<p>Provided is a leak detector that is used in a pipe and can detect a leak and stop fluid from being supplied. The leak detector includes a valve having an internal channel that is selectively closed, a case forming a space for receiving the valve; and a leak pad disposed at a side of the valve and expanding and pressing and moving the valve when the leak pad comes in contact with fluid, in which the valve includes a channel switch portion opening/closing the channel in accordance with rotation positions and a valve cap connected with the channel switch portion and transmits rotation force to the channel switch portion, the valve cap and the case have cap rotation guides corresponding to each other and guide grooves formed at an angle, when the leak pad expands and pushes up the valve, the valve cap is rotated by the cap rotation guides and the guide grooves and rotation force is transmitted to the channel switch portion, such that the channel is closed by the channel switch portion, and a valve seat for installing the valve and guiding the valve moved by the expansion of the leak pad is formed at the case. Accordingly, when a leak is generated, it is possible to more easily detect the leak and effectively close the channel when a leak is detected. Further, the detector can be easily dissembled and installed for reusing.</p> |
