Abstract

The invention provides a pipe burst self-closing valve, and belongs to the technical field of city water supply pipe network safety. The pipe burst self-closing valve can effectively solve the valve self-closing problem after pipe burst. The pipe burst self-closing valve comprises an upper valve body and a lower valve body. A valve deck is arranged on the top of the upper valve body with a water outlet, and the valve deck is of a through structure with steps. One end of a switch lever with a reset spring is connected with the valve deck, and a buckle is arranged at the other end of the switch lever. A water inlet is connected with the lower valve body through a straight joint, and a hydraulic cylinder which is parallel to the water inlet is arranged in the middle of the lower valve body. A buckle is arranged at the front end of a piston rod. The hydraulic cylinder is fixedly connected with the lower valve body through a connecting piece. A liquid inlet of the hydraulic cylinder is connected with the water inlet through a hose. A flange piece with a hole is arranged between the upper valve body and the lower valve body. The pipe burst self-closing valve is mainly used in a city water supply pipe network.

Description

technical field [0001] The invention belongs to the technical field of urban water supply network safety, in particular to a technology for automatically closing a valve when a pipe bursts. Background technique [0002] The water supply pipe network is an important urban infrastructure. Its system is huge, with many external interference factors, and the quality of the material and installation quality of the pipe itself varies greatly. This makes the pipe burst accidents of the water supply network common. A pipe burst accident in the water supply network not only damages the water supply equipment, but also causes large-scale flooding, affects production and life, breaks roads, affects public transportation, and causes huge economic losses. After the occurrence of water pipes, there is often a fairly long maintenance window. So we designed this squib water valve to solve this problem. [0003] Judging from the research status at home and abroad, it is mainly aimed at th...
