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, the features such as with high precision, reliable and stable and long service life, is widely used in normal pressure
With pressure vessel liquid level and interface level measurement.
In the prior art, magnetostrictive liquid level sensor, installs on container, is by the screwed hole or method in vessel top
Orchid, sensor measuring staff vertical fluid level is fixed in a reservoir, flexible-cable formula measuring staff magnetostrictive liquid level sensor, in order to ensure to survey
Bar vertical fluid level, it is necessary to which head loads onto weight in flexible-cable measuring staff bottom.
But, actual conditions be have have pressure and non-pressure vessel top on be fitted without hole or flange, some containers are because of technique
Or structure needs, and does not allow to push up perforate, there is hole on the only side wall or container bottom having or allow perforate, run into this feelings
Condition, cannot install and use prior art magnetostrictive liquid level sensor in container at all.
In addition, some containers, because the technical process such as internal structure and heating tube need, effective level gauging is empty in container
Between, up and down or surrounding has a barrier, or effectively measurement space is nearby on tank skin without mounting hole, in the only container bottom and side wall having
There is flange hole or allow the operating modes such as perforate, prior art magnetostrictive liquid level sensor cannot also hold above-mentioned these operating modes are run into
Installed and used on device.
For the container for having built the inflammable and explosive scene such as petrochemical system in, without ready-made mounting hole or peace such as in vessel top
Dress flange, sets off an explosion the friction operation of strength because scene does not allow to get angry and be also easy to produce spark, and the mangneto of prior art is stretched
Contracting liquid level sensor cannot also be installed and used.
The content of the invention
Can be in any profile it is an object of the invention to provide one kind（Profile is different）, any internal structure（Internal structure
It is different）And mounting hole or flange seat are in any position of container or allow the container of installation site perforate on the wall to install and use
Magnetostrictive liquid level sensor, carry out liquid-level interface measurement, in installation process, without get angry and without power friction operate,
The liquid level sensor can be installed and used having built on inflammable and explosive live container.
The sensor measuring staff is constituted by interconnecting hard soft or hard three sections be integrated, and first paragraph is electronics storehouse canned paragraph, end
Electronics storehouse is housed on head, is had on stiff rod for toward screw thread is installed on shell manway or flange, second segment to be linkage section, is flexible-cable
Formula corrugated stainless steel tubing, bending connection is installed for sensor in container, and the 3rd section of stiff rod is sensor measuring section, bottom head
Have by universal joint connection for toward permanent strong magnetic body fixed on container, magnetic float being cased with bar, measuring section upper end is with
Equipped with for fixed tripod, tripod supporting leg direction and length are adjustable all in accordance with needing, and the bottom head of supporting leg is equipped with logical at end
Cross universal joint connection for support toward fixed permanent strong magnetic body on tank skin.
When installing and using, electronics storehouse is fixed on any position of container by installing screw thread on first paragraph measuring staff
In hole, flange or tank mouth, due to second segment measuring staff be flexible-cable shape, flexible clot, according to sensor in container installation site
The length of selected bending section, then by the permanent strong magnetic body on the 3rd section of measuring staff bottom head, measuring section is sitting in container bottom
It is fixed, by adjusting upper and lower end fixed triangle frame supporting leg direction and adjusting supporting leg length by elongated leg sleeve, by supporting leg bottom
Permanent strong magnetic body and the chamber wall at end are fixed, and sensor measuring staff measuring section vertical level is fixed in container into effectively measurement position
Put.
It is well known that it is all steel manufacture without pressure and pressure vessel that major part is large-scale, such as container is stainless steel or non-ferric
Material material container, as long as support bottom head kicker magnet fixes one block of iron in container inner wall fixed position（Or steel）Plate is just.
Beneficial effects of the present invention
The magneto strictive sensor of prior art, can only be by vessel top upper installing hole or flange, by sensor measuring staff
It is vertically mounted in container and uses, mounting hole or flange on container or opposite vessel top without mounting hole or flange in vessel top
There is barrier in space in container, can not all install and use.
Magnetostrictive liquid level sensor of the invention, can be arranged on mounting hole or flange in any position of container, any outer
Liquid-level interface measurement is carried out on shape, any internal structure container.
To having built the container without mounting hole or mounting flange in the inflammable and explosive live vessel top of the systems such as petrochemical industry in, due to
Scene does not allow perforate of getting angry, and prevents that spark sets off an explosion, and power friction, prior art are also not allow in installation process
Magnetostrictive liquid level sensor can not be installed and used on this operating mode container at all, but magnetostrictive liquid level of the invention is sensed
Device, is installed using permanent strong magnetic body method due to sensor and fixed, and is operated without getting angry, also without power friction, can be inflammable
Explosive in-site installation is used, therefore very great to safety in production meaning.
