本实用新型涉及密封性检测技术领域,具体为一种压力容器泄露检测装置。The utility model relates to the technical field of sealing detection, specifically a pressure vessel leakage detection device.
背景技术Background technique
压力容器是一种能够承受压力的密闭容器,压力容器的用途极为广泛,它在工业、民用、军工等许多部门以及科学研究的许多领域都具有重要的地位和作用。现如今,常见的压力容器有储存罐、油气罐、空压机罐等。A pressure vessel is a closed container that can withstand pressure. It has a wide range of uses. It plays an important role in many sectors such as industry, civil use, and military industry, as well as in many fields of scientific research. Nowadays, common pressure vessels include storage tanks, oil and gas tanks, air compressor tanks, etc.
压力容器在生产和制造过程中,为了保证每个容器均具有良好的气密性,因此需要经过压力测试才能出厂。传统技术中,检测压力容器密封性的方式一般是将高压气体鼓入容器内,然后再将容器置于水中,观察是否有气泡冒出,若有气泡产生,则说明容器气密性不佳;反之,则说明容器气密性良好。上述方式理论上虽然能够检测出压力容器的气密性,但是必须要工作人员仔细观察;而对于某些容器来说,其裂痕非常轻微,并且泄露速率非常缓慢,因此放入水中产生的气泡也非常细小,工作人员稍不留意,可能就错过了观察气泡的最好时机,进而无法准确判断压力容器是否泄露。为了能够更为直观的判断压力容器是否泄露,我们提出了一种压力容器泄露检测装置以良好的解决上述弊端。During the production and manufacturing process of pressure vessels, in order to ensure that each container has good air tightness, it needs to undergo a pressure test before leaving the factory. In traditional technology, the way to test the sealing of a pressure vessel is to blow high-pressure gas into the container, then place the container in water and observe whether there are bubbles emerging. If there are bubbles, it means the container is not airtight; On the contrary, it means that the container is airtight. Although the above method can theoretically detect the air tightness of the pressure vessel, it must be carefully observed by the staff; for some containers, the cracks are very slight and the leakage rate is very slow, so the bubbles generated when placed in water are also They are very small. If the staff does not pay attention, they may miss the best opportunity to observe the bubbles, and thus cannot accurately determine whether the pressure vessel is leaking. In order to more intuitively determine whether the pressure vessel is leaking, we propose a pressure vessel leakage detection device to effectively solve the above disadvantages.
