Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0034] It should be noted that when an element is referred to as being “disposed on” or “fixed on” another element, it may be directly on another element or there may be an intervening element. When an element is referred to as being "fixed on" another element, or "fixedly connected" to another element, it may be detachably fixed or non-detachably fixed therebetween. When an element is referred to as being "connected" or "rotatably connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical", "horizontal", "left", "right", "upper", "lower" and similar expressions are used for the purpose of illus...

The invention relates to a preform rod sintering furnace sealing performance test tool, which is used for connecting and sealing a sintering furnace center pipe to be tested, the sintering furnace center pipe to be tested comprises a first pipe section and a second pipe section which are arranged from top to bottom, the bottom of the second pipe section is provided with an air inlet, and the preform rod sintering furnace sealing performance test tool comprises a sealing assembly arranged on a detection pipe; the heat insulation assembly is arranged at the top end of the second pipe section to seal a top end opening of the second pipe section; and one end of the detection tube sequentially penetrates through the sealing assembly and the heat insulation assembly into the sintering furnace center tube. According to the sealing performance testing tool for the preform rod sintering furnace, the heat insulation assembly is arranged at the top end opening of the second pipe section, workers can be prevented from being affected by high temperature during operation, the overall sealing environment is guaranteed through the sealing assembly and the heat insulation assembly, and when the oxygen content in the detection pipe is high at the moment, the sealing performance of the detection pipe is guaranteed. And if so, the central tube of the sintering furnace has a leakage problem, so that the sealing performance of the central tube of the sintering furnace can be tested under the condition that the temperature is not reduced.
Description
technical field [0001] The invention relates to the technical field of airtightness testing, in particular to a tooling and a testing method for airtightness testing of a prefabricated rod sintering furnace. Background technique [0002] In the preform sintering process, process gas needs to be introduced, and the preform is changed from powder to glass rod through high temperature, and impurities and hydroxides inside the glass rod are removed to ensure the quality of the preform. [0003] In sintering production, it is usually necessary to feed helium gas for effective heat transfer, and feed chlorine gas to remove impurities and moisture. Because chlorine gas is highly corrosive, it is easy to reduce the sealing performance of the sintering furnace, and the molecular size of helium gas is small, It is easy to leak, which will lead to a decrease in the yield of the preform. Chlorine gas is toxic and will threaten personal safety after leakage. Therefore, it is necessary to...
