Description
Изобретение относится к испытаниям изделий на герметичность и может быть использовано для обнаружения утечек в газопроводах.The invention relates to leak testing of products and can be used to detect leaks in gas pipelines.
Известно устройство для обнаружения 5 утечек в газопроводах,содержащее термодатчики, которые устанавливаются в трубопроводах по направлению движения потока, и по их показаниям судят о герметичности изделия I* 1]. 10A device is known for detecting 5 leaks in gas pipelines, containing temperature sensors that are installed in the pipelines in the direction of flow, and judging by their testimony about the tightness of the product I * 1 ]. 10
Недостатком известного устройства является невысокая точность испытаний, связанная с большими погрешностями измерений температуры газа в газопроводе. 15A disadvantage of the known device is the low accuracy of the tests associated with large errors in measuring the temperature of the gas in the gas pipeline. fifteen
Цель изобретения — повышение точности испытаний.The purpose of the invention is improving the accuracy of the tests.
Поставленная цель достигается тем, что устройство снабжено теплоизолиро— .*0 ванной камерой, в которой размещен дат-” чик температуры и которая сообщается с газопроводом через отверстие, при этом диаметр отверстия выбирается из условия обеспечения равенства давлений в камере и газопроводе.This goal is achieved by the fact that the device is equipped with a heat-insulated -. * 0 bath chamber, in which a temperature sensor is placed and which communicates with the gas pipeline through the hole, and the diameter of the hole is selected from the condition of ensuring equal pressures in the chamber and gas pipeline.
На чертеже представлена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Устройство содержит камеру 1, снабженную тепловой изоляцией 2, через отверстие 3 камера 1 сообщается с газопроводом (не показан). В камере 1 размещен датчик 4 температуры, окруженный чехлом 5.The device comprises a chamber 1 provided with thermal insulation 2, through the opening 3, the chamber 1 communicates with a gas pipeline (not shown). A temperature sensor 4 is placed in the chamber 1, surrounded by a cover 5.
Устройство работает следующим образом.The device operates as follows.
При наличии в газопроводе утечки давление’ в нем падает. Через отверстие 3 падение давления распространяется в ко- , меру 1. Теплоизоляция 2 обусловливает адиабатический процесс расширения газа, сопровождающийся падением температуры, которое фиксируется датчикомIf there is a leak in the gas pipeline, the pressure ’in it drops. Through hole 3, the pressure drop propagates to co-, measure 1. Thermal insulation 2 causes an adiabatic process of gas expansion, accompanied by a drop in temperature, which is recorded by the sensor
4. О величине утечки судят по изменению во время температуры.4. The magnitude of the leak is judged by the change during temperature.
Устройство, позволяет достигнуть высокой точности испытаний газопроводов на гермети'чность.The device allows to achieve high accuracy testing of gas pipelines for tightness.
