Background
At present, when the static pressure pipeline is subjected to air tightness test, a proper air tightness test connecting device is not available for connecting the pressure equipment with the upper static pressure pipeline, and the pipeline of the external pressure equipment can be sealed at the position of the static pressure pipeline only by using the traditional method, namely putty. The maintenance period is long, the cleaning is difficult, and the static pressure pipeline and the static pressure port of the equipment on the machine are easily blocked once putty enters the static pressure pipe, so that unnecessary loss is caused.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: by adopting an inflation expansion sealing method, a set of special joint device is provided, and the problem of poor sealing effect in pipeline air tightness test in the prior art is solved.
The utility model discloses carry out gas tightness test's joint in the static tube, this joint has gasbag and outside pressurization equipment connector in the part of being connected with the static tube, and mechanism UNICOM is aerifyd with the outside to this gasbag, aerify the inflation after with the static tube extrusion is connected.
The gasbag includes outside gasbag, middle part gasbag and the inside gasbag of intercommunication each other, and outside gasbag, inside gasbag are bigger than the size of middle part gasbag.
The external inflating mechanism comprises a one-way valve, an inflating airbag, an air release valve and a rubber inflating pipeline, wherein the one-way valve is arranged on the inflating airbag, and the inflating airbag is connected with the airbag through the air release valve and the rubber inflating pipeline in sequence.
The external inflating mechanism comprises a one-way valve, an inflating airbag, an air release valve and a rubber inflating pipeline, wherein the one-way valve is arranged on the inflating airbag, and the inflating airbag is connected with the external airbag through the air release valve and the rubber inflating pipeline in sequence.
The air bag surrounds the external pressurizing device connector.
The external air bag, the middle air bag and the internal air bag surround the external pressurizing equipment connector.
The outer air bag, the middle air bag and the inner air bag form a closed space after inflation, the outer air bag presses a boss at the end part of the static pressure pipe at the outer side, the middle air bag penetrates through the static pressure pipe and presses the wall of the static pressure pipe, and the inner air bag presses at the inner side of the static pressure pipe.
The gas in the air bag or the outer air bag, the middle air bag and the inner air bag is released through the valve, so that the joint is detached from the static pressure pipe.
Has the advantages that: the pipeline of the pressurizing equipment can be quickly connected with the static pressure pipe, the air tightness requirement is met, the disassembly is convenient, and the operation is easy.

Detailed Description
As shown in figure 1, the utility model discloses carry out air tightness test's joint in the static tube includes check valve 1, inflatable air bag 2, bleed valve 3, rubber gas charging line 4, outside pressurization equipment connector 5, outside gasbag 6, middle part gasbag 7 and inside gasbag 8. The rubber inflation pipeline 4 is communicated with an external air bag 6, and the external air bag 6, a middle air bag 7 and an internal air bag 8 are communicated with each other.
In use, the fitting is fitted into the static tube 9 as shown in fig. 2. The one-way valve 1, the inflatable air bag 2, the deflation valve 3, the rubber inflation pipeline 4, the external air bag 6, the middle air bag 7 and the internal air bag 8 form a closed space, the external air bag 6 is arranged outside the static pressure pipe 9, the middle air bag 7 passes through the static pressure pipe 9, and the internal air bag 8 is arranged inside the static pressure pipe 9. After the deflation valve 3 is screwed down, air can enter from the one-way valve 1 by forcibly extruding the inflatable air bag 2, the external air bag 6, the middle air bag 7 and the internal air bag 8 begin to expand, and the external air bag, the middle air bag and the internal air bag begin to expand to extrude the static pressure pipe 9, and a sealing space is formed after the static pressure pipe is expanded to a certain degree, so that the sealing effect is achieved. At this point, the external pressure equipment connector 5 is connected to the external pressure equipment and pressure can enter the static pressure tube 9 through the passage 5.
