Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1-2, a kind of calibrating installation of airtight leak detector, including pedestal 1, detection block 2, top plate 3, locating rod 4, Clamp nut 5, positioning hole 6, gas leakage bolt 7, dust cap 8, the second gastight joint 9, the first gastight joint 10, leakage hole 11, One cavity 12, the second cavity 13, the top of the pedestal 1 have been welded to connect detection block 2, and the top of the detection block 2 is provided with top Plate 3, four turnings top of the pedestal 1 have been welded to connect locating rod 4, and four turnings of the top plate 3 are equipped with positioning Hole 6, the top of the locating rod 4 are threaded with clamp nut 5, by locating rod 4, positioning hole 6 and fastening bolt 5, The installation of top plate 3 can be easy to, and top plate 3 is clamped with detection block 2.The top of the top plate 3 has been welded to connect gas leakage bolt 7, The screw top of the gas leakage bolt 7 is connected with dust cap 8, can effectively prevent leakage hole from entering dust and shadow by dust cap Ring the gas leakage work of leakage hole.The inner side of the gas leakage bolt 7 is provided with leakage hole 11, and the side of the gas leakage bolt 7 is provided with the Two gastight joints 9, the top opposite side of the top plate 3 have been welded to connect the first gastight joint 10, the inside one of the detection block 2 Side is provided with the first cavity 12, and the inside opposite side of the detection block 2 is provided with the second cavity 13.
The detection block 2 and the interface of top plate 3 carry out edge sealing using metal sealing glue, due to detection block 2 and top plate 3 Interface carries out edge sealing using metal sealing glue, ensures sealing that detection block 2 is connected with top plate 3 with this.Described second is airtight Joint 9 is welded to connect with top plate 3.The leakage hole 11 is connected with the second cavity 13, due to the cavity of leakage hole 11 and second 13 connect, and the gas in the second cavity 13 is discharged by leakage hole 11 with this.
It should be noted that the utility model is when in use, can be by the escape pipe of airtight leak detection and the first gastight joint 10 Connection, so as to carry out airtight detection work to the first cavity 12, if air pressure is constant, airtight leak detector does not leak air then in itself Problem, conversely, airtight leak detector leaks air, problem then needs to carry out maintenance process to airtight leak detector, if airtight leak detector sheet The escape pipe of airtight leak detector is then connected by body without leakage problem with the second gastight joint 9, while opens dust cap 8, so as to right Second cavity 13 carries out air-leakage test, and because leakage hole 11 is slowly vented, airtight leak detector should detect air pressure continuous decrease And reach standard pressure, otherwise illustrate airtight leak detector inside break down, gas leakage bolt 7, the first gastight joint 10 or A failure in the second gastight joint of person 9, directly can carry out dismounting replacing to top plate 3.
