Description
Technical field
The utility model is related to a kind of weld seam leak detection vacuum tanks.
Background technology
Vacuum tank is the important equipment that petroleum chemical industry is used for detecting Atmosphere Storage Tank Bottom Corrosion Using leakage.Its operation principle is：
The spray fertilizer soap lye on Atmosphere Storage Tank Bottom Corrosion Using weld seam in welded joints by vacuum tank cover will vacuumize (pressure with vacuum pump inside vacuum tank
Power is -53kPa), if weld seam has leakage, there will be soap bubble generation in leak source, be seen by the observation window on vacuum tank
The leakage point on weld seam is examined, to realize the detection to Atmosphere Storage Tank Bottom Corrosion Using weld seam.
For a long time, vacuum tank uses plasticine as sealing material in detection process, has the following disadvantages：Plasticine
As sealing material observation window easy to pollute and tested storage tank bottom plate, observed in detection process so as to cause testing staff it is difficult,
Work surface is untidy；Testing staff's labor intensity is big, poor sealing performance；Detection speed is slow, detection speed about 10m/ hours.
Utility model content
Technical problem to be solved in the utility model is：Vacuum tank is in detection process using plasticine as sealing material
Material, poor sealing performance；Detection speed is slow.
Technical solution adopted by the utility model to solve its technical problems is：A kind of weld seam leak detection vacuum tank, including case
Body, has observation window, vacuum meter and vacuum pump interface on babinet, the bottom opening of babinet, for covering on weld seam to be hunted leak,
Elastic packing washer is set in the bottom of babinet, there is adhesive layer, elastic packing washer to pass through for the upper surface of elastic packing washer
The bottom adhe of adhesive layer and babinet has inverted v-shaped groove on the lower surface of elastic packing washer, has in the bottom of inverted v-shaped groove
Inverted v-shaped groove is divided into inside and outside two parts by the raised line of protrusion, and raised line is trapped in inverted v-shaped groove, makes bottom and the elastic sealing gasket of raised line
There are differences in height for the upper surface of circle.
It further limits, elastic packing washer is rubber and plastic thermal insulation board.
It further limits, the thickness of elastic packing washer is 20~30mm.
It further limits, babinet is rectangle, and the upper surface of babinet plate is transparent organic glass, and transparent organic glass is as observation
Window, vacuum meter are mounted on transparent organic glass, and vacuum pump interface is arranged in the side of babinet.
The utility model has the beneficial effects that：
1) detection operation face is clean and tidy, without any pollution；
2) testing staff's labor intensity is greatly reduced；
3) rubber and plastic thermal insulation board good seal performance, detection speed is fast, and detection speed is increased to 20m/ hours.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples；
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the elastic packing washer sectional view of the utility model；
In figure, 1. vacuum meters, 2. vacuum pump interfaces, 3. weld seams, 4. elastic packing washers, 5. inverted v-shaped grooves, 6. raised lines, 7.
Transparent organic glass, 8. Atmosphere Storage Tank Bottom Corrosion Usings, 9. babinets.
Specific implementation mode
As illustrated in fig. 1 and 2, a kind of weld seam is hunted leak vacuum tank, including babinet 9, has observation window, 1 and of vacuum meter on babinet 9
Elastic packing is arranged in the bottom of babinet 9 for covering on weld seam 3 to be hunted leak in vacuum pump interface 2, the bottom opening of babinet 9
The upper surface of washer 4, elastic packing washer 4 has adhesive layer, elastic packing washer 4 viscous by the bottom of adhesive layer and babinet 9
It closes, there is inverted v-shaped groove 5 on the lower surface of elastic packing washer 4, there is the raised line 6 of protrusion in the bottom of inverted v-shaped groove 5, by V
Shape slot 5 is divided into inside and outside two parts, and raised line 6 is trapped in inverted v-shaped groove 5, makes the upper surface of the bottom and elastic packing washer 4 of raised line 6
There are differences in height.
Replace plasticine as sealing material using elastic packing washer 4, it is reusable and can guarantee sealing effect, no
Need as using plasticine, before carrying out next section of weld seam detection after detection every time, need to use again plasticine into
Row sealing operation, substantially increases detection efficiency；Elastic packing washer 4 is by the bottom adhe of adhesive layer and babinet 9, in elasticity
After seal washer 4 is lost, the elastic packing washer 4 that can easily remove and more renew.
Meanwhile the two side of the inverted v-shaped groove 5 on the lower surface of elastic packing washer 4 can occur when vacuum tank vacuumizes
The leakproofness ensured between elastic packing washer 4 and Atmosphere Storage Tank Bottom Corrosion Using 8 is strutted outward, while being supportted in the two side of inverted v-shaped groove 5
When reaching to a certain degree, the beginning of raised line 6 is contacted with Atmosphere Storage Tank Bottom Corrosion Using 8, is formed certain support to inverted v-shaped groove 5, is prevented down V
Shape slot 5 is by complete be collapsed, while raised line 6 forms three with after the contact of Atmosphere Storage Tank Bottom Corrosion Using 8 and together with the two side of inverted v-shaped groove 5
Sealing, better ensures that sealing effect.
Elastic packing washer 4 is rubber and plastic thermal insulation board.The thickness of elastic packing washer 4 is 20~30mm, it is preferred to use 25mm
Thick B1 grade rubber and plastic thermal insulation boards.
Babinet 9 is rectangle, and the upper surface of babinet 9 plate is transparent organic glass 7, and transparent organic glass 7 is used as observation window, vacuum
Table 1 is mounted on transparent organic glass 7, and vacuum pump interface 2 is arranged in the side of babinet 9.
By actual use, detection speed is increased to 20m/ hours.
