Description
Technical field
The utility model relates to fire extinguisher production technical field, more particularly, to a kind of for fire extinguisher air-leakage test
It checks head and checks cover.
Background technique
The effect of in order to guarantee fire extinguisher, is filled with a certain amount of gas usually before factory into tank body, and promoting the circulation of qi of going forward side by side is close
Property detection.It is that fire extinguisher is stored to a period of time in warehouse when more early, is then to judge fire extinguisher by observation pressure gauge
No gas leakage.This test format period is longer, cannot judge rejected product in time, and needs to occupy a large amount of place and people
Power.At present relatively mostly use water testing machine carry out leakage detection, i.e., fire extinguisher is put into pond, by observation bubble shape to determine whether
Gas leakage.Due to needing that fire extinguisher is fully immersed in water, this mode equally not only needs biggish place, it is also necessary to
More water；In addition, being usually unable to which fire extinguisher leakage is accurate judgement be when existing simultaneously multiple fire extinguishers in pond
Gas causes rejected product missing inspection to happen.
Summary of the invention
To solve the above-mentioned problems, the utility model provides a kind of inspection head for fire extinguisher air-leakage test, simultaneously
A kind of inspection cover for fire extinguisher air-leakage test is provided, can specifically take following technical proposals:
Inspection head described in the utility model for fire extinguisher air-leakage test, it is saturating including what is be connected with vacuum device
Bright observation is covered, and is provided with the water-blocking component being connected with automatic resetting mechanism in the transparent observing cover.
It is provided with the stepped hole being connected with vacuum device at the top of the transparent observing cover, is provided with position in transparent observing cover
Support frame below the stepped hole；The water-blocking component includes being slidably arranged in stepped hole macropore, lower surface with close
The valve block of seal, the valve rod connected on the valve block sequentially pass through the aperture of stepped hole and the centre bore of support frame as described above and downward
Extend, the valve stem end is provided with retaining ring；The automatic resetting mechanism includes the compressed spring being threaded through on the valve rod, institute
Compressed spring is stated between support frame and the retaining ring.
Inspection cover described in the utility model for fire extinguisher air-leakage test, including the inspection head and with its phase
The cover that draws water for being socketed in outside fire extinguisher even, the lower edge of the cover that draws water are located at the liquid level in water testing machine pond or less.
The cover that draws water is connected through a screw thread with head is checked.
Described one end that cover is connected with inspection head of drawing water is pyramidal structure.
The snap-gauge matched with grasping mechanism is provided on the cover that draws water.
The inspection head and the cover that draws water are arranged in groups, and the cover that draws water is connected by connecting plate.
The utility model structure is simple, easy to use, not only can quickly determine the fire extinguisher of gas leakage, improves leakage detection detection
Efficiency and accuracy, and the water level in water testing machine pond can be reduced, reduce leakage detection water consumption, facilitate the cleaning in pond.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model checks head.
Fig. 2,3 be Fig. 1 sectional view.
Fig. 4,5 be the utility model inspection cover structural schematic diagram.
Specific embodiment
Inspection head described in the utility model for fire extinguisher air-leakage test, it is saturating including what is be connected with vacuum device
Bright observation is covered, and is provided with the water-blocking component being connected with automatic resetting mechanism in the transparent observing cover.Specifically, as shown in Figure 1-3,
Transparent observing cover 1 is the tubular structure made of the hard transparent materials such as ABS, and top is the ladder being connected with vacuum device
Hole 2, the support frame 3 that 2 lower section integrated setting of stepped hole has center to have through-hole；Sliding is provided with down in the macropore of stepped hole 2
Surface has the valve block 5 of sealing ring 4, and the valve rod 6 connecting with valve block 5 sequentially passes through the aperture of stepped hole 2 and the center of support frame 3
Hole simultaneously extends downwardly, and the end of the valve rod 6 is equipped with retaining ring 7；Above-mentioned valve block 5 and valve rod 6 form the water-blocking component, and block water
For the connected automatic resetting mechanism of part then using the compressed spring 8 being socketed on valve rod 6, which is located at support frame 3 and gear
Between circle 7.
As shown in figure 4, combining and just constituting use described in the utility model above-mentioned inspection head A and the cover B that draws water
In the inspection cover of fire extinguisher air-leakage test.Specifically, drawing water at the top of cover B is pyramidal structure, is not only convenient for and transparent observing cover 1
Bottom is connected, and rises convenient for bubble, and the bottom cover B of drawing water then is tubular construction compatible with fire extinguisher, and lower edge is located at
Below the liquid level in water testing machine pond.Generally, it checks that integrated molding structure can be used in head A and the cover B that draws water, spiral shell can also be used
The form of line connection reduces manufacturing cost in order to replace the model for the cover B that draws water.In order to facilitate realize mechanization batch jobs,
It checks head A and the cover B that draws water is arranged in groups, can be linked to be four cover B that draw water by connecting plate 9 by the way of as shown in Figure 5
One row, an inspection head A is installed at the top cover B of each drawing water, and is matched in the setting of the side of each cover B that draws water with grasping mechanism
The snap-gauge 10 of conjunction.
When carrying out air-leakage test, it will check that cover is socketed on fire extinguisher tank, the cover B lower edge that makes to draw water is located at water testing machine
Then the liquid level in pond is hereinafter, will check that head A is connected with vacuum device；When vacuum device starts, valve block 5 rises, and checks
Air in cover is pumped along valve block 5 and the gap of transparent observing cover 1, and then, the water in pond enters in inspection cover, until
It floods at the top of fire extinguisher；At this point, closing vacuum device, under the action of compressed spring 8, valve rod 6 declines with moving valve plate 5, directly
It is formed and is tightly connected to sealing ring 4 and stepped hole 2；Certain observing time is stopped, if fire extinguisher gas leakage, the bubble generated
Along drawing water, cover B rises, and converges in transparent observing cover 1, is taken pictures using artificial, camera or the modes such as inductor see it
It examines, determine.
