrictive liquid level sensor can not be installed and used at all on this operating mode container, but magnetostrictive liquid level sensor of the present invention, because adopting permanent strong magnetic body way to install, fixes by sensor, need not get angry, there is no power friction operation yet, can install and use at inflammable and explosive scene, therefore very great to safety in production meaning.
Summary of the invention
The object of the present invention is to provide a kind of can be at any profile (profile different), any inner structure (internal structure is different) and mounting hole or flange seat in any position of container or the magnetostrictive liquid level sensor that allows the container of installation site perforate on chamber wall to install and use, carry out liquid-level interface measurement, in installation process, need not get angry and without power friction operation, this liquid level sensor can be installed and used building on inflammable and explosive on-the-spot container.
This sensor measuring staff forms by being connected to each other three sections of the hard soft or hards that are integrated, first paragraph is electronics storehouse canned paragraph, electronics storehouse is housed on termination, on stiff rod, be useful on shell manway or flange screw thread is installed, second segment is linkage section, it is flexible-cable formula corrugated stainless steel tubing, crooked connection is installed in container for sensor, the 3rd section of stiff rod is sensor measurement section, bottom head have by universal joint, connect for permanent strong magnetic body fixing on container, on bar, cover has magnetic float, be equipped with for fixing tripod measuring section top and bottom, tripod supporting leg direction and length are all adjustable as required, the bottom head of supporting leg be equipped with by universal joint, connect for support toward fixing permanent strong magnetic body on tank skin.
While installing and using, by being installed on first paragraph measuring staff, screw thread electronics storehouse is fixed on to the hole of any position of container, on flange or tank mouth, because second segment measuring staff is flexible-cable shape, flexible clot, according to the length of sensor selected bending section in installation site in container, then by the permanent strong magnetic body on the 3rd section of measuring staff bottom head, measuring section is sitting in container bottom fixing, on adjusting, lower end fixed triangle frame supporting leg direction and adjust supporting leg length by elongated leg sleeve, permanent strong magnetic body and the chamber wall of supporting leg bottom are fixed, sensor measuring staff measuring section vertical level is fixed on to effective measuring position in container.
As everyone knows, most of large-scale with no pressure and pressure vessel is all steel manufacture, if container is stainless steel or non-ferrous material container, as long as bracket bottom termination kicker magnet has been fixed an iron (or steel) plate in container inner wall fixed position.
