Vacuum values between glass, this method need about 5 it is small when, time length, cost is higher；Other detection methods further include photoelastic method and move
State method, but since to the more demanding of equipment, personnel and environment, operation difficulty is larger in actual production process.
The content of the invention
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of detection vacuum glass vacuum
Quartz tube device, can reduce testing cost, shorten detection time, and have the advantages that to operate easy, visual result.
To achieve these goals, the technical solution of the utility model is：
A kind of quartz tube device for detecting vacuum glass vacuum, includes the cylindric quartz ampoule of one end open, in quartz
The wire that can be moved freely is equipped with pipe, has the graduation mark of mark vacuum degree in quartz ampoule high temperature of outer surface of high sintering.
Further, the overall diameter 3mm of the quartz ampoule, 1.82~1.84mm of interior diameter, long 65~80mm.
Further, the wire is long 5mm, the steel wire of 1.79~1.81mm of diameter.
Further, the graduation mark is divided into three groups：First group of graduation mark is one, arranged on away from 4.4~5.4mm of tube bottom it
Between；Second group of graduation mark has three, is spaced 1mm successively and is arranged at away between 26.6~32.6mm of tube bottom；3rd group of graduation mark has
Four, 1mm is spaced successively and is arranged at away between 44.5~64.5mm of tube bottom.
A kind of method using quartz tube device detection vacuum glass vacuum, comprises the following steps：
(1) under room temperature condition of normal pressure, between the quartz tube device equipped with wire is put into two blocks of glass, quartz ampoule dress
It is in diagonal position to put with the aspirating hole of glass edge, then two pieces of glass edge gaps are used glass powder materials 500~600
Sealing-in processing is carried out under DEG C high temperature；
(2) two blocks of glass are exhausted at a temperature of 300~380 DEG C and vacuumized, make pressure be down to -0.02~-
0.08MPa, in the process, wire are more than the other end away from the pressure that the close one end of tube bottom is subject to, under the differential pressure action of both ends,
It is moved near the 3rd group of graduation mark from tube bottom；Glass aspirating hole is then subjected to thawing cut-out, is fully sealed with reaching；
(3) when temperature is down to room temperature, wire is moved about at second group of graduation mark from the 3rd group of graduation mark, is shown
The vacuum of the vacuum glass reaches required value；If not reaching at second group of graduation mark, need to readjust step (2)
Evacuated pressure value, untill reaching requirement.
The beneficial effects of the utility model：
Due to just enclosing quartz tube device when producing vacuum glass, it is possible to high temperature when being vacuumized using exhaust
Condition completes the detection of vacuum at the same time, without individually being heated to glass with conventional method, thus can save a large amount of
Time and energy consumption cost；With the exception of this, vacuum glass often as some devices part, in use, when this
A little devices break down when needing detection, since the vacuum degree in glass shown by quartz tube device can be directly read, and then
Judge foregoing failure whether because vacuum glass vacuum caused by, without vacuum glass is unloaded and is sent to professional institution
It is detected, detection, the expense of maintenance can be saved indirectly.
