Background technology
China uses nondestructive test, non-destructive inspection in mechanical and electric equipment installation engineering for weld seam detection at present
It tests, including appearance test, compactness inspection and nondestructiving inspecting test.Appearance test is based on direct visual perception, when necessary
It is checked using 5-10 times of magnifying glass, visual examination is primarily to find the surface defect of welding point.Compactness is examined, often
Detection method has：Hermeticity experiment, ammonia experiment, kerosene experiment etc., but easy experiment is used in Practical Project construction
Device, weld inspection method is not rigorous, job specfication requirement is often not achieved, and then influence the construction quality of storage tank, there are matter
Measure security risk.Nondestructiving inspecting test, be using the methods of inspection such as infiltration, magnetic powder, ultrasonic wave, ray, but this with method often
Complicated, valuable component is needed, construction cost is made to increase.
Invention content
The technical problem to be solved by the present invention is to provide a kind of at low cost, accurate storage tank bottom plate weld joint vacuum examination of detection
Experiment device.
The technical scheme is that：A kind of storage tank bottom plate weld joint vacuum experimental rig, including framework, the shape of the framework
Shape is cuboid, which is characterized in that is equipped with opening at the top and bottom of the framework, observation window, institute are equipped at the top of the framework
Two long side surfaces for stating framework are equipped with pressure vacuum gauge, are respectively mounted control valve I before the pressure vacuum gauge, and the two of the framework
A short sides are respectively equipped with vacuum pump interface and air inlet, and the vacuum pump interface and air inlet are equipped with control valve II.
Further, the framework is welded for angle steel, and the framework bottom is equipped with the extension of outside bending, the extension bottom
Portion is equipped with flexible barrier material, and the observation window is tempered glass, and the upper end of the framework is equipped with fixed bearing platform, the tempering glass
Glass is buckled between framework and fixed bearing platform, is sealedly and fixedly connected with framework and fixed bearing platform.
Further, described two pressure vacuum gauges are diagonally arranged.
Further, the flexible barrier material is clay.
Further, the framework inner-wall spraying white paint.
Advantageous effect：
Framework can be buckled on storage tank bottom plate, and using compressed air as work air source, utilize penetrating for gas flow at high rates
Suction acts on, and the air in framework is taken out of, generates parital vacuum, under the premise of ensureing the leak detection of tank bottom weld seam, improves tank bottom
The vacuum leak hunting progress of weld seam, while the double pressure gauges of diagonal setting can be verified, while can be during vacuumizing in real time
Air pressure change in accurate observation framework improves the accuracy of experiment, and the personnel of hunting leak can penetrate observation window and observe weld seam
Leakage situation, so, tank bottom weld joint vacuum of the invention detection box is not only simple in structure, is easy to use, and reduces leak detection
The labor intensity of personnel, improves work efficiency, can accurately detect whether tank bottom weld seam leaks.
