Description
Technical field
The utility model relates to fire extinguisher cylinder valve leak detection field, in particular to a kind of cylinder valve leakage detecting structures.
Background technique
For specific use gas cylinder, the airtight test after filling is most important, and such as firefighting bottle, the time to be set is long, and one
A round of visits is 3 years, if gas cylinder valve leaks, it will lead to serious consequence, bring adverse effect to enterprise, institute
Must strictly hunt leak after cylinder filling.
Also, the cylinder valve leak detection before filling is also a more important step, and hunts leak and corresponding leakage detecting structure is then needed
It realizes.
Utility model content
The utility model can effectively be directed to fire fighting gas to solve the above problems, provide a kind of cylinder valve leakage detecting structure
The simulation of cylinder valve is hunted leak, and judges whether cylinder valve leaks by smelling quick instrument, guarantees yields.
In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of cylinder valve leakage detecting structure, including work
Platform, mixing steel cylinder, valve installing port are integrated in the workbench, and mixing steel cylinder is connected to nitrogen inlet duct road and signal piping, examines
Test tube road is equipped with the first shut-off valve, the second shut-off valve and third shut-off valve, and valve installing port is cut in the second shut-off valve and third
It is only connected between valve with signal piping, third shut-off valve and the first shut-off valve are connected to blowdown piping, and nitrogen inlet duct road is equipped with
4th shut-off valve and check valve, valve installing port and valve body silk mouth threaded connection place to be measured, which are equipped with, smells quick instrument.
Further, pressure gauge, and the second shut-off valve and third cut-off are equipped on nitrogen inlet duct road and signal piping
Valve also is provided with pressure gauge.
Further, nitrogen inlet duct road access mixing bottom of steel cylinder, signal piping access top.
Further, mixing steel cylinder is medicament mixing steel cylinder.
In conclusion the utility model has following advantages:
The utility model can effectively hunt leak for the simulation of fire fighting gas cylinder valve, by smelling whether quick instrument judges cylinder valve
It leaks, guarantees yields.
Detailed description of the invention
Fig. 1 is the structure principle chart of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
Embodiment 1:
A kind of cylinder valve leakage detecting structure, including workbench are integrated with mixing steel cylinder 1, valve installing port 2 in workbench, wherein
Mixing steel cylinder 1 is medicament mixing steel cylinder, and for the difference of fire fighting gas, interior medicament is also different.
Specifically, as shown in Fig. 1, mixing steel cylinder 1 is connected to nitrogen inlet duct road 11 and signal piping 12, wherein nitrogen
Air inlet pipeline 11 accesses 1 bottom of mixing steel cylinder, and signal piping 12 accesses top, thus when nitrogen enters, it can be effective
Ground mixes medicament.
Wherein, signal piping 12 is equipped with the first shut-off valve 3, the second shut-off valve 4 and third shut-off valve 5, valve installing port 2
It is connected between second shut-off valve 4 and third shut-off valve 5 with signal piping, and is additionally provided with pressure gauge therebetween, third shut-off valve 5 and
One shut-off valve 3 is connected to blowdown piping 6, and blowdown piping is used to discharge the pressure in mixing steel cylinder.
With continued reference to attached drawing 1, nitrogen inlet duct road 11 is equipped with the 4th shut-off valve 7 and check valve 8, for controlling nitrogen
Into.
Valve installing port 2 and valve body silk mouth threaded connection place to be measured, which are equipped with, smells quick instrument, for detecting whether cylinder valve leaks.
With further reference to attached drawing 1, pressure gauge is equipped on nitrogen inlet duct road 11 and signal piping 12, pressure gauge can have
Pressure in effect monitoring pipeline, carries out under suitable pressure to control detection.
Specifically, valve body to be measured accesses valve installing port 2, and connects and smell quick instrument, subsequent second shut-off valve in detection process
4, third shut-off valve 5, the 4th shut-off valve 7 and check valve 8 are opened, and are detected, if there is leakage, are then smelt under suitable pressure
Quick instrument alarm.
After the completion of detection, third shut-off valve 5 and the first shut-off valve 3 are opened, closes other valves, reduces loine pressure, and
Take out valve body to be measured.
And when mixing steel cylinder liquid level is lower, the first shut-off valve of opening, the reduction pressure in the bottle to 1MPa, then with 2.5MPa's
Pressure injects medicament, completes supplement.
Above embodiment is only to illustrate the technical ideas and features of the present invention, and its object is to allow be familiar with this skill
The people of art can understand the content of the utility model and implement accordingly, not limit the protection scope of the present invention.
It is all according to the spirit of the present invention substantially equivalent transformation that is done or modification, should all cover the protection scope of the utility model it
It is interior.
