Abstract

The invention relates to a cut-off device for a pipeline. The cut-off device comprises a metering impeller, a control mechanism and a stopping piston which is arranged on the pipeline and used for controlling the pipeline to be opened or closed; the two opposite sides of the pipeline are provided with a first cavity and a second cavity which communicate with the pipeline; one end of the stopping piston is arranged in the first cavity through an elastic reset mechanism; when the stopping piston is in a closed state, the other end of the stopping piston is located in the second cavity and forms a pressure chamber with the inner side wall of the second cavity; the pressure chamber communicates with the pipeline through a pressure backflow pipe, and the end, communicating with the pipeline, of the pressure backflow pipe is located on the down stream of the stopping piston; the metering impeller is arranged in the pipeline and located on the up stream of the stopping piston; the stopping piston is provided with a capillary hole and a through hole; and the side wall of the first cavity is provided with a limiting mechanism used for locking the stopping piston. According to the cut-off device for the pipeline, a good anti-overflow effect can be achieved, and safety accidents and water resource waste which are caused by the fact that a user forgets turning off a spigot are avoided.

Description

technical field [0001] The invention belongs to the technical field of pipeline interceptors, and in particular relates to a pipeline interceptor. Background technique [0002] The water pipes in existing households mainly control the on / off of the pipes through the faucet. When you forget to turn off the faucet, especially when you encounter a water outage, you forget to turn off the faucet after turning on the faucet and no water comes out. The faucet is open. [0003] Although the existing pools are usually equipped with overflows, since the water flowing out of the faucet is sprayed under the action of the water supply pressure in the water pipe, its water injection speed is greater than the drainage speed of the overflow port, so when it meets the water pipe When the road is blocked, if no one finds it in time, the tap that is forgotten to turn off will cause water to overflow from the pool, which will not only cause safety accidents and economic losses, but also cause...
