The present invention will be described in detail with reference to the accompanying fig. 1 to 4.
Example 1:
a large-diameter valve air tightness rapid detection device comprises a bottom plate 1, wherein a fixed blind plate 4 is arranged on the bottom plate 1, and a through hole is formed in the fixed blind plate 4; the bottom plate 1 is further provided with a movable blind plate 3, and the movable blind plate 3 is close to or far away from the fixed blind plate 4 through a transmission mechanism.
The working principle is as follows:
in this technical scheme, during the use, at first confirm the type and the model of valve, then select corresponding fixed blind plate 4 and remove blind plate 3, two blind plates are all detachable connection structure, can dismantle on bottom plate 1 or from bottom plate 1 fast and get off. The diameter of the two selected blind plates is slightly larger than that of the valve, wherein a through hole is formed in the middle of the fixed blind plate 4 and is used for being connected with vacuum-pumping equipment.
After the fixed blind plate 4 and the movable blind plate 3 are arranged on the bottom plate 1, the valve core of the large-diameter valve is closed and placed between the fixed blind plate 4 and the movable blind plate 3, the movable blind plate 3 is driven by the transmission mechanism to move horizontally, the distance between the movable blind plate 3 and the fixed blind plate 4 is adjusted, the valve is pushed to move towards the fixed blind plate 4, the fixed blind plate 4 is kept still, and finally the two end diameter openings of the valve are clamped between the movable blind plate 3 and the fixed blind plate 4. At this moment, the pressure generated by the transmission mechanism is slightly larger than the fastening pressure of the two blind plates, the compression effect is realized, and the sealing of the two ends of the valve is finally completed.
After the sealing is finished, the evacuation device is connected to the through hole of the fixed blind plate 4 through the evacuation flange, and then the evacuation device is opened to evacuate and detect the interior of the valve. After the detection is finished, the valve core of the valve is opened, the pressure in the inner cavity of the valve is reduced, the transmission mechanism is adjusted to move reversely, the movable blind plate 3 is driven to move horizontally, the valve is connected with the blind plates at the two ends to be loose, the valve is taken down at the moment, and the detection is finished.

Furthermore, it is also contemplated in the embodiment that the movable blind plate 3 is movably connected to the transmission table 6 through a bolt 7. The method of bolting 7 is fast and easy to implement and the moving blind plate 3 is relatively stable when under pressure. Because the pressure generated by the motor driving the screw rod transmission 2 is slightly larger than the fastening pressure of the bolt 7, the movable blind plate 3 cannot deform and shift due to large pressure in the connection mode, and the valve can be clamped.
Example 2:
based on embodiment 1, further improve bottom plate 1 structure, make it more convenient and practical enough, improve the position of placing of valve among embodiment 1.
In this embodiment, a supporting platform 5 is arranged between the strip-shaped notch and the fixed blind plate 4. The supporting platform 5 can reduce the abrasion of the valve to the bottom plate 1 and prolong the service life of the detection device. Put the valve on supporting platform 5, the radian of supporting platform 5 itself and the circumference radian laminating of valve are convenient for better place the valve and the angle that the adjusting valve placed, and supporting platform 5 go up along being close with the bottom border of fixed blind plate 4, make valve one end directly paste on fixed blind plate 4, have reduced the time that the centre was pressed from both sides tightly, and press from both sides tightly inseparabler, promote detection efficiency.
Further, it is also contemplated in embodiments that the support platform 5 is movably connected to the base plate 1 by bolts 7. Supporting platform 5 can dismantle the connection through bolt 7, is convenient for change different supporting platform 5 according to different valve models, maintains the renewal part when also being convenient for wear and tear, prolongs whole quick detection device's life.
Furthermore, it is also contemplated in embodiments that the support platform 5 is located on the central axis of the base plate 1. The fixed blind plate 4, the movable blind plate 3 and the supporting platform 5 are all arranged on the central axis, so that the valve is clamped more tightly and has better sealing performance.
Furthermore, in an embodiment, the bottom end of the fixed blind plate 4 is movably connected with the transmission table 6 through a bolt 7. The method for connecting the bolts 7 is quick and easy to realize, and the fixed blind plate 4 is more stable and cannot deform and shift due to the pressure from the top of the valve.
In conclusion, the utility model provides the rapid air tightness detection device for the large-diameter valve, which can reduce the detection time and enable the detection method to be faster.
The present invention has been described in detail with reference to the above examples, but the description is only for the preferred examples of the present invention and should not be construed as limiting the scope of the present invention.
