Abstract
The invention discloses a protective valve for a device after liquid leakage. The protective valve comprises a valve body, a valve element, a lever, a lever support, a liquid receiving plate and a soaking support, wherein one end of the lever is connected with the valve element, and the other end of the lever is connected with the valve body through a pushing spring; the lever support is provided with a lever fulcrum, and the lever is rotatably connected to the lever fulcrum; one end of the soaking support abuts against the lever, the other end of the soaking support is fixed in the liquid receiving plate, and the soaking support is made of materials which become soft after absorbing water. When the device normally works without leakage, supporting force of the soaking support to the lever and the thrust of the pushing spring to the lever are balanced, and at the moment, a water flow pipeline is at an opened state; when liquid in the device leaks, the leaking liquid flows into the liquid receiving plate, the soaking support becomes soft after absorbing the leaking liquid, so that the soaking support does not support the lever, under the pushing effect of the elasticity of the pushing spring, the lever rotates around the lever fulcrum and drives the valve element to move at the same time, and therefore the water flow pipeline is closed.
Description
Technical field
