Abstract
The utility model discloses an equipment protection valve after liquid leakage. The equipment protection valve comprises a valve body, a valve core, a lever, a lever frame, a liquid receiving disk and a soaking support, wherein one end of the lever is connected with the valve core, and the other end is connected with the valve body through an ejection spring; a lever pivot is arranged on the lever frame, and the lever can be rotationally connected to the lever pivot; one end of the soaking support abuts against the lever, the other end is fixed inside the liquid receiving disk, and the soaking support is made of a material softened after water absorption. When equipment does not leak and works normally, a support force applied by the soaking support to the lever is balanced with a thrust force applied by the ejection spring to the lever, and at this moment, a water flowing pipeline is in an open state; when the equipment leaks, a leaked liquid flows into the liquid receiving disk, and the soaking support absorbs the leaked liquid and then is softened, so that the soaking support can not support the lever, under the ejection effect of an elastic force of the ejection spring, the lever rotates around the lever pivot and drives the valve core to move simultaneously, and then the water flowing pipeline is closed.
