Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
Referring to fig. 1, the cylinder of the aviation oil water measurer comprises a chemical water measurer joint 1, a shell 2 with openings at two ends, a transparent inner container 3 with openings at two ends, and a piston assembly. The head of the chemical water meter connector 1 is used for connecting a chemical water meter, and after oil passes through the chemical water meter, whether the oil contains water or not and the approximate water content are determined according to the color of the changed test paper. The chemical water measurer joint 1 is arranged at one end of the shell 2, and the inner container 3 is arranged in the shell 2. The piston assembly can stretch out and draw back in the inner container 3 and is used for pumping oil into the inner container 3 from the chemical water meter connector 1. The shell 2 is provided with a window 21 along the extension direction of the piston assembly. The piston assembly and the other end of the shell 2 are locked through a fixing nut 4, and after the fixing nut 4 is locked, the two ends of the inner container 3 can be tightly pressed between the chemical water meter connector 1 and the fixing nut 4 in a sealing mode. When the piston assembly is pulled, oil can enter the joint of the chemical water meter through the chemical water meter and then be pulled into the liner 3 through the opening of the shell and the opening of the liner. The tester can look over the volume of oil pumping in the inner bag through the window. In order to accurately know the amount of oil pumped in, the inner container 3 is provided with scales at the visible part of the window 21.
The bottom of the chemical water meter connector 1 is provided with a connecting sheet 11 (shown in figure 3), and the diameter of the connecting sheet 11 is larger than the opening size of the shell 2. The connecting sheet 11 is arranged in the shell 2, and the joint head end of the chemical water meter extends out of the shell to be connected with the chemical water meter. The chemical water meter is an existing chemical water meter structure and is not described in detail herein. The connecting sheet 11 is large enough to cover the whole opening of the casing, and after the fixing screw cap 4 is locked, the inner container 3 tightly props against the connecting sheet 11, so that the connecting sheet is tightly attached to the casing, and the oil product is prevented from overflowing. In order to improve the tightness of the liner against the shell, a first sealing ring is arranged between the liner 3 and the shell 1, and the first sealing ring is a rubber sealing ring. Specifically, the first sealing ring is arranged between the connecting sheet 11 and the liner 3, so that the liner can tightly support the connecting sheet 11 in a sealing manner, and oil products are prevented from overflowing from the liner 3.
The piston assembly comprises an inner rod 5, a piston 6, a gasket 7, an outer rod 8 and a handle 9. One end of the inner rod 5 is provided with threads for connecting the handle 9 in a threaded manner, and the other end of the inner rod 5 is provided with a top plate 51 (shown in figure 2). The piston 6 and the gasket 7 are both sleeved on the inner rod 5, and the piston 6 is arranged between the top plate 51 and the gasket 7. The outer rod 8 is sleeved outside the inner rod 5, when the handle 9 locks the inner rod 5, two ends of the outer rod 8 are tightly pressed between the handle 9 and the gasket 7, and the piston 6 is tightly pressed between the top plate 51 and the gasket 7. The inner rod 5 and the outer rod 8 extend into the inner container 3 from the through hole 41 of the fixing nut 4 and stretch in the inner container 3 to drive the piston 6 to move in the inner container 3. The tester screws the handle 9 to the end of the inner rod 5, so that the handle 9 extrudes the outer rod 8 towards the piston 6 until the piston is compressed, and the piston assembly can effectively extract oil.
The piston 6 includes a first piston head 61, a second piston head 63, and a spacer 62. The spacer 62 is provided between the first piston head 61 and the second piston head 63. The first piston head 61, the second piston head 63 and the spacer 62 are single independent parts and are combined into a whole piston structure through connection. Therefore, the extrusion effect is better, the labor is saved, two ends of the piston can expand for two circles after being pressed, and the sealing effect is better. The piston may also have only the first head and the second head as a single integral molded part, thus requiring a greater compression force. The first piston head 61 and the second piston head 63 are rubber piston heads. The spacer 62 is a rubber ring.
The inner container 3 is a glass inner container, on one hand, the inner container is visible, on the other hand, the inner container wall is smooth, the resistance is small, and the piston assembly is more labor-saving when being pulled. In addition, the glass liner is easy to clean and can be used repeatedly.
The shell 2, the chemical water meter connector 1, the fixing screw cap 4, the inner rod 5, the outer rod 8 and the handle 9 can be made of stainless steel materials, and the chemical water meter connector is long in service life and durable. The shell can be carved with 5ML scale lines. And under the condition that the scales of the inner container cannot be clearly seen, quickly extracting and detecting oil products with required quantity through the scale marks outside the shell.
The cylinder of the aviation oil water measurer also comprises a locking nut 10. The outer rod 8 is a screw. The locking nut 10 is sleeved outside the outer rod 8, the outer diameter of the locking nut 10 is larger than the opening size of the through hole 41, and is larger than the opening size of the handle 10 for locking the end part of the inner rod 5. After the inner rod 5 is locked by the handle 10 to tightly push the piston, the locking nut can be screwed to a proper position to limit the handle 10, so that the handle 10 is prevented from being further screwed in.
One side of the outer rod 8 is flattened along the length direction. The through hole 41 is an arch hole matched with the shape of the outer rod 8. In this way, the direction of the outer rod passing through the through hole 41 of the fixing nut 4 is restricted and rotation is prevented when the piston assembly is withdrawn. In addition, the flattening side of the outer rod is provided with scales, so that accurate sampling is facilitated.
In order to improve the sealing performance at the through hole, a second sealing ring is arranged between the inner container 3 and the fixing nut 4. The second sealing ring adopts rubber seal, can avoid the air to get into from the through-hole department at the pull in-process, influences oil pull effect and precision then.
When in use, the handle is twisted clockwise to jack the piston tightly, and the locking nut is fixed after air leakage does not occur. After the use, the locking nut is loosened anticlockwise, and the handle is loosened anticlockwise.
It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention. The objects of the present invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
