Abstract
The utility model discloses a dry type aligning device for a low temperature gas cylinder liquid level meter. The dry type aligning device is characterized in that the dry type aligning device comprises a vertical back panel, an upper port platform, a lower port platform and a length mark, wherein the rear end of the upper port platform is fixedly mounted at the upper part of the vertical back panel; a liquid level meter hanging port is arranged at the front part of the upper port platform; the rear end of the lower port platform is mounted at the lower part of the vertical back panel through a sliding chute; a floating rod hanging port is arranged at the front part of the lower port platform; and the length mark is arranged on the vertical back panel in the corresponding position of the to-be-aligned liquid level meter. The dry type aligning device can be used for checking, maintaining and aligning a spring, a floating rod, a meter head and the like for the low temperature gas cylinder liquid level meters which have different structures and used in different media, has the advantages of simple and reasonable structure, convenience for use and the like, and is especially suitable for special equipment safety and supervision inspection departments to use.
Description
Technical field
The utility model relates to a kind of verifying attachment of level meter, and the verifying attachment of the level meter of installing and using on particularly a kind of low temperature cylinder belongs to the level meter field.
Background technique
Cryogenic insulated cylinder (being commonly called as low temperature cylinder, Dewar vessel) but be a kind of portable extraordinary gas cylinder of repeated charging, be mainly used in cryogenic liquides such as storing liquid nitrogen, liquid oxygen, liquid argon, LNG Liquefied natural gas.In order to ensure the safety of cryogenic insulated cylinder, must strictness prevent the liquid gas overfilling, otherwise explosion hazard is very big.In the low temperature cylinder explosive accident, overfilling causes the ratio of low temperature cylinder physical property blast very big, these low temperature cylinders mostly remain static before blast, be not impacted and shake, mainly be to be subjected to Temperature Influence, superpressure in the bottle, expire the bottle back interior liquid gas of bottle along with temperature raises, its volumetric expansion, then, expand and promptly transfer compression to, because the compressibility of liquid is very little, so force value is directly proportional with the expansion coefficient of splendid attire medium, is inversely proportional to compressibility coefficient, just because of the compressibility coefficient of liquid is very little, and expansion coefficient is relatively big, and (differing 2 orders of magnitude) is so the rising of low temperature cylinder internal pressure is very surprising, so the level meter on the low temperature cylinder is controlled the filling weight size to operator, be a good supervisory device.
The level meter of on low temperature cylinder, installing and using, the long float rod type level meter of main use, the fly rod diameter has φ 8, φ 10, φ 12 etc., length has plurality of specifications such as 1200,1400,1500, and gauge outfit also will have nothing in common with each other according to the proportion of media such as liquid nitrogen, liquid oxygen, liquid argon, LNG Liquefied natural gas is different.At the level meter of above-mentioned multiple different size, in to the low temperature cylinder third pary certification, also must carry out the inspection and maintenance adjustment to spring, fly rod and the gauge outfit of the different level meters of various structures on the low temperature cylinder.
Summary of the invention
The purpose of this utility model is to design a kind of simple and reasonable for supervision and inspection on safety department, easy to use, can carry out the dry type debugging apparatus that spring, fly rod and gauge outfit are carried out the low temperature cylinder level meter of inspection and maintenance adjustment to various different structures and the low temperature cylinder that in different medium, uses level meter.
The dry type debugging apparatus of low temperature cylinder level meter of the present utility model, its structure comprises vertical back-panel, platform suitable for reading, end opening platform and length mark, described platform suitable for reading rear end is packed in vertical back-panel top, platform suitable for reading front portion is provided with level meter and hangs mouth, end opening platform rear end is installed in the vertical back-panel bottom through sliding-groove, and end opening platform front portion is provided with fly rod hanging mouth, and length mark is located at and treats on the vertical back-panel of school level meter corresponding position.
Detect for the ease of the float rod type level meter to different length, the height of described vertical back-panel is elected 1800～2000mm as, and the height of platform suitable for reading is elected 1600～1800mm as, and the sliding-groove height of end opening platform is elected 300～800mm as.
The dry type debugging apparatus of low temperature cylinder level meter of the present utility model, during use, the level meter that will debug hangs on the platform suitable for reading, make level meter be in free state, the level meter head is loaded onto the gauge outfit that matches, and observes the spring on the gauge outfit display device fly rod, and whether parts such as fly rod parameter request up to specification, as find that individual part damages the renewal part post debugging.Carry with have gentle hands earlier, upwards rise the level meter fly rod and check that indicator indicates whether flexibly, whether make zero correct, defective as macroscopic examination, will unscrew the level meter retaining screw, the method that employing puts in, pulls out, adjust level meter, make it to make zero, pointer position is accurate, again with the slight more upper and lower pulling level meter fly rod of hand, meter pointer should be followed rotation, no clamping stagnation, the meter pointer position indication of liquid level is qualified accurately, can check the perpendicularity of level meter easily with the fly rod position in the hanging mouth that is lifted on the end opening platform.Carry out the inspection and maintenance adjustment so can carry out spring, fly rod and gauge outfit etc. to various different structures and the low temperature cylinder that in different medium, uses level meter, have simple and reasonable, advantage such as easy to use is particularly suitable for special equipment supervision and inspection on safety department equipment and uses.
