Detailed Description
Example 1
As shown in fig. 1 to 2, the novel air leakage meter of the present invention adopts the technical scheme that the novel air leakage meter comprises a four-way pipe 1, a test element 2, a sealing cover 3, a flow meter 4 and a valve 5; the lower pipe orifice of the four-way pipe 1 is in threaded connection with the testing element 2, the upper pipe orifice of the four-way pipe 1 is in threaded connection with the sealing cover 3, the center of the top of the sealing cover 3 is provided with a hole for fixedly connecting the flowmeter 4, and the left pipe orifice of the four-way pipe 1 is in threaded connection with one end of the valve 5.
The four pipe orifices of the four-way pipe 1 are respectively provided with threads 11.
The center of the lower surface of the test element 2 is provided with an exhaust hole 21.
The four-way pipe 1 is made of stainless steel.
The new air leak detector is provided with a test element 2 with 3 air vents 21 of different apertures.
The utility model discloses a theory of operation: when the device is used, the testing element 2, the sealing cover 3, the flow meter 4 and the valve 5 are respectively arranged at corresponding pipe openings of the four-way pipe 1, the flow meter 4 is arranged at the top of the device and faces upwards vertically, the measuring element 2 is arranged at the bottom, the air flow flowing out of the measuring element 2 is ensured to face downwards vertically, and obstacles are forbidden to be placed below the measuring element 2, so that the pressure measurement value distortion caused by the influence on the smoothness of exhaust is avoided; when the system normally operates, the air outlet of the condenser is in threaded connection with the pipe orifice at the right end of the four-way pipe 1, the valve 5 at the left side is opened, the valve 5 is ensured to be always in an opening state, and the normal operation of the whole vacuum system is ensured; when a flow test is needed, a measuring element 2 with the maximum range is installed, then the valve 5 on the left side is closed slowly, damage to the flowmeter 4 is prevented when the exhaust volume of the system exceeds the range, finally the valve 5 is closed completely, the numerical value of the flowmeter 4 is observed and recorded, in the process, if the reading of the flowmeter 4 exceeds the maximum range, the air leakage volume is too large, the fact that excessive gas exists in the pipeline can be judged, the valve 5 is opened, and the system is checked; if the flow meter 4 is too small in reading, the reading is difficult, the measuring element 2 with a small measuring range is replaced, and the process is repeated until the corresponding flow value is read. The principle of the air leakage instrument is that air at the outlet of a condenser is guided to flow through a measuring element 2 fixedly provided with an exhaust hole 21, an air flow value is displayed according to the relation between a pressure indicating value and the flow rate in a flow meter 4, and then whether the air leakage rate in a system meets the requirement is judged; when the flow test is not needed, the gas is directly discharged to the atmosphere through the valve 5, so that pressure loss is not caused, and the system work is not influenced.
