Abstract
The utility model belongs to full static pressure system air-tight test technique, concretely relates to carry out air-tight test's joint outside the total tube pressing. At present, when a full-pressure pipeline air tightness test is carried out, a proper air tightness test connecting device is not available, the pressure equipment is connected with an onboard full-pressure pipeline, and the pipeline of external pressure equipment can be sealed at the full-pressure pipeline only by using a traditional method, namely putty. The maintenance period is long, the cleaning is difficult, and once putty enters the full-pressure pipe, the full-pressure pipeline and the full-pressure port of the equipment on the machine are easily blocked, and unnecessary loss is caused. The utility model discloses the shell that connects has sealed gasbag for single-ended open-ended cast structure in the shell inner wall, has the outside pressure equipment connector with the mechanism of aerifing of sealed gasbag UNICOM, with shell inner chamber UNICOM at the outer terminal surface in shell bottom. Can be quick be connected test pipeline and total pressure pipe to satisfy the gas tightness requirement, it is convenient to dismantle, easily operation.
Description
Technical Field
The utility model belongs to full static pressure system air-tight test technique, concretely relates to carry out air-tight test's joint outside the total tube pressing.
Background
At present, when a full-pressure pipeline air tightness test is carried out, a proper air tightness test connecting device is not available, the pressure equipment is connected with an onboard full-pressure pipeline, and the pipeline of external pressure equipment can be sealed at the full-pressure pipeline only by using a traditional method, namely putty. The maintenance period is long, the cleaning is difficult, and once putty enters the full-pressure pipe, the full-pressure pipeline and the full-pressure port of the equipment on the machine are easily blocked, and unnecessary loss is caused.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the utility model discloses an aerify sealed method of inflation provides the joint that carries out gas tightness test outside the total-pressure pipe, solves the gas leakage problem of prior art when the pressurization is connected to the total-pressure pipe.
The utility model discloses carry out gas tightness test's joint outside the total tube, the shell that should connect has sealed gasbag for single-ended open-ended cast structure in the shell inner wall, has the outside pressurization equipment connector with the mechanism of aerifing of sealed gasbag UNICOM, with shell inner chamber UNICOM at the outer terminal surface in shell bottom.
The sealing air bag is sleeved on the outer side of the full-pressure pipe, and the full-pressure pipe is sealed and clamped after being inflated.
The inflation mechanism comprises a one-way valve, an inflation airbag, a deflation valve and a rubber inflation pipeline, wherein the inflation airbag is provided with the one-way valve and is communicated with the sealed airbag through the deflation valve and the rubber inflation pipeline in sequence.
The air is inflated into the sealed envelope by squeezing the inflated envelope.
And the external pressurizing equipment is connected to the external pressurizing equipment connecting head.
The pressurized gas enters the full-pressure pipe through the channel.
Releasing the relief valve releases the pressure within the sealed bladder.
Has the advantages that: can be quick be connected test pipeline and total pressure pipe to satisfy the gas tightness requirement, it is convenient to dismantle, easily operation.
Drawings
FIG. 1 is a schematic structural view of the joint of the present invention;
figure 2 is the utility model discloses the joint installs the schematic diagram on the total pressure pipe.
Detailed Description
As shown in figure 1, the joint for performing the air tightness test outside the full-pressure pipe is hereinafter referred to as the joint, and comprises a one-way valve 1, an inflatable air bag 2, a deflation valve 3, a rubber inflation pipeline 4, a sealed air bag 5, a shell 6 and an external pressurizing equipment connector 7. After the check valve 1, the inflatable air bag 2, the deflation valve 3 and the rubber inflation pipeline 4 are sequentially connected, the rubber inflation pipeline 4 penetrates through the shell 6 to be communicated with the internal sealed air bag 5.
In use, the fitting is driven into the full pressure tube as shown in figure 2. The check valve 1, the inflatable air bag 2, the deflation valve 3, the rubber inflation pipeline 4 and the sealed air bag 5 form a closed space, when the deflation valve 3 is screwed down, air of the inflatable air bag 2 is extruded forcefully and can enter from the check valve 1, the air enters the sealed air bag 5 along the rubber inflation pipeline 4, the sealed air bag 5 begins to expand, and the full-pressure pipe 8 is clamped after the air expands to a certain degree to form a sealed space, so that the sealing effect is achieved. At this time, the external pressurizing equipment connector 7 is connected to the external pressurizing equipment, and the pressure can enter the full-pressure pipe 8 through the passage 7.
