Abstract
The utility model discloses an air tightness inspection device for a riser tube, and the air tightness inspection device is used for inspecting air tightness of the riser tube. The air tightness inspection device comprises an upper flange, a lower flange and a connecting screw rod connecting the upper flange and the lower flange. The upper flange is connected in a sealing manner to an end of the riser tube via an upper sealing device. The lower flange is connected in a sealing manner to the other end of the riser tube via a lower sealing device. An air inflation hole is disposed either in the upper flange or in the lower flange. The air inflation hole communicates with an air inflation tube line. According to the utility model, the two ends of the riser tube are sealed via the upper flange, the upper sealing device, the lower flange and the lower sealing device. Compressed air is inflated into the riser tube via the air inflation hole and maintains compressed. If leakage occurs to the riser tube, the pressure goes down; otherwise, the riser tube can work properly; and if leakage occurs, the riser tube is abandoned directly and purchasing suppliers are fed back.

Summary of the invention
In view of this, the utility model provides a kind of stalk airtight testing fixture, to check whether stalk leaks.
For realizing the above object, the utility model provides following technical scheme:
The airtight testing fixture of a kind of stalk, for checking the impermeability of stalk, comprising:
Upper flange, described upper flange is tightly connected by one end of upper sealing device and described stalk;
Lower flange, described lower flange is tightly connected by the other end of lower sealing device and described stalk, offers air-filled pore on one in described upper flange and described lower flange, and described air-filled pore is communicated with loading line;
Connect the connecting screw rod of described upper flange and described lower flange.
Preferably, in the airtight testing fixture of above-mentioned stalk, described upper sealing device and described lower sealing device are rubber sealing device.
Preferably, in the airtight testing fixture of above-mentioned stalk, between described loading line and described air-filled pore, be in series with switch valve.
Preferably, in the airtight testing fixture of above-mentioned stalk, between described loading line and described air-filled pore, be in series with pressure-regulating valve.
Preferably, in the airtight testing fixture of above-mentioned stalk, between described loading line and described air-filled pore, be in series with detected pressures table.
Technical scheme from the above can find out, the airtight testing fixture of stalk that the utility model provides, carries out shutoff by upper flange, upper sealing device, lower flange and lower sealing device to the two ends of stalk.Then in stalk, pour pressure gas pressurize by air-filled pore, leak if stalk exists, pressure can decline so, otherwise illustrates that this stalk can normally use, and if any leakage, directly scraps or feed back procurement supplier.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below by embodiment or prior art are retouched described in the accompanying drawing of required use be briefly described, apparently, the accompanying drawing of retouching below in described is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
