Abstract
The invention provides a detection method for the quality of a welding line of a sealed container, which comprises the following steps: (1) installing an air inlet and an air outlet on the sealed container, wherein the air inlet is connected with an alcohol tank; (2) opening an air outlet valve on the alcohol tank; injecting alcohol gas into the sealed container through an air pipe, wherein pressure in the sealed container is higher than pressure outside the sealed container, and keeping the pressure for at least 30 minutes when the pressure in the sealed container reaches a set value; and (3) moving an alcohol detector along the welding line of the sealed container; if an alarm gives out an alarm in the moving process, showing that the quality of the welding line is unqualified; and if the alarm does not give out the alarm in the moving process, showing that the quality of the welding line is qualified. The detection method is simple and labor-saving and is capable of achieving the goal that the detection is successful at a time.
Description
Technical field
The present invention relates to a kind of weldquality detection method, relate in particular to a kind of airtight container weldquality detection method.
Background technology
At present, hazardous chemical container weld seam is through container is carried out water-filling or inflation mostly.Water detects, and mainly observes whether seepage of container weld seam position outside surface, but has water intaking and drainage problem; Inflation detects, and needs at container weld seam position outside surface brushing gas-development agent, and whether observation container weld seam position outside surface exists foaming, and above-mentioned two kinds the detection method spended time is long, expense is high.
Therefore, the vacuum detecting method has appearred in the prior art, the position brushing gas-development agent that need detect at container weld seam outer wall; Adopt the leaks verifying attachment; In the uncovered detection case of leaks verifying attachment, vacuumize, observe whether produce bubble, thereby determined whether leakage point.Existing leaks verifying attachment is difficult to make the inside and outside formation of uncovered detection case hermetic seal, before vacuumizing, must lean on operating personnel with defeating; And can not loose one's grip, in case loose one's grip, when vacuumizing; Gas outside the uncovered detection case causes detecting failure to internal leakage, must detect again.Detecting the such boss of weld seam especially, uncovered detection case is difficult in the weld seam position and forms hermetic seal, often need detect several times, detects both time-consuming, require great effort again, and it is not high to be detected as power.
Summary of the invention
To weak point of the prior art, the invention provides a kind of simple to operately, laborsaving, reach the successful airtight container weldquality detection method of one-time detection.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme: airtight container weldquality detection method, in this detection method, adopted alcohol container, alcohol detector and alarm, and said alcohol detector connects alarm through signal wire;
This detection method comprises the steps:
1), air intake opening and gas outlet be set on airtight container to be detected, air intake opening is connected with alcohol container through tracheae, said gas outlet is passed through vacuum pump and is connected with alcohol container;
2), the valve of giving vent to anger on the unlatching alcohol container; In airtight container, inject alcohol gas through tracheae; Show the pressure in the airtight container through the tensimeter that is provided with on the airtight container again, the pressure in the airtight container kept this pressure at least 30 minutes when being higher than the outer pressure of airtight container and reaching setting value;
3), with the weld movement of alcohol detector on the airtight container, if in moving process, alcohol detector detects the alcohol smell, alarm sends warning, then explanation is should place's welding quality defective; If in the moving process, alcohol detector does not detect the alcohol smell, alarm does not send warning, and the up-to-standard of weld seam then is described.
As a kind of preferred version of the present invention, in step 3), alcohol detector is in moving process, in case alarm sends warning, just makes mark at this welding seam leakage place.
The invention has the beneficial effects as follows: the present invention adopts and in airtight container, injects alcohol gas; Outside weld seam, adopt alcohol detector to detect, if weldquality has problem, then alcohol gas is outwards revealed through the pore in the weld seam; Alcohol detector detects this leak point, and alarm sends warning; If alarm does not send warning, explain that then weldquality is qualified.This detection method is simple, laborsaving, reaches the one-time detection success.
Description of drawings
The structural representation that Fig. 1 detects for the airtight container weldquality.
In the accompanying drawing: 1-alcohol container; 2-alcohol detector; 3-alarm; 4-air intake opening; 5-gas outlet; 6-vacuum pump; 7-airtight container; 8-tensimeter.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done explanation in further detail.
Airtight container weldquality detection method has adopted alcohol container 1 (the alcohol container internal memory contains the alcohol gas of certain pressure), alcohol detector 2 and alarm 3 in this detection method, alcohol detector 2 connects alarm 3 (as shown in Figure 1) through signal wire.
This detection method comprises the steps:
1), air intake opening 4 and gas outlet 5 be set on airtight container to be detected, air intake opening 4 is connected with alcohol container 1 through tracheae, gas outlet 5 is passed through vacuum pump 6 and is connected with alcohol container 1.
2), the valve of giving vent to anger on the unlatching alcohol container 1; In airtight container 7, inject alcohol gas through tracheae; The pressure that the tensimeter 8 that passes through to be provided with on the airtight container 7 again shows in the airtight containers 7, the pressure in the airtight container 7 kept this pressure at least 30 minutes when being higher than the pressure outside the airtight container 7 and reaching setting value.Setting value is mainly the pressure of required storage gas in the airtight container 7; When actual detected, this setting value is often than the big 0.1～1MPa of pressure of required storage gas in the airtight container 7.
3), with the weld movement of alcohol detector 2 on the airtight container 7, if in moving process, alcohol detector 2 detects the alcohol smell, alarm 3 sends warning, then explanation is should place's welding quality defective; If in the moving process, alcohol detector 2 does not detect the alcohol smell, alarm 3 does not send warning, and the up-to-standard of weld seam then is described.
In step 3), alcohol detector 2 is in moving process, in case alarm 3 sends warning, just makes mark at this welding seam leakage place, so that follow-uply carry out repair welding.After detection finishes, open air intake valve and vacuum pump 6 on the alcohol container 1, vacuum pump 6 is with in the alcohol gas suction alcohol container 1 in the airtight container 7, so that this alcohol gas is able to recycling.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the aim and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
