Description

The blind flange tightness measuring device
Technical field
The utility model relates to blind flange property testing technical field.
Background technology
Most blind flange sealings all is to adopt manual pressure test pump to test at present, its method is: blind flange and corresponding cover plate are bolted on the experiment base, make blind flange and base consist of a seal group zoarium, then add the water that certain pressure is arranged in seal, after keeping certain hour, whether observe the blind flange place has Seepage, have then judge defective, qualified without then judging, after finishing test, carry out pressure release, again bolt is backed out, take off workpiece.But this installs inefficiency, and bolt next time on each workpiece for measurement needs, and seeing when seeing if there is seepage need to examine, and still is difficult for finding during for especially little seepage, is easy to cause misjudgement, causes substandard product to come into the market.
The utility model content
The purpose of this utility model provides a kind of blind flange tightness measuring device, and it utilizes air clamper and air pressure test sealing, has not only improved the work efficiency of test, but also has improved the accuracy rate of test.
In order to solve existing problem in the background technology, the utility model by the following technical solutions: it includes worktable, tank, testing base, clamping cylinder, compression axis, fixed support, lever dolly, backstay, sliding platform;
On the described worktable tank is installed, testing base is installed in the tank, back at the worktable upper flume is equipped with fixed support, in support bracket fastened back sliding platform is installed, device has clamping cylinder above the sliding platform, and clamping cylinder is connected with lever dolly one end, and the lever dolly other end and fixed support are fixed the compression axis position, the center line of compression axis aligns with the center line of testing base, and fixed support is connected with backstay with lever dolly is middle.
Described clamping cylinder can be mobile at sliding platform.
When blind flange is carried out performing leak test, the blind flange that O-ring seal at first will be installed is placed on the testing base, then open the clamping cylinder gas admittance valve, clamping cylinder drives lever dolly moves downward compression axis, until compression axis is pressed on blind flange to be measured on the testing base, add the air that certain pressure is arranged this moment in testing base, and then add entry to tank, until blind flange is flooded, keep a period of time, have or not Bubble formation around watching blind flange, there have Bubble formation then to judge to be defective, and it is qualified then to judge without Bubble formation, after being completed, first the water in the tank is discharged, with Bas Discharged in the testing base, open at last the clamping cylinder vent valve again, clamping cylinder drives lever dolly moves upward compression axis again, then take off blind flange, finish test.
The utility model utilizes air clamper and air pressure test sealing, has not only improved the work efficiency of test, but also has improved the accuracy rate of test.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, a kind of blind flange tightness measuring device, it includes worktable 1, tank 2, testing base 3, clamping cylinder 4, compression axis 5, fixed support 6, lever dolly 7, backstay 8, sliding platform 9;
On the described worktable 1 tank 2 is installed, testing base 3 is installed in the tank 2, back at worktable 1 upper flume 2 is equipped with fixed support 6, in the back of fixed support 6 sliding platform 9 is installed, device has clamping cylinder 4 above the sliding platform 9, clamping cylinder 4 is connected with lever dolly 7 one ends, lever dolly 7 other ends and fixed support 6 are fixed compression axis 5 positions, the center line of compression axis 5 aligns with the center line of testing base 3, and fixed support 6 is connected with backstay 8 with lever dolly 7 centres.
Described clamping cylinder 4 can be mobile at sliding platform 9.
When blind flange is carried out performing leak test, the blind flange that O-ring seal at first will be installed is placed on the testing base 3, then open clamping cylinder 4 gas admittance valves, clamping cylinder 4 drives lever dolly 7 moves downward compression axis 5, until compression axis 5 is pressed on blind flange to be measured on the testing base 3, the air of certain pressure is arranged to testing base 3 interior addings this moment, and then add entry to tank 2, until blind flange is flooded, keep a period of time, have or not Bubble formation around watching blind flange, there have Bubble formation then to judge to be defective, and it is qualified then to judge without Bubble formation, after being completed, first the water in the tank 2 is discharged, with testing base 3 interior Bas Dischargeds, open at last clamping cylinder 4 vent valves again, clamping cylinder 4 drives lever dolly 7 moves upward compression axis 5 again, then take off blind flange, finish test.
The utility model utilizes air clamper and air pressure test sealing, has not only improved the work efficiency of test, but also has improved the accuracy rate of test.
