Abstract: In accordance with the present invention, provided is a multipurpose leak inspection apparatus with easy mass inspection. In the case of valves mass-produced in accordance with an order of a consumer, since a unit price of each valve is low and a large quantity of valves need to be shipped within a short time, there is difficulty in individually checking whether a valve has a leak during a leak inspection to determine whether the valves are produced in a wrong way, and, accordingly, random samples need to be specified among the large quantity of valves and inserted into a leak inspection apparatus to be checked, and, since this type of inspection cannot inspect every valve, the valves need to be replaced after being sold when a defect is discovered, and, in this way, consumers can experience a loss caused by a leak of a valve and can be dissatisfied with the risk of an accident, and an individually checked valve needs to be resent to the consumer, which can lead to an unnecessary cost. In order to solve these issues, the multipurpose leak inspection apparatus comprises a valve leak inspection apparatus part (100), and a smart control part (200). The apparatus quickly inspects mass-produced valves to perform a leak inspection on all the valves instead of performing a sample inspection to determine a valve with a leak before shipment, thereby preventing the shipment of a defective valve; performs a leak inspection through the mixture of produced check and ball valves; performs a leak inspection compatible with sizes of valves; and precisely and conveniently a leak pressure inspection and accurately inspects whether a valve is defective.
