[0003] At present, when installing natural gas pipelines, the short pipes are installed one by one through flanges, which can transport natural gas for long distances. After the connection is completed, it is necessary to test the tightness of the connection, but the current detection device The detection rate is slow, which makes the detection project very time-consuming; therefore, we improve this and propose a fast and accurate leak detection device that does not require pressurization of the device

The invention discloses sealing performance detection equipment, and particularly relates to a rapid and accurate sealing performance detection device without pressurizing a device. The sealing performance detection device comprises a bearing plate, a solid shaft is fixedly arranged in the bearing plate in a sleeved mode, and a left half ring and a right half ring are sequentially and movably sleeved on the outer wall of the solid shaft from left to right. According to the rapid and accurate sealing performance detection device without pressurizing the device, the left half ring and the righthalf ring are arranged, honeycomb nets is arranged inside the left half ring and the right half ring, and liquid chlorine in a box body is conveyed into the two honeycomb nets through inner grooves and conveying holes, the left half ring and the right half ring are wrapped at the flange where the pipeline is connected, so that the methane gas reacts with the chlorine gas, so that the chlorine gason the honeycomb nets changes, so that the sealing performance of the connecting position of the pipeline is detected; due to the fact that the honeycomb net has the adsorbability, the detection result can be quickly known, and the practicability of the detection device is improved.
Description
technical field [0001] The invention relates to a leak detection device, in particular to a fast and accurate leak detection device that does not need to pressurize the device. Background technique [0002] Natural gas pipeline refers to the pipeline that transports natural gas (including associated gas produced in oil fields) from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. [0003] At present, when installing natural gas pipelines, the short pipes are installed one by one through flanges, which can transport natural gas for long distances. After the connection is completed, it is necessary to test the tightness of the connection, but the current detection device The detection rate is slow, which makes the detection project very time-consuming; therefore, we improve this and propose a fast and accurate leak detection device that does not require pressurization of the device.
