Abstract

The invention discloses a pipeline safety break-off device. A hydraulic oil cylinder pipeline is fixed to a support, one end of a telescopic positive pipe is inserted into the hydraulic oil cylinder pipeline and is in sliding connection with the hydraulic oil cylinder pipeline, and the other end of the telescopic positive pipe is provided with a positive valve. A valve rod of the positive valve is fixedly connected with a first transmission gear, and a positive end opening is formed in the other end of the telescopic positive pipe. A fixed negative pipe is fixed to the support, a negative valve is arranged at one end of the fixed negative pipe, and a valve rod of the negative valve is fixedly connected with a second transmissions gear. The second transmission gear is fixedly connected with a rotary shaft of a rotary oil cylinder, a cylinder body of the rotary oil cylinder is fixedly connected with the support, a negative end opening matched with the positive end opening is formed in one end of the fixed negative pipe, and the first transmission gear and the second transmission gear are located on the same horizontal plane. A telescopic oil cylinder is fixedly connected with the support and connected with the telescopic positive pipe through a pipeline. The pipeline safety break-off device can effectively prevent fires from spreading and expanding.

Description

technical field [0001] The invention belongs to the field of pipeline safety, in particular to a pipeline safety disconnection device. Background technique [0002] The large storage tanks containing crude oil and other dangerous chemicals in the tank area are arranged in a centralized manner, and the storage tanks and the use end are connected by pipelines to transport materials. When a fire or other disaster occurs at one end, it is necessary to cut off the pipeline and stop the transportation to prevent the fire from spreading and reduce losses. But the existing pipeline does not have a fire warning system, and the pipeline cannot be cut off automatically at any time, which easily expands the area of ​​the accident and increases the loss. Contents of the invention [0003] The object of the present invention is to provide a pipeline safety disconnecting device that automatically disconnects connected pipelines according to requirements and prevents fire from spreading....
