Abstract
A vacuum box leak detection device belongs to the field of instruments and equipment. The utility model aims to provide a convenient, practical and efficient vacuum box leak detection device. The key points of the technical scheme are as follows: a vacuum box is generally made of metal material and manufactured into a rectangular box body; one end of a side surface of the box body is arc-shaped, so that the edge of a cylinder-shaped container can be detected conveniently; the box body is provided with a jacket, so that a sealing piece can be mounted at the bottom of the box body conveniently; a piece of transparent visible glass is mounted on the outer surface of the upper part of the box body and is required to have good transparency and be capable of bearing the suction force of vacuum; the glass and the box body are mounted in a sealing manner; and a hole is formed on the side surface of the box body so as to allow a vacuum gauge and a connecting pipe to be mounted. The vacuum box leak detection device has the advantage of facilitating production and improvement on observation accuracy, and is applicable to containers and equipment requiring vacuum box leak detection.
Description
Technical field
The present invention relates to a kind of vacuum tank leakage detection apparatus, belong to the instrument and equipment field.
Technical background
At the tun that does not allow seepage such as petroleum storage tank, liquid oxygen, liquid nitrogen storage tank when making and check, leak test is done in requirement, but when adopting air-tight test, general gas is at internal tank, the base plate position can't be checked, so adopt vacuum tank to check.The present vacuum tank that uses, the disposable sealing of the employing that has, the employing that has manually vacuumizes, and effect is relatively poor.
Summary of the invention
The objective of the invention is: make a kind of convenience, practicality, vacuum leak detector efficiently.
Technical scheme of the present invention is as follows: because vacuum tank mainly is the weld seam of the large-scale flat container of check, so vacuum tank generally selects for use metal material to make rectangular box, casing side one end is an arc, be convenient to check the edge of cylindrical vessel, casing adopts chuck, is convenient to bottom half seal is installed.Seal can adopt multiple shapes such as straight flange or circular arc as required, so that closely contact with tested position, prevents that air from entering.Outside surface on casing stays groove, and transparent visual glass is installed.Glass requires the transparency good, can also bear the suction of vacuum.Glass and casing adopt sealing that encapsulant such as glass cement etc. are installed.In the casing side, vacuum meter and adapter are installed in perforate, and adapter and vacuum pump adopt to be tightly connected and preferably adopt rapid-acting coupling, and threeway and valve are installed on taking over.The height of vacuum tank and length are made with field condition as required, generally should adopt bigger volume, to keep the stable of vacuum tightness, about the wide 200mm of the high 250mm of generally long 600mm, promptly are convenient to observe and handled easily.The attacker also can be installed on frame to be convenient to move.
Advantage of the present invention is: the accuracy that helps producing and improving observation.
The present invention is applicable to: the container, the equipment that need the vacuum tank leak detection.

1: casing 2: chuck 3: glass 4 seals 5: take over 6: threeway 7: sealing adaptor 8: tensimeter
Embodiment
At first according to required form seal 4 is installed in the casing 1 and the bottom of chuck 2, again vacuum pump is connected with vacuum tank by sealing adaptor 7 and adapter 5, then tested position being coated with suds is placed on the vacuum tank leakage detection apparatus on the tested position, start vacuum pump, observe pressure vacuum gauge 8, termination of pumping when reaching predetermined vacuum level, observe by glass 3, as be coated with the suds position and have bubble to produce, illustrate that then extraneous air is inhaled into vacuum tank, whether check seepage with this, checking finishes opens the valve bubbling air inspection that threeway 6 connects and finishes.
Claims (1)
1. a vacuum tank leakage detection apparatus comprises adapter, threeway, vacuum meter, it is characterized in that: select for use metal material to make rectangular box, casing side one end is an arc, and casing adopts chuck, and the outside surface on casing stays groove, and transparent visual glass is installed.
